CDK4 / CDK6 inhibitor

Functions

Potent and selective inhibitor of Cdk4, IC50 = 11 nM and Cdk6, IC50 = 16 nM.  Inhibits phosphorylation of Rb protein and cell cycle progression through G1 in primary 5T33MM cells and sensitized these cells to killing by a proteasome inhibitor (bortezomib) in mouse models. Induces autophagy and senescence in AGS gastric cancer cells.  Clinically useful breast cancer agent. Cell cycle inhibitors boost tumor immunogenicity.

Application Procedures

First dissolved in DMSO (up to 2 mg/ml with warming), then diluted to aqueous buffer. Solutions in DMSO may be stored at -20°C for up to 1 month.
