[Abstract]
Objective To study the potential mechanism of geniposide in treatment of cerebral ischemia by network pharmacology and molecular docking. Methods PubChem, PharmMapper, GeneCards, and OMIM databases were used to predict the targets of geniposide and disease respectively. Venny 2.1.0 tool was used to obtain the intersection of the two targets, and the protein interaction network of the intersection targets was constructed through STRING database. Cytoscape 3.7.2 software was used to analyze the network topology of the core target. GO and KEGG gene enrichment analysis was carried out based on the core target genes. AutodockTool software was used to dock the selected core targets with geniposide. Results The protein interaction network of intersection targets was constructed by STRING database, and 173 intersection targets were obtained, including SRC, AKT1, HSP90AA1, PIK3R1, EGFR, etc. Geniposide may regulate PI3K-Akt signaling pathway, AGE-RAGE signaling pathway in diabetic complications, fluid shear stress and atherosclerosis pathway, Ras in treatment of cerebral ischemia signaling pathway and other signaling pathways play a role in the treatment of cerebral ischemia. Conclusion This study predicts the potential mechanism of geniposide in the treatment of cerebral ischemia, and provides theoretical basis and research direction for subsequent experimental research.
