    • The present invention relates to new compound nanaomycin A and derivatives thereof represented by general formula: ##STR1## in which (a) R is H and R' is OH (nanaomycin A),(b) R is H and R' is NH.sub.2 (nanaomycin C),(c) R is COCH.sub.3 and R' is OH (acetylnanaomycin A), and(d) R is H and R' is OCH.sub.3 (nanaomycin A methyl ester).Nanaomycin A is a new compound of quinone type and its acute toxicity (LD.sub.50, intra-penetrial injection) in mice is 28.2 mg/Kg. Nanaomycin A and derivatives thereof are active on Gram-positive bacteria, trichophyton and mycoplasma and are useful as a medicament for humans and animals. Nanaomycins A and C are produced by culturing a nanaomycin-producing strain belonging to the genus Streptomyces aerobically in a medium to accumulate nanaomycins A and C in the cultured broths. The derivatives acetylnanaomycin A and nanaomycin A methyl ester have similar properties to those of nanaomycin A.
    • 本发明涉及由以下通式表示的新化合物纳那霉素A及其衍生物:其中(a)R是H,R'是OH(纳那霉素A),(b)R是H和R' 是NH2(纳那霉素C),(c)R是COCH 3,R'是OH(乙酰氨基霉素A),和(d)R是H,R'是OCH 3(纳诺霉素A甲酯)。 Nanaomycin A是醌类的新化合物,其在小鼠中的急性毒性(LD50,内渗注射)为28.2mg / Kg。 纳诺霉素A及其衍生物对革兰氏阳性菌,毛毛虫和支原体具有活性,可用作人和动物的药物。 Nanaomycins A和C通过在培养基中培养产生链霉菌属的链霉菌属的纳米霉素生产菌株在培养基中培养以在培养的肉汤中积累纳米菌素A和C而产生。 乙酰纳他霉素A和纳那霉素A甲酯的衍生物具有与纳那霉素A相似的性质。

    • The present invention relates to new compound designated as nanaomycin B represented by general formula: ##STR1## Nanaomycin B is a quinone type and is active on mycoplasma, Gram-positive bacteria and trycophyton. This compound is useful as a medicament for infectious diseases of humans and animals caused by a parasite of trichophyton or mycoplasma etc. The acute toxicity (LD.sub.50, intra-penetrial injection) in mice of this compound is 169 mg/kg. Nanaomycin B is produced by fermentation in which a nanaomycin-producing strain belonging to the genus Streptomyces is cultured in a medium under aerobic conditions and the accumulated nanaomycin B in the cultured broths is recovered therefrom.
