Ribostamycin was found in the culture broth of Streptomyces ribosidificus by Meiji Seika Kaisha in 1970 in the course of screening aminoglycoside antibiotics. It is structurally related to neomycin but lacks the diaminoidose (glucose) moiety substituted on the ribose moiety. Ribostamycin is much less toxic than neomycin and shows strong activity against a variety of gram-positive and gram-negative bacteria, except Pseudomonas aeruginosa. It is used parenterally for therapy of urinary tract, respiratory tract, surgical, and other infections.

Ribostamycin (Vistamycin) is a broad-spectrum aminoglycoside antibiotic. Ribostamycin is effective against Gram-Negative and Gram-Positive bacterial infection. Ribostamycin also inhibits the chaperone activity of PDI[1][2].

ChEBI: An amino cyclitol glycoside that is 4,6-diaminocyclohexane-1,2,3-triol having a 2,6-diamino-2,6-dideoxy-alpha-D-glucosyl residue attached at position 1 and a beta-D-ribosyl residue attache at position 2. It is an antibiotic produced by Streptomyces ribosidificus (formerly S. thermoflavus).

Ribostamycin (SF-733) is produced by Streptomyces ribosidificus. The free base is crystallized from methanol solution. The structure has been determined by chemical methods and total synthesis has been undertaken .
