  三唑基和相关杂芳基取代基对 SNAr 反应的加速作用：氢键稳定过渡态的证据

  摘要：

  通过系统实验和密度泛函理论计算研究了 1,2,3-三唑基取代基对 SNAr 反应的显着加速作用。邻三唑基取代基的孤对电子通过与处于加成过渡态的胺亲核试剂形成优先氢键，在降低亲核加成的活化能方面发挥关键作用。在这一发现的扩展中，还发现了一系列具有相似电子对供体特性的相关杂芳基促进 SNAr 反应。实验确定的溶剂效应为这一原理提供了进一步的支持，该原理用于在二氟芳烃底物上实现邻位选择性取代。

  Click chemistry inspired facile synthesis and bioevaluation of novel triazolyl analogs of Ludartin

  摘要：

  A convenient and modular synthesis involving diastereoselective Michael addition followed by regioselective Huisgen 1,3-dipolar cycloaddition reaction was carried out to furnish 1,4-disubstituted-1,2,3-triazoles of Ludartin. This reaction scheme involving Michael addition followed by regioselective Huisgen 1,3-dipolar cycloaddition reaction leading to the formation of triazolyl analogs is being reported for the first time. All the triazolyl products were characterised using spectral data analysis. Sulphorhodamine B cytotoxicity screening of the resulting products against a panel of five human cancerous cell-lines revealed that few of the analogs display promising broad spectrum cytotoxic effect. Among all the synthesized compounds, only 3q displayed the best cytotoxic effect with IC50 values of 12, 11, 38, 39 and 8.5 mu M but less than the standard Ludartin (1) with IC50 values of 6.3, 7.4, 7.5, 6.9 and 0.5 mu M against human neuroblastoma (T98G), lung (A-549), prostate (PC-3), colon (HCT-116) and breast (MCF-7) cancer cell lines, respectively. The present synthesis was designed based on the previous literature reports of Ludartin as an aromatase inhibitor. Our work provides an initial study on structure-activity relationship of triazolyl analogs of sesquiterpene lactones in general and Ludartin (1) in particular. (C) 2014 Elsevier Ltd.

  A series of triazole based uracil derivatives were designed and synthesized as novel DPP-4 inhibitors. Compound A01 was identified as a lead compound for SAR studies focused on the structural modification at the S2′ subsite of DPP-4. The novel analogues A02–A25 were obtained by modifying the substituents at the phenyl group, and B01–B09, by introducing the carbonyl group. On screening in DPP-4, compounds

  设计并合成了一系列基于三唑的尿嘧啶衍生物，作为新型DPP-4抑制剂。化合物A01被确定为SAR研究的先导化合物，专注于DPP-4的S 2'亚位点的结构修饰。通过修饰苯基和B01-B09的取代基（通过引入羰基）获得了新的类似物A02-A25。在DPP-4中进行筛选时，与化合物A01相比，化合物B03，B04和B08的DPP-4抑制活性显着提高并显示出与市售DPP-4抑制剂阿格列汀相当的活性。对接研究在S揭示设计的化合物的新的有利的结合模式2'亚位点，并证明了在S结构修饰2'亚位点是增加DPP-4抑制的有效的选择。体外DPP-8和DPP-9测试表明，所有化合物均对DPP-8和DPP-9表现出优异的选择性。进一步的体内评估表明，化合物B04可以显着改善ICR小鼠的口服葡萄糖耐量，并剂量依赖性地降低2型糖尿病C57BL / 6小鼠的葡萄糖水平。这些数据表明化合物B04 可能是将来治疗T2DM的有希望的DPP-4抑制剂。
