meroterpenoids avinosol (1), 3'-aminoavarone (2), and 3'-phenethylaminoavarone (3) have been isolated from the marine sponge Dysidea sp. collected in Papua New Guinea, and their structures were elucidated by analysis of spectroscopic data. Avinosol (1), which is apparently the first example of a naturally occurring meroterpenoid-nucleoside conjugate, showed antiinvasion activity in a cell-based assay.
[结构:见正文]从海洋海绵Dysidea sp。中分离出了新的甲氧类胡萝卜素avinosol(1),3'-aminoavarone(2)和3'-phenethylaminoavarone(3)。收集了在巴布亚新几内亚的数据,并通过分析光谱数据阐明了它们的结构。Avinosol(1),显然是天然存在的类萜金属-核苷结合物的第一个实例,在基于细胞的测定中显示出抗侵袭活性。
