Exploration of the structure–activity relationship of the diaryl anilide class of ligands for translocator protein—potential novel positron emitting tomography imaging agents
摘要:
A series of novel ligands based on the diaryl anilide (DAA) class of translocator protein (TSPO) ligands was synthesised and evaluated as potential positron emitting tomography (PET) ligands for imaging TPSO in vivo. Fluorine-18 labelling of the molecules was achieved using direct radiolabelling or synthon based labelling approaches. Several of the ligands prepared have promising profiles as potential TSPO PET imaging ligands and will be evaluated further as potential clinical imaging agents. (C) 2012 Elsevier Ltd.

The present invention provides a novel radiolabeled aryloxyalinine derivative suitable for in vivo imaging. In comparison to known aryloxyalinine derivative in vivo imaging agents, the in vivo imaging agent of the present invention has better properties for in vivo imaging. The in vivo imaging agent of the present invention demonstrates good selective binding to the peripheral benzodiazepine receptor (PBR), in combination with good brain uptake and in vivo kinetics following administration to a subject.
