Description

Palbociclib (PD 0332991) isethionate is an orally active selective CDK4 and CDK6 inhibitor with IC50 values of 11 and 16 nM, respectively. Palbociclib isethionate has potent anti-proliferative activity and induces cell cycle arrest in cancer cells, which can be used in the research of HR-positive and HER2-negative breast cancer and hepatocellular carcinoma.

Biological activity

In Vitro Palbociclib dihydrochloride (0-1 μM, 24 h) inhibits Rb Phosphorylation at Ser795 in MDA-MB-435 cells with an IC50 value of 0.063 μM, and obtains similar effects on both Ser780 and Ser795 phosphorylation in the Colo-205 colon carcinoma. Palbociclib dihydrochloride (0-10 μM, 24 h) arrests MDA-MB-453 cells exclusively in G1 phase. Palbociclib dihydrochloride (500 nM, 7 days) increases expression of homologous genes (H2d1, H2k1, and B2m) in MDA-MB-453 and MDA-MB-361 cells. Palbociclib dihydrochloride (0-1 μM, 6 days) inhibits growth of several luminal ER-positive as well as HER2-amplified breast cancer cell lines, with IC50 values ranging from 4 nM to 1 μM. Palbociclib dihydrochloride (0-1 μM, 3 days) inhibits the proliferation of human liver cancer cell lines with IC50 values ranging from 0.01 μM to 3.49 μM, and induces a reversible cell cycle arrest. In Vivo Palbociclib isethionate (oral adminstration, 75 or 150 mg/kg, daily for 14 days) produces rapid tumor regressions and delays tumor growth. Palbociclib isethionate (oral adminstration, 90 mg/kg, daily for 12 days) reduces Treg numbers and the Treg:CD8 ratio in the spleen and lymph nodes in tumor-free mice, demonstrating the tumor-independent effects. Palbociclib isethionate (oral administration, 100 mg/kg, daily for 1 week) has potent antitumour effects in genetically engineered mosaic mouse model of liver cancer.
