Definitions

  • Protein kinase inhibitors, regulators or modulators alter the function of kinases such as Akt kinases, Checkpoint (CHK) kinases (e.g., CHK-1, CHK-2 etc.), Aurora kinases, Pim kinases (e.g., Pim-1, Pim-2, Pim-3 etc.), tyrosine kinases and the like.
  • CHK Checkpoint
  • Pim kinases
  • Pim kinases e.g., Pim-1, Pim-2, Pim-3 etc.
  • tyrosine kinases and the like.
  • Tyrosine kinases can be of the receptor type (having extracellular, transmembrane and intracellular domains) or the non-receptor type (being wholly intracellular).
  • Receptor-type tyrosine kinases are comprised of a large number of transmembrane receptors with diverse biological activity. In fact, about 20 different subfamilies of receptor-type tyrosine kinases have been identified.
  • One tyrosine kinase subfamily, designated the HER subfamily is comprised of EGFR (HER1), HER2, HER3 and HER4.
  • Ligands of this subfamily of receptors identified so far include epithelial growth factor, TGF-alpha, amphiregulin, HB-EGF, betacellulin and heregulin.
  • Another subfamily of these receptor-type tyrosine kinases is the insulin subfamily, which includes INS-R, IGF-IR, IR, and IR-R.
  • the PDGF subfamily includes the PDGF-alpha and beta receptors, CSFIR, c-kit and FLK-II.
  • the FLK family is comprised of the kinase insert domain receptor (KDR), fetal liver kinase-1 (FLK-1), fetal liver kinase-4 (FLK-4) and the fms-like tyrosine kinase-1 (flt-1).
  • KDR kinase insert domain receptor
  • FLK-1 fetal liver kinase-1
  • FLK-4 fetal liver kinase-4
  • flt-1 fms-like tyrosine kinase-1
  • At least one of the non-receptor protein tyrosine kinases is believed to mediate the transduction in T-cells of a signal from the interaction of a cell-surface protein (Cd4) with a cross-linked anti-Cd4 antibody.
  • Cd4 cell-surface protein
  • the non-receptor type of tyrosine kinases is also comprised of numerous subfamilies, including Src, Frk, Btk, Csk, Abl, Zap70, Fes/Fps, Fak, Jak, Ack, and LIMK.
  • Src subfamily is one of the largest and includes Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr, and Yrk.
  • Src subfamily of enzymes has been linked to oncogenesis.
  • Protein kinases which have been shown to be involved in the angiogenic process include three members of the growth factor receptor tyrosine kinase family; VEGF-R2 (vascular endothelial growth factor receptor 2, also known as KDR (kinase insert domain receptor) and as FLK 1); FGF-R (fibroblast growth factor receptor); and TEK (also known as Tie-2).
  • VEGF-R2 vascular endothelial growth factor receptor 2, also known as KDR (kinase insert domain receptor) and as FLK 1
  • FGF-R fibroblast growth factor receptor
  • TEK also known as Tie-2
  • FGFR binds the angiogenic growth factors aFGF and bFGF and mediates subsequent intracellular signal transduction.
  • growth factors such as bFGF may play a critical role in inducing angiogenesis in solid tumors that have reached a certain size.
  • bFGF growth factors
  • FGF-R is expressed in a number of different cell types throughout the body and may or may not play important roles in other normal physiological processes in the adult. Nonetheless, systemic administration of a small molecule inhibitor of the kinase activity of FGF-R has been reported to block bFGF-induced angiogenesis in mice without apparent toxicity. Mohammad et al., EMBO Journal, 17, 5996-5904 (1998).
  • TEK also known as Tie-2
  • Tie-2 is another receptor tyrosine kinase expressed only on endothelial cells which has been shown to play a role in angiogenesis.
  • the binding of the factor angiopoietin-1 results in autophosphorylation of the kinase domain of TEK and results in a signal transduction process which appears to mediate the interaction of endothelial cells with peri-endothelial support cells, thereby facilitating the maturation of newly formed blood vessels.
  • the factor angiopoietin-2 appears to antagonize the action of angiopoietin-1 on TEK and disrupts angiogenesis. Maisonpierre et al., Science, 277, 55-60 (1997).
  • Pim-1 is a small serine/threonine kinase. Elevated expression levels of Pim-1 have been detected in lymphoid and myeloid malignancies, and recently Pim-1 was identified as a prognostic marker in prostate cancer.
  • K. Peltola “Signaling in Cancer: Pim-1 Kinase and its Partners”, Annales Universitatis Turkuensis, Sarja-Ser. D Osa-Tom. 616, (Aug. 30, 2005), http://kirjasto.utu.fi/julkaisupalvelut/annaalit/2004/D616.html.

