一般描述
Cystine ((1R,5S)-1,2,3,4,5,6-hexahydro-1,5-methano-8H-pyrido[1,2a][1,5]diazocin-8-one) displays classical antidepressant action in various animal models of antidepressant efficacy. Infrared and Raman spectral studies suggest that it has two stable conformers.
Cytisine was found to be more effective than nicotine-replacement therapy in helping smokers to quit smoking. It is an α4 β2 nicotinic receptor partial agonist. It is a plant alkaloid which is commercially extracted for use as a smoking cessation medication. Preparation of nicotine partial agonist cytisine via “in situ” Stille or Suzuki biaryl pyridine coupling has been reported. Cytisine is a competitive partial agonist at α4 subunit-containing nicotinic acetylcholine (nACh) receptors while at homomeric α7-nACh receptors it behaves as a full agonist with a relatively lower potency.
应用
Cystine may be used as nicotine substitute in nicotine addiction therapy.
Cytisine is suitable for use in a study to compare the effects of varenicline and cytisine on ethanol consumption by rats bred for many generations as high ethanol drinkers.

Neuronal nicotinic acetylcholine receptors (nAChRs) are pharmacological targets that have recently been implicated in the reinforcing effects of many drugs of abuse, including ethanol. Varenicline and cytisine are nAChR partial agonists in clinical use as smoking cessation aids. However, their
