Highly potent and selective small molecule neuropeptideYY2receptorantagonists are reported. The systematic SAR exploration of a hit molecule N-(4-ethoxyphenyl)-4-[hydroxy(diphenyl)methyl]piperidine-1-carbothioamide, identified from HTS, led to the discovery of highly potent NPY Y2antagonists 16 (CYM 9484) and 54 (CYM 9552) with IC50 values of 19 nM and 12 nM respectively.

A subject of the present Application is novel derivatives of benzimidazole and imidazopyridine which have a good affinity for certain sub-types of melanocortin receptors, in particular the MC4 receptors. They are particularly useful for treating pathological conditions and diseases in which one or more melanocortin receptors are involved. The invention also relates to pharmaceutical compositions containing said products.
A novel series of benzimidazoles was identified and optimized, leading to the discovery of potent and selective antagonists of the human melanocortin-4 receptor. In addition, compound 5i was shown to cross the blood-brain barrier after intravenous dosing in rats. (c) 2007 Elsevier Ltd. All rights reserved.
