Radiolabeling of [ 11 C]FPS-ZM1, a Receptor for Advanced Glycation End products-targeting Positron Emission Tomography radiotracer, Using a [ 11 C]CO 2 -to-[ 11 C]CO Chemical Conversion

Abstract: Aim: The receptor for advanced glycation end products (RAGE) is a viable target for early Alzheimer’s disease (AD) diagnosis using positron emission tomography (PET) as RAGE overexpression precedes Aβ plaque formation. The development of a carbon-11 analog of FPS-ZM1 (N-benzyl-4-chloro-N-cyclohexylbenzamide, [11C]FPS-ZM1), possessing nanomolar affinity for RAGE, may enable the imaging of RAGE for early AD detection. Methodology & results: Herein we report an optimized [11C]CO2-to-[11C]CO chemical conversio… Show more

“…RAGE is expressed ubiquitously at low levels in the CNS, but, unlike MT 1 , RAGE expression is inducible by the level of inflammation in the microenvironment, and increases in the presence of RAGE ligands such as cytokines or other proinflammatory mediators [ 27 ]. For example, RAGE is documented to be overexpressed in hippocampal neurons in AD [ 9 ], consistent with the increased binding of [ 18 F]RAGER and [ 11 C]FPS-ZM1 in autoradiography studies with rodent and human AD brain tissue samples described above and previously reported [ 17 , 21 ]. Studies with [ 18 F]RAGER show the highest uptake in the thalamus and basal ganglia in healthy nonhuman primates, which may overlap with areas of MT 1 expression [ 17 ].…”

“…[ 19 , 20 ] and Luzi et al. [ 21 ] have reported autoradiography and rodent imaging with [ 18 F]RAGER and [ 11 C]FPS-ZM1, respectively. The in vivo imaging studies are all in agreement that despite high (96%) plasma protein binding ( Fig.…”

“…These tau and Aβ-targeting probes can also be used for quantification analysis to further validate the role of RAGE in the pathogenesis of AD (Fang et al, 2018). As RAGE overexpression precedes Aβ plaque formation (Luzi et al, 2020), [ 18 F]-FPS-ZM1 PET/CT imaging is expected to be more sensitive than traditional Aβ imaging. It can monitor changes in cerebrovascular function over time and thus provide accurate, reliable, and reproducible non-invasive in vivo quantitative data for local or whole-brain pathological changes.…”
