  A methodology for the efficient conversion of aromatic sulfonamides into their mono-nitro derivatives using tert-butyl nitrite is reported. The reaction exhibits a high degree of chemoselectivity for sulfonamide functionalized aryl systems, even in the presence of other sensitive or potentially reactive functionalities.

  of N2-substituted aza-2H-indazole derivatives as potential kinase inhibitors. Guided by a rational ligand alignment approach to qualify the so-far underrepresented aza-2H-indazole scaffold, indazoles were connected at the N2 position with a phenyl spacer and an arylsulfonamide or amide linkage. Initial profiling against a panel of 30 kinases confirmed the in silico predicted selectivity bias. A synthesized

  新型脚手架的更广泛和系统的应用常常因缺乏短而可靠的合成通道而受阻。我们研究了一种设计和合成一系列N2取代的aza-2H-吲唑衍生物作为潜在激酶抑制剂的新策略。在合理的配体比对方法的指导下，对迄今代表性不足的aza-2H-吲唑支架进行鉴定，将吲唑在N2位与苯基间隔基和芳基磺酰胺或酰胺键连接。针对30种激酶的初步分析证实了计算机预测的选择性偏倚。合成的52个不同的aza-2H-吲唑衍生物的聚焦文库显示出对SGK1，Tie2和SRC激酶的良好初始选择性抑制作用，最佳代表的IC50值在500 nm范围内。

  作者：Ulrich Kloeckner、Boris J. Nachtsheim

  DOI：10.1039/c4cc04738a

  日期：——

  An oxidative and acid-free method for the nitration of N-aryl sulfonamides has been developed using a combination of sodium nitrite as cheap and easy to handle NO2-source and the hypervalent iodine reagent PIFA as stoichiometric oxidant. Under very mild reaction conditions, the desired mononitrated aryl sulfonamides were isolated in up to 87% yield. This is the first example of an iodane-mediated oxidative nitration.

  Keap1–Nrf2 PPI inhibitors were dissected into 77 fragments in a fragment-based deconstruction reconstruction (FBDR) study and tested in four orthogonal assays. This gave 17 fragment hits of which six were shown by X-ray crystallography to bind in the Keap1 Kelch binding pocket. Two hits were merged into compound 8 with a 220–380-fold stronger affinity (Ki = 16 μM) relative to the parent fragments. Systematic

  靶向核因子类红细胞2相关因子2（Nrf2）和与Kelch样ECH相关蛋白1（Keap1）之间的蛋白相互作用是控制涉及氧化应激疾病的潜在治疗策略。在这里，在基于片段的解构重建（FBDR）研究中，将六类已知的小分子Keap1-Nrf2 PPI抑制剂分解为77个片段，并在四个正交试验中进行了测试。这给出了17个片段命中，其中X射线晶体学显示其中6个在Keap1 Kelch结合袋中结合。相对于亲本片段，两个命中片段以220-380倍的亲和力（K i = 16μM）被合并到化合物8中。系统优化产生了一些与K i有关的新颖类似物值0.04–0.5μM，通过X射线晶体学测定的结合模式，以及增强的微粒体稳定性。这证明了FBDR如何可用于发现新的片段片段，阐明重要的配体-蛋白质相互作用以及鉴定Keap1-Nrf2 PPI的新有效抑制剂。
