Relamorelin (RM-131) TFA, 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 TFA is centrally penetrant. Relamorelin TFA increases growth hormone levels and accelerates gastric emptying. Relamorelin TFA has the potential for cachexia, gastroparesis, and gastric/intestinal dysmobility disorders research[1][2][3][4][5].
Relamorelin (RM-131) TFA shows ∼3 times greater affinity for GHS-1a (Ki=0.42 nM) than native ghrelin (Ki=1.12 nM). Relamorelin TFA 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].
Relamorelin (RM-131; 50-500 nmol/kg/day; s.c.; continuous infusion for 5 days) TFA decreases the loss of body mass and fat mass. Relamorelin (500 nmol/kg/day; continuous infusion for 5 days) TFA increases the food intake and weight gain in rats[1].RM-131 (250-500 nmol/kg; a single s.c.) TFA stimulates acute food intake in wt but not growth hormone secretagogue receptor (GHR) ko mice[2].

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
