SU 9516

The Uses of SU 9516

SU 9516 is a 3-substituted indolinone CDK inhibitor with potent and selective inhibition towards cyclin-dependant kinases.

What are the applications of Application

SU 9516 is a cell permeable, potent, selective and ATP-competitive inhibitor

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 .
