Discovery and structural optimization of pyrazole derivatives as novel inhibitors of Cdc25B

Bioorg Med Chem Lett. 2010 May 1;20(9):2876-9. doi: 10.1016/j.bmcl.2010.03.040. Epub 2010 Mar 11.

Abstract

Structural optimization and preliminary structure-activity relationship studies of a series of N-substituted maleimide fused-pyrazole analogues with Cdc25B inhibitory activity, starting from a high-throughput screening hit, are illustrated. A simplified 3,5-diacyl pyrazole analogue was obtained as the most potent compound (118, IC(50)=0.12 microM) with a 270-fold increase in potency.
