Lys-Pro-Val · α-MSH C-terminal tripeptide

KPV is a tripeptide derived from the C-terminal sequence of alpha-melanocyte-stimulating hormone (α-MSH). It exhibits potent anti-inflammatory effects by inhibiting NF-κB signaling and proinflammatory cytokine production. Research is particularly focused on its potential for inflammatory bowel disease, colitis, and skin inflammation, with studies showing efficacy even when administered orally or topically.

Alpha-Melanocyte-Stimulating Hormone · α-Melanotropin

α-MSH is an endogenous 13-amino-acid peptide derived from POMC (pro-opiomelanocortin). It activates MC1R to stimulate melanin production in skin, MC4R to suppress appetite and regulate energy expenditure, and MC3R/MC1R to exert potent anti-inflammatory effects. It is the parent compound from which many synthetic melanocortin analogs (Melanotan I, II, PT-141, KPV) were derived and remains a cornerstone of melanocortin pharmacology research.
