2-(Arylmethyl)-3-substituted quinuclidines as selective alpha 7 nicotinic receptor ligands.

A series of 2-(arylmethyl)-3-substituted quinuclidines was developed as alpha7 neuronal nicotinic acetylcholine receptor (nAChR) agonists based on a putative pharmacophore model. The series is highly selective for the alpha7 over other nAChRs (e.g.
