(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.
JNJ-5207787 is a penetrates the blood-brain barrier neuropeptide Y Y2receptor (Y2) antagonist. It is >100-fold selective versus human Y1, Y4, and Y5 receptors. JNJ-5207787 suppresses the binding of peptide YY with pIC50s of 7.0 and 7.1 for the human Y2 r
Neuropeptide Y (NPY) (3-36) is a C-terminal fragment of NPY, a neuropeptide involved in controlling appetite, blood pressure, cardiac contractility, and intestinal secretion. NPY (3-36) is an endogenous peptide produced by cleavage of NPY by dipeptidyl peptidase 4 (DPP-4). It binds selectively to the NPY receptorY2 (Ki = 0.41 nM in CHP 234 cells) over the Y1 receptor, where it does not bind at concentrations up to 1 μM. NPY (3-36) (0.1 nM) increases migration of human umbilical vein endothelial cells (HUVECs) by 80% after 12 hours in an in vitro wound closure assay. NPY (3-36) corresponds to residues 3-36 of the human and rat protein sequence.
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
