    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: As new compounds are provided 9,3",4"-trialkanoyl SF-837 M.sub.1 substances which have therapeutically useful antibacterial activity and do not show any objectionable long-lasting bitter taste upon its oral administration. These 9,3",4"-trialkanoyl SF-837 M.sub.1 substances may be prepared from SF-837 substance, 9,2',3"-tri-acetyl SF-837 M.sub.1 substance, 9,2'-di-acetyl SF-837 substance, 9-propionyl SF-837 substance or 9,2'-dipropionyl SF-837 substance by acylating the latter with an alkanoic acid anhydride at 50.degree.-120.degree. C to produce the corresponding 9,2',3",4"-tetra-alkanoyl SF-837 M.sub.1 substance and occasionally the 9,18,2',3",4"-penta-alkanoyl SF-837 M.sub.1 substance, with involving the shift of the 4"-alkanoyl group to the 3"-hydroxyl group. Partial and selective hydrolysis of the 9,2',3",4"-tetra-alkanoyl SF-837 M.sub.1 substance and/or the 9,18,2',3",4"-penta-alkanoyl SF-837 M.sub.1 substance so produced gives the desired 9,3",4"-tri-alkanoyl SF-837 M.sub.1 substance.

    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.
