Two new cytotoxic macrolides, amphidinolides R (1) and S (2), were isolated from the cultured marine dinoflagellate Amphidinium sp. and their structures including absolute configuration were elucidated on the basis of spectroscopic data as well as chemical experiments. In a feeding experiment of 13C-labeled succinic acid into a culture of Amphidinium sp., no enrichment of the 13C NMR signal intensity
两种新的细胞毒性大环内酯类,两性内酯R(1)和S(2),从培养的海洋鞭毛鞭状菌Amphidinium sp中分离出来。根据光谱数据和化学实验阐明了它们的结构,包括绝对构型。在将13 C标记的琥珀酸进料到Amphidinium sp。的培养实验中,未观察到任何碳的安非他命J(3)(该鞭毛中最丰富的大环内酯)的13 C NMR信号强度富集。
