27-deoxylyngbyabellin A (4) and lyngbyabellin J (5), a novel macrolide of the laingolide family, laingolide B (6), and a linear modified peptide, lyngbyapeptin D (7), along with known lyngbyabellins A and B, lyngbyapeptin A, and lyngbyaloside. The structures of 1−7 were elucidated by a combination of NMR spectroscopic and mass spectrometric analysis. Compounds 1−6 were either brominated (1−3) or chlorinated (4−6)
来自关岛阿普拉港浅滩礁的海洋蓝藻Lyngbya bouillonii 的收集提供了三种迄今为止未描述的糖苷大环内酯 lyngbyaloside 类似物,即 2- epi- lyngbyaloside ( 1 ) 和区域异构体 18 E - 和 18 Z- lyngbyalosides (2和3)。同时,我们发现了破坏细胞骨架肌动蛋白的 lyngbyabellins 的两种新类似物,27-脱氧林比林 A ( 4 ) 和 林比林 J ( 5 ),莱戈内酯家族的一种新型大环内酯,林戈内酯 B ( 6 ) 和线性修饰肽 D lyngbyap ( 7),以及已知的 lyngbyabellins A 和 B、lyngbyapeptin A 和 lyngbyaloside。的结构1 - 7通过NMR光谱和质谱分析的组合阐明。化合物1 - 6被溴化 ( 1 - 3 ) 或氯化 ( 4 - 6 ),这与卤化是许多海洋天然产物的标志一致。由于存在
