A new diphenolic metabolite isolated from the marine-derived fungus Aspergillus niger 102

A new diphenolic derivative asperdiphenol A (1), along with nine known compounds (2-10), was isolated from the marine-derived fungus Aspergillus niger 102. Their structures were elucidated on the basis of spectroscopic analysis including NMR and MS spectrometry. Compound 1 was suggested to be a chiral mixture by the specific rotation and chiral HPLC. Compound 1 was evaluated for its anti-inflammatory, antibacterial, and cytotoxic activity. [GRAPHICS] .
