BMS-604992 (EX-1314) dihydrochloride is a selective and orally active small-molecule agonist of the growth hormone secretagogue receptor (GHSR). It exhibits high-affinity binding (k i = 2.3 nM) and potent functional activity (EC 50 = 0.4 nM). Furthermore, BMS-604992 dihydrochloride has been shown to stimulate food intake in rodents.
Relamorelin (RM-131) acetate is a pentapeptide ghrelin analog that acts as a selective agonist for the ghrelin/growth hormone secretagogue receptor (GHSR). It exhibits a high affinity for the GHS-1a receptor, with a Ki value of 0.42 nM. Notably, Relamorelin acetate can cross the blood-brain barrier and target the central nervous system. This compound effectively increases growth hormone levels and promotes faster gastric emptying. Due to these properties, Relamorelin acetate holds promise for its potential applications in research related to cachexia, gastroparesis, and gastric/intestinal dysmobility disorders [4] [5].
BMS-604992 (EX-1314) free base is a selective, orally active small-molecule growth hormone secretagogue receptor (GHSR) agonist. It exhibits high-affinity binding (k i = 2.3 nM) and potent functional activity (EC 50 = 0.4 nM). Moreover, BMS-604992 free base has the ability to stimulate food intake in rodents.
Ulimorelin is a ghrelin receptor agonist (EC50: 29 nM and a Ki of 16 nM). Ulimorelin is a prokinetic agent and causes vasorelaxation through competitive antagonist action at α1-adrenoceptors.
