Biological Activity for Flavopiridol hydrochloride

Flavopiridol hydrochloride is a cyclin-dependent kinase (cdk) inhibitor (reported IC₅₀ values are 6 - 25 nM and 84 - 200 nM for cdk9 and cdk2, respectively, and <0.85 μM for cdk1, cdk4, cdk5 and cdk7). Induces cell cycle arrest at G1 and G2 phase. Potently inhibits the growth of breast and lung cancer cell lines (IC₅₀ = 25 - 160 nM) in vitro.
