Verdamicin, a new broad spectrum aminoglycoside antibiotic.
نویسندگان
چکیده
Verdamicin is a new aminoglycoside antibiotic isolated from fermentation broths of a species of the genus Micromonospora, M. grisea. It has been differentiated from other known related antibiotics by a variety of chemical and biological methods. Its in vitro and in vivo spectrum of activity appears to be similar to those of gentamicin and sisomicin.

In vivo antibacterial activity of vertilmicin, a new aminoglycoside antibiotic.
Vertilmicin is a novel aminoglycoside antibiotic with potent activity against gram-negative and -positive bacteria in vitro. In this study, we further evaluated the efficacy of vertilmicin in vivo in systemic and local infection animal models. We demonstrated that vertilmicin had relatively high and broad-spectrum activities against mouse systemic infections caused by Escherichia coli, Klebsiel...
متن کاملComparison of in vitro antibacterial activities of gentamicin and verdamicin.
The in vitro activities of verdamicin and gentamicin were studied in parallel against 1,049 bacterial isolates. Verdamicin demonstrated activity similar to that of gentamicin against members of the family Enterobacteriaceae and against Pseudomonas aeruginosa at 2 and 8 mug/ml, respectively. Proteus rettgeri and Providencia stuartii were notably more susceptible to verdamicin. The new aminoglyco...
متن کاملBroad-spectrum peptide inhibitors of aminoglycoside antibiotic resistance enzymes.
The action of aminoglycoside antibiotics is inhibited by chemical modification catalyzed by aminoglycoside inactivating enzymes, which bind these cationic saccharides with active site pockets that contain a preponderance of negatively charged residues. In this study, it was observed that several cationic antimicrobial peptides, representing different structural classes, could serve as inhibitor...
متن کاملBoholmycin, a new aminoglycoside antibiotic. I. Production, isolation and properties.
A novel aminoglycoside antibiotic, boholmycin, was produced by Streptomyces hygroscopicus H617-25 isolated from a soil sample collected in Bohol Island, the Philippines. It has a pseudotetrasaccharide structure composed of a heptose, two aminosugars and dicarbamoyl-scyllo-inositol. Intrinsic antibacterial activity of boholmycin is weak but it exhibits broad spectrum activity against Gram-positi...
متن کاملAntibiotic G-418, a new Micromonospora-produced aminoglycoside with activity against protozoa and helminths: fermentation, isolation, and preliminary characterization.
Antibiotic G-418 is a new aminoglycoside produced as the major component by a new species of Micromonospora, M. rhodorangea NRRL 5326. The antibiotic is prepared by submerged fermentation in a soybean-dextrin medium. Antibiotic G-418 is adsorbed on a cationic-exchange resin and separated from other impurities by passing it down a Dowex (1 x 2) resin column. The antibiotic, which contains 2-deox...
