Compounds based on the 3-(dimethylamino)butyl dimethylcarbamate (DMABC) scaffold were synthesized and pharmacologically characterized at the alpha(4)beta(2), alpha(3)beta(4), alpha(4)beta(4) and alpha(7) neuronal nicotinic acetylcholine receptors (nAChRs). The carbamate functionality and a small hydrophobic substituent in the C-3 position were found to be vital for the binding affinity to the nAChRs, whereas the carbamate nitrogen substituents were important for nAChR subtype selectivity. Finally, the compounds were found to be agonists at the alpha(3)beta(4) nAChR. (C) 2008 Elsevier Ltd. All rights reserved.

structures of acetylcholinebinding proteins (AChBPs) have revealed two different possible extensions to the classical ligand binding pocket known to accommodate variousnicotinic agonists. One of the pockets is limited in size while the other is of considerable dimensions and protrudes along the interfacial cleft between subunits. To probe these putative extensions in functional nicotinicacetylcholine receptors
