  Reinvestigation of 1,3,4-Thiadiazol-2(3H)-iminium Bromide in the Two-Step Synthesis of Imidazo[2,1-b][1,3,4]thiadiazoles

  摘要：

  The synthesis of 1,3,4-thiadiazol-2(3H)-iminium bromides, which are intermediates in the most commonly used synthetic approach to imidazo [2,1-b] [1,3,4]thiadiazoles, and a single crystal X-ray diffraction study of one of these iminium bromides are described. Cyclization of the resulting 1,3,4-thiadiazol-2(3H)-iminium bromides under microwave irradiation afforded imidazo [2,1-b] [1,3,4]thiadiazoles in 80-100% yields.

  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.

  monkey thrombosis model. Beginning with a high-throughput screening hit, we identified an imidazothiadiazole-based PAR4 antagonist chemotype. Detailed structure-activity relationship studies enabled optimization to a potent, selective, and orally bioavailable PAR4 antagonist, UDM-001651. UDM-001651 was evaluated in a monkey thrombosis model and shown to have robust antithrombotic efficacy and no prolongation

  为了确定新型抗血栓形成剂，我们通过在猴子血栓形成模型中开发和评估工具化合物UDM-001651，研究了蛋白酶激活的受体4（PAR4）拮抗作用。从高通量筛选开始，我们确定了基于咪唑并噻二唑的PAR4拮抗剂化学型。详细的结构-活性关系研究能够优化有效，选择性和口服生物利用的PAR4拮抗剂UDM-001651。UDM-001651在猴子血栓形成模型中进行了评估，显示具有强大的抗血栓形成功效，并且不会延长肾脏的出血时间。优异的疗效和安全性相结合，强有力地验证了PAR4拮抗作用是一种有前途的抗血栓形成机制。
