摘要：

Vortioxetine is a new multi-modal drug against major depressive disorder with high affinity for a range of different serotonergic targets in the CNS. We report the C-11-labeling of vortioxetine with [C-11] MeI using a Suzuki-protocol that allows for the presence of an unprotected amine. Preliminary evaluation of [C-11] vortioxetine in a Danish Landrace pig showed rapid brain uptake and brain distribution in accordance with the pharmacological profile, all though an unexpected high binding in cerebellum was also observed. [C-11] vortioxetine displayed slow tracer kinetics with peak uptake after 60 min and with limited wash-out from the brain. Further studies are needed but this radioligand may prove to be a valuable tool in unraveling the clinical effects of vortioxetine. (C) 2014 Elsevier Ltd. All rights reserved.
