modelling studies focused the attention on the binding mode of these compounds to the enzyme. The proposed inhibition mechanism is the anchoring to zinc-bound water molecule. Docking studies along with moleculardynamics also underlined the importance of the compounds flexibility (e.g. achieved through the insertion of methylene group) which favoured potent and selective hCA inhibition.
摘要 已经合成了糖精和乙酰磺胺酸衍生物的大型文库,并针对人碳酸酐酶的四种同工型,两种脱靶的hCA I / II和与肿瘤相关的同工型hCA IX / XII进行了评估。糖精和乙酰磺胺酸核心都尝试了不同的支架修饰策略,从而获得了60种化合物。它们中的一些表现出在纳摩尔范围内的抑制活性,尽管某些进行的改变导致针对hCA IX / XII的微摩尔活性或不存在。分子模型研究将注意力集中在这些化合物与酶的结合方式上。拟议的抑制机制是锚定在锌结合的水分子上。对接研究以及分子动力学也强调了化合物灵活性的重要性(例如,

antitumor carbonicanhydraseinhibitors (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