Abstract

The present invention provides methods for inhibiting protein kinases selected from the group consisting of AKT, Checkpoint kinase, Aurora kinase, Pim kinases, and tyrosine kinase using pyrazolo[1,5-a]pyrimidine compounds and methods of treatment, prevention, inhibition, or amelioration of one or more diseases associated with protein kinases using such compounds.

Description

  • This application claims the benefit of priority from U.S. Provisional Patent Application Ser. No. 60/724,158, filed on Oct. 6, 2005.
    • FIELD OF THE INVENTION
  • The present invention relates to methods for inhibiting, regulating or modulating Akt kinases, Checkpoint kinases, Aurora kinases, Pim kinases, and/or tyrosine kinases using pyrazolo[1,5-a]pyrimidine compounds or pharmaceutical compositions containing the compounds, and methods of treatment using the compounds or compositions to treat diseases such as, for example, cancer, inflammation, arthritis, viral diseases, neurodegenerative diseases such as Alzheimer's disease, cardiovascular diseases, and fungal diseases.
    • BACKGROUND OF THE INVENTION
  • Protein kinases are a family of enzymes that catalyze phosphorylation of proteins, in particular the hydroxyl group of specific tyrosine, serine, or threonine residues in proteins. Protein kinases are pivotal in the regulation of a wide variety of cellular processes, including metabolism, cell proliferation, cell differentiation, and cell survival. Uncontrolled proliferation is a hallmark of cancer cells, and can be manifested by a deregulation of the cell division cycle in one of two ways—making stimulatory genes hyperactive or inhibitory genes inactive. Protein kinase inhibitors, regulators or modulators alter the function of kinases such as Akt kinases, Checkpoint (CHK) kinases (e.g., CHK-1, CHK-2 etc.), Aurora kinases, Pim kinases (e.g., Pim-1, Pim-2, Pim-3 etc.), tyrosine kinases and the like.
  • Checkpoint kinases prevent cell cycle progression at inappropriate times, such as in response to DNA damage, and maintain the metabolic balance of cells while the cell is arrested, and in some instances can induce apoptosis (programmed cell death) when the requirements of the checkpoint have not been met. Checkpoint control can occur in the G1 phase (prior to DNA synthesis) and in G2, prior to entry into mitosis.
  • One series of checkpoints monitors the integrity of the genome and, upon sensing DNA damage, these “DNA damage checkpoints” block cell cycle progression in G1 & G2 phases, and slow progression through S phase. This action enables DNA repair processes to complete their tasks before replication of the genome and subsequent separation of this genetic material into new daughter cells takes place. Inactivation of CHK1 has been shown to transduce signals from the DNA-damage sensory complex to inhibit activation of the cyclin B/Cdc2 kinase, which promotes mitotic entry, and abrogate G2 arrest induced by DNA damage inflicted by either anticancer agents or endogenous DNA damage, as well as result in preferential killing of the resulting checkpoint defective cells. See, e.g., Peng et al., Science, 277, 1501-1505 (1997); Sanchez et al., Science, 277, 1497-1501 (1997), Nurse, Cell, 91, 865-867 (1997); Weinert, Science, 277, 1450-1451 (1997); Walworth et al., Nature, 363, 368-371 (1993); and Al-Khodairy et al., Molec. Biol. Cell., 5, 147-160 (1994).
  • Selective manipulation of checkpoint control in cancer cells could afford broad utilization in cancer chemotherapeutic and radiotherapy regimens and may, in addition, offer a common hallmark of human cancer “genomic instability” to be exploited as the selective basis for the destruction of cancer cells. A number of factors place CHK1 as a pivotal target in DNA-damage checkpoint control. The elucidation of inhibitors of this and functionally related kinases such as CDS1/CHK2, a kinase recently discovered to cooperate with CHK1 in regulating S phase progression (see Zeng et al., Nature, 395, 507-510 (1998); Matsuoka, Science, 282, 1893-1897 (1998)), could provide valuable new therapeutic entities for the treatment of cancer.
  • Another group of kinases are the tyrosine kinases. Tyrosine kinases can be of the receptor type (having extracellular, transmembrane and intracellular domains) or the non-receptor type (being wholly intracellular). Receptor-type tyrosine kinases are comprised of a large number of transmembrane receptors with diverse biological activity. In fact, about 20 different subfamilies of receptor-type tyrosine kinases have been identified. One tyrosine kinase subfamily, designated the HER subfamily, is comprised of EGFR (HER1), HER2, HER3 and HER4. Ligands of this subfamily of receptors identified so far include epithelial growth factor, TGF-alpha, amphiregulin, HB-EGF, betacellulin and heregulin. Another subfamily of these receptor-type tyrosine kinases is the insulin subfamily, which includes INS-R, IGF-IR, IR, and IR-R. The PDGF subfamily includes the PDGF-alpha and beta receptors, CSFIR, c-kit and FLK-II. The FLK family is comprised of the kinase insert domain receptor (KDR), fetal liver kinase-1 (FLK-1), fetal liver kinase-4 (FLK-4) and the fms-like tyrosine kinase-1 (flt-1). For detailed discussion of the receptor-type tyrosine kinases, see Plowman et al., DN&P 7(6): 334-339, 1994.
