Four new sulfur-containing compounds, named clinamides A-C (1
), and 2-cis
-entadamide A (4
), were isolated together with three known compounds from the bioactive ethanol extract of the aerial parts of Clinacanthus nutans
. These secondary metabolites possess sulfur atoms and acrylamide functionalities. The structures of the isolated components were established by interpretation of their spectroscopic data, especially 1D and 2D NMR.
