  Multidentate ¹⁸F-Polypegylated Styrylpyridines As Imaging Agents for Aβ Plaques in Cerebral Amyloid Angiopathy (CAA)

  摘要：

  beta-Amyloid plaques (A beta plaques) in the brain are associated with cerebral amyloid angiopathy (CAA). Imaging agents that could target the A beta plaques in the living human brain would be potentially valuable as biomarkers in patients with CAA. A new series of F-18 styrylpyridine derivatives with high molecular weights for selectively targeting A beta plaques in the blood vessels of the brain but excluded from the brain parenchyma is reported. The styrylpyridine derivatives, 8a-c, display high binding affinities and specificity to A beta plaques (K-i = 2.87, 3.24, and 7.71 nM, respectively). In vitro autoradiography of [F-18]8a shows labeling of beta-amyloid plaques associated with blood vessel walls in human brain sections of subjects with CAA and also in the tissue of AD brain sections. The results suggest that [F-18]8a may be a useful PET imaging agent for selectively detecting A beta plaques associated with cerebral vessels in the living human brain.
