Provided are bis-quaternary ammonium cyclophane compounds which are modulators of nicotinic acetylcholine receptors. Also provided are methods of using the compounds for modulating the function of a nicotinic acetylcholine receptor, and for the prevention and/or treatment of central nervous system disorders, substance use and/or abuse, and or gastrointestinal tract disorders.

A series of bis-pyridinium cyclophane analogs designed as conformationally restricted bis-quaternary ammonium compounds were evaluated for their affinity for the blood-brain barrier (BBB) choline transporter. All the cyclophanes investigated exhibited high affinity compared to choline. Of these compounds, N, N'-(1,10-decanediyl)3,3'-(1,9-decadiyn-1,10-diyl)-bis-pyridinium diiodide (5c) and N, N'-(1,9-nonanediyl) 3,3'-(1,9-decadiyn-1,10-diyl)-bis-pyridinium dibromide (5b) exhibited highest affinity with K(i) values of 0.8 mu M and 1.4 mu M, respectively, and constitute some of the most potent BBB choline transporter ligands reported.