  • At least one of the non-receptor protein tyrosine kinases, namely, LCK, is believed to mediate the transduction in T-cells of a signal from the interaction of a cell-surface protein (Cd4) with a cross-linked anti-Cd4 antibody. A more detailed discussion of non-receptor tyrosine kinases is provided in Bolen, Oncogene, 8, 2025-2031 (1993). The non-receptor type of tyrosine kinases is also comprised of numerous subfamilies, including Src, Frk, Btk, Csk, Abl, Zap70, Fes/Fps, Fak, Jak, Ack, and LIMK. Each of these subfamilies is further sub-divided into varying receptors. For example, the Src subfamily is one of the largest and includes Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr, and Yrk. The Src subfamily of enzymes has been linked to oncogenesis. For a more detailed discussion of the non-receptor type of tyrosine kinases, see Bolen, Oncogene, 8:2025-2031 (1993).
  • In addition to its role in cell-cycle control, protein kinases also play a crucial role in angiogenesis, which is the mechanism by which new capillaries are formed from existing vessels. When required, the vascular system has the potential to generate new capillary networks in order to maintain the proper functioning of tissues and organs. In the adult, however, angiogenesis is fairly limited, occurring only in the process of wound healing and neovascularization of the endometrium during menstruation. On the other hand, unwanted angiogenesis is a hallmark of several diseases, such as retinopathies, psoriasis, rheumatoid arthritis, age-related macular degeneration, and cancer (solid tumors). Protein kinases which have been shown to be involved in the angiogenic process include three members of the growth factor receptor tyrosine kinase family; VEGF-R2 (vascular endothelial growth factor receptor 2, also known as KDR (kinase insert domain receptor) and as FLK 1); FGF-R (fibroblast growth factor receptor); and TEK (also known as Tie-2).
  • VEGF-R2, which is expressed only on endothelial cells, binds the potent angiogenic growth factor VEGF and mediates the subsequent signal transduction through activation of its intracellular kinase activity. Thus, it is expected that direct inhibition of the kinase activity of VEGF-R2 will result in the reduction of angiogenesis even in the presence of exogenous VEGF (see Strawn et al, Cancer Research, 56, 3540-3545 (1996)), as has been shown with mutants of VEGF-R2 which fail to mediate signal transduction. Millauer et al, Cancer Research, 56, 1615-1620 (1996). Furthermore, VEGF-R2 appears to have no function in the adult beyond that of mediating the angiogenic activity of VEGF. Therefore, a selective inhibitor of the kinase activity of VEGF-R2 would be expected to exhibit little toxicity.
  • Similarly, FGFR binds the angiogenic growth factors aFGF and bFGF and mediates subsequent intracellular signal transduction. Recently, it has been suggested that growth factors such as bFGF may play a critical role in inducing angiogenesis in solid tumors that have reached a certain size. Yoshiji et al., Cancer Research, 57, 3924-3928 (1997). Unlike VEGF-R2, however, FGF-R is expressed in a number of different cell types throughout the body and may or may not play important roles in other normal physiological processes in the adult. Nonetheless, systemic administration of a small molecule inhibitor of the kinase activity of FGF-R has been reported to block bFGF-induced angiogenesis in mice without apparent toxicity. Mohammad et al., EMBO Journal, 17, 5996-5904 (1998).
  • TEK (also known as Tie-2) is another receptor tyrosine kinase expressed only on endothelial cells which has been shown to play a role in angiogenesis. The binding of the factor angiopoietin-1 results in autophosphorylation of the kinase domain of TEK and results in a signal transduction process which appears to mediate the interaction of endothelial cells with peri-endothelial support cells, thereby facilitating the maturation of newly formed blood vessels. The factor angiopoietin-2, on the other hand, appears to antagonize the action of angiopoietin-1 on TEK and disrupts angiogenesis. Maisonpierre et al., Science, 277, 55-60 (1997).
  • Pim-1 is a small serine/threonine kinase. Elevated expression levels of Pim-1 have been detected in lymphoid and myeloid malignancies, and recently Pim-1 was identified as a prognostic marker in prostate cancer. K. Peltola, “Signaling in Cancer: Pim-1 Kinase and its Partners”, Annales Universitatis Turkuensis, Sarja-Ser. D Osa-Tom. 616, (Aug. 30, 2005), http://kirjasto.utu.fi/julkaisupalvelut/annaalit/2004/D616.html. Pim-1 acts as a cell survival factor and may prevent apoptosis in malignant cells. K. Petersen Shay et al., Molecular Cancer Research 3:170-181 (2005).

