ABSTRACT
ABT‐089 [2‐methyl‐3‐(2‐(S)‐pyrrolidinylmethoxy)pyridine dihydrochloride salt] is a selective neuronal nicotinic receptor (NNR) modulator with cognitive enhancing properties in animal models of cognitive functioning. Amongst NNR subtypes, ABT‐089 shows selectivity for the cytisine binding site on the α4β2 receptor subtype as compared to the α‐bungarotoxin (α‐BgT) binding sites on the α7 and α1β1δγ receptor subtypes. In functional in vitro electrophysiological and cation flux assays, ABT‐089 displays differential activity including agonism, partial agonism and antagonism depending upon the NNR subtype and assay. ABT‐089 is as potent and efficacious as (–)‐nicotine at evoking acetylcholine (ACh) release from hippocampal synaptosomes. Furthermore, ABT‐089 is neuroprotective against excitotoxic glutamate insults, with even greater potency seen after chronic treatment. Similarly, ABT‐089 is effective in models of cognitive functioning, including enhancement of baseline functioning as well as improvement of impaired cognitive functioning seen following septal lesioning and natural aging. In neuroprotective assays the compound is most potent by chronic administration. In stark contrast to the positive effects in the cognitive models, ABT‐089 shows little propensity to induce adverse
