BACKGROUND OF THE INVENTION
The invention also provides pharmaceutically acceptable compositions comprising compounds of the present invention and methods of using said compositions in the treatment of various disorders.
BACKGROUND OF THE INVENTION
[0003] The search for new therapeutic agents has been greatly aided in recent years by a better understanding of the structure of enzymes and other biomolecules associated with diseases. One important class of enzymes that has been the subject of extensive study is protein kinases.
[0004] Protein kinases constitute a large family of structurally related enzymes that are responsible for the control of a variety of signal transduction processes within the cell. Protein kinases are thought to have evolved from a common ancestral gene due to the conservation of their structure and catalytic function. Almost all kinases contain a similar 250-300 amino acid catalytic domain. The kinases may be categorized into families by the substrates they phosphorylate (e.g., protein-tyrosine, protein-serine/threonine, lipids, etc.).
[0005] In general, protein kinases mediate intracellular signaling by effecting a phosphoryl transfer from a nucleoside triphosphate to a protein acceptor that is involved in a signaling pathway. These phosphorylation events act as molecular on/off switches that can modulate or regulate the target protein biological function. These phosphorylation events are ultimately triggered in response to a variety of extracellular and other stimuli.
Examples of such stimuli include environmental and chemical stress signals (e.g., osmotic shock, heat shock, ultraviolet radiation, bacterial endotoxin, and H202), cytokines (e.g., interleukin-1 (IL-1) and tumor necrosis factor a (TNF-a)), and growth factors (e.g., granulocyte macrophage-colony-stimulating factor (GM-CSF), and fibroblast growth factor (FGF)). An extracellular stimulus may affect one or more cellular responses related to cell growth, migration, differentiation, secretion of hormones, activation of transcription factors, muscle contraction, glucose metabolism, control of protein synthesis, and regulation of the cell cycle.
[00061 Many diseases are associated with abnormal cellular responses triggered by protein kinase-mediated events as described above. These diseases include, but are not limited to, autoimmune diseases, inflammatory diseases, bone diseases, metabolic diseases, neurological and neurodegenerative diseases, cancer, cardiovascular diseases, allergies and asthma, Alzheimer's disease, and hormone-related diseases. Accordingly, there remains a need to find protein kinase inhibitors useful as therapeutic agents.

Such diseases, disorders, or conditions include those described herein.

[00341 As used herein, the term "pharmaceutically acceptable salt" refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio.
Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange.
Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like.
[00351 Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N+(Cl 4alkyl)4 salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate.
[00361 Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S configurations for each asymmetric center, Z and E double bond isomers, and Z and E conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention.
Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures including the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a 13C- or 14C-enriched carbon are within the scope of this invention.
Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present invention. In some embodiments, the Rl group of formula I-a and I-b comprises one or more deuterium atoms.
[00371 As used herein, the term "irreversible" or "irreversible inhibitor"
refers to an inhibitor (i.e. a compound) that is able to be covalently bonded to a target protein kinase in a substantially non-reversible manner. That is, whereas a reversible inhibitor is able to bind to (but is generally unable to form a covalent bond) the target protein kinase, and therefore can become dissociated from the target protein kinase, an irreversible inhibitor will remain substantially bound to the target protein kinase once covalent bond formation has occurred. Irreversible inhibitors usually display time dependency, whereby the degree of inhibition increases with the time with which the inhibitor is in contact with the enzyme. Methods for identifying if a compound is acting as an irreversible inhibitor are known to one of ordinary skill in the art. Such methods include, but are not limited to, enzyme kinetic analysis of the inhibition profile of the compound with the protein kinase target, the use of mass spectrometry of the protein drug target modified in the presence of the inhibitor compound, discontinuous exposure, also known as "washout,"
experiments, and the use of labeling, such as radiolabelled inhibitor, to show covalent modification of the enzyme, as well as other methods known to one of skill in the art.
[00381 One of ordinary skill in the art will recognize that certain reactive functional groups can act as "warheads." As used herein, the term "warhead" or "warhead group"
refers to a functional group present on a compound of the present invention wherein that functional group is capable of covalently binding to an amino acid residue (such as cysteine, lysine, histidine, or other residues capable of being covalently modified) present in the binding pocket of the target protein, thereby irreversibly inhibiting the protein. It will be appreciated that the -L-Y group, as defined and described herein, provides such warhead groups for covalently, and irreversibly, inhibiting the protein.
[00391 As used herein, the term "inhibitor" is defined as a compound that binds to and /or inhibits the target protein kinase with measurable affinity. In certain embodiments, an inhibitor has an IC50 and/or binding constant of less about 50 M, less than about 1 M, less than about 500 nM, less than about 100 nM, or less than about 10 nM, [00401 The terms "measurable affinity" and "measurably inhibit," as used herein, means a measurable change in at least one of ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3 activity between a sample comprising a compound of the present invention, or composition thereof, and at least one of ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, and an equivalent sample comprising at least one of ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, in the absence of said compound, or composition thereof.

[00111] As defined generally above, R' is a warhead group, or, when R' and Rx form a ring, then -Q-Z is a warhead group. Without wishing to be bound by any particular theory, it is believed that such R' groups, i.e. warhead groups, are particularly suitable for covalently binding to a key cysteine residue in the binding domain of certain protein kinases.
Protein kinases having a cysteine residue in the binding domain are known to one of ordinary skill in the art and include ErbBI, ErbB2, and ErbB4, or a mutant thereof. In certain embodiments, compounds of the present invention have a warhead group characterized in that inventive compounds target one or more of the following cysteine residues:
[00112] Thus, in some embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue thereby irreversibly inhibiting the enzyme. In certain embodiments, the cysteine residue is Cys797 of ErbB 1, Cys805 of ErbB2 and Cys803 of ErbB4, or a mutant thereof, where the provided residue numbering is in accordance with Uniprot (code P00533 for ErbBl; code P04626 for ErbB2, and Q15303 for ErbB4). It will be understood that the Cys of ErbB 1 (EGFR) is variably called 773 or 797 depending on whether the parent sequence contains the signal peptide or not. Thus, in accordance with the present invention, the relevant cysteine residue of ErbB 1 may be described as Cys 773 or Cys 797 and these terms are used interchangeably.
[00113] One of ordinary skill in the art will recognize that a variety of warhead groups, as defined herein, are suitable for such covalent bonding. Such R' groups include, but are not limited to, those described herein and depicted in Table 4, infra.
[00114] As depicted in formulae I-a and I-b supra, the R' warhead group can be in an ortho-, meta-, or para-position. In certain embodiments, the R' warhead group is in a meta-position of the phenyl ring relative to the rest of the molecule.
[00115] In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of TEC, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 449.
[001161 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of BTK, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 481.
[001171 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of ITK, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 442.
[001181 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of BMX, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 496.
[001191 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of JAK3, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 909.
[001201 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of TXK, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 350.
[001211 One of ordinary skill in the art will recognize that a variety of warhead groups, as defined herein, are suitable for such covalent bonding. Such R' groups include, but are not limited to, those described herein and depicted in Table 3, infra.

[001401 Most preferably, pharmaceutically acceptable compositions of this invention are formulated for oral administration.
[001411 The amount of compounds of the present invention that may be combined with the carrier materials to produce a composition in a single dosage form will vary depending upon the host treated, the particular mode of administration. Preferably, provided compositions should be formulated so that a dosage of between 0.01 - 100 mg/kg body weight/day of the inhibitor can be administered to a patient receiving these compositions.
[001421 It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease being treated. The amount of a compound of the present invention in the composition will also depend upon the particular compound in the composition.
Uses of Compounds and Pharmaceutically Acceptable Compositions [001431 Compounds and compositions described herein are generally useful for the inhibition of protein kinase activity of one or more enzymes.
[001441 Drug resistance is emerging as a significant challenge for targeted therapies. For example, drug resistance has been reported for Gleevec and Iressa , as well as several other kinase inhibitors in development. In addition, drug resistance has been reported for the cKit and PDGFR receptors. It has been reported that irreversible inhibitors may be effective against drug resistant forms of protein kinases (Kwak, E. L., R. Sordella, et al. (2005).
"Irreversible inhibitors of the EGF receptor may circumvent acquired resistance to gefitinib." PNAS
102(21): 7665-7670.) Without wishing to be bound by any particular theory, it is believed that compounds of the present invention may be effective inhibitors of drug resistant forms of protein kinases.
[001451 As used herein, the term "clinical drug resistance" refers to the loss of susceptibility of a drug target to drug treatment as a consequence of mutations in the drug target.
[001461 As used herein, the term "resistance" refers to changes in the wild-type nucleic acid sequence coding a target protein, and/or the protein sequence of the target, which changes decrease or abolish the inhibitory effect of the inhibitor on the target protein.
[001471 Examples of kinases that are inhibited by the compounds and compositions described herein and against which the methods described herein are useful include ErbB
1, ErbB2, ErbB3, ErbB4, a TEC-kinase (including BTK, ITK, TEC, BMX and RLK), and/or JAK3, or a mutant thereof.
[001481 The activity of a compound utilized in this invention as an inhibitor of ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof, may be assayed in vitro, in vivo or in a cell line. In vitro assays include assays that determine inhibition of either the phosphorylation activity and/or the subsequent functional consequences, or ATPase activity of activated ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof.
Alternate in vitro assays quantitate the ability of the inhibitor to bind to ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3. Inhibitor binding may be measured by radiolabeling the inhibitor prior to binding, isolating the inhibitor/ErbB1, inhibitor/ErbB2, inhibitor/ErbB3, inhibitor/ErbB4, inhibitor/TEC-kinase (i.e., TEC, BTK, ITK, RLK and BMX), or inhibitor/JAK3 complex and determining the amount of radiolabel bound. Alternatively, inhibitor binding may be determined by running a competition experiment where new inhibitors are incubated with ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3 bound to known radioligands.
Detailed conditions for assaying a compound utilized in this invention as an inhibitor of ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof, are set forth in the Examples below.
[001491 Protein tyrosine kinases are a class of enzymes that catalyze the transfer of a phosphate group from ATP or GTP to a tyrosine residue located on a protein substrate. Receptor tyrosine kinases act to transmit signals from the outside of a cell to the inside by activating secondary messaging effectors via a phosphorylation event. A variety of cellular processes are promoted by these signals, including proliferation, carbohydrate utilization, protein synthesis, angiogenesis, cell growth, and cell survival.
(a) ErbB Family [001501 ErbB receptors, a major family of receptor tyrosine kinases, are composed of an extracellular ligand binding domain, a single transmembrane domain, and an intracellular domain with tyrosine kinase activity. The ErbB family comprises ErbBI
(commonly known as EGFR), ErbB2 (commonly known as HER2 or neu), ErbB3 (commonly known as HER3), and ErbB4 (commonly known as HER4). More than 10 ligands (including EGF, TGFa, AR, BTC, EPR, HB-EGF, NRG-l, NRG-2, NRG-3, NRG-4) have been identified for the various receptor family members. Upon ligand binding the extracellular domain undergoes conformational change, allowing the formation of homodimers or heterodimers with other members of the ErbB
family. Dimerization induces tyrosine phosphorylation of specific residues in the intracellular domain that serve as docking sites for adaptor proteins and downstream effectors. In some contexts, activation of phosphatidyl-inositol 3-kinase (P13K) and mitogen-activated protein kinase pathways occur, leading to cell proliferation and survival (Lin, N. U.;
Winer, E. P., Breast Cancer Res 6: 204-210, 2004).
[001511 Interaction between family members is necessitated by deficiencies in ErbB2, which has no known ligand, and ErbB3, which is kinase dead. EGFR, ErbB3, and ErbB4 bind ligand to induce ErbB receptor homodimerization or heterodimerization, whereas ErbB2 functions as the preferred dimerization partner. The composition of the pairwise combinations is important for signal diversification, as dimer identity determines which downstream pathways are activated.
Representative downstream gene products in the ErbB signal transduction pathway include She, Grb2, SOS I, Ras, Rafl, Mek, ERK1, ERK2, ERa, Akt, mTOR, FKHR, p27, Cyclin Dl, FasL, GSK-3, Bad, and STAT3.
[001521 There is strong precedent for involvement of the EGFR and other members of the ErbB family in human cancer because over 60% of all solid tumors overexpress at least one of these proteins or their ligands. Constitutively active, tumorigenic EGFR All, a mutant possessing a truncated extracellular domain, has been reported to be present in up to 78% of breast carcinomas and has also been found in glioblastomas. Overexpression of EGFR is commonly found in breast, lung, head and neck, bladder tumors, while ErbB2 expression is frequently elevated in human tumors of epithelial origin. Activating mutations in the tyrosine kinase domain have been identified in patients with non-small cell lung cancer (Lin, N. U.;
Winer, E. P., Breast Cancer Res 6: 204-210, 2004). ErbB l and/or ErbB2 amplification has also been implicated in squamous cell carcinomas, salivary gland carcinomas, ovarian carcinomas, and pancreatic cancers (Cooper, G.C. Oncogenes. 2nd ed. Sudbury: Jones and Barlett, 1995;
Zhang, Y., et al., Cancer Res 66 : 1025-32, 2006). Overexpression of ErbB2 has potent transforming activity, likely due to its ability to cooperate with other ErbB
receptors (Sherman, L., et al., Oncogene 18: 6692-99, 1999). In fact, some human cancers that overexpress both EGFR and ErbB2 have a poorer prognosis than cancers that overexpress either receptor alone.
[001531 The ErbB signaling network is often a key component in the pathogenesis of breast cancer. Amplification of ErbB2 is associated with an aggressive tumor phenotype that is characterized by relatively rapid tumor growth, metastatic spread to visceral sites, and drug resistance. ErbB2 has been shown to be amplified in 20% of axillary node-negative ("ANN") breast cancer cases, and this amplification has been identified as an independent prognostic factor for risk of recurrence in ANN breast cancer. (Andrulis, I.L., et al., J
Clin Oncol 16: 1340-9, 1998).
[001541 Targeted blockade of ErbB signaling with trastuzumab (Herceptin), a monoclonal antibody directed at ErbB2, has been shown to improve survival in women with ErbB2-positive, advanced breast cancer. Other monoclonal antibodies directed against ErbB
receptors include cetuximab (Erbitux) and panitumumab (Vectibix).
[001551 Several small molecule tyrosine kinase inhibitors (TKIs) have been found to act selectively upon ErbB family members. Notable examples include gefitinib (Iressa) and erlotinib (Tarceva), both of which target the EGFR. These small molecules compete with ATP
for binding to the kinase domain of the receptor. Compared to monoclonal antibodies, TKIs have several advantages in that they are orally bioavailable, well-tolerated, and appear to be active against truncated forms of ErbB2 and EGFR receptors (e.g., EGFR vlll) in vitro. In addition, the small size of small molecule TKIs may allow them to penetrate sanctuary sites such as the central nervous system. Finally, the homology between kinase domains of ErbB receptors allows for development of TKIs that target more than one member of the ErbB
family simultaneously, the advantages of which are described herein.
[00156] Although certain malignancies have been linked to the overexpression of individual receptors, efficient signal transduction relies on the coexpression of ErbB
receptor family members. This cooperation of ErbB receptor family members in signal transduction and malignant transformation may limit the success of agents that target individual receptors in the treatment of cancer; a potential mechanism of resistance to agents targeting a single ErbB
receptor is upregulation of other members of the receptor family (Britten, C.
D., Mol Cancer Ther 3: 1335-42, 2004).
[00157] Agents that target two or more ErbB receptors are called pan-ErbB
regulators. ERRP
is a pan-ErbB negative regulator that is expressed in most benign pancreatic ductal epithelium and islet cells. Tumors have been found to experience a progressive loss in ERRP expression.
That Erbitux and Herceptin show success in a limited patient base (tumors having increased expression of EGFR or ErbB2) could be partly due to coexpression of multiple ErbB family members.
[00158] In both in vitro and in vivo models, strategies that employ a dual ErbB approach seem to have greater antitumor activity than agents targeting a single ErbB
receptor. Thus, agents that target multiple members of ErbB family are likely to provide therapeutic benefit to a broader patient population (Zhang, Y., et al., Cancer Res 66: 1025-32, 2006). In certain embodiments, provided compounds inhibit one or more of ErbBl, ErbB2, ErbB3, and ErbB4. In some embodiments, provided compounds inhibit two or more of ErbB 1, ErbB2, ErbB3, and ErbB4, or a mutant thereof, and are therefore pan-ErbB inhibitors.
[00159] Clearly, there is growing evidence to support the concurrent inhibition of two or more ErbB (i.e., pan-ErbB) receptors in cancer therapy. Possible pan-ErbB
approaches with small molecules include using combinations of agents that target individual ErbB
receptors, using single agents that target multiple ErbB receptors, or using agents that interfere with ErbB
receptor interactions (e.g., dimerization). Additional strategies include therapies utilizing a small molecule in combination with antibodies, or chemoprevention therapies (Lin, N.
U.; Winer, E.
P., Breast Cancer Res 6: 204-210, 2004).
[00160] An example of small molecule pan-ErbB inhibition is CI-1033, an irreversible pan-ErbB inhibitor that covalently binds to the ATP binding site of the intracellular kinase domain.
Another irreversible pan-ErbB receptor tyrosine kinase inhibitor is HKI-272, which inhibits the growth of tumor cells that express ErbB-1 (EGFR) and ErbB-2 (HER-2) in culture and xenografts, and has antitumor activity in HER-2-positive breast cancer (Andrulis, I.L., et al., J
Clin Oncol 16: 1340-9, 1998). Irreversible inhibitors have demonstrated superior antitumor activity in comparison with reversible inhibitors.
[001611 Neurofibromatosis type I (NFI) is a dominantly inherited human disease affecting one in 2500-3500 individuals. Several organ systems are affected, including bones, skin, iris, and the central nervous system, as manifested in learning disabilities and gliomas. A hallmark of NF I is the development of benign tumors of the peripheral nervous system (neurofibromas), which vary greatly in both number and size among patients. Neurofibromas are heterogeneous tumors composed of Schwann cells, neurons, fibroblasts and other cells, w/
Schwann cells being the major (60-80%) cell type.
[001621 Abberant expression of the EGFR is associated with tumor development in NF 1 and in animal models of NFl, suggesting a role in pathogenesis and representing a novel potential therapeutic target. EGFR expression affects the growth of tumor cell lines derived from NF1 patients under conditions where EGF is not the primary factor driving growth of the cells. These data suggest that EGFR may play an important role in NFl tumorigenesis and Schwann cell transformation (DeClue, J. E., et al., J Clin Invest 105: 1233-41, 2000).
[001631 Patients with NFI develop aggressive Schwann cell neoplasmas known as malignant peripheral nerve sheath tumors (MPNSTs). Schwann cells are the major supportive cell population in the peripheral nervous system. Neoplastic Schwann cells within these neoplasms variably express the ErbB tyrosine kinases mediating NRG-l responses (ErbB2, ErbB3, ErbB4).
Neuregulin-1 (NRG-1) proteins promote the differentiation, survival, and/or proliferation of many cell types in the developing nervous system, and overexpression of NRG-1 in myelinating Schwann cells induces the formation of malignant peripheral nerve sheath tumors (MPNSTs) (Fallon, K. B., et al., J Neuro Oncol 66: 273-84, 2004).
[001641 Deregulation of Schwann cell growth is a primary defect driving the development of both benign neurofibromas and MPNST in neurofibromatosis type I (NF 1) patients. Growth of MPNSTs and transformed mouse Schwann cells in vitro is highly EGF-dependent and can be blocked by EGFR inhibitors under conditions where EGF is the primary growth factor. Some human MPNST cell lines have been found to demonstrate constitutive ErbB
phosphorylation.
While treatment with ErbB inhibitors abolishes ErbB phosphorylation and reduces DNA
synthesis in these lines, effective chemotherapeutic regimens for MPNST remain elusive (Stonecypher, M. S., et al., Oncogene 24: 5589-5605, 2005).
[001651 Schwannomas are peripheral nerve tumors comprised almost entirely of Schwann-like cells, and typically have mutations in the neurofibromatosis type II
(NF2) tumor suppressor gene. Ninety percent of NF2 patients develop bilateral vestibular schwannomas and/or spinal schwannomas. Enlarging schwannomas can compress adjacent structures, resulting in deafness and other neurologic problems. Surgical removal of these tumors is difficult, often resulting in increased patient morbidity.
[001661 Both normal human Schwann cells and schwannoma cells express neuregulin receptors (i.e., ErbB receptors), and schwannoma cells proliferate in response to neuregulin. It is possible that aberrant neuregulin production or response contributes to aberrant schwannoma cell proliferation (Pelton, P. D., et al., Oncogene 17: 2195-2209, 1998).
[001671 The NF2 tumor suppressor, Merlin, is a membrane/cytoskeleton-associated protein implicated in the regulation of tyrosine kinase activity. Genetic interactions between a Merlin mutation and EGFR pathway mutations have been documented in Drosophila (LaJeunesse, D.
R., et al., Genetics 158: 667-79, 2001). Other evidence suggests Merlin can inhibit EGFR
internalization and signaling upon cell-cell contact by restraining the EGFR
into a membrane compartment from which it can neither signal nor be internalized (McClatchey, A. I., et al., Genes and Development 19: 2265-77, 2005; Curto, M. C., et al., J Cell Biol 177: 893-903, 2007).
[001681 As used herein, the terms "treatment," "treat," and "treating" refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment may be administered after one or more symptoms have developed. In other embodiments, treatment may be administered in the absence of symptoms. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example to prevent or delay their recurrence.
[001691 Provided compounds are inhibitors of one or more of ErbBl, ErbB2, ErbB3, and ErbB4 and are therefore useful for treating one or more disorders associated with activity of one of more of ErbB 1, ErbB2, ErbB3, and ErbB4. Thus, in certain embodiments, the present invention provides a method for treating an ErbB I -mediated, an ErbB2-mediated, an ErbB3-mediated, and/or ErbB4-mediated disorder comprising the step of administering to a patient in need thereof a compound of the present invention, or pharmaceutically acceptable composition thereof.
[001701 As used herein, the terms "ErbB I -mediated", "ErbB2-mediated," "ErbB3-mediated,"
and/or "ErbB4-mediated" disorders or conditions as used herein means any disease or other deleterious condition in which one or more of ErbBI, ErbB2, ErbB3, and/or ErbB4, or a mutant thereof, are known to play a role. Accordingly, another embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which one or more of ErbB 1, ErbB2, ErbB3, and/or ErbB4, or a mutant thereof, are known to play a role. Specifically, the present invention relates to a method of treating or lessening the severity of a disease or condition selected from a proliferative disorder, wherein said method comprises administering to a patient in need thereof a compound or composition according to the present invention.
[001711 In some embodiments, the present invention provides a method for treating or lessening the severity of one or more disorders selected from a cancer. In some embodiments, the cancer is associated with a solid tumor. In certain embodiments, the cancer is breast cancer, glioblastoma, lung cancer, cancer of the head and neck, colorectal cancer, bladder cancer, or non-small cell lung cancer. In some embodiments, the present invention provides a method for treating or lessening the severity of one or more disorders selected from squamous cell carcinoma, salivary gland carcinoma, ovarian carcinoma, or pancreatic cancer.
[001721 In certain embodiments, the present invention provides a method for treating or lessening the severity of neurofibromatosis type I (NF 1), neurofibromatosis type II (NF2) Schwann cell neoplasms (e.g. MPNST's), or Schwannomas.
(b) TECFamily [001731 The TEC family of non-receptor tyrosine kinases, referred to herein as "TEC-kinases," plays a central role in signaling through antigen-receptors such as the TCR, BCR and Fc receptors (reviewed in Miller A, et al. Current Opinion in Immunology 14;
331-340 (2002).
TEC-kinases are essential for T cell activation. Three members of the family, Itk, Rlk and, are activated downstream of antigen receptor engagement in T cells and transmit signals to downstream effectors, including PLC-y. Combined deletion of Itk and Rlk in mice leads to a profound inhibition of TCR responses including proliferation, cytokine production and immune responses to an intracellular parasite (Toxoplasma gondii) (Schaeffer et al., Science 284; 638-641 (1999)). Intracellular signalling following TCR engagement is effected in ITK/RLK
deficient T cells; inositol triphosphate production, calcium mobilization and MAP kinase activation are all reduced. Tec-kinases are also essential for B cell development and activation.
[001741 TEC-kinases include five family members, which are expressed primarily in hematopoietic cells: TEC, BTK, ITK (also known as TSK and EMT), RLK (also known as TXK), and BMX (also known as ETK). Additional related TEC-kinases have been found in Drosophila melanogaster, zebrafish (Danio rerio), skate (Raja eglanteria), and sea urchin (Anthocidaris crassispina).
[001751 Provided compounds are inhibitors of one of more TEC-kinases and are therefore useful for treating one or more disorders associated with activity of one or more TEC-kinases.
Thus, in certain embodiments, the present invention provides a method for treating a TEC-mediated disorder comprising the step of administering to a patient in need thereof a compound of the present invention, or pharmaceutically acceptable composition thereof.
[001761 The term "TEC-mediated condition", as used herein means any disease or other deleterious condition in which TEC-kinases are known to play a role. Such conditions include those described herein and in Melcher, M et al., "The Role of TEC Family Kinases in Inflammatory Processes", Anti-Inflammatory & Anti-Allergy Agents in Medicinal Chemistry, Vol. 6, No. 1, pp. 61-69 (Feb. 2007). Accordingly, another embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which TEC-kinases are known to play a role. Specifically, the present invention relates to a method of treating or lessening the severity of a disease or condition selected from autoimmune, inflammatory, proliferative, and hyperproliferative diseases and immunologically-mediated diseases including rejection of transplanted organs or tissues and Acquired Immunodeficiency Syndrome (AIDS)(also known as HIV), wherein said method comprises administering to a patient in need thereof a composition of the present invention.

