Description

Lycojaponicumin B在制备治疗肾癌药物中的应用
技术领域
本发明涉及化合物LycojaponicuminB的新用途,尤其涉及LycojaponicuminB在制备抗肾癌药物中的应用。
技术背景
癌症是对人类生命健康危害最大的疾病之一,每年都有大量的人死于癌症。抗癌药物的研发一直是药学研究的热点。抗肿瘤药物中有74%是天然产物或其衍生物,如紫杉醇及其衍生物就是目前临床上应用效果比较好的抗肿瘤药物。因此,从天然产物中寻找抗癌化合物或先导化合物具有重要的意义。
本发明涉及的化合物LycojaponicuminB是一个2012年发表(Wang,X.J.etal.,2012.LycojaponicuminsA-C,ThreeAlkaloidswithanUnprecedentedSkeletonfromLycopodiumjaponicum.OrganicLetters14(10),2614-2617.)的新骨架化合物,该化合物拥有全新的骨架类型,对于本发明涉及的LycojaponicuminB在制备治疗肾癌药物中的用途属于首次公开,由于骨架类型属于全新的骨架类型,而且其对于肾癌细胞的抑制活性强得意想不到,不存在由其他化合物给出任何启示的可能,具备突出的实质性特点,同时用于肾癌的防治显然具有显著的进步。
发明内容
本发明提供化合物LycojaponicuminB在制备抗肿瘤药物中的应用。
本发明采用如下技术方案:LycojaponicuminB在制备抗肾癌药物中的应用,LycojaponicuminB的结构式如式(Ⅰ)所示:
本发明通过体外MTT抗肿瘤活性评价发现,LycojaponicuminB对人肾癌细胞株KC的生长也具有显著的抑制作用,抑制这1株细胞生长的IC50值为1.29±0.12μM。因此,LycojaponicuminB能用于制备抗肾癌药物,具有良好的开发应用前景。
本发明涉及的LycojaponicuminB在制备治疗肾癌药物中的用途属于首次公开,由于骨架类型属于全新的骨架类型,而且其对于肾癌细胞的抑制活性强得意想不到,不存在由其他化合物给出任何启示的可能,具备突出的实质性特点,同时用于肾癌的防治显然具有显著的进步。
以下通过实施例对本发明作进一步详细的说明,但本发明的保护范围不受具体实施例的任何限制,而是由权利要求加以限定。
具体实施方式
本发明所涉及化合物LycojaponicuminB的制备方法参见文献(Wang,X.J.etal.,2012.LycojaponicuminsA-C,ThreeAlkaloidswithanUnprecedentedSkeletonfromLycopodiumjaponicum.OrganicLetters14(10),2614-2617.)。
以下通过实施例对本发明作进一步详细的说明,但本发明的保护范围不受具体实施例的任何限制,而是由权利要求加以限定。
实施例1:本发明所涉及化合物LycojaponicuminB片剂的制备:
取20克化合物LycojaponicuminB,加入制备片剂的常规辅料180克,混匀,常规压片机制成1000片。
实施例2:本发明所涉及化合物LycojaponicuminB胶囊剂的制备:
取20克化合物LycojaponicuminB,加入制备胶囊剂的常规辅料如淀粉180克,混匀,装胶囊制成1000片。
下面通过药效学实验来进一步说明其药物活性。
实验例:采用MTT法评价化合物LycojaponicuminB对人肾癌细胞株的生长抑制作用
1.方法:处于生长对数期的细胞:人肾癌细胞株KC(购买自中国科学院细胞库)以1.5×104浓度种于96孔板中。细胞培养24h贴壁后吸去原来的培养基。试验分为空白对照组、药物处理组。空白组更换含10%胎牛血清的1640培养基;药物处理组更换含浓度为100μM,50μM,10μM,1μM,0.1μM,0.01μM,0.001μM,0.0001μM和0.00001μM的LycojaponicuminB的培养基。培养48h后,加入浓度5mg/mL的MTT,继续放于CO2培养箱培养4h,然后沿着培养液上部吸去100μL上清,加入100μLDMSO,暗处放置10min,利用酶标仪(Sunrise公司产品)测定吸光值(波长570nm),并根据吸光值计算细胞存活情况,每个处理设6个重复孔。细胞存活率(%)=ΔOD药物处理/ΔOD空白对照×100。
2.结果:LycojaponicuminB对人肾癌细胞株KC的生长具有显著的抑制作用。该化合物抑制人肾癌细胞株KC生长的IC50值分别为:1.29±0.12μM。
由上述实施例表明,本发明的LycojaponicuminB对人肾癌细胞株KC的生长具有很好的抑制作用。由此证明,本发明的LycojaponicuminB具有抗肾癌活性,能用于制备抗肾癌药物。
