Page/Page column 68, (2011/12/04)
The invention provides hydroxybupropion analogues capable of inhibiting the reuptake of one or more monoamines and/or acting as antagonists at nicotinic acetylcholine receptors. The compounds may selectively bind to one or more monoamine transporters, including those for dopamine, norepinephrine, and serotonin and/or may selectively bind to one or more nicotinic acetylcholine receptor subtypes. Such compounds may be used to treat conditions that are responsive to modification of monoamine levels and/or antagonism of nicotinic acetylcholine receptors, including drug dependency, depression, and obesity.

To create potentially superior aids to smoking cessation and/or antidepressants and to elucidate bupropions possible mechanisms of action(s), 23 analogues based on its active hydroxymetabolite (2S,3S)-4a were synthesized and tested for their abilities to inhibit monoamine uptake and nAChR subtype activities in vitro and acute effects of nicotine in vivo. The 3′,4′-dichlorophenyl [(±)-4n], naphthyl (4r), and 3-chlorophenyl or 3-propyl analogues 4s and 4t, respectively, had higher inhibitory potency and/or absolute selectivity than (2S,3S)-4a for inhibition of DA, NE, or 5HT uptake. The 3′-fluorophenyl, 3′-bromophenyl, and 4-biphenyl analogues 4c, 4d, and 4l, respectively, had higher potency for antagonism of α4β2-nAChR than (2S,3S)-4a. Several analogues also had higher potency than (2S,3S)-4a as antagonists of nicotine-mediated antinociception in the tail-flick assay. The results suggest that compounds acting via some combination of DA, NE, or 5HT inhibition and/or antagonism of α4β2-nAChR can potentially be new pharmacotherapeutics for treatment of nicotine dependence.
