The Identification of Potent, Selective, and Orally Available Inhibitors of Ataxia Telangiectasia Mutated (ATM) Kinase: The Discovery of AZD0156 (8-{6-[3-(Dimethylamino)propoxy]pyridin-3-yl}-3-methyl-1-(tetrahydro-2<i>H</i>-pyran-4-yl)-1,3-dihydro-2<i>H</i>-imidazo[4,5-<i>c</i>]quinolin-2-one)

clinical dose (<50 mg) and focused on strategies to increase both ATM potency and predicted human pharmacokinetic half-life (predominantly through the increase of volume of distribution). These efforts resulted in the discovery of 64 (AZD0156), an exceptionally potent and selective inhibitor of ATM based on an imidazo[4,5-c]quinolin-2-one core. 64 has good preclinical phamacokinetics, a low predicted clinical
当在小鼠异种移植模型中与DNA双链断裂诱导剂结合使用时,ATM抑制剂(例如7)已证明ATM抑制具有抗肿瘤潜力。然而,7的性质导致相对较高的预测临床有效剂量。为了最大程度地减少临床开发过程中的磨损,我们试图确定预测的临床剂量低(<50 mg)的ATM抑制剂,并着重于提高ATM效能和预测的人类药代动力学半衰期(主要是通过增加体积)的策略的分布)。这些努力导致发现了64(AZD0156),这是一种基于咪唑并[4,5 - c ]喹啉-2-酮核的ATM特异强效选择性抑制剂。64具有良好的临床前药代动力学,较低的预计临床剂量和较高的最大可吸收剂量。已显示64可以增强批准的药物伊立替康和olaparib在与疾病相关的小鼠模型中的功效,目前正在使用这些药物进行临床评估。
