What is ERYTHROMYCIN B?

The Uses of ERYTHROMYCIN B

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.

The Uses of ERYTHROMYCIN B

Erythromycin B is a co-metabolite of Erythromycin A (E649950), an antibacterial agent.

Definition

ChEBI: Erythromycin B is an erythromycin that consists of erythronolide B having 2,6-dideoxy-3-C-methyl-3-O-methyl-alpha-L-ribo-hexopyranosyl and 3,4,6-trideoxy-3-(dimethylamino)-beta-D-xylo-hexopyranosyl residues attahced at positions 4 and 6 respectively. It is functionally related to an erythronolide B.
