Oximoaspergillimide, a Fungal Derivative from a Marine Isolate ofAspergillussp.

Abstract A new alkaloid, oximoaspergillimide ( 1 ), and the known neohydroxyaspergillic ( 2 ) and neoaspergillic ( 3 ) acids, have been isolated from the extract of a cultured marine‐derived fungus (strain CF07002) identified as a member of the genus Aspergillus . The structure of 1 was determined by interpretation of NMR spectroscopic data, and confirmed by synthesis. The antimicrobial and cytotoxic activities of compounds 1 – 3 were evaluated.
