Dongsha Islands, Taiwan, has led to the isolation of a known ceramide (1) and two new cerebrosides, sarcoehrenosides A (2) and B (4), along with three known cerebrosides (3, 5, and 6). The structures of the new compounds were established by spectroscopic and chemical methods. Sarcoehrenoside A (2) differs from previously known marine cerebrosides in that it possesses a rare α-glucose moiety. Compounds 1−6
在台湾东沙群岛上收集的八叶Sarcophyton ehrenbergi的化学研究导致分离出一种已知的神经酰胺(1)和两种新的脑苷,sarcoehrenosides A(2)和B(4),以及三种已知的脑苷脂((3,5,和6)。通过光谱和化学方法建立了新化合物的结构。Sarcoehrenoside A(2)与先前已知的海洋脑苷不同,因为它具有罕见的α-葡萄糖部分。化合物1 - 6 使用RAW 264.7巨噬细胞评估了它们对一小部分细菌的抗菌活性和抗炎活性。
