antitumor carbonic anhydrase inhibitors (CAIs), the obtained results represent an encouraging achievement for the development of new anticancer candidates without the common side effects of non-selective CAIs. Moreover, the lack of an explicit zinc binding function on these inhibitors opens the way towards the exploration of novel mechanisms of inhibition that could explain the high selectivity of these
合成了一系列N-烷基化糖精衍生物,并测试了其对人碳酸酐酶的四种不同同工型的抑制作用(CA,EC 4. 2.1.1):跨膜肿瘤相关的CA IX和XII,以及胞质CA I和二。大多数报道的衍生物在纳摩尔/低微摩尔范围内抑制CA XII,hCA IX的K I在11至390 nM之间,而对CA I(K I s> 50μM)和II(K I范围介于39.1 nM和50μM之间。由于CA I和II是抗肿瘤碳酸酐酶抑制剂(CAI)的脱靶靶标,因此获得的结果代表了开发新型抗癌候选药物的令人鼓舞的成就,而没有非选择性CAI的常见副作用。此外,在这些抑制剂上缺乏明确的锌结合功能为探索新的抑制机制开辟了道路,这可能解释了这些化合物对跨膜,与肿瘤相关的同工型相对于胞浆的同工型的高选择性。
