CYTISINE Usage And Synthesis
  • DescriptionCytisine (also known as baptitoxine and sophorine) is a kind of naturally occurring alkaloid that can be found in several plant genera including Laburnum and Cytisus in the family Fabaceae. It has been shown that it is effective in the smoking cessation treatment. It is a low efficacy partial agonist of alpha4-beta2 nicotinic acetylcholine receptors, which is the central target of the nicotine that facilitates addiction. Cytisine is capable of reducing the effect of nicotine on dopamine release on the mesolimbic system as well as attenuating the nicotine withdrawal symptoms. Cytisine is also a useful reagent for organic chemistry such as being used for the manufacture of sparteine surrogate.
  • Biological FunctionsCytisine has a physiological action similar to that of nicotine. Poisoning in Europe is generally from laburnum trees (Laburnum anagyroides, Leguminosae), while, in the tropics and America, Sophora species (Leguminosae) are often the cause. The alkaloid occurs in all parts of laburnum, but is most concentrated in the seeds, which can be mistaken for peas by children. Cytisine does not always affect cattle, but this compound can be excreted in milk and so poison children.

  • UsesCytisine occurs in the seeds of Cytisus labur num L. and other Leguminosae.
  • DefinitionChEBI: An organic heterotricyclic compound that is the toxic principle in Laburnum seeds and is found in many members of the Fabaceae (legume, pea or bean) family. An acetylcholine agonist, it is widely used throughout Eastern Europe as n aid to giving up smoking.
  • Health HazardCytisine is highly toxic to humans and ani mals. Ingestions may cause nausea, vomiting,and convulsions. Death may occur from respiratory failure
    LD50 value, oral (rats): 101 mg/kg.
  • Biological ActivityA potent, selective agonist at neuronal nicotinic receptors. Acts as a partial agonist at β 2-containing nicotinic receptors.
  • Purification MethodsCrystallise cytisine from acetone and sublime it in a vacuum. Its solubilities are: 77% (H2O), 7.7% (Me2CO), 28.6% (EtOH), 3.3% (*C6H6), 50% (CHCl3) but it is insoluble in pet ether. The tartrate has m 206-207o [] D +45.9o, the N-tosylate has m 206-207o, and the N-acetate has m 208o. [Bohlmann et al.
