Biological Activity

Description Ribostamycin Sulfate(Vistamycin Sulfate,Landamycine) is an aminoglycoside antibiotic, containing a neutral sugar moiety, and is produced by Streptomyces ribosidificus.
In vitro

Ribostamycin inhibits the chaperone activity of protein disulfide isomerase (PDI), but it does not inhibit the isomerase activity, a 100:1 molar ratio of ribostamycin to PDI is almost sufficient to completely inhibit the chaperone activity of PDI. Ribostamycin binds to purified bovine PDI with KD of 0.319 mM. Ribostamycin is especially effective against the gentamicin-resistant bacterium Klebsiella pneumoniae, which possesses aminoglycoside-modifying enzymes. [1] Ribostamycin exhibits antimicrobial activity against B. burgdorferi isolates with MIC of 18.7 mg/L. [2] Ribostamycin (16 mcg/mL) inhibits 100% of the P. stagnora strains and 95% of the P. wickerhamii strains, while Ribostamycin (16 mcg/mL) inhibits 100% of the P. zopfii strains. [3]

In vivo

Ribostamycin (400 mg/kg/day) shows the weakest ototoxicity against the cochlea and vestibular organs in guinea pigs. Ribostamycin (400 mg/kg/day), causing the weakest ototoxicity, shows a low drug concentration in the inner ear fluid of of guinea pigs. [4]
