| 目的基于网络毒理学和分子对接技术，对雷公藤有效成分中可能引起肝毒性的化合物进行预测及机制探讨。方法 2023年 1—2月，借助中药系统药理数据库和分析平台( TCMSP)、 Swiss Target Prediction数据库获取雷公藤活性成分对应靶点，运用 CTD、Genecards、OMIM等数据库获取肝毒性的相关基因靶点，将活性成分对应靶点与肝毒性相关基因靶点取交集，得到候选靶点。通过 String平台对得到的候选靶点构建蛋白质相互作用( PPI)网络，挖掘网络中核心功能模块。基于 Metascape平台，对候选靶点进行基因本体( GO)、京都基因和基因组数据库( KEGG)富集分析，并通过 CytoScape 3.9.0软件构建雷公藤活性成分 -肝毒性靶点 -通路网络，进行网络拓扑分析，筛选核心成分与靶点。结果得到 145个雷公藤主要成分产生肝毒性的候选靶点，通路富集结果显示雷公藤产生肝毒性可能与癌症途径、乙型肝炎、细胞凋亡等通路密切相关；雷公藤产生肝毒性的核心成分有雷公藤内酯甲、雷公藤内酯酮、雷公藤甲素，核心靶点有 RELA、PIK3CG、PTGS2等。结论应用网络毒理学的方法，发现雷公藤中的多种活性成分可能通过多个靶点与多条信号通路产生肝毒性。 |

| Objective To predict the possible hepatotoxic compounds in the active components of Tripterygium wilfordii and to ex-plore the mechansim based on the network toxicology and molecular docking technology.Methods From January to February 2023,pharmacology database and analysis platform of TCM system (TCMSP) and Swiss Target Prediction databases were used to obtain thecorresponding targets of the active ingredients of Tripterygium wilfordii. CTD, Genecards, OMIM and other databases were used to ob-tain the gene targets related to liver toxicity. The corresponding targets of the active ingredients and the gene targets related to liver tox-icity were intercrossed to obtain the candidate targets. The String platform was used to construct the protein-protein interaction (PPI)network for the candidate targets, and the core functional modules in the network were mined. Based on the Metascape platform, geneontology (GO) analysis and Kyoto encyclopedia of genes and genomes (KEGG) pathway analysis of the candidate targets were per-formed, and CytoScape3.9.0 software was used to construct the active ingredients-hepatotoxic target-pathway network of Tripterygium wilfordii. The network topology analysis was performed to screen the core ingredients and targets.Results A total of 145 candidate tar-gets of Tripterygium wilfordii's main ingredients causing hepatotoxicity were obtained. Pathway enrichment results showed that Tripter-ygium wilfordii's hepatotoxicity might be closely related to cancer pathway, hepatitis B, apoptosis and other pathways. The core compo-nents of Tripterygium wilfordii causing hepatotoxicity included triptolide A, triptolide one, and triptolide, and the core targets includedRELA, PIK3CG, PTGS2, etc.Conclusion With network toxicology, it was found that various active components of Tripterygium wil-fordii may produce hepatotoxicity through multiple targets and multiple signaling pathways. |
