  4-Substituted 1,5-diarylpyrazole, analogues of celecoxib: synthesis and preliminary evaluation of biological properties

  摘要：

  A number of 5-aryl-1-[4-(methylsulfonyl)-phenyl]-1H-pyrazoles and 4-(5-aryl-1H-pyrazol-1-yl)benzenesulfonamides 3, 4, 5, 6, analogues of the COX-2 selective inhibitor celecoxib (celebrex), were synthesized. In order to verify the effects on the biological properties of certain substituents put on position 4 of the pyrazole nucleus, some of these compounds were screened in vivo for their anti-inflammatory and analgesic activities. Moreover, sodium salts of carboxylic acids 4 were tested in vitro for their platelet anti-aggregating properties. The results of these preliminary biological assays showed that new derivatives are not endowed with improved anti-inflammatory and analgesic properties, in comparison with celecoxib. In addition, docking studies were carried out on the most significative compounds to evaluate their interaction mode at the active site of both COX-1 and COX-2. Some remarks about the SAR of this class of COX-inhibitors are drown out.

  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。

  4-dichlorophenyl)-5-arylpyrazoles strictly related to rimonabant, but with the hydrazide/amide group shifted from position 3 to position 4 of the pyrazole scaffold. The synthesized compounds were evaluated in vitro for their affinity on human CB(1) and CB(2) (cannabinoid type-2) receptors. Computational studies, performed both in the design step and after biological assays, contributed to rationalize the obtained
