[Abstract]
Objective To study the anticancer mechanism of Ferula sinkiangensisk based on network pharmacology and molecular docking. Methods The chemical substances, target information and component-target correspondence network of F. sinkiangensisk were screened through the SymMap and SwissTargetPrediction database. Genecards database to enter the "cancer" keyword was used to search for disease targets and further screened. Venn diagrams was used to obtain drug-disease intersection targets, and the STRING platform was use to obtain protein-protein interaction (PPI) networks. Gene ontology (GO) enrichment analysis and Kyoto encyclopedia of genes and genomes (KEGG) enrichment pathway analysis were performed on drug-disease intersection targets using DAVID database. Cytoscape 3.9.0 software was used to draw the "active ingredient-target-pathway" network map. Finally, AutoDock software was used to carry out molecular docking experiments on the selected key targets to verify the binding activity. Results 34 chemical constituents and 537 corresponding targets were obtained from F. sinkiangensisk, 1 155 cancer targets and 134 drug-disease intersection targets were screened. GO functional enrichment analysis obtained a total of 331 items (P<0.05) , including 249 biological processes (BP), 31 cellular components (CC) and 51 molecular functions (MF), and 133 KEGG pathways were obtained. The active ingredient-target-pathway network was established. Molecular docking experiments showed that the active substances ferulic acid, farnesfeinol A, farnesfeinol C, limonene and β-pinene had sound binding ability with key targets CCND1, JUN, CXCL8 and PIK3CA. Conclusion Ferulic acid, farnesiferol A, farnesiferol C, limonene, beta-pinene and other chemicals in F. sinkiangensisk, through targets such as CCND1, JUN, CXCL8 and PIK3CA, regulate the expression of PDL-1 and PD-1 immune checkpoint pathway, IL-17 signal pathway, estrogen signal pathway and PI3K-Akt signal pathway to play an anticancer role.
