One new xanthenone from the marine-derived fungus Aspergillus versicolor MF160003

AbstractA new xanthenone derivative, 3-hydroxy pinselin (1), together with five known analogues (2–6) were isolated from the marine-derived fungus Aspergillus versicolor MF160003. Their structures were identified by extensive 1D- and 2D-NMR, and high-resolution mass spectrometry data. Compounds 5 and 6 showed moderate bioactivities against BCG with MIC values of 40 and 20 μg/mL, respectively.
