General description

Chemical structure: macrolide

Application

Josamycin is used to study the modification of phagocytosis and cytokine production by macrolide antibiotics, immunomodulatory effects, the suppression of matrix metalloproteinase production as well as study bacteria protein synthesis at the level of the the 23S rRNA, 50S ribosomal subunit.

Biochem/physiol Actions

Josamycin inhibits bacterial protein biosynthesis by inhibiting peptidyltransferase and ribosomal translocation, and depleting the intracellular pools of aminoacyl-tRNAs available for protein synthesis by drop-off and incomplete peptidyl-tRNA hydrolase activity. It slows down formation of the first peptide bond of a nascent peptide in an amino acid-dependent way and inhibits formation of the second or third peptide bond.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

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

It is well known that low-dose and long-term administration of macrolide antibiotics favourably modify the clinical status of chronic airway inflammatory diseases. However, the therapeutic mode of action of macrolide antibiotics is not well understood. The present study aimed to

The aim of this study was to determine whether pre-incubation of peritoneal or splenic cells with different doses of the macrolides erythromycin A (14-membered ring), azithromycin (15-membered ring) and josamycin (16-membered ring) affects their phagocytic activity or cytokine production.
