Description
Cytisine is an alkaloid originally found in Laburnum, Cytisus, and other Fabaceae-family plants. Cytisine exhibits antidepressant activity in vivo and activates nicotinic acetylcholine receptors (nAChRs), acting as a partial agonist at α4β2 nAChRs and a full agonist at α3β4 nAChRs. Cytisine is structurally similar to nicotine and shows some clinical benefit in increasing smoking cessation rates.
