enamide with an enol ether, was isolated from the marine cyanobacterium Moorea bouillonii. The gross structure was established by spectroscopic analyses, and the relative stereochemistry was elucidated on the basis of the analyses of NOESY correlations and 1H–1H coupling constants. The absolute configuration was determined on the basis of the chiral HPLC analysis of the N-Me-Leu derived from kanamienamide
从海洋蓝藻Moorea bouillonii中分离出一种Kanenaenamide,它是一种带有烯醇醚的酰胺。通过光谱分析确定了总体结构,并在分析NOESY相关性和1 H– 1 H耦合常数的基础上阐明了相对立体化学。绝对构型基于衍生自卡那酰胺的N -Me-Leu的手性HPLC分析确定。这是天然产物的第一个报道,该产物具有与烯醇醚相邻的N -Me-烯酰胺。Kanamienamide对HeLa细胞显示生长抑制活性,IC 50值为2.5μM,并诱导凋亡样细胞死亡。
