Description
技术领域
本发明属于医药技术领域,具体涉及一种苯骈三氮唑烷基衍生物在制备治疗或预防心血管疾病的药物中的应用。
背景技术
心血管疾病是危害人类健康的第一杀手。心血管疾病中,仅仅是缺血性心脏病的死亡人数就超过全部肿瘤的死亡人数。急性冠脉综合征、缺血性脑卒中的共同病理学基础是血小板异常激活引起的动脉血栓形成,抗血小板治疗效果肯定。动脉粥样斑块破裂是血小板异常激活的常见诱因,发病3-6小时支架置入具有立竿见影的效果。支架作为血管内异物,本身有激活血小板、诱发血栓形成的风险。置入支架后,为防止支架内血栓形成,需长期甚至终身服用抗血小板药,抗血小板药临床需求巨大。
临床上现有抗血小板药物主要有环加氧酶抑制剂(如阿司匹林)、P2Y12受体拮抗剂(如氯吡格雷、普拉格雷)、磷酸二酯酶抑制剂(如西洛他唑)、纤维蛋白原受体拮抗剂、凝血酶受体PAR1拮抗剂等五大类。但上述五类抗血小板药临床也存在不足:口服抗血小板药物阿司匹林、氯吡格雷起效缓慢;多数口服抗血小板药物如阿司匹林、氯吡格雷抗血小板作用温和、抗血小板治疗不能完全防止临床血栓事件的发生。此外,患者存在“阿司匹林抵抗”、“氯吡格雷抵抗”,反应明显者容易出现出血副作用,因此研究新的抗血小板药具有临床意义。
发明内容

实施例8
化合物(1)~(7)对血小板聚集的抑制活性研究
(1)主要实验仪器与试剂
酶联免疫分析仪(SYNERGY H1,BioTek Instruments,Inc.);孵育箱(VORTEMP56,美国莱伯特公司);酶标板振荡器(benchmate S4P-D,Oxford Lab);十万分之一天平(M205DU,梅特勒托利多);超纯水机(Medium-S800GUVF,HITECH);高速离心机(5430R,Centrifuge)。
化合物1~7;盐酸沙格雷酯(>98%,上海源叶生物科技有限公司);ADP(AR,hyphen biomed);二甲基亚砜(AR,国药集团化学试剂有限公司)。
(2)实验方法
2.1富血小板血浆(PPP)和贫血小板血浆(PRP)的制备
家兔心脏采血,置于含标记的EDTA-K2抗凝管中,上下轻柔颠倒使抗凝剂于血液充分混合后,于采血后0.5h之内离心分离血浆。将其离心(4℃,200g,10min)后取上清液,即得富血小板血浆(PPP);将剩余部分继续离心(4℃,1500g,15min)后取上清液,即得贫血小板血浆(PRP)。
2.2血小板聚集率的测定
在孔板中加入90μLPRP,以及5μL目标化合物/阳性对照品(终浓度为10μmol/L、1μmol/L、 0.1μmol/L),振摇15min,于37℃孵育箱中温育5min。加入5μL诱导剂ADP,振摇5min,测得OD值(Aspl)。
2.3数据处理
PRP由于血小板处于均匀分散状态而具有一定的浊度,其浊度的高低与血小板数成正相关。浊度在酶标仪上则表现为吸光度。当PRP加入诱导剂后,部分血小板聚集,使得PRP的浊度下降,表现为吸光度值下降。PRP中血小板聚集程度越高,吸光度下降越大。因此,通过测定一段时间后吸光度的变化可在一定程度反应血小板的聚集性能。
式中Aspl为加入ADP或胶原振摇5min后吸光度;Aprp、Appp为PRP与PPP组吸光度;ARctrl为空白对照组血小板聚集率;ARexp为给药组血小板聚集率。
(3)结果
