  Biochemical and Structural Evaluation of Highly Selective 2-Arylbenzoxazole-Based Transthyretin Amyloidogenesis Inhibitors

  摘要：

  To develop potent transthyretin (TTR) amyloidogenesis inhibitors that also display high binding selectivity in blood, it proves useful to systematically optimize each of the three substructural elements that comprise a typical inhibitor: the two aryl rings and the linker joining them. In the first study, described herein, structural modifications to one aryl ring were evaluated by screening a library of 2-arylbenzoxazoles bearing thyroid hormone-like aryl substituents on the 2-aryl ring. Several potent and highly selective amyloidogenesis inhibitors were identified that exhibit minimal thyroid hormone nuclear receptor and COX-1 binding. High resolution crystal structures (1.3-1.5 angstrom) of three inhibitors (2f, 4f, and 4d) in complex with TTR were obtained to characterize their binding orientation. Collectively, the results demonstrate that thyroid hormone-like substitution patterns on one aryl ring lead to potent and highly selective TTR amyloidogenesis inhibitors that lack undesirable thyroid hormone receptor or COX-1 binding.

• Palladium-Catalyzed Direct Arylations of Heteroarenes with Tosylates and Mesylates
  作者：Lutz Ackermann、Andreas Althammer、Sabine Fenner

  DOI：10.1002/anie.200804517

  日期：2009.1

  A toss up: A highly active palladium complex enabled the first direct arylation of heteroarenes through CH bond functionalization using tosylates or mesylates as electrophiles with ample scope.

  抛弃：高活性的钯络合物可以使用甲苯磺酸盐或甲磺酸盐作为亲电试剂，通过CH键官能化，使杂芳烃首次直接芳基化，且具有足够的范围。
• An efficient magnetic copper ferrite nanoparticle: for one pot synthesis of 2-substituted benzoxazole via redox reactions
  作者：Sachin A. Sarode、Jeevan M. Bhojane、Jayashree M. Nagarkar

  DOI：10.1016/j.tetlet.2014.11.065

  日期：2015.1

  A new, green and sustainable approach for the synthesis of 2-substituted benzoxazole by using a one pot redox cascade condensation reaction of benzyl amine and 2-nitro phenol, catalysed by Cu Ferrite NPs is reported. Cu Ferrite NPs are magnetically separable, air stable and can be recycled up to fifth cycle without a significant loss in catalytic activity. The catalyst is characterised by FEG-SEM, TEM, EDAX and XRD. (C) 2014 Elsevier Ltd. All rights reserved.
• Sequential one-pot synthesis of benzoxazoles from aryl bromides: successive palladium- and copper-catalyzed reactions

  日期：2013.6

  A convenient one-pot process has been developed for the synthesis of benzoxazoles. Starting from aryl bromides and 1,2-dibromobenzenes palladium-catalyzed aminocarbonylation and subsequent copper-catalyzed coupling reaction gave a variety of substituted benzoxazoles in moderate to good yields.
