Objective To explore the potential mechanism of Tongfengshu Tablets in treatment of gout by network pharmacology and molecular docking. Methods Key components and corresponding targets of Tongfengshu Tablets were explored by searching pharmacology analysis platform of TCM system. Target genes of gout disease were obtained by searching PharmGKB, GeneCards, OMIM, TTD, and DrugBank databases, the intersection target genes of Tongfengshu Tablets and gout were obtained by Venn package of R software. The network diagram of “TCM compound component-target” was constructed and the drug core components was screened by Cytoscape 3.8.0 software. The protein interaction network of intersecting target genes was obtained using String platform, and the core target genes were screened by Cytoscape 3.8.0 software. GO function and KEGG pathway enrichment analysis were performed on the intersection target genes by R software and molecular docking was performed by AutoDock Vina software. Results A total of 38 key components and 164 corresponding targets of Tongfengshu Tablets were excavated, 1 554 targets of gout disease were excavated, there were 66 intersection target genes. Six core components (quercetin, β-sitosterol, aloe-emodin, dinatin, eupatin, and hypolaetin) and six core target genes (RELA, IL-1β, AKT1, MAPK1, NFKBIA, and TP53) were screened out. A total of 1 963 items were enriched in GO function, including 1 830 biological processes (involving reaction to lipopolysaccharide, etc.), 27 cell components (involving membrane raft, etc.) and 106 molecular functions (involving phosphatase binding, etc.). A total of 154 items were enriched in KEGG pathway, such as interleukin (IL-17), tumor necrosis factor (TNF) and other signaling pathways. The binding energies of all core components and core target proteins were < −5 kcal/mol, and most of them were < −7 kcal/mol. Conclusion The core components of Tongfengshu Tablets, including quercetin, β-sitosterol, aloe-emotin, ect., can regulate Il-17, TNF and other signaling pathways by acting on core target genes such as RELA, IL-1β, AKT1, etc., so as to play a role in the treatment of gout.
