Naturally occurring alkaloid (-)-cytisine 1 is an efficient acetylcholine agonist possessing a strong affinity to nicotinic acetylcholine receptors (nAChRs) . Owing to its biological activity (-)-cytisine has been used as an active ingredient of anti-smoking medications . Various chemical modifications of (-)-cytisine were applied to obtain novel bicyclic compounds for rational drug discovery . For example, N-alkylations , reductive aminations , nitrations, halogenations, alkylations, and arylations allowed to obtain numerous biologically active (-)-cytisine analogs. In search for innovative antiviral drugs, many compounds in which (-)-cytisine is attached to natural chromone  or coumarin  derivatives were prepared by aminomethylation  or alkylation  reactions. Additionally, the Diels-Alder reaction of N-alkyl and N-acyl derivatives of (-)-cytisine with N-substituted maleimides gave rise to several biologically potentcompounds .
In the given context, Life Chemicals offers various derivatives of (-)-cytisine, including those involving chromone, coumarin, and other heterocyclic substructures. These species can be considered both as building blocks and compounds for biological screening.
