configuration of 3 was confirmed by single-crystal X-ray diffraction analysis for the first time. All isolated metabolites (1–14) and eight synthetic phenyl ether derivatives (12a, 14a–14g) were evaluated for their antibacterial activities in vitro. The polybromide phenyl ether 14g showed pronounced antibacterial activity against Staphylococcus epidermidis with an MIC value of 0.556 μM, stronger than that of
两个新的异戊烯化的吲哚生物碱,17-外延-notoamides Q和M(1和2),和两个新的苯基醚衍生物,cordyols d和E(9和13)中,用10种已知化合物(一起3 - 8,10 - 12,14)是从海洋来源的曲霉(Aspergillus sp。)菌。其中,1 / 5和2 / 4是一对差向异构体。新化合物的平面结构和绝对构型由大量NMR光谱数据和CD光谱确定。首次通过单晶X射线衍射分析确认了3的绝对构型。所有分离的代谢物(1 - 14)和8个合成苯基醚衍生物(12A,14A - 14克)对它们的抗菌活性进行了评价体外。聚溴苯醚14g对表皮葡萄球菌具有明显的抗菌活性 MIC值为0.556μM,比阳性对照环丙沙星(MIC = 3.13μM)强。
