Abstract: This study was aimed to explore the antibacterial mechanism of the main components of Chinese traditional medicine Coptidis Rhizoma based on network pharmacology.The effective components and target targets of Coptidis Rhizoma were screened from the TCMSP database,and the corresponding target genes were transformed using the Uniprot database.The active components and target genes were imported into the Cytoscape 3.6.1 software to construct an active component-target network diagram.Combined with the GeneCards database to search the antibacterial related targets of Coptidis Rhizoma,the core target genes were uploaded to the STRING platform to build a protein interaction network.Finally,the DAVID database was used to analyze key targets by GO biological processes and KEGG pathway enrichment.The results of network pharmacology showed that 9 effective components of Coptidis Rhizoma acted on 105 antibacterial targets and participated in 22 biological processes (18 biological processes,3 molecular functions,1 cell composition) and 19 related signal pathways.Among them,the main active ingredients of Coptidis Rhizoma were quercetin,(R)-Canadine,berlambine,berberine and palmatine,etc.Antibacterial targets were IL2,VCAM1,STAT1,NOS2,TGFB1,CASP9,MMP1,NFKBIA and CXCL10,etc.The involved biological processes mainly included inflammatory response,positive regulation of RNA polymerase Ⅱ promoter transcription,response to lipopolysaccharide,negative regulation of apoptotic process,cell adhesion,etc.Mainly act on Toll-like receptors signal pathway,TNF signal pathway,NF-kappa B signaling pathway,etc.Coptidis Rhizoma might through its active ingredients such as quercetin,berberine,palmatine act on other key targets such as IL2,VCAM1 and STAT1 to participate in the Toll-like receptor signaling pathway and TNF signaling pathway to exert antibacterial effect.It fully reflected the antibacterial action mechanism of Coptidis Rhizoma with multiple components,multiple targets and multiple pathways,and provided a theoretical reference for further clarifying the antibacterial mechanism of Coptidis Rhizoma.
