General description

Cytisine is an alkaloid present in Cytisus laburnum, particularly in its seeds. It might be effective for smoking cessation. Cytisine is a natural insecticide. It has a molecular structure similar to nicotine.[1] Cytisine may have antidepressant like properties.[2]

Biochem/physiol Actions

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

Features and Benefits

There are only 2 currently available radioligands, 2-(18)F-FA and 6-(18)F-FA, for quantitative PET of the main cerebral subtype of nicotinic acetylcholine receptors (α4β2-nAChRs) in humans. Both exhibit slow distribution kinetics in the brain and require several hours for PET imaging.

An important new area of antidepressant drug development involves targeting the nicotinic acetylcholine receptor (nAChR). This receptor, which is distributed widely in regions of the brain associated with depression, is also implicated in other important processes that are relevant to

The nicotine in tobacco is thought to modulate neuronal systems regulating mood. Moreover, it appears possible that blockade rather than activation of beta2-containing (beta2*) nicotinic acetylcholine receptors (nAChRs) may lead to antidepressant-like effects. We used cytisine, a partial agonist of
