derivatives of probenecid, a well-known uricosuric agent, were synthesized and evaluated as inhibitors of human carbonic anhydrases (hCAs, EC 4.2.1.1). The transmembrane isoforms (hCA IX and XII) were potently and selectively inhibited by some of them. The proposed chemical modification led to a complete loss of hCA II inhibition (Kis > 10,000 nM) and enhanced the inhibitory activity against the tumour-associated
合成了新的丙磺舒酰胺衍生物,一种著名的尿酸尿酸药物,并作为人碳酸酐酶的抑制剂进行了评估(hCAs,EC 4.2.1.1)。跨膜同工型(hCA IX和XII)被其中一些有效和选择性抑制。拟议的化学修饰导致hCA II抑制作用完全丧失(K i s> 10,000 nM),并增强了对与肿瘤相关的hCA XII的抑制活性(化合物4的K i值为15.3 nM)。酶抑制数据也已通过hCA XII活性位点内化合物的对接研究得到验证。
