BICYCLIC COMPOUNDS AS CDK INHIBITORSFIELD OF THE INVENTION
[0001] Disclosed herein are bicyclic compound derivatives used as inhibitors of cyclin-dependent kinases. Disclosed herein is the use of these inhibitors for inhibiting cyclin-dependent kinases, and the use of such compounds for treating cancer.BACKGROUND OF THE INVENTION
[0002] Cyclin-dependent kinases (CDKs) , a family of Ser / Thr protein kinases, function as a driver of the cell cycle (Norbury, C. and Nurse, P., Annu Rev Biochem, 61, 441-470) . During the cell cycle, CDK4 and CDK6 initiate the retinoblastoma (Rb) phosphorylation by binding to cyclinD and partially release the transcription factor E2F. Then the CDK2 forms a complex with cyclinE to fully phosphorylate Rb, entirely release E2F and initiate S-phase (Harbour, J.W. et al., Cell, 98 (6) , 859-869) . Then in the S phase, CDK2 forms a complex with cyclinA (Echalier, A. et al., Biochim Biophys Acta, 1804 (3) , 511-519) . Interestingly, in the normal cells, CDK2 is mostly not essential for the cell cycle, while in some cancer cells, CDK2 kinase activity plays a critical role in the abnormal growth process (Caruso, J.A. et al., Cancer Res, 78 (19) , 5481-5491) .
[0003] CCNE gene amplification or cyclinE overexpressed forms of cancer cells over activates CDK2, dysregulating Rb phosphorylation and resulting in cancer cell proliferation (Wood, D.J. et al., Cell Chem Biol, 26 (1) , 121-130) . Aberrant CCNE has been proved as a disease driver in multiple cancer types such as ovarian, esophageal, bladder, pancreatic and so on, which are associated with poor disease outcomes (Au-Yeung, G. et al., Clin Cancer Res, 23 (7) , 1862-1874; DeLair, D.F. et al., J Pathol, 243 (2) , 230-241; Fu, Y.P. et al., Cancer Res, 74 (20) , 5808-5818; Huber, A.R. et al., BMC Gastroenterol, 15, 80; Miller, C.T. et al., Clin Cancer Res, 9 (13) , 4819-4825) . Besides, one of the mechanisms for the clinical drug resistance of CDK4 / 6i (such as Palbociclib, Ribociclib and Abemaciclib) in ER+ HER2-breast cancer patients is the overexpression of CCNE and the activation of CDK2 (Knudsen, E.S. et al., Cell Rep, 38 (9) , 110448) . CDK2 siRNA knockdown in the Palbociclib resistant breast cancer cell lines and mouse model shows CDK2 inhibition can overcome the CDK4 / 6-inhibitor resistance (Pandey, K. et al., Cancers (Basel) , 12 (12) ) . Another potential use of CDK2 inhibitors is based on the mechanism of trastuzumab resistance. There is around 35%trastuzumab resistance incidence of cyclinE amplification or overexpression in HER2+ BC patients, which are associated with a worse clinical benefit while the trastuzumab-resistant cells are sensitive to CDK2 inhibition (Scaltriti, M. et al., Proc Natl Acad Sci U S A, 108 (9) , 3761-3766) . The CCNE1 amplification across broad cancer types predicts response to CDK2 inhibition, indicating CDK2 is a potentially impactful therapeutic target.
[0004] The low toxicity of targeting CDK2 has also been proved in the animal model. CDK2 knockout mice are viable and developed normally except for the abnormal germline cell (Berthet, C. et al., Curr Biol, 13 (20) , 1775-1785) . While single knockout of CDK1 or double knockout of CDK4 and CDK6 mice are embryonic lethal (Satyanarayana, A. and Kaldis, P., Oncogene, 28 (33) , 2925-2939) .
[0005] The crystal structure of CDK2 especially its kinase domain is highly similar to the CDK1 and the commercial CDK2 inhibitors are mostly with poor CDK1 selectivity (Wells, C.I. et al., Nat Commun, 11 (1) , 2743) . It is desirable to achieve a cancerous specific drug so as to derive a high selective CDK2 inhibitor, sparing CDK family members to limit off-target CDK-driven toxicities, especially CDK1 / CDK4 / CDK6.SUMMARY OF THE INVENTION

[0136] It may be advantageous to separate reaction products from one another and / or from starting materials. The desired product of each step or series of steps is separated and / or purified (hereinafter separated) to the desired degree of homogeneity by the techniques common in the art. Typically such separations involve multiphase extraction, crystallization from a solvent or solvent mixture, distillation, sublimation, or chromatography. Chromatography can involve any number of methods including, for example: reverse-phase and normal phase; size exclusion; ion exchange; high, medium and low pressure liquid chromatography methods and apparatus; small scale analytical; simulated moving bed ( "SMB" ) and preparative thin or thick layer chromatography, as well as techniques of small scale thin layer and flash chromatography.

[0137] “Diastereomers” refers to stereoisomers of a compound with two or more chiral centers but which are not mirror images of one another. 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 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 diastereoisomers to the corresponding pure enantiomers. Enantiomers can also be separated by use of a chiral HPLC column.
[0138] Some of the compounds disclosed herein may exist with different points of attachment of hydrogen, referred to as tautomers.

[0140] In addition, if a compound disclosed herein is obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt. Conversely, if the product is a free base, an addition salt, such as a pharmaceutically acceptable addition salt, may be produced by dissolving the free base in a suitable organic solvent and / or water and treating the solution with an acid, in accordance with conventional procedures for preparing acid addition salts from base compounds. Those skilled in the art will recognize various synthetic methodologies that may be used without undue experimentation to prepare non-toxic pharmaceutically acceptable addition salts.
[0141] As defined herein, "a pharmaceutically acceptable salt thereof" includes salts of at least one compound of Formula (I) , and salts of the stereoisomers of the compound of Formula (I) , such as salts of enantiomers, and / or salts of diastereomers.

Treatment of a cell encompasses contact of a reagent to the cell, as well as the contact of a reagent to a fluid, where the fluid is in contact with the cell. The term “administration” and “treatment” also means in vitro and ex vivo treatments, e.g., of a cell, by a reagent, diagnostic, binding compound, or by another cell. The term “subject” herein includes any organism, preferably an animal, more preferably a mammal (e.g., rat, mouse, dog, cat, and rabbit) and most preferably a human.
[0143] The term "effective amount" or “therapeutically effective amount” refers to an amount of the active ingredient, such as a compound that, when administered to a subject for treating a disease, or at least one of the clinical symptoms of a disease or disorder, is sufficient to affect such treatment for the disease, disorder, or symptom. The “therapeutically effective amount” can vary with the compound, the disease, disorder, and / or symptoms of the disease or disorder, severity of the disease, disorder, and / or symptoms of the disease or disorder, the age of the subject to be treated, and / or the weight of the subject to be treated. An appropriate amount in any given instance can be apparent to those skilled in the art or can be determined by routine experiments. In some embodiments, “therapeutically effective amount” is an amount of at least one compound and / or at least one stereoisomer thereof, and / or at least one pharmaceutically acceptable salt thereof disclosed herein effective to “treat” as defined above, a disease or disorder in a subject. In the case of combination therapy, the “therapeutically effective amount” refers to the total amount of the combination objects for the effective treatment of a disease, a disorder or a condition.
