General description

Chemical structure: macrolide

Application

Erythromycin stearate is used to study leucocyte motility and transformation and on release in vitro of prostaglandin E2 by stimulated leucocytes. It is also used to study abnormal polymorphonuclear leucocyte migration and chemotaxis.

Biochem/physiol Actions

Erythromycin inhibits protein synthesis (elongation) at the level of transpeptidation (aminoacyl translocation A-site to P-site) by binding to the 50s subunit of the bacterial 70s rRNA complex.
