Potent and selective ATM kinase inhibitor (IC50 = 0.6 nM in an enzyme inhibition assay). Exhibits > 600-fold selectivity for ATM over other kinases. Inhibits ATM kinase in an in vitro cellular assay (IC50 = 0.33 μM). Potentiates the antitumor effects of the topoisomerase 1 inhibitor irinotecan in tumor bearing, immunocompromised mice. Orally bioavailable. Degorce et al (2016) Discovery of novel 3-quinoline carboxamides as potent, selective and orally bioavailable inhibitors of ataxia telangiectasia mutated (ATM) kinase.