  • There is a need for methods to inhibit protein kinases to treat or prevent disease states associated with abnormal cell proliferation. Moreover, it is desirable for such methods to use kinase inhibitors that possess both high affinity for the target kinase as well as high selectivity versus other protein kinases. Useful small-molecule compounds that may be readily synthesized and are potent inhibitors of cell proliferation are those, for example, that are inhibitors of one or more protein kinases, such as Akt (e.g., Akt-1, Akt-2, Akt-3), CHK1, CHK2, VEGF (VEGF-R2), Aurora (e.g., Aurora-1, Aurora-2, Aurora-3 etc), Pim-1 and both receptor and non-receptor tyrosine kinases.
    • SUMMARY OF THE INVENTION
  • In its many embodiments, the present invention provides methods for inhibiting, regulating or modulating Akt kinases, Checkpoint kinases, Aurora kinases, Pim-1 and/or tyrosine kinases using pyrazolo[1,5-a]pyrimidine compounds or pharmaceutical compositions including such compounds and methods of treatment, prevention, inhibition or amelioration of one or more diseases associated with such protein kinases using such compounds or pharmaceutical compositions.
  • In one aspect, the present invention provides a method of inhibiting activity of one or more kinases in a patient, wherein the kinases are selected from the group consisting of Akt kinases, Checkpoint kinases (e.g., CHK-1, CHK-2 etc), Pim kinases and Aurora kinases (e.g., Aurora-1, Aurora-2, Aurora-3 etc), the method comprising: administering a therapeutically effective amount of at least one compound, or a pharmaceutically acceptable salt, solvate, ester, isomer or prodrug of the compound, to a patient in need thereof, the compound being represented by any of the structural following formulas I through VI, as well as the various compounds in the patents and patent applications cited for the compounds of formulas I through VI, as well as the compounds disclosed in copending patent applications Serial No. ______ (Attorney Docket No. OC01617K3, OC01618K2 and OC01619K2) filed of even date herewith:

