Purvalanol B may act to be a Cdk (cyclin-dependent kinase) inhibitor. IC50 values are 6, 6, 9, > 10,000, and 6 nM for cdc2/cyclin B, cdk2/cyclin A, cdk2/cyclin E, cdk4/cyclin D1 and cdk5-p35 respectively. This compound has also been shown to have antiproliferative properties, mediated by p42/p44 MAPK. Purvalanol B is an inhibitor of Cdk6 and Cdk9. It possess anti-inflammatory, anti-tumor, anti-viral, and anti-microbial properties.