(c) Bruton's tyrosine kinase (BTK) [001841 Bruton's tyrosine kinase ("BTK"), a member of TEC-kinases, is a key signaling enzyme expressed in all hematopoietic cell types except T lymphocytes and natural killer cells.
BTK plays an essential role in the B-cell signaling pathway linking cell surface B-cell receptor (BCR) stimulation to downstream intracellular responses.
[001851 BTK is a key regulator of B-cell development, activation, signaling, and survival (Kurosaki, Curr Op Imm, 2000, 276-281; Schaeffer and Schwartzberg, Curr Op Imm 2000, 282-288). In addition, BTK plays a role in a number of other hematopoietic cell signaling pathways, e.g., Toll like receptor (TLR) and cytokine receptor-mediated TNF-a production in macrophages, IgE receptor (Fc_epsilonRI) signaling in mast cells, inhibition of Fas/APO-1 apoptotic signaling in B-lineage lymphoid cells, and collagen-stimulated platelet aggregation. See, e.g., C.
A. Jeffries, et al., (2003), Journal of Biological Chemistry 278:26258-26264;
N. J. Horwood, et al., (2003), The Journal of Experimental Medicine 197: 1603- 1611 ; Iwaki et al. (2005), Journal of Biological Chemistry 280(48):40261 -40270; Vassilev et al. (1999), Journal of Biological Chemistry 274(3): 1646-1656, and Quek et al. (1998), Current Biology 8(20):
1137-1140.
[001861 Patients with mutations in BTK have a profound block in B cell development, resulting in the almost complete absence of mature B lymphocytes and plasma cells, severely reduced Ig levels and a profound inhibition of Immoral response to recall antigens (reviewed in Vihinen et al Frontiers in Bioscience 5 : d917-928). Mice deficient in BTK
also have a reduced number of peripheral B cells and greatly decreased serum levels of IgM and IgG3. BTK deletion in mice has a profound effect on B cell proliferation induced by anti-IgM, and inhibits immune responses to thymus-independent type II antigens (Ellmeier et al, J Exp Med 192: 1611-1623 (2000)). BTK also plays a crucial role in mast cell activation through the high-affinity IgE
receptor (Fc_epsilon_RI). BTK deficient murine mast cells have reduced degranulation and decreased production of proinflammatory cytokines following Fe epsilon RI
cross-linking (Kawakami et al. Journal of Leukocyte Biology 65: 286-290).
[001871 BTK has been implicated in diabetes. BTK deficiency in non-obese diabetic mice dramatically protects against diabetes and improves B cell-related tolerance, as indicated by failure to generate autoantibodies to insulin (Kendall, et al. J. Immunol.
183: 6403-6412 (2009)).
Modulation of BTK and improvement of B cell-related tolerance can therefore be used in treatment of diabetes, particularly T cell-mediated autoimmune diabetes, e.g.
type I diabetes.
[001881 BTK is also implicated in various cancers. For example, BTK is upregulated in pancreatic cancer cells compared with normal pancreas cells, and BTK is also upregulated in chronic pancreatitis cells, which is sometimes a precursor to pancreatic cancer (Crnogorac-Jurcevic, et al. Gastroenterology 129: 1454-1463 (2005)). Due to the key role of BTK in regulation of B-cell development, activation, signaling, and survival, BTK is involved in many B
cell-related cancers.
[001891 Provided compounds are inhibitors of BTK and are therefore useful for treating one or more disorders associated with activity of BTK. Thus, in some embodiments, the present invention provides a method for treating a BTK-mediated disorder comprising the step of administering to a patient in need thereof a compound of the present invention, or pharmaceutically acceptable composition thereof.

diabetes), irritable bowel syndrome, Crohn's disease, lupus and renal transplant.
(d) ITK
[001991 Interleukin-2 inducible T-cell kinase ("ITK") is expressed in T cells, mast cells and natural killer cells. It is activated in T cells upon stimulation of the T
cell receptor (TCR), and in mast cells upon activation of the high affinity IgE receptor. Following receptor stimulation in T
cells, Lck, a Src tyrosine kinase family member, phosphorylates Y511 in the kinase domain activation loop of ITK (S. D. Heyeck et al., 1997, J. Biol. Chem, 272, 25401-25408). Activated ITK, together with Zap-70 is required for phosphorylation and activation of PLC-gamma (S. C.
Bunnell et al., 2000, J. Biol. Chem., 275, 2219-2230). PLC-gamma catalyzes the formation of inositol 1,4,5-triphosphate and diacylglycerol, leading to calcium mobilization and PKC
activation, respectively. These events activate numerous downstream pathways and lead ultimately to degranulation (mast cells) and cytokine gene expression (T
cells) (Y. Kawakami et al., 1999, J. Leukocyte Biol., 65, 286-290).
[002001 The role of ITK in T cell activation has been confirmed in ITK
knockout mice. CD4+
T cells from ITK knockout mice have a diminished proliferative response in a mixed lymphocyte reaction or upon Con A or anti-CD3 stimulation. (X. C. Liao and D. R. Littman, 1995, Immunity, 3, 757-769). Also, T cells from ITK knockout mice produced little IL-2 upon TCR stimulation resulting in reduced proliferation of these cells. In another study, ITK
deficient CD4+ T cells produced reduced levels of cytokines including IL-4, IL-5 and IL-13 upon stimulation of the TCR, even after priming with inducing conditions (D. J. Fowell, 1999, Immunity, 11, 399-409).
[002011 The role of ITK in PLC-gamma activation and in calcium mobilization was also confirmed in the T cells of these knockout mice, which had severely impaired IP3 generation and no extracellular calcium influx upon TCR stimulation (K. Liu et al., 1998, J.
Exp. Med. 187, 1721-1727). Such studies support a key role for ITK in activation of T cells and mast cells. Thus an inhibitor of ITK would be of therapeutic benefit in diseases mediated by inappropriate activation of these cells.
[002021 It has been well established that T cells play an important role in regulating the immune response (Powrie and Coffinan, 1993, Immunology Today, 14, 270-274).
Indeed, activation of T cells is often the initiating event in immunological disorders. Following activation of the TCR, there is an influx of calcium that is required for T cell activation. Upon activation, T
cells produce cytokines, including IL-2, 4, 5, 9, 10, and 13 leading to T cell proliferation, differentiation, and effector function. Clinical studies with inhibitors of IL-2 have shown that interference with T cell activation and proliferation effectively suppresses immune response in vivo (Waldmann, 1993, Immunology Today, 14, 264-270). Accordingly, agents that inhibit T
lymphocyte activation and subsequent cytokine production, are therapeutically useful for selectively suppressing the immune response in a patient in need of such immunosuppression.
[002031 Mast cells play a critical roll in asthma and allergic disorders by releasing pro-inflammatory mediators and cytokines. Antigen-mediated aggregation of Fc.epsilon.Rl, the high-affinity receptor for IgE, results in activation of mast cells (D. B. Corry et al., 1999, Nature, 402, B 18-23). This triggers a series of signaling events resulting in the release of mediators, including histamine, proteases, leukotrienes and cytokines (J. R. Gordon et al., 1990, Immunology Today, 11, 458-464.) These mediators cause increased vascular permeability, mucus production, bronchoconstriction, tissue degradation and inflammation thus playing key roles in the etiology and symptoms of asthma and allergic disorders.
[002041 Published data using ITK knockout mice suggests that in the absence of ITK function, increased numbers of memory T cells are generated (A. T. Miller et al., 2002 The Journal of Immunology, 168, 2163-2172). One strategy to improve vaccination methods is to increase the number of memory T cells generated (S. M. Kaech et al., Nature Reviews Immunology, 2, 251-262). In addition, deletion of ITK in mice results in reduced T cell receptor (TCR)-induced proliferation and secretion of the cytokines IL-2, IL-4, IL-5, IL-10 and IFN-y (Schaeffer et al, Science 284; 638-641 (1999) ), Fowell et al, Immunity 11, 399-409 (1999), Schaeffer et al, Nature Immunology 2 (12): 1183-1188 (2001) )). The immunological symptoms of allergic asthma are attenuated in ITK-/-mice. Lung inflammation, eosinophil infiltration and mucus production are drastically reduced in ITK-/-mice in response to challenge with the allergen OVA
(Mueller et al, Journal of Immunology 170: 5056-5063 (2003)). ITK has also been implicated in atopic dermatitis. This gene has been reported to be more highly expressed in peripheral blood T
cells from patients with moderate and/or severe atopic dermatitis than in controls or patients with mild atopic dermatitis (Matsumoto et at, International Archives of Allergy and Immunology 129:
327-340 (2002)).
[00205] Splenocytes from RLK-/-mice secrete half the IL-2 produced by wild type animals in response to TCR engagement (Schaeffer et at, Science 284: 638-641 (1999)), while combined deletion of ITK and RLK in mice leads to a profound inhibition of TCR-induced responses including proliferation and production of the cytokines IL-2, IL-4, IL-5 and IFN-y (Schaeffer et at, Nature Immunology 2 (12): 1183-1188 (2001), Schaeffer et at, Science 284:
638-641 (1999)).
Intracellular signalling following TCR engagement is effected in ITK/RLK
deficient T cells;
inositol triphosphate production, calcium mobilization, MAP kinase activation, and activation of the transcription factors NFAT and AP-1 are all reduced (Schaeffer et at, Science 284: 638-641 (1999), Schaeffer et at, Nature Immunology 2 (12): 1183-1188 (2001)).
[00206] Provided compounds are inhibitors of ITK and are therefore useful for treating one or more disorders associated with activity of ITK. Thus, in some embodiments, the present invention provides a method for treating an ITK-mediated disorder comprising the step of administering to a patient in need thereof a compound of the present invention, or pharmaceutically acceptable composition thereof.
[00207] As used herein, the term "ITK-mediated" disorders or conditions as used herein means any disease or other deleterious condition in which ITK, or a mutant thereof, is known to play a role. Accordingly, another embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which ITK, or a mutant thereof, is known to play a role. Specifically, the present invention relates to a method of treating or lessening the severity of a disease or condition selected from a mast cell-mediated condition, a basophil-mediated disorder, an immune or allergic disorder, wherein said method comprises administering to a patient in need thereof a compound or composition according to the present invention.
[00208] In some embodiments, the present invention provides a method for treating or lessening the severity of one or more diseases and conditions associated with ITK, wherein the disease or condition is an immune disorder, including inflammatory diseases, autoimmune diseases, organ and bone marrow transplant rejection and other disorders associated with T cell-mediated immune response or mast cell-mediated immune response.
[00209] In certain embodiments, the present invention provides a method for treating or lessening the severity of one or more diseases and conditions associated with ITK, wherein the disease or condition is acute or chronic inflammation, an allergy, contact dermatitis, psoriasis, rheumatoid arthritis, multiple sclerosis, diabetes (e.g. type 1 diabetes), inflammatory bowel disease, Guillain-Barre syndrome, Crohn's disease, ulcerative colitis, cancer, graft versus host disease (and other forms of organ or bone marrow transplant rejection) or lupus erythematosus.
[00210] In certain embodiments, the present invention provides a method for treating or lessening the severity of one or more diseases and conditions associated with ITK, wherein the disease or condition is a mast cell driven conditions, a basophil-mediated disorder, reversible obstructive airway disease, asthma, rhinitis, chronic obstructive pulmonary disease (COPD), peripheral T-cell lymphomas or HIV [also known as Acquired Immunodeficiency Syndrome (AIDS)]. Such conditions include those described in Readinger, et al., PNAS
105: 6684-6689 (2008).
(e) JAK Family [002111 The Janus kinases (JAK) are a family of tyrosine kinases consisting of JAK1, JAK2, JAK3 and TYK2. The JAKs play a critical role in cytokine signaling. The down-stream substrates of the JAK family of kinases include the signal transducer and activator of transcription (STAT) proteins. JAK/STAT signaling has been implicated in the mediation of many abnormal immune responses such as allergies, asthma, autoimmune diseases such as transplant rejection, rheumatoid arthritis, amyotrophic lateral sclerosis and multiple sclerosis as well as in solid and hematologic malignancies such as leukemias and lymphomas.
The pharmaceutical intervention in the JAK/STAT pathway has been reviewed [Frank, Mot. Med. 5 432-456 (1999) & Seidel, et al, Oncogene 19 : 2645-2656 (2000)].
[00212] JAK1, JAK2, and TYK2 are ubiquitously expressed, while JAK3 is predominantly expressed in hematopoietic cells. JAK3 binds exclusively to the common cytokine receptor gamma chain (yc) and is activated by IL-2, IL-4, IL-7, IL-9, and IL-15.
[00213] The proliferation and survival of murine mast cells induced by IL-4 and IL-9 have, in fact, been shown to be dependent on JAK3-and yc-signaling [Suzuki et al, Blood 96 : 2172-2180 (2000) ].
[00214] Cross-linking of the high-affinity immunoglobulin (Ig) E receptors of sensitized mast cells leads to a release of proinflammatory mediators, including a number of vasoactive cytokines resulting in acute allergic, or immediate (type I) hypersensitivity reactions [Gordon et al, Nature 346 : 274-276 (1990) & Galli, N. Engl. J. Med., 328 : 257- 265 (1993) ]. A crucial role for JAK3 in IgE receptor-mediated mast cell responses in vitro and in vivo has been established [Malaviya, et al, Biochem. Biophys. Res. Commun. 257 : 807-813 (1999) ]. In addition, the prevention of type I hypersensitivity reactions, including anaphylaxis, mediated by mast cell-activation through inhibition of JAK3 has also been reported [Malaviya et al, J. Biol.
Chem. 274 : 27028-27038 (1999) ]. Targeting mast cells with JAK3 inhibitors modulated mast cell degranulation in vitro and prevented IgE receptor/antigen-mediated anaphylactic reactions in vivo.
[00215] A recent study described the successful targeting of JAK3 for immune suppression and allograft acceptance. The study demonstrated a dose-dependent survival of buffalo heart allograft in Wistar Furth recipients upon administration of inhibitors of JAK3 indicating the possibility of regulating unwanted immune responses in graft versus host disease [Kirken, Transpl. Proc. 33: 3268-3270 (2001)].
[00216] IL-4-mediated STAT-phosphorylation has been implicated as the mechanism involved in early and late stages of rheumatoid arthritis (RA). Up-regulation of proinflammatory cytokines in RA synovium and synovial fluid is a characteristic of the disease. It has been demostrated that IL-4-mediated activation of IL-4/STAT pathway is mediated through the Janus kinases (JAK 1 & 3) and that IL-4-associated JAK kinases are expressed in the RA synovium [Muller-Ladner, et al, J. Immunol. 164: 3894-3901 (2000)].
[00217] Familial amyotrophic lateral sclerosis (FALS) is a fatal neurodegenerative disorder affecting about 10% of ALS patients. The survival rates of FALS mice were increased upon treatment with a JAK3 specific inhibitor. This confirmed that JAK3 plays a role in FALS [Trieu, et al, Biochem. Biophys. Res. Commun. 267: 22-25 (2000)].
[00218] Signal transducer and activator of transcription (STAT) proteins are activated by, among others, the JAK family kinases. Results form a recent study suggested the possibility of intervention in the JAK/STAT signaling pathway by targeting JAK family kinases with specific inhibitors for the treatment of leukemia [Sudbeck, et al., Clin. Cancer Res. 5 : 1569-1582 (1999) ]. JAK3 specific compounds were shown to inhibit the clonogenic growth of JAK3-expressing cell lines DAUDI, RAMOS, LC1 ; 19, NALM-6, MOLT-3 and HL-60. Inhibition of JAK3 and TYK 2 abrogated tyrosine phosphorylation of STAT3, and inhibited cell growth of mycosis fungoides, a form of cutaneous T cell lymphoma.
[002191 JAK3 has also been implicated in diabetes. A JAK3 inhibitor exhibited potent immunomodulatory activity and delayed the onset of diabetes in the NOD mouse model of autoimmune type 1 diabetes (Cetkovic-Cvrlje, et al. Clin. Immunol. 106: 213-225 (2003)).
[002201 According to another embodiment, the invention provides a method for treating or lessening the severity of a JAK3-mediated disease or condition in a patient comprising the step of administering to said patient a composition according to the present invention.
[002211 The term "JAK3-mediated disease", as used herein means any disease or other deleterious condition in which a JAK3 kinase is known to play a role.
Accordingly, another embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which JAK3 is known to play a role. Specifically, the present invention relates to a method of treating or lessening the severity of a disease or condition selected from immune responses such as allergic or type I hypersensitivity reactions, asthma, autoimmune diseases such as transplant rejection, graft versus host disease, rheumatoid arthritis, diabetes (e.g. type I
diabetes), amyotrophic lateral sclerosis, and multiple sclerosis, neurodegenerative disorders such as familial amyotrophic lateral sclerosis (FALS), as well as in solid and hematologic malignancies such as leukemias and lymphomas, wherein said method comprises administering to a patient in need thereof a composition according to the present invention.
[002221 The compounds and compositions, according to the method of the present invention, may be administered using any amount and any route of administration effective for treating or lessening the severity of cancer, an autoimmune disorder, a neurodegenerative or neurological disorder, schizophrenia, a bone-related disorder, liver disease, or a cardiac disorder. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the particular agent, its mode of administration, and the like. Compounds of the invention are preferably formulated in dosage unit form for ease of administration and uniformity of dosage. The expression "dosage unit form" as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts.
The term "patient", as used herein, means an animal, preferably a mammal, and most preferably a human.
[002231 Pharmaceutically acceptable compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the infection being treated.
In certain embodiments, the compounds of the invention may be administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect.
[002241 Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.
[002251 Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
[00226] Injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
[00227] In order to prolong the effect of a compound of the present invention, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection.
This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form.
Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled.
Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues.
[00228] Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.
[00229] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar--agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, 0 absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.
[002301 Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner.
Examples of embedding compositions that can be used include polymeric substances and waxes.
Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.
[002311 The active compounds can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art.
In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner.
Examples of embedding compositions that can be used include polymeric substances and waxes.
[002321 Dosage forms for topical or transdermal administration of a compound of this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required.
Ophthalmic formulation, ear drops, and eye drops are also contemplated as being within the scope of this invention. Additionally, the present invention contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body.
Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

[0027] As described herein, compounds of the invention may contain "optionally substituted" moieties. In general, the term "substituted", whether preceded by the term "optionally" or not, means that one or more hydrogens of the designated moiety are replaced with a suitable substituent. Unless otherwise indicated, an "optionally substituted" group may have a suitable substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position.
Combinations of substituents envisioned by this invention are preferably those that result in the formation of stable or chemically feasible compounds. The term "stable", as used herein, refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and, in certain embodiments, their recovery, purification, and use for one or more of the purposes disclosed herein.

