| | MK 0557 Usage And Synthesis |
| Description | MK-0557 is a potent antagonist of the neuropeptide Y (NPY) receptor Y5 (Kis = 1.3, 0.79, 0.74, and 1.4 nM for human, rhesus monkey, mouse, and rat receptors, respectively). It is >7,500-fold selective for Y5 over other receptors and lacks activity in a panel of 180 receptors, enzymes, and ion channels at concentrations up to 1 μM. MK-0557 increases intracellular calcium in CHO cells expressing the human Y5 receptor in a concentration-dependent manner. In vivo, MK-0557 (30 mg/kg) reduces body weight gain in wild-type and diet-induced obese mice. It also reduces retroperitoneal fat pad weight, epididymal and mesenteric fat pad weights, leptin levels, and food intake in lean mice fed a high-fat diet. | | Uses | MK-0557 is a highly selective, orally available neuropeptide Y5 receptor antagonist with a Ki of 1.6 nM. | | 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[2]. | | IC 50 | NPY Y5 receptor | | References | [1] Fichtner M, et al. Discovery and evaluation of spirocyclic derivatives as antagonists of the neuropeptide Y5 receptor. Bioorg Med Chem Lett. 2012 Apr 15;22(8):2738-43. DOI:10.1016/j.bmcl.2012.02.098
