  Preliminary evaluation of fluoro-pegylated benzyloxybenzenes for quantification of β-amyloid plaques by positron emission tomography

  摘要：

  A new series of fluoro-pegylated benzyloxybenzenes were designed, synthesized and evaluated as PET probes for early detection of A beta plaques. Molecular docking revealed that all of the flexible benzyloxybenzenes inserted themselves into the hydrophobic Va118_Phe20 cleft on the flat spine of the A beta fiber, in a manner similar to that of IMPY molecule. The most potent probe, [F-18]9a, exhibited a combination of high binding affinity to A beta aggregates (K-i= 21.0 +/- 4.9 nM), high initial brain uptake (9.14% ID/g at 2 min), fast clearance from normal brain tissue (1.79% ID/g at 60 min), and satisfactory in vivo biostability in the brain (95% of intact form at 2 min). [F-18]9a clearly labeled A beta plaques in in vitro autoradiography of postmortem AD patients and Tg mice brain sections. Ex vivo autoradiography further demonstrated that [F-18]9a did penetrate the intact BBB and specifically bind to A beta plaques in vivo. Overall, [F-18]9a may be a potential PET probe for imaging A beta plaques in AD brains. (C) 2015 Elsevier Masson SAS. All rights reserved.

  Parts of compounds, after being labeled by radionuclide, of the phenyl benzyl ether derivative, are used as Aβ plaque imaging agent. The structural formula of the phenyl benzyl ether derivative is shown by formula (I). The present invention develops a kind of brand new phenyl benzyl ether derivative which has high affinity with Aβ plaques in brains of AD patients. The chemical structure of the phenyl benzyl ether derivative is different from that of compounds disclosed in the prior art and the phenyl benzyl ether derivative belongs to a brand new compound for diagnosing and treating AD. The obtained Aβ plaque imaging agent has the advantages that the in-vivo stability is good, the fat solubility is low, the removal speed for the brain is fast, the problem of removing the radionuclide in vivo does not exist, and the application prospect and the market value are great.
