the 2-mercapto-quinazolin-4-one ring) led to highly effective hCA II/XII inhibitors. These compounds should thus be of interest as preclinical candidates in pathologies in which the activity of these enzymes should be inhibited, such as glaucoma (CA II and XII as targets) or some tumors in which the activity of isoforms CA II and XII is dysregulated.
取代的邻氨基苯甲酸与4-异硫氰酸根合乙基-苯磺酰胺的缩合导致形成一系列带有2-巯基-喹唑啉-4-酮尾基的杂环苯磺酰胺。研究了这些磺酰胺作为人碳酸酐酶(hCA,EC 4.2.1.1)异构体hCA I和II(胞质同工酶)以及hCA XII(跨膜的肿瘤相关酶,也参与青光眼的发生)的抑制剂。新的磺酰胺类药物可作为hCA I(KI的28.5-2954nM)的中效抑制剂,作为hCA II(KI的0.62-12.4nM的抑制剂)和XII(KI的0.54-7.11nM)的抑制剂非常有效。这些化合物中存在的所有取代模式(例如,2-巯基喹唑啉-4-酮环的6、7和/或8位上的卤素,甲基和甲氧基)导致高效的hCA II / XII抑制剂。
