Potent and selective inhibitor of CDKs. More potent than olomoucine. Inhibits CDK1/cyclin B kinase (IC50 = 450 nM), CDK2 (IC50 = 700 nM) and CDK5/p35 (IC50 = 160 nM). Inhibits M phase promoting factor (MPF) kinase activity. Arrests human fibroblasts in G1 phase. Antitumor compound. Activates the mitogen-activated protein kinase pathway. Targets both the p53 and NF-kappaB pathways[10]. Has effects on calcium channel gating. Prevents DNA damage-induced cyclin A1 upregulation. Apoptosis inducer. As CYC202 in phase I clinical trials.
