Background

SU 9516 is a selective and novel inhibitor of CDK2 with IC50 value of 22 nM. Also, it inhibits CDK1, CDK4, PKC, p38, PDGFR with IC50 value of 0.04, 0.2, >10.0, >10.0, 18.0 μM, respectively [1].

Cyclin-dependent kinase 2 (CDK2) is a member of the cyclin-dependent kinase family and is a catalytic subunit of the cyclin-dependent kinase complex Cyclin E/CDK2 or Cyclin A/CDK2, which play an important role in the G1-S phase of the cell cycle [1].

In RKO cells, SU 9516 (5 μM) decreased cdk2-specific phosphorylation of pRb by 52%. While, in SW480 cells, SU9516 (5 μM) inhibited both cdk2-specific and cdk4-specific phosphorylation of pRb by 64% and 49%, respectively. Also, SU 9516 (5 μM) resulted in G0-G1 or G2-M block and induced apoptosis in a dose-dependent way [1]. In HT-29, SW480 and RKO human colon cancer cells, SU9516 (5 μM) inhibited dissociation of pRb from E2F1 in a time-dependant way. Also, SU 9516 decreased Cyclin D1 and CDK2 by 10-60% [2]. In human leukemia cells, SU 9516 (5 μM) induced Bax mitochondrial translocation, cytochrome c release and apoptosis, which were associated with down-regulation of the antiapoptotic protein Mcl-1. Also, SU 9516 induced activation of caspase-3 and -8 [3].
