Six new diketopiperazines, (±)-7,8-epoxy-brevianamide Q ((±)- 1 ), (±)-8-hydroxy-brevianamide R ((±)- 2 ), and (±)-8-epihydroxy-brevianamide R ((±)- 3 ), together with four known compounds, (±)-brevianamide R ((±)- 4 ), versicolorin B ( 5 ) and averufin ( 6 ), were isolated from a marine-derived fungus strain Aspergillus versicolor MF180151, which was recovered from a sediment sample collected from the Bohai Sea, China. The chemical structures were established by 1D- and 2D-NMR spectra and HR-ESI-MS. 1 is the first sample of brevianamides with an epoxy moiety. Their bioactivities were evaluated against Candida albican s, Bacillus subtilis , Staphylococcus aureus , methicillin-resistant S. aureus , Pseudomonas aeruginosa , and Bacillus Calmette-Guérin. Compounds 1 - 4 showed no activities against the pathogens, and compounds 5 and 6 showed moderate activities against S. aureus and methicillin-resistant S. aureus .
