CAS#: 1233339-22-4

Description: AZ20 is an ATR protein kinase inhibitor, which inhibits ATR immunoprecipitated from HeLa nuclear extracts with an IC50 of 5 nM and ATR mediated phosphorylation of Chk1 in HT29 colorectal adenocarcinoma tumor cells with an IC50 of 50 nM. AZ20 potently inhibits the growth of LoVo colorectal adenocarcinoma tumor cells in vitro and has high free exposure in mouse following moderate oral doses. AZ20 is a useful compound to explore ATR pharmacology in vivo.
