were isolated and identified from the culture extract of
Aspergillus nidulans
SD-531
a fungus obtained from the deep-sea sediment of cold spring in the South China Sea. Their structures were determined based on detailed interpretation of nuclear magnetic resonance (NMR) spectroscopic and mass spectrometry data analysis. All the isolated compounds were evaluated for antimicrobial activities against human and aquatic bacteria as well as plant pathogenic fungi. Compounds
