3-pyr-Cytisine is a partial agonist of α4β2 receptor with Ki values of 0.91, 119 and 1100 nM for α4β2, α3β4 and α7 receptors, respectively . The alpha-4 beta-2 nicotinic receptor (α4β2 receptor) is a nicotinic acetylcholine receptor participated in learning and is widely expressed in the central nervous system. Also, α4β2 receptor has the highest affinity for nicotine. 3-pyr-Cytisine is an α4β2 receptor partial agonist. In cells expressed α4β2 receptor, 3-pyr-Cyt reduced the agonist response by ACh, which relayed on the intrinsic activity of 3-pyr-Cyt and 3-pyr-Cyt concentration . In PC12 cells, 3-pyr-Cyt significantly induced release of norepinephrine (NE) in a time-, dose- and Ca2+-dependent way. Also, 3-pyr-Cyt inhibited nicotine-induced NE release and increased the mRNA levels of tyrosine hydroxylase (TH), which is necessary for catecholamine biosynthetic . In the tail suspension test, mice treated with 3-pyr-Cyt (0.6 mg/kg) spent significantly less time immobile in a dose-dependent way. In the forced swim test, mice treated with 3-pyr-Cyt (0.3, 0.6 or 0.9 mg/kg) were significantly less immobile in a dose-dependent way, which suggested that 3-pyr-Cyt exhibited antidepressant-like effects in a dose-dependent way .
