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.

Ectopic cell cycle reactivation in neurons is associated with neuronal death in Alzheimer's disease. In cultured rodent neurons, synthetic β-amyloid (Aβ) reproduces the neuronal cell cycle re-entry observed in the Alzheimer's brain, and blockade of the cycle prevents Aβ-induced neurodegeneration.
