  Diaryl hydroxylamines as pan or dual inhibitors of indoleamine 2,3-dioxygenase-1, indoleamine 2,3-dioxygenase-2 and tryptophan dioxygenase

  摘要：

  Tryptophan (Trp) catabolizing enzymes play an important and complex role in the development of cancer. Significant evidence implicates them in a range of inflammatory and immunosuppressive activities. Whereas inhibitors of indoleamine 2,3-dioxygenase-1 (IDO1) have been reported and analyzed in the clinic, fewer inhibitors have been described for tryptophan dioxygenase (TDO) and indoleamine 2,3-dioxygenase-2 (IDO2) which also have been implicated more recently in cancer, inflammation and immune control. Consequently the development of dual or pan inhibitors of these Trp catabolizing enzymes may represent a therapeutically important area of research. This is the first report to describe the development of dual and pan inhibitors of IDO1, TDO and IDO2. (C) 2018 Elsevier Masson SAS. All rights reserved.

• Waste-Free Swift Synthesis of Symmetrical and Unsymmetrical Diarylmethyl Thioethers from Diaryl Carbinols
  作者：Rama Peddinti、Pallavi Singh

  日期：2017.8

  to synthesize symmetrical and unsymmetrical diarylmethyl thioethers from diaryl carbinols and thiols in good to quantitative yields is reported. The thiol scope included alkyl and aryl thiols bearing electron-donating and electron-withdrawing groups. Short reaction time, high atom economy, inexpensive activator, free from workup and aryl halides, and gram-scale synthesis are the significant features

  compounds were devoid of any antimicrobial activity, but several of them inhibited T. rubrum with MIC values in the range of 0.125 to 32 µg/mL, similar or superior to those of bifonazole and clotrimazole, used as standard controls. The replacement of the imidazole ring with a triazole moiety in these compounds led to derivatives with less antifungal activity. A preliminary SAR was undertaken on the effect

  合成了两个系列的氯化二苯甲基咪唑和三唑衍生物，并针对强致病菌的代表性菌株（金黄色葡萄球菌 CIP 4.83、伊氏埃希氏菌 CIP 5855、铜绿假单胞菌 CIP 82118、大肠杆菌CIP 和真菌 IP 53126）进行了体外测试白色念珠菌 IP 48.72、克柔念珠菌 IP 208.52、红色毛癣菌 IP 1657.86)。这些化合物中的大多数没有任何抗菌活性，但其中一些抑制红色毛癣菌的 MIC 值在 0.125 至 32 µg/mL 范围内，类似于或优于联苯苄唑和克霉唑，用作标准对照。在这些化合物中用三唑部分取代咪唑环导致抗真菌活性较低的衍生物。

  A novel ether/BF3 reductive system has been described, in which diphenylmethanols and their ether and ester derivatives are used as starting materials. Reductions are performed in ether under reflux and an argon atmosphere, and the addition of extra water is beneficial to this reduction. A series of alkanes are able to be prepared with good to excellent yields. A deuterated experiment exhibits that

  A novel and efficient allylic alkylation reaction between π-activated ethers and allylsilane was realized under mild conditions through iron(III)-catalyzed C–O ether bond cleavage. The present protocol provides an attractive approach for the construction of sp3–sp3 C–C bonds and can be potentially applied for the selective reduction of benzyl and allyl ethers to their corresponding hydrocarbon compounds
