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.
