Background

Pozanicline dihydrochloride (ABT-089 dihydrochloride) is an orally bioavailable nicotinic acetylcholine receptor (nAChR) agonist with a Ki of 16.7 nM for binding to [3H]cytisine sites[1]. Pozanicline is an α4β2-selective nAChR agonist, which binds to rat brain α4β2 nAChR with a Ki of 17 nM while binding to α7 nAChR is insignificant[2].

Pozanicline (ABT-089) is a partial agonist at α4β2 nAChR. Moreover, one α6β2 nAChR subtype is particularly sensitive to Pozanicline with an EC50 of 0.11 μM[2]. Pozanicline (ABT-089) shows high selectivity for α6β2 and α4α5β2 nAChR subtypes[3].

Pozanicline (ABT-089; 0.3 mg/kg and 0.6 mg/kg) reverses nicotine withdrawal-induced deficits in contextual fear conditioning[3]. Animal Model: Adult male C57BL6/J mice at 8-12 weeks of age[3].
