(S)-5-Iodo-2, 3-dimethoxy-N-(1-azabicyclo [2.2. 2] oct-3-yl) benzamide (MIZAC) was prepared from 5-iodo-2, 3-dimethoxybenzoyl chloride and (S)-3-aminoquinuclidine.[125I] Iodode-stannylation of its corresponding 5-tri-n-butyltin derivative gave [125I]-MIZAC at 1800 Ci/mmol. Binding of [125I]-MIZAC in rat entorhinal cortex revealed a KD of 1.37±0.21 nM. A series of racemic 2-O-alkyl derivatives of MIZAC were prepared and 5-HT-3 receptor ...
