✦ Synopsis
In an attempt to develop more selective muscarinic acetylcholine receptor (m-AcChR) antagonists, (R)-1-azabicyclo[2.2.2]oct-3-yl-thioxanthene-9-carboxylate, (R,S)-thiochromane-4-carboxylate, and (R,S)-chromane-4-carboxylate were synthesized. Evaluation of the binding affinities of these compounds to muscarinic receptors indicates that replacing the oxygen by sulfur in the xanthenyl and chromanyl moieties does not significantly change selectivity, but does reduce the affinity of 5 and enhance the affinity of 9a.
