inhibitory activity of the new compounds was determined against four human (h) isoforms, hCA I, hCA II, hCA VA, and hCA XII. Most of the synthesised compounds showed effective in vitro CA inhibitory properties. The new amino acid-sulphonamide conjugates showed potent inhibitory activity against hCA II, some of them at subnanomolar levels, exhibiting more effective inhibitory activity compared to the
通过苯并三唑介导的偶联反应制备了一系列氨基酸-磺酰胺偶联物,并通过1H-NMR,13C-NMR,MS和FTIR光谱技术以及元素分析进行了表征。确定了新化合物的碳酸酐酶(CA,EC 4.2.1.1)对四种人(h)亚型hCA I,hCA II,hCA VA和hCA XII的抑制活性。大多数合成的化合物显示出有效的体外CA抑制特性。新的氨基酸-磺酰胺结合物显示出对hCA II的有效抑制活性,其中一些处于亚纳摩尔水平,与标准药物乙酰唑胺相比,具有更有效的抑制活性。还发现这些磺酰胺中的一些是hCA I,hCA VA和hCA XII的有效抑制剂,其活性范围从低至高纳摩尔范围。
