sensing replication stress (RS), and has been considered as a potential target for cancer therapy. Herein, we report the discovery of a series of 6,7-dihydro-5H-pyrrolo[3,4-d]-pyrimidine derivatives as a new class of ATR inhibitors. Among them, compound 5g exhibits an IC50 value of 0.007 μM against ATR kinase. In vitro, 5g displays good anti-tumor activity and could significantly reduce the phosphorylation
共济失调毛细血管扩张症和 Rad3 相关 (ATR) 激酶是 DNA 损伤反应 (DDR) 中的关键调节蛋白,负责感知复制压力 (RS),并被认为是癌症治疗的潜在靶点。在此,我们报告了一系列 6,7-二氢-5 H-吡咯并[3,4- d ]-嘧啶衍生物作为一类新型 ATR 抑制剂的发现。其中,化合物5g对 ATR 激酶的 IC 50值为 0.007 μM。体外, 5g具有良好的抗肿瘤活性,可显着降低 ATR 及其下游信号蛋白的磷酸化水平。总体而言,这项研究为后续针对 ATR 激酶的药物发现提供了一种有前途的先导化合物。
