Brief DescriptionMK-0557 is a selective and orally available antagonist of the neuropeptide Y5 receptor (Ki: 1.6 nM).
-
DescriptionMK-0557 is a selective and orally available antagonist of the neuropeptide Y5 receptor (Ki: 1.6 nM).(In Vitro):Neuropeptide Y (NPY) is a potent orexigenic neuropeptide, and antagonism of NPY Y1 and NPY Y5 receptors (NPYxR) is considered a potentially important anti-obesity drug target. MK-0557 has a Ki=1.3 nM at the human NPY5R, with similar affinities at rhesus, mouse, and rat NPY5R. MK-0557 has no significant binding to the human NPY1R, NPY2R, NPY4R, or mouse NPY6R at concentrations of 10 μM.(In Vivo):MK-0557 antagonizes the effects of the NPY5R-selective agonist on body-weight gain and hyperphagia in C57BL/6J mice and significantly suppresses the body-weight gain in diet-induced obese (DIO) mice. When lean mice on regular chow are switched to a medium high-fat diet (4.2 kcal/g) and treated with MK-0557 at 30 mg/kg PO QD, MK-0557 causes a 40% reduction in body-weight gain at day 35.

GR 231118
Potent neuropeptide Y (NPY) Y1 receptor antagonist (pA2 = 10 and 10.5 at rY1 and hY1, receptors respectively). Also a potent and selective NPY Y4 receptor agonist (pEC50 values are 6.0, 8.6 and 6.1 for rY2, hY4 and rY5 receptors respectively). Suppresses food intake in rats in vivo. Also has affinity for neuropeptide FF (NPFF) receptors in vitro (Ki = 43-73 nM).
