Description
BML-277 is a selective checkpoint kinase 2 (Chk2) inhibitor with anIC50of 15 nM.
IC50& Target
IC50: 15 nM (Chk2)[1]
In Vitro
BML-277 is an ATP-competitive inhibitor of Chk2 that dose dependently protects human CD4+and CD8+T-cells from apoptosis due to ionizing radiation. BML-277 efficiently rescues both T-cell populations from radiation-induced apoptosis in a dose-dependent manner with an observed EC50of 3?7.6 μM. The concentration of BML-277 required for radioprotection is consistent with the biochemical measurement of chk2 inhibition. Providing theKmof ATP for Chk2 is determined to be 99 μM and the Kifor BML-277 is 37 nM, and assuming that the intracellular ATP concentration is 10 mM, a 5 μM concentration of BML-277 would be expected to produce 42% inhibition of intracellular chk2[1].
