Antibiotic A-21978 mixtures, in particular the A-21978C mixture, comprising microbiologically active, related factors Co, C1, C2, C3, C4, and Cs. A-21978 mixture and A-21978C mixture are produced by submerged aerobic fermentation of Streptomyces roseosporus NRRL 11379. The individual A-29178C factors are separated and isolated by chromatography. The A-21978 and A-2f978C mixtures; the A-21978C factors; and pharmaceutically acceptable salts thereof are antibacterial agents and improve growth promotion in poultry.
57 The present invention is directed to a chemical process for preparing the antibiotic substance denominated antibiotic L 17054 and its pharmaceutically acceptable salts by selectively hydrolyzing teicoplanin or a factor or component thereof with a concentrated strong organic acid.
57 本发明涉及一种化学工艺,通过用浓的强有机酸选择性地水解替考拉宁或其因子或组分,制备名为抗生素 L 17054 的抗生素物质及其药学上可接受的盐。
