莪术二酮通过调节AMPK参与vinculin/talin介导的整合素信号通路抑制凝血酶诱导的血小板聚集
发布时间:2021-08-08 06:17
当今社会,血栓性疾病的患病人数日益上涨,逐年增高,越发威胁到了人类的生命健康。血栓的定义是血液中的有形成分在器官内膜或者血管壁附着的凝块或者堆积物,引起血管狭窄或阻塞,导致各种器官和脏器缺血和梗死,其临床表现有心脑血管疾病、冠状动脉粥样硬化、肺血栓栓塞等。目前,临床上治疗血栓的药物有很多,通过调控不同的分子途径发挥抗血栓的作用,主要分为抗血小板聚集的药物、干扰凝血的药物和经纤溶酶溶栓的药物等,分别在凝血过程的不同阶段以及血栓形成的不同阶段起着抑制作用,其中医治血栓疾病最普遍是使用抗血小板的药物。但是随着抗血小板药物的广泛运用,其引发的不良反应以及出血事件等,已受到越来越多的关注。因此,探讨血小板活化的病理机制、寻找防治血小板活化的新靶点和开发安全有效的药物是目前亟待解决的问题,对于解决抗血小板药物所引起的安全性问题和预防和治疗血栓性疾病具有十分重要的意义。现代医学研究发现,从温郁金的莪术油中分离出的莪术二酮,是莪术油的一种主要活性成分和常用的中药质量控制指标。长期以来研究发现,用凝血酶作为诱导剂,莪术二酮能够抑制血小板活化和聚集,在研究其作用靶点和具体作用机制时发现莪术二酮抗血小板聚集...

(A) Washed platelets were pretreated with normalsaline or 100 μM curdione for 10 min and incubated with 0.02 U/mLthrombin for anadditional 5 min.As a positive control, platelets were treated with 2 μg/mL tirofiban for10 min and incubated with 0.02 U/mL thrombin for an additional 5 min. (B) Thewashed platelets were incubated with 0.02 U/mL thrombin after pretreatment with 10μM cilengitide for 7 min or 100 μM curdione for 10 min. Expression was assessed byimmunoblotting. (C) Washed platelets were pretreated with 100 μM curdione for 10 minor 2 μg/mLtirofiban for 10 min and incubated with 0.02 U/mLthrombin for anadditional 5 min. Expression was assessed by immunoblotting. (D) AMPK and integrin
