Abstract
本发明属医药领域,涉及联苯类化合物4‑(3',4'‑二羟苯基)肉桂酸在制备抗乙肝病毒和抗补体药物中的用途。本发明从山芝麻属植物山芝麻的干燥根中分离得到1个联苯类化合物,并经试验证实其具有较强的抗乙肝病毒活性,且有效浓度低,对HBsAg的IC50值为18.4μg/ml,显著高于阳性对照拉米呋啶,当在最大无细胞毒浓度50μg/ml时,对HBeAg的抑制率为34.5%;另外,经体外抗补体活性测定结果显示其对补体系统经典途径和旁路途径补体激活有很强的抑制作用,对补体系统经典途径补体激活的CH50值为0.0022mg/ml,对旁路途径激活的AP50值为0.0057mg/ml。所述的化合物可进一步用于制备抗乙肝病毒药物和制备抗补体药物。
Description
技术领域
本发明属医药领域,涉及一种从药用植物山芝麻中分离得到的联苯类化合物4-(3',4'-二羟苯基)肉桂酸在制药中的用途,尤其是在制备抗乙肝病毒药物和抗补体药物中的用途。
背景技术
据有关统计显示,全世界大约有3亿多人为慢性乙肝病毒(HBV)携带者,我国约占半数。乙肝病毒感染已成为全球性的影响人类健康的主要疾病之一,由于HBV感染可以导致慢性肝炎、肝硬化和原发性肝癌,因此成为影响人类寿命的九大疾病之一。由于慢性HBV感染者较非携带者发生肝癌的相对危险率为217,因此在全世界每年大约有200万人死于乙肝引起的肝硬化和肝癌,而我国是乙型肝炎的高发区,每年约有25万人死于与乙肝相关的慢性肝病(肝硬化与肝癌)。上述疾病给人民健康和国民经济带来巨大损失。因此,寻求高效低毒的抗HBV药物已成为刻不容缓的问题。
现有技术公开了补体系统的过度激活会引发系统性红斑狼疮、类风湿性关节炎、急性呼吸窘迫综合征等多种重大疾病。然而目前临床实践中对此类疾病尚缺乏较为理想的治疗药物,因此临床上急需高效、低毒、专一的新型补体抑制剂。从天然产物中研究开发补体抑制剂是近年来一个受到越来越多关注的重要研究领域,其具有成本低、毒性小等特点。国内外学者已从包括海洋生物在内的多种天然产物中分离得到多种具有补体系统抑制作用的单体化合物,为抗补体药物的研究与开发提供了广阔的前景。
山芝麻为梧桐科植物山芝麻(Helicteres angustifolia L.)的干燥根或全株,味苦、性寒,归肺、大肠经,可解表清热、解毒消肿,用于治疗感冒发热、痄腮、乳娥、麻疹、咳嗽、泄泻痢疾、痈肿。现代药理研究表明山芝麻具有抗菌、抗炎、抗病毒及抗肿瘤等活性。
目前尚未见本发明中涉及的联苯类化合物4-(3',4'-二羟苯基)肉桂酸的抗HBV
和抗补体活性报道,本申请的发明人拟提供山芝麻在制药中的新的用途。
发明内容
本发明的目的是提供一种从山芝麻中分离得到的联苯类化合物4-(3',4'-二羟苯基)肉桂酸。
本发明的进一步目的在于提供上述化合物作为制备抗乙肝病毒药物中的用途。
本发明的进一步目的还在于提供上述化合物作为制备抗补体药物中的用途。
本发明从山芝麻属植物山芝麻(H.angustifolia)干燥根的乙醇提取物乙酸乙酯萃取部位中分离得到1个联苯类化合物,应用现代药理研究方法,对分离得到的单体化合物进行体外抗HBV和抗补体活性评价,证实其具有较强的抗HBV活性以及对补体系统经典途径和旁路途径的补体激活均有较强的抑制作用。
本发明所述的联苯类化合物具有以下化学结构:
本发明所述的化合物通过下述方法制备:
取山芝麻干燥根25kg,粉碎,用95%乙醇回流提取3次(50L×3),每次2h,合并提取液并浓缩得浸膏0.95kg,加水(4L)混悬,分别以等体积石油醚、乙酸乙酯和正丁醇萃取5次,合并萃取液并浓缩至干,得乙酸乙酯萃取物200g。将乙酸乙酯萃取部位经硅胶(200-300目)柱色谱分离,依次以二氯甲烷-甲醇(50:1-0:1)梯度洗脱,得到11个流份(Fr.1-11),其中流份Fr.3(32g)再经硅胶柱色谱(二氯甲烷-甲醇,30:1,20:1,10:1,5:1,3:1,1:1)、MPLC(甲醇-水,20:80-80:20梯度洗脱)和半制备HPLC等手段纯化,分离得到化合物4-(3',4'-二羟苯基)肉桂酸[4-(3',4'-dihydroxyphenyl)cinnamic acid]。
本发明制得的化合物4-(3',4'-二羟苯基)肉桂酸可进一步用于制备抗乙肝病毒药物和制备抗补体药物。

应用Hep G2的2.2.15细胞株(教育部/卫生部医学分子病毒学重点实验室,上海),以每孔10×105个细胞接种于24孔板,培养基为DMEM,生长液含10%胎牛血清,380μg/mlG418,0.03%谷胺酰胺,青霉素、链霉素各100μg/ml,在5%CO2孵箱中37℃培养,48小时后,换成二甲基亚砜助溶的含药物的培养液,每种药物设3~5个浓度,每个浓度设4个平行孔,继续培养9天(每3天换液一次),收集上清液用ELISA检测HBsAg及HBeAg含量。同样条件下以不含药物的培养液上清液作为对照组。同时用上述细胞株,用MTT法测定药物的细胞毒性。阳性对照为拉米呋啶(3TC)。结果证实本发明所述化合物具有很强的抗HBV活性,且有效浓度低,对HBsAg的IC50值为18.4μg/ml,显著高于阳性对照拉米呋啶(3TC),当在最大无细胞毒浓度50μg/ml时,对HBeAg的抑制率为34.5%(如表1所示)。
