Rational design of compounds that would bind specific pockets of the target proteins is a difficult task in drug design. The 12 isoforms of catalytically active human carbonic anhydrases (CAs) have highly similar active sites that make it difficult to design inhibitors selective for one or several CA isoforms. A series of CA inhibitors based on 2-chloro/bromo-benzenesulfonamide that is largely fixed
结合靶蛋白特定口袋的化合物的合理设计在药物设计中是一项艰巨的任务。催化活性人碳酸酐酶(CAs)的12种同工型具有高度相似的活性位点,这使得难以设计对一种或几种CA同工型具有选择性的抑制剂。基于2-氯/溴-苯磺酰胺的一系列CA抑制剂(主要固定在CA活性位点上)与一个或两个尾巴一起产生,这些化合物经合成并被评估为CA同种型的抑制剂。引入第二条尾巴会对结合亲和力产生重大影响,并且在大多数情况下,双尾化合物对CA IX和CA XIV具有很高的亲和力和选择性。通过X射线晶体学测定几种化合物与CA氨基酸之间的接触。
