Description

Gypensapogenin A在制备抗结核菌药物中的应用
技术领域
本发明涉及药物化合物应用领域,具体涉及Gypensapogenin A在制备抗结核菌药物中的应用。 
背景技术
近年来全球结核病的发病呈增高趋势,据世界卫生组织(WHO)估计,目前全球受结核分枝杆菌(Mycobacterium tuberculosis,MTB)感染的人口占世界人口的三分之一,其中5~10%的感染者成为结核病患者。我国每年出现活动性肺结核病人130万例,其中传染性肺结核约60万例,其中传染性肺结核约60万例,是全球结核病高负担国家之一。 
自抗结核药物相继问世,使结核病的治疗起到划时代的变化。然而由于结核病患者的治疗管理尚不十分规范,不规则化疗,滥用抗结核药物,使结核病耐药情况日益严重,且耐药性的变化更趋向于多种药物同时耐药,这给结核病的防治工作造成极大困难。因此寻找新的抗结核药物,尤其是抗多药耐药性的抗结核药物对保护人民身体健康,具有重要意义。 
发明内容
本发明涉及的化合物Gypensapogenin A是一个2012年发表(Li, N. et al., 2012. Triterpenes possessing an unprecedented skeleton isolated from hydrolyzate of total saponins from Gynostemma pentaphyllum. European Journal of Medicinal Chemistry 50, 173–178.)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人肿瘤细胞株的细胞毒活性(Li, N. et al., 2012. Triterpenes possessing an unprecedented skeleton isolated from hydrolyzate of total saponins from Gynostemma pentaphyllum. European Journal of Medicinal Chemistry 50, 173–178.),对于本发明涉及的Gypensapogenin A在制备治疗抗结核菌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,而且其对于结核菌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,同时用于结核菌感染的防治显然具有显著的进步。 
发明内容
本发明的目的在于根据现有Gypensapogenin A研究中未发现其具有抗结核活性的报道的现状,提供了Gypensapogenin A在制备抗结核菌药物中的应用。 
所述化合物Gypensapogenin A结构如式(Ⅰ)所示: 
Figure BDA0000231259641
本发明目的通过以下技术方案予以实现: 
发明人先用卡介苗做应试菌株,采用纸片扩散法对Gypensapogenin A的抗结核菌活性进行初步试验,根据初步试验的结果,本发明再用固体培养基稀释法测定了该化合物对卡介苗、结核分枝杆菌标准株H37Rv株和耐多药结核分枝杆菌(MDR MTB)三种结核菌的最小抑菌浓度,实验结果证实Gypensapogenin A具有很强的抗结核菌和抗耐药性结核菌活性,可作为治疗结核菌感染疾病的先导化合物,也可用于制备治疗结核病药物。 
与现有技术相比,本发明具有如下有益效果: 
1. 本发明提供了一种可用于抗结核病治疗的Gypensapogenin A,从而扩大了抗结核菌药物的种类; 
2. 针对目前结核病发病率高、结核杆菌多重耐药菌株及人体免疫缺陷病毒双重感染的出现,使结核病发病率和死亡率呈上升趋势的现状,本发明发现Gypensapogenin A具有抗结核菌和耐药性结核菌活性的特点,可用于抗结核药物的制备,具有非常广阔的应用前景; 
3. 本发明涉及的Gypensapogenin A在制备治疗抗结核菌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,而且其对于结核菌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,同时用于结核菌感染的防治显然具有显著的进步。 
具体实施方式
本发明所涉及化合物Gypensapogenin A的制备方法参见文献(Li, N. et al., 2012. Triterpenes possessing an unprecedented skeleton isolated from hydrolyzate of total saponins from Gynostemma pentaphyllum. European Journal of Medicinal Chemistry 50, 173–178.和Wei, J.X. et al., 1982. Two new dammaran sapogenins from leaves of Panax notoginseng. Planta Medica, 45(3): 167-171.)。
