Cat. No. 5954
Biological ActivityPotent human MC1 receptor antagonist (IC50 = 17 nM). Also partial agonist at human MC3 and MC5 receptors (EC50 values are 59 and 1300 nM, respectively). Exhibits binding affinity for A375 melanoma cells in vitro. Reverses morphine-induced hyperalgesia in female mice, with no effect in male mice. γMSH analog.
(Modifications: X = Butanoic acid, Gly-11 = C-terminal amide, Phe-4 = D-Phe, Trp-6 = D-Trp, carba sulfide bridge between X-1 - Cys-7)
