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]quinazoline 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 μM, 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.

Due to the increasing evidence linking the PI3Kγ pathway to various disease states, PI3Kγ is becoming an important target for cancer treatment. Herein we designed and synthesized a novel series of N,4-diphenylpyrimidin-2-amine derivatives with low CDOCKER-INTERACTION-ENERGY and then evaluated their PI3Kγ in vitro inhibitory activities and in vitro antiproliferation assays against four human cancer cells. Among the compounds we synthesized, compound C8 (IC50 = 65 nM) demonstrated the most potent inhibitory activity against PI3Kγ kinase as well as at the cellular level, compared to the control drug TG100713 (IC50 = 127 nM). Moreover, molecular docking analysis was also performed to determine possible binding modes between PI3Kγ and the target compounds.

Palladium-catalyzed C-H functionalization using guanidine as the directing group was achieved under mild reaction conditions. Various guanidine derivatives were produced in moderate to good yields by using simple unactivated arenes or ethyl acrylate as the source of arylation or olefination, respectively.
