Objective To explore the potential mechanism of emodin in treatment of acute pancreatitis by network pharmacology, GEO sequencing data, and molecular docking. Method Emodin targets were obtained from PubChem, SwissTargetPrediction, DrugBank, PharmMapper, TTD, and CTD databases. The disease targets of acute pancreatitis were obtained from GeneCards, OMIM, DrugBank, CTD, and GSE194331 data sets. The intersection of the two data sets was used to obtain emodin targets for acute pancreatitis. The target protein interaction network was constructed using String database and Cytoscape software, R software ClusterProfiler package was used for target enrichment analysis, and Cytoscape CytoNCA plug-in was used to screen core targets. Molecular docking and result visualization were performed using PyMOL and Autodock software. Results There are 246 potential targets of emodin in treatment of acute pancreatitis, mainly involving lipids and atherosclerosis, P13K-Akt signaling pathway, FoxO signaling pathway, HIF-1 signaling pathway and IL-17 signaling pathway. Among them, 20 core targets showed good binding potential with emodin, and 9 targets including CTNNB1, HIF1A and IL1B showed good binding potential with emodin. Conclusion Emodin plays a role in treatment of acute pancreatitis through multi-target and multi-pathway.
