摘要:

为了探讨了绞股蓝防治糖尿病的作用机制,本研究利用网络药理学和分子对接方法,对绞股蓝的有效成分及药理作用进行研究。本研究通过TCMSP、SwissTargetPrediction和GeneCards等数据库,分别检索并筛选得到20个绞股蓝有效成分和155个绞股蓝防治糖尿病的潜在作用靶点,再经STRING数据库进行蛋白-蛋白互作筛选,得57个关键靶点。通过GO富集和KEGG通路分析,得到20个生物过程、20个分子功能、17个细胞组分,以及20条主要的信号通路,涉及到12个绞股蓝有效成分和53个关键靶点。分子对接结果表明高圣草酚、鼠李秦素与MAPK8、PIK3CA等关键靶点结合自由能较低。总之,绞股蓝防治糖尿病的主要机制可能通过PI3K-Akt以及胰岛素抵抗等信号通路来调控胰岛素以及相关细胞增殖、凋亡和迁移等生物学过程进而达到防治糖尿病的目的。

Abstract:

To explore the mechanism of G. pentaphyllum in the prevention and treatment of diabetes,this study employed network pharmacology and molecular docking methods to investigate the effective ingredients and pharmacological effects of G. pentaphyllum.Through databases such as TCMSP,SwissTargetPrediction,and GeneCards,20 active ingredients of G. pentaphyllum and 155 potential targets in the prevention and treatment of diabetes were retrieved and screened.Subsequently,using the STRING database,57 key targets were obtained through protein-protein interaction screening.GO enrichment and KEGG pathway analysis identified 20 biological processes,20 molecular functions,17 cell ingredients,and 20 major signaling pathways involving 12 active ingredients of G. pentaphyllum and 53 key targets.Molecular docking results indicated that 3′-methyleriodictyol and Rhamnazin exhibited lower binding free energy with key targets such as MAPK8 and PIK3CA.In conclusion,the main mechanism of G. pentaphyllum in the prevention and treatment of diabetes may involve regulating insulin and related cellular proliferation,apoptosis,and migration processes through signaling pathways such as PI3K-Akt and insulin resistance.
