Abstract:
Objective:To explore the mechanism of Fuyuan Xingnao Decoction in treatment of cerebral infarction based on network pharmacology and molecular docking.Methods:The active components and action targets of Fuyuan Xingnao Decoction were screened by using Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP),Traditional Chinese Medicine Integrated Database (TCMID),Bioactivity data of small organic molecules (PubChem),Universal Protein (Uniprot) and Swiss Target Prediction database platform. The databases of GeneCards, Online Mendelian Inheritance in Man (OMIM), Therapeutic Target Database (TTD), and Drug Bank and Pharmacogenomics Knowledgebase (PharmGKB) were used to screen targets of cerebral infarction. The drug target genes in Fuyuan Xingnao Decoction were intersected with those of cerebral infarction, the intersecting targets were introduced into Cytoscape 3.8.2 software to construct the component target network, and the PPI protein interaction network was constructed by using STRING analysis platform and Cytoscape 3.8.2 software to screen the core targets. Gene Ontology (GO) function enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) function enrichment analysis were carried out on the common target genes of Fuyuan Xingnao Decoction and cerebral infarction disease to obtain the relevant signal pathways. Finally, AutoDock and Pymol software were used for molecular docking between the predicted target and its corresponding components.Results:After screening, 80 effective components of Fuyuan Xingnao Decoction for treatment of cerebral infarction and 214 common targets of Fuyuan Xingnao Decoction and cerebral infarction were obtained. The core targets such as MAPK1, RELA, TP53, JUN, AKT1 and HSP90AA1 were related to the key targets of cerebral infarction, and they participated in the biological process of regulating the response to drugs, lipopolysaccharide and oxygen level, etc. The cell composition involved membrane raft, membrane micro region and nerve cell body, etc. Molecular functions mainly focused on nuclear receptor activity, ligand activated transcription factor activity, DNA binding transcription factor binding, etc.; it also involved in signal pathway of lipid and atherosclerosis, chemical carcinogen and receptor activation, fluid shear stress and atherosclerosis, etc. Molecular docking showed that good binding activities were seen between Quercetin and HSP90AA1 (-9.4 kJ/mol), between Kaempferol and HSP90AA1 (-9.4 kJ/mol), between Isorhamnetin and HSP90AA1 (-9.1 kJ/mol), and between Quercetin and JUN (-8.6 kJ/mol).Conclusion:Fuyuan Xingnao Decoction can prevent and treat cerebral infarction by regulating vascular endothelial function, promoting blood circulation, repairing and improving neural function, protecting blood-brain barrier, reducing cell apoptosis, and regulating immune and inflammatory response.
