JOSAMYCIN Usage And Synthesis
Chemical PropertiesWhite or slightly yellowish powder, slightly hygroscopic.
UsesAs a 16-membered ring macrolide antibiotic with antimicrobial activity against a wide range of pathogens. Josamycin can be particularly used in the treatment of Mycoplasma infection.
DefinitionChEBI: A macrolide antibiotic produced by certain strains of Streptomyces narbonensis var. josamyceticus.
Pharmaceutical ApplicationsA naturally occurring antibiotic produced by Streptomyces narbonensis var. josamyceticus and belonging to the leucomycin group of macrolides. It is formulated for oral administration.
Many Gram-positive and Gram-negative anaerobes are susceptible, including Peptostreptococcus spp., Propionibacterium spp., Eubacterium spp. and Bacteroides spp.
After a single 1 g oral dose, a peak serum concentration of 2.74 mg/L was achieved 0.75 h after dosing. The AUC was 4.2 mg.h/L, and the apparent elimination half-life 1.5 h. Several inactive metabolites could be detected. It penetrates into saliva, tears and sweat, and achieves high levels in bile and lungs. It is mostly metabolized and excreted in the bile in an inactive form. Less than 20% of the dose appears in the urine, producing levels of around 50 mg/L.
The drug is generally well tolerated, producing only mild gastrointestinal disturbance. Its uses are similar to those of erythromycin. It is of limited availability.
