Description

General description

A cell-permeable pyrazolo-pyrimidinone compound that acts as a potent, selective, and ATP-competitive inhibitor of Cdks (IC₅₀ = 48 nM, 15 nM, 9 nM, 10 nM, 71 nM, and 9 nM for Cdk1/B, Cdk2/E, Cdk3/E, Cdk5/p35, Cdk7/H/MAT1, and Cdk9, respectively). It inhibits Cdk4/D1, Cdk6/D3, and GSK-3β only at much higher concentrations (IC₅₀ = 839 nM, 282 nM, and 754 nM, respectively) and exhibits little activity towards a panel of 60 other kinases. A broad-spectrum growth inhibitor toward tumor cells, but not non-transformed quiescent fibroblasts.
