Potent, selective peptide agonist for the neuropeptide Y Y5receptor (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.
Potent neuropeptide Y (NPY) Y5receptor agonist (pEC50 values are 7.82, 6.28, 6.44 and > 6 at rat Y5, Y4, Y1 and Y2 receptors 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 Y2 receptor (IC50 = 15 nM). Displays > 650-fold selectivity for NPY Y2 over Y1, Y4 and Y5receptors. Active in vivo.
