文题释义:

中药计算机模拟:指应用化学空间、分子对接、生物网络等计算机方法,模拟中药的药效物质基础及药代动力学等。
系统描述雷公藤中不同化合物在治疗类风湿关节炎中的作用:通过计算机模拟方法,从分子水平直观展示了雷公藤中不同化合物与类风湿关节炎治疗靶点的相互作用,明确了其药效物质基础和作用靶点,揭示了其治疗类风湿关节炎作用机制可能是通过抗炎、调节免疫应答、抑制软骨和骨的破坏、改善类风湿关节炎血瘀证,上述为从雷公藤中寻找新的类风湿关节炎治法和新药开发奠定基础。

 

背景:雷公藤及某些单体在治疗类风湿关节炎上临床效果确切,而较为系统探讨雷公藤药效物质基础与分子作用机制的研究较少。
目的:探讨雷公藤治疗类风湿关节炎的药效物质基础与分子作用机制。
方法:借助Discovery Studio 4.0模拟平台,构建雷公藤化学成分分子数据集,比较其与Therapeutic Target Database中类风湿关节炎治疗药物分子的化学空间,在此基础上,采用网络药理学方法探讨其与类风湿关节炎治疗靶点的相互作用。

结果与结论:雷公藤分子与类风湿关节炎药物分子具有相似的化学空间,其药效物质基础含有苯乙烯南蛇碱、表没食子儿茶精、雷公藤新碱和雷公藤甲素等46个化合物,可作用于肿瘤坏死因子α、JAK-1、基质金属酶1、基质金属酶3和基质金属酶9等10个靶点,来抗炎、调节免疫应答、抑制软骨和骨的破坏、改善类风湿关节炎血瘀证。计算机模拟直观展示了雷公藤治疗类风湿关节炎的多成分、多靶点、多途径作用。

Abstract:

BACKGROUND: Tripterygium wilfordii and its certain monomers have exact clinical effects on rheumatoid arthritis. However, there are few studies about a systematic discussion on pharmacodynamic material basis and molecular mechanism of Tripterygium wilfordii.
OBJECTIVE: To explore the pharmacodynamic material basis and molecular mechanism of Tripterygium wilfordii in treating rheumatoid arthritis.
METHODS: Based on the platform of Discovery Studio 4.0, the molecular set of Tripterygium wilfordii was built and compared with the rheumatoid arthritis drug set from Therapeutic Target Database in chemical space. After that, network pharmacology was used to explore the interactions of Tripterygium wilfordii and therapeutic targets related to rheumatoid arthritis.
RESULTS AND CONCLUSION: The molecular sets of Tripterygium wilfordii and drugs for treating rheumatoid arthritis had similar chemical space. The pharmacodynamic material basis of Tripterygium wilfordii had 46 compounds, such as celacinnine, epigallocatechin, euonine, triptolide. They could mediate inflammation, regulate immune response, inhibit cartilage and bone destruction, improve blood stasis-type rheumatoid arthritis by acting on 10 targets, such as tumor necrosis factor-α, JAK-1, matrix metalloproteinase-1, matrix metalloproteinase-3, matrix metalloproteinase-9. Computer simulation could intuitively trace out the multi-ingredient, multi-target and multi-pathway effects of Tripterygium wilfordii.
