Carneusones A-F, Benzophenone Derivatives from Sponge-Derived Fungus <i>Aspergillus carneus</i> GXIMD00543

Abstract

Six benzophenone derivatives, carneusones A-F (1–6), along with seven known compounds (7–13) were isolated from a strain of sponge-derived marine fungus Aspergillus carneus GXIMD00543. Their chemical structures were elucidated by detailed spectroscopic data and quantum chemical calculations. Compounds 5, 6, and 8 exhibited moderate anti-inflammatory activity on NO secretion using lipopolysaccharide (LPS)-induced RAW 264.7 cells with EC50 values of 34.6 ± 0.9, 20.2 ± 1.8, and 26.8 ± 1.7 μM, while 11 showed potent effect with an EC50 value of 2.9 ± 0.1 μM.
