3-bromocytisine 3-bromocytisine 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 α4β2 and α7 subtypes. 3-bromocytisine is a full agonist at the α7 subtype while it is only a partial agonist at α4β2, but has an extremely strong binding affinity at α4β2 with 200-fold selectivity for α4β2 over α7. in animal studies 3-bromocytisine stimulates the release of dopamine and noradrenaline and increases locomotor activity. 3-bromocytisineidentifiers iupac name (1r,5s)-9-bromo-1,2,3,4,5,6-hexahydro-1,5-methano-8h-pyridodiazocin-8-one cas number207390-14-5 ypubchem cid15519735chemspider21376088uniipl64c996qachemical and physical dataformulac11h13brn2omolar mass269.142 g·mol−13d model (jsmol)interactive image smiles c1cc2n(c(=o)c1br)c3c2cnc3 inchi inchi=1s/c11h13brn2o/c12-9-1-2-10-8-3-7(4-13-5-8)6-14(10)11(9)15/h1-2,7-8,13h,3-6h2/t7-,8+/m0/s1key:dwdclehdnicbmi-jgvffnpusa-n
