incorporating dipeptide were synthesized by facile acylation through benzotriazole mediated reactions and their structures were identified by 1H NMR, 13C NMR, MS and FT-IR spectroscopic techniques and elemental analysis. The carbonic anhydrase (CA, EC 4.2.1.1) inhibitory activity of the new compounds was assessed against four human (h) isoforms, hCA I, hCA II, hCA IV and hCA XII. Most of the synthesized
通过苯并三唑介导的反应进行酰化反应,合成了三十种新的二肽磺酰胺衍生物,并通过1 H NMR,13 C NMR,MS和FT-IR光谱技术及元素分析鉴定了其结构。评估了新化合物的碳酸酐酶(CA,EC 4.2.1.1)对四种人(h)同工型hCA I,hCA II,hCA IV和hCA XII的抑制活性。大多数合成的化合物在体外均表现出优异的性能碳酸酐酶的抑制特性可与临床使用的药物乙酰唑酰胺(AAZ)媲美。新的未保护的二肽-磺酰胺结合物显示出非常有效的抑制活性,在针对II和XII的低纳摩尔范围内,作为hCA I和IV抑制剂的效果较差。与AAZ相比,三十种化合物中的四种还显示出对hCA XII的强抑制活性。
