Use of Cytisine

Cytisine is an alkaloid that occurs naturally in several plant genera, such as Laburnum and Cytisus. Cytisine is a partial agonist of α4β2 nAChRs[1], and partial to full agonist at β4 containing receptors and α7 receptors[2]. has been used medically to help with smoking cessation[3].

Description	Cytisine is an alkaloid that occurs naturally in several plant genera, such as Laburnum and Cytisus. Cytisine is a partial agonist of α4β2 nAChRs[1], and partial to full agonist at β4 containing receptors and α7 receptors[2]. has been used medically to help with smoking cessation[3].

Target	α4β2 nAChRs[1].
In Vitro	Cytisine (2.5, 5 and 10 mM) is capable of inducing apoptosis in HepG2 cells[4]. Treatment with Cytisine increases the percentage of cells in the sub-G1 phase (P<0.01). The preincubation of HepG2 cells with Cytisine (2.5, 5 and 10 mM) significantly increases the sub-G1 cell population[4].
In Vivo	Cytisine (5 mg/kg, i.p.) eat less and gain less weight than those that receive the vehicle[2]. Total pellet intake increases during Cytisine substitution relative to nicotine and animals self-administered Cytisine significantly less than nicotine[2].
