抗菌引导下的网角海绵 Lamellodysidea sp 的分离。两个粒状 Dysidea 样品产生了 14 种多溴二苯醚,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屎肠球菌的药物敏感和耐药菌株表现出很强的抗菌活性,最低抑制浓度为低至亚微克mL−1,其中两种化合物以结构依赖性方式抑制大肠杆菌。
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 low- to sub-microgram mL−1 minimum inhibitory concentrations against drug-susceptible and drug-resistant strains of Staphylococcus aureus and Enterococcus faecium, and two compounds inhibited Escherichia coli in a structure-dependent manner.
