    摘要: Zinc salts are used to effect the regio-selective acylation and alkylation of the 1-amino group of 4-O-substituted-2-deoxystreptamine-containing aminoglycosides. The 1-N-substituted derivatives of apramycin, 3'-hydroxyapramycin, certain .alpha. or .beta.-(lower alkyl)aprosaminides and certain .alpha. or .beta.-(substituted lower alkyl)-aprosaminides are new. The 1-N-substituted-4-O-substituted-2-deoxystreptamine aminoglycosides produced by the process of this invention are antibacterial agents.

    摘要: Antibiotics of the formula ##STR1## wherein R is .alpha.-3,4-di-O-methylrhamnosyl, are produced by the cultivation of Streptomyces capreolus NRRL 11429 under submerged aerobic fermentation conditions. A crude antibiotic mixture is obtained from the fermentation medium by extraction. The compounds of Formula II, III, and IV are separated from coproduced Antibiotic A201A (See U.S. Pat. No. 3,843,784) and from each other by repetitive chromatography on silica gel.
