Phytochemical investigation of the stem bark of
Xylopia pierrei Hance led to the isolation of one triterpene,
polycarpol (1), three heptenes, (7R)-acetylmelodorinol (2),
(7R)-melodorinol (3), and melodienone (8), and four flavonoids,
pinocembrin (4), isochamanetin (5), chrysin (6),
and dichamanetin (7). All compounds were isolated for the
first time from this plant species. The structures of the
isolated compounds were characterized by spectroscopic
techniques and by comparison of the spectroscopic data
with the literature values and the stereochemistry at the
asymmetric carbon was determined by the modified
Mosher s method. Among them, compound 2 displayed
potent cytotoxic activity against human small cell lung
cancer (NCI-H187) cells with an IC50 value of 6.66 (mu)M and
it was 2.3-fold higher than that of the reference anticancer
drug, ellipticine. In addition, compound 2 was also evaluated
against the non-cancerous Vero cells and showed high
selectivity index of 8.89, which is 59-fold greater than that
of ellipticine. The findings suggest that compound 2 should
be further developed as a potential lead molecule for
anticancer drug development.
