instability, selective ATR inhibition has been recognized as a promising new approach in cancer therapy. We now report the identification and preclinical evaluation of the novel, clinical ATR inhibitor BAY 1895344. Starting from quinoline 2 with weak ATR inhibitory activity, lead optimization efforts focusing on potency, selectivity, and oral bioavailability led to the discovery of the potent, highly selective
ATR激酶通过激活DNA损伤修复的基本信号通路,特别是对复制压力的响应,在DNA损伤应答中起关键作用。由于DNA损伤和复制压力是基因组不稳定的主要来源,因此选择性ATR抑制已被认为是癌症治疗中一种有希望的新方法。现在,我们报告新颖的临床ATR抑制剂BAY 1895344的鉴定和临床前评估。从喹啉2开始由于ATR抑制活性较弱,针对效价,选择性和口服生物利用度的前导优化工作导致发现了有效的,高选择性的,口服的ATR抑制剂BAY 1895344,在携带某些DNA损伤的癌症异种移植模型中显示出强大的单一疗法功效维修缺陷。此外,BAY 1895344与某些诱导DNA损伤的化学疗法联合治疗可产生协同的抗肿瘤活性。BAY 1895344目前正在对晚期实体瘤和淋巴瘤(NCT03188965)的患者进行临床研究。
