Five lignans, l-sesamin, savinin, helioxanthin, taiwanin C, and cis-dibenzylbutyrolactone, were isolated from the root of Acanthopanax chiisanensis (Araliaceae), a Korean medicinal plant, and their inhibitory effects on the production of prostaglandin (PG) E(2) stimulated by
Anti-estrogenic activity of (-)-sesamin (1), helioxanthin (2), savinin (3), taiwanin C (4), and 3-(3,4-dimethoxybenzyl)-2-(3,4-methylenedioxybenzyl)butyrolactone (5) isolated from the root of Acanthopanax chiisanensis was tested using Ishikawa cells. Among them, compound 3 exhibited anti-estrogenic
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
Effects of compounds isolated from medicinal plants in Korea on prostaglandin E2 (PGE2) production in rat peritoneal macrophages were examined, and mechanism of action of the active constituents was analyzed. The active constituents were as follows; tectorigenin and tectoridin isolated from the
