Syriacin, a novel unusual sulfated ceramide glycoside with branched very-long-chain fatty acid, i.e., (all Z)-34S-methylhexatriaconta-5,9,12,15,18,21-hexaenoic acid, has been isolated from the freshwater sponge Ephydatia syriaca. Its structure was identified by means of extensive spectroscopic analysis (IR, UV, 2D NMR, MS, CD) and chemical degradation. Syriacin showed antifeeding activity against goldfish
叙利亚新霉素,是一种新型的不寻常的硫酸化神经酰胺糖苷,带有支链超长链脂肪酸,即(所有Z)-34 S-甲基六六碳六烯酸-5,9,12,15,18,21-己烯酸,已从中分离出来。淡水海绵紫藻(Ephydatia syriaca)。通过广泛的光谱分析(IR,UV,2D NMR,MS,CD)和化学降解来鉴定其结构。叙利亚霉素在自然浓度(〜10μg/ ml)下显示出对金鱼的拒食活性。
