MC4R Antagonists (8):

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-P1215A
    HS024 TFA
    		Antagonist 99.80%
    HS024 is a selective MC4 receptor antagonist, with Kis of 0.29, 3.29, 5.45, 18.6 nM for MC4, MC5, MC3, and MC1, respectively. HS024 increase food intake.
  • HY-P1216A
    HS014 TFA
    		Antagonist 99.87%
    HS014 TFA is a potent and selective melanocortin-4 (MC4) receptor antagonist, with Kis of 3.16, 108, 54.4 and 694 nM for human MC4, MC1, MC3 and MC5 receptors respectively. HS014 TFA increases food intake in free-feeding rats.
  • HY-P1213
    JKC363
    		Antagonist 99.55%
    JKC363, a selective melanocortin MC4 receptor antagonist, has a 90-fold higher affinity at the MC4 receptor (IC50=0.5 nM) than at the MC3 receptor (44.9 nM). JKC-363 blocks the stimulatory effect of α-MSH on TRH release. Anti-hyperalgesic effect.
  • HY-P1216
    HS014
    		Antagonist
    HS014 is a potent and selective melanocortin-4 (MC4) receptor antagonist, with Kis of 3.16, 108, 54.4 and 694 nM for human MC4, MC1, MC3 and MC5 receptors, respectively. HS014 modulates the behavioral effects of morphine in mice. HS014 increases food intake in free-feeding rats.
  • HY-P3561
    Agouti-related Protein (AGRP) (83-132) Amide (human)
    		Antagonist
    Agouti-related Protein (AGRP) (83-132) Amide (human) is a fragment of agouti-related protein (AGRP) which is a protein found in abundance in the arcuate nucleus of the hypothalamus. AgRP primarily acts as an inverse agonist for the melanocortin-4 receptor (MC4R) to increase food intake.
  • HY-P0097
