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
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 K_D 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
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]

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
