摘要
目的:探讨金钗石斛生物碱抗后发性白内障的作用机制。方法:通过查阅国内外文献,收集金钗石斛生物碱类活性成分及其结构,利用网络药理学预测金钗石斛生物碱抗后发性白内障的潜在靶点,建立金钗石斛生物碱抗后发性白内障的蛋白互作关系网络(PPI),并对潜在靶点进行GO分析和KEGG通路富集分析,探索金钗石斛防治后发性白内障可能的生物进程及通路。通过分子对接验证金钗石斛生物碱与核心靶点的结合活性。结果:网络药理学分析表明,获得金钗石斛生物碱类活性成分27个,金钗石斛生物碱抗后发性白内障的核心靶点为STAT3、PIK3R1、AKT1等,GO富集分析结果表明,金钗石斛生物碱主要通过影响细胞凋亡、细胞迁移和激酶活性的双向调节等生物进程,发挥酶结合和蛋白质结合等分子结合,进而发挥抗后发性白内障的作用。金钗石斛抗后发性白内障可能与血管生成(HIF-1信号通路)、炎症反应(PI3K-Akt信号通路)等信号通路有关。分子对接结果显示金钗石斛生物碱与核心靶点均有较好的结合活性。结论:金钗石斛中石斛碱(dendrobine)、N-反式阿魏酸酰对羟基苯乙胺(N-trans-feruloyl tyramine)可能是通过STAT3、PIK3R1、AKT1等多靶点、多信号通路、多途径发挥对后发性白内障的防治作用,为后期的实验验证及金钗石斛药材的开发提供理论指导。
This paper investigates the action mechanism of Dendrobium nobile Lindl.alkaloids posterior capsular opacification.The active components of Dendrobium nobile Lindl.alkaloids and their structures are collected by reviewing domestic and foreign literature.Network pharmacology is used to predict the potential targets of Dendrobium nobile Lindl.alkaloids posterior capsular opacification,the protein interaction network(PPI)is established,and GO analysis and KEGG pathway enrichment analysis are conducted to explore the possible biological processes and pathways of Dendrobium nobile Lindl.alkaloids posterior capsular opacification.The binding activity of Dendrobium nobile Lindl.alkaloids to the core targets is verified by molecular docking.27 active ingredients of Dendrobium nobile Lindl.alkaloids are obtained,and the core targets of Dendrobium nobile Lindl.alkaloids posterior capsular opacification are STAT3,PIK3R1,AKT1,etc.The GO enrichment analysis results indicate that Dendrobium nobile Lindl.alkaloids mainly exert enzyme binding and protein binding through affecting biological processes such as apoptosis,cell migration and bidirectional regulation of kinase activity,etc.The effect of Dendrobium nobile Lindl.alkaloids posterior capsular opacification may be related to signaling pathways such as angiogenesis(HIF-1 signaling pathway)and inflammatory response(PI3K-Akt signaling pathway).The molecular docking results show that Dendrobium nobile Lindl.alkaloids have good binding activity to all core targets.In conclusion,dendrobine and N-trans-feruloyl tyramine in Dendrobium nobile Lindl.may exert their effect posterior capsular opacification through STAT3,PIK3R1,AKT1 and other targets and signaling pathways.This study has provided theoretical guidance for future validation and development of Dendrobium nobile medicines.
