In the present work, a new series of thiopyrimidine-benzenesulfonamide conjugates was designed, synthesized and tested as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. Our design strategy was based on the molecular hybridization of the benzenesulfonamide moiety as a zinc binding group (ZBG), an alkylated thiopyrimidine moiety as a spacer and (un)substituted phenyl moieties with various electronic
在本工作中,设计,合成和测试了一系列新的硫代嘧啶-苯磺酰胺共轭物,作为碳酸酐酶(CA,EC 4.2.1.1)抑制剂。我们的设计策略基于作为锌结合基团(ZBG)的苯磺酰胺部分,作为间隔基的烷基化硫代嘧啶部分和具有各种电子和疏水环境的(未)取代苯基部分作为尾巴的分子杂交。针对四种人(h)CA同工型hCA I,hCA II,hCA IX和hCA XII对设计和合成的化合物进行了评估。系列6显示出对细胞质同工型hCA I和hCA II相对于膜结合同工型hCA IX和hCA XII有希望的活性和选择性。与hCA I,hCA IX相比,化合物6e和6f对hCA II的Ki值为0.04 µM,对hCA II的选择性为15.8-980倍。hCA XII亚型。hCA II活性位点的分子对接归因于系列6的有希望的抑制活性,归因于它们的磺酰胺部分与活性位点Zn2 +离子的相互作用,以及其与关键氨基酸Thr199
