  SAR Studies on Tetrahydroisoquinoline Derivatives: The Role of Flexibility and Bioisosterism To Raise Potency and Selectivity toward P-glycoprotein

  摘要：

  The development of P-glycoprotein (P-gp) ligands remains of considerable interest, mostly for investigating the protein's structure and transport mechanism. In recent years, many different generations of ligands have been tested for their ability to modulate P-gp activity. The aim of the present work is to perform SAR studies on tetrahydroisoquinoline derivatives in order to design potent and selective P-gp ligands. For this purpose, the effect of bioisosteric replacement and the role of flexibility have been investigated, and four series of tetrahydroisoquinoline ligands have been developed: (a) 2-aryloxazole bioisosteres, (b) elongated analogues, (c) 2H-chromene, and (d) 2-biphenyl derivatives. The results showed that both 2-biphenyl derivative 20b and elongated derivative 6g behaved as strong P-gp substrates. In conclusion, important aspects for developing potent and selective P-gp ligands have been highlighted, providing a solid starting point for further optimization.

  通过定点碳碳胺化从烷基芳烃到苯胺

  摘要：

  苯胺是各种化学环境中的基本图案，并广泛用于精细化学品，聚合物，农用化学品和药物的工业生产中。苯胺合成的最新进展是在富电子芳烃中使用C–H键的伯胺化。但是，该策略有局限性：缺电子芳烃的胺化仍是一项艰巨的任务，而富电子芳烃的胺化对区域选择性的控制有限-形成间位胺化的产品特别困难。在这里，我们报告了一种简单易用的烷基芳烃或苄基醇的定点CC键伯胺，可直接有效地制备苯胺。该化学过程涉及新颖的C–C键转换，并为取代苯胺的合成提供了通用的协议。证明了使用O 2作为对环境有益的氧化剂，对模型化合物的研究表明该方法也可用于木质素的解聚。

  The photolyses of seven phenyl cation precursors in acetonitrile in the presence of anisole resulted in four distinct product patterns. These patterns are due to the chemoselective and regioselective chemistry of various phenyl cation isomers. This spin-selective chemistry provides a tool with which to fingerprint the singlet/triplet nature of any phenyl cation.(© Wiley-VCH Verlag GmbH & Co. KGaA,
