Recent studies focusing on identifying the biological agents of Catharsius molossus have led to the identification of three new N-acetyldopamine dimers molossusamide A–C (1-3) and two known compounds 4 and 5. The structures of the new compounds were identified by comprehensive spectroscopic evidences. Compound 4 was found to have inhibitory effects towards COX-1 and COX-2.
