Ginsenoside 20 ( R ) -Rh1
It is the 20 ( R ) epimer of ginsenoside 20 ( S ) -Rh1
- Yu2005pgd says that gssd. 20 ( R ) Rh1, as well as its 20 ( S ) epimer, increase the binding of NF-κB transcription factor to DNA in mouse splenocyte culture. They also increase the production of T-bet transcription factor and type 1 cytokines controlled by IFN-γ. The highest effect on IFN-γ was at concentrations of 5 and 10 μM (+ 100%), at higher concentrations the effect was again reduced (at 50 μM only + 50%).
