Abstract:
:We disclose a novel series of indenopyrazole-based cyclin-dependent kinase (CDK) inhibitors. Kinetic experiments confirmed our initial molecular modeling studies that the compounds are competitive with respect to adenosine 5'-triphosphate (ATP) and bind in the kinase ATP pocket. A unique combination of active pharmacophores led us to a series of semicarbazide-based inhibitors that are highly potent against CDK2 and CDK4 while maintaining selectivity against other relevant serine/threonine kinases. These compounds were active against a transformed human colon cancer cell line (HCT116) while maintaining an acceptable margin of activity against a normal fibroblast cell line. The compounds were found to be highly protein bound in our cell-based assay with the exception of 11k, which maintained a reasonable level of activity in the presence of human plasma proteins.
