PG 106 acetate is an effective and selective antagonist of the human melanocortin 3 (hMC3) receptor with an IC50 of 210 nM. PG 106 acetate has no activity with the hMC5 receptor and hMC4 receptors with an EC50 of 9900 nM.

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) can inhibit the synthesis of melanin, which makes it of interest for treating certain skin conditions.

α-MSH (MSH, amide) is amide stimulates melanocortin 1 receptor that results in the activation of adenylyl cyclase.

Ac-DArg-c[Cys-Glu-His-DPhe-Arg-Trp-Cys]-NH2 is a synthetic cyclic octapeptide acting as a melanocortin-4 receptor (MC4R) agonist, significantly elevating heart rate and blood pressure [1].

ACTH (7-38) (human) is a fragment (7-38) of the full human adrenocorticotropic hormone (ACTH (1-39)), also known as corticotropin inhibitory peptide (CIP). It functions as an antagonist to the ACTH receptor and lacks corticosteroid activity [1].

Tetrapeptide-1, a bioactive peptide known for its antioxidant properties, is frequently cited as an ingredient in cosmetics [1].

TCMCB07 TFA is a cyclic nonapeptide and an orally active, brain-penetrating antagonist of the melanocortin receptor 4 (MC4R), playing a significant role in managing cachexia [1].

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.

Melanotan I is a non-specific melanocortin receptor (MCR) agonist, an α-melanocyte-stimulating hormone (α-MSH) analog, which is injected subcutaneously to increase the amount of melanin in the skin Melanotan I is used as an adjunct to tanning Melanotan I has been used for the prevention of sunlight-induced skin cancers Melanotan I has been used in the study of melanoma and for male erectile dysfunction Melanotan I may be used to prevent sun-induced skin cancer and may be used to study melanoma and male erectile dysfunction.

Melanotan (MT)-II, a synthetic melanocortin receptor agonist, is an analogue of the peptide hormone α-melanocyte-stimulating hormone (α-MSH).

Neuropeptide EI, rat acetate Displays functional MCH-antagonist and MSH-agonist activity in different behavioral paradigms.

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.
