SU9516，≥95% (HPLC)

A cell-permeable 3-substituted indolinone compound that displays anti-proliferative and proapoptotic properties in tumor cells. Acts as a potent, selective, reversible, and ATP-competitive inhibitor of cyclin dependent kinases (Cdks; IC₅₀ = 22 nM for Cdk2/A; 40 nM for Cdk1/B; 200 nM for Cdk4/D1). It shows no significant effect (IC₅₀ >10 µM) on the activities of PKC, p38, PDGFRβ, or EGFR. Inhibits the proliferation of growth factor-stimulated colon carcinoma cells by binding to Cdk2 and preventing the phosphorylation of pRb and its dissociation from E2F.
