Four novel geminally dialkylated, non-aromatic acetophenone derivatives ass="boldFont">1-ass="boldFont">4 were isolated from Melicope coodeana. The compounds, related to hop bitter acids, were named Coodeanones A-C, where Coodeanone B was found in both E and Z configuration of the 6鈥测€粹€?鈥测€?double bond. Antibacterial, antifungal and antimalarial activities of the acetophenone derivaties were investigated, and Coodeanone C (ass="boldFont">4) was found to have activity toward Plasmodium falciparum (malaria) (IC50 = 42.8 渭M).
