Abstract
Selective and potent cholinergic ligands selective for neuronal nicotinic cholinergic channel receptors, which ligands have the formula: ##STR1## as well as pharmaceutically-acceptable salts or prodrugs thereof, which are useful in the treatment of dementias, attentional hyperactivity disorder, or substance abuse withdrawal characterized by decreased cholinergic function, one of which is also an analgesic agent, and one of which is an agent useful for treating anxiety associated with cognitive impairment.
Claims3
