Objective To explore the material basis and mechanism of Cordyceps sinensis in treatment of chronic obstructive pulmonary disease based on network pharmacology and molecular docking techniques.Methods TCMSP and other databases were used to screen the active ingredients of Cordyceps sinensis and predict their targets.GeneCards and OMIM databases were used to screen chronic obstructive pulmonary disease targets.After merging and deduplicating,the intersection with the active ingredient targets was taken.PPI network of intersection targets was constructed using String database,and the topology analysis and visualization were performed using Cytoscape 3.8.2 software.The Metascape database was used to perform GO functional enrichment analysis and KEGG pathway enrichment analysis of the core targets.Finally,Molecular docking verification was performed using SwissDock and Pymol software.Results 14 Active components were selected from Cordyceps sinensis,including arachidonic acid,cerevisterol,beta-sitosterol,lysergol,glycitein,cholesteryl palmitate,cholesterol,linoleyl acetate,stigmasterol,peroxyergosterol,campesterol,adenosine,D-mannitol,and ergosterol.There were 91 intersecting targets of Cordyceps sinensis ingredients associated with chronic obstructive pulmonary disease disease,involving TNF,TP53,CASP3,EGFR,MMP9,and SRC.GO and KEGG analysis results showed that the mechanism of Cordyceps sinensis intervention in chronic obstructive pulmonary disease mainly involved pathways in cancer,proteoglycans in cancer,lipid and atherosclerosis,calcium signaling pathway,VEGF signaling pathway,inflammatory mediator regulation of TRP channels.Molecular docking results demonstrated that cerevisterol,the core active components of Cordyceps sinensis,has a highest affinity with MMP9.Conclusion In this study,it was found that Cordyceps sinensis may act on the disease related targets of TNF,TP53,CASP3,EGFR,MMP9,and SRC through its active components,such as arachidonic acid,brewer sterol,β-sitosterol,cholesterol palmitate,linoleate acetate,adenosine and ergosterol.By regulating cancer pathways,cancer-related proteoglycans play a role in the intervention of chronic obstructive pulmonary disease.
