摘要

5-Pyrimidinyl-2-aminothiazole 1 was identified as an inhibitor of cyclin-dependent kinases (CDKs) by a screening of the Merck sample repository. The introduction of a methyl group at the C-5 or C-6 position on the pyrimidine ring, directed toward the gate keeper residue of CDK4 (Phe93), led to significant enhancement of selectivity for CDK4 over other CDKs. Compound 3 exhibited more than 300-fold selectivity for CDK4 over CDK1, 2, 5, 7, and 9. ...
