Synthesis and evaluation of new hydrazide derivatives as neuropeptide Y Y5 receptor antagonists for the treatment of obesity
摘要:
NPY is the most potent orexigenic agent known to man, with NPY Y1 and NPY Y5 being the receptor subtypes that are most likely responsible for centrally-mediated NPY-induced feeding responses. Based on the aforementioned, novel hydrazide derivatives were prepared for the purpose of searching new NPY Y5 receptor antagonists. Many of the compounds exhibited nanomolar binding affinity for this receptor, affording trans-N-{4-[N'-(3,4-dichlorophenyl)hydrazinocarbonyl]cyclohexylmethyl}-4-fluorobenzenesulfonamide, which showed the best activity (IC50=0.43 nM).

Synthesis and evaluation of new arylsulfonamidomethylcyclohexyl derivatives as human neuropeptide Y Y5 receptor antagonists for the treatment of obesity
摘要:
NPY is the most potent orexigenic peptide identified up to now. Stimulation of food intake is measured by the Y-1 and Y-5 receptor subtypes. In this study, the synthesis and evaluation of new arylsulfonamidomethylcyclohexyl derivatives are described as potential selective antagonists of the human NPY Y-5 receptor. The SAR of these series was examined and the amide derivatives were the compounds that showed the best activities. trans-N-{4-[(Quinolin-3-yl)aminocarbonyl]cyclohexylmethyl}-2,4-dichlorobenzenesulfonamide (42) bound to the human neuropeptide Y Y-5 receptor with a 2 nM IC50.
