L-Cysteine (L-(+)-Cysteine) is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.

Ghrelin receptor full agonist-3 (Compound 22) is a selective, potent, orally active full agonist of the growth hormone secretagogue receptor (ghrelin receptor) with an EC50 value of 1.8 nM. It stimulates pulsatile secretion of growth hormone (GH), significantly increasing both the frequency and duration of GH release, thereby inducing a sustained rise in insulin-like growth factor-1 (IGF-1) levels. This compound is applicable for research in oncology and chronic obstructive pulmonary disease.

Ghrelin receptor full agonist-2 is a highly potent Ghrelin receptor full agonist.

Des-Gln14-Ghrelin TFA serves as a potent endogenous ligand for the growth hormone secretagogue receptor, effectively inducing increases in intracellular calcium levels ([Ca2+]i) in CHO-GHSR62 cells with an EC50 of 2.4 nM.

An endogenous ligand for the ghrelin receptor (GHS-R1a), produced by alternative splicing of the rat ghrelin gene. Potently induces Ca2+ release in cells expressing ghrelin receptors (EC50 = 2.4 nM) and stimulates GH release in vivo.

[Des-octanoyl]-Ghrelin (human) is a Non-acylated, major circulating isoform of ghrelin.

[Des-octanoyl]-Ghrelin (rat) is a Non-acylated, major circulating isoform of ghrelin.

Anamorelin (ONO-7643) is a novel ghrelin receptor agonist (EC50: 0.74 nM in the FLIPR assay).

Anamorelin Fumarate is a novel ghrelin receptor agonist (EC50: 0.74 nM in the FLIPR assay).

PF-5190457 is an effective and selective ghrelin receptor inverse agonist (pKi: 8.36).

AnaMorelin hydrochloride (RC-1291 hydrochloride) is a novel ghrelin receptor agonist(EC50 : 0.74 nM, in the FLIPR assay).

Emoghrelin, extracted from Heshouwu (Polygonum multiflorum), promotes the secretion of growth hormone by activating the ghrelin receptor [1].

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(BIM28131, RM131) is also a centrally permeable pentapeptide analog that can increase growth hormone levels and accelerate gastric emptying, and has the potential to study cachexia.

L-Cysteine hydrochloride (L-Cysteine HCl) is a conditionally essential amino acid,L-Cysteine hydrochloride suppresses ghrelin and reduces appetite in rodents and humans

L-Cysteine hydrochloride hydrate (L-Cysteine hydrochloride monohydrate) is a conditionally essential amino acid, which acts as a precursor for biologically active molecules such as hydrogen sulphide (H2S), taurine and glutathione. L-Cysteine hydrochloride hydrate suppresses ghrelin and reduces appetite in rodents and humans.

GOAT-IN-1 is an inhibitor of ghrelin O-acyltransferase (GOAT) that may be useful for the prophylaxis or treatment of diabetes, hyperlipidemia, non-alcoholic fatty liver, Alzheimer's disease, Parkinson's disease, cerebrovascular dementia, and cerebral infarction.

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.

Ibutamoren (MK-677) is a drug which acts as a potent, orally active growth hormone secretagogue, mimicking the GH stimulating action of the endogenous hormone ghrelin. It also alters the metabolism of body fat and so may have an application in the treatment of obesity.

KARI 201 is a selective, brain-penetrant, competitive inhibitor of acid sphingomyelinase (ASM) with an IC50 of 338.3 nM. Additionally, KARI 201 acts as an agonist of the growth hormone secretagogue receptor (ghrelin receptor). It is capable of improving the neuropathological characteristics of Alzheimer's disease.

KARI 201 hydrochloride is a selective, brain-penetrant, competitive inhibitor of acid sphingomyelinase (ASM) with an IC50 of 338.3 nM. It also acts as an agonist for the growth hormone-releasing peptide receptor (ghrelin receptor). Additionally, KARI 201 hydrochloride can enhance the neuropathological features of Alzheimer's disease.

(S)-PF-5190457 ((S)-PF-05190457) is the S-enantiomer of PF-5190457. PF-5190457 (PF-05190457) acts as an effective and selective inverse agonist of the growth hormone secretagogue receptor (ghrelin receptor), with a pKi of 8.36.

Capromorelin, a member of the growth hormone secretagogue (GHS) class of drugs, is a ghrelin receptor agonist and a novel therapy for stimulation of appetite in dogs with Ki value of 7 nM for hGHS-R1a and EC50 value of 3 nM for rat pituicyte. Capromorelin
