Nifene is a high affinity, selective nicotinic α4β2* receptor partial agonist used in medical research for nicotinic acetylcholine receptors, usually in the form of nifene (18F)[1][2] as a positron emission tomography (PET) radiotracer.[3][4]

Nifene has been used to assess the efficacy of acetylcholinesterase inhibitors in animal models, because the neurotransmitter acetylcholine competes with the binding of nifene at the nicotinic receptor site.[5][6] Learning and behavior studies in animal models using nifene have suggested a potential role of the nicotinic receptors located in distinct white matter tracts.[7] Nifene studies in animal models of lung cancer have suggested an upregulation of the nicotinic receptor in the lung tumors.[8][9] Novel PET and SPECT imaging agents as potential receptor antagonists have been developed based on the structure of nifene; niodene for SPECT,[10] nifrolene for PET [11] and niofene for PET/SPECT.[12] These new derivatives take advantage of the unique in vivo imaging properties of nifene.[13] Human studies with (18F)-nifene make it a promising nicotinic α4β2* receptor PET radiotracer for scientific research and has exhibited reliable test-retest reproducibility.[14] Human white matter thalamic radiations (or tracts) were well demarcated and quantified using (18F)-nifene.[15]
