A novel pyridine derivative, 3,5-bis-(1-methyl-pyrrolidin-2-yl)-pyridine, and a pair of diastereomers of 1,1'-dimethyl-[2,3']bipyrrolidinyl were isolated from the root of Nicotiana tabacum plants and identified as novel alkaloids by GC-MS analysis. The structures of these new alkaloids were confirmed by total synthesis. The affinities of these novel alkaloids, and other structurally related compounds for alpha4beta2*, alpha7* neuronal nicotinic acetylcholine receptors (nAChRs), and for nAChRs mediating nicotine-evoked dopamine release from rat striatum were also assessed. The results indicate that these compounds do not interact with alpha7* nAChRs, but inhibit [3H]nicotine binding to the alpha4beta2* nAChR subtype. The results also demonstrate that these compounds act as antagonists at nAChRs mediating nicotine-evoked dopamine release from rat striatum.