[00341 As used herein, the term "pharmaceutically acceptable salt" refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio.
Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange.
Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like.
[00351 Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N+(Cl 4alkyl)4 salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate.
[00361 Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S configurations for each asymmetric center, Z and E double bond isomers, and Z and E conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention.
Additionally, unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. For example, compounds having the present structures including the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a 13C- or 14C-enriched carbon are within the scope of this invention.
Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present invention. In some embodiments, the Rl group of formula I-a and I-b comprises one or more deuterium atoms.
[00371 As used herein, the term "irreversible" or "irreversible inhibitor"
refers to an inhibitor (i.e. a compound) that is able to be covalently bonded to a target protein kinase in a substantially non-reversible manner. That is, whereas a reversible inhibitor is able to bind to (but is generally unable to form a covalent bond) the target protein kinase, and therefore can become dissociated from the target protein kinase, an irreversible inhibitor will remain substantially bound to the target protein kinase once covalent bond formation has occurred. Irreversible inhibitors usually display time dependency, whereby the degree of inhibition increases with the time with which the inhibitor is in contact with the enzyme. Methods for identifying if a compound is acting as an irreversible inhibitor are known to one of ordinary skill in the art. Such methods include, but are not limited to, enzyme kinetic analysis of the inhibition profile of the compound with the protein kinase target, the use of mass spectrometry of the protein drug target modified in the presence of the inhibitor compound, discontinuous exposure, also known as "washout,"
experiments, and the use of labeling, such as radiolabelled inhibitor, to show covalent modification of the enzyme, as well as other methods known to one of skill in the art.
[00381 One of ordinary skill in the art will recognize that certain reactive functional groups can act as "warheads." As used herein, the term "warhead" or "warhead group"
refers to a functional group present on a compound of the present invention wherein that functional group is capable of covalently binding to an amino acid residue (such as cysteine, lysine, histidine, or other residues capable of being covalently modified) present in the binding pocket of the target protein, thereby irreversibly inhibiting the protein. It will be appreciated that the -L-Y group, as defined and described herein, provides such warhead groups for covalently, and irreversibly, inhibiting the protein.
[00391 As used herein, the term "inhibitor" is defined as a compound that binds to and /or inhibits the target protein kinase with measurable affinity. In certain embodiments, an inhibitor has an IC50 and/or binding constant of less about 50 M, less than about 1 M, less than about 500 nM, less than about 100 nM, or less than about 10 nM, [00401 The terms "measurable affinity" and "measurably inhibit," as used herein, means a measurable change in at least one of ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3 activity between a sample comprising a compound of the present invention, or composition thereof, and at least one of ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, and an equivalent sample comprising at least one of ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, in the absence of said compound, or composition thereof.

[00111] As defined generally above, R' is a warhead group, or, when R' and Rx form a ring, then -Q-Z is a warhead group. Without wishing to be bound by any particular theory, it is believed that such R' groups, i.e. warhead groups, are particularly suitable for covalently binding to a key cysteine residue in the binding domain of certain protein kinases.
Protein kinases having a cysteine residue in the binding domain are known to one of ordinary skill in the art and include ErbBI, ErbB2, and ErbB4, or a mutant thereof. In certain embodiments, compounds of the present invention have a warhead group characterized in that inventive compounds target one or more of the following cysteine residues:
[00112] Thus, in some embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue thereby irreversibly inhibiting the enzyme. In certain embodiments, the cysteine residue is Cys797 of ErbB 1, Cys805 of ErbB2 and Cys803 of ErbB4, or a mutant thereof, where the provided residue numbering is in accordance with Uniprot (code P00533 for ErbBl; code P04626 for ErbB2, and Q15303 for ErbB4). It will be understood that the Cys of ErbB 1 (EGFR) is variably called 773 or 797 depending on whether the parent sequence contains the signal peptide or not. Thus, in accordance with the present invention, the relevant cysteine residue of ErbB 1 may be described as Cys 773 or Cys 797 and these terms are used interchangeably.
[00113] One of ordinary skill in the art will recognize that a variety of warhead groups, as defined herein, are suitable for such covalent bonding. Such R' groups include, but are not limited to, those described herein and depicted in Table 4, infra.
[00114] As depicted in formulae I-a and I-b supra, the R' warhead group can be in an ortho-, meta-, or para-position. In certain embodiments, the R' warhead group is in a meta-position of the phenyl ring relative to the rest of the molecule.
[00115] In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of TEC, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 449.
[001161 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of BTK, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 481.
[001171 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of ITK, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 442.
[001181 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of BMX, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 496.
[001191 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of JAK3, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 909.
[001201 In certain embodiments, R' is characterized in that the -L-Y moiety is capable of covalently binding to a cysteine residue of TXK, thereby irreversibly inhibiting the enzyme. In some embodiments, the cysteine residue is Cys 350.
[001211 One of ordinary skill in the art will recognize that a variety of warhead groups, as defined herein, are suitable for such covalent bonding. Such R' groups include, but are not limited to, those described herein and depicted in Table 3, infra.

4. Uses, Formulation and Administration Pharmaceutically Acceptable Compositions [001261 According to another embodiment, the invention provides a composition comprising a compound of this invention or a pharmaceutically acceptable derivative thereof and a pharmaceutically acceptable carrier, adjuvant, or vehicle. The amount of compound in compositions of this invention is such that is effective to measurably inhibit a protein kinase, particularly at least one of ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof, in a biological sample or in a patient. In certain embodiments, the amount of compound in compositions of this invention is such that is effective to measurably inhibit at least one of ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof, in a biological sample or in a patient. In certain embodiments, a composition of this invention is formulated for administration to a patient in need of such composition. In some embodiments, a composition of this invention is formulated for oral administration to a patient.
[001271 The term "patient", as used herein, means an animal, preferably a mammal, and most preferably a human.
[001281 The term "pharmaceutically acceptable carrier, adjuvant, or vehicle"
refers to a non-toxic carrier, adjuvant, or vehicle that does not destroy the pharmacological activity of the compound with which it is formulated. Pharmaceutically acceptable carriers, adjuvants or vehicles that may be used in the compositions of this invention include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat.
[001291 A "pharmaceutically acceptable derivative" means any non-toxic salt, ester, salt of an ester or other derivative of a compound of this invention that, upon administration to a recipient, is capable of providing, either directly or indirectly, a compound of this invention or an inhibitorily active metabolite or residue thereof.
[001301 As used herein, the term "inhibitorily active metabolite or residue thereof' means that a metabolite or residue thereof is also an inhibitor of at least one of ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof.
[001311 Compositions of the present invention may be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir.
The term "parenteral" as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques. Preferably, the compositions are administered orally, intraperitoneally or intravenously. Sterile injectable forms of the compositions of this invention may be aqueous or oleaginous suspension. These suspensions may be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents.
The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol.
Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium.
[001321 For this purpose, any bland fixed oil may be employed including synthetic mono- or di-glycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, such as carboxymethyl cellulose or similar dispersing agents that are commonly used in the formulation of pharmaceutically acceptable dosage forms including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation.
[001331 Pharmaceutically acceptable compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, aqueous suspensions or solutions. In the case of tablets for oral use, carriers commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried cornstarch. When aqueous suspensions are required for oral use, the active ingredient is combined with emulsifying and suspending agents. If desired, certain sweetening, flavoring or coloring agents may also be added.
[001341 Alternatively, pharmaceutically acceptable compositions of this invention may be administered in the form of suppositories for rectal administration. These can be prepared by mixing the agent with a suitable non-irritating excipient that is solid at room temperature but liquid at rectal temperature and therefore will melt in the rectum to release the drug. Such materials include cocoa butter, beeswax and polyethylene glycols.
[001351 Pharmaceutically acceptable compositions of this invention may also be administered topically, especially when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, the skin, or the lower intestinal tract. Suitable topical formulations are readily prepared for each of these areas or organs.
[001361 Topical application for the lower intestinal tract can be effected in a rectal suppository formulation (see above) or in a suitable enema formulation.
Topically-transdermal patches may also be used.
[001371 For topical applications, provided pharmaceutically acceptable compositions may be formulated in a suitable ointment containing the active component suspended or dissolved in one or more carriers. Carriers for topical administration of compounds of this invention include, but are not limited to, mineral oil, liquid petrolatum, white petrolatum, propylene glycol, polyoxyethylene, polyoxypropylene compound, emulsifying wax and water.
Alternatively, provided pharmaceutically acceptable compositions can be formulated in a suitable lotion or cream containing the active components suspended or dissolved in one or more pharmaceutically acceptable carriers. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water.
[001381 For ophthalmic use, provided pharmaceutically acceptable compositions may be formulated as micronized suspensions in isotonic, pH adjusted sterile saline, or, preferably, as solutions in isotonic, pH adjusted sterile saline, either with or without a preservative such as benzylalkonium chloride. Alternatively, for ophthalmic uses, the pharmaceutically acceptable compositions may be formulated in an ointment such as petrolatum.
[001391 Pharmaceutically acceptable compositions of this invention may also be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other conventional solubilizing or dispersing agents.
[001401 Most preferably, pharmaceutically acceptable compositions of this invention are formulated for oral administration.
[001411 The amount of compounds of the present invention that may be combined with the carrier materials to produce a composition in a single dosage form will vary depending upon the host treated, the particular mode of administration. Preferably, provided compositions should be formulated so that a dosage of between 0.01 - 100 mg/kg body weight/day of the inhibitor can be administered to a patient receiving these compositions.
[001421 It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease being treated. The amount of a compound of the present invention in the composition will also depend upon the particular compound in the composition.
Uses of Compounds and Pharmaceutically Acceptable Compositions [001431 Compounds and compositions described herein are generally useful for the inhibition of protein kinase activity of one or more enzymes.
[001441 Drug resistance is emerging as a significant challenge for targeted therapies. For example, drug resistance has been reported for Gleevec and Iressa , as well as several other kinase inhibitors in development. In addition, drug resistance has been reported for the cKit and PDGFR receptors. It has been reported that irreversible inhibitors may be effective against drug resistant forms of protein kinases (Kwak, E. L., R. Sordella, et al. (2005).
"Irreversible inhibitors of the EGF receptor may circumvent acquired resistance to gefitinib." PNAS
102(21): 7665-7670.) Without wishing to be bound by any particular theory, it is believed that compounds of the present invention may be effective inhibitors of drug resistant forms of protein kinases.
[001451 As used herein, the term "clinical drug resistance" refers to the loss of susceptibility of a drug target to drug treatment as a consequence of mutations in the drug target.
[001461 As used herein, the term "resistance" refers to changes in the wild-type nucleic acid sequence coding a target protein, and/or the protein sequence of the target, which changes decrease or abolish the inhibitory effect of the inhibitor on the target protein.
[001471 Examples of kinases that are inhibited by the compounds and compositions described herein and against which the methods described herein are useful include ErbB
1, ErbB2, ErbB3, ErbB4, a TEC-kinase (including BTK, ITK, TEC, BMX and RLK), and/or JAK3, or a mutant thereof.
[001481 The activity of a compound utilized in this invention as an inhibitor of ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof, may be assayed in vitro, in vivo or in a cell line. In vitro assays include assays that determine inhibition of either the phosphorylation activity and/or the subsequent functional consequences, or ATPase activity of activated ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof.
Alternate in vitro assays quantitate the ability of the inhibitor to bind to ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3. Inhibitor binding may be measured by radiolabeling the inhibitor prior to binding, isolating the inhibitor/ErbB1, inhibitor/ErbB2, inhibitor/ErbB3, inhibitor/ErbB4, inhibitor/TEC-kinase (i.e., TEC, BTK, ITK, RLK and BMX), or inhibitor/JAK3 complex and determining the amount of radiolabel bound. Alternatively, inhibitor binding may be determined by running a competition experiment where new inhibitors are incubated with ErbBl, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3 bound to known radioligands.
Detailed conditions for assaying a compound utilized in this invention as an inhibitor of ErbB 1, ErbB2, ErbB3, ErbB4, a TEC-kinase, and/or JAK3, or a mutant thereof, are set forth in the Examples below.
[001491 Protein tyrosine kinases are a class of enzymes that catalyze the transfer of a phosphate group from ATP or GTP to a tyrosine residue located on a protein substrate. Receptor tyrosine kinases act to transmit signals from the outside of a cell to the inside by activating secondary messaging effectors via a phosphorylation event. A variety of cellular processes are promoted by these signals, including proliferation, carbohydrate utilization, protein synthesis, angiogenesis, cell growth, and cell survival.
(a) ErbB Family [001501 ErbB receptors, a major family of receptor tyrosine kinases, are composed of an extracellular ligand binding domain, a single transmembrane domain, and an intracellular domain with tyrosine kinase activity. The ErbB family comprises ErbBI
(commonly known as EGFR), ErbB2 (commonly known as HER2 or neu), ErbB3 (commonly known as HER3), and ErbB4 (commonly known as HER4). More than 10 ligands (including EGF, TGFa, AR, BTC, EPR, HB-EGF, NRG-l, NRG-2, NRG-3, NRG-4) have been identified for the various receptor family members. Upon ligand binding the extracellular domain undergoes conformational change, allowing the formation of homodimers or heterodimers with other members of the ErbB
family. Dimerization induces tyrosine phosphorylation of specific residues in the intracellular domain that serve as docking sites for adaptor proteins and downstream effectors. In some contexts, activation of phosphatidyl-inositol 3-kinase (P13K) and mitogen-activated protein kinase pathways occur, leading to cell proliferation and survival (Lin, N. U.;
Winer, E. P., Breast Cancer Res 6: 204-210, 2004).
[001511 Interaction between family members is necessitated by deficiencies in ErbB2, which has no known ligand, and ErbB3, which is kinase dead. EGFR, ErbB3, and ErbB4 bind ligand to induce ErbB receptor homodimerization or heterodimerization, whereas ErbB2 functions as the preferred dimerization partner. The composition of the pairwise combinations is important for signal diversification, as dimer identity determines which downstream pathways are activated.
Representative downstream gene products in the ErbB signal transduction pathway include She, Grb2, SOS I, Ras, Rafl, Mek, ERK1, ERK2, ERa, Akt, mTOR, FKHR, p27, Cyclin Dl, FasL, GSK-3, Bad, and STAT3.
[001521 There is strong precedent for involvement of the EGFR and other members of the ErbB family in human cancer because over 60% of all solid tumors overexpress at least one of these proteins or their ligands. Constitutively active, tumorigenic EGFR All, a mutant possessing a truncated extracellular domain, has been reported to be present in up to 78% of breast carcinomas and has also been found in glioblastomas. Overexpression of EGFR is commonly found in breast, lung, head and neck, bladder tumors, while ErbB2 expression is frequently elevated in human tumors of epithelial origin. Activating mutations in the tyrosine kinase domain have been identified in patients with non-small cell lung cancer (Lin, N. U.;
Winer, E. P., Breast Cancer Res 6: 204-210, 2004). ErbB l and/or ErbB2 amplification has also been implicated in squamous cell carcinomas, salivary gland carcinomas, ovarian carcinomas, and pancreatic cancers (Cooper, G.C. Oncogenes. 2nd ed. Sudbury: Jones and Barlett, 1995;
Zhang, Y., et al., Cancer Res 66 : 1025-32, 2006). Overexpression of ErbB2 has potent transforming activity, likely due to its ability to cooperate with other ErbB
receptors (Sherman, L., et al., Oncogene 18: 6692-99, 1999). In fact, some human cancers that overexpress both EGFR and ErbB2 have a poorer prognosis than cancers that overexpress either receptor alone.
[001531 The ErbB signaling network is often a key component in the pathogenesis of breast cancer. Amplification of ErbB2 is associated with an aggressive tumor phenotype that is characterized by relatively rapid tumor growth, metastatic spread to visceral sites, and drug resistance. ErbB2 has been shown to be amplified in 20% of axillary node-negative ("ANN") breast cancer cases, and this amplification has been identified as an independent prognostic factor for risk of recurrence in ANN breast cancer. (Andrulis, I.L., et al., J
Clin Oncol 16: 1340-9, 1998).
[001541 Targeted blockade of ErbB signaling with trastuzumab (Herceptin), a monoclonal antibody directed at ErbB2, has been shown to improve survival in women with ErbB2-positive, advanced breast cancer. Other monoclonal antibodies directed against ErbB
receptors include cetuximab (Erbitux) and panitumumab (Vectibix).
[001551 Several small molecule tyrosine kinase inhibitors (TKIs) have been found to act selectively upon ErbB family members. Notable examples include gefitinib (Iressa) and erlotinib (Tarceva), both of which target the EGFR. These small molecules compete with ATP
for binding to the kinase domain of the receptor. Compared to monoclonal antibodies, TKIs have several advantages in that they are orally bioavailable, well-tolerated, and appear to be active against truncated forms of ErbB2 and EGFR receptors (e.g., EGFR vlll) in vitro. In addition, the small size of small molecule TKIs may allow them to penetrate sanctuary sites such as the central nervous system. Finally, the homology between kinase domains of ErbB receptors allows for development of TKIs that target more than one member of the ErbB
family simultaneously, the advantages of which are described herein.
[00156] Although certain malignancies have been linked to the overexpression of individual receptors, efficient signal transduction relies on the coexpression of ErbB
receptor family members. This cooperation of ErbB receptor family members in signal transduction and malignant transformation may limit the success of agents that target individual receptors in the treatment of cancer; a potential mechanism of resistance to agents targeting a single ErbB
receptor is upregulation of other members of the receptor family (Britten, C.
D., Mol Cancer Ther 3: 1335-42, 2004).
[00157] Agents that target two or more ErbB receptors are called pan-ErbB
regulators. ERRP
is a pan-ErbB negative regulator that is expressed in most benign pancreatic ductal epithelium and islet cells. Tumors have been found to experience a progressive loss in ERRP expression.
That Erbitux and Herceptin show success in a limited patient base (tumors having increased expression of EGFR or ErbB2) could be partly due to coexpression of multiple ErbB family members.
[00158] In both in vitro and in vivo models, strategies that employ a dual ErbB approach seem to have greater antitumor activity than agents targeting a single ErbB
receptor. Thus, agents that target multiple members of ErbB family are likely to provide therapeutic benefit to a broader patient population (Zhang, Y., et al., Cancer Res 66: 1025-32, 2006). In certain embodiments, provided compounds inhibit one or more of ErbBl, ErbB2, ErbB3, and ErbB4. In some embodiments, provided compounds inhibit two or more of ErbB 1, ErbB2, ErbB3, and ErbB4, or a mutant thereof, and are therefore pan-ErbB inhibitors.
[00159] Clearly, there is growing evidence to support the concurrent inhibition of two or more ErbB (i.e., pan-ErbB) receptors in cancer therapy. Possible pan-ErbB
approaches with small molecules include using combinations of agents that target individual ErbB
receptors, using single agents that target multiple ErbB receptors, or using agents that interfere with ErbB
receptor interactions (e.g., dimerization). Additional strategies include therapies utilizing a small molecule in combination with antibodies, or chemoprevention therapies (Lin, N.
U.; Winer, E.
P., Breast Cancer Res 6: 204-210, 2004).
[00160] An example of small molecule pan-ErbB inhibition is CI-1033, an irreversible pan-ErbB inhibitor that covalently binds to the ATP binding site of the intracellular kinase domain.
Another irreversible pan-ErbB receptor tyrosine kinase inhibitor is HKI-272, which inhibits the growth of tumor cells that express ErbB-1 (EGFR) and ErbB-2 (HER-2) in culture and xenografts, and has antitumor activity in HER-2-positive breast cancer (Andrulis, I.L., et al., J
Clin Oncol 16: 1340-9, 1998). Irreversible inhibitors have demonstrated superior antitumor activity in comparison with reversible inhibitors.
[001611 Neurofibromatosis type I (NFI) is a dominantly inherited human disease affecting one in 2500-3500 individuals. Several organ systems are affected, including bones, skin, iris, and the central nervous system, as manifested in learning disabilities and gliomas. A hallmark of NF I is the development of benign tumors of the peripheral nervous system (neurofibromas), which vary greatly in both number and size among patients. Neurofibromas are heterogeneous tumors composed of Schwann cells, neurons, fibroblasts and other cells, w/
Schwann cells being the major (60-80%) cell type.
[001621 Abberant expression of the EGFR is associated with tumor development in NF 1 and in animal models of NFl, suggesting a role in pathogenesis and representing a novel potential therapeutic target. EGFR expression affects the growth of tumor cell lines derived from NF1 patients under conditions where EGF is not the primary factor driving growth of the cells. These data suggest that EGFR may play an important role in NFl tumorigenesis and Schwann cell transformation (DeClue, J. E., et al., J Clin Invest 105: 1233-41, 2000).
[001631 Patients with NFI develop aggressive Schwann cell neoplasmas known as malignant peripheral nerve sheath tumors (MPNSTs). Schwann cells are the major supportive cell population in the peripheral nervous system. Neoplastic Schwann cells within these neoplasms variably express the ErbB tyrosine kinases mediating NRG-l responses (ErbB2, ErbB3, ErbB4).
Neuregulin-1 (NRG-1) proteins promote the differentiation, survival, and/or proliferation of many cell types in the developing nervous system, and overexpression of NRG-1 in myelinating Schwann cells induces the formation of malignant peripheral nerve sheath tumors (MPNSTs) (Fallon, K. B., et al., J Neuro Oncol 66: 273-84, 2004).
[001641 Deregulation of Schwann cell growth is a primary defect driving the development of both benign neurofibromas and MPNST in neurofibromatosis type I (NF 1) patients. Growth of MPNSTs and transformed mouse Schwann cells in vitro is highly EGF-dependent and can be blocked by EGFR inhibitors under conditions where EGF is the primary growth factor. Some human MPNST cell lines have been found to demonstrate constitutive ErbB
phosphorylation.
While treatment with ErbB inhibitors abolishes ErbB phosphorylation and reduces DNA
synthesis in these lines, effective chemotherapeutic regimens for MPNST remain elusive (Stonecypher, M. S., et al., Oncogene 24: 5589-5605, 2005).
[001651 Schwannomas are peripheral nerve tumors comprised almost entirely of Schwann-like cells, and typically have mutations in the neurofibromatosis type II
(NF2) tumor suppressor gene. Ninety percent of NF2 patients develop bilateral vestibular schwannomas and/or spinal schwannomas. Enlarging schwannomas can compress adjacent structures, resulting in deafness and other neurologic problems. Surgical removal of these tumors is difficult, often resulting in increased patient morbidity.
[001661 Both normal human Schwann cells and schwannoma cells express neuregulin receptors (i.e., ErbB receptors), and schwannoma cells proliferate in response to neuregulin. It is possible that aberrant neuregulin production or response contributes to aberrant schwannoma cell proliferation (Pelton, P. D., et al., Oncogene 17: 2195-2209, 1998).
[001671 The NF2 tumor suppressor, Merlin, is a membrane/cytoskeleton-associated protein implicated in the regulation of tyrosine kinase activity. Genetic interactions between a Merlin mutation and EGFR pathway mutations have been documented in Drosophila (LaJeunesse, D.
R., et al., Genetics 158: 667-79, 2001). Other evidence suggests Merlin can inhibit EGFR
internalization and signaling upon cell-cell contact by restraining the EGFR
into a membrane compartment from which it can neither signal nor be internalized (McClatchey, A. I., et al., Genes and Development 19: 2265-77, 2005; Curto, M. C., et al., J Cell Biol 177: 893-903, 2007).
[001681 As used herein, the terms "treatment," "treat," and "treating" refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment may be administered after one or more symptoms have developed. In other embodiments, treatment may be administered in the absence of symptoms. For example, treatment may be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example to prevent or delay their recurrence.
[001691 Provided compounds are inhibitors of one or more of ErbBl, ErbB2, ErbB3, and ErbB4 and are therefore useful for treating one or more disorders associated with activity of one of more of ErbB 1, ErbB2, ErbB3, and ErbB4.

