摘要
目的:采用网络药理学方法对龙胆裂环环烯醚萜类成分药效作用进行分析,探讨其可能的分子机理。方法:将5种龙胆裂环环烯醚萜类成分结构导入Pharm Mapper进行靶点匹配与预测,将所得靶点信息导入DAVID,富集分析靶点所涉及的GO生物过程与KEGG pathway通路;利用String10与Cytoscape 3.2.1构建靶点蛋白相互作用网络。结果:共得到251个作用靶点,主要富集于蛋白磷酸化等生物学过程以及MAPK信号途径等共26条通路中。蛋白相互作用网络分析表明跨膜受体蛋白酪氨酸激酶信号途径在龙胆药效作用过程中起重要作用。结论:龙胆裂环环烯醚萜类有效成分可能是通过跨膜受体酪氨酸激酶-Ras-MAPK信号传递途径,调控靶点蛋白磷酸化水平,进而影响其他信号通路及代谢途径,最终达到保肝、利胆、健胃、抗炎等功效的。
Objective:In order to reveal the molecular mechanism of secoiridoids isolated from Gentianae Radix et Rhizoma, this study established an interaction networks based on network pharmacology. Methods:Input the file of structure into PharmMapper to get targets of secoiridoids, then maked the enrichment analysis of GO and KEGG Pathway by DAVID, and established "compound-target-pathway" network by String 10 and Cytoseape. Resuhs:251 proteins were matched to the secoiridoids. Based on the enrichment analysis, the main effect of targets were protein amino acid phosphorylation, MAPK singaling pathway, et al., and the most important were transmembrane receptor protein tyrosine kinase signaling pathway. Conculsions The seeoiridoids were able to effect "transmembrane receptor protein tyrosine kinase-Ras-MAPK" signaling pathway, regulate protein phosphorylation, and cure the disease.
