Technetium-99m Labeled Pyridyl Benzofuran Derivatives as Single Photon Emission Computed Tomography Imaging Probes for β-Amyloid Plaques in Alzheimer’s Brains
Three novel99mTc-labeled pyridyl benzofuran derivatives were tested as potential probes for imaging β-amyloid plaques using singlephotonemissioncomputedtomography (SPECT). The 99mTc and corresponding rhenium complexes were synthesized with bis(aminoethanethiol) (BAT) as a chelating ligand. All Re complexes showed affinity for Aβ(1–42) aggregates (Ki = 13.6–149.6 nM).
