AZ20

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.

How to use

In Vitro:

AZ20 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.

In Vivo:

AZ20 (25, 50 mg/kg, p.o.) has high permeability combined with good stability to rat hepatocytes and, despite the lack of progress in achieving markedly higher solubility, has respectable bioavailability in a low dose rat PK study. AZ20 (25, 50 mg/kg, p.o.) leads to significant tumor growth inhibition in female nude mice bearing LoVo tumors.
