Two new amide alkaloids, clauemaramide A (1) and clauemaramide B (2), and three known analogs were isolated from the stems of Clausena emarginata. Their structures were determined on the basis of spectroscopic analyses. The absolute configurations of 1 and 2 were confirmed by CD spectroscopy. Compound 3 showed moderate inhibitory effects on LPS-induced NO production (IC50 value = 4.9 mu M).
