从海洋甲藻Gambierdiscus toxicus的培养物中分离到一种新的雪卡毒素同系物--雪卡毒素-4A（ciguatoxin-4A，CTX-4A），根据光谱数据确定其结构为52-epiciguatoxin-4 B。色谱和光谱比较表明，CTX 4A与一种结构不明的同系物Scaritoxin或SG 1相同。
A new ciguatoxin congener, ciguatoxin-4A (CTX4A), was isolated from cultures of marine dinoflagellate Gambierdiscus toxicus, and its structure was elucidated to be 52-epiciguatoxin-4B on the basis of spectroscopic data. Chromatographic and spectral comparisons indicated that CTX4A was identical with a structurally unelucidated congener known as scaritoxin or SG1.