Similar preparations of solvates, hemisolvate, hydrates and the like are described by E. C. van Tonder et al, AAPS PharmSciTech., 5(1), article 12 (2004); and A. L. Bingham et al, Chem. Commun., 603-604 (2001). A typical, non-limiting, process involves dissolving the inventive compound in desired amounts of the desired solvent (organic or water or mixtures thereof) at a higher than ambient temperature, and cooling the solution at a rate sufficient to form crystals which are then isolated by standard methods. Analytical techniques such as, for example I. R. spectroscopy, show the presence of the solvent (or water) in the crystals as a solvate (or hydrate).
  • “Effective amount” or “therapeutically effective amount” is meant to describe an amount of compound or a composition of the present invention effective in inhibiting the above-noted diseases and thus producing the desired therapeutic, ameliorative, inhibitory or preventative effect.

In addition, when a compound of Formulas I-VI contains both a basic moiety, such as, but not limited to a pyridine or imidazole, and an acidic moiety, such as, but not limited to a carboxylic acid, zwitterions (“inner salts”) may be formed and are included within the term “salt(s)” as used herein. Pharmaceutically acceptable (i.e., non-toxic, physiologically acceptable) salts are preferred, although other salts are also useful. Salts of the compounds of the Formula Formulas I-VI may be formed, for example, by reacting a compound of Formulas I-VI with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilization.

  • Prodrugs and solvates of the compounds of the invention are also contemplated herein. A discussion of prodrugs is provided in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems (1987) 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, (1987) Edward B. Roche, ed., American Pharmaceutical Association and Pergamon Press. The term “prodrug” means a compound (e.g., a drug precursor) that is transformed in vivo to yield a compound shown above as being useful in the methods of this invention or a pharmaceutically acceptable salt, hydrate or solvate of the compound. The transformation may occur by various mechanisms (e.g., by metabolic or chemical processes), such as, for example, through hydrolysis in blood. A discussion of the use of prodrugs is provided by T. Higuchi and W. Stella, “Pro-drugs as Novel Delivery Systems,” Vol. 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987.

