PF-04628935 is a potent antagonist inverse agonist of the ghrelin receptor, growth hormone secretagogue receptor 1a (GHS-R1a) with an IC50 of 4.6 nM. PF-04628935 is orally bioavailable and brain penetrant.

SM-130,686 is a potent, orally-active agonist of the ghrelin/growth hormone secretagogue receptor (GHSR) and growth hormone secretagogue. It has around half the potency of the endogenous agonist ghrelin as a stimulator of growth hormone release.

Tabimorelin is a potent, orally-active agonist of the ghrelin/growth hormone secretagogue receptor (GHSR) and growth hormone secretagogue.

YIL781 is a ghrelin receptor antagonist (GHS-R1a) (Ki = 17 nM) with no significant affinity for the motilin receptor (Ki = 6 μM).

Obestatin is a 23 amino acid peptide hormone with a conserved C-terminal glycine residue and amidation site that is formed by cleavage of the ghrelin and obestatin prepropeptide.1It binds to the orphan receptor GPR39 (Kd= 1 nM) and stimulates cAMP production in CHO and HEK293 cells overexpressing human GPR39. Obestatin inhibits contraction of isolated mouse jejunum muscle strips induced by ghrelin .In vivo, obestatin (12.5-1,000 nmol/kg) suppresses food intake in a time- and dose-dependent manner and reduces body weight gain and gastric emptying in mice. Obestatin (0.22 g per animal) also reduces food intake and glucose response without affecting plasma insulin responses in fasted high-fat diet fed mice.2 1.Zhang, J.V., Ren, P.C., Avsian-Kretchmer, O., et al.Obestatin, a peptide encoded by the ghrelin gene, opposes ghrelin's effects on food intakeScience310(5750)996-999(2005) 2.Subasinghage, A.P., Green, B.D., Flatt, P.R., et al.Metabolic and structural properties of human obestatin {1-23} and two fragment peptidesPeptides31(9)1697-1705(2010)

JMV3002 is a potent ghrelin receptor antagonist with an IC50 value of 1.1 nM in vitro. At 80 μg kg, JMV3002 inhibits hexarelin-stimulated food intake by up to 98% in rats. It does not induce growth hormone release nor inhibit hexarelin-stimulated growth hormone secretion at a dose of 160 μg kg in infant rats.

AZ-GHS-22 is an inverse agonist of the growth hormone secretagogue receptor 1a (GHS-R1a), which is also known as the ghrelin receptor.1It binds to GHS-R1a with an IC50value of 0.77 nM. AZ-GHS-22 decreases food intake in mice by 54% in the first two hours after administration of a 100 mg/kg dose. 1.McCoull, W., Barton, P., Brown, A.J.H., et al.Identification, optimization, and pharmacology of acylurea GHS-R1a inverse agonistsJ.

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].

Macimorelin Acetate (EP-1572), an orally active growth hormone (GH) secretagogue and a ghrelin receptor (GHSR) agonist, stimulates GH release. It is utilized in research focusing on adult growth hormone deficiency (AGHD) and Cancer Anorexia-Cachexia Syndrome (CACS).
