A chemical investigation of the MeOH extract of a marine sponge Haliclona (Reniera) sp., collected off the coast of Ulleung Island, Korea, led to the isolation of thirteen new cerebrosides (1--3, 5--14), along with a known analogue (4). Their structures were elucidated on the basis of 1D and 2D NMR spectroscopy, MS spectrometry, and chemical method. The major new features of these glucocerebrosides
对从韩国Ulleung岛海岸收集的海洋海绵Haliclona(Reniera)sp。的MeOH提取物进行的化学研究导致分离出13种新的脑苷(1--3、5--14),以及已知的类似物(4)。在1D和2D NMR光谱,MS光谱和化学方法的基础上阐明了它们的结构。这些葡糖脑苷脂的主要新特征是C15和C19酰基链,长(C24-C28)酰基链或酰基链的S-构型。值得注意的是,在同一样品中观察到酰基链的R-和S-构型。
