A novel linear polyketide, amphirionin-2 (1), with two unique hexahydrofuro[3,2-b]furan moieties has been isolated from the cultivated algal cells of a benthic dinoflagellate Amphidinium sp. (strain KCA09051). The structure was elucidated on the basis of detailed analyses of 2D NMR data, and the absolute configuration of C-5 was determined by using modified Mosher's method. Amphirionin-2 (1) exhibited potent cytotoxic activity against human colon carcinoma Caco-2 cells and human lung adenocarcinoma A549 cells.
从底栖双鞭毛藻Amphidinium sp.(菌株KCA09051)的培养藻细胞中分离出一种新型线性聚酮化合物——海葵素-2(1),其具有两个独特的六氢呋喃并[3,2 - b]呋喃部分。基于二维核磁共振数据的详细分析阐明了其结构,并使用改良的莫舍尔方法确定了C-5的绝对构型。海葵素-2(1)对人结肠癌Caco-2细胞和人肺腺癌A549细胞表现出强大的细胞毒性活性。
