were designed, synthesized and evaluated against four human carbonic anhydrase isoforms belonging to α family comprising of two cytosolic isoforms hCA I and II as well as two transmembrane tumor associated isoforms hCA IX and XII. Starting from these derivatives that showed high potency but low selectivity in favor of tumor associated isoforms hCA IX and XII, we investigated the impact of removing the
设计,合成和评估了新型吡唑基苯并[d]咪唑衍生物(2a-2f),并针对四种属于α家族的人碳酸酐酶同工型,其中包括两个胞质同工型hCA I和II,以及两个跨膜肿瘤相关同工型hCA IX和XII。从显示出高效力但低选择性的这些衍生物开始,支持肿瘤相关同工型hCA IX和XII,我们研究了去除磺酰胺基团的影响。因此,合成了没有磺酰胺部分的类似物3a-3f,并且生物学测定显示出作为与肿瘤相关的hCA IX和hCA XII的抑制剂的良好的活性以及优异的选择性,并且通过分子对接研究对其进行了分析。
