Xylomexicanins A and B, New Δ14,15-Mexicanolides from Seeds of the Chinese Mangrove Xylocarpus granatum

Abstract

Two new mexicanolide-type limonoids, named xylomexicanin A (1) and xylomexicanin B (2), were isolated from seeds of the Chinese mangrove Xylocarpus granatum. Their structures were elucidated on the basis of spectroscopic methods. Compound 1 exhibited antipro-liferative activity against human breast carcinoma cells (KT), while 2 did not show inhibitory effects on eleven human tumour cell lines tested. © 2009, Verlag der Zeitschrift für Naturforschung.
