BMS-265246 is a potent and selective pyra-zolopyridine based inhibitor of cdk2/cyclinE, cdk1/cyclinB and cdk4/ cyclinD.

bms265246 is a potent and selective inhibitor for cdk1 and cdk2 (ic50= 6 nm and 9 nm)cyclin-dependent kinases (cdk) are a group of serine/threonine kinases. they are activated by coupling to cyclin and participate in the regulation of cell cycle.bms265246 inhibited the cdk4/cycd activity and prevented a2780 cytox (ic50 = 0.23 μm and 0.76 μm) [1]. in hct-116 cells, bms-265246 blocked the cell proliferation (ec50= 0.293 μm—0.492 μm). following the treatment of bms-265246, low dna intensity, large round nuclei and 4n dna content were observed in the dominant cell population –g2 arrested cells.
