Description: ABT-089 is a selective neuronal nicotinic acetylcholine receptor (nAChR) modulator (partial agonist) with cognitive enhancing properties. Amongst NNR subtypes, ABT-089 shows selectivity for the cytisine binding site on the alpha4beta2 receptor subtype as compared to the alpha-bungarotoxin (alpha-BgT) binding sites on the alpha7 and alpha1beta1deltagamma receptor subtypes. Studies have shown a reduced number of alpha4beta2 nAChRs in persons with dementia, suggesting the involvement of alpha4beta2 in cognition.
