Elaiophylin (1) and two new methyl derivatives, 11-O-monomethylelaiophylin (2) and 11,11'-O-dimethylelaiophylin (3), were isolated from the mycelium cake of Streptomyces strains HKI-0113 and HKI-0114. The structures of 2 and 3 were determined by mass spectrometric and NMR investigations. Compounds 2 and 3 display antimicrobial and moderate cytotoxic activities.
从链霉菌菌株HKI - 0113和HKI - 0114的菌丝体饼中分离得到了伊来霉素(1)以及两种新的甲基衍生物,11 - O - 单甲基伊来霉素(2)和11,11'- O - 二甲基伊来霉素(3)。通过质谱和核磁共振研究确定了2和3的结构。化合物2和3具有抗菌活性和中等细胞毒性。
