Objective To investigate the potential therapeutic targets and mechanisms of solamargine in the treatment of nasopharyngeal carcinoma based on network pharmacology and molecular docking. Methods Potential targets of solamargine were collected from BATMAN, CTD, GeneCards, HERB, SwissTargetPrediction, TCMSP, and PharmMapper databases. NPC-related targets were retrieved from DrugBank, GeneCards, MalaCards, OMIM, and OpenTarget databases. Common targets between solamargine and NPC were identified using R software. A protein-protein interaction (PPI) network was constructed with STRING_v12.0 database and Cytoscape v3.10.0. Gene Ontology (GO) and KEGG pathway enrichment analyses were performed using clusterProfiler packages in Rv4.4.3. Finally, core targets were identified by calculating node scores using the CytoNCA and MCODE plugins, along with the CytoHubba extension, followed by molecular docking validation performed with AutoDockTools_ 1.5.7 software. Results Common targets (121) of solamargine-nasopharyngeal carcinoma were obtained by network pharmacology analysis. There are 29 core targets such as Akt1, ALB, ANXA5, Bcl2, Bcl2L1, CASP3, CASP9, MMP9, STAT3 were identified. GO showed that the most significant BP involved in the potential targets of solamargine were response to lipopolysaccharide and response to molecule of bacterial origin, MF included endopeptidase activity, carboxylic acid binding and protein serine/threonine kinase activity, CC were ficolin-1-rich granule, membrane raft and membrane microdomain. KEGG pathway analysis involved TNF signaling pathway, MAPK signaling pathway, IL-17 signaling pathway and p53 signaling pathway, etc. The molecular docking results demonstrated that solamargine had the ability to bind to the core target. Conclusion Solamargine may participate in the immune regulation, apoptosis and survival of nasopharyngeal carcinoma by binding to multiple targets such as Akt1 and ALB and regulating multiple signaling pathways such as TNF and MAPK, thereby exerting an anti-nasopharyngeal carcinoma effect.
