摘要:

目的:运用网络药理学与分子对接探讨乐脉颗粒治疗血管性痴呆(VD)的作用机制。方法:通过TCMSP数据库筛选乐脉颗粒的活性成分及靶点;VD的相关靶点由GeneCardOMIMDrugBank等数据库获取,合并去重后得到交集靶点。通过Cytoscape 3.9.0软件对“药物-活性成分-靶点”网络和蛋白质-蛋白质相互作用网络进行可视化分析,得到核心活性成分和核心靶点;运用R 4.2.1软件对交集靶点进行GO分析和KEGG通路富集分析;利用AutoDock ina 1.5.6软件进行分子对接。结果:槲皮素、木犀草素、山柰酚等可能是乐脉颗粒治疗VD的核心活性成分,核心靶点包括AKT1PTGS2、肿瘤坏死因子等;GO分析主要与对肽反应、细胞对化学应激的反应等相关;KEGG主要涉及脂质与动脉粥样硬化、PI3K-Akt信号通路等。分子对接结果显示核心活性成分与核心靶点的结合活性较强。结论:乐脉颗粒通过多靶点、多通路发挥其对VD的治疗作用,其分子机制主要涉及抑制炎症反应、调节神经细胞凋亡等方面。

Abstract:

ObjectiveTo investigate the mechanism of Lemai Granules in the treatment of vascular dementiaVDusing network pharmacology and molecular docking. MethodsThe active ingredients and targets of Lemai Granules were screened from the TCMSP databaseand the relevant targets of VD were obtained from GeneCardOMIMDrugBank and other databases. The intersection targets were obtained after merging and deduplication. Cytoscape 3.9.0 software was used for visual analysis of the "drug-active ingredient-target" network and protein-protein interaction network to obtain core active ingredients and targets. R 4.2.1 software was used for GO analysis and KEGG pathway enrichment analysis of intersection targetsand AutoDock Vina 1.5.6 software was used for molecular docking. ResultsQuercetinluteolinand kaempferol may be the core active ingredients for the treatment of VD by Lemai Granulesand core targets included AKT1PTGS2and TNF. GO analysis was mainly related to peptide response and cellular responses to chemical stress. KEGG mainly involved lipid and atherosclerosisPI3K-Akt signaling pathwayand other pathways. The molecular docking results showed that the binding activity between core active ingredients and core targets was strong. ConclusionLemai Granules can exert their therapeutic effects on VD through multiple targets and pathwaysmainly involving the suppression of inflammatory reaction and the regulation of neuronal apoptosis.
