Effect of 20(S)-protopanaxatriol and its epimeric derivatives on myocardial injury induced by isoproterenol.

Objective: It was reported Panax ginseng had diverse components and multifaceted pharmacological functions. This study aims to investigate the effect of 20(S)-protopanaxatriol (PT, CAS 179799-20-3) and its epimeric derivatives (20S, 24R-epoxy-dammarane-3beta, 6alpha, 12beta, 25-tetraol, PTD1 and 20S, 24S-epoxy-dammarane-3beta, 6alpha, 12beta, 25-tetraol, PTD2) on myocardial injury induced by isoproterenol in rats.

Methods: Male Wistar rats were administered orally 20(S)-protopanaxatriol or its epimeric derivatives for 7 days.

Study on the structure-function relationship of 20(S)-panaxadiol and its epimeric derivatives in myocardial injury induced by isoproterenol.

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.
