Description

General description

A cell-permeable thiourea compound that selectively inhibits the kinase activity of ATM and ATR (IC₅₀ = ~200 nM) without significant effect against other PIKK family members (PI 3-K, mTOR, and DNA-PK) or kinases that are known to phosphorylate p53 (ERK, CK1, Cdk2, JNK, PKC, CAK, Chk1, PKR, and p38). Shown to reverse senescence in human primary BJ and HMEC cells. Unlike LY 294002 (Cat. No. 440202 and 440204), this inhibitor does not interfere with cellular PI 3-K/PDK1/Akt signaling pathway.
