    摘要: A new semi-synthetic antibiotic, 3"-deoxystreptomycin is now provided, which is useful as an antibacterial agent and is produced from 3"-deoxydihydrostreptomycin by a process comprising oxidizing the 3'-hydroxymethyl group of 2,5,6,4",6"-penta-O-acetyl-2"-N-benzyloxycarbonyl-3"-deoxydihydrostreptomycin as prepared by skilled introduction of amino-protecting group and hydroxyl-protecting group of appropriately selected natures into 3"-deoxydihydrostreptomycin, and then removing the protective groups from the oxidation product, 2,5,6,4",6"-penta-O-acetyl-2"-N-benzyloxycarbonyl-3"-deoxystreptomycin.

    摘要: The invention provides the novel antibiotic known as daunorubicin (13057 RP) which has a powerful anti-cancer effect and is also an anti-bacterial agent. This antibiotic is a constituent of a mixture of three antibiotics, called 9865 R.P., produced by aerobic culture of one of the strains of Streptomyces, NRRL 3046 and 3045.
