Erythromycin A N-oxide is a facile metabolite of erythromycin A.

Erythromycin A N-oxide is a minor analogue of the erythromycin complex isolated from Saccharopolyspora erythraea. The N-oxide is a facile metabolite formed in vivo which can revert to erythromycin A under reducing conditions. Despite its synthetic preparation in the 1950s, the biological activity of erythromycin A N-oxide has not been extensively studied.
