A ginsenoside metabolite that has been linked to endothelial cell function via the glucocortoid receptor (GR) and the oestrogen receptor (ER).
애플리케이션
20S-Protopanaxatriol (g-PPT), a dammarane-type tetracyclic terpene sapogenin, may be used to study its binding to and modulation of cell function via glucocortoid (GR) and oestrogen (ER) receptors.

A metabolites of ginsenoside, protopanaxatriol (g-PPT), could modulate endothelial cell functions through the glucocorticoid receptor (GR) and oestrogen receptor (ER).
We previously reported that 17β-estradiol (E2) is pronociceptive in a visceral pain model in the rat. Subcutaneously (s.c.) administered E2 reversed the decrease in the colorectal distention (CRD)-evoked visceromotor response produced by ovariectomy (OVx) and CRD-induced nociceptive responses were greater
Estrogens exert many of their behavioral effects by binding to nuclear estrogen receptor (ER) proteins, ERalpha and ERbeta. Recent studies involving ER knockout mice and selective ER agonists suggest that estradiol's anorexigenic effect is mediated via activation of ERalpha. To

Ginseng, a commonly used natural product, has been frequently reported to induce herb-drug interaction with many clinical drugs. The intestinal bacterial metabolites of ginsenosides have been widely regarded as the substance basis for ginseng-drug interactions. To date, little is known

Although the biotransformation of ginsenosides in the gastrointestinal tract has been extensively studied, much less is known about hepatic cytochrome P450 (P450)-catalyzed metabolism. The major aims of this study were to clarify the metabolic pathway and P450 isoforms involved and

Ginsenoside Re (G-Re) improved the memory function of experimental animals in a preclinical study. Several types of saponins including G-Rg1, G-Rg2, G-F1, G-Rh1, and protopanaxatriol (PPT) may be the metabolites of G-Re according to reports from preclinical trials. In order
