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 substitu
tion afforded analogues with K-i values ranging from 3 Co >10,000 nM.
Generally, substitution at the ortho- and para-position was unfavorabl
e, whereas electron-withdrawing groups at the meta-position improved t
he Ki values. Copyright (C) 1996 Elsevier Science Ltd
