Relamorelin acetate
Based on 2 publication(s) in Google Scholar
Relamorelin (RM-131) acetate, 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 acetate is centrally penetrant. Relamorelin acetate increases growth hormone levels and accelerates gastric emptying. Relamorelin acetate has the potential for cachexia, gastroparesis, and gastric/intestinal dysmobility disorders research.

Biological Activity
Ki: 0.42 nM (GHS-1a)[1]
Relamorelin (RM-131) acetate shows ∼3 times greater affinity for GHS-1a (Ki=0.42 nM) than native ghrelin (Ki=1.12 nM). Relamorelin acetate 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[1].
