  Synthesis and Evaluation of ¹¹C-Labeled 6-Substituted 2-Arylbenzothiazoles as Amyloid Imaging Agents

  摘要：

  The synthesis and evaluation of a series of neutral analogues of thioflavin-T (termed BTA's) with high affinities for aggregated amyloid and a wide range of lipophilicities are reported. Radiolabeling with high specific activity [C-11]methyl iodide provided derivatives for in vivo evaluation. Brain entry in control mice and baboons was high for nearly all of the analogues at early times after injection, but the clearance rate of radioactivity from brain tissue varied by more than 1 order of magnitude. Upon the basis of its rapid clearance from normal mouse and baboon brain tissues, [N-methyl-C-11]2-(4'-methylaminophenyl)-6-hydroxybenzothiazole (or [C-11]6-OH-BTA-1) was selected as the lead compound for further evaluation. The radiolabeled metabolites of [C-11]6-OH-BTA-1 were polar and did not enter brain. The binding affinities of [N-methyl-H-3]6-OH-BTA-1 for homogenates of postmortem AD frontal cortex and synthetic Abeta(1-40) fibrils, were similar (K-d = 1.4 nM and 4.7 nM, respectively), but the ligand-to-Abeta peptide binding stoichiometry was similar to400-fold higher for AD brain than Abeta(1-40) fibrils. Staining of AD frontal cortex tissue sections with 6-OH-BTA-1 indicated the selective binding of the compound to amyloid plaques and cerebrovascular amyloid. The encouraging in vitro and in vivo properties of [C-11]6-OH-BTA-1 support the choice of this derivative for further evaluation in human subject studies of brain Abeta deposition.

  使用硅烷/氧-R配合物体系高度还原芳香硝基化合物的化学和区域选择性

  摘要：

  据报道，由高价氧-hen络合物催化的硅烷将芳族硝基化合物还原为相应的胺。PhMe 2 SiH / ReIO 2（PPh 3）2（5 mol％）和PhMe 2 SiH / ReOCl 3（PPh 3）2（5 mol％）催化体系在宽范围的存在下有效还原了一系列芳族硝基化合物官能团的范围，例如酯，卤素，酰胺，砜，内酯和苄基。该方法还允许在脂肪族硝基存在下将二硝基苯区域选择性还原成相应的硝基苯胺和将芳族硝基还原。

  The reduction of aromatic nitro compounds to the corresponding amines with silanes catalyzed by high valent oxo-rhenium complexes is reported. The catalytic systems PhMe2SiH/ReIO2(PPh3)2 (5 mol %) and PhMe2SiH/ReOCl3(PPh3)2 (5 mol %) reduced efficiently a series of aromatic nitro compounds in the presence of a wide range of functional groups such as ester, halo, amide, sulfone, lactone, and benzyl

  An interesting radical coupling reaction of aromatic aldehydes with isocyanides was disclosed for the synthesis of amides catalyzed by copper. According to the experimental results and mechanistic study, the isocyano group acted as an N1 synthon rather than exhibiting the carbene-like reactivity, exploiting a new reactivity profile of isocyanides.

  日期：——

  A novel imidazolium salt-supported Mukaiyama reagent (2-chloropyridinium salt) has been developed and explored as an efficient coupling agent for amide bond formation. The use of an ionic liquid-supported reagent enabled isolation of the amide products by simple extraction with organic solvents in high purity and avoiding column chromatography purification.

  A ‘catch-and-release’ assessment of immobilised triphenylphosphine (PS-PPh3) and 1-hydroxybenzotriazole (PS-HOBt) as facilitators of acylation-mediated amide couplings is described. Through evaluations of reaction temperatures, substrate stoichiometries, solvents, and flow rates, we report findings in favour of PS-HOBt over PS-PPh3.
