Application

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.

Biochem/physiol Actions

Potent agonist at α3β4 and α7 nicotinic acetylcholine receptors and partial agonist at α4β2 nicotinic acetylcholine receptors.

General description

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.

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.
