The structure of efrotomycin.
نویسندگان
چکیده
The antibiotic efrotomycin (I), C59H88N2O20, was isolated from cultures of Nocardia lactamdurans as an amorphous yellow powder. Mass spectral and NMR analyses show that the compound is a glycoside of the known antibiotic aurodox (II), C44H62N2O12. Ozonolysis and hydrolysis of I produced the disaccharide V, 6-deoxy-4-O-(6-deoxy-2,4-di-O-methyl-alpha -L-mannopyranosyl)-3-O-methyl-beta-D-allopyranose. This disaccharide is attached to the 4-hydroxyl group of the hexahydropyran substructure of aurodox via a beta-linkage to C-1 of the allose.

Antibacterial activity of heneicomycin.
Heneicomycin is structurally similar to efrotomycin, mocimycin (kirromycin) and X-5108 (goldinomycin). Comparisons were limited because of the small supplies available. All antibiotics show the same in vitro antibacterial spectrum although some test cultures were less sensitive to efrotomycin. Heneicomycin compared favorably with efrotomycin when given subcutaneously or per os against infection...
متن کاملA resting cell system for efrotomycin biosynthesis.
Efrotomycin, a modified polyketide antibiotic with utility as a growth permittant in the animal industry, is produced by Nocardia lactamdurans. A resting cell system has been developed to facilitate biosynthetic studies. Washed cells harvested from oil-based medium at 64 hours and resuspended in buffer produce up to 700 mg/ml efrotomycin in 60 hours when supplemented with a carbon source, optim...
متن کاملUK-69,753, a novel member of the efrotomycin family of antibiotics. II. Structure determination and biological activity.
A novel antibiotic, UK-69,753, has been isolated from a submerged fermentation of Amycolatopsis orientalis strain N731-15. UK-69,753 has been assigned the structure 1 using spectroscopic means, primarily by NMR analysis. UK-69,753 is a glycoside of factumycin (A40A), a previously reported member of a small group of antibiotics related to aurodox and efrotomycin. UK-69,753 was shown to have pote...

(Received for publication May 26, 1979) Efrotomycin1) is a narrow spectrum antibiotic which is most active in vitro against representative species of Pasteurella, Moraxella and Corynebacterium2) . The in vivo activity, however, is much better than one would expect f...
متن کاملInhibition of bacterial protein synthesis by elongation-factor-Tu-binding antibiotics MDL 62,879 and efrotomycin.
MDL 62,879 (formerly GE 2270 A) is a novel antibiotic active against Gram-positive bacteria by inhibiting protein synthesis. MDL 62,879 is not active against Gram-negative bacteria, but inhibits cell-free protein synthesis in extracts from Escherichia coli, and shows a high binding affinity for its elongation factor Tu (EF-Tu). We prepared ribosomes and protein-synthesis elongation factors from...
