EM574 is a motilin receptor agonist with an IC50 value of 6.17 nM for binding to rabbit gastric antral smooth muscle homogenates in a radioligand binding assay.1 It also binds to human smooth muscle homogenates in a radioligand binding assay (Kd = 7.8 nM).2 EM574 induces contraction of isolated rabbit, but not rat or guinea pig, intestine (EC50 = 5.5 nM).1 It increases antral motility and enhances gastric emptying in canine models of gastroparesis when administered intraduodenally at a dose of 0.03 mg/kg following a semi-solid meal.3
