Objective To investigate the multi-component, multi-target, and multi-pathway mechanism of Scolopendra subspinipes mutilans in treating glioblastoma by using network pharmacology and molecular docking technology. Methods The related components of Scolopendra subspinipes mutilans were obtained through BATMAN-TCM, HERB databases and literature search, and the targets were predicted by SwissTargetPrediction. The related targets of glioblastoma were obtained from GeneCards, OMIM, and TTD databases. The potential targets of Scolopendra subspinipes mutilans in treating glioblastoma were obtained by summarizing and removing duplicates of the two. The intersection genes were imported into STRING for PPI analysis to generate a PPI network diagram, and network topology analysis was performed using Cytoscape. The core targets and core drug components were determined using the CytoNCA plugin, and a “drug – component-target” diagram was made. GO biological function and KEGG pathway enrichment analysis were conducted in the DAVID database, and a “drug component-disease target-pathway” diagram was drawn using Cytoscape. Molecular docking verification was then performed using AutoDock Vina. Results There were 46 effective components of centipedes and 708 targets were screened out. There were 2 151 targets of glioblastoma, and 180 intersection genes were obtained. GO enrichment analysis yielded 997 items, and 153 KEGG enrichment analysis pathways were obtained, mainly involving cancer pathways, apoptosis, PI3K/Akt signaling pathway, TNF signaling pathway, and ErbB signaling pathway, etc. Through CytoNCA analysis, Akt1, STAT3, EGFR, JUN, Src were screened out as possible core targets, and cyclo-(L-Phe-L-Tyr), cyclo-(L-Phe-L-Pro), cyclo-(L-Val-L-Pro), N-(2-phenylethyl) acetamide, cyclo-(L-Leu-L-Pro) were screened out as possible core components of Scolopendra subspinipes mutilans in treating glioblastoma. Molecular docking verification showed that the core components and core targets could bind well. Conclusion Scolopendra subspinipes mutilans in treating glioblastoma involves cyclo-(L-Phe-L-Tyr), cyclo-(L-Phe-L-Pro), cyclo-(L-Val-L-Pro), N-(2-phenylethyl) acetamide, cyclo-(L-Leu-L-Pro), Akt1, STAT3, EGFR, JUN, Src, and PI3K/Akt, TNF, and ErbB signaling pathways through multi-component, multi-target, and multi-pathway approaches.
