Leírás

Általános leírás

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 K_i 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).

A cell-permeable, potent, reversible and ATP-competitive inhibitor of Chk2 (checkpoint kinase 2; IC₅₀ = 15 nM; K_i = 37 nM). Displays ~1,000-fold greater selectivity for Chk2 compared to Cdk1/cyclin B and CK1 (IC₅₀ = 12 µM and 17 µM, respectively) and only weakly affects the activities of a panel of 31 kinases (<25% inhibition at 10 µM), including Chk1. Shown to rescue both peripheral CD4⁺ and CD8⁺ T-cells from γ-irradiation-induced apoptosis with an EC₅₀ of 3 µM and 7.6 µM, respectively.
