    摘要: To provide novel fluorine-containing anthracycline derivatives having high antitumor activities and a solubility in water, there have now been synthesized a 7-O-(2,6-dideoxy-2-fluoro-3-O- or -4-O- or -3,4-di-O-aminoalkanoyl-.alpha.-L-talopyranosyl)daunomycinone or -adriamycinone of general formula (I) shown below, as well as a 7-O-(3-O- or -4-O- or -3,4-di-O-aminoalkanoyl-2,6-dideoxy-2,6,6,6-tetrafluoro-.alpha.-L-talopyranosyl- or -2,6-dideoxy-6,6,6-trifluoro-.alpha.-L-lyxo-hexopyranosyl)adriamycinone of general formula (II) shown below: General formula (I) ##STR1## General formula (II) ##STR2## wherein either one or both of A.sup.1 and A.sup.2 is or are an .alpha.-amino acid residue or an .omega.-amino acid residue and T denotes a fluorine or hydrogen atom. The novel fluorine-containing anthracycline derivatives of general formulae (I) and (II) are highly active against tumors and soluble in water, and they are useful as antitumor agents administrable in the form of injectable solution.

    摘要: As new compounds are now synthetized 5-deoxy-5,5-difluoro derivatives of aminoglycosidic antibiotics of neamine, kanamycin A-series, kanamycin B-series, gentamicin-series and seldomycin-series. Further, the 1-N-(.alpha.-hydroxy-.omega.-aminoalkanoyl) derivatives are synthetized from 5-deoxy-5,5-difluorokanamycins A and B, as well as their analogues now obtained. The 5-deoxy-5,5-difluoro derivatives of the aminoglycosidic antibiotics now provided according to this invention have such antibacterial activities enhanced much more than or equal to those of the respectively corresponding parent aminoglycosidic antibiotics, while these 5-deoxy-5,5-difluoro derivatives exhibit values of the 50% lethal dosage (LD.sub.50) which are improved remarkably better when they are intravenously administered to mice, so that they have remarkedly reduced toxicities to mammals.

    摘要: A new compound, 3'-fluoro-3'-deoxykanamycin A is now provided, which is active against gram-negative and gram-positive bacteria, including kanamycin-resistant strains of bacteria and is useful as antibacterial agent for therapeutic treatment of bacterial infections. This new compound is produced by a process comprising reacting a 6-azido-2,4-di-O-protected-3,6-dideoxy-3-fluoro-.alpha.-D-glucopyranosyl bromide with the 4-hydroxyl group of a 6-O-(2'-O-protected-3'-N-protected-3'-amino-4',6'-di-O-protected-3'-deoxy-.alpha.-D-glucopyranosyl)-1,3-bis-N-protected-2-deoxystreptamine, reducing the azido group of the resulting reaction product into an amino group, and removing the remaining protective groups from the reduction product.
