title: Study on the structure-function relationship of 20(S)-panaxadiol and its epimeric derivatives in myocardial injury induced by isoproterenol.
abstract: This study was aimed to investigate structure-function relationship of 20(S)-panaxadiol (PD) and its epimeric derivatives ((20S, 24S)-epoxy-dammarane-3β, 12β, 25-triol, PDD1 and (20S, 24R)-epoxy-dammarane-3β, 12β, 25-triol, PDD2) in myocardial ischemia injury in rats. It was shown that PD and PDD2 resulted in a reduction in creatine kinase activity. PD and PDD2 inhibited the elevation of malondialdehyde content, the reduction of superoxide dismutase and glutathione peroxidase activities. The pathohistological changes were ameliorated by PD and PDD2. The configuration of C-24 of funan ring was linked to the pharmacological action of 20(S)-panaxadiol and its epimeric derivatives.
