3-Bromocytisine is a derivative of the toxic alkaloid cytisine that acts as a highly potent agonist at neural nicotinic acetylcholine receptors , binding primarily to the α4 β2 and α7 subtypes . 3-Bromocytisine is a full agonist at the α7 subtype while it is only a partial agonist at α4 β2 , but has an extremely strong binding affinity at α4 β2 with 200-fold selectivity for α4 β2 over α7 . In animal studies 3-bromocytisine stimulates the release of dopamine and noradrenaline and increases locomotor activity .[ 1] [ 2] [ 3] [ 4]
