[Abstract]
Objective To explore the Mechanism of Cangerzi Powder in treatment of allergic rhinitis based on network pharmacology and molecular docking. Methods TCMSP, Gene Cards and OMIM database were used to screen out the common targets of Cangerzi Powder and allergic rhinitis, so as to obtain the potential targets of Cangerzi Powder in treatment of allergic rhinitis. Potential targets of Cangerzi Powder in treatment of allergic rhinitis were introduced into the STRING platform, and core targets were selected by constructing the protein interaction (PPI) network through Cytoscape 3.7.1 software. DAVID database was used for gene ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of potential targets of Cangerzi Powder in treatment of allergic rhinitis. AutoDock Vina 1.1.2 software was used for molecular docking of key components and key targets. Results A total of 62 active ingredients of Cangerzi Powder were collected, and 214 common targets of Cangerzi Powder and allergic rhinitis were identified, among which MAPK3, STAT3, and AKT1 may be the key targets for the treatment of allergic rhinitis. Through GO enrichment analysis, it was found that the gene targets of Cangerzi Powder in treatment of allergic rhinitis were involved in 622 biological processes, 62 cellular components, and 152 molecular functions. KEGG analysis obtained 162 pathways, mainly related to immune response, cell regulation and receptors, and other related pathways. Molecular docking confirmed that the core targets STAT3 and MAPK3 could spontaneously bind to key components such as genkwanin and mandenol. Conclusion Cangerzi Powder mainly combines genkwanin and mandenol with STAT3 and MAPK3 to participate in the regulation of immune and inflammation-related signaling pathways and biological cell processes, and finally plays a role in the treatment of allergic rhinitis.
