Separacenes A-D (1-4), novel polyene polyols, were isolated from Streptomyces sp. collected from the southern area of Jeju Island, Korea. The chemical structures of 1-4 were established by NMR, mass, UV, and IR spectroscopy as well as the modified Mosher's method. Separacenes A-B (1-2), which share an identical planar structure but possess different relative configurations, bear tetraene units flanked
Separacenes AD (1-4) 是一种新型多烯多元醇,是从 Streptomyces sp. 中分离出来的。采自韩国济州岛南部地区。1-4 的化学结构是通过核磁共振、质谱、紫外和红外光谱以及改进的 Mosher 方法建立的。Separacenes AB (1-2) 具有相同的平面结构但具有不同的相对构型,带有四烯单元,两侧有两个二醇部分,而立体异构的 separaracenes CD (3-4) 在两个二醇亚结构之间具有三烯部分。对苯二酚 AD 各自含有一个末端烯烃亚甲基。Separacene A 显示出对白色念珠菌异柠檬酸裂解酶的抑制活性和对结肠癌细胞系 HCT-116 和肺癌细胞系 A549 的弱细胞毒性。
