摘要(Abstract):

基于网络药理学和分子对接探讨血府逐瘀汤治疗心肌梗死的作用机制。通过TCMSP平台获取血府逐瘀汤活性成分及对应靶点,借助GeneCards,DisGeNET,OMIM数据库获取心肌梗死相关靶点,对药物靶点和疾病靶点取交集,获取交集靶点。使用Cytoscape软件,构建"活性成分-靶点"网络图,利用STRING平台绘制PPI网络,使用MCODE插件进行蛋白聚类分析,利用DAVID数据库与ClueGO插件进行GO富集分析和KEGG通路分析,使用Autodock Vina和Pymol进行分子对接。最终得到血府逐瘀汤活性成分226个,对应靶点257个,心肌梗死相关靶点1 340个,药物与疾病的交集靶点109个。GO分析得到208个生物过程条目,38个分子功能条目,33个细胞成分条目;KEGG通路分析得到NF-κB信号通路、IL-17信号通路、HIF-1信号通路等相关通路。分子对接结果显示,血府逐瘀汤治疗心肌梗死的主要活性成分槲皮素、山柰酚、β-谷甾醇、木犀草素、豆甾醇、黄芩素与核心蛋白IL6,ALB,VEGFA,TNF,MAPK3,CASP3有较好的结合性。由此推测,血府逐瘀汤可能通过减少炎症反应,降低氧化应激,抑制细胞凋亡,促进血管新生,从而起到治疗心肌梗死的作用。
To explore the action mechanism of Xuefu Zhuyu Decoction in treating myocardial infarction based on network pharmaco-logy and molecular docking. Active components and corresponding targets of Xuefu Zhuyu Decoction were obtained through Traditional Chinese Medicine Systems Pharmacology Database(TCMSP), and related targets of myocardial infarction were obtained through GeneCards, DisGeNET, and OMIM databases. Then the intersection targets were obtained by integrating the drug targets and disease targets. The "active component-target" network was constructed by Cytoscape software, and protein-protein interaction(PPI) network was drawn using STRING platform. Protein cluster analysis was carried out using MCODE. GO enrichment analysis and KEGG pathway analysis were carried out using DAVID database and ClueGO, and molecular docking was carried out using Autodock Vina and Pymol. Finally, 226 active components of Xuefu Zhuyu Decoction were obtained, 257 corresponding targets, 1 340 targets of myocardial infarction, and 109 drug and disease intersection targets were obtained. From GO enrichment analysis, 208 biological process terms, 38 molecular function terms, and 33 cellular component terms were obtained. From KEGG pathway analysis, NF-κB signaling pathway, IL-17 signaling pathway, HIF-1 signaling pathway, and other related pathways were obtained. The molecular docking results showed that the main active components(quercetin, kaempferol, β-sitosterol, luteolin, stigmasterol and baicalein) of Xuefu Zhuyu Decoction in the treatment of myocardial infarction had good binding properties with the core proteins IL6, ALB, VEGFA, TNF, MAPK3 and CASP3. The results suggested that Xuefu Zhuyu Decoction may play a role in the treatment of myocardial infarction by reducing the inflammatory response, reducing oxidative stress, inhibiting cell apoptosis, and promoting angiogenesis.
