Five new perylenequinone derivatives, altertoxins VIII-XII (-), as well as one known compound cladosporol I (), were isolated from the fermentation broth of the marine-derived fungus sp. KFD33 from a blood cockle from Haikou Bay, China. Their structures were determined based on spectroscopic methods and ECD spectra analysis along with quantum ECD calculations. Compounds - exhibited quorum sensing inhibitory activities against CV026 with MIC values of 30, 30, 20, 30, 20 and 30 μg/well, respectively.
从中国海口湾血蛤中分离到一株海洋来源真菌 sp. KFD33 的发酵液中，分离得到五个新的苝醌衍生物（ altertoxins VIII-XII (-)）和一个已知化合物 cladosporol I (())。基于光谱方法和 ECD 光谱分析以及量子 ECD 计算确定了它们的结构。化合物 - 对 CV026 表现出群体感应抑制活性，MIC 值分别为 30、30、20、30、20 和 30 μg/孔。
