selective human carbonic anhydrase inhibitors (hCAIs), we synthesized 4‐sulfamoylphenyl/sulfocoumarin benzamides (series 5 a–r and series 7 a–q) and evaluated their inhibition profiles against five isoforms of the zinc‐containing human carbonic anhydrase (hCA, EC 4.2.1.1): cytosolic hCA I and II, and the transmembrane isozymes hCA IV, IX, and XII. Compounds 5 a–r were found to selectively inhibit hCA II
为了开发有效的和选择性的人类碳酸酐酶抑制剂(hCAIs),我们合成了4-氨磺酰基苯基/磺基香豆素苯甲酰胺(系列5 a – r和系列7 a – q),并评估了它们对含锌的五种同工型的抑制谱。人碳酸酐酶(hCA,EC 4.2.1.1):胞质hCA I和II,以及跨膜同工酶hCA IV,IX和XII。化合物5 a – r据发现,它们在纳摩尔范围内选择性抑制hCA II,而对其他hCA亚型的抑制作用较弱。从文献中可以看出,磺基香豆素(1,2-苯并氧杂氨酸2,2-二氧化物)充当“前药”抑制剂,并通过hCA的酯酶活性水解形成2-羟基苯基乙烯基磺酸,然后与酶结合。类似于香豆素和磺氧香豆素的方式。所有这些磺基香豆素(化合物7 a – q)被发现作为管家脱靶hCA异构体I和II的抑制剂非常弱或无效,并在高纳摩尔至微摩尔范围内有效抑制跨膜肿瘤相关的亚型IX和XII。这些分子的进一步结构修饰可用于开发用于治疗青光眼,癫痫和癌症的有效hCA抑制剂。
