    摘要: A new antibiotic SF-1771 substance is produced by cultivating a new strain, Streptomyces toyocaensis SF-1771, in a liquid culture medium under aerobic conditions. This antibiotic may be isolated from the fermentation broth by treating the broth filtrate with a synthetic adsorbent resin for adsorption of the active compound and eluting the resin with an aqueous alcohol or aqueous acetone, followed by chromatographic purification. SF-1771 substance is a copper-containing antibiotic which shows antibacterial activity against Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. Removal of the copper component from SF-1771 substance by treatment with hydrogen sulfide, an alkali metal sulfide or a copper-chelating agent gives SF-1771-B substance containing no copper component which shows antibacterial activity as high as but a toxicity lower than SF-1771 substance.

    摘要: A new derivative of the macrolide antibiotic SF-837 substance is manufactured by treating a 9,2'-diacyl- or 9-acyl-SF-837 composition with dimethylsulfoxide and acetic anhydride, and, subsequently, with an alcohol or water-containing solvent to yield the novel compound, 9-Acyl-3"-thiomethoxymethyl-SF-837 composition. In addition to high therapeutic effectiveness and low acute toxicity, this novel compound of the present invention has the great advantages that it does not have the bitter taste originally accompanying the parent compounds, and the further advantage that it is suitable for pediatric and veterinary use.

    摘要: A 9-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance is now synthetized, which is a new compound useful in that this new 9-O-alkanoyl-3"-O-alkanoyloxymethyl derivative of the SF-837 substance exhibits an antibacterial activity comparable to that of the parent SF-837 substance but is advantageously free from the unpleasant bitter taste inherent to the SF-837 substance and is hence adapted for oral administration. A process of producing the 9-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance is also provided, which comprises hydrolysing partially and selectively a 9,2'-di-O-alkanoyl-3"-O-alkanoyloxymethyl-SF-837 substance in an aqueous alkanol or aqueous acetone. The 9,2'-di-O-alkanoyl-3"-O-alkanopyloxymethyl-SF-837 substance may be prepared by reacting a 9,2'-di-alkanoyl- or O-mono-O-alkanoyl-3"-O-thiomethoxymethyl-SF-837 substance with an alkanoic anhydride which is exemplified by acetic anhydride or propionic anhydride in the specification.
