[Abstract]
Objective To explore the potential mechanism of Yangxue Qingnao Pills in treatment of migraine based on network pharmacology and molecular docking and to conduct its experimental verification. Methods TCMSP and Swiss Target Prediction databases were used to screen the active components and targets of Yangxue Qingnao Pills. Genes related to the occurrence and development of migraine were searched through databases of NCBI GENE, OMIM, CTD, and DisGeNET. The potential targets of treatment were obtained by taking the intersection of the two above. STRING database was used for establishing protein-protein interaction (PPI) networks and key targets were selected by Cytoscape 3.6.0. GO and KEGG pathways involved in the targets were analyzed by DAVID database. "Yangxue Qingnao Pills-herbs-active components-migraine-targets-pathways" network was constructed and key components were screened by Cytoscape 3.6.0, AutoDock software was used to dock the molecules of the key components with the key targets. The migraine rat model induced by nitroglycerin was used to verify key nodes in the results of network pharmacology. Results 140 active components and 279 targets of Yangxue Qingnao Pills were screened. 53 targets were identified for the intersection between Yangxue Qingnao Pills and migraine. The key targets of Yangxue Qingnao Pills in treatment of migraine were IL-6, SLC6A4, TNF, VEGFA, NOS3, etc. The key components were isocorypalmine, quercetin, (S)-scoulerine, bulbocapnine, kaempferol, etc. Molecular docking showed a good binding ability of key components and key target. The enrichment analysis of KEGG pathway showed that Yangxue Qingnao Pills treatment for migraine involved multiple pathways, including neuroactive ligand-receptor interaction, serotonergic synapse, calcium signaling pathway, cAMP signaling pathway, TNF signaling pathway, etc. The results of animal experiments showed that Yangxue Qingnao Pills could inhibit NO, IL-6, TNF-α, VEGF, SLC6A4, and CGRP in serum or brain tissue of migraine rats and increase of 5-HT and 5-HT1B level in brain tissue, significantly improve the symptoms of migraine rats. Conclusion This study reveals the potential active components, key targets and related pathways of Yangxue Qingnao Pills in treatment of migraine, the mechanism maybe related to increase of the level of 5-HT and the 5-HT1B protein expression, inhibition of SLC6A4 and CGRP expression, which provides a basis for further experiments.
