Two new antimycin A analogues, antimycin B1 and B2 (1–2), were isolated from a spent broth of a marine-derived bacterium, Streptomyces lusitanus. The structures of 1 and 2 were established on the basis of spectroscopic analyses and chemical methods. The isolated compounds were tested for their anti-bacterial potency. Compound 1 was found to be inactive against the bacteria Bacillus subtilis, Staphyloccocus aureus, and Loktanella hongkongensis. Compound 2 showed antibacterial activities against S. aureus and L. hongkongensis with MIC values of 32.0 and 8.0 μg/mL, respectively.
从海洋来源的细菌 Lusitanus 的废肉汤中分离出两种新的抗霉素 A 类似物,抗霉素 B1 和 B2 (1-2)。 1和2的结构是在光谱分析和化学方法的基础上确定的。测试了分离的化合物的抗菌效力。发现化合物 1 对枯草芽孢杆菌、金黄色葡萄球菌和 Loktanella hongkongensis 细菌没有活性。化合物2对金黄色葡萄球菌和香港李斯特菌具有抗菌活性,MIC值分别为32.0和8.0 μg/mL。
