3,5-Bicyclic aryl piperidines: a novel class of alpha4beta2 neuronal nicotinic receptor partial agonists for smoking cessation.

ABSTRACT

3,5-Bicyclic aryl piperidines are a new class of high-affinity alpha4beta2 nicotinic receptor agents. We have sought nicotinic receptor partial agonists of the alpha4beta2 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 dopamine system, a key measure of therapeutic potential for smoking cessation.
