Alpha-MSH (α-Melanocyte-Stimulating Hormone)
Alpha-MSH (α-Melanocyte-Stimulating Hormone) — A tridecapeptide derived from proopiomelanocortin (POMC) that activates melanocortin receptors, studied in pigmentation and inflammation research.
What Is Alpha-MSH?
Alpha-melanocyte-stimulating hormone (alpha-MSH) is a 13-amino acid peptide (Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2, MW: 1665 Da) derived from proopiomelanocortin (POMC). It is the endogenous agonist of melanocortin receptors MC1R-MC5R, regulating skin pigmentation, appetite, inflammation, and sexual function. Several research peptides are derived from alpha-MSH modifications.
Alpha-MSH Derived Peptides
- Melanotan II: Cyclic analog targeting MC1R/MC3R/MC4R for pigmentation and sexual function
- PT-141 (Bremelanotide): MC4R-selective analog, FDA-approved for hypoactive sexual desire disorder
- KPV: C-terminal tripeptide (Lys-Pro-Val) retaining anti-inflammatory activity through NF-kB inhibition
- ACTH(1-24): N-terminal extension containing the alpha-MSH sequence, used diagnostically (Cosyntropin)
