Integrated network pharmacology and metabolomics to explore the mechanisms of Shenzao dripping pill against chronic myocardial ischemia

Background:Shenzao dripping pill(SZDP)is empirically prescribed for treating cardiac diseases.Nevertheless,there is a lack of comprehensive knowledge regarding the underlying mechanisms contributing to its therapeutic effects.The objective of this study is to investigate the underlying mechanism of SZDP against chronic myocardial ischemia(CMI)in a rat model.Methods:In this study,we utilized electrocardiographic and echocardiographic detection along with pathological tissue analysis to evaluate the efficacy of SZDP.The integration of network pharmacology and metabolomics was conducted to investigate the mechanisms.Molecular docking and molecular dynamics simulations were used to validate the binding energy between the compounds of SZDP and the associated targets.Results:The results showed that SZDP was able to improve T wave voltage,reverse CMI abnormalities in ejection fraction and fractional shortening,and restore histopathological heart damage.Metabolomics results indicated that disturbances of metabolic profile in CMI rats were partly corrected after SZDP administration,mainly affecting purine metabolism.13-Docosenamide may be the potential metabolic biomarker of the therapeutic application of SZDP for CMI.Integrating network pharmacology and metabolomics,thiopurine S-methyltransferase(TPMT),xanthine dehydrogenase/oxidase(XDH),bifunctional purine biosynthesis protein ATIC(ATIC),and cytochrome p4501A1(CYP1A1)were identified as possible targets of SZDP to exert therapeutic effects by enhancing the metabolic levels of L-Tryptophan,Deoxyribose 1-phosphate and Phosphoribosyl formamidocarboxamide.Conclusion:SZDP has a therapeutic effect on CMI by regulating metabolite levels,acting on the targets of TMPT,XDH,ATIC,and CYP1A1,and reducing cardiomyocyte injury and myocardial fibrosis.

Objective:To explore the potential mechanism of Wumei Wan(WMW)in treating diabetes enteropathy(DE)basing on network pharmacology.Methods:The effective compound of WMW were collected by TCMSP,the potential target of WMW was obtained by means of PubChem and Swiss target prediction online tools,and the disease target of DE was obtained by Genecards,TTD and DisGeNET databases,Cytoscape 3.7.2 software was used to construct active ingredients of WMW-potential target-DE network,protein interaction network(PPI)was constructed by STRING database.In order to understanding the mechanism of WMW treating in DE,Omicshare platform was used for GO analysis and KEGG pathway enrichment analysis.The analysis results were verified through docking by Discovery Studio 2016.Results:Total of 128 active components and 139 targets of WMW were screened out from the ten drugs.A total of 714 disease targets were screened out from the disease databases.24 common targets were identified from both WMW and DE.AKT1,MMP9,SRC,PTGS2,PPARG,NOS2,etc.are potential major targets of WMW in the treatment of DE.61 entries(p<0.05)were enriched in GO biological process function related to fatty acid anabolism and ligand receptor binding,as unsaturated fatty acid metabolic process,icosanoid metabolic process,enzyme linked receptor protein signaling pathway,protein amino acid phosphorylation,cellular response to insulin stimulus.A total of 72 signaling pathways were obtained through KEGG pathway analysis(p<0.05).The signaling pathways closely related to DE are including relaxin signaling pathway,EGFR tyrosine kinase inhibitor resistance,CLRs signaling pathway,and VEGF signaling pathway.Conclusion:This study preliminarily revealed the material basis and mechanism of WMW in the treatment of DE from the synergistic aspects of intestinal immune balance,gastrointestinal wall structure reconstruction,intestinal microvascular disorder and neuronal activity.
