Lignans from Acanthopanax chiisanensis having an inhibitory activity on prostaglandin E2 production.

The chloroform and the ethyl acetate fractions from the roots of Acanthopanax chiisanensis exhibited the significant inhibition of TPA-induced prostaglandin E(2) (PGE(2)) production in rat peritoneal macrophages. Five lignans were isolated from the chloroform fraction and their structures were elucidated as l-sesamin, helioxanthin, savinin, taiwanin C, and 3-(3,4-dimethoxybenzyl)-2-(3,4-methylenedioxybenzyl)butyrolactone. Among the lignans tested, taiwanin C showed the most potent inhibitory activity (IC(50) = 0.12 microM) on PGE(2) production with the relative order of potency, taiwanin C >> 3-(3,4-dimethoxybenzyl)-2-(3,4-methylenedioxybenzyl)butyrolactone > savinin = helioxanthin. l-Sesamin showed no inhibitory activity at 30 microM.[1]