(b) TECFamily [001731 The TEC family of non-receptor tyrosine kinases, referred to herein as "TEC-kinases," plays a central role in signaling through antigen-receptors such as the TCR, BCR and Fc receptors (reviewed in Miller A, et al. Current Opinion in Immunology 14;
331-340 (2002).
TEC-kinases are essential for T cell activation. Three members of the family, Itk, Rlk and, are activated downstream of antigen receptor engagement in T cells and transmit signals to downstream effectors, including PLC-y. Combined deletion of Itk and Rlk in mice leads to a profound inhibition of TCR responses including proliferation, cytokine production and immune responses to an intracellular parasite (Toxoplasma gondii) (Schaeffer et al., Science 284; 638-641 (1999)). Intracellular signalling following TCR engagement is effected in ITK/RLK
deficient T cells; inositol triphosphate production, calcium mobilization and MAP kinase activation are all reduced. Tec-kinases are also essential for B cell development and activation.
[001741 TEC-kinases include five family members, which are expressed primarily in hematopoietic cells: TEC, BTK, ITK (also known as TSK and EMT), RLK (also known as TXK), and BMX (also known as ETK). Additional related TEC-kinases have been found in Drosophila melanogaster, zebrafish (Danio rerio), skate (Raja eglanteria), and sea urchin (Anthocidaris crassispina).
[001751 Provided compounds are inhibitors of one of more TEC-kinases and are therefore useful for treating one or more disorders associated with activity of one or more TEC-kinases.
Thus, in certain embodiments, the present invention provides a method for treating a TEC-mediated disorder comprising the step of administering to a patient in need thereof a compound of the present invention, or pharmaceutically acceptable composition thereof.
[001761 The term "TEC-mediated condition", as used herein means any disease or other deleterious condition in which TEC-kinases are known to play a role.

Accordingly, another embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which TEC-kinases are known to play a role. Specifically, the present invention relates to a method of treating or lessening the severity of a disease or condition selected from autoimmune, inflammatory, proliferative, and hyperproliferative diseases and immunologically-mediated diseases including rejection of transplanted organs or tissues and Acquired Immunodeficiency Syndrome (AIDS)(also known as HIV), wherein said method comprises administering to a patient in need thereof a composition of the present invention.

(c) Bruton's tyrosine kinase (BTK) [001841 Bruton's tyrosine kinase ("BTK"), a member of TEC-kinases, is a key signaling enzyme expressed in all hematopoietic cell types except T lymphocytes and natural killer cells.
BTK plays an essential role in the B-cell signaling pathway linking cell surface B-cell receptor (BCR) stimulation to downstream intracellular responses.
[001851 BTK is a key regulator of B-cell development, activation, signaling, and survival (Kurosaki, Curr Op Imm, 2000, 276-281; Schaeffer and Schwartzberg, Curr Op Imm 2000, 282-288). In addition, BTK plays a role in a number of other hematopoietic cell signaling pathways, e.g., Toll like receptor (TLR) and cytokine receptor-mediated TNF-a production in macrophages, IgE receptor (Fc_epsilonRI) signaling in mast cells, inhibition of Fas/APO-1 apoptotic signaling in B-lineage lymphoid cells, and collagen-stimulated platelet aggregation. See, e.g., C.
A. Jeffries, et al., (2003), Journal of Biological Chemistry 278:26258-26264;
N. J. Horwood, et al., (2003), The Journal of Experimental Medicine 197: 1603- 1611 ; Iwaki et al. (2005), Journal of Biological Chemistry 280(48):40261 -40270; Vassilev et al. (1999), Journal of Biological Chemistry 274(3): 1646-1656, and Quek et al. (1998), Current Biology 8(20):
1137-1140.
[001861 Patients with mutations in BTK have a profound block in B cell development, resulting in the almost complete absence of mature B lymphocytes and plasma cells, severely reduced Ig levels and a profound inhibition of Immoral response to recall antigens (reviewed in Vihinen et al Frontiers in Bioscience 5 : d917-928). Mice deficient in BTK
also have a reduced number of peripheral B cells and greatly decreased serum levels of IgM and IgG3. BTK deletion in mice has a profound effect on B cell proliferation induced by anti-IgM, and inhibits immune responses to thymus-independent type II antigens (Ellmeier et al, J Exp Med 192: 1611-1623 (2000)). BTK also plays a crucial role in mast cell activation through the high-affinity IgE
receptor (Fc_epsilon_RI). BTK deficient murine mast cells have reduced degranulation and decreased production of proinflammatory cytokines following Fe epsilon RI
cross-linking (Kawakami et al. Journal of Leukocyte Biology 65: 286-290).
[001871 BTK has been implicated in diabetes. BTK deficiency in non-obese diabetic mice dramatically protects against diabetes and improves B cell-related tolerance, as indicated by failure to generate autoantibodies to insulin (Kendall, et al. J. Immunol.
183: 6403-6412 (2009)).
Modulation of BTK and improvement of B cell-related tolerance can therefore be used in treatment of diabetes, particularly T cell-mediated autoimmune diabetes, e.g.
type I diabetes.
[001881 BTK is also implicated in various cancers. For example, BTK is upregulated in pancreatic cancer cells compared with normal pancreas cells, and BTK is also upregulated in chronic pancreatitis cells, which is sometimes a precursor to pancreatic cancer (Crnogorac-Jurcevic, et al. Gastroenterology 129: 1454-1463 (2005)). Due to the key role of BTK in regulation of B-cell development, activation, signaling, and survival, BTK is involved in many B
cell-related cancers.
[001891 Provided compounds are inhibitors of BTK and are therefore useful for treating one or more disorders associated with activity of BTK.

diabetes), irritable bowel syndrome, Crohn's disease, lupus and renal transplant.
(d) ITK
[001991 Interleukin-2 inducible T-cell kinase ("ITK") is expressed in T cells, mast cells and natural killer cells. It is activated in T cells upon stimulation of the T
cell receptor (TCR), and in mast cells upon activation of the high affinity IgE receptor. Following receptor stimulation in T
cells, Lck, a Src tyrosine kinase family member, phosphorylates Y511 in the kinase domain activation loop of ITK (S. D. Heyeck et al., 1997, J. Biol. Chem, 272, 25401-25408). Activated ITK, together with Zap-70 is required for phosphorylation and activation of PLC-gamma (S. C.
Bunnell et al., 2000, J. Biol. Chem., 275, 2219-2230). PLC-gamma catalyzes the formation of inositol 1,4,5-triphosphate and diacylglycerol, leading to calcium mobilization and PKC
activation, respectively. These events activate numerous downstream pathways and lead ultimately to degranulation (mast cells) and cytokine gene expression (T
cells) (Y. Kawakami et al., 1999, J. Leukocyte Biol., 65, 286-290).
[002001 The role of ITK in T cell activation has been confirmed in ITK
knockout mice. CD4+
T cells from ITK knockout mice have a diminished proliferative response in a mixed lymphocyte reaction or upon Con A or anti-CD3 stimulation. (X. C. Liao and D. R. Littman, 1995, Immunity, 3, 757-769). Also, T cells from ITK knockout mice produced little IL-2 upon TCR stimulation resulting in reduced proliferation of these cells. In another study, ITK
deficient CD4+ T cells produced reduced levels of cytokines including IL-4, IL-5 and IL-13 upon stimulation of the TCR, even after priming with inducing conditions (D. J. Fowell, 1999, Immunity, 11, 399-409).
[002011 The role of ITK in PLC-gamma activation and in calcium mobilization was also confirmed in the T cells of these knockout mice, which had severely impaired IP3 generation and no extracellular calcium influx upon TCR stimulation (K. Liu et al., 1998, J.
Exp. Med. 187, 1721-1727). Such studies support a key role for ITK in activation of T cells and mast cells. Thus an inhibitor of ITK would be of therapeutic benefit in diseases mediated by inappropriate activation of these cells.
[002021 It has been well established that T cells play an important role in regulating the immune response (Powrie and Coffinan, 1993, Immunology Today, 14, 270-274).
Indeed, activation of T cells is often the initiating event in immunological disorders. Following activation of the TCR, there is an influx of calcium that is required for T cell activation. Upon activation, T
cells produce cytokines, including IL-2, 4, 5, 9, 10, and 13 leading to T cell proliferation, differentiation, and effector function. Clinical studies with inhibitors of IL-2 have shown that interference with T cell activation and proliferation effectively suppresses immune response in vivo (Waldmann, 1993, Immunology Today, 14, 264-270). Accordingly, agents that inhibit T
lymphocyte activation and subsequent cytokine production, are therapeutically useful for selectively suppressing the immune response in a patient in need of such immunosuppression.
[002031 Mast cells play a critical roll in asthma and allergic disorders by releasing pro-inflammatory mediators and cytokines. Antigen-mediated aggregation of Fc.epsilon.Rl, the high-affinity receptor for IgE, results in activation of mast cells (D. B. Corry et al., 1999, Nature, 402, B 18-23). This triggers a series of signaling events resulting in the release of mediators, including histamine, proteases, leukotrienes and cytokines (J. R. Gordon et al., 1990, Immunology Today, 11, 458-464.) These mediators cause increased vascular permeability, mucus production, bronchoconstriction, tissue degradation and inflammation thus playing key roles in the etiology and symptoms of asthma and allergic disorders.
[002041 Published data using ITK knockout mice suggests that in the absence of ITK function, increased numbers of memory T cells are generated (A. T. Miller et al., 2002 The Journal of Immunology, 168, 2163-2172). One strategy to improve vaccination methods is to increase the number of memory T cells generated (S. M. Kaech et al., Nature Reviews Immunology, 2, 251-262). In addition, deletion of ITK in mice results in reduced T cell receptor (TCR)-induced proliferation and secretion of the cytokines IL-2, IL-4, IL-5, IL-10 and IFN-y (Schaeffer et al, Science 284; 638-641 (1999) ), Fowell et al, Immunity 11, 399-409 (1999), Schaeffer et al, Nature Immunology 2 (12): 1183-1188 (2001) )). The immunological symptoms of allergic asthma are attenuated in ITK-/-mice. Lung inflammation, eosinophil infiltration and mucus production are drastically reduced in ITK-/-mice in response to challenge with the allergen OVA
(Mueller et al, Journal of Immunology 170: 5056-5063 (2003)). ITK has also been implicated in atopic dermatitis. This gene has been reported to be more highly expressed in peripheral blood T
cells from patients with moderate and/or severe atopic dermatitis than in controls or patients with mild atopic dermatitis (Matsumoto et at, International Archives of Allergy and Immunology 129:
327-340 (2002)).
[00205] Splenocytes from RLK-/-mice secrete half the IL-2 produced by wild type animals in response to TCR engagement (Schaeffer et at, Science 284: 638-641 (1999)), while combined deletion of ITK and RLK in mice leads to a profound inhibition of TCR-induced responses including proliferation and production of the cytokines IL-2, IL-4, IL-5 and IFN-y (Schaeffer et at, Nature Immunology 2 (12): 1183-1188 (2001), Schaeffer et at, Science 284:
638-641 (1999)).
Intracellular signalling following TCR engagement is effected in ITK/RLK
deficient T cells;
inositol triphosphate production, calcium mobilization, MAP kinase activation, and activation of the transcription factors NFAT and AP-1 are all reduced (Schaeffer et at, Science 284: 638-641 (1999), Schaeffer et at, Nature Immunology 2 (12): 1183-1188 (2001)).
[00206] Provided compounds are inhibitors of ITK and are therefore useful for treating one or more disorders associated with activity of ITK. Thus, in some embodiments, the present invention provides a method for treating an ITK-mediated disorder comprising the step of administering to a patient in need thereof a compound of the present invention, or pharmaceutically acceptable composition thereof.
[00207] As used herein, the term "ITK-mediated" disorders or conditions as used herein means any disease or other deleterious condition in which ITK, or a mutant thereof, is known to play a role. Accordingly, another embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which ITK, or a mutant thereof, is known to play a role. Specifically, the present invention relates to a method of treating or lessening the severity of a disease or condition selected from a mast cell-mediated condition, a basophil-mediated disorder, an immune or allergic disorder, wherein said method comprises administering to a patient in need thereof a compound or composition according to the present invention.
[00208] In some embodiments, the present invention provides a method for treating or lessening the severity of one or more diseases and conditions associated with ITK, wherein the disease or condition is an immune disorder, including inflammatory diseases, autoimmune diseases, organ and bone marrow transplant rejection and other disorders associated with T cell-mediated immune response or mast cell-mediated immune response.
[00209] In certain embodiments, the present invention provides a method for treating or lessening the severity of one or more diseases and conditions associated with ITK, wherein the disease or condition is acute or chronic inflammation, an allergy, contact dermatitis, psoriasis, rheumatoid arthritis, multiple sclerosis, diabetes (e.g. type 1 diabetes), inflammatory bowel disease, Guillain-Barre syndrome, Crohn's disease, ulcerative colitis, cancer, graft versus host disease (and other forms of organ or bone marrow transplant rejection) or lupus erythematosus.
[00210] In certain embodiments, the present invention provides a method for treating or lessening the severity of one or more diseases and conditions associated with ITK, wherein the disease or condition is a mast cell driven conditions, a basophil-mediated disorder, reversible obstructive airway disease, asthma, rhinitis, chronic obstructive pulmonary disease (COPD), peripheral T-cell lymphomas or HIV [also known as Acquired Immunodeficiency Syndrome (AIDS)]. Such conditions include those described in Readinger, et al., PNAS
105: 6684-6689 (2008).
(e) JAK Family [002111 The Janus kinases (JAK) are a family of tyrosine kinases consisting of JAK1, JAK2, JAK3 and TYK2. The JAKs play a critical role in cytokine signaling. The down-stream substrates of the JAK family of kinases include the signal transducer and activator of transcription (STAT) proteins. JAK/STAT signaling has been implicated in the mediation of many abnormal immune responses such as allergies, asthma, autoimmune diseases such as transplant rejection, rheumatoid arthritis, amyotrophic lateral sclerosis and multiple sclerosis as well as in solid and hematologic malignancies such as leukemias and lymphomas.
The pharmaceutical intervention in the JAK/STAT pathway has been reviewed [Frank, Mot. Med. 5 432-456 (1999) & Seidel, et al, Oncogene 19 : 2645-2656 (2000)].
[00212] JAK1, JAK2, and TYK2 are ubiquitously expressed, while JAK3 is predominantly expressed in hematopoietic cells. JAK3 binds exclusively to the common cytokine receptor gamma chain (yc) and is activated by IL-2, IL-4, IL-7, IL-9, and IL-15.
[00213] The proliferation and survival of murine mast cells induced by IL-4 and IL-9 have, in fact, been shown to be dependent on JAK3-and yc-signaling [Suzuki et al, Blood 96 : 2172-2180 (2000) ].
[00214] Cross-linking of the high-affinity immunoglobulin (Ig) E receptors of sensitized mast cells leads to a release of proinflammatory mediators, including a number of vasoactive cytokines resulting in acute allergic, or immediate (type I) hypersensitivity reactions [Gordon et al, Nature 346 : 274-276 (1990) & Galli, N. Engl. J. Med., 328 : 257- 265 (1993) ]. A crucial role for JAK3 in IgE receptor-mediated mast cell responses in vitro and in vivo has been established [Malaviya, et al, Biochem. Biophys. Res. Commun. 257 : 807-813 (1999) ]. In addition, the prevention of type I hypersensitivity reactions, including anaphylaxis, mediated by mast cell-activation through inhibition of JAK3 has also been reported [Malaviya et al, J. Biol.
Chem. 274 : 27028-27038 (1999) ]. Targeting mast cells with JAK3 inhibitors modulated mast cell degranulation in vitro and prevented IgE receptor/antigen-mediated anaphylactic reactions in vivo.
[00215] A recent study described the successful targeting of JAK3 for immune suppression and allograft acceptance. The study demonstrated a dose-dependent survival of buffalo heart allograft in Wistar Furth recipients upon administration of inhibitors of JAK3 indicating the possibility of regulating unwanted immune responses in graft versus host disease [Kirken, Transpl. Proc. 33: 3268-3270 (2001)].
[00216] IL-4-mediated STAT-phosphorylation has been implicated as the mechanism involved in early and late stages of rheumatoid arthritis (RA). Up-regulation of proinflammatory cytokines in RA synovium and synovial fluid is a characteristic of the disease. It has been demostrated that IL-4-mediated activation of IL-4/STAT pathway is mediated through the Janus kinases (JAK 1 & 3) and that IL-4-associated JAK kinases are expressed in the RA synovium [Muller-Ladner, et al, J. Immunol. 164: 3894-3901 (2000)].
[00217] Familial amyotrophic lateral sclerosis (FALS) is a fatal neurodegenerative disorder affecting about 10% of ALS patients. The survival rates of FALS mice were increased upon treatment with a JAK3 specific inhibitor. This confirmed that JAK3 plays a role in FALS [Trieu, et al, Biochem. Biophys. Res. Commun. 267: 22-25 (2000)].
[00218] Signal transducer and activator of transcription (STAT) proteins are activated by, among others, the JAK family kinases. Results form a recent study suggested the possibility of intervention in the JAK/STAT signaling pathway by targeting JAK family kinases with specific inhibitors for the treatment of leukemia [Sudbeck, et al., Clin. Cancer Res. 5 : 1569-1582 (1999) ]. JAK3 specific compounds were shown to inhibit the clonogenic growth of JAK3-expressing cell lines DAUDI, RAMOS, LC1 ; 19, NALM-6, MOLT-3 and HL-60. Inhibition of JAK3 and TYK 2 abrogated tyrosine phosphorylation of STAT3, and inhibited cell growth of mycosis fungoides, a form of cutaneous T cell lymphoma.
[002191 JAK3 has also been implicated in diabetes. A JAK3 inhibitor exhibited potent immunomodulatory activity and delayed the onset of diabetes in the NOD mouse model of autoimmune type 1 diabetes (Cetkovic-Cvrlje, et al. Clin. Immunol. 106: 213-225 (2003)).
[002201 According to another embodiment, the invention provides a method for treating or lessening the severity of a JAK3-mediated disease or condition in a patient comprising the step of administering to said patient a composition according to the present invention.
[002211 The term "JAK3-mediated disease", as used herein means any disease or other deleterious condition in which a JAK3 kinase is known to play a role.
Accordingly, another embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which JAK3 is known to play a role. Specifically, the present invention relates to a method of treating or lessening the severity of a disease or condition selected from immune responses such as allergic or type I hypersensitivity reactions, asthma, autoimmune diseases such as transplant rejection, graft versus host disease, rheumatoid arthritis, diabetes (e.g. type I
diabetes), amyotrophic lateral sclerosis, and multiple sclerosis, neurodegenerative disorders such as familial amyotrophic lateral sclerosis (FALS), as well as in solid and hematologic malignancies such as leukemias and lymphomas, wherein said method comprises administering to a patient in need thereof a composition according to the present invention.
[002221 The compounds and compositions, according to the method of the present invention, may be administered using any amount and any route of administration effective for treating or lessening the severity of cancer, an autoimmune disorder, a neurodegenerative or neurological disorder, schizophrenia, a bone-related disorder, liver disease, or a cardiac disorder. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of the infection, the particular agent, its mode of administration, and the like. Compounds of the invention are preferably formulated in dosage unit form for ease of administration and uniformity of dosage. The expression "dosage unit form" as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts.
The term "patient", as used herein, means an animal, preferably a mammal, and most preferably a human.
[002231 Pharmaceutically acceptable compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the infection being treated.
In certain embodiments, the compounds of the invention may be administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect.
[002241 Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents.
[002251 Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
[00226] Injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
[00227] In order to prolong the effect of a compound of the present invention, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection.
This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form.
Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled.
Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues.
[00228] Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.
[00229] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar--agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, 0 absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.
[002301 Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner.
Examples of embedding compositions that can be used include polymeric substances and waxes.
Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polethylene glycols and the like.
[002311 The active compounds can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art.
In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner.
Examples of embedding compositions that can be used include polymeric substances and waxes.
[002321 Dosage forms for topical or transdermal administration of a compound of this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required.
Ophthalmic formulation, ear drops, and eye drops are also contemplated as being within the scope of this invention. Additionally, the present invention contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body.
Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel.

