Description
技术领域
本发明涉及一种具有磷酸肌酸和银杏内酯B复合结构类化合物,其制备及其在医药上的应用。
本发明还涉及所述化合物及其可药用的盐或含有其的药物组合物在具有抗血小板活化因子(PAF)诱导的血小板聚集作用,可用于缺血性中风,炎症,哮喘等与PAF因子相关的疾病预防和临床治疗中的应用。
背景技术
银杏作为药用植物由来己久,随着药物提取工艺标准化和药理作用活性研究的深入,世界各国,特别是德国、法国等欧洲国家已将银杏提取物(GBE) 广泛用于治疗呼吸系统、心脑血管系统等疾病。银杏提取物的主要有效成本是银杏内酯,是血小板活化因子(platelet-activating factor,PAF)的强拮抗物。血小板活化因子是一个很强的生理调节器,在很多生理现象上扮演着重要角色,如过敏、发炎及哮喘等等,因此寻找适当的PAF对抗物来作为医疗上的使用便是医学界一个很重要的课题。银杏内酯B(GinkgoIide B,GB)是从银杏叶中提取的一种六环笼状结构的二萜化合物,是迄今发现的最强的血小板活化因子(PAF) 拮杭剂,它直接参与血拴形成,可刺激冠状动眯和脑动脉,引起它们的收缩、痉挛,导致心肌和脑组织缺血。但是银杏内酯B是一种六环笼状结构的二萜化合物,刚性结构,不溶于水,生物利用度差,致使药效的充分发挥受到限制,影响临床应用效果。文献(Hwa,Kunetal,WO9306107)出于分离纯化的目的对银杏内酯B的结构进行了改造,但仅仅局限于分子内部手性的改交,对于其水溶性并无改善。文献(秦引林,CN101302221A;CN101967153A)报道了通过在10-位羟基成谜引入碱性氨基基团,最后通过碱性氨基成盐来提高水溶性,具体结构如以下结构II所示;文献(杨振强等,CN101880286A)则通过10-羟基与氨基酸成酯,最后利用氨基酸成盐来提高溶解性,具体结构如以下结构III所示。
磷酸肌酸在肌肉收缩的能量代谢中发挥重要作用,它是心肌和骨骼肌的化学能量储备,并用于ATP的再合成,ATP的水水解为肌动球蛋白收缩过程提供能量。作为心肌保护和能量补充剂的磷酸肌酸钠是FDP(二磷酸果糖)换代产品,能效力约为二磷酸果糖的3.16倍,临床疗效确切,安全性高。
经过充分的研究和不断的努力,我们创造性的发明涉及了一类具有磷酸肌酸和银杏内酯B复合结构类化合物,该类化合物不仅大大提高了银杏内酯B的水溶性和更好的抗血小板活化因子(PAF)诱导的血小板聚集作用,而且还保留了磷酸肌酸片段的心肌保护和能力补充作用,达到了完美的药效协同作用。
