Analogues of the potent nicotinic receptor agonist 3-(2-aminoethoxy)pyridine substituted at the 5' and 6'-positions of the pyridine ring were synthesized and tested in vitro for nicotinic receptor binding activity (displacement of [H-3](-)cytisine from whole rat brain synaptic membranes). The substituted analogues exhibited K-i values ranging from 0.076 to 319 nM compared to a K-i value of 26 nM for compound 1. Among the compounds tested, 5'-vinyl-6'-chloro substituted I was the most potent. (C) 2002 Elsevier Science Ltd. All rights reserved.
