Relamorelin

Research use only, not for human use.

Relamorelin(BIM28131, RM131) is a selective and potent ghrelin/growth hormone secretagogue receptor (GHSR) agonist with high affinity for GHS-1a receptor (Ki value is 0.42 ± 0.063 nM).

Relamorelin (RM-131), a pentapeptide ghrelin analog, is a selective ghrelin/growth hormone secretagogue receptor (GHSR) agonist with a Ki of 0.42 nM for GHS-1a receptor. Relamorelin is centrally penetrant. Relamorelin increases growth hormone levels and accelerates gastric emptying. Relamorelin has the potential for cachexia, gastroparesis, and gastric/intestinal dysmobility disorders research.

Relamorelin (RM-131) shows ～3 times greater affinity for GHS-1a (Ki=0.42 nM) than native ghrelin (Ki=1.12 nM). Relamorelin is 6 times more potent (EC50=0.71 nM) in activating the GHS-1a receptor than native ghrelin (EC50=4.2 nM) as assessed in vitro by calcium mobilization.

Relamorelin (RM-131; 50-500 nmol/kg/day; s.c.; continuous infusion for 5 days) decreases the loss of body mass and fat mass. Relamorelin (500 nmol/kg/day; continuous infusion for 5 days) increases the food intake and weight gain in rats.RM-131 (250-500?nmol/kg; a single s.c.) stimulates acute food intake in wt but not growth hormone secretagogue receptor (GHR) ko mice.Animal Model:F344/NTacfBR male rats implanted with tumor Dosage:50, 500 nmol/kg/day Administration:SC; continuous infusion at a rate of 0.5 μL/h for 5 d Result:Resulted in an increase in food intake (tumor/saline 41.4 g, tumor/BIM-28131 72.5 g) and weight gain (tumor/ saline -10.3%, tumor / BIM-28131 +19.5%).
