Protopanaxatriol is a natural PPARγ antagonist with an IC50 of 11.75 μM (Ki=4.2 μM).
In Vitro:Protopanaxatriol (PPT) does not show an inhibitory effect on other nuclear receptors involved in metabolic disorders, such as PPARα and PPARβ/σ, LXRα and LXRβ. A competitive binding assay using TR-FRET is performed. Protopanaxatriol is able to displace the Rosiglitazone from binding to PPARγ at an IC50 value of 11.75 μM (Ki=4.2 μM). Compared with unlabeled Rosiglitazone (Ki=43 nM), the PPARγ binding affinity of PPT is moderate[1]. To evaluate whether PPD, Protopanaxatriol (PPT), G-Rg3 and G-Rh2 regulate viability of lung cancer cells, the CCK-8 assay is performed to analysis the effect of these four compounds on the viability of A549 or SK-MES-1 cells. For A549 cells, all these compounds (PPD, Protopanaxatriol, G-Rg3 and G-Rh2) can notably inhibit the viability in a dosage-dependent manner (P<0.05, P<0.01 or P<0.001), especially at the concentration of 40 uM[2].
In Vivo:Protopanaxatriol, a novel PPARγ antagonist from Panax ginseng, alleviates steatosis in mice. onsistent with the increase of body temperature, the expression of uncoupling protein (UCP)-1, UCP-2 and UCP-3 genes, involved in energy dissipation and adoptive thermogenesis in brown adipose tissue (BAT), is enhanced in the brown adipose tissue (BAT) of PPT-treated mice. The other adipose tissue involving in the heat production and energy expenditure is beige adipose in WAT. The elevated expression of UCP-1 is a key feature for browning of WAT. Protopanaxatriol treatment increases the expression of UCP-1 in WAT[1].

Simultaneous determination of five active hydrolysis ingredients from Panax quinquefolium L. by HPLC-ELSD.[Pubmed:20737654]
Biomed Chromatogr. 2011 Jun;25(6):646-51.
An effective method for simultaneous determination of five hydrolysis products of 20 (R)-dammarane-3beta,6alpha,12beta,20,25-pentol, 24(R)-ocotillol, 20(R)-Protopanaxatriol, 20(S)-panaxatriol and 20(R)-dammarane-3beta,12beta,20,25-tetrol was developed using high-performance liquid chromatography with evaporative light scattering detection (HPLC-ELSD). The hydrolysis products from Panax quinquefolium L. in the stems and leaves, berries, flower buds and roots components were successfully separated on a Kromasil C(18) column using methanol and water (83:17, v/v) as mobile phase in 18 min. The parameter for the ELSD was set to a probe temperature of 40 degrees C and the nebulizer for nitrogen gas was adjusted to 3 L/min. All calibration curves showed good linear regression (r > 0.9975) within test ranges. The validation of the method included recovery, linearity, accuracy and precision (intra- and inter-day variation). The accuracy and precision were satisfactory, with the overall intra- and inter-day variation being less than 3.11%, and recoveries of this method were greater than 95.0%. This study developed an effective and rapid method for simultaneous determination of multiple hydrolysis components from Panax quinquefolium L.
