Triterpenoids from Acanthopanax koreanum root and their inhibitory activities on NFAT transcription.
Two triterpenoids (1,4) and two triterpenoid glycosides (2,3) were isolated from the root of Acanthopanax koreanum (Araliaceae). Their structures were identified as impressic acid (1), acankoreoside A (2), 3-epi-betulinic acid 28-O-[alpha-L-rhamnopyranosyl(1 --> 4)-beta-D-glucopyranosyl(1 --> 6)]-beta-D-glucopyranosyl] ester (3), and ursolic acid (4) by physicochemical and spectroscopic methods. Of these compounds, impressic acid (1) exhibited a potent inhibitory activity against NFAT transcription factor (IC50: 12.65 microM).
