3,5-Bicyclic aryl piperidines: A novel class of α4β2 neuronal nicotinic receptor partial agonists for smoking cessation
摘要:
3,5-Bicyclic aryl piperidines are a new class of high-affinity alpha 4 beta 2 nicotinic receptor agents. We have sought nicotinic receptor partial agonists of the alpha 4 beta 2 nicotinic acetylcholine receptor for smoking cessation, and a number of compounds fulfill potency, selectivity, and efficacy requirements in vitro. In vivo, selected agents demonstrate potent partial agonist efficacy on the mesolimbic doparnine system, a key measure of therapeutic potential for smoking cessation. (c) 2005 Elsevier Ltd.
