Rad3-related (ATR) kinase is being pursued as a new therapeutic strategy for the treatment of advanced solid tumor with specific DNA damage response deficiency. Herein, we report a series of pyrido[3,2-d]pyrimidine derivatives with potent ATR inhibitory activity through structure-based drug design. Among them, the representative compound 10q exhibited excellent potency against ATR in both biochemical and
靶向共济失调毛细血管扩张突变和 Rad3 相关 (ATR) 激酶正在被寻求作为治疗具有特定 DNA 损伤反应缺陷的晚期实体瘤的新治疗策略。在此,我们通过基于结构的药物设计报道了一系列具有有效 ATR 抑制活性的
吡啶并[3,2- d ]
嘧啶衍
生物。其中,代表性化合物10q在生化和细胞测定中均表现出优异的抗ATR功效。更重要的是, 10q在不同物种中表现出良好的肝微粒体稳定性,并且与ATM
抑制剂AZD1390联合治疗时对HT-29细胞表现出中等的抑制活性。因此,这项工作为进一步研究提供了一种有前景的抗 ATR 先导化合物。