Such disorders are described in detail herein.
[002391 Depending upon the particular condition, or disease, to be treated, additional therapeutic agents, which are normally administered to treat that condition, may also be present in the compositions of this invention. As used herein, additional therapeutic agents that are normally administered to treat a particular disease, or condition, are known as "appropriate for the disease, or condition, being treated."
[002401 For example, compounds of the present invention, or a pharmaceutically acceptable composition thereof, are administered in combination with chemotherapeutic agents to treat proliferative diseases and cancer. Examples of known chemotherapeutic agents include, but are not limited to, Adriamycin, dexamethasone, vincristine, cyclophosphamide, fluorouracil, topotecan, taxol, interferons, platinum derivatives, taxane (e.g., paclitaxel), vinca alkaloids (e.g., vinblastine), anthracyclines (e.g., doxorubicin), epipodophyllotoxins (e.g., etoposide), cisplatin, an mTOR inhibitor (e.g., a rapamycin), methotrexate, actinomycin D, dolastatin

[002431 In certain embodiments, compounds of the present invention, or a pharmaceutically acceptable composition thereof, are administered in combination with a monoclonal antibody or an siRNA therapeutic.
[002441 Those additional agents may be administered separately from an inventive compound-containing composition, as part of a multiple dosage regimen.
Alternatively, those agents may be part of a single dosage form, mixed together with a compound of this invention in a single composition. If administered as part of a multiple dosage regime, the two active agents may be submitted simultaneously, sequentially or within a period of time from one another normally within five hours from one another.
[002451 As used herein, the term "combination," "combined," and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a provided compound, an additional therapeutic agent, and a pharmaceutically acceptable carrier, adjuvant, or vehicle.
[002461 The amount of both, an inventive compound and additional therapeutic agent (in those compositions which comprise an additional therapeutic agent as described above)) that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. Preferably, compositions of this invention should be formulated so that a dosage of between 0.01 - 100 mg/kg body weight/day of an inventive can be administered.
[002471 In those compositions which comprise an additional therapeutic agent, that additional therapeutic agent and the compound of this invention may act synergistically.
Therefore, the amount of additional therapeutic agent in such compositions will be less than that required in a monotherapy utilizing only that therapeutic agent. In such compositions a dosage of between 0.01 - 1,000 pg/kg body weight/day of the additional therapeutic agent can be administered.
[002481 The amount of additional therapeutic agent present in the compositions of this invention will be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably the amount of additional therapeutic agent in the presently disclosed compositions will range from about 50% to 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent.
[002491 The compounds of this invention, or pharmaceutical compositions thereof, may also be incorporated into compositions for coating an implantable medical device, such as prostheses, artificial valves, vascular grafts, stents and catheters. Vascular stents, for example, have been used to overcome restenosis (re-narrowing of the vessel wall after injury).
However, patients using stents or other implantable devices risk clot formation or platelet activation. These unwanted effects may be prevented or mitigated by pre-coating the device with a pharmaceutically acceptable composition comprising a kinase inhibitor.
Implantable devices coated with a compound of this invention are another embodiment of the present invention.
5. Probe Compounds [002501 In certain aspects, a compound of the present invention may be tethered to a detectable moiety to form a probe compound. In one aspect, a probe compound of the invention comprises an irreversible protein kinase inhibitor of formula I-a or I-b, as described herein, a detectable moiety, and a tethering moiety that attaches the inhibitor to the detectable moiety.
[002511 In some embodiments, such probe compounds of the present invention comprise a provided compound of formula I-a or I-b tethered to a detectable moiety, Rr, by a bivalent tethering moiety, -T-. The tethering moiety may be attached to a compound of formula I-a or I-b via Ring A, Ring B, or R. One of ordinary skill in the art will appreciate that when a tethering moiety is attached to R', R' is a bivalent warhead group denoted as Rif. In certain embodiments, a provided probe compound is selected from any of formula V-a, V-b, VI-a, VI-b, VII-a, or VII-b:

N~W2 B (RX)m ~(RX)m VII-a VII-b, wherein each of Ring A, Ring B, R', in, p, Rx, RY, R ,W', and W2 is as defined above with respect to formulae I-a and I-b, and described in classes and subclasses herein, R', is a bivalent warhead group, T is a bivalent tethering moiety; and Rt is a detectable moiety.
[00252] In some embodiments, Rt is a detectable moiety selected from a primary label or a secondary label. In certain embodiments, Rt is a detectable moiety selected from a fluorescent label (e.g., a fluorescent dye or a fluorophore), a mass-tag, a chemiluminescent group, a chromophore, an electron dense group, or an energy transfer agent.
[00253] As used herein, the term "detectable moiety" is used interchangeably with the term "label" and "reporter" and relates to any moiety capable of being detected, e.g., primary labels and secondary labels. A presence of a detectable moiety can be measured using methods for quantifying (in absolute, approximate or relative terms) the detectable moiety in a system under study. In some embodiments, such methods are well known to one of ordinary skill in the art and include any methods that quantify a reporter moiety (e.g., a label, a dye, a photocrosslinker, a cytotoxic compound, a drug, an affinity label, a photoaffinity label, a reactive compound, an antibody or antibody fragment, a biomaterial, a nanoparticle, a spin label, a fluorophore, a metal-containing moiety, a radioactive moiety, quantum dot(s), a novel functional group, a group that covalently or noncovalently interacts with other molecules, a photocaged moiety, an actinic radiation excitable moiety, a ligand, a photoisomerizable moiety, biotin, a biotin analog (e.g., biotin sulfoxide), a moiety incorporating a heavy atom, a chemically cleavable group, a photocleavable group, a redox-active agent, an isotopically labeled moiety, a biophysical probe, a phosphorescent group, a chemiluminescent group, an electron dense group, a magnetic group, an intercalating group, a chromophore, an energy transfer agent, a biologically active agent, a detectable label, and any combination of the above).
[002541 Primary labels, such as radioisotopes (e.g., tritium, 32P 33P 35S 140 123I 124I 125I or 131I), mass-tags including, but not limited to, stable isotopes (e.g., 13C,2 H170 180, 15N 19F> and 127I , positron emitting isotopes (e.g., 110 18F 13N 124I and 150) and fluorescent labels are signal generating reporter groups which can be detected without further modifications.
Detectable moities may be analyzed by methods including, but not limited to fluorescence, positron emission tomography, SPECT medical imaging, chemiluminescence, electron-spin resonance, ultraviolet/visible absorbance spectroscopy, mass spectrometry, nuclear magnetic resonance, magnetic resonance, flow cytometry, autoradiography, scintillation counting, phosphoimaging, and electrochemical methods.
[002551 The term "secondary label" as used herein refers to moieties such as biotin and various protein antigens that require the presence of a second intermediate for production of a detectable signal. For biotin, the secondary intermediate may include streptavidin-enzyme conjugates. For antigen labels, secondary intermediates may include antibody-enzyme conjugates. Some fluorescent groups act as secondary labels because they transfer energy to another group in the process of nonradiative fluorescent resonance energy transfer (FRET), and the second group produces the detected signal.
[002561 The terms "fluorescent label", "fluorescent dye", and "fluorophore" as used herein refer to moieties that absorb light energy at a defined excitation wavelength and emit light energy at a different wavelength. Examples of fluorescent labels include, but are not limited to:

The synthesis and utility of these mass-tags is described in United States Patents 4,650,750, 4,709,016, 5,360,8191, 5,516,931, 5,602,273, 5,604,104, 5,610,020, and 5,650,270. Other examples of mass-tags include, but are not limited to, nucleotides, dideoxynucleotides, oligonucleotides of varying length and base composition, oligopeptides, oligosaccharides, and other synthetic polymers of varying length and monomer composition. A large variety of organic molecules, both neutral and charged (biomolecules or synthetic compounds) of an appropriate mass range (100-2000 Daltons) may also be used as mass-tags. Stable isotopes (e.g., 13C, 2H, 170, 180, and '5N) may also be used as mass-tags.
[002581 The term "chemiluminescent group," as used herein, refers to a group which emits light as a result of a chemical reaction without the addition of heat. By way of example, luminol (5-amino-2,3-dihydro-1,4-phthalazinedione) reacts with oxidants like hydrogen peroxide (H202) in the presence of a base and a metal catalyst to produce an excited state product (3-aminophthalate, 3-APA).
[002591 The term "chromophore," as used herein, refers to a molecule which absorbs light of visible wavelengths, UV wavelengths or IR wavelengths.

[002621 The term "energy transfer agent," as used herein, refers to a molecule which either donates or accepts energy from another molecule. By way of example only, fluorescence resonance energy transfer (FRET) is a dipole-dipole coupling process by which the excited-state energy of a fluorescence donor molecule is non-radiatively transferred to an unexcited acceptor molecule which then fluorescently emits the donated energy at a longer wavelength.
[002631 The term "moiety incorporating a heavy atom," as used herein, refers to a group which incorporates an ion of atom which is usually heavier than carbon. In some embodiments, such ions or atoms include, but are not limited to, silicon, tungsten, gold, lead, and uranium.

[00265] The term "photocaged moiety," as used herein, refers to a group which, upon illumination at certain wavelengths, covalently or non-covalently binds other ions or molecules.
[00266] The term "photoisomerizable moiety," as used herein, refers to a group wherein upon illumination with light changes from one isomeric form to another.
[00267] The term "radioactive moiety," as used herein, refers to a group whose nuclei spontaneously give off nuclear radiation, such as alpha, beta, or gamma particles; wherein, alpha particles are helium nuclei, beta particles are electrons, and gamma particles are high energy photons.
[00268] The term "spin label," as used herein, refers to molecules which contain an atom or a group of atoms exhibiting an unpaired electron spin (i.e. a stable paramagnetic group) that in some embodiments are detected by electron spin resonance spectroscopy and in other embodiments are attached to another molecule. Such spin-label molecules include, but are not limited to, nitryl radicals and nitroxides, and in some embodiments are single spin-labels or double spin-labels.
[00269] The term "quantum dots," as used herein, refers to colloidal semiconductor nanocrystals that in some embodiments are detected in the near-infrared and have extremely high quantum yields (i.e., very bright upon modest illumination).
[00270] One of ordinary skill in the art will recognize that a detectable moiety may be attached to a provided compound via a suitable substituent. As used herein, the term "suitable substituent" refers to a moiety that is capable of covalent attachment to a detectable moiety.
Such moieties are well known to one of ordinary skill in the art and include groups containing, e.g., a carboxylate moiety, an amino moiety, a thiol moiety, or a hydroxyl moiety, to name but a few. It will be appreciated that such moieties may be directly attached to a provided compound or via a tethering moiety, such as a bivalent saturated or unsaturated hydrocarbon chain.

[00285] One of ordinary skill in the art will appreciate that when -T-R is attached to a compound of formula I-a or I-b via the R1 warhead group, then the resulting tethering moiety comprises the R1 warhead group. As used herein, the phrase "comprises a warhead group"
means that the tethering moiety formed by -R''-T- of formula V-a or V-b is either substituted with a warhead group or has such a warhead group incorporated within the tethering moiety. For example, the tethering moiety formed by -R''-T- may be substituted with an -L-Y warhead group, wherein such groups are as described herein. Alternatively, the tethering moiety formed by -R''-T- has the appropriate features of a warhead group incorporated within the tethering moiety. For example, the tethering moiety formed by -R'1-T- may include one or more units of unsaturation and optional substituents and/or heteroatoms which, in combination, result in a moiety that is capable of covalently modifying a protein kinase in accordance with the present invention. Such -R'-T- tethering moiety are depicted below.

[002431 In certain embodiments, compounds of the present invention, or a pharmaceutically acceptable composition thereof, are administered in combination with a monoclonal antibody or an siRNA therapeutic.
[002441 Those additional agents may be administered separately from an inventive compound-containing composition, as part of a multiple dosage regimen.
Alternatively, those agents may be part of a single dosage form, mixed together with a compound of this invention in a single composition. If administered as part of a multiple dosage regime, the two active agents may be submitted simultaneously, sequentially or within a period of time from one another normally within five hours from one another.
[002451 As used herein, the term "combination," "combined," and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention may be administered with another therapeutic agent simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a provided compound, an additional therapeutic agent, and a pharmaceutically acceptable carrier, adjuvant, or vehicle.
[002461 The amount of both, an inventive compound and additional therapeutic agent (in those compositions which comprise an additional therapeutic agent as described above)) that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. Preferably, compositions of this invention should be formulated so that a dosage of between 0.01 - 100 mg/kg body weight/day of an inventive can be administered.
[002471 In those compositions which comprise an additional therapeutic agent, that additional therapeutic agent and the compound of this invention may act synergistically.
Therefore, the amount of additional therapeutic agent in such compositions will be less than that required in a monotherapy utilizing only that therapeutic agent. In such compositions a dosage of between 0.01 - 1,000 pg/kg body weight/day of the additional therapeutic agent can be administered.
[002481 The amount of additional therapeutic agent present in the compositions of this invention will be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably the amount of additional therapeutic agent in the presently disclosed compositions will range from about 50% to 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent.
[002491 The compounds of this invention, or pharmaceutical compositions thereof, may also be incorporated into compositions for coating an implantable medical device, such as prostheses, artificial valves, vascular grafts, stents and catheters. Vascular stents, for example, have been used to overcome restenosis (re-narrowing of the vessel wall after injury).
However, patients using stents or other implantable devices risk clot formation or platelet activation. These unwanted effects may be prevented or mitigated by pre-coating the device with a pharmaceutically acceptable composition comprising a kinase inhibitor.
Implantable devices coated with a compound of this invention are another embodiment of the present invention.

[00253] As used herein, the term "detectable moiety" is used interchangeably with the term "label" and "reporter" and relates to any moiety capable of being detected, e.g., primary labels and secondary labels. A presence of a detectable moiety can be measured using methods for quantifying (in absolute, approximate or relative terms) the detectable moiety in a system under study. In some embodiments, such methods are well known to one of ordinary skill in the art and include any methods that quantify a reporter moiety (e.g., a label, a dye, a photocrosslinker, a cytotoxic compound, a drug, an affinity label, a photoaffinity label, a reactive compound, an antibody or antibody fragment, a biomaterial, a nanoparticle, a spin label, a fluorophore, a metal-containing moiety, a radioactive moiety, quantum dot(s), a novel functional group, a group that covalently or noncovalently interacts with other molecules, a photocaged moiety, an actinic radiation excitable moiety, a ligand, a photoisomerizable moiety, biotin, a biotin analog (e.g., biotin sulfoxide), a moiety incorporating a heavy atom, a chemically cleavable group, a photocleavable group, a redox-active agent, an isotopically labeled moiety, a biophysical probe, a phosphorescent group, a chemiluminescent group, an electron dense group, a magnetic group, an intercalating group, a chromophore, an energy transfer agent, a biologically active agent, a detectable label, and any combination of the above).
[002541 Primary labels, such as radioisotopes (e.g., tritium, 32P 33P 35S 140 123I 124I 125I or 131I), mass-tags including, but not limited to, stable isotopes (e.g., 13C,2 H170 180, 15N 19F> and 127I , positron emitting isotopes (e.g., 110 18F 13N 124I and 150) and fluorescent labels are signal generating reporter groups which can be detected without further modifications.
Detectable moities may be analyzed by methods including, but not limited to fluorescence, positron emission tomography, SPECT medical imaging, chemiluminescence, electron-spin resonance, ultraviolet/visible absorbance spectroscopy, mass spectrometry, nuclear magnetic resonance, magnetic resonance, flow cytometry, autoradiography, scintillation counting, phosphoimaging, and electrochemical methods.
[002551 The term "secondary label" as used herein refers to moieties such as biotin and various protein antigens that require the presence of a second intermediate for production of a detectable signal. For biotin, the secondary intermediate may include streptavidin-enzyme conjugates. For antigen labels, secondary intermediates may include antibody-enzyme conjugates. Some fluorescent groups act as secondary labels because they transfer energy to another group in the process of nonradiative fluorescent resonance energy transfer (FRET), and the second group produces the detected signal.
[002561 The terms "fluorescent label", "fluorescent dye", and "fluorophore" as used herein refer to moieties that absorb light energy at a defined excitation wavelength and emit light energy at a different wavelength. Examples of fluorescent labels include, but are not limited to:

The synthesis and utility of these mass-tags is described in United States Patents 4,650,750, 4,709,016, 5,360,8191, 5,516,931, 5,602,273, 5,604,104, 5,610,020, and 5,650,270. Other examples of mass-tags include, but are not limited to, nucleotides, dideoxynucleotides, oligonucleotides of varying length and base composition, oligopeptides, oligosaccharides, and other synthetic polymers of varying length and monomer composition. A large variety of organic molecules, both neutral and charged (biomolecules or synthetic compounds) of an appropriate mass range (100-2000 Daltons) may also be used as mass-tags. Stable isotopes (e.g., 13C, 2H, 170, 180, and '5N) may also be used as mass-tags.
[002581 The term "chemiluminescent group," as used herein, refers to a group which emits light as a result of a chemical reaction without the addition of heat. By way of example, luminol (5-amino-2,3-dihydro-1,4-phthalazinedione) reacts with oxidants like hydrogen peroxide (H202) in the presence of a base and a metal catalyst to produce an excited state product (3-aminophthalate, 3-APA).
[002591 The term "chromophore," as used herein, refers to a molecule which absorbs light of visible wavelengths, UV wavelengths or IR wavelengths.
[002601 The term "dye," as used herein, refers to a soluble, coloring substance which contains a chromophore.

