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).

SHU 9119 acetate is a well-known antagonist of human melanocortin 3 and 4 (hMC3R, hMC4R) receptors and a partial hMC5R agonist. The IC50 values of human MC3R, MC4R and MC5R is 0.23, 0.06, and 0.09 nM respectively.

Bremelanotide is a synthetic peptide analog of alpha-MSH and is an agonist at melanocortin receptors including the MC3R and MC4R.

α-Melanocyte-stimulating hormone (α-MSH) is a 13-amino acid peptide hormone produced by post-translational processing of proopiomelanocortin (POMC) in the pituitary gland, as well as in keratinocytes, astrocytes, monocytes, and gastrointestinal cells.1It is an agonist of melanocortin receptor 3 (MC3R) and MC4R that induces cAMP production in Hepa cells expressing the human receptors (EC50s = 0.16 and 56 nM, respectively).2α-MSH (100 pM) reducesS. aureuscolony formation andC. albicansgerm tube formationin vitro.3It inhibits endotoxin-, ceramide-, TNF-α-, or okadaic acid-induced activation of NF-κB in U937 cells.1α-MSH reduces IL-6- or TNF-α-induced ear edema in mice.4It also prevents the development of adjuvant-induced arthritis in rats and increases survival in a mouse model of septic shock. Increased plasma levels of α-MSH are positively correlated with delayed disease progression and reduced death in patients with HIV.1 1.Catania, A., Airaghi, L., Colombo, G., et al.α-melanocyte-stimulating hormone in normal human physiology and disease statesTrends Endocrinol.

PG106 TFA is a potent, selective antagonist of the human melanocortin 3 (hMC3) receptor, displaying an IC50 value of 210 nM, while exhibiting negligible activity at the hMC4 receptors (EC50 = 9900 nM) and hMC5 receptor [1].

HS014 TFA, a potent and selective antagonist of the melanocortin-4 (MC4) receptor, exhibits K i values of 3.16, 108, 54.4, and 694 nM for the human MC4, MC1, MC3, and MC5 receptors, respectively. It effectively increases food intake in free-feeding rats [1] [2].

Adrenocorticotropic Hormone (ACTH) (1-39) human (TFA), a member of the melanocortin family, is a melanocortin receptor agonist that stimulates corticosteroid production by the adrenals; melanocortin receptors are also located in the central nervous system (CNS) and on immune cells.
