A series of epibatidine analogs and their positional isomers bearing an 8-azabicyclo[3.2.1]octane moiety is described. Also some of their simplified analogs bearing a 3-piperidine moiety are reported. Their receptor binding profiles (5-HT1A, 5-HT1B, M1, M2, neuronal nicotinic receptor) and analgesic activity (hot plate, acetic acid induced writhing) have been studied. Some of the compounds, especially those containing an 8-azabicyclo[3.2.1]oct-2-ene moiety possess high afinity for the nicotinic cholinergic receptor. The most analgesically active compounds are also highly toxic. Optimized structures (PM3-MOPAC, Alchemy 2000, Tripos Inc.) of compounds 1-9 were compared with that of epibatidine.
