• Copper-Catalyzed Decarboxylative CN Triple Bond Formation: Direct Synthesis of Benzonitriles from Phenylacetic Acids Under O₂Atmosphere
  作者：Qiang Feng、Qiuling Song

  DOI：10.1002/adsc.201301001

  日期：2014.5.26

  A copper‐catalyzed reaction of phenylacetic acids with urea was found to afford benzonitriles under an oxygen atmosphere. This reaction proceeds smoothly by a sequence of decarboxylation, dioxygen activation, CH bond functionalization, and nitrile formation with urea as the nitrogen source. Molecular oxygen was found to play a crucial role in this transformation. This reaction represents a novel protocol

• Design, synthesis and biological evaluation of indole-2-carboxylic acid derivatives as IDO1/TDO dual inhibitors

  日期：2020.2

  indole-2-carboxylic acid derivatives were synthesized, and their inhibitory activities against both enzymes along with structure-activity relationships were investigated. As a result, a number of 6-acetamido-indole-2-carboxylic acid derivatives were found to be potent dual inhibitors with IC50 values at low micromolar levels. Among them, compound 9o-1 was the most potent inhibitor with an IC50 value

  吲哚胺 2,3-双加氧酶 1 (IDO1) 和色氨酸 2,3-双加氧酶 (TDO) 参与色氨酸代谢的关键步骤，是肿瘤免疫治疗的潜在新靶点。在这项工作中，合成了多种吲哚-2-羧酸衍生物，并研究了它们对两种酶的抑制活性以及构效关系。结果，发现许多 6-乙酰氨基-吲哚-2-羧酸衍生物是有效的双重抑制剂，在低微摩尔水平下具有 IC50 值。其中，化合物9o-1是最有效的抑制剂，对IDO1的IC50值为1.17 μM，对TDO的IC50值为1.55 μM。此外，由化合物 9p 氧化产生的对苯醌衍生物 9p-O，还鉴定了它对两种酶的强烈抑制作用，IC50 值在两位数纳摩尔水平。使用分子对接和分子动力学模拟，我们预测了 IDO1 和 TDO 结合口袋内此类化合物的结合模式。该结果为进一步优化该系列 IDO1/TDO 双抑制剂的结构提供了见解。
