Two dimeric analogs of the muscarinic acetylcholine receptor (mAChR) agonist phenylpropargyloxy-1,2,5-thiadiazole-quinuclidine (NNC 11-1314) were synthesized and pharmacologically evaluated. In radioligand binding assays on Chinese hamster ovary (CHO) cell membranes expressing the individual human M(1) to M(5) mAChR subtypes, both dimers [(3S)-1,4-bis-(3-[(3-azabicyclo[2.2.2]octanyl)-1,2,5-thia...
