Potent, selective peptide agonist for the neuropeptide Y Y5 receptor (IC50 values for inhibition of NPY binding to human Y5, Y1, Y2 and Y4 receptors are 0.24, 530, > 500, and 51 nM respectively, Ki at Y5 = 0.1 - 0.15 nM). Stimulates food intake in vivo.
(R)-JNJ-31020028 is a high-affinity, selective brain-penetrant antagonist of the neuropeptide Y Y2receptor, with pIC50 values of 8.07, 8.22, and 8.21 for human, rat, and mouse Y2receptors, respectively.
Neuropeptide Y (3-36) (human, rat) is a metabolite of neuropeptide Y (NPY) generated by dipeptidyl peptidase-4 (DPP4). Known as a selective Y2receptor agonist, Neuropeptide Y (3-36) (human, rat) effectively reduces the release of norepinephrine via the Y2receptor[1][2].
Potent neuropeptide Y (NPY) Y5 receptor agonist (pEC50 values are 7.82, 6.28, 6.44 and > 6 at rat Y5, Y4, Y1 and Y2receptors respectively) that displays > 26-fold, > 1000-fold and > 1000-fold selectivity over Y1, Y2 and Y4 receptors respectively. Induces
Potent, selective and competitive nonpeptide antagonist for the neuropeptide Y Y2receptor (IC50 = 15 nM). Displays > 650-fold selectivity for NPY Y2 over Y1, Y4 and Y5 receptors. Active in vivo.
BIBP 3226 trifluoroacetate is a mixed non-peptide neuropeptide Y Y1(NPY Y1) and neuropeptide FF (NPFF) receptor antagonist (Kivalues are 1.1, 79, 108, > 1000, > 1000 and >1000 for rNPY Y1, hNPFF2, rNPFF, rNPY Y2, rNPY Y4and rNPY Y5respectively). Produces an anxiogenic-like effect in rats following i.c.v. administration.
