  Indol-2-yl ethanones as novel indoleamine 2,3-dioxygenase (IDO) inhibitors

  摘要：

  Indoleamine 2,3-dioxygenase (IDO) is a heme dioxygenase which has been shown to be involved in the pathological immune escape of diseases such as cancer. The synthesis and structure-activity relationships (SAR) of a novel series of IDO inhibitors based on the indol-2-yl ethanone scaffold is described. In vitro and in vivo biological activities have been evaluated, leading to compounds with IC50 values in the micromolar range in both tests. Introduction of small substituents in the 5- and 6-positions of the indole ring, indole N-methylation and variations of the aromatic side chain are all well tolerated. An iron coordinating group on the linker is a prerequisite for biological activity, thus corroborating the virtual screening results. (C) 2010 Elsevier Ltd. All rights reserved.

  efficient and practical system for inexpensive bromination and iodination of arenes as well as heteroarenes by using readily available dimethyl sulfoxide (DMSO) and HX (X = Br, I) reagents is reported. This mild oxidative system demonstrates a versatile protocol for the synthesis of aryl halides. HX (X = Br, I) are employed as halogenating reagents when combined with DMSO which participates in the present

  105 degrees C. Under these conditions an unprecedented reaction sequence occurs leading to condensed pyridones in 23-86% yield. The proposed pathway proceeds through palladacycle-catalyzed homocoupling of the bromoamide, followed by intramolecular carbon-nitrogen bond-forming reaction with the carbon atom bearing the aminocarbonyl group, which is easily eliminated under palladium catalysis.

  据报道，使用 Pd(OAc)2/TFP 作为催化剂，在 105 摄氏度的 DMF 中使用 K2CO3 作为碱，从邻溴芳族甲酰胺催化合成缩合吡啶酮。在这些条件下，发生了前所未有的反应序列，导致在 23 -86% 的收率。所提出的途径通过钯环催化的溴酰胺均偶联进行，然后与带有氨基羰基的碳原子发生分子内碳 - 氮键形成反应，在钯催化下很容易消除。
