| Description | Isoformononetin shows fungitoxic activity against Cladosporium sphaerospermum; it also has immunomodulatory activity, it inhibits the differentiation of Th17 cells and B-cell lymphopoesis to promote osteogenesis in estrogen-deficient bone loss conditions. Isoformononetin reverses bone loss in osteopenic rats and exerts bone anabolic action by preventing osteoblast apoptosis. |
| In vitro | A novel pyrrolidine alkaloid, (2R*,3S*,5S*)-N,2-dimethyl-3-hydroxy-5-(10-phenyldecyl)pyrrolidine (1), and 17 known compounds were isolated from Arisaema franchetianum Engl. (Araceae) tubers. The 17 compounds were bergenin (2), emodin (3), caffeic acid (4), nobiletin (5), 3-O-β-d-galactopyranosyl-hederagenin 28-O-β-d-xylopyranosyl(1 ?? 6)-β-d-galactopyranosyl ester (6), coniferin (7), qingyangshengenin (8), methylconiferin (9), syringaresinol 4'-O-β-d-glucopyranoside (10), gagaminine (11), perlolyrine (12), (S)-1-(1'-hydroxyethyl)-β-carboline (13), 1-(β-carboline-1-yl)-3,4,5-trihydroxy-1-pentanone (14), 1-methoxycarbonyl-β-carboline (15), indolo[2,3-α±]carbazole (16), 4-hydroxycinnamic acid methyl ester (17), and methyl 4-[2-hydroxy-2-(4-hydroxy-3-methoxyphenyl)-1-(hydroxymethyl)ethyl] ferulate (18)[1] |
