MC1R Antagonists (4):

Cat. No. Product Name Effect Purity
  • HY-P0097A
    Nonapeptide-1 acetate salt
    		Antagonist 98.70%
    Nonapeptide-1 (Melanostatine-5) acetate salt, a peptide hormone, is a selective antagonist of MC1R (Ki: 40 nM). Nonapeptide-1 acetate salt is a competitive α-MSH antagonist that potently inhibits intracellular cAMP and melanosome dispersion induced by α-MSH in melanocytes (IC50: 2.5 nM and 11 nM, respectively). Nonapeptide-1 acetate salt inhibits melanin synthesis, and can be used in the research of skin pigmentation and regulation of steroid production in the adrenal gland, skin cancer.
  • HY-P99004
    hMC1R agonist 1
    		Antagonist
    (EC50=3 nM). hMC1R agonist 1 shows at least 300-fold selectivity for hMC1R over hMC3R (b>EC50=902 nM), hMC4R (b>EC50=915 nM), and hMC5R (b>EC50=>1000 nM). hMC1R agonist 1 has the potential for the therapeutic intervention of melanocortin family.

  • HY-P1726A
    MSG606 TFA
    		Antagonist
    MSG606 TFA is a potent human MC1 receptor antagonist (IC50=17 nM). MSG606 TFA also partial agonist at human MC3 and MC5 receptors (EC50 values are 59 and 1300 nM, respectively). MSG606 TFA exhibits binding affinity for A375 melanoma cells in vitro. MSG606 TFA reverses the induced hyperalgesia in female mice, with no effect in male mice.
