A series of benzenesulfonamides incorporating cyanoacrylamide moieties (tyrphostine analogues) have been obtained by reaction of sulfanilamide with ethylcyanoacetate followed by condensation with aromatic/heterocyclic aldehydes, isothiocyanates or diazoniumsalts. The new compounds have been investigated as inhibitors of the metalloenzyme carbonic anhydrase (CA, EC 4. 2.1.1), and more specifically
通过使磺酰胺与氰基乙酸乙酯反应,然后与芳族/杂环醛,异硫氰酸酯或重氮盐缩合,已获得了一系列结合了氰基丙烯酰胺基团(酪氨酸类似物)的苯磺酰胺。已经研究了这些新化合物作为金属酶碳酸酐酶(CA,EC 4. 2.1.1)的抑制剂,并且更具体地针对胞质人(h)亚型hCA I和II,以及与肿瘤相关的跨膜化合物CA IX和XII,它们是经过验证的抗肿瘤靶标。大多数新的苯磺酰胺是低纳摩尔或亚纳摩尔量的CA IX / XII抑制剂,而它们作为CA I和II的抑制剂效果较差。还讨论了这类有效的CA抑制剂的构效关系。一般来说,
