  4-Substituted thiophene- and furan-2-sulfonamides as topical carbonic anhydrase inhibitors

  摘要：

  A series of 4-substituted thiophene- and furan-2-sulfonamides was prepared and was found to possess nanomolar-level potency for inhibition of human carbonic anhydrase II in vitro. Selected examples from this group were further evaluated for their potential to act as topically effective ocular hypotensive agents in the ocular normotensive albino rabbit and the ocular alpha-chymotrypsinized rabbit. Solubility studies in water and pH 7.4 buffer were carried out to estimate the ability of compounds to be formulated in solution. The sensitization potential of key representative structures was determined by in vitro glutathione reactivity studies and guinea pig maximization testing.

  SO(2) efficient: A three‐component palladium‐catalyzed coupling of aryl lithium compounds; sulfur dioxide (provided by the easy‐to‐handle solid surrogate, DABSO); and aryl, heteroaryl, and alkenyl (pseudo)halides yields a diverse library of sulfones. An electron‐poor XantPhos‐type ligand suppresses aryl–aryl exchange and is key to obtaining high yields.

  SO（2）高效：芳基锂化合物的三组分钯催化偶联；二氧化硫（由易于处理的固体替代物 DABSO 提供）；和芳基、杂芳基和烯基（伪）卤化物产生不同的砜库。缺电子 XantPhos 型配体抑制芳基-芳基交换，是获得高产率的关键。
