Objective To explore the potential molecular mechanism of Kang'ai injection against colorectal cancer via regulating intestinal microbial metabolites based on network pharmacology and molecular docking.Methods The active components and targets of Kang'ai injection were obtained from TCMSP and BATMAN-TCM databases.GutMGene database was used to collect the targets related to intestinal microbial metabolites.The targets of colorectal cancer were retrieved based on GeneCards,OMIM,DisGeNET and TTD databases.The intersection of the three types of targets was used to screen potential targets.Cytoscape was used to construct the active component-target network,and the PPI protein interaction network was constructed based on the STRING database and topological analysis was performed.The GO function and KEGG pathway enrichment analysis of the core targets were completed by R software,and the binding stability of the main active components to the key targets was verified by molecular docking.Results Huagiannin,isoflavanone,and kaempferol were identified as the main active ingredients,while IL6,TP53,and AKT1 were determined as the key therapeutic targets.GO enrichment analysis indicated that the biological processes were mainly involved in cell proliferation,apoptosis,and inflammatory response.KEGG pathway enrichment analysis revealed that the core targets were primarily enriched in signaling pathways including AGE-RAGE and IL-17.Molecular docking demonstrated favorable binding affinity between the main active ingredients and the key targets.Conclusion Kang'ai injection exhibits synergistic anti-tumor properties characterized by multi-component,multi-target,and multi-pathway actions.It may exert potential anti-colorectal cancer effects by modulating inflammatory,immune,and metabolism-related signaling pathways,thereby improving the gut microbial microenvironment.However,as this study is solely based on network pharmacology predictions without in vivo or in vitro experimental validation,certain limitations exist.Further experimental studies are warranted to substantiate the underlying mechanisms and provide theoretical support for its adjuvant therapy in colorectal cancer.
