  Synthesis and evaluation of pyridylbenzofuran, pyridylbenzothiazole and pyridylbenzoxazole derivatives as 18F-PET imaging agents for β-amyloid plaques

  摘要：

  The synthesis and SAR of new beta-amyloid binding agents are reported. Evaluation of important properties for achieving good signal-to-background ratio is described. Compounds 27, 33, and 36 displayed desirable lipophilic and pharmacokinetic properties. Compound 27 was further evaluated with autoradiographic studies in vitro on human brain tissue and in vivo in Tg2576 mice. Compound 27 showed an increased signal-to-background ratio compared to flutemetamol 4, indicating its suitability as PET ligand for b-amyloid deposits in AD patients. The preparation of the corresponding F-18-labeled PET radioligand of compound 27 is presented. (C) 2012 Elsevier Ltd. All rights reserved.
