摘要(Abstract):

通过网络药理学和分子对接的方法研究麻黄连翘赤小豆汤治疗湿疹(eczema)的作用机制。首先利用TCMSP数据库挖掘麻黄连翘赤小豆汤中各个药物的活性成分并预测其作用靶点,借用Uniprot数据库将靶点蛋白名称标准化。然后通过GeneCards,OMIM,PharmGkb,DrugBank等数据库获得湿疹的疾病靶点。取药物靶点与疾病靶点共同作用的潜在靶点制作韦恩图,运用Cytoscape 3.6.1软件筛选并构建"活性成分-核心靶点"网络,利用STRING数据库构建蛋白互作(protein-protein interaction,PPI)网络,利用R语言对核心作用靶点进行GO富集分析和KEGG通路分析。最后通过AutoDock软件对药物的主要活性成分及核心作用靶点进行分子对接验证。研究结果显示,筛选得到麻黄连翘赤小豆汤治疗湿疹的活性成分74个及靶点103个,主要活性成分为槲皮素、木犀草素、汉黄芩素、山柰酚等,主要靶点为PTGS1,ESR1,PPARG,MAPK3等,PPI网络主要计算出MAPK8,MAPK3,JUN,MAPK14,TP53,MAPK1,ESR1,RELA等8个关键靶点。GO富集分析共涉及到生物过程2 024个,细胞组分81个,分子功能140个,KEGG通路富集分析筛选得到158条与湿疹相关通路,主要作用于AGE-RAGE信号通路、IL-17信号通路、病毒相关通路等。分子对接结果表明,主要活性化合物能够分别与代表性的靶点结合并展现出较好的亲和力。该研究表明麻黄连翘赤小豆汤治疗湿疹涉及多条信号通路及生物学过程,其主要活性成分槲皮素、木犀草素、汉黄芩素、山柰酚与关键靶点MAPK8,MAPK3,JUN,MAPK14,TP53,MAPK1,ESR1,RELA结合可能是发挥作用的重要机制之一。
To study the molecular mechanism of Mahuang Lianqiao Chixiaodou Decoction in the treatment of eczema by means of network pharmacology and molecular docking. First, the TCMSP database was used to excavate the active ingredient of each drug in Mahuang Lianqiao Chixiaodou Decoction and predict its target, and the Uniprot database was used to standardize the names of target proteins, in order to obtain the disease targets of eczema through GeneCards, OMIM, PharmGkb, DrugBank and other databases. And next, the potential targets on which drug targets and disease targets work together were selected to make a Venn diagram, the Cytoscape 3.6.1 software was used to screen out and construct the "active ingredient-core targets" network. STRING database was used to construct a protein-protein interaction(PPI) network, and the R language was used to perform GO enrichment analysis and KEGG pathway analysis. Finally, the molecular docking verification of main active ingredients and core targets of the drug was performed by AutoDock software. The study showed that 74 active ingredients and 103 targets of Mahuang Lianqiao Chixiaodou Decoction for the treatment of eczema were screened. The main active ingredients included quercetin, luteolin, wogonin, kaempferol, and the main targets included PTGS1, ESR1, PPARG, and MAPK3. In addition, eight key targets, including MAPK8, MAPK3, JUN, MAPK14, TP53, MAPK1, ESR1 and RELA, were calculated by PPI network. GO enrichment analysis involved 2 024 biological processes, 81 cell components, and 140 molecular functions. KEGG pathway enrichment analysis was performed to screen out 158 eczema-related pathways, which mainly acted on AGE-RAGE signaling pathway, IL-17 signaling pathway, virus-related pathways, and the results of molecular docking showed that the main active compounds could respectively bind to representative targets and exhibit a good affinity. The study proved that the treatment of eczema with Mahuang Lianqiao Chixiaodou Decoction involved multiple signaling pathways and biological processes, and the combination of main active ingredients(such as quercetin, luteolin, wogonin, kaempferol) and key targets(such as MAPK8, MAPK3, JUN, MAPK14, TP53, MAPK1, ESR1, RELA) may be one of the important mechanisms of action.
