Objective To explore the potential molecular mechanism of Compound Yizhihao Granules in treatment of coronavirus disease 2019 (COVID-19) through network pharmacology and molecular docking technology. Methods The active ingredients and potential targets of Compound Yizhihao Granules were collected by applying TCMSP, BATMAN-TCM databases, and literature mining. COVID-19-related genes were collected through TTD, GeneCards, and OMMI. The intersection between the drug target of Compound Yizhihao Granules and the genes related to COVID-19 was selected, and the target protein interaction (PPI) network was constructed using String database. Through Cytoscape, a network of "drug-active ingredient-target gene-disease" was constructed. GO function and KEGG pathway enrichment analysis were performed on the intersection targets. Autodock_vina software was used for molecular docking of active ingredients and targets. A total of 92 active ingredients, 1 783 targets, and 464 COVID-19 targets were screened, and 87 potential targets were screened from the intersection of the two. 2 040 items were enriched by GO function (P < 0.05), which were related to viral processes, biological processes involved in symbiotic interactions, regulation of active oxygen metabolism, biological processes interacting with host, viral life cycle, regulation of inflammatory response and other biological processes. KEGG pathway analysis revealed a total of 150 pathways, including human cytomegalovirus infection, tuberculosis, coronavirus disease COVID-19 and IL-17 signaling pathways closely related to COVID-19. The molecular docking results confirmed that the target receptor protein could bind to the active ingredient well. Conclusion Compound Yizhihao Granules may have therapeutic effects on COVID-19 through multi-component, multi-target and multi-pathway approaches.
