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.

Lys-γ3-MSH(human) TFA, a melanocortin peptide originating from the C-terminal fragment of pro-opiomelanocortin (POMC), enhances the steroidogenic response of rat adrenal glands to adrenocorticotrophin (ACTH). It is a potent stimulator of lipolysis, demonstrating an apparent EC50 of 3.56 nM, by activating hormone-sensitive lipase (HSL) and Perilipin A, leading to lipolysis [1] [2].

γ1-MSH TFA, a melanocortin MC3 receptor agonist, demonstrates a binding affinity (K i) of 34 nM for the rat MC3 receptor. Notably, it exhibits approximately 40-fold greater selectivity for the MC3 receptor compared to the MC4 receptor, with a K i of 1318 nM for MC4 [1].

[D-Trp8]-γ-MSH TFA is a potent, selective agonist for the melanocortin 3 (MC3) receptor, with IC50 values of 6.7 nM for hMC3, 600 nM for hMC4, and 340 nM for hMC5 in CHO cells. It shows potential for providing protection against various inflammatory disorders, including rheumatoid arthritis and colitis [1] [2].
