  Isatin-pyrazole benzenesulfonamide hybrids potently inhibit tumor-associated carbonic anhydrase isoforms IX and XII

  摘要：

  New series of benzenesulfonamide derivatives incorporating pyrazole and isatin moieties were prepared using celecoxib as lead molecule. Biological evaluation of the target compounds was performed against the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1) and more precisely against the human isoforms hCA I, II (cytosolic), IX and XII (transmembrane, tumor-associated enzymes). Most of the tested compounds efficiently inhibited hCA I, II and IX, with K(1)s of 2.5-102 nM, being more effective than the reference drug acetazolamide. Compounds 11e, 11f, 16e and 16f were found to inhibit hCA XII with Ki of 3.7, 6.5, 5.4 and 7.2 nM, respectively. Compounds lie and 16e, with 5-NO2 substitution on the isatin ring, were found to be selective inhibitors of hCA IX and hCA XII. Docking studies revealed that the NO2 group of both compounds participate in interactions with Asp132 within the hCA IX active site, and with residues Lys67 and Asp130 in hCA XII, respectively.

  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。

  A new application of the hypervalent iodine reagent phenyliodine(III)bis(trifluoroacetate) (PIFA) has been developed for the construction of a series of N, O, S-containing heterocycle-fused quinolinone derivatives in a general and efficient way. An alternative approach to the formation of these novel tricyclic heterocycles by a PIFA mediated aryl–heteroaryl coupling reaction is also presented.
