Abstract: The aim of this study is exploring the mechanism of Yupingfeng oral liquid combined Maxingshigan oral liquid and Shuanghuanglian oral liquid to treat avian respiratory tract infection via network pharmacology, and screen potential anti-IBV drugs by molecular docking technique, as well verifying the anti-IBV activity of Luteolin. The blood entry components and potential targets in three traditional Chinese medicine compounds were retrieved in TCMSP and Uniprot database. The related targets of diseases (respiratory tract infection) were discovered in DrugBank, GeneCards, OMIM and PharmGkb databases, the DAVID database was used to analyze the GO enrichment and KEGG pathway annotation. Then, the key compounds were docked with IBV-nsp9, S1 and main proteases (Mpro) by PDBQT and AutoDock vina software. The anti-IBV activity of Luteolin was validated in Vero cell. The result exhibited that Baicalein, Phillygenin, Luteolin, Formononetin, Kaempferol and Quercetin in three traditional Chinese medicine prescriptions might play a role in the treatment of avian respiratory tract infection through key targets such as FN1, IL6 and PTGS2. Molecular docking result indicated that Phillygenin, Kaempferol, Glycyrrhizin, Luteolin, Quercetin and Isovitexin showed the strongest binding ability with IBV-nsp9, S1 and Mpro. The effect of Luteolin inhibiting IBV replication and the number of viral plaques were verified in Vero cell. The study preliminarily revealed the basic pharmacological effects mechanism of three kinds of traditional Chinese medicine combinations in the treatment of avian respiratory tract infection, and confirmed the anti-IBV effect of Luteolin in vitro.
