基于UPLC-MS/MS和网络药理学探讨温阳通脉颗粒治疗动脉粥样硬化的物质基础和机制
Material basis and mechanism of Wenyang Tongmai Granules in the treatment of atherosclerosis based on UPLC-MS/MS and network pharmacology
采用高分辨质谱分析温阳通脉颗粒(Wenyang Tongmai Granules,WTG)的化学成分,筛选鉴定出槲皮素、阿魏酸、朝藿定B、肉桂酸、药根碱等关键活性成分,并预测其作用于动脉粥样硬化(AS)的潜在靶点共203个.通过PPI网络、GO和KEGG富集分析发现,WTG可能通过参与缺氧反应、炎症反应等生物学过程,作用于AGE-RAGE信号通路、流体剪切力与动脉粥样硬化等通路,从而干预治疗AS.关键活性成分与AS疾病靶点的分子对接显示,关键成分与炎性因子TNF-α、IL-6和PTGS2凋亡相关蛋白、CASP3等靶点具有较强的结合活性;进一步分子动力学模拟实验显示槲皮素(Quercetin)-TNF-α、肉桂酸(Cinnamic acid)-TNF-α、药根碱(Jatrorrhizine)-PTGS2和药根碱(Jatrorrhizine)-CASP3复合物在模拟中结构稳定,并保持一定的氢键相互作用,提示活性成分与靶蛋白结合良好.细胞实验表明,WTG能提高高糖损伤的血管内皮细胞存活率和SOD活性,降低LDH释放及ICAM-1、MCP-1 mRNA表达.综上,WTG通过多成分、多靶点、多通路机制干预治疗动脉粥样硬化.
Ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was employed to analyze the chemical composition of Wenyang Tongmai Granules (WTG). Key active components—quercetin, ferulic acid, epimedin B, cinnamic acid, and jatrorrhizine—were identified. A total of 203 potential targets associated with atherosclerosis were predicted. PPI network, GO, and KEGG enrichment analyses revealed that WTG likely exerted its effects by participating in biological processes such as hypoxia response and inflammatory response, as well as through pathways including the AGE-RAGE signaling pathway and fluid shear stress-related atherosclerosis pathway. Molecular docking of key active components with atherosclerosis-related disease targets demonstrated strong binding affinity between these components and inflammatory factors such as TNF-α,IL-6 and PTGS2, as well as apoptosis-related protein CASP3. Molecular dynamics simulation results indicated that small molecules—quercetin, cinnamic acid, and jatrorrhizine—exhibited favorable binding interactions with target proteins TNF-α, PTGS2, and CASP3. Cellular experiments showed that WTG could enhance the survival rate and SOD activity of vascular endothelial cells injured by high glucose, while reducing LDH release and mRNA expression of ICAM-1 and MCP-1. These findings collectively suggest that WTG exerts its anti-atherosclerotic effects through a multi-component, multi-target, and multi-pathway regulatory mechanism.
