mc4-r

SHU 9119 is an effective human melanocortin 3 and 4 receptors (MC3/4R) antagonist and a partial MC5R agonist (IC50: 0.23, 0.06, and 0.09 nM for human MC3R, MC4R and MC5R, respectively).

[D-Trp8]-γ-MSH acetate(321351-81-9 free base) is a selective melanocortin 3 (MC3) receptor agonist (IC50 values are 6.7, 340 and 600 nM for human MC3, MC5 and MC4 receptors respectively) and displays anti-inflammatory efficacy.

Adrenocorticotropic Hormone (ACTH) (4-10), human is a potent agonist of the melanocortin receptor (MC4R).

MCL0020 is a potent and selective melanocortin MC4 receptor antagonist (IC50 values are 11.63, 1115, and >10,000 nM at MC4, MC3, and MC1 receptors, respectively). It significantly reverses stress-induced anorexia without affecting food intake in free-feeding rats and exhibits anxiolytic-like activity in vivo.

HS024 is a highly potent melanocortin MC4 receptor antagonist (Ki values are 0.29, 18.6, 5.45 and 3.29 nM for cloned human MC4, MC1, MC3 and MC5 receptors respectively). Increases food intake, and blocks α-MSH- and MTII-induced hypotension and bradycardia in rats, following central administration in vivo.

Beta-MSH (1-22) (human) acetate (Beta-MSH (1-22) (human) acetate (17908-57-5 Free base)) , is an endogenous melanocortin-4 receptor (MC4-R) agonist.

Setmelanotide (RM-493) is a selective melanocortin-4 receptor agonist with EC50 values of 0.27 and 0.28 nM for human and rat MC4R. Setmelanotide enhances cAMP signaling, demonstrates functional selectivity, activates sympathetic preganglionic neurons to influence blood pressure, and is widely used to probe MC4R-MRAP2 interactions. Setmelanotide contributes to obesity-related research by modulating hunger and satiety circuits, reversing risperidone-induced weight gain in mice, and helping characterize MC4R variants in pediatric metabolic disorders. The anti-inflammatory actions of Setmelanotide in astrocytoma cells and the utility in combination with calorie restriction further highlight its broad value in metabolic and neuroendocrine research.

Setmelanotide Acetate(920014-72-8 free base) (RM-493 Acetate) is a selective agonist of melanocortin 4 receptor (MC4R)(human and rat MC4R with EC50s of 0.27 nM and 0.28 nM, respectively).

Nonapeptide-1 (Melanostatine-5) acetate salt is a peptide hormone that functions as a selective and competitive antagonist of the melanocortin 1 receptor (MC1R) with a binding affinity (K i) of 40 nM. It effectively inhibits α-MSH-induced increases in intracellular cyclic AMP (cAMP) and melanosome dispersion in melanocytes, with inhibitory concentrations (IC 50) of 2.5 nM and 11 nM, respectively. By inhibiting melanin synthesis, Nonapeptide-1 acetate salt is used in research related to skin pigmentation, adrenal gland steroid production regulation, and skin cancer [1] [2] [3].

Nonapeptide-1 (Melanostatine™ 5) can inhibit the synthesis of melanin, which makes it of interest for treating certain skin conditions.

β-Melanocyte Stimulating Hormone (MSH), human (Synonyms: Beta-MSH (1-22) (human)) β-Melanocyte Stimulating Hormone (MSH), human, a 22-residue peptide, acts as an endogenous melanocortin-4 receptor (MC4-R) agonist.

beta-MSH, human is an endogenous peptide hormone and neurotransmitter produced by pro-opiomelanocortin (POMC), and is also an agonist of MC4-R (melanocortin 4 receptor).
