Abstract

Twelve new A,D-seco-limonoids, clauemargines A-L (1-12), and three known analogues were isolated from the stems of Clausena emarginata. The absolute configurations of 1 and 5 were confirmed by X-ray crystallography and ECD spectroscopy, respectively. Compounds 1, 2, 8-10, and 13 showed moderate inhibitory effects on LPS-induced NO production (IC50 values<10 μM).
