Abstract: 【Objective】 The purpose of this study was to discover the target and mechanism of curcumol against Encephalomyocarditis virus (EMCV) using network pharmacology and molecular docking technology.【Method】 The potential targets of curcumol against EMCV were obtained through PharmMapper and GeneCards databases.Cytoscape 3.7.2 software, STRING and DAVID databases were used to construct the target protein-protein interaction (PPI) network to screen the key targets.GO function and KEGG pathway enrichment analysis were carried out for the target proteins.Network model of curcumol anti-EMCV targets pathway was constructed.The binding energy and binding mode of curcumol with target protein were analyzed by AutoDock Vina 1.1.2.【Result】 The results of network analysis showed that there were 9 potential targets of curcumol anti-EMCV.Mitogen-activated protein kinase 14 (MAPK14), signal transducer and activator of transcription 1 (STAT1), albumin (ALB) and interleukin 2 (IL2) might be the core targets of curcumol anti-EMCV.The targets participated in metabolic pathways such as C-type lectin receptor, neurotrophin and JAK-STAT signaling pathways, and their function involved regulation of cytokine production in inflammatory response, protein kinase activity and drug binding etc.Molecular docking showed that there was strong binding energy between the four core target proteins and curcumol.There was hydrophobic binding between the core target proteins and curcumol, and there was hydrogen bond binding between ALB, STAT1 and IL2 with curcumol.【Conclusion】The results of this study indicated that, curcumol might play the anti-EMCV role by acting on the key protein of MAPK14, STAT1, ALB and IL2.This study provided theoretical basis and clues for the research and development of curcumol as an anti-EMCV drug.
