  date, only two PAR4 antagonists, BMS-986120 and BMS-986141 have entered clinical trials for thrombosis. Thus, the development of a potent and selective PAR4 antagonist with a novel chemotype is highly desirable. In this study, we explored the activity of quinazolin-4(3H)-one-based PAR4 antagonists, beginning with their IDT analogues. By repeated structural optimisation, we developed a series of highly

  蛋白酶激活受体 4 (PAR4) 是抗血小板治疗的重要靶点，可降低中风心脏病发作和血栓并发症的风险。PAR4 拮抗剂通过作用于血小板聚集的晚期扩散阶段，可以防止有害和稳定的血栓生长，同时保留初始血栓形成，并可能为其他抗血小板药物提供更安全的替代品。迄今为止，只有两种 PAR4 拮抗剂BMS-986120和BMS-986141已进入血栓形成的临床试验。因此，非常需要开发具有新化学型的强效和选择性PAR4拮抗剂。在本研究中，我们探讨了 quinazolin-4(3 H)-基于 PAR4 的拮抗剂，从其 IDT 类似物开始。通过反复的结构优化，我们开发了一系列对人血小板具有纳摩尔效力的高选择性 PAR4 拮抗剂。其中，13和30g具有 8-苯并[ d ]噻唑-2-基-取代的 quinazolin-4(3 H )-one 结构，显示出最佳活性（h.