[002621 The term "energy transfer agent," as used herein, refers to a molecule which either donates or accepts energy from another molecule. By way of example only, fluorescence resonance energy transfer (FRET) is a dipole-dipole coupling process by which the excited-state energy of a fluorescence donor molecule is non-radiatively transferred to an unexcited acceptor molecule which then fluorescently emits the donated energy at a longer wavelength.
[002631 The term "moiety incorporating a heavy atom," as used herein, refers to a group which incorporates an ion of atom which is usually heavier than carbon. In some embodiments, such ions or atoms include, but are not limited to, silicon, tungsten, gold, lead, and uranium.
[00264] The term "photoaffinity label," as used herein, refers to a label with a group, which, upon exposure to light, forms a linkage with a molecule for which the label has an affinity.
[00265] The term "photocaged moiety," as used herein, refers to a group which, upon illumination at certain wavelengths, covalently or non-covalently binds other ions or molecules.
[00266] The term "photoisomerizable moiety," as used herein, refers to a group wherein upon illumination with light changes from one isomeric form to another.
[00267] The term "radioactive moiety," as used herein, refers to a group whose nuclei spontaneously give off nuclear radiation, such as alpha, beta, or gamma particles; wherein, alpha particles are helium nuclei, beta particles are electrons, and gamma particles are high energy photons.
[00268] The term "spin label," as used herein, refers to molecules which contain an atom or a group of atoms exhibiting an unpaired electron spin (i.e. a stable paramagnetic group) that in some embodiments are detected by electron spin resonance spectroscopy and in other embodiments are attached to another molecule. Such spin-label molecules include, but are not limited to, nitryl radicals and nitroxides, and in some embodiments are single spin-labels or double spin-labels.
[00269] The term "quantum dots," as used herein, refers to colloidal semiconductor nanocrystals that in some embodiments are detected in the near-infrared and have extremely high quantum yields (i.e., very bright upon modest illumination).
[00270] One of ordinary skill in the art will recognize that a detectable moiety may be attached to a provided compound via a suitable substituent. As used herein, the term "suitable substituent" refers to a moiety that is capable of covalent attachment to a detectable moiety.
Such moieties are well known to one of ordinary skill in the art and include groups containing, e.g., a carboxylate moiety, an amino moiety, a thiol moiety, or a hydroxyl moiety, to name but a few. It will be appreciated that such moieties may be directly attached to a provided compound or via a tethering moiety, such as a bivalent saturated or unsaturated hydrocarbon chain.
[00271] In some embodiments, detectable moieties are attached to a provided compound via click chemistry. In some embodiments, such moieties are attached via a 1,3-cycloaddition of an azide with an alkyne, optionally in the presence of a copper catalyst.

[00285] One of ordinary skill in the art will appreciate that when -T-R is attached to a compound of formula I-a or I-b via the R1 warhead group, then the resulting tethering moiety comprises the R1 warhead group. As used herein, the phrase "comprises a warhead group"
means that the tethering moiety formed by -R''-T- of formula V-a or V-b is either substituted with a warhead group or has such a warhead group incorporated within the tethering moiety. For example, the tethering moiety formed by -R''-T- may be substituted with an -L-Y warhead group, wherein such groups are as described herein. Alternatively, the tethering moiety formed by -R''-T- has the appropriate features of a warhead group incorporated within the tethering moiety. For example, the tethering moiety formed by -R'1-T- may include one or more units of unsaturation and optional substituents and/or heteroatoms which, in combination, result in a moiety that is capable of covalently modifying a protein kinase in accordance with the present invention. Such -R'-T- tethering moiety are depicted below.

Omnia Assay Protocol for Potency Assessment Against BTK
[001358] Below describes the protocol using EGFR-WT and EGFR-T790M/L858R and the protocol BTK-optimized reagent conditions then follow.
[001359] The mechanics of the assay platform are best described by the vendor (Invitrogen, Carlsbad, CA) on their website at the following URL:
www.invitrogen.com/content.cfin?pageid-l 1338 or www.invitrogen.com/site/uslen/home/Products-and-Services/Applications/Drug-Discovery/Target-and-Lead-Identification-and-Validation/KinaseBiology/KB-Misc/Biochemical-Assays/Omnia-Kinase-Assays.html.
[001360] Briefly, lOX stocks of EGFR-WT (PV3872) from Invitrogen and EGFR-T790M/L858R (40350) from BPS Bioscience, San Diego, CA, 1.13X ATP (ASOO1A) and appropriate Tyr-Sox conjugated peptide substrates (KCZ1001) were prepared in 1X kinase reaction buffer consisting of 20 mM Tris, pH 7.5, 5 mM MgC12, 1 mM EGTA, 5 mM
(3-glycerophosphate, 5% glycerol (lOX stock, KBO02A) and 0.2 mM DTT (DSOO1A). 5 L of each enzyme were pre-incubated in a Coming (#3574) 384-well, white, non-binding surface microtiter plate (Corning, NY) for 30 min. at 27 C with a 0.5 L volume of 50%
DMSO and serially diluted compounds prepared in 50% DMSO. Kinase reactions were started with the addition of 45 L of the ATP/Tyr-Sox peptide substrate mix and monitored every 30-90 seconds for 60 minutes at &ex360/&em485 in a Synergy4 plate reader from BioTek (Winooski, VT). At the conclusion of each assay, progress curves from each well were examined for linear reaction kinetics and fit statistics (R2, 95% confidence interval, absolute sum of squares). Initial velocity (0 minutes to -30 minutes) from each reaction was determined from the slope of a plot of relative fluorescence units vs time (minutes) and then plotted against inhibitor concentration to estimate IC50 from log[Inhibitor] vs Response, Variable Slope model in GraphPad Prism from GraphPad Software (San Diego, CA).
[0013611 The modified BTK-optimized reagent conditions for the above protocol are:
[BTK] - 5 nM, [ATP] - 40 mM, [Y5-Sox] - 10 mM (ATP KMapp - 36 mM).
[0013621 Table 6 shows the activity of selected compounds of this invention in the BTK
inhibition assay. The compound numbers correspond to the compound numbers in Table 5.
Compounds having an activity designated as "A" provided an ICso <10 nM;
compounds having an activity designated as "B" provided an ICso 10-100 nM; compounds having an activity designated as "C" provided an ICs0 of 100-1000 nM; compounds having an activity designated as "D" provided an IC50 of 1000-10,000 nM; and compounds having an activity designated as "E" provided an IC50 >10,000 nM.

Ramos cells were grown in suspension in T225 flasks, spun down, resuspended in 50 ml serum-free media and incubated for 1 hour. Compound was added to Ramos cells in serum free media to a final concentration of 1, 0.1, 0.01, or 0.001 M. Ramos cells were incubated with compound for 1 hour, washed again and resuspended in 100u1 serum-free media.
Cells were then stimulated with 1 g of goat F(ab')2 Anti-Human IgM and incubated on ice for 10 minutes to activate B cell receptor signaling pathways. After 10 minutes, the cells were washed once with PBS and then lysed on ice with Invitrogen Cell Extraction buffer. 16 g total protein from lysates were loaded on gel and blots were probed for phosphorylation of the BTK substrate PLC72. Dose response inhibition of BTK signaling in Ramos cells is depicted in Figures 1, 2, 3, 4 and 5.

Table 7. BTK Ramos Cellular Inhibition Data Compound # BTK Inhibition Compound # BTK Inhibition Compound # BTK Inhibition Washout Experiment with Ramos cells [001365] Ramos cells were serum starved for one hour in RPMI media +l%
glutamine at 37 C. After starvation, Ramos cells were treated with 100nM compound diluted in serum free RPMI media for 1 hour. After compound treatment, the media was removed and cells were washed with compound-free media. Subsequently, Ramos cells were washed every 2 hours and resuspended in fresh compound-free media. Cells were collected at specified timepoints, treated with lug anti-human IgM (Southern Biotech cat # 2022-01) for 10 minutes on ice to induce BCR
signaling and then washed in PBS. Ramos cells were then lysed in Cell Extraction Buffer (Invitrogen FNNOO11) supplemented with Roche complete protease inhibitor tablets (Roche 11697498001) and phosphatase inhibitors (Roche 04 906 837 001) and l8ug total protein lysate was loaded in each lane. Inhibition of BTK kinase activity was assayed by measuring its substrate (PLCy2) phosphorylation by western blot with phospho-specific antibodies from Cell Signaling Technologies cat# 3871. The results of this experiment with compounds 1-2, 1-4 and I-7 are depicted in Figures 1, 2 and 3.

[001367] Intact BTK was incubated for 1 hr at a l OX fold excess of 1-7 to protein. Aliquots (2 l) of the samples were diluted with 10 l of 0.1 % TFA prior to micro C4 ZipTipping directly onto the MALDI target using Sinapinic acid as the desorption matrix (10 mg/ml in 0.1%
TFA:Acetonitrile 20:80). See Figure 15. Top panel shows the mass spec trace of the intact BTK
protein (m/z 81,032 Da). The bottom panel shows mass spec trace when BTK was incubated with 1-7 (mw=345.4). The centroid mass (m/z= 81,403 Da) shows a positive shift of about 371.1 Da indicating complete modification of BTK by 1-7. Other compounds that completely modify BTK include 1-96, 1-71, 1-149, 1-161, 1-163, 1-182, 1-195, 1-207, 1-219, and 1-244.
Human primary B cell proliferation assay [0013681 Human naive B cells were purified from 100 mL whole blood using a MACS
purification kit designed to isolate CD19+, IgD+ cells by negative selection.
Purified naive B
cells were resuspended in RPMI complete and stimulated with 5 g/ml a-IgM for 72 hours. 3H-Thymidine was included in the culture media for the final 16h, cells were harvested and 3H
incorporation measured. Inhibition of B cell proliferation correlates with inhibition of BTK
substrate phosphorylation after a-IgM stimulation. Importantly, a molecule with the same scaffold as 1-7 but biochemically inactive against BTK, IR-7, is not active in the naive B cell proliferation assay.

A control sample (45 pmols) was also prepared which did not have the addition of (1-2). For tryptic digests a 5ul aliquot (7.5 pmols) was diluted with 15 ul of 0.1%
TFA prior to micro C18 Zip Tipping directly onto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as the matrix (5mg/ml in 0.1% TFA:Acetonitrile 50:50).
[0013741 As depicted in Figure 6, the expected peptide (GCLLNFLR) to be modified was immediately evident after reaction with 1-2 (MI mass of 359.17 Da) at MH+ of 1294.72. The peptide was also quite evident in the control sample as modified by lodacetamide at MH+ of 992.56. Interestingly the iodoacetamide modified peptide was not evident in the digest reacted with compound 1-2 indicating that the reaction was complete. There was no evidence of other modified peptides.
[001375] Evidence of compound 1-2 was observed at MH+ of 360.17 in the low mass range of the spectra. The fragmentation spectra of the 360.17 peak did show diagnostic fragments that were apparent in the PSD spectra of the modified peptide at 1294.72 (See Figure 6).
[001376] To further verify the presence of the modified peptides, both the iodoacetamide labeled (992.56) and 1-2 labeled (1294.72) were subjected to PSD (MS/MS) analsysis. After a database search of the NCBI nr Homo sapien database using Mascot MS/MS Ion Search program the top match was the expected peptide in both cases.
Instrumental:
[001377] For tryptic digests the instrument was set in Reflectron mode with a pulsed extraction setting of 2200. Calibration was done using the Laser Biolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20). For CID/PSD analysis the peptide was selected using cursors to set ion gate timing and fragmentation occurred at a laser power about 20%
higher and He was used as the collision gas for CID. Calibration for fragments was done using the P 14R fragmentation calibration for the Curved field Reflectron.
Mass Spectrometry for TEC Kinase (Compound 1-4) [001378] TEC kinase (45 pmols; Invitrogen) was incubated with (1-4) (450 pmols) for 3hrs at lOX excess prior to tryptic digestion. lodoacetamide was used as the alkylating agent after compound incubation. A control sample (45 pmols) was also prepared which did not have the addition of (1-4). For tryptic digests a 5ul aliquot (7.5 pmols) was diluted with 15 ul of 0.1%
TFA prior to micro C18 Zip Tipping directly onto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as the matrix (5mg/ml in 0.1%TFA:Acetonitrile 50:50).
[001379] As depicted in Figure 7, the expected peptide (GCLLNFLR) to be modified was immediately evident at MH+ of 1355.72. This is the mass to be expected when compound 1-4, with an adduct mass of 420.21, is added to the peptide mass of 935.51. The peptide was also quite evident in the control sample as modified by lodacetamide at MH+ of 992.56.
Interestingly the iodoacetamide modified peptide was not evident in the digest reacted with compound 1-4 indicating that the reaction was complete. There was no evidence of other modified peptides.
[001380] Evidence of compound 1-4 was observed at MH+ of 421.35 in the low mass range of the spectra. The fragmentation spectra of the 421.35 peak did reveal two prominent peaks that were apparent in the PSD spectra of the modified peptide at 1355.72 (See Figure 7).
[001381] To further verify the presence of the modified peptide with compound 1-4, the peptide at MH+ of 1355.72 was subjected to PSD (MS/MS) analsysis. Because of the low intensity of fragments, a database correlation was not possible. However, diagnostic fragments from the 1-4 molecule itself provided confidnece in the identification.
Diagnostic fragments at MH+ of 376.38 and 421.83 are from I-4.
Instrumental: .
[001382] For tryptic digests the instrument was set in Reflectron mode with a pulsed extraction setting of 1800. Calibration was done using the Laser Biolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20). For CID/PSD analysis the peptide was selected using cursors to set ion gate timing and fragmentation occurred at a laser power about 20%
higher and He was used as the collision gas for CID. Calibration for fragments was done using the P 14R fragmentation calibration for the Curved field Reflectron.
Mass Spectrometry for TEC Kinase (Compound 1-7) [001383] TEC kinase (45 pmols; Invitrogen) was incubated with (1-7) (450 pmols) for 3hrs at lOX excess prior to tryptic digestion. lodoacetamide was used as the alkylating agent after compound incubation. A control sample (45 pmols) was also prepared which did not have the addition of (1-7). For tryptic digests a 5ul aliquot (7.5 pmols) was diluted with 15 ul of 0.1%
TFA prior to micro C18 Zip Tipping directly onto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as the matrix (5mg/ml in 0.l%TFA:Acetonitrile 50:50).
[001384] As depicted in Figure 8, the expected peptide (GCLLNFLR) to be modified was immediately evident at MH+ of 1280.73. This is the mass to be expected when compound 1-7, with an adduct mass of 345.16, is added to the peptide mass of 935.51. The peptide was also quite evident in the control sample as modified by lodacetamide at MH+ of 992.56.
Interestingly the iodoacetamide modified peptide was not evident in the digest reacted with compound 1-7 indicating that the reaction was complete. There was no evidence of any other modified peptide at MH+ of 1985.93 (TIDELVECEETFGR).
[001385] Evidence of compound 1-7 was observed at MH+ of 346.32 in the low mass range of the spectra. The fragmentation spectra of the 346.32 peak did show many diagnostic fragments that were apparent in the PSD spectra of the two modified peptides (See Figure 8).
[001386] To further verify the presence of the modified peptides with compound 1-7, the peptides at MH+ of 1280.73 and 1985.93 were subjected to PSD (MS/MS) analsysis. A
correlational analysis with the homosapien database identified the correct peptide modified by I-7.

To make the EGFR-mutant protein, the cysteine at position 797 was changed to a serine using the Stratagene QuikChange kit (Stratagene, Cedar Creek, TX), according to manufacturer's instructions.
(ii) Expression [0013931 P1 baculovirus stocks were generated in SF9 cells via Blue Sky Biotech's suspension transfection protocol (Worcester, MA). Expression analysis was conducted in 125 ml culture of SF21 insect cells ((grown in SF9001 SFM (Invitrogen cat # 10902-088), supplemented with lOmg/L gentamicin (Invitrogen, Carlsbad, CA, cat# 15710-064)) using a viral load of 0.lml of virus per 100 ml of cell suspension. Expression was optimized using Blue Sky Biotech's Infection Kinetics Monitoring system (Worcester, MA).
(iii) Purification [001394] Infected insect cells were pelleted. Cell pellets were resuspended in Blue Sky Biotech's lysis buffer (Worcester, MA, 1X WX; solubilization buffer, containing a protease inhibitor cocktail of leupeptin, pepstatin, PMSF, aprotinin and EDTA) at a ratio of 10 ml per gram of wet cell paste.Cells were lysed by sonication and the lysate was clarified by centrifugation at 9,000 RPM for 30 minutes in a GSA rotor. 500 l bed volume of NiNTA resin (Qiagen, Valencia, CA) was added to the supernatants and batch bound for two hours with constant agitation. The material was transferred by gravity into an empty 2ml column. The column was washed with 2 ml of wash buffer (Blue Sky Biotech, Worcester, MA, lX WX, 25mM imidazole ).The protein was eluted with lX WX + imidazole at varying concentrations:
Elution 1: 75 mM imidazole (2 fractions, 1 column volume); Elution 2 : 150 mM
imidazole (2 fractions, 1 column volume); Elution 3 : 300 mM imidazole (2 fractions, 1 column volume). All the elution fractions were analyzed by SDS page followed by Coomassie staining and Western Blotting using anti-penta-his antibody (Qiagen, Valencia, CA). The carboxy-terminal six-histidine "tag" was removed from some of the purified protein using AcTEV
Protease kit ( Invitrogen, Carlsbad, CA, Cat# 12575-015), following manufacturer's instructions. All the samples (pre- and post- Tev cut) were analyzed by SDS page followed by Coomassie staining and Western Blotting, as described above.
Mass Spectrometry for EGFR
[001395] EGFR wild type and EGFR (mutant C797S) is incubated with 10-fold excess of test compound for 1 hr and 3 hrs. 1 l aliquots of the samples (total volume 5-8 ul) are diluted with 10 ul of 0.1 % TFA prior to micro C4 ZipTipping directly onto the MALDI
target using Sinapinic acid as the desorption matrix (10 mg/ml in 0.1%TFA:Acetonitrile 50:50). Intact mass measurement reveals that the wild type has a nominal mass of about 37557 and the mutant slightly lower at 37500. Reactivity is only observed for the wild type EGFR
with a new peak appearing at a mass consistent with a single site covalent modification with test compound which has a mass of 410 Da.
Omnia Assay Protocol for Potency Assessment Against EGFR (WT) and EGFR
(T790M/L858R) Active Enzymes [0013961 The Omnia Assay Protocol for potency assessment against EGFR is performed as described in Example 251 above except that the EGFR-WT- and EGFR T790M/L858R-modified optimized reagent conditions are:
[0013971 [EGFR-WT] - 5 nM, [ATP] - 15 mM, [Y12-Sox] - 5 mM (ATP KMapp - 12 mM); and [EGFR-T790M/L858R] - 3 nM, [ATP] - 50 mM, [Y12-Sox] - 5 mM (ATP KMapp 45 mM).

