Description

Houttuynoid D在治疗肾癌药物中的应用
技术领域
本发明涉及化合物Houttuynoid D的新用途,尤其涉及HouttuynoidD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Houttuynoid D是一个2012年发表(Chen, S.D. et al., 2012. Houttuynoid D_E, Anti-Herpes SimplexVirus Active Flavonoids with Novel Skeletons from Houttuynia cordata. Organic Letters 14 (7), 1772–1775.)的新骨架化合物,该化合物拥有全新的骨架类型,目前的用途仅仅涉及抗单纯疱疹病毒活性(Chen, S. D. et al., 2012. Houttuynoid D_E, Anti-Herpes Simplex Virus Active Flavonoids with Novel Skeletons from Houttuynia cordata. Organic Letters 14 (7), 1772–1775.),对于本发明涉及的Houttuynoid D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Houttuynoid D在制备抗肿瘤药物中的应用。
本发明采用如下技术方案:Houttuynoid D在制备抗肾癌药物中的应用,Houttuynoid D的结构式如式(Ⅰ)所示:
Figure BDA0000231837941
本发明通过体外MTT抗肿瘤活性评价发现,Houttuynoid D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值分别为1.73±0.22 μM。因此,Houttuynoid D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Houttuynoid D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Houttuynoid D的制备方法参见文献(Chen, S. D. et al., 2012. Houttuynoid D_E, Anti-Herpes Simplex Virus Active Flavonoids with Novel Skeletons fromHouttuynia cordata. Organic Letters 14 (7), 1772–1775.)。
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Houttuynoid D片剂的制备:
取20克化合物Houttuynoid D,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Houttuynoid D胶囊剂的制备:
取20克化合物Houttuynoid D,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Houttuynoid D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24 h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100 μM,50 μM,10 μM,1 μM,0.1 μM,0.01 μM,0.001 μM,0.0001μM和0.00001 μM 的Houttuynoid D的培养基。培养48 h后,加入浓度5mg/mL的MTT,继续放于CO2培养箱培养4 h,然后沿着培养液上部吸去100 μL上清,加入100 μL DMSO,暗处放置10 min,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:Houttuynoid D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:1.73±0.22 μM。
由上述实施例表明,本发明的Houttuynoid D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Houttuynoid D具有抗肾癌活性,能用于制备抗肾癌药物。
