Mechanism of action of active components of Prunus armeniaca L.var.ansu Maxim.mature seed for vasospasm based on network pharmacology and in vitro experiments
Objective To explore the potential mechanism of the active components of Prunus armeniaca L.var.ansu Maxim.mature seed for vasospasm by integrating network pharmacology and in vitro cell experiments.Methods We searched TCMSP,Genecards,SwissTargetPrediction database,Drugbank database,and other related literatures to obtain active components in Prunus armeniaca L.var.ansu Maxim.mature seed,action targets Rhizoma,and corresponding disease targets.The intersection of action and disease targets was taken as the potential targets.A protein-protein interaction network(PPI)for potential targets was established based on String platform.R language software package was used to analyze the function of Gene Ontology(GO)and the enrichment of Kyoto Encyclopedia of Genes and Genomes(KEGG),and then Cytoscape software was used to analyze its network topology and further screen core targets.Molecular docking was used to verify the predicted results.Subsequently,the effect of active components in Prunus armeniaca L.var.ansu Maxim.mature seed on the proliferation of vascular smooth muscle cells(VSMCs)induced by angiotensin Ⅱ(Ang Ⅱ)was detected by MTT.Results Totally 17 main potential active components of Prunus armeniaca L.var.ansu Maxim.mature seed in the treatment of vasospasm and 68 drug-disease targets were found.The main signaling pathways include calcium signaling pathway,neuroactive ligand-receptor interaction,sphingolipid signaling pathway,vascular smooth muscle contraction,EGFR tyrosine kinase inhibitor resistance,relaxin signaling pathway,etc.The stable conformations were formed between the core targets and the active components,amygdalin and estrone.The in vitro results showed that amygdalin inhibited Ang Ⅱ-induced proliferation and phenotype transformation of VSMCs through inactivating the MAPKs signaling pathways.Conclusion Various active components in Prunus armeniaca L.var.ansu Maxim.mature seed may play a role in vasospasm by acting on targets such as matrix metallopeptidase 9(MMP9),estrone,etc.The study helps reveal the mechanism of active components of Prunus armeniaca L.var.ansu Maxim.mature seed in the treatment of vasospasm.
