General description

Erythromycin A enol ether (EAEN) is an acidic degradation product of erythromycin A (EA) which is grouped under the macrolide antibiotic class of compounds.

Application

EAEN has been used for the analysis of EAEN as degradation product of EA in honey by ultra-performance liquid chromatography equipped with tandem quadrupole mass spectrometer (UPLC-MS/MS) with positive electrospray ionisation (ESI) operating on multiple reaction monitoring (MRM) mode and in rat′s blood plasma, serum and human urine by high performance liquid chromatography-coulometric assay. It may be used as a reference standard for the detection of EAEN in erythromycin fractions by isocratic LC with evaporative light scattering detection (ELSD) and ion trap MS and in commercial erythromycin samples by LC-MS/MS.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

We investigated the effect of an erythromycin derivative, EM523L, on interdigestive gastrointestinal motor activity and plasma motilin concentrations in three healthy volunteers using an infused catheter system. We administered doses of 500, 1000, and 2000 micrograms of EM523L to each

Studies on the physiological role of motilin, and more recently, on the relationship between motilin and erythromycin A, have been hampered by the lack of antagonists. We now have discovered such a compound. ANQ-11125 displaces motilin bound to an homogenate