Natl.
Acad. Sci. USA Vol 95, pp 12022-12027, 1998. Specifically, A431 human epidermoid carcinoma cells were grown in 6-well plates to 90% confluence and then incubated in serum-free media for 18 hr. Duplicate sets of cells were treated with 1 M designated compound for 2, 5, 10, 30, or 60 min. Cells were washed free of the compound with warmed serum-free medium, incubated for 2 hr, washed again, incubated another 2 hr, washed again, and then incubated another 2 hr washed again and incubated for additional 2 hr and then stimulated with 100 ng/ml EGF for 5 min. Extracts were made as described Fry, et al.
[0014001 Compounds were assayed in A431 human epidermoid carcinoma cells using a method substantially similar to that described in Fry, et al. Specifically, A431 human epidermoid carcinoma cells were grown in 6-well plates to 90% confluence and then incubated in serum-free media for 18 hr. Cells were then treated with 10, 1, 0.1, 0.01, or 0.001 M test compound for 1 hr. Cells were then stimulated with 100 ng/ml EGF for 5 min, and extracts were made as described in Fry, et al. 20ug total protein from lysates were loaded on gel and blots were probed for either EGFR phosphorylation or p42/p44 Erk phosphorylation.
Washout Experiment for EGFR Activity [0014011 A431 human epidermoid carcinoma cells were grown in 6-well plates to '90%
confluence and then incubated in serum-free media for 18 hr. Duplicate sets of cells were treated with 1 M designated compound for 1 hr. One set of cells was then stimulated with 100 ng/ml EGF for 5 min, and extracts were made as described. The other set of cells was washed free of compound 1-7 with warmed compound-free medium, incubated for 2 hr, washed again, incubated another 2 hr, washed again, and then incubated another 2 hr washed again and incubated for additional 2 hr and then stimulated with EGF. The results of this experiment with compound 1-7 are depicted in Figure 10.
Washout Experiment in HCC827 cells containing EGFR deletion mutantHCC827 [0014021 Cells (ATCC, Manassas,VA) were plated in Growth Media (RPMI 1640) supplemented with 10% FBS,10uM HEPES, 2mM 1-glutamine, 1mM NaPyruvate and pen/strep (Invitrogen, Carlsbad, CA) at a density of 2.5 x 10 5 cells per well in 6 well tissue culture plates.
Twenty four hours later the cells were washed 2 x with PBS then serum starved overnight in Basal Media (Growth Media without FBS).
[0014031 The following morning the media was removed and 2 ml fresh Basal Media containing luM compound in 0.1% DMSO was added to duplicate wells. At 1 hour, one well of cells was treated with 100 ng/ml of EGF for 5 minutes, rinsed with PBS, then lysed by scraping into 75 ul of Cell Extraction Buffer (Invitrogen, Carlsbad, CA) plus PhosSTOP
Phosphatase Inhibitor and Complete Protease Inhibitor (Roche, Indianapolis, IN) for the Oh time point. The compound was removed from the second set of wells and they were washed 2X with Basal Media. The cells were washed with Basal Media every 2 hours until 8 hours when they were treated with EGF and lysed as at the 0 h time point.
[0014041 Lysate protein concentrations were determined by BCA Assay (Pierce, Rockford, IL) and 10 ug of each lysate was separated by 4-12% gradient SDS-PAGE
(Invitrogen), transferred to Immobilon-FL membrane (Millipore) and probed with rabbit anti-Phospho-EGFR
(Tyr1068) (Zymed-now Invitrogen) and mouse anti-EGFR (Cell Signaling Technologies, Danvers, MA) antibodies. Phospho-protein signals were quantitated using Odyssey Infrared Imagning (Li-Cor Biosciences, Lincoln, Nebraska). The results of this experiment are depicted in Figure 9 where it shows compound 1-2 compared to results of compound 1-4 and compound I-7 in the same "washout" experiment.
Mass Spectrometry for ERBB4 [0014051 Erbb4 kinase domain (Upstate) was incubated with compound for 60 minutes at 10-fold excess of compound 1-4 and I-11 to protein. 1 l aliquots of the samples (total volume of 4.24u1) were diluted with 10 l of 0.1 % TFA prior to micro C4 ZipTipping directly onto the MALDI target using Sinapinic acid as the desorption matrix (10 mg/ml in 0.1%TFA:Acetonitrile 50:50). For intact protein mass measurement the instrument was set in Linear mode using a pulsed extraction setting of 16,952 for the myoglobin standard used to calibrate the instrument (Shimadzu Axima TOF2).
[0014061 Intact ErbB4 protein occurs at MH+ of 35850 with corresponding sinapinic (matrix) adducts occurring about 200 Da higher. A stochiometric incorporation of the test compound (1-4 and I-11) (Mw of 410 Da) produced a new mass peak which is approximately 410 Da higher (MH+ of 36260). This is consistent with covalent modification of ErbB4 with compounds 1-4 and I-11.
ErbB1, ErbB2 and/or ErbB4 Kinase Inhibition [0014071 Compounds of the present invention were assayed as inhibitors of one or more of ErbB 1, ErbB2, and/or ErbB4 in a manner substantially similar to the method described by Invitrogen Corp (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California, CA;
http://www.invitrogen.com/downloads/Z-LYTE_Brochure_1205.pdf) using the Z'-LYTETM
biochemical assay procedure or similar biochemical assay. The Z'-LYTETM
biochemical assay employs a fluorescence-based, coupled-enzyme format and is based on the differential sensitivity of phosphorylated and non-phosphorylated peptides to proteolytic cleavage.
Using this assay, Compound 1-56 was found to inhibit ERBB1 with an IC50 of 2,233 nM. Using this assay, Compound 1-56 was found to inhibit ERBB4 (HER4) with an ICso of 2,165 nM.
Mass Spectrometry for Janus-3 Kinase (JAK3) [0014081 JAK3 kinase (33 pmols; Invitrogen) was incubated with (1-7) (327 pmols) for 3hrs at lOX excess prior to tryptic digestion. Iodoacetamide was used as the alkylating agent after compound incubation. For tryptic digests a 5ul aliquot (5.5 pmols) was diluted with 15 ul of 0.1% TFA prior to micro C18 Zip Tipping directly onto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as the matrix (5mg/ml in 0.1%TFA:Acetonitrile 50:50).
[001409] As depicted in Figure 11, the expected peptide (LVMEYLPSGCLR) to be modified was immediately evident as the largest peak at MH+ of 1725.88. This is the mass to be expected when compound 1-7, with an adduct mass of 345.16, is added to the peptide mass of 1380.70. Interestingly the iodoacetamide modified peptide was not evident at MH+ of 1437.73 in the digest reacted with compound 1-7 indicating that the reaction was not entirely complete.
There was also evidence for a number of other modified peptides, however, their signals were low.
[001410] Evidence of compound 1-7 was observed at MH+ of 346.12 in the low mass range of the spectra. The fragmentation spectra of the 346.12 peak did not show diagnostic fragments that were apparent in the PSD spectra of the modified peptides (See Figure 11).
[001411] To further verify the presence of the modified peptides with compound 1-7, the peptides at MH+ of 1725.88 and 1118.55 were subjected to PSD (MS/MS) analsysis. A
correlational analysis with the homosapien database identified the correct peptides as being modified by 1-7. Compound I-11 was also tested using the same procedure and showed measurable modification.
Instrumental:
[001412] For tryptic digests the instrument was set in Reflectron mode with a pulsed extraction setting of 2200. Calibration was done using the Laser Biolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20). For CID/PSD analysis the peptide was selected using cursors to set ion gate timing and fragmentation occurred at a laser power about 20%
higher and He was used as the collision gas for CID. Calibration for fragments was done using the P 14R fragmentation calibration for the Curved field Reflectron.
Omnia Assay Protocol for Potency Assessment Against the Active Form of JAK3:
[001413] The Omnia Assay Protocol for potency assessment against JAK3 was performed in a substantially similar manner as that described in Example 251 above except that the modified JAK3-optimized reagent conditions were:
[JAK3] - 5 nM, [ATP] - 5 M, [Y12-Sox] - 5 M (ATP KMapp -5 M).
[001414] Table 18 shows the activity of selected compounds of this invention in the JAK3 inhibition assay. The compound numbers correspond to the compound numbers in Table 5.
Compounds having an activity designated as "A" provided an IC50 <10 nM;
compounds having an activity designated as "B" provided an IC50 10-100 nM; compounds having an activity designated as "C" provided an ICso of 100-1000 nM; compounds having an activity designated as "D" provided an IC50 of 1000-10,000 nM; and compounds having an activity designated as "E" provided an IC50 >10,000 nM.
Table 18. JAK3 Inhibition Data Compound # JAK3 Inhibition Compound # JAK3 Inhibition JAK3 Cellular Assay Protocol in CTLL2 Cells [0014151 Compounds 1-2, 1-4 and 1-7 were tested in the following protocol.
CTLL2: murine lymphoma cell line ATCC: TIB-214. 5x106 cells/sample were IL-2 starved in RPMI-1640 media for 2 hours. Designated samples were then treated with compound for 90 minutes. Samples, except DMSO control were then stimulated with I OOnM IL-2 for 10 minutes.
Samples were lysed and subjected to Western Analysis. The results are displayed in Figure 12, Figure 13 and Figure 14.
BTK occupancy in Ramos cells with 1-7 and 1-215 using streptavidin beads [0014161 Ramos cells were incubated with 0.1, 0.05, 0.01, or 0.001 pM 1-7 in serum free media for 1 hour at 37 T. The cells were pelleted by centrifugation and lysed in Cell Extraction buffer (Invitrogen) for 10 minutes on ice, centrifuged (10 minutes at 14,000 rpm) and the supernatant was collected. Cell lysates were incubated with 1 M 1-215 for 1 hour at room temperature, then incubated with streptavidin-coupled agarose beads (ThermoFisher) overnight at 4 T. The beads were washed three times with lysis buffer and the bound proteins were boiled off the beads at 95 C for 5 minutes in 4X LDS Sample Buffer. The amount of BTK associated with the probe 1-215 was assessed by BTK western blot. All values were normalized to the DMSO-treated sample which is set to 100%. Figure 16 shows the western blot;
Figure 17 shows quantitation of Figure 16 demonstrating unoccupied BTK protein is available to the probe 1-215 when the cells have been exposed to low concentrations (10 nM, 1 nM) of 1-7 but at higher concentrations of 1-7 the BTK protein is fully occupied and cannot interact with I-215.
Washout Experiment with 1-7 and probe compound 1-215 [001417] Ramos cells were incubated with 0.1 M 1-7 or a reversible BTK
inhibitor control compound in serum free media for 1 hour at 37 C. The cells were then washed in compound-free media and lysed 0, 4, 6, or 8 hours after compound removal. Cell lysates were incubated with 1 M 1-215 for 1 hour at room temperature, then overnight at 4 C with streptavidin-coupled agarose beads. Protein was boiled off the beads and BTK association was assessed by western blot. Figure 18 shows the Western blot; Figure 19 shows the quantitation of Figure 18 and demonstrates all the BTK protein remains occupied by 1-7 for over 8 hours.
This suggests that the timeframe for re-synthesis of detectable BTK protein in Ramos cells is greater than 8 hours. In contrast, with the reversible inhibitor control, 45% of BTK protein is unbound and available to the probe at 0 hours and by 4 hours 100% of BTK protein is unbound and available to bind the probe. All samples were normalized to the DMSO-treated cells harvested at 0 hours.
Measuring BTK occupancy from in vitro samples by ELISA
[001418] In order to determine the amount of free B'TK in cell or tissue lysates, an ELISA
protocol was employed that utilizes a biotinylated probe compound that binds only to free, unoccupied BTK. The conjugated biotin is captured on a streptavidin-coated ELISA plate and detected with a mouse anti-BTK antibody (Becton Dickinson, Franklin Lakes, NJ, USA) and a secondary goat anti-mouse HRP antibody (Zymed, South San Francisco, CA, USA).
[001419] All samples were prepared with equal concentrations of Biorad lysis buffer (Hercules, CA, USA), 0.5% bovine serum albumin in PBS with 0.05% Tween-20 to give a final concentration of 1 M 1-215. Samples were incubated in a mixing plate for 1 hr at room temperature while shaking to allow probe compound 1-215 to bind to free BTK.
After incubation with 1-215, samples were added to a washed, streptavidin-coated ELISA plate (Pierce, Rockford, IL, USA) and incubated for 1 hr at room temperature while shaking. The plate was then washed with PBS containing 0.05% Tween-20 using an automatic plate washer. Anti-BTK
antibody was prepared at 1 : 1000 dilution in 0.5% BSA in PBS (0.05% Tween-20) and added to the ELISA
plate. The plate was incubated for 1 hr at room temperature while shaking. The plate was washed as described above and the secondary HRP antibody was prepared at 1 : 5000 dilution in 0.5%
BSA in PBS (0.05% Tween-20). The plate was incubated and washed as described above. TMB
was added to the plate, and OD650 was monitored until reaching 1 OD unit. The reaction was then stopped with addition of H2SO4. The plate was analyzed using Gen 5 software, and a 4 Parameter Logistic curve was employed to quantitate samples. Recombinant BTK
(Invitrogen, Carlsbad, CA, USA) was used for the standard curve.
[0014201 Table 19 shows results with Ramos cells reported as concentration at which >50%
or >90% of BTK is occupied. A concentration designated as "A" is greater than 1 nM; a concentration designated as "B" is greater than 10 nM; and a concentration designated as "C" is greater than 50 nM.

Compound # >50% occupancy >90% occupancy Human primary B cell covalent probe occupancy in vitro [0014211 Human primary B cells were isolated as described in Example 256, then resuspended in RPMI media (10% serum). The compound to be analyzed was added at a 1:1000 dilution to media. Cells were incubated with compound in a tissue culture incubator for 1 h at 37 T. After incubation, the cells were pelleted, washed with 1X PBS, and lysed on ice for 45 min with occasional agitation. Samples were spun in a chilled microcentrifuge for 30 min at 14,000 rpm and the supernatant was isolated. The supernatant was analyzed as described in Example 283 using I-215. 1-96 and 1-182 occupied at least 50% of BTK at concentrations greater than 10 nM.
Dog primary B cell covalent probe occupancy in vitro [0014221 Canine whole blood (30 mL) was diluted to 50 mL total with 1X PBS and layered on top of Histopaque- 1077 (Sigma Aldrich). The whole blood-Histopaque was spun at 400 x g for 30 min in a Beckman centrifuge with no brake. Peripheral blood mononuclear cells (PBMCs) were collected and pelleted at 400 x g for 15 min. Red blood cells (RBCs) were lysed with 2.5 mL RBC lysis buffer (Boston Bioproducts) and the remaining PBMCs were washed 3 times in 1X PBS at 250 x g. PBMCs were treated with compound at a 1:1000 dilution for one hour at 37 C, washed with PBS and lysed on ice for 45 minutes. The lysate was centrifuged for 30 minutes at 14,000 x g and the supernatant collected. The supernatant was analyzed as described in Example 283 using 1-215. 1-96 occupied at least 50% of BTK at concentrations greater than 10 nM.
Measuring BTK occupancy from in vivo samples by ELISA
[0014231 Rats were dosed orally with 30 mg/kg of compound and spleens were harvested either 2 or 24 hours after compound treatment. Rat spleens were disrupted between two microscope slides coated with frosted glass to recover single cell suspensions. Red blood cells were lysed by incubating with RBC lysis buffer (Boston BioProducts) for 2 minutes at room temperature, the cells were then resuspended in RPMI complete media and pelleted by centrifugation. Rat B cells were isolated by positive selection with B220+
antibody-magnetic bead conjugates, purified by MACS column and lysed in Bio-Rad lysis buffer at a concentration of 10 million cells/ 100 l. Lysates were analyzed employing the biotinylated probe compound I-215 in an ELISA protocol as described in detail in Example 278. Table 20 shows the results.

Omnia Assay Protocol for Potency Assessment Against BTK
[001358] Below describes the protocol using EGFR-WT and EGFR-T790M/L858R and the protocol BTK-optimized reagent conditions then follow.
[001359] The mechanics of the assay platform are best described by the vendor (Invitrogen, Carlsbad, CA) on their website at the following URL:
www.invitrogen.com/content.cfin?pageid-l 1338 or www.invitrogen.com/site/uslen/home/Products-and-Services/Applications/Drug-Discovery/Target-and-Lead-Identification-and-Validation/KinaseBiology/KB-Misc/Biochemical-Assays/Omnia-Kinase-Assays.html.
[001360] Briefly, lOX stocks of EGFR-WT (PV3872) from Invitrogen and EGFR-T790M/L858R (40350) from BPS Bioscience, San Diego, CA, 1.13X ATP (ASOO1A) and appropriate Tyr-Sox conjugated peptide substrates (KCZ1001) were prepared in 1X kinase reaction buffer consisting of 20 mM Tris, pH 7.5, 5 mM MgC12, 1 mM EGTA, 5 mM
(3-glycerophosphate, 5% glycerol (lOX stock, KBO02A) and 0.2 mM DTT (DSOO1A). 5 L of each enzyme were pre-incubated in a Coming (#3574) 384-well, white, non-binding surface microtiter plate (Corning, NY) for 30 min. at 27 C with a 0.5 L volume of 50%
DMSO and serially diluted compounds prepared in 50% DMSO. Kinase reactions were started with the addition of 45 L of the ATP/Tyr-Sox peptide substrate mix and monitored every 30-90 seconds for 60 minutes at &ex360/&em485 in a Synergy4 plate reader from BioTek (Winooski, VT). At the conclusion of each assay, progress curves from each well were examined for linear reaction kinetics and fit statistics (R2, 95% confidence interval, absolute sum of squares). Initial velocity (0 minutes to -30 minutes) from each reaction was determined from the slope of a plot of relative fluorescence units vs time (minutes) and then plotted against inhibitor concentration to estimate IC50 from log[Inhibitor] vs Response, Variable Slope model in GraphPad Prism from GraphPad Software (San Diego, CA).
[0013611 The modified BTK-optimized reagent conditions for the above protocol are:
[BTK] - 5 nM, [ATP] - 40 mM, [Y5-Sox] - 10 mM (ATP KMapp - 36 mM).

Cells were then stimulated with 1 g of goat F(ab')2 Anti-Human IgM and incubated on ice for 10 minutes to activate B cell receptor signaling pathways. After 10 minutes, the cells were washed once with PBS and then lysed on ice with Invitrogen Cell Extraction buffer. 16 g total protein from lysates were loaded on gel and blots were probed for phosphorylation of the BTK substrate PLC72. Dose response inhibition of BTK signaling in Ramos cells is depicted in Figures 1, 2, 3, 4 and 5.

Table 7. BTK Ramos Cellular Inhibition Data Compound # BTK Inhibition Compound # BTK Inhibition Compound # BTK Inhibition Washout Experiment with Ramos cells [001365] Ramos cells were serum starved for one hour in RPMI media +l%
glutamine at 37 C. After starvation, Ramos cells were treated with 100nM compound diluted in serum free RPMI media for 1 hour. After compound treatment, the media was removed and cells were washed with compound-free media. Subsequently, Ramos cells were washed every 2 hours and resuspended in fresh compound-free media. Cells were collected at specified timepoints, treated with lug anti-human IgM (Southern Biotech cat # 2022-01) for 10 minutes on ice to induce BCR
signaling and then washed in PBS. Ramos cells were then lysed in Cell Extraction Buffer (Invitrogen FNNOO11) supplemented with Roche complete protease inhibitor tablets (Roche 11697498001) and phosphatase inhibitors (Roche 04 906 837 001) and l8ug total protein lysate was loaded in each lane. Inhibition of BTK kinase activity was assayed by measuring its substrate (PLCy2) phosphorylation by western blot with phospho-specific antibodies from Cell Signaling Technologies cat# 3871. The results of this experiment with compounds 1-2, 1-4 and I-7 are depicted in Figures 1, 2 and 3.

[001367] Intact BTK was incubated for 1 hr at a l OX fold excess of 1-7 to protein. Aliquots (2 l) of the samples were diluted with 10 l of 0.1 % TFA prior to micro C4 ZipTipping directly onto the MALDI target using Sinapinic acid as the desorption matrix (10 mg/ml in 0.1%
TFA:Acetonitrile 20:80). See Figure 15. Top panel shows the mass spec trace of the intact BTK
protein (m/z 81,032 Da). The bottom panel shows mass spec trace when BTK was incubated with 1-7 (mw=345.4). The centroid mass (m/z= 81,403 Da) shows a positive shift of about 371.1 Da indicating complete modification of BTK by 1-7. Other compounds that completely modify BTK include 1-96, 1-71, 1-149, 1-161, 1-163, 1-182, 1-195, 1-207, 1-219, and 1-244.
Human primary B cell proliferation assay [0013681 Human naive B cells were purified from 100 mL whole blood using a MACS
purification kit designed to isolate CD19+, IgD+ cells by negative selection.
Purified naive B
cells were resuspended in RPMI complete and stimulated with 5 g/ml a-IgM for 72 hours. 3H-Thymidine was included in the culture media for the final 16h, cells were harvested and 3H
incorporation measured. Inhibition of B cell proliferation correlates with inhibition of BTK
substrate phosphorylation after a-IgM stimulation. Importantly, a molecule with the same scaffold as 1-7 but biochemically inactive against BTK, IR-7, is not active in the naive B cell proliferation assay.

