Small libraries of N-substituted saccharin and N-/O-substituted acesulfame derivatives were synthesized and tested as atypical and selective inhibitors of four different isoforms of human carbonic anhydrase (hCA I, II, IX and XII, EC 4.2.1.1). Most of them inhibited hCA XII in the low nanomolar range, hCA IX with KIs ranging between 19 and 2482 nM, whereas they were poorly active against hCA II (KIs
合成了小的N-取代的糖精和N- / O-取代的乙酰磺胺衍生物文库,并作为人类碳酸酐酶的四种不同同工型(hCA I,II,IX和XII,EC 4.2.1.1)的非典型和选择性抑制剂进行了测试。他们中的大多数在低纳摩尔范围内抑制hCA XII,hCA IX的K I在19和2482 nM之间,而对hCA II(K I s> 10μM)和hCA I(K I范围介于318 nM和50μM之间。由于hCA I和II是普遍存在的脱靶同工型,而癌症相关的同工型hCA IX和XII最近已被验证为药物靶标,因此这些结果在开发新的抗癌候选药物中取得了令人鼓舞的成就。此外,这些抑制剂的结构中缺乏经典的锌结合基团为不同的抑制机制开启了创新的,尚未探索的场景,这可能解释了高抑制选择性。已经进行了一种计算方法以进一步合理化生物学数据并表征这些抑制剂中某些抑制剂的结合模式。
