摘要
目的 采用UPLC-Q-TOF-MS和网络药理学方法,从分子水平揭示苦参经皮给药对湿疹的潜在作用机制。方法 采用UPLC-Q-TOF-MS技术,结合文献数据鉴定化学成分。通过Swiss Target Prediction数据库预测作用靶点,Cytoscape 3.9.0构建蛋白质互相作用(PPI)网络图,利用Metascape数据库对靶点进行GO注释和KEGG通路分析。结果 小鼠经皮给药后推测出14个皮肤滞留原形成分,7个入血原形成分。网络药理学研究得到肿瘤坏死因子(TNF)、血管内皮生长因子A(VEGFA)、表皮生长因子受体(EGFR)等苦参治疗湿疹的核心靶点。KEGG富集分析显示与血清素能突触信号通路、花生四烯酸代谢等信号途径密切相关。结论 通过UPLC-Q-TOF-MS结合网络药理学进一步阐明苦参外用治疗湿疹的主要靶点和通路,为后续深入研究提供参考。
Objective To determine the potential mechanism of transdermal administration of Sophora flavescens on eczema at molecular level with UPLC-Q-TOF-MS and network pharmacology.Methods The chemical compositions were identified by UPLC-Q-TOF-MS technique and literature data.The target was predicted by Swiss Target Prediction database,the protein interaction(PPI)network map was established by Cytoscape 3.9.0,and the target was analyzed by GO annotation and KEGG pathway with Metascape database.Results After transdermal administration of the drug in mice,14 components of the skin retention prototype and 7 components of the blood prototype were inferred.The core targets of Sophora flavescens treatment for eczema,such as tumor necrosis factor,vascular endothelial growth factor A and epidermal growth factor receptor,were identified by network pharmacology.KEGG enrichment analysis showed close relation to serotonergic synaptic signaling pathway and arachidonic acid metabolism.Conclusion UPLC-Q-TOF-MS combined with network pharmacology is used to further elucidate the main targets and pathways of Sophora flavescens for the treatment of eczema.
