SU9516

SU-9516 is a 3-substituted indolinone CDK inhibitor with IC50 of 22 nM, 40 nM, and 200 nM for CDK2, CDK1, and CDK4, respectively.

SU9516 shows slight activities against PKC, p38, PDGFr and EGFR, with IC50 of >10, >10, 18, and >100 μM. SU9516 (5 μM) decreases cdk2-specific Phosphorylation of pRB and inhibits cell cycle progression in RKO cells. SU9516 (5 μM) also induces apoptosis in RKO and SW480 Cells. SU9516 (5 μM) results in enhanced pRb/E2F complex formation in HT-29 cells. SU9516 enhances presence of E2F species in multiprotein complexes. SU9516 (5 μM) rapidly induces cytochrome crelease, Bax mitochondrial translocation, and apoptosis in association with pronounced down-regulation of the antiapoptotic protein Mcl-1. SU9516 causes down-regulation of Mcl-1 mRNA levels in human leukemia cells. Furthermore, SU9516 treatment results in a marked increase in reactive oxygen species production.
