Effect of triterpene esters and the corresponding alcohols ((a) arnidiol-3-myristate, arnidiol; (b) calenduladiol-3-myristate, calenduladiol; (c) faradiol-3-myristate, faradiol) on the NF-κB driven transcription. AGS cells were transiently transfected with NF-κB-luc plasmid and treated with TNF-α in the presence of triterpene esters or alcohols (1–50 μM) for 24 h. The table reports the IC50 values and relative percentages (w/w) of triterpene esters in lipophilic extract.
