Three new acetylenic metabolites (1-3) were isolated from the sponge Stelletta sp. collected from Gagu-Do, Korea. On the basis of the results of combined spectroscopic analyses, the structures of these compounds were determined to be an acetylenic acid, its 2-methoxy analogue, and corresponding anhydride, respectively. The new compounds exhibited weak cytotoxicity against a human leukemia cell-line
从海绵Stelletta sp。中分离出三种新的炔属代谢产物(1-3)。从韩国Gagu-Do收集。根据组合光谱分析的结果,确定这些化合物的结构分别为炔酸,其2-甲氧基类似物和相应的酸酐。新化合物对人白血病细胞系(K562)的细胞毒性较弱。
