本发明公开了一种薯蓣皂苷元季磷盐类衍生物及其制备方法和医药用途,所述薯蓣皂苷元季磷盐类衍生物或其药学上可接受的盐的结构如下所示:
Description
技术领域
本发明涉及医药领域,具体涉及一种薯蓣皂苷元季磷盐类衍生物及其制备方法和医药用途。
背景技术
肿瘤一直以来都是严重危害人类健康的重大疾病。2021年全球癌症会统计数据:全球新发癌症病例1929万例,其中中国新发癌症457万人,占全球23.7%。目前,大多数临床上抗肿瘤药物存在着选择性差,毒副作用大及易产生耐药性问题。因此,抗肿瘤药物的研究一直以来都是药物研发的热点之一。
线粒体是提供细胞能量代谢的细胞器,肿瘤细胞因其无限增殖分裂的特性需要消耗大量的能量和营养物质,故其线粒体的负膜电位是正常体细胞的10-100倍。且有数量多,外形短小,呈高度碎片化的特点。利用癌细胞线粒体其负电位强等特性,故一些亲脂阳离子药物对肿瘤细胞线粒体具有靶向性。
现代临床上使用的药物中,天然来源及以天然产物为先导化合物经过结构修饰和改造产生的药物超过三分之一。薯蓣皂苷元(diosgenin,DSG)是一种广泛分布于在薯蓣属植物中的,具有C27螺甾烷型的结构的甾体皂苷元,是合成各类甾体激素的重要中间体。目前研究表明其对11种肿瘤具有一定的抗肿瘤活性,具有药理作用广泛,其作用机制具有多靶点、多环节、多效应的特点。然而,薯蓣皂苷元作为潜在的抗肿瘤活性物质,同时也具生物利用度较低、细胞毒性大、适用范围相对较窄等缺点,因此需要更进一步地进行结构修饰和药理研究来提高其生物利用度及应用范围,所以如何设计改造使其抗癌活性成为了本研究迫切需要解决的问题。
