  芳族酮的钯催化分子间定向C-H酰胺化

  摘要：

  已经完成了 Pd 催化的芳香酮与磺酰胺和酰胺的定向邻位 CH 酰胺化。使用缺电子的 Pd 复合物 Pd(OTf)(2) 对这种转变的成功至关重要。该反应的一些关键中间体，即酮的环钯化配合物，已通过 X 射线晶体学表征。这些钯环的实验分析以及 N-甲基磺酰胺的实验结果表明，新反应似乎没有通过氮烯中间体进行。新开发的反应可用于合成有用的有机中间体，例如 2- 和 3- 烷基吲哚和 2- 氨基苯基酮。

  4-Substituted-2,3,5,6-tetrafluorobenzenesulfonamides as inhibitors of carbonic anhydrases I, II, VII, XII, and XIII

  摘要：

  A series of 4-substituted-2,3,5,6-tetrafluorobenezenesulfonamides were synthesized and their binding potencies as inhibitors of recombinant human carbonic anhydrase isozymes I, II, VII, XII, and XIII were determined by the thermal shift assay, isothermal titration calorimetry, and stop-flow CO2 hydration assay. All fluorinated benzenesulfonamides exhibited nanomolar binding potency toward tested CAs and fluorinated benzenesulfonamides posessed higher binding potency than non-fluorinated compounds. The crystal structures of 4-[(4,6-dimethylpyrimidin-2-yl)thio]-2,3,5,6-tetrafluorobenzenesulfonamide in complex with CA II and CA XII, and 2,3,5,6-tetrafluoro-4-[(2-hydroxyethyl)sulfonyl]benzenesulfonamide in complex with CA XIII were determined. The observed dissociation constants for several fluorinated compounds reached subnanomolar range for CA I isozyme. The affinity and the selectivity of the compounds towards tested isozymes are presented. (C) 2013 Elsevier Ltd. All rights reserved.

  over off‐target CA I and CA II. 3,4‐Disubstituted‐2,5,6‐trifluorobenzenesulfonamides bound CAs with higher affinity than 2,4‐disubstituted‐3,5,6‐trifluorobenzenesulfonamides. Many such fluorinated benzenesulfonamides were found to be nanomolar inhibitors of CA II, CA VII, tumor‐associated CA IX and CA XII, and CA XIII.

  设计，合成和评估了取代的三氟和四氟苯磺酰胺，作为高亲和力和同工型选择性碳酸酐酶（CA）抑制剂。通过荧光热移测定，等温滴定量热法和停止流动的CO 2来确定它们对重组人CA I，II，VA，VI，VII，XII和XIII催化域的结合亲和力水化测定。在2、3和4位上取代基的变化产生具有宽范围结合亲和力和同工型选择性的化合物。几种2,4-取代的-3,5,6-三氟苯磺酰胺是有效的CA XIII抑制剂，对脱靶CA I和CA II具有高选择性。3,4-二取代-2,5,6-三氟苯磺酰胺与CA的亲和力高于2,4-二取代-3,5,6-三氟苯磺酰胺。发现许多此类氟化苯磺酰胺是CA II，CA VII，与肿瘤相关的CA IX和CA XII和CA XIII的纳摩尔抑制剂。结合在几种CA同工型活性位点上的抑制剂的X射线晶体结构为抑制剂结合亲和力和选择性提供了结构-活性关系信息。
