General description

Chemical structure: aminoglycoside

Application

Ribostamycin is a broad-spectrum antimicrobial isolated from Streptomyces ribosifidicus. It is used in pharmacokinetic and nephrotoxicity studies.

Biochem/physiol Actions

Aminoglycosides, such as ribostamycin, bind to the bacterial 30S and 50S ribosomal subunit, which inhibits the translocation of the peptidyl-tRNA from the A-site to the P-site. This causes misreading of mRNA which makes bacteria unable to make essential proteins. It also inhibits the chaperone activity of protein disulfide isomerase (PDI).

Other Notes

Keep container tightly closed in a dry and well-ventilated place.

The nephrotoxicity of ribostamycin and gentamicin was compared by urinalysis using 18 parameters. When a dose of 40 mg/kg per day was administered intramuscularly to Fischer rats for 14 days, ribostamycin caused little change of parameters in urine volume, urine
