摘要
目的利用网络药理学结合分子对接技术探讨昆明山海棠引起不良反应的毒性机制。方法系统检索昆明山海棠文献,全面筛选其活性成分并汇总相关不良反应,通过中药系统药理学数据库与分析平台、Swiss数据库以及STITCH数据库预测昆明山海棠活性成分-作用靶点,利用美国比较毒理基因组学数据库建立不良反应-作用靶点。合并获得交集基因,将相关毒性潜在靶点导入STRING数据库获取蛋白相互作用,利用DAVID平台进行GO生物功能过程和KEGG代谢通路富集分析。利用Systems Dock平台将昆明山海棠的特征性成分与关键毒性靶点进行分子对接。结果筛选得到21个昆明山海棠的生物活性成分,通过构建毒性蛋白相互作用关系(PPI)网络获取相关毒性靶点47个。对毒性靶点PPI网络的富集分析结果显示,昆明山海棠的毒性靶点可能与p53信号通路、PI3K-Akt信号通路等密切相关。分子对接研究证实昆明山海棠中大多数活性成分与毒性靶点有着较好的结合活性。结论初步验证了昆明山海棠引起不良反应的毒性机制,为进一步开展毒性中药致不良反应的作用机制研究提供了新思路和新方法。
Objective To explore the potential toxicity mechanism of Kunming shanhaitang(Tripterygium Hypoglaucum Toot, Radix Tripterygium Hypoglaucum) with methods of network pharmacology and molecular docking. Methods Literature on Kunming shanhaitang was first comprehensively searched to identify and collect its active ingredients and adverse drug reactions(ADRs), respectively. Targets of the active ingredients were then predicted with TCMSP, Swiss, and STITCH databases. Moreover, targets of ADRs were gathered through CTD database. Next, the common genes shared by the above two types of targets were submitted to STRING to obtain protein-protein interaction. In addition, GO biological function process and KEGG pathway enrichment analysis were conducted on DAVID platform. Finally, molecular docking was carried out between characteristic ingredients of the herb and its key toxicity targets with systemsDock Web Site. Results A total of 21 ingredient candidates of Kunming shanhaitang involving 47 toxicity targets were identified by establishing toxic protein-protein interaction(PPI) network. PPI network enrichment analysis of the toxicity targets showed that such targets were probably closely associated with the p53 signaling pathway, PI3 K-Akt signaling pathway and some other pathways. According to the results of molecular docking, the majority of the active ingredients in the medicinal herb enjoyed good binding activities with the toxicity targets. Conclusion This research verified preliminarily the toxicity mechanism of Kunming shanhaitang, providing new ideas and methods for further research on the toxicity mechanism of ADRs of Chinese medicinal herbs with toxicity.
