Description: CGP71683 hydrochloride (CGP71683A) is a competitive neuropeptide Y5 receptor antagonist (Ki: 1.3 nM) and shows no obvious activity at Y1 receptor (Ki >4000 nM) and Y2 receptor (Ki: 200 nM) in cell membranes. Target: Neuropeptide Y Receptor. Smiles:...

CGP 71683 is an antagonist of neuropeptide Y (NPY) receptor Y5 (IC50 = 1.4 nM in a radioligand binding assay). It is selective for Y5 over Y1, Y2, and Y4 receptors (IC50s = 2,765, 7,187, and 5,637 nM, respectively). It inhibits NPY-induced increases in BT-549 cell growth and MDA-MB-231 cell migration when used at a...
