2-(Aryloxymethyl)Azacyclic Analogues As Novel Nicotinic Acetylcholine Receptor (Nachr) Ligands

A series of 2-(aryloxymethyl) azetidine and pyrrolidine nAChR ligands in which the 3-pyridyl moiety of a previously described series(1) was replaced by a substituted phenyl group was explored. Aromatic substitution afforded analogues with K-i values ranging from 3 Co >10,000 nM. Generally, substitution at the ortho- and para-position was unfavorable, whereas electron-withdrawing groups at the meta-position improved the Ki values. Copyright (C) 1996 Elsevier Science Ltd
