Investigation on the mechanism of Salviae Miltiorrhizae-Cortex Moutan against cerebral ischemic injury based on network pharmacology

This study aims to explore the effective material,potential targets and molecular mechanisms of Salviae Miltiorrhizae-Cortex Moutan(SM-CM)in treatment of stroke by network pharmacology and molecular docking.Firstly,the active components and their action targets of SM-CM were screened from Traditional Chinese Medicine Systems Pharmacology Database(TCMSP),and the targets for stroke were searched in the CTD,TTD and GeneCards databases.The common targets between the drug and disease were taken as the targets of SM-CM in the treatment of stroke.Then,the interaction relationship of common targets were obtained through the STRING database,and the protein-protein interaction(PPI)network and the component-target network were constructed by Cytoscape.The ClusterProfiler package of R language was used for GO functional and KEGG pathway enrichment analysis(P<0.05),and then the software of Cytoscape was used to build the network of component-target-pathway for visualization.Finally,the key targets and corresponding components in the network were verified by molecular docking in Autodock vina.A total of 67 potential targets were obtained in the treatment of stroke.GO analysis showed that it was mainly involved in response to lipopolysaccharide,response to molecule of bacterial origin,response to oxidative stress and others.KEGG pathway enrichment analysis obtained 149 signaling pathways,mainly involving in AGE-RAGE signaling pathway in diabetic complications,IL-17 signaling pathways,TNF signaling pathways.In addition,the combined activity of the key components with their potential targets were all excellent,and comparing with the results of potential targets with their original ligands.In conclusion,we have confirmed the pharmacodynamic material basis and possible mechanisms of SM-CM in the treatment of stroke by network pharmacology,which will provide scientific basis for further screening its pharmacodynamic components and expanding the scope of clinical use.
