Other notable developments[edit]

Scientists at Chugai discovered an erythromycin-derived motilin agonist called mitemcinal (GM-611 or 3′-N-dimethyl-11-deoxy-3′-N-isopropyl-12-O-methyl-11-oxo-8,9-didehydroerythromycin). Mitemcinal was believed to have strong prokinetic properties, like its parent molecule, but lack antibiotic properties. Presently, erythromycin is commonly used off-label for gastric motility indications such as gastroparesis. If mitemcinal can be shown to be as effective a prokinetic agent, it would represent an advance in the field as treatment with this drug would not carry the risk of unintentional selection of antibiotic-resistant bacteria.
