Motilin Receptor Agonist

Motilin (26-47), human, porcine is an endogenous motilin receptor ligand with K_i and EC₅₀ of 2.3 nM and 0.3 nM in a Chinese hamster ovary cell line.

DS-3801b is a potent and non-macrolide agonist of GPR38. DS-3801b is expected to be novel gastrointestinal prokinetic agents for the research of functional gastrointestinal disorders such as gastroparesis and chronic constipation.

KC-11458 is a motilin agonist. KC-11458 can accelerate gastric emptying.

[Leu13]-Motilin (KW-5139) is a motilin analogue. [Leu13]-Motilin stimulates gastrointestinal motility in the rabbit. [Leu13]-Motilin causes concentration-dependent contractions of the gastric antrum, duodenum, jejunum, ileum and the descending colon in vitro.

Mitemcinal fumarate is an oral motilium agonist. Studies in rabbits and dogs have shown that it can promote defecation without causing severe diarrhea, increase stool weight without increasing water content in the rabbit constipation model, and reduce the time to first defecation in dogs. Mitemcinal fumarate may be a constipation suppressant due to its early onset and short duration of action.

EM-523 is a motilin agonist and an erythromycin derivative. EM-523 has pED₅₀ values of 8.19 and 6.08 for promoting contractions in rabbit small intestinal tissue and human duodenal tissue, respectively. EM-523 can be used in the research of gastrointestinal diseases.

Mitemcinal (GM 611) is an oral motilin receptor agonist. Studies in rabbits and dogs have shown that it can promote defecation without causing severe diarrhea, increase stool weight without increasing water content in the rabbit constipation model, and reduce the time to first defecation in dogs. Mitemcinal may be a constipation suppressant due to its early onset and short duration of action.

EM574 is a potent motilin receptor agonist in the human gastric antrum and rabbit gastrointestinal tract in vitro. EM574 is an erythromycin derivative.

[Nle13]-Motilin, a motilin analogue, is a motilin receptor agonist.

OHM 11638 (Atilmotin), an analogue of the (1-14) fragment of porcine motilin, is a motilin receptor agonist with a pK_d of 8.94 for the motilin receptor. OHM 11638 affects esophageal, lower esophageal sphincter (LES), and gastric motility. OHM 11638 increases LES and gastric pressures, OHM 11638 can be used as prokinetic agents.
