Mechanism of Ginseng-Rhodiola rosea in treatment of myocardial ischemia-reperfusion injury based on network pharmacology and molecular docking / 中国药理学通报

ABSTRACT

Aim To investigate the sites and mechanisms of action of Ginseng-Rhodiola rosea in the treat ment of myocardial ischemia-reperfusion injury ( MI-RI) via using network pharmacology approach, molecu¬lar docking techniques and experimental studies. Methods The active ingredients and targets of Gin¬seng-Rhodiola rosea were screened through the TCMSP database and literature supplementation, and the GEN-EC ARDS ,DISGENET and DRUGBANK databases were searched to obtain the targets of MIRI. Functional pro¬tein interaction networks (PPIs) and the STRING database were used to screen out core targets. The DAVID database was also selected for gene ontology functional analysis ( GO) and KEGG signaling pathway enrich¬ment analysis. Lastly, the preliminary validation was performed with the help of molecular docking techniques and experimental studies. Results Forty-three active ingredients and 348 potential targets of Ginseng-Rhodiola were obtained, and targets such as IL-6 , TNF-α and VEGFA were found to be closely related to MIRI, mainly involving TNF, PDK-Akt, HIF-1 and other signaling pathways.The molecular docking results showed that soysterol, ginsenoside rh2 and rhodioloside had good binding effects and high matching with IL-6, TNF-α,Caspase-3,VEGFA,MAPK1 and other targets, among which the best binding was between Caspase-3 and ginsenoside rh2. The results of the experimental study further showed that Ginseng-Rhodiola rosea could improve myocardial tissue necrosis after myocardial ischemia-reperfusion , reduce myocardial cell edema and vascular congestion, and decrease the expression levels of TNF-α and IL-6 in MIRI rats. Conclusions Ginseng-Rhodiola may modulate multiple targets such as IL-6,TNF-α, Caspase-3, VEGFA and MAPK1 through dousterol, ginsenoside rh2 and rhodiol glycosides to inhibit inflammatory response and oxidative stress, reduce cardiomyocyte damage and exert therapeutic effects on MIRI.
