Abstract
Serotonin and its various receptors are involved in numerous brain functions and neuropsychiatric disorders. The 5-HT1A family is the best characterized subtype of the fourteen currently known 5-HT receptors. The 5-HT1A receptor is closely involved in the pathogenesis of anxiety, depression, epilepsy and eating disorders and therefore is an important target for drug therapy. The development in the 1980s of molecules specifically targeting this receptor was followed by the rapid development of corresponding PET neuroimaging. Because this receptor represents a crucial target in neuroscience, a large number of radioligands have been developed by academic and industry centers for visualization and quantification, first in living animals and ultimately in humans. After a brief account of some of the structural and functional characteristics of brain 5-HT1A receptors, this review focuses on the main lines of evolutionopened up by preclinical and clinical 5-HT1A PET radiopharmaceuticals, illustrating the potential value of PET for clinical research and drug development.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
