摘要
Seven new aromatic polyketides, communols AG (17), were isolated and identified from the fermentation broth of Penicillium commune 518, a marine-derived fungus associated with the Gorgonian, Muricella abnormalis. The new structures of 17 were determined by spectroscopic analysis and X-ray single crystal diffraction. Among them, communol D (4) was the first example of a naturally occurring aromatic polyketide with a sulfoxide group from marine fungi. Compounds 1, 6, and 7 all showed moderate antimicrobial activities against Escherichia coli and Enterobacter aerogenes with MIC values of 4.1/16.4, 6.4/25.8, and 23.8/23.8 mu mol center dot L-1, respectively.
