System xc- (Sxc -) has emerged as a new biological target for PET studies to detect oxidative and excitotoxic stress. Notably, applications have, thus far, been limited to tumour imaging although Sxc- ) may play a major role in neurodegeneration. The synthesis procedures of tosylate precursor and its translation to Sxc - PET tracer 5[18F]fluoro-L-amino suberate by manual and automated radiosyntheses are described. A brain-PET study has been conducted to evaluate the tracer uptake into brain in healthy mice.
Keywords: System xc; brain imaging; mouse; radiosynthesis.
