| Hazard Information | Back Directory | [Uses]
Cell permeable, potent, selective and ATP-competitive inhibitor of CDK2/cyclin A (IC50=22nM), CDK1/cyclin B (IC50=40nM) and CDK4/cyclin D1 (IC50=200nM). Has no effect on the activity of PKC, p38, PDGFRβ and EGFR (IC50>10μM). Displays anti-proliferative and pro-apoptotic properties in tumor cells. Inhibits proliferation of growth factor-stimulated colon carcinoma cells by binding to CDK2 and thus preventing the phosphorylation of pRb and its dissociation from E2F. | [Definition]
ChEBI: 3-(1H-imidazol-5-ylmethylidene)-5-methoxy-1H-indol-2-one is a member of indoles. | [Biological Activity]
Potent, selective cdk2 inhibitor (IC 50 values are 0.022, 0.04, >10, >10, 18 and >100 μ M for cdk2, cdk1, cdk4, PKC, p38, PDGFR and EGFR respectively). Inhibits pRb phosphorylation causing enhanced pRB/E2F complex formation and induces G 1 and G 2 -M cell cycle arrest. Transcriptionally downregulates Mcl-1 and has antiproliferative, cytostatic and pro-apoptotic effects in vitro . | [storage]
