摘要
目的:紫草、茯苓、当归、蛇床子、冰片防治皮肤光老化作用机制的网络药理学研究。方法:利用TCMSP、TCMDatabase@Taiwan和Swiss Target Prediction数据库收集药物活性化合物及对应靶点。应用GeneCards和NCBI Gene数据库收集皮肤光老化疾病靶点。采用STRING数据库构建药物、疾病交集靶点的蛋白互作网络。应用Metascape数据库对靶点进行基因本体(gene ontology,GO)和京都基因与基因组百科全书(kyoto encyclopedia of genes and genomes,KEGG)注释分析。通过Autodock验证网络药理学分析结果。结果:通过数据库筛选得到活性成分35个,疾病相关靶点241个。药物-成分-靶点-疾病网络共涉及126个节点和387条边,通过获取网络拓扑关系获得15个重要节点。通过蛋白互作网络分析得到6个核心靶蛋白。GO富集分析获得生物过程15个条目。KEGG信号通路富集分析获得8条信号通路。分子对接结果显示活性成分与核心靶蛋白对接构象稳定。结论:5种蒙药防治皮肤光老化主要与癌症信号通路相关,其作用机制可能与调控细胞凋亡、增强氧化应激以及促进血管新生等有关。
Objective:To the mechanism of action of Radix Angelicae Sinensis,Poria,Angelica sinensis,Cnidii Fructus and Borneolum based on network pharmacology and molecular docking.Methods:The TCMSP database,TCMDatabase@Taiwan database,and Swiss Target Prediction database were used to collect the active compounds and corresponding targets of 5 Mongolian medicines.The GeneCards and the NCBI Gene database were used to collect the targets of skin photoaging diseases.The STRING database was used to construct a PPI network of the intersecting targets of herbs and disease.The Metascape database was applied for GO and KEGG pathway enrichment analysis of the targets.Molecular docking between active compounds and targets was verified by Autodock.Results:35 active ingredients and 241 disease-related targets were obtained through database screening.A total of 126 nodes and 387 edges were involved in the herbs-active compounds-targets-disease network.15 important nodes were obtained by obtaining network topology.6 important target proteins were obtained by protein interaction network analysis.15 entries of biological processes were obtained with GO enrichment analysis.KEGG signaling pathway enrichment analysis yielded 8 signaling pathways.The molecular docking results showed that the active compounds docked with the core target protein in a stable conformation.Conclusion:The mechanism of action of the 5 Mongolian medicines against skin photoaging are mainly related to cancer signaling pathway,and their mechanisms of action may be related to the regulation of apoptosis,enhancement of oxidative stress,and promotion of vascular renewal.
