目的:本研究通过整合网络药理学与分子对接技术,解析苓术汤治疗2型糖尿病(T2DM)的作用机制,明确其药效物质基础及核心靶点,为临床应用提供科学依据。方法:利用TCMSP数据库筛选苓术汤中10味中药的活性成分,于Uniprot数据库筛选对应靶点。随后于GeneCards、DisGeNet等数据库获取T2DM疾病基因靶点,与药物靶点取交集确定共同作用靶点。利用Cytoscape软件构建“活性成分-疾病靶点”网络。利用String数据库进行PPI网络分析并得出关键靶点基因。将共同交集靶点引入R软件进行GO/KEGG富集分析。最后,进行关键成分与靶点的分子对接及分子动力学模拟验证。结果:共筛选到181个活性成分及228个潜在靶点,其中交集得到165个共同作用靶点。多维网络分析揭示槲皮素、大豆异黄酮等关键成分及CTNNB1、FOS等8个核心靶点。GO富集显示靶点显著关联脂质代谢、炎症反应等生物学过程;KEGG分析表明核心通路包括PI3K-Akt信号通路及脂质与动脉粥样硬化相关通路。分子对接及分子动力学模拟证实黄芩苷与FOS蛋白结合具有较强稳定性。结论:苓术汤通过多种途径发挥抗T2DM作用,其核心机制涉及细胞相关作用及PI3K-Akt通路、脂质代谢调控。本研究为苓术汤的临床应用及后续研究提供了药效机制支持。

基于网络药理学、分子对接及分子动力学模拟探讨苓术汤治疗2型糖尿病机制
Objective: This study analyzed the mechanism of action of Lingzhu decoction in the treatment of type 2 diabetes mellitus (T2DM) by integrating network pharmacology and molecular docking technology, and clarified its pharmacodynamic material basis and core targets, so as to provide scientific basis for clinical application.Methods: The TCMSP database was used to screen the active constituents of the ten Chinese medicines in Lingzhu decoction, and the corresponding targets were screened in the Uniprot database. Subsequently, the T2DM gene targets were obtained from the GeneCards and DisGeNet databases, and the intersection with the drug targets was taken to determine the common target of action. The active ingredient-diseasetarget pharmacodynamic network construction relied on Cytoscape software. Utilize the String database to conduct PPI network analysis and derive the key target genes. Introduced the co-intersected targets into R software for GO/KEGG enrichment analysis. Finally, molecular docking and molecular dynamics simulation of key components and targets were performed for validation.Results: A total of 181 active ingredients and 228 potential targets were screened out, of which 165 co-interacting targets were intersected. Multidimensional network analysis revealed key components such as quercetin and soy isoflavones, as well as eight core targets including CTNNB1 and FOS. GO enrichment showed that the targets were significantly associated with lipid metabolism, inflammation and other biological processes, and KEGG analysis showed that the core pathways included PI3K-Akt signaling pathway and lipids and atherosclerosis-related pathways. Molecular docking and molecular dynamics simulations confirmed the strong stability of baicalin binding to FOS protein.Conclusion: Lingzhu decoction exerts anti-T2DM effects through multiple pathways, and its core mechanism involves cell-related effects and regulation of PI3K-Akt pathway and lipid metabolism. The study provides pharmacological mechanism support for the clinical application and subsequent research of Lingzhu decoction.
