A cell-permeable, potent, and ATP-competitive inhibitor of Chk2 (checkpoint kinase 2; IC= 15 nM; Ki = 37 nM). Displays ~1,000-fold greater selectivity for Chk2 compared to Cdk1/cyclin B and CK1 (IC= 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 -irradiation-induced apoptosis with an ECof 3 M and 7.6 M, respectively.
