Nine new sesquiterpenoid quinones, nakijiquinones J−R (1−9), have been isolated from three collections of Okinawan marine sponges of the family Spongiidae, and the structures and configurations were elucidated from the spectroscopic data and chemical correlations. Nakijiquinones J−L (1−3), M and N (4 and 5, respectively), O (6), P and Q (7 and 8, respectively), and R (9) are new sesquiterpenoid quinones
九个新倍半萜醌,nakijiquinones J-R(1 - 9),已经从家庭Spongiidae的冲绳海绵的三个集合中分离,以及结构和构造是从光谱数据和化学相关性阐明。Nakijiquinones J-L(1 - 3),M和N(4和5,分别地),O(6),P和Q(7和8,分别地),和R(9)是具有新的倍半萜类醌(小号) -2-甲基丁胺,异戊胺,异丁胺,苯乙胺和牛磺酸残基分别连接到每个醌环上。