  • Similarly, if a compound shown above as being useful in the methods of this invention contains an alcohol functional group, a prodrug can be formed by the replacement of the hydrogen atom of the alcohol group with a group such as, for example, (C1-C6)alkanoyloxymethyl, 1-((C1-C6)alkanoyloxy)ethyl, 1-methyl-1-((C1-C6)alkanoyloxy)ethyl, (C1-C6)alkoxycarbonyloxymethyl, N-(C1-C6)alkoxycarbonylaminomethyl, succinoyl, (C1-C6)alkanoyl, α-amino(C1-C4)alkanyl, arylacyl and α-aminoacyl, or α-aminoacyl-α-aminoacyl, where each α-aminoacyl group is independently selected from the naturally occurring L-amino acids, P(O)(OH)2, —P(O)(O(C1-C6)alkyl)2 or glycosyl (the radical resulting from the removal of a hydroxyl group of the hemiacetal form of a carbohydrate), and the like.
  • If a compound shown above as being useful in the methods of this invention incorporates an amine functional group, a prodrug can be formed by the replacement of a hydrogen atom in the amine group with a group such as, for example, R-carbonyl, RO-carbonyl, NRR′-carbonyl where R and R′ are each independently (C1-C10)alkyl, (C3-C7) cycloalkyl, benzyl, or R-carbonyl is a natural α-aminoacyl or natural α-aminoacyl, —C(OH)C(O)OY1 wherein Y1 is H, (C1-C6)alkyl or benzyl, —C(OY2)Y3 wherein Y2 is (C1-C4) alkyl and Y3 is (C1-C6)alkyl, carboxy (C1-C6)alkyl, amino(C1-C4)alkyl or mono-N— or di-N,N-(C1-C6)alkylaminoalkyl, —C(Y4)Y5 wherein Y4 is H or methyl and Y5 is mono-N— or di-N,N-(C1-C6)alkylamino morpholino, piperidin-1-yl or pyrrolidin-1-yl, and the like.
  • One or more compounds of the invention may exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like, and it is intended that the invention embrace both solvated and unsolvated forms. “Solvate” means a physical association of a compound of this invention with one or more solvent molecules. This physical association involves varying degrees of ionic and covalent bonding, including hydrogen bonding. In certain instances the solvate will be capable of isolation, for example when one or more solvent molecules are incorporated in the crystal lattice of the crystalline solid. “Solvate” encompasses both solution-phase and isolatable solvates. Non-limiting examples of suitable solvates include ethanolates, methanolates, and the like. “Hydrate” is a solvate wherein the solvent molecule is H2O.
  • One or more compounds shown above as being useful in the methods of this invention of the invention may optionally be converted to a solvate. Preparation of solvates is generally known. Thus, for example, M. Caira et al, J. Pharmaceutical Sci., 93(3), 601-611 (2004) describe the preparation of the solvates of the antifungal fluconazole in ethyl acetate as well as from water. Similar preparations of solvates, hemisolvate, hydrates and the like are described by E. C. van Tonder et al, AAPS PharmSciTech., 5(1), article 12 (2004); and A. L. Bingham et al, Chem. Commun., 603-604 (2001). A typical, non-limiting, process involves dissolving the inventive compound in desired amounts of the desired solvent (organic or water or mixtures thereof) at a higher than ambient temperature, and cooling the solution at a rate sufficient to form crystals which are then isolated by standard methods. Analytical techniques such as, for example I. R. spectroscopy, show the presence of the solvent (or water) in the crystals as a solvate (or hydrate).

Pharmaceutically acceptable (i.e., non-toxic, physiologically acceptable) salts are preferred, although other salts are also useful. Salts of the compounds shown above as being useful in the methods of this invention may be formed, for example, by reacting a compound shown above as being useful in the methods of this invention with an amount of acid or base, such as an equivalent amount, in a medium such as one in which the salt precipitates or in an aqueous medium followed by lyophilization.

Stahl et al, Camille G. (eds.) Handbook of Pharmaceutical Salts. Properties, Selection and Use. (2002) Zurich: Wiley-VCH; S. Berge et al, Journal of Pharmaceutical Sciences (1977) 66(1) 1-19; P. Gould, International J. of Pharmaceutics (1986) 33 201-217; Anderson et al, The Practice of Medicinal Chemistry (1996), Academic Press, New York; and in The Orange Book (Food & Drug Administration, Washington, D.C. on their website). These disclosures are incorporated herein by reference thereto.
  • Exemplary basic salts include ammonium salts, alkali metal salts such as sodium, lithium, and potassium salts, alkaline earth metal salts such as calcium and magnesium salts, salts with organic bases (for example, organic amines) such as dicyclohexylamines, t-butyl amines, and salts with amino acids such as arginine, lysine and the like. Basic nitrogen-containing groups may be quarternized with agents such as lower alkyl halides (e.g. methyl, ethyl, and butyl chlorides, bromides and iodides), dialkyl sulfates (e.g. dimethyl, diethyl, and dibutyl sulfates), long chain halides (e.g. decyl, lauryl, and stearyl chlorides, bromides and iodides), aralkyl halides (e.g. benzyl and phenethyl bromides), and others.

