Biological Activity

Description (20S)-Protopanaxatriol (g-PPT, 20(S)-APPT), a neuroprotective metabolite of ginsenoside, protopanaxatriol (g-PPT), is a functional ligand for both GR and ERbeta and could modulate endothelial cell functions through the glucocorticoid receptor (GR) and estrogen receptor (ER).
In vitro Protopanaxtriol (Ppt) is a neuroprotective ginseng extract. Ppt exerts its antioxidative activity via several mechanisms, such as direct scavenging of free radicals and restoration of succinate dehydrogenase activity. These mechanisms may contribute to its potent antioxidative and putative neuroprotective activities[1]. Ppt exhibited strong noncompetitive inhibition towards UGT1A1 and competitive inhibition towards UGT2B7. The inhibition kinetic parameters (Ki) were calculated to be 8.8 and 2.2 μM for UGT1A1 and UGT2B7, respectively[2]. PPT could repress the viability and invasiveness, and promote the apoptosis in A549 and SK-MES-1 cells.
In vivo Protopanaxtriol (Ppt) is shown to reduce learning and memory impairment associated with Alzheimer's diseases and protect against 3-NP-induced oxidative stressin the rat model of Huntington's disease, which is associated with its anti-oxidant activity. Ppt prevents short- and long-term memory impairments induced by chronic sleep deprivation probably through antagonizing oxidative stress in the cortex and hippocampus[1].

Protocol (from reference)

Cell Assay:[3]
  • Cell lines

    A549 cells or SK-MES-1 cells

  • Concentrations

    0, 0.4, 4 or 40 uM

  • Incubation Time

    48 h

  • Method

    A549 cells or SK-MES-1 cells are seeded in 96-well plates (3×103 cells/well), and then treated with different concentration of PPD, PPT, G-Rg3 or G-Rh2 (0, 0.4, 4 or 40 μM) for 48 h, with cisplatin (2 ug/ml) as a positive control and 0.1% DMSO as a blank control. Then these cells are collected and detected the viability by the cell-counting Kit-8 (CCK-8) assay.

Animal Study:[1]
  • Animal Models

    ICR male mice

  • Dosages

    20μmol/kg, 40μmol/kg

  • Administration

    i.p.
