Five new ceramides, neritinaceramides A (1), B (2), C (3), D (4) and E (5), together with six known ceramides (6-11), two known alkyl glycerylethers (12 and 13) and a known nucleoside (14), were isolated from marine bryozoan Bugula neritina, which inhabits the South China Sea. The structures of the new compounds were elucidated as (2S,3R,3'S,4E,8E,10E)-2-(hexadecanoylamino)-4,8,10-octadecatriene-l
五种新型神经酰胺,神经酰胺 A (1)、B (2)、C (3)、D (4) 和 E (5),以及六种已知神经酰胺 (6-11)、两种已知烷基甘油醚(12 和 13)和一种已知的核苷 (14),是从栖息在南海的海洋苔藓虫 Bugula neritina 中分离出来的。新化合物的结构被阐明为 (2S,3R,3'S,4E,8E,10E)-2-(十六烷酰氨基)-4,8,10-十八碳三烯-1,3,3'-三醇 (1), ( 2S,3R,2'R,4E,8E,10E)-2-(十六烷酰氨基)-4,8,10-十八碳三烯-1,3,2'-三醇 (2), (2S,3R,2'R, 4E,8E,10E)-2-(十八烷酰氨基)-4,8,10-十八碳三烯-1,3,2'-三醇 (3), (2S,3R,3'S,4E,8E)-2-(十六烷酰氨基) -4,8-十八碳二烯-1,3,3'-三醇 (4) 和 (2S,3R,3'S,4
