[Abstract]
Objective To rapidly screen and identify the potential anti-neuropathic pain active components in Salvia miltiorrhiza standard decoction by live cell extraction and liquid chromatography-mass spectrometry, and analyze the mechanism of action by network pharmacology. Methods Using mouse dorsal root neuron cells co-incubated with Salvia miltiorrhiza PBS solution, the adsorption components were identified by UPLC-Q-Orbitrap HRMS, and the components were analyzed based on network pharmacology and their mechanism of action. TCMSP database and Swiss database were used to search for the target of component action. The disease target was retrieved from Genecards database and OMIM database with the keyword "neuropathic pain". The common target was obtained by interscreening the component target and neuropathic pain target. The common targets were imported into the STRING database for retrieval to obtain protein interaction (PPI) network, and then imported into Cytoscape 3.7.2 for drawing. The top 10 targets were selected as key targets according to the degree value. Common targets were analyzed using the ClusterProfiler package for gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment. Results A total of 11 potential active ingredients were identified, namely vanillic acid, danshensu, caffeic acid, protocatechuic acid, protocatechuic aldehyde, ferulic acid, rosmarinic acid, shikonic acid, salvianolic acid B, isotope salvianolic acid B and salvianolic acid E, the network pharmacology analysis showed that there were 174 targets, and 67 intersected with the target set of neuropathic pain. Protein interaction network analysis showed that STAT3, ALB, JUN, APP, MMP9, CASP3, TLR4, MAPK1, PTGS2, RELA as core targets The network topology analysis of "medicine components-target" showed that there may be synergistic effects of S. miltiorrhiza components. GO enrichment analysis showed that it was related to biological processes such as bicarbonate transport, response to lipopolysaccharide, and response to molecule of bacterial origin, membrane rafts, etc. raft, membrane microdomain, membrane region, secretory granule lumen and other cell composition and carbonate dehydratase activity, hydrolase activity, carbonoxygen lyase activity and other molecular functions. KEGG enrichment shows that it was related to nitrogen metabolism, AGERAGE signaling pathway in diabetic complications, lipid and atherosclerosis HIF-1 signaling pathway and other pathways. Combined with literature analysis, its onset mechanism was related to inflammation and immune response, neuronal recovery and regeneration, metabolic disorder, virus, pain transmitter conduction, neuronal hypersensitivity, pain threshold, etc. Conclusion Eleven antineuropathic pain active ingredients in S. miltiorrhiza standard decoction were screened by live cell solid phase chromatography and high resolution mass spectrometry. Bridging network pharmacology was used to analyze the mechanism of action, which may be related to inflammation and immune response, regulation of metabolic disorders, and inhibition of hypersensitivity.
