Abstract:
The development of β+ emitter tracers labelled with carbon-11 or fluorine-18 having optimal characteristics of affinity and selectivity for the phosphodiesterase 10 A protein has received considerable attention, due to the major implication of this enzyme in neurological and psychiatric disorders, such as Hungtington's disease, Parkinson's disease and schizophrenia. The ability to quantify PDE10 A availability in the human brain in vivo will thus aid understanding its role in neurodegenerative and neuropsychiatric pathophysiology as well as providing a valuable tool for drug development. This manuscript reviews the different compound series assessed to date as PET radioligand for the PDE10 A in human and their use to support the development programmes of novel drugs or to evaluate PDE10 A alterations in pathologies as Huntington`s, Parkinson`s Diseases and Schizophrenia.

Charge is an inherent property of the atomic particles that make up matter and is measured in units called coulombs (C). Matter is composed of atoms, each consisting of electrons, protons, and neutrons. Electrons have a negative charge (-e), while protons...