A control sample (45 pmols) was also prepared which did not have the addition of (1-2). For tryptic digests a 5ul aliquot (7.5 pmols) was diluted with 15 ul of 0.1%
TFA prior to micro C18 Zip Tipping directly onto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as the matrix (5mg/ml in 0.1% TFA:Acetonitrile 50:50).
[0013741 As depicted in Figure 6, the expected peptide (GCLLNFLR) to be modified was immediately evident after reaction with 1-2 (MI mass of 359.17 Da) at MH+ of 1294.72. The peptide was also quite evident in the control sample as modified by lodacetamide at MH+ of 992.56. Interestingly the iodoacetamide modified peptide was not evident in the digest reacted with compound 1-2 indicating that the reaction was complete. There was no evidence of other modified peptides.
[001375] Evidence of compound 1-2 was observed at MH+ of 360.17 in the low mass range of the spectra. The fragmentation spectra of the 360.17 peak did show diagnostic fragments that were apparent in the PSD spectra of the modified peptide at 1294.72 (See Figure 6).
[001376] To further verify the presence of the modified peptides, both the iodoacetamide labeled (992.56) and 1-2 labeled (1294.72) were subjected to PSD (MS/MS) analsysis. After a database search of the NCBI nr Homo sapien database using Mascot MS/MS Ion Search program the top match was the expected peptide in both cases.
Instrumental:
[001377] For tryptic digests the instrument was set in Reflectron mode with a pulsed extraction setting of 2200. Calibration was done using the Laser Biolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20). For CID/PSD analysis the peptide was selected using cursors to set ion gate timing and fragmentation occurred at a laser power about 20%
higher and He was used as the collision gas for CID. Calibration for fragments was done using the P 14R fragmentation calibration for the Curved field Reflectron.
Mass Spectrometry for TEC Kinase (Compound 1-4) [001378] TEC kinase (45 pmols; Invitrogen) was incubated with (1-4) (450 pmols) for 3hrs at lOX excess prior to tryptic digestion. lodoacetamide was used as the alkylating agent after compound incubation. A control sample (45 pmols) was also prepared which did not have the addition of (1-4). For tryptic digests a 5ul aliquot (7.5 pmols) was diluted with 15 ul of 0.1%
TFA prior to micro C18 Zip Tipping directly onto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as the matrix (5mg/ml in 0.1%TFA:Acetonitrile 50:50).
[001379] As depicted in Figure 7, the expected peptide (GCLLNFLR) to be modified was immediately evident at MH+ of 1355.72. This is the mass to be expected when compound 1-4, with an adduct mass of 420.21, is added to the peptide mass of 935.51. The peptide was also quite evident in the control sample as modified by lodacetamide at MH+ of 992.56.
Interestingly the iodoacetamide modified peptide was not evident in the digest reacted with compound 1-4 indicating that the reaction was complete. There was no evidence of other modified peptides.
[001380] Evidence of compound 1-4 was observed at MH+ of 421.35 in the low mass range of the spectra. The fragmentation spectra of the 421.35 peak did reveal two prominent peaks that were apparent in the PSD spectra of the modified peptide at 1355.72 (See Figure 7).
[001381] To further verify the presence of the modified peptide with compound 1-4, the peptide at MH+ of 1355.72 was subjected to PSD (MS/MS) analsysis. Because of the low intensity of fragments, a database correlation was not possible. However, diagnostic fragments from the 1-4 molecule itself provided confidnece in the identification.
Diagnostic fragments at MH+ of 376.38 and 421.83 are from I-4.
Instrumental: .
[001382] For tryptic digests the instrument was set in Reflectron mode with a pulsed extraction setting of 1800. Calibration was done using the Laser Biolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20). For CID/PSD analysis the peptide was selected using cursors to set ion gate timing and fragmentation occurred at a laser power about 20%
higher and He was used as the collision gas for CID. Calibration for fragments was done using the P 14R fragmentation calibration for the Curved field Reflectron.
Mass Spectrometry for TEC Kinase (Compound 1-7) [001383] TEC kinase (45 pmols; Invitrogen) was incubated with (1-7) (450 pmols) for 3hrs at lOX excess prior to tryptic digestion. lodoacetamide was used as the alkylating agent after compound incubation. A control sample (45 pmols) was also prepared which did not have the addition of (1-7). For tryptic digests a 5ul aliquot (7.5 pmols) was diluted with 15 ul of 0.1%
TFA prior to micro C18 Zip Tipping directly onto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as the matrix (5mg/ml in 0.l%TFA:Acetonitrile 50:50).
[001384] As depicted in Figure 8, the expected peptide (GCLLNFLR) to be modified was immediately evident at MH+ of 1280.73. This is the mass to be expected when compound 1-7, with an adduct mass of 345.16, is added to the peptide mass of 935.51. The peptide was also quite evident in the control sample as modified by lodacetamide at MH+ of 992.56.
Interestingly the iodoacetamide modified peptide was not evident in the digest reacted with compound 1-7 indicating that the reaction was complete. There was no evidence of any other modified peptide at MH+ of 1985.93 (TIDELVECEETFGR).
[001385] Evidence of compound 1-7 was observed at MH+ of 346.32 in the low mass range of the spectra. The fragmentation spectra of the 346.32 peak did show many diagnostic fragments that were apparent in the PSD spectra of the two modified peptides (See Figure 8).
[001386] To further verify the presence of the modified peptides with compound 1-7, the peptides at MH+ of 1280.73 and 1985.93 were subjected to PSD (MS/MS) analsysis. A
correlational analysis with the homosapien database identified the correct peptide modified by I-7.

Expression analysis was conducted in 125 ml culture of SF21 insect cells ((grown in SF9001 SFM (Invitrogen cat # 10902-088), supplemented with lOmg/L gentamicin (Invitrogen, Carlsbad, CA, cat# 15710-064)) using a viral load of 0.lml of virus per 100 ml of cell suspension. Expression was optimized using Blue Sky Biotech's Infection Kinetics Monitoring system (Worcester, MA).

Cell pellets were resuspended in Blue Sky Biotech's lysis buffer (Worcester, MA, 1X WX; solubilization buffer, containing a protease inhibitor cocktail of leupeptin, pepstatin, PMSF, aprotinin and EDTA) at a ratio of 10 ml per gram of wet cell paste.Cells were lysed by sonication and the lysate was clarified by centrifugation at 9,000 RPM for 30 minutes in a GSA rotor. 500 l bed volume of NiNTA resin (Qiagen, Valencia, CA) was added to the supernatants and batch bound for two hours with constant agitation. The material was transferred by gravity into an empty 2ml column. The column was washed with 2 ml of wash buffer (Blue Sky Biotech, Worcester, MA, lX WX, 25mM imidazole ).The protein was eluted with lX WX + imidazole at varying concentrations:
Elution 1: 75 mM imidazole (2 fractions, 1 column volume); Elution 2 : 150 mM
imidazole (2 fractions, 1 column volume); Elution 3 : 300 mM imidazole (2 fractions, 1 column volume). All the elution fractions were analyzed by SDS page followed by Coomassie staining and Western Blotting using anti-penta-his antibody (Qiagen, Valencia, CA). The carboxy-terminal six-histidine "tag" was removed from some of the purified protein using AcTEV
Protease kit ( Invitrogen, Carlsbad, CA, Cat# 12575-015), following manufacturer's instructions. All the samples (pre- and post- Tev cut) were analyzed by SDS page followed by Coomassie staining and Western Blotting, as described above.
Mass Spectrometry for EGFR
[001395] EGFR wild type and EGFR (mutant C797S) is incubated with 10-fold excess of test compound for 1 hr and 3 hrs. 1 l aliquots of the samples (total volume 5-8 ul) are diluted with 10 ul of 0.1 % TFA prior to micro C4 ZipTipping directly onto the MALDI
target using Sinapinic acid as the desorption matrix (10 mg/ml in 0.1%TFA:Acetonitrile 50:50). Intact mass measurement reveals that the wild type has a nominal mass of about 37557 and the mutant slightly lower at 37500. Reactivity is only observed for the wild type EGFR
with a new peak appearing at a mass consistent with a single site covalent modification with test compound which has a mass of 410 Da.

Natl.
Acad. Sci. USA Vol 95, pp 12022-12027, 1998. Specifically, A431 human epidermoid carcinoma cells were grown in 6-well plates to 90% confluence and then incubated in serum-free media for 18 hr. Duplicate sets of cells were treated with 1 M designated compound for 2, 5, 10, 30, or 60 min. Cells were washed free of the compound with warmed serum-free medium, incubated for 2 hr, washed again, incubated another 2 hr, washed again, and then incubated another 2 hr washed again and incubated for additional 2 hr and then stimulated with 100 ng/ml EGF for 5 min.

[0014001 Compounds were assayed in A431 human epidermoid carcinoma cells using a method substantially similar to that described in Fry, et al. Specifically, A431 human epidermoid carcinoma cells were grown in 6-well plates to 90% confluence and then incubated in serum-free media for 18 hr. Cells were then treated with 10, 1, 0.1, 0.01, or 0.001 M test compound for 1 hr. Cells were then stimulated with 100 ng/ml EGF for 5 min, and extracts were made as described in Fry, et al. 20ug total protein from lysates were loaded on gel and blots were probed for either EGFR phosphorylation or p42/p44 Erk phosphorylation.
Washout Experiment for EGFR Activity [0014011 A431 human epidermoid carcinoma cells were grown in 6-well plates to '90%
confluence and then incubated in serum-free media for 18 hr. Duplicate sets of cells were treated with 1 M designated compound for 1 hr. One set of cells was then stimulated with 100 ng/ml EGF for 5 min, and extracts were made as described. The other set of cells was washed free of compound 1-7 with warmed compound-free medium, incubated for 2 hr, washed again, incubated another 2 hr, washed again, and then incubated another 2 hr washed again and incubated for additional 2 hr and then stimulated with EGF. The results of this experiment with compound 1-7 are depicted in Figure 10.
Washout Experiment in HCC827 cells containing EGFR deletion mutantHCC827 [0014021 Cells (ATCC, Manassas,VA) were plated in Growth Media (RPMI 1640) supplemented with 10% FBS,10uM HEPES, 2mM 1-glutamine, 1mM NaPyruvate and pen/strep (Invitrogen, Carlsbad, CA) at a density of 2.5 x 10 5 cells per well in 6 well tissue culture plates.
Twenty four hours later the cells were washed 2 x with PBS then serum starved overnight in Basal Media (Growth Media without FBS).
[0014031 The following morning the media was removed and 2 ml fresh Basal Media containing luM compound in 0.1% DMSO was added to duplicate wells. At 1 hour, one well of cells was treated with 100 ng/ml of EGF for 5 minutes, rinsed with PBS, then lysed by scraping into 75 ul of Cell Extraction Buffer (Invitrogen, Carlsbad, CA) plus PhosSTOP
Phosphatase Inhibitor and Complete Protease Inhibitor (Roche, Indianapolis, IN) for the Oh time point. The compound was removed from the second set of wells and they were washed 2X with Basal Media. The cells were washed with Basal Media every 2 hours until 8 hours when they were treated with EGF and lysed as at the 0 h time point.
[0014041 Lysate protein concentrations were determined by BCA Assay (Pierce, Rockford, IL) and 10 ug of each lysate was separated by 4-12% gradient SDS-PAGE
(Invitrogen), transferred to Immobilon-FL membrane (Millipore) and probed with rabbit anti-Phospho-EGFR
(Tyr1068) (Zymed-now Invitrogen) and mouse anti-EGFR (Cell Signaling Technologies, Danvers, MA) antibodies. Phospho-protein signals were quantitated using Odyssey Infrared Imagning (Li-Cor Biosciences, Lincoln, Nebraska). The results of this experiment are depicted in Figure 9 where it shows compound 1-2 compared to results of compound 1-4 and compound I-7 in the same "washout" experiment.
Mass Spectrometry for ERBB4 [0014051 Erbb4 kinase domain (Upstate) was incubated with compound for 60 minutes at 10-fold excess of compound 1-4 and I-11 to protein. 1 l aliquots of the samples (total volume of 4.24u1) were diluted with 10 l of 0.1 % TFA prior to micro C4 ZipTipping directly onto the MALDI target using Sinapinic acid as the desorption matrix (10 mg/ml in 0.1%TFA:Acetonitrile 50:50). For intact protein mass measurement the instrument was set in Linear mode using a pulsed extraction setting of 16,952 for the myoglobin standard used to calibrate the instrument (Shimadzu Axima TOF2).
[0014061 Intact ErbB4 protein occurs at MH+ of 35850 with corresponding sinapinic (matrix) adducts occurring about 200 Da higher. A stochiometric incorporation of the test compound (1-4 and I-11) (Mw of 410 Da) produced a new mass peak which is approximately 410 Da higher (MH+ of 36260). This is consistent with covalent modification of ErbB4 with compounds 1-4 and I-11.
ErbB1, ErbB2 and/or ErbB4 Kinase Inhibition [0014071 Compounds of the present invention were assayed as inhibitors of one or more of ErbB 1, ErbB2, and/or ErbB4 in a manner substantially similar to the method described by Invitrogen Corp (Invitrogen Corporation, 1600 Faraday Avenue, Carlsbad, California, CA;
http://www.invitrogen.com/downloads/Z-LYTE_Brochure_1205.pdf) using the Z'-LYTETM
biochemical assay procedure or similar biochemical assay. The Z'-LYTETM
biochemical assay employs a fluorescence-based, coupled-enzyme format and is based on the differential sensitivity of phosphorylated and non-phosphorylated peptides to proteolytic cleavage.
Using this assay, Compound 1-56 was found to inhibit ERBB1 with an IC50 of 2,233 nM. Using this assay, Compound 1-56 was found to inhibit ERBB4 (HER4) with an ICso of 2,165 nM.
Mass Spectrometry for Janus-3 Kinase (JAK3) [0014081 JAK3 kinase (33 pmols; Invitrogen) was incubated with (1-7) (327 pmols) for 3hrs at lOX excess prior to tryptic digestion. Iodoacetamide was used as the alkylating agent after compound incubation. For tryptic digests a 5ul aliquot (5.5 pmols) was diluted with 15 ul of 0.1% TFA prior to micro C18 Zip Tipping directly onto the MALDI target using alpha cyano-4-hydroxy cinnamic acid as the matrix (5mg/ml in 0.1%TFA:Acetonitrile 50:50).
[001409] As depicted in Figure 11, the expected peptide (LVMEYLPSGCLR) to be modified was immediately evident as the largest peak at MH+ of 1725.88. This is the mass to be expected when compound 1-7, with an adduct mass of 345.16, is added to the peptide mass of 1380.70. Interestingly the iodoacetamide modified peptide was not evident at MH+ of 1437.73 in the digest reacted with compound 1-7 indicating that the reaction was not entirely complete.
There was also evidence for a number of other modified peptides, however, their signals were low.
[001410] Evidence of compound 1-7 was observed at MH+ of 346.12 in the low mass range of the spectra. The fragmentation spectra of the 346.12 peak did not show diagnostic fragments that were apparent in the PSD spectra of the modified peptides (See Figure 11).
[001411] To further verify the presence of the modified peptides with compound 1-7, the peptides at MH+ of 1725.88 and 1118.55 were subjected to PSD (MS/MS) analsysis. A
correlational analysis with the homosapien database identified the correct peptides as being modified by 1-7. Compound I-11 was also tested using the same procedure and showed measurable modification.
Instrumental:
[001412] For tryptic digests the instrument was set in Reflectron mode with a pulsed extraction setting of 2200. Calibration was done using the Laser Biolabs Pep Mix standard (1046.54, 1296.69, 1672.92, 2093.09, 2465.20). For CID/PSD analysis the peptide was selected using cursors to set ion gate timing and fragmentation occurred at a laser power about 20%
higher and He was used as the collision gas for CID. Calibration for fragments was done using the P 14R fragmentation calibration for the Curved field Reflectron.
Omnia Assay Protocol for Potency Assessment Against the Active Form of JAK3:
[001413] The Omnia Assay Protocol for potency assessment against JAK3 was performed in a substantially similar manner as that described in Example 251 above except that the modified JAK3-optimized reagent conditions were:
[JAK3] - 5 nM, [ATP] - 5 M, [Y12-Sox] - 5 M (ATP KMapp -5 M).
[001414] Table 18 shows the activity of selected compounds of this invention in the JAK3 inhibition assay. The compound numbers correspond to the compound numbers in Table 5.
Compounds having an activity designated as "A" provided an IC50 <10 nM;
compounds having an activity designated as "B" provided an IC50 10-100 nM; compounds having an activity designated as "C" provided an ICso of 100-1000 nM; compounds having an activity designated as "D" provided an IC50 of 1000-10,000 nM; and compounds having an activity designated as "E" provided an IC50 >10,000 nM.

CTLL2: murine lymphoma cell line ATCC: TIB-214. 5x106 cells/sample were IL-2 starved in RPMI-1640 media for 2 hours. Designated samples were then treated with compound for 90 minutes. Samples, except DMSO control were then stimulated with I OOnM IL-2 for 10 minutes.
Samples were lysed and subjected to Western Analysis. The results are displayed in Figure 12, Figure 13 and Figure 14.
BTK occupancy in Ramos cells with 1-7 and 1-215 using streptavidin beads [0014161 Ramos cells were incubated with 0.1, 0.05, 0.01, or 0.001 pM 1-7 in serum free media for 1 hour at 37 T. The cells were pelleted by centrifugation and lysed in Cell Extraction buffer (Invitrogen) for 10 minutes on ice, centrifuged (10 minutes at 14,000 rpm) and the supernatant was collected. Cell lysates were incubated with 1 M 1-215 for 1 hour at room temperature, then incubated with streptavidin-coupled agarose beads (ThermoFisher) overnight at 4 T. The beads were washed three times with lysis buffer and the bound proteins were boiled off the beads at 95 C for 5 minutes in 4X LDS Sample Buffer. The amount of BTK associated with the probe 1-215 was assessed by BTK western blot. All values were normalized to the DMSO-treated sample which is set to 100%. Figure 16 shows the western blot;
Figure 17 shows quantitation of Figure 16 demonstrating unoccupied BTK protein is available to the probe 1-215 when the cells have been exposed to low concentrations (10 nM, 1 nM) of 1-7 but at higher concentrations of 1-7 the BTK protein is fully occupied and cannot interact with I-215.
Washout Experiment with 1-7 and probe compound 1-215 [001417] Ramos cells were incubated with 0.1 M 1-7 or a reversible BTK
inhibitor control compound in serum free media for 1 hour at 37 C. The cells were then washed in compound-free media and lysed 0, 4, 6, or 8 hours after compound removal. Cell lysates were incubated with 1 M 1-215 for 1 hour at room temperature, then overnight at 4 C with streptavidin-coupled agarose beads. Protein was boiled off the beads and BTK association was assessed by western blot. Figure 18 shows the Western blot; Figure 19 shows the quantitation of Figure 18 and demonstrates all the BTK protein remains occupied by 1-7 for over 8 hours.
This suggests that the timeframe for re-synthesis of detectable BTK protein in Ramos cells is greater than 8 hours. In contrast, with the reversible inhibitor control, 45% of BTK protein is unbound and available to the probe at 0 hours and by 4 hours 100% of BTK protein is unbound and available to bind the probe. All samples were normalized to the DMSO-treated cells harvested at 0 hours.
Measuring BTK occupancy from in vitro samples by ELISA
[001418] In order to determine the amount of free B'TK in cell or tissue lysates, an ELISA
protocol was employed that utilizes a biotinylated probe compound that binds only to free, unoccupied BTK. The conjugated biotin is captured on a streptavidin-coated ELISA plate and detected with a mouse anti-BTK antibody (Becton Dickinson, Franklin Lakes, NJ, USA) and a secondary goat anti-mouse HRP antibody (Zymed, South San Francisco, CA, USA).
[001419] All samples were prepared with equal concentrations of Biorad lysis buffer (Hercules, CA, USA), 0.5% bovine serum albumin in PBS with 0.05% Tween-20 to give a final concentration of 1 M 1-215. Samples were incubated in a mixing plate for 1 hr at room temperature while shaking to allow probe compound 1-215 to bind to free BTK.
After incubation with 1-215, samples were added to a washed, streptavidin-coated ELISA plate (Pierce, Rockford, IL, USA) and incubated for 1 hr at room temperature while shaking. The plate was then washed with PBS containing 0.05% Tween-20 using an automatic plate washer. Anti-BTK
antibody was prepared at 1 : 1000 dilution in 0.5% BSA in PBS (0.05% Tween-20) and added to the ELISA
plate. The plate was incubated for 1 hr at room temperature while shaking. The plate was washed as described above and the secondary HRP antibody was prepared at 1 : 5000 dilution in 0.5%
BSA in PBS (0.05% Tween-20). The plate was incubated and washed as described above. TMB
was added to the plate, and OD650 was monitored until reaching 1 OD unit. The reaction was then stopped with addition of H2SO4. The plate was analyzed using Gen 5 software, and a 4 Parameter Logistic curve was employed to quantitate samples. Recombinant BTK
(Invitrogen, Carlsbad, CA, USA) was used for the standard curve.
[0014201 Table 19 shows results with Ramos cells reported as concentration at which >50%
or >90% of BTK is occupied. A concentration designated as "A" is greater than 1 nM; a concentration designated as "B" is greater than 10 nM; and a concentration designated as "C" is greater than 50 nM.

The compound to be analyzed was added at a 1:1000 dilution to media. Cells were incubated with compound in a tissue culture incubator for 1 h at 37 T. After incubation, the cells were pelleted, washed with 1X PBS, and lysed on ice for 45 min with occasional agitation. Samples were spun in a chilled microcentrifuge for 30 min at 14,000 rpm and the supernatant was isolated. The supernatant was analyzed as described in Example 283 using I-215. 1-96 and 1-182 occupied at least 50% of BTK at concentrations greater than 10 nM.
Dog primary B cell covalent probe occupancy in vitro [0014221 Canine whole blood (30 mL) was diluted to 50 mL total with 1X PBS and layered on top of Histopaque- 1077 (Sigma Aldrich). The whole blood-Histopaque was spun at 400 x g for 30 min in a Beckman centrifuge with no brake. Peripheral blood mononuclear cells (PBMCs) were collected and pelleted at 400 x g for 15 min. Red blood cells (RBCs) were lysed with 2.5 mL RBC lysis buffer (Boston Bioproducts) and the remaining PBMCs were washed 3 times in 1X PBS at 250 x g. PBMCs were treated with compound at a 1:1000 dilution for one hour at 37 C, washed with PBS and lysed on ice for 45 minutes. The lysate was centrifuged for 30 minutes at 14,000 x g and the supernatant collected. The supernatant was analyzed as described in Example 283 using 1-215. 1-96 occupied at least 50% of BTK at concentrations greater than 10 nM.
Measuring BTK occupancy from in vivo samples by ELISA
[0014231 Rats were dosed orally with 30 mg/kg of compound and spleens were harvested either 2 or 24 hours after compound treatment. Rat spleens were disrupted between two microscope slides coated with frosted glass to recover single cell suspensions. Red blood cells were lysed by incubating with RBC lysis buffer (Boston BioProducts) for 2 minutes at room temperature, the cells were then resuspended in RPMI complete media and pelleted by centrifugation. Rat B cells were isolated by positive selection with B220+
antibody-magnetic bead conjugates, purified by MACS column and lysed in Bio-Rad lysis buffer at a concentration of 10 million cells/ 100 l. Lysates were analyzed employing the biotinylated probe compound I-215 in an ELISA protocol as described in detail in Example 278. Table 20 shows the results.
