一种有效的选择性 CDK4/6 抑制剂，IC50 为 11 nM/16 nM；对 CDK2A 无抑制作用 (IC50>5 uM)；抑制 MDA-MB453 细胞，IC50 为 0.16 uM。

A potent and selective inhibitor of CDK4/6 with IC50 of 11 nM/16 nM; no inhibition for CDK2A (IC50>5 uM); inhibits MDA-MB453 cells with IC50 of 0.16 uM; shows antiproliferative effect against retinoblastoma (Rb)-positive tumor cells in vitro and reduces the phospho-Ser780/Ser795 on the Rb protein; orally bioavailable.Breast Cancer Approved.

Cell Cycle Analysis Cell Line:MDA-MB-453 cells Concentration:0-1 μM Incubation Time:24 h Result:Arrested MDA-MB-453 cells in G1.Cell Proliferation Assay Cell Line:ER-positive as well as HER2-amplified breast cancer cell lines (MDA-MB-175, ZR-75-30, CAMA-1, etc.)Concentration:0-10 μM Incubation Time:6 days Result:Inhibited growth of luminal ER-positive as well as HER2-amplified breast cancer cell lines.

Animal Model:Mice bearing Colo-205 colon carcinoma xenografts (p16 deleted) Dosage:75, 150 mg/kg, daily for 14 days Administration:Oral adminstration Result:Produced rapid tumor regressions and a corresponding tumor growth delay of ~50 days.Animal Model:Tumor-free female FVB mice Dosage:90 mg/kg (diluted in 50 nM sodium D-lactate), daily for 12 days Administration:Oral adminstration Result:Reduced total thymic mass and immature CD4+ and CD8+ double-positive thymocytes, and increased the fractions of CD4+ and CD8+ single-positive thymocytes.Animal Model:Genetically engineered mosaic mouse model of liver cancer (Myc;p53-sgRNA)Dosage:100 mg/kg, daily for 1 week.Administration:Oral adminstrationResult:Decreased the luminescence signal in liver and delayed tumour growth.
