Description:
CGP74514A is a CDK1 inhibitor with potential anticancer activity. In U937 cells, CGP74514A- induced apoptosis (5 microM) became apparent within 4 hr and approached 100% by 24 hr. The pan- caspase inhibitor Boc-fmk and the caspase-8 inhibitor lETD-fmk opposed CGP74514A-induced caspase-9 activation and PARP degradation, but not cytochrome c or Smac/DIABLO release. CGP74514A-mediated apoptosis was substantially blocked by ectopic expression of full-length Bel- 2, a loop-deleted mutant Bcl-2, and Bcl-x(L). CGP74514A treatment (5 microM; 18 hr) resulted in increased p21(CIP1) expression, p27(KIP1) degradation, diminished E2F1 expression, and dephosphorylation of p34(CDC2). It also induced early (i.e., within 2 hr) inhibition of CDK1 activity and dephosphorylation of pRb, followed by pRb degradation, but did not block pRb phosphorylation at CDK2- and CDK4- specific sites. These findings indicate that the selective CDK1 inhibitor, CGP74514A, induces complex changes in cell cycle-related proteins in human leukemia cells accompanied by extensive mitochondrial damage, caspase activation, and apoptosis.

1.CGP74514A enhances TRAIL-induced apoptosis in breast cancer cells by reducing X-linked inhibitor of apoptosis protein.
Park S1, Shim SM2, Nam SH1, Andera L3, Suh N4, Kim I5. Anticancer Res. 2014 Jul;34(7):3557-62.
BACKGROUND: Despite the selectivity of Tumor necrosis factor Related Apoptosis-Inducing Ligand (TRAIL) for cancer cell killing activity, breast cancer cells are resistant to TRAIL-induced apoptosis for various reasons.
