Erythromycin A enol ether

Erythromycin A enol ether is a decomposition product of the macrolide antibiotic, erythromycin A (Cay-16486). Erythromycin A enol ether does not retain the antibiotic properties of erythromycin A and has been identified as a beta-turn mimic of the peptide hormone motilin, causing duodenal contractions and gastrointestinal distress. This compound has been used to determine the binding characteristics of ligands of the motilin receptor.Formal Name: 8,9-didehydro-9-deoxo-6-deoxy-6,9-epoxy-erythromycin. CAS Number: 33396-29-1.
