Abstract | BACKGROUND: METHODS: Rats were divided into 7 groups and dosed consecutively for 7 days with mono and combined- therapy administrations. Serum samples were analyzed by proton nuclear magnetic resonance (1H NMR) spectroscopy. Partial least squares discriminate analysis (PLS-DA) was employed to distinguish the metabolic profile of rats in different groups and identify potential biomarkers. RESULTS: Score plots of PLS-DA exhibited that combined- therapy groups were significantly different from AMI group, whereas no differences were observed for mono- therapy groups. We found that AMI caused comprehensive metabolic changes involving stimulation of glycolysis, suppression of fatty acid oxidation, together with disturbed metabolism of arachidonic acid, linoleate, leukotriene, glycerophospholipid, phosphatidylinositol phosphate, and some amino acids. β-hydroxybutyrate, cholines and glucose were regulated by mono- therapy of schizandrin and ginsenosides respectively. Besides these metabolites, combined- therapy ameliorated more of the AMI-induced metabolic changes including glycerol, and O-acetyl glycoprotein. A remarkable reduction of lactate suggested the therapeutic effect of combined- therapy through improving myocardial energy metabolism. CONCLUSIONS: This study provided novel metabonomic insights on the mechanism of synergistic cardioprotection of combined- therapy with ginsenosides, schizandrin, and ophiopogonin D, and demonstrated the potential of discovering new drugs by combining bioactive components from traditional Chinese formula.
