Synthesis and SAR of 4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline derivatives as potent and selective CDK4/6 inhibitors
摘要:
CDK4/6 pathway is an attractive target for development of anti-cancer drugs. Herein, we reported the design and synthesis of a series of 4,5-dihydro-1H-pyrazolo [4,3-h]guinazoline derivatives as selective CDK4/6 inhibitors. Applied with the optimizing strategy to the initial scaffold, it is found that compound 13n is able to selectively inhibit CDK4 and CDK6 with IC50 values 0.01 and 0.026 mu M, respectively. The compound showed good anti-proliferative activity when tested in a panel of tumor cell lines with CDK4/6 related mechanism of action, the results clearly suggest that compound 13n works much better than Ly2385219 which is a selective CDK4/6 inhibitor. This compound was also found to have favorable pharmacokinetic parameters. Taken together, compound 13n could be selected for further preclinical evaluation. (C) 2018 Elsevier Masson SAS.
