  摘要：

  本发明涉及氟代苯并噻唑衍生物，其制备方法以及利用该衍生物诊断阿尔茨海默病的成像剂，更具体地涉及化学式1所代表的氟代苯并噻唑衍生物，化学式2的衍生物作为其制备的起始材料，其制备方法，以及利用具有强结合力与β-淀粉样斑块（阿尔茨海默病的一种生物标志物）的氟代苯并噻唑衍生物诊断阿尔茨海默病的成像剂。根据本发明，通过简单的方法可获得传统方法难以合成的氟标记的苯并噻唑衍生物，所获得的苯并噻唑衍生物可用于诊断阿尔茨海默病的存在和严重程度。

  The present invention relates to fluorinated benzothiazole derivatives, a preparation method thereof, and an imaging agent for diagnosing Alzheimer' s disease using the same, and more particularly to fluorinated benzothiazole derivatives represented by Chemical Formula 1, derivatives of Chemical Formula 2 as a starting material for preparation thereof, a preparation method thereof, and an imaging agent for diagnosing Alzheimer's disease using fluorinated benzothiazole derivatives with a strong binding force to beta-amyloid plaque, which is a kind of biomarker for Alzheimer's disease. According to the present invention, fluorine-labeled benzothiazole derivatives, which have been difficult to synthesize by conventional methods, may be obtained by simple processes and the thus-obtained benzothiazole derivatives may be useful in diagnosing the presence and severity of Alzheimer's disease.

  Copper-catalyzed one-pot three-component reactions of 2-iodoanilines, aldehydes, and NaSH·n H2O afford benzothiazoles in good yields. When CuCl was employed as a catalyst in the absence of a ligand, a variety of aromatic aldehydes and substituted 2-iodoanilines reacted with NaSH·n H2O to produce the corresponding 2-arylbenzothiazoles in 70–98 % yields. The copper catalyst plays a key role in C–S bond

  铜催化的 2-碘苯胺、醛和 NaSH·n H2O 的一锅三组分反应以良好的收率提供苯并噻唑。当在没有配体的情况下使用 CuCl 作为催化剂时，各种芳香醛和取代的 2-碘苯胺与 NaSH·n H2O 反应生成相应的 2-芳基苯并噻唑，产率为 70-98%。铜催化剂在 NaSH·n H2O 和由 2-碘苯胺和醛缩合形成的芳基碘之间形成 C-S 键中起关键作用。研究发现，NaSH·n H2O 在苯并噻唑的形成过程中起硫替代物和氧化剂的作用。

  [C-11]2-(4'-(Methylamino)phenyl)-6-hydroxybenzothiazole ([C-11]PIB) is a most potential PET tracer for detecting the beta-amyloid plaques in Alzheimer's disease. Here the syntheses of three fluorinated PIB, namely 2-(4'-(methylamino)phenyl)-6-fluoroethoxybenzothiazole (O-FEt-PIB), 2-(4'-(methylamino)phenyl)-6-fluoro-benzothiazole (F-N-Me) and 2-(4'-(dimethylamino)phenyl)-6-fluorobenzo-thiazole (F-N,N-Me), and the radiosynthesis of one corresponding F-18-labeled PIB compound, [F-18]O-FEt-PIB, as well as their in vitro/in vivo biological characters were reported. The structures of the products were confirmed by IR, H-1 NMR, EI/ESI-MS, elemental analysis and HRMS techniques. The radiolabeled product was characterized by radio-TLC and radio-HPLC and purified by semi-preparative radio-HPLC. The suitable biological characters showed these tracers were potential to be developed as probes for detecting beta-amyloid plaques in Alzheimer's disease. (c) 2007 Elsevier B.V. All rights reserved.
