Setmelanotide (BIM-22493) is a selective agonist of melanocortin 4 receptor (MC4R)(human and rat MC4R with EC50s of 0.27 nM and 0.28 nM, respectively).

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).

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.

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

Agouti-related Protein (AGRP) (83-132) Amide (human) is a segment derived from the agouti-related protein (AGRP), abundantly present in the hypothalamus' arcuate nucleus, and functions predominantly as an inverse agonist for the melanocortin-4 receptor (MC4R), thereby promoting food intake [1] [2].

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].

TCMCB07, a cyclic nonapeptide, serves as an orally active, brain-penetrant antagonist of the melanocortin receptor 4 (MC4R), with significant implications in the management of cachexia [1].

TCMCB07 acetate(1456699-27-6 Free base), a cyclic nonapeptide peptide, is an orally active and brain-penetrant melanocortin receptor 4 (MC4R) antagonist. TCMCB07 TFA plays an important role in cachexia.
