Chemical constituents of Arisaema franchetianum tubers.[Reference: WebLink]

METHODS AND RESULTS:
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). The inhibitory activities of compound 1 and its N-methyl derivative (1a) against porcine respiratory and reproductive syndrome virus (PRRSV), human leukemic K562 cells, and human breast cancer MCF-7 cells were evaluated.
CONCLUSIONS:
Compounds 1 [50% inhibited concentration (IC50) = 12.5 ± 0.6 μM] and 1a (IC50 = 15.7 ± 0.9 μM) were cytotoxic against K562 cells. Compound 1a also had a weak effect on PRRSV with an IC50 value of 31.9 ± 6.0 μM [selectivity index (SI) = 18.7].
