Antibacterial-guided fractionation of the Dictyoceratid sponges Lamellodysidea sp. and two samples of Dysidea granulosa yielded 14 polybrominated, diphenyl ethers including one new methoxy-containing compound (8). Their structures were elucidated by interpretation of spectroscopic data of the natural product and their methoxy derivatives. Most of the compounds showed strong antimicrobial activity with
Dictyoceratid海绵Lamellodysidea sp的抗菌引导分级。和两个Dysidea granulosa样品产生了14种多溴联苯醚,其中包括一种新的含甲氧基化合物(8)。通过解释天然产物及其甲氧基衍生物的光谱数据阐明了它们的结构。大多数化合物对金黄色葡萄球菌和粪便肠球菌的药物敏感性和耐药菌株均具有很强的抗菌活性,最低抑菌浓度为低至亚微克– 1最小抑菌浓度,并且两种化合物以结构依赖性方式抑制大肠杆菌。
