A new antibiotic was obtained from the cultured broth of an actinomycete identified as Streptomyces capoamus, and has been named capoamycin. The structure of capoamycin was elucidated by NMR spectral analysis and chemical degradation, which revealed that capoamycin was composed of a modified benz[a]anthraquinone chromophore, a β-C-olivoside and (E, E)-2, 4-decadienoic acid. Capoamycin inhibited the growth of Gram-positive bacteria, yeasts and fungi, induced differentiation of mouse myeloid leukemia cells (Ml) and prolonged the survival periods of mice bearing Ehrlich ascites carcinoma.
一种新的抗生素是从一种名为“Streptomyces capoamus”的放线菌培养液中提取的,并命名为“卡波霉素”。通过核磁共振光谱分析和化学降解,卡波霉素的结构得以阐明,结果表明卡波霉素由一种修饰的苯并[a]蒽醌色素、β-C-橄榄苦苷和(E,E)-2,4-癸二烯酸组成。卡波霉素可抑制革兰氏阳性细菌、酵母菌和真菌的生长,诱导小鼠骨髓性白血病细胞(Ml)分化,并延长艾氏腹水癌小鼠的存活期。
