A new asymmetric diamide from the seed cake of Jatropha curcas L.

A new asymmetric diamide (E)-N-(3-acetamidopropyl)-cinnamamide named curcamide (1) has been isolated from the ethanol extract of the seed cake of Jatropha curcas L. along with 7 known compounds identified as isoamericanin (2), isoprincepin (3), caffeoylaldehyde (4), isoferulaldehyde (5), glycerol monooleate (6), syringaldehyde (7), and ß-ethyl-d-glucopyranoside (8). The synthesis and antibacterial activity of the new compound have been also studied.
