Erythromycin and motilin
WebThere have been recent advances in the development of newer motilin receptor agonists, such as ABT-229 and GM-611. Unfortunately, the use of ABT-229 as a prokinetic agent in human trials has been disappointing (25–27). GM-611 is in phase II trials in the United States, and results are eagerly awaited (28). Until such time as newer agents are ... WebThe motilin gene has a high homology sequence with that of other mammals, including humans. Suncus motilin is predicted to exist as a 117-residue prepropeptide that undergoes proteolytic cleavage to form a 22-amino-acid mature peptide. The results of RT-PCR showed that motilin mRNA is highly expressed in the upper small intestine, and low ...
