UNLABELLED Serotonin 5-HT1A receptors have been implicated in disorders of the central nervous system and, therefore, are being studied by PET. Efforts are under way to improve in vivo stability of 5-HT1A agents currently in human use (11C-labeled N-(2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl-N-(2-pyridinyl)cyclohexanecarboxamide [11C-WAY-100635],(More)
Acetylcholinesterase inhibitors (AChEI's) are used to treat Alzheimer's disease (AD), and the putative mode of action is to increase acetylcholine (ACh) levels. Our goal is to evaluate competition of ACh with nicotinic alpha4beta2 receptor PET agonist radiotracer, 2-[(18)F]fluoro-3-[2-((S)-3-pyrrolinyl)methoxy]pyridine ((18)F-nifene). This ability to(More)
The alpha4beta2 nicotinic acetylcholine receptor (nAChR) has been implicated in various neurodegenerative diseases. Optimal positron emission tomography (PET) imaging agents are therefore highly desired for this receptor. We report here the development and initial evaluation of 2-fluoro-3-[2-((S)-3-pyrrolinyl)methoxy]pyridine (nifene). In vitro binding(More)
