General description
A cell-permeable and reversible benzimidazolo compound that acts as a potent and ATP-competitive inhibitor of Chk2 with an IC50 of 15 nM and a Ki of 37 nM. Displays ~ 1,000-fold greater selectivity over Cdk1/B and CK1 (IC50 = 12 M and 17 M, respectively) and only weakly affects the activities of a panel of 31 kinases (<25% inhibition at 10 M), including Chk1. Shown to rescue both peripheral CD4+ and CD8+ T-cells from γ-irradiation-induced apoptosis with an EC50 of 3 M and 7.6 M, respectively. Also available as a 25 mM solution in DMSO (Cat. No. 220491).
