  Discovery and structure-activity relationship studies of 1-aryl-1H-naphtho[2,3-d][1,2,3]triazole-4,9-dione derivatives as potent dual inhibitors of indoleamine 2,3-dioxygenase 1 (IDO1) and trytophan 2,3-dioxygenase (TDO)

  摘要：

  Indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO), which mediate kynurenine pathway of tryptophan degradation, have emerged as potential new targets in immunotherapy for treatment of cancer because of their critical role in immunosuppression in the tumor microenvironment. In this investigation, we report the structural optimization and structure-activity relationship studies of 1-phenyl-1H-naphtho[2,3-d][1,2,3]triazole-4,9-dione derivatives as a new class of IDO1/TDO dual inhibitors. Among all the obtained dual inhibitors, 1-(3-chloro-4-fluorophenyl)-6-fluoro-1H-naphtho[2,3-d][1,2,3]triazole-4,9-dione (38) displayed the most potent IDO1 and TDO inhibitory activities with IC₅₀ (half-maximal inhibitory concentration) values of 5 nM for IDO1 and 4 nM for TDO. It turned out that compound 38 was not a PAINS compound. Compound 38 could efficiently inhibit the biofunction of IDO1 and TDO in intact cells. In LL2 (Lewis lung cancer) and Hepa1-6 (hepatic carcinoma) allograft mouse models, this compound also showed considerable in vivo anti-tumor activity and no obvious toxicity was observed. Therefore, 38 could be a good lead compound for cancer immunotherapy and deserving further investigation.

• Preparation of aromatic fluorides: facile photo-induced fluorinative decomposition of arenediazonium salts and their related compounds using pyridine–nHF

  pyridine–nHF solution, the photo-induced fluorinative decomposition of arenediazonium salts (ArN2BF4) (fluoro-dediazoniation) and the related compounds, such as quinonediazides and triazenes, has been successfully carried out to produce the corresponding aromatic fluorides (ArF) in good yields. The rate in the fluoro-dediazoniation of para-substituted ArN2BF4 in pyridine–nHF solution did not obey the classical

  通过使用吡啶-n HF溶液，已成功地进行了苯二氮杂鎓盐（ArN 2 BF 4）（氟脱重氮）和相关化合物（如醌二叠氮化物和三氮烯）的光致氟化分解，以生产相应的芳族氟化物（ArF）的高收益率。吡啶-n HF溶液中对位取代ArN 2 BF 4的氟脱氮反应速率不符合经典的Hammett方程，但与塔夫脱（Taft）的处理方法[双取代基参数关系（DSP）]很好地吻合。ArN 2 BF 4的热氟脱氮中反应速率受底物中取代基的影响很大。相反，仅观察到取代基对ArN 2 BF 4的光诱导的氟脱氮反应的速率有轻微的影响。
• Aqueous and Visible-Light-Promoted C–H (Hetero)arylation of Uracil Derivatives with Diazoniums

  Direct C5 (hetero)arylation of uracil and uridine substrates with (hetero)aryl diazonium salts under photoredox catalysis with blue light was reported. The coupling proceeds efficiently with diazonium salts and heterocycles in good functional group tolerance at room temperature in aqueous solution without transition-metal components. A plausible radical mechanism has been proposed.

  Alkyl N-aryl 1,2,3-triazole-carboxylates are important molecules or intermediates in medicinal chemistry, but the synthesis of N2-aryl counterparts remains elusive. Herein, we describe a Cu-mediated annulation reaction of alkyl 3-aminoacrylates with aryldiazonium salts, both of which are readily available substrates. Furthermore, alkyl 2-aminoacrylates are also viable substrates. Diverse alkyl N2-aryl

  N-芳基1,2,3-三唑-羧酸烷基酯是药物化学中的重要分子或中间体，但N2-芳基对应物的合成仍然难以捉摸。在本文中，我们描述了3-氨基丙烯酸烷基酯与芳基重氮盐的Cu介导的环化反应，这两种都是容易获得的底物。此外，2-氨基丙烯酸烷基酯也是可行的底物。N 2-芳基1,2,3-三唑-羧酸烷基酯及其类似物可以在温和的条件下快速制备。特别地，该方案允许人们访问碳酸酐酶抑制剂和塞来昔布的几种药物样变体。

  A simple and catalyst‐free strategy was developed for the synthesis of unsymmetrical thiosulfonates using readily available DABCO⋅(SO2)2 as a solid and bench‐stable sulfur dioxide surrogate. The corresponding thiosulfonates were obtained through a radical pathway with good functional group tolerance. This strategy offers a promising synthesis method for the construction of diverse and useful thiosulfonates
