Erythromycin B Use and Manufacturing

Erythromycin B (12-deoxyerythromycin A) is a minor co-metabolite of erythromycin produced Saccharopolyspora erythreae. Erythromycin B exhibits broad spectrum antibiotic activity, albeit less potent than erythromycin A. Erythromycin B played an integral part of the SAR studies of semi-synthetic erythromycins, however none reached clinical development.
