The new structures of 1-7 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 thngi. 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 23.8/23.8μmoloL^-1, respectively.展开更多
