Background: Nicotine is a psychoactive drug presenting a diverse array of biological activities,
some positive, such as enhancement of cognitive performances, others negative, such as addiction
liability. Ligands that discriminate between the different isotypes of nicotinic acetylcholine
receptors (nAChRs) could present improved pharmacology and toxicity profile.
Results: Based on the recent crystal structure of a soluble acetylcholine binding protein from
snails, we have built atomic models of acetylcholine and nicotine bound to the pocket of four
