invertebrates have been relatively understudied. Herein, we report nelliellosides A and B, new secondary metabolites of the Pacific bryozoan Nelliella nelliiformis, found using NMR-guided isolation. Their structures, including absolute configurations, were elucidated using spectroscopic and chromatographic techniques. Total synthesis of the natural products and four analogues was also achieved, in addition to
海洋生物是生物活性天然产物的宝贵来源,但对苔藓无脊椎动物的研究相对较少。在本文中,我们报告了核果糖苷A和B,这是使用NMR指导分离发现的太平洋苔藓苔藓菌Nelliella nelliiformis的新的次级代谢产物。使用光谱和色谱技术阐明了它们的结构,包括绝对构型。除了评估其生物活性,特别是激酶抑制作用,还实现了天然产物和四种类似物的全合成。
