alpha(3)beta(4), and alpha(7) neuronal nicotinic receptors. The 2'-phenyl derivative 3 shows no activity at these major receptor subtypes, while the 4'-phenyl analogue 4 shows an enhanced level of alpha(7) selectivity as compared to UB-165 and deschloro UB-165 2. These results are discussed within the context of recent pharmacophore models.
