Description

血小板聚集抑制剂及其制备方法和用途
技术领域
本发明涉及血小板聚集抑制剂、其药用组合物和它们的制备方法,以及它们在制备血小板聚集抑制剂中的用途,属于医药技术领域。
背景技术
血栓栓塞性疾病,例如急性心肌梗塞和中风在发展中国家仍然是最常见的死亡和发病原因。它是由各种内在和外在因素导致动脉和静脉血管内形成血栓或栓塞,并进一步导致组织和器官功能受损的病理过程。它是心脑血管疾病之一,临床非常常见,也是多种其余心脑血管疾病的病因和并发症。血栓一旦形成往往造成不可逆的严重后果。
一个稳定的血小板栓子的形成需要经过3个不同阶段,即血小板黏附,血小板活化扩增和血小板聚集。目前已采取许多策略通过干扰血小板黏附、活化或聚集以降低病理性血栓形成的风险。血小板活化在血栓形成并发症中起关键作用。因此抗血小板治疗仍是临床上预防和治疗血栓性疾病的重要手段。
目前已上市的血小板聚集抑制作用的药物有氯吡格雷,替格瑞洛等,种类十分有限且有一定出血副作用,因此,研制高效和低出血副作用的血小板聚集抑制剂具有良好的应用前景。