  • Pharmaceutically acceptable esters of the present compounds include the following groups: (1) carboxylic acid esters obtained by esterification of the hydroxy groups, in which the non-carbonyl moiety of the carboxylic acid portion of the ester grouping is selected from straight or branched chain alkyl (for example, acetyl, n-propyl, t-butyl, or n-butyl), alkoxyalkyl (for example, methoxymethyl), aralkyl (for example, benzyl), aryloxyalkyl (for example, phenoxymethyl), aryl (for example, phenyl optionally substituted with, for example, halogen, C1-4alkyl, or C1-4alkoxy or amino); (2) sulfonate esters, such as alkyl- or aralkylsulfonyl (for example, methanesulfonyl); (3) amino acid esters (for example, L-valyl or L-isoleucyl); (4) phosphonate esters and (5) mono-, di- or triphosphate esters. The phosphate esters may be further esterified by, for example, a C1-20 alcohol or reactive derivative thereof, or by a 2,3-di(C6-24)acyl glycerol.
  • Compounds of formulas I through VI, as well as the compounds disclosed in copending patent applications Serial No. ______ (Attorney Docket No. OC01617K3, OC01618K2 and OC01619K2) filed of even date herewith, and salts, solvates, esters and prodrugs thereof, may exist in their tautomeric form (for example, as an amide or imino ether). All such tautomeric forms are contemplated herein as part of the present invention.
  • The compounds of formulas I through VI, as well as the compounds disclosed in copending patent applications Serial No. ______ (Attorney Docket No. OC01617K3, OC01618K2 and OC01619K2) filed of even date herewith may contain asymmetric or chiral centers, and, therefore, exist in different stereoisomeric forms. It is intended that all stereoisomeric forms of the compounds of formulas I through VI, as well as the compounds disclosed in copending patent applications Serial No. ______ (Attorney Docket No. OC01617K3, OC01618K2 and OC01619K2) filed of even date herewith, as well as mixtures thereof, including racemic mixtures, form part of the present invention. In addition, the present invention embraces all geometric and positional isomers. For example, if a compound of formulas I through VI, as well as the compounds disclosed in copending patent applications Serial No. ______ (Attorney Docket No. OC01617K3, OC01618K2 and OC01619K2) filed of even date herewith incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the invention.
  • Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as, for example, by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Also, some of the compounds of Formula (I) may be atropisomers (e.g., substituted biaryls) and are considered as part of this invention. Enantiomers can also be separated by use of chiral HPLC column.
  • It is also possible that the compounds shown above as being useful in the methods of this invention may exist in different tautomeric forms, and all such forms are embraced within the scope of the invention. Also, for example, all keto-enol and imine-enamine forms of the compounds are included in the invention.
  • All stereoisomers (for example, geometric isomers, optical isomers and the like) of the present compounds (including those of the salts, solvates, esters and prodrugs of the compounds as well as the salts, solvates and esters of the prodrugs), such as those which may exist due to asymmetric carbons on various substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons), rotameric forms, atropisomers, and diastereomeric forms, are contemplated within the scope of this invention, as are positional isomers (such as, for example, 4-pyridyl and 3-pyridyl). (For example, if a compound shown above as being useful in the methods of this invention incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the invention. Also, for example, all keto-enol and imine-enamine forms of the compounds are included in the invention.) Individual stereoisomers of the compounds of the invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers. The chiral centers of the present invention can have the S or R configuration as defined by the IUPAC 1974 Recommendations. The use of the terms “salt”, “solvate”, “ester”, “prodrug” and the like, is intended to equally apply to the salt, solvate, ester and prodrug of enantiomers, stereoisomers, rotamers, tautomers, positional isomers, racemates or prodrugs of the inventive compounds.

