    摘要: A new and useful 1-N-[(S)-.alpha.-hydroxy-.omega.-aminoacyl]derivative of an aminoglycosidic antiobiotic, including its deoxy derivative, such as kanamycin B, 3'-deoxyneamine, 3',4'-dideoxyneamine, 3',4'-dideoxyribostamycin or 3', 4'-dideoxykanamycin B is now synthetized from the parent substance, aminoglycosidic antibiotic. The new 1-N-[(S)-.alpha.-hydroxy-.omega.-aminoacyl] derivative shows a wider and/or higher antibacterial activity than the parent substance and is useful in the treatment of infections by gram-negative and gram-positive bacteria, including drug-resistant strains thereof. The preparation of this new derivative may be made by 1-N-acylating the parent aminoglycosidic antibiotic with (S)-.alpha.-hydroxy-.omega.-aminocarboxylic acid with the amino group being protected, and chromatographically separating the acylated products to isolate the desired 1-N-acyl derivative, followed by the removal of the amino-protecting group.
