Target Validation Information
TTD ID T62306
Target Name Motilin receptor (MLNR)
Type of Target
Clinical trial
Drug Potency against Target MOTILIN Drug Info Ki = 0.36 nM [1]
Action against Disease Model Camicinal Drug Info GSK962040: a small molecule, selective motilin receptor agonist, effective as a stimulant of h uMan and rabbit gastrointestinal motility. In rabbit gastric antr uM, GSK962040 300 nmol L(-1)-10 micromol L(-1) caused a prolonged facilitation of the amplitude of cholinergically mediated contractions, to a maxim uM of 248 +/- 47% at 3 micromol L(-1). In h uMan-isolated stomach, GSK962040 10 micromol L(-1), erythromycin 10 micromol L(-1) and [Nle13]-motilin 100 nmol L(-1), each caused muscle contraction of similar amplitude. In conscious rabbits, intravenous doses of 5 mg kg(-1) GSK962040 or 10 mg kg(-1) erythromycin significantly increased faecal output over a 2-h period. [2]