Tritiated (i.e., 3H) and carbon-14 (i.e., 14C) isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., 2H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Isotopically labelled compounds shown above as being useful in the methods of this invention can generally be prepared by following procedures analogous to those disclosed in the Schemes and/or in the Examples hereinbelow, by substituting an appropriate isotopically labelled reagent for a non-isotopically labelled reagent.

    • 2) His-CHK1, In House Lot P976, MW˜30 KDa, stored at −80° C.
      • 6 nM is required to yield positive controls of ˜5,000 CPM. For 1 plate (100 rxn): dilute 8 μL of 235 μg/mL (7.83 μM) stock in 2 mL Kinase Buffer. This makes a 31 nM mixture. Add 20 μL/well. This makes a final reaction concentration of 6 nM.
    • 3) CDC25C Biotinylated peptide.
      • Dilute CDC25C to 1 mg/mL (385 μM) stock and store at −20° C. For 1 plate (100 rxn): dilute 10 μL of 1 mg/mL peptide stock in 2 ml Kinase Buffer. This gives a 1.925 μM mix. Add 20 μL/rxn. This makes a final reaction concentration of 385 nM.
    • 4) ATP Mix.
      • For 1 plate (100 rxn): dilute 10 μL of 1 mM ATP (cold) stock and 2 μL fresh P33-ATP (20 uCi) in 5 ml Kinase Buffer. This gives a 2 uM ATP (cold) solution; add 50 μl/well to start the reaction. Final volume is 100 μl/rxn so the final reaction concentrations will be 1 μM ATP (cold) and 0.2 μCi/rxn.
    • 5) Stop Solution:
      • For 1 plate add: To 10 mL Wash Buffer 2 (2M NaCl 1% H3PO4): 1 mL SPA bead slurry (50 mg); Add 100 μL/well
    • 6) Wash buffer 1: 2 M NaCl

          IC50 DETERMINATIONS: Dose-response curves were plotted from inhibition data generated, each in duplicate, from 8 point serial dilutions of inhibitory compounds. Concentration of compound was plotted against % kinase activity, calculated by CPM of treated samples divided by CPM of untreated samples. To generate IC50 values, the dose-response curves were then fitted to a standard sigmoidal curve and IC50 values were derived by nonlinear regression analysis.
  • The IC50 values for a non-limiting list of illustrative compounds useful in the methods of the present invention determined according to the above method are shown earlier. Several compounds useful in the present invention exhibited not only excellent Checkpoint kinase (e.g., CHK-1) inhibitory activity but also surprisingly high ratio of Checkpoint kinase (e.g., CHK-1) inhibition versus cyclin dependent kinase (such as, for example CDK1 or CDK2) inhibition showing a high selectivity in targeting the kinase. Thus, for example, several compounds exhibited CHK-1 inhibition at least five-fold (five times) their respective CDK (e.g. CDK2) inhibition. Several compounds exhibited CHK-1 inhibition at least ten-fold their respective CDK (e.g. CDK2) inhibition. Several compounds exhibited CHK-1 inhibition at least fifty-fold their respective CDK (e.g. CDK2) inhibition. Certain pyrazolopyrimidines compounds exhibited CHK-1 inhibition at least five-fold their respective CDK (e.g. CDK2) inhibition. Certain pyrazolopyrimidines exhibited CHK-1 inhibition at least ten-fold their respective CDK (e.g. CDK2) inhibition. Certain pyrazolopyrimidine compounds exhibited CHK-1 inhibition at least fifty-fold their respective CDK (e.g. CDK2) inhibition. The CDK (e.g., CDK1 and CDK2) activities of the various compounds useful in the methods of the present invention are disclosed in the afore-mentioned published and co-pending patent applications, including, for example, Attorney Docket Nos. OC06284 and OC01617K3 that are incorporated by reference thereto. One skilled in the art would find such high selectivities desirable under certain circumstances.
  • While the present invention has been described with in conjunction with the specific embodiments set forth above, many alternatives, modifications and other variations thereof will be apparent to those of ordinary skill in the art. All such alternatives, modifications and variations are intended to fall within the spirit and scope of the present invention.
