A series of 5-substituted thieno[2,3-b]- and thieno[3,2-b)- and thieno[3,2-b)thiophene-2-sulfonamides was prepared and evaluated for topical ocular hypotensive activity in glaucoma models. The 5-substituents were varied to maximize both inhibitory potency against carbonic anhydrase and water solubility. At the same time, these substituents were varied in order to obtain compounds with the appropriate
制备了一系列5-取代的噻吩并[2,3-b]-,噻吩并[3,2-b]-和噻吩并[3,2-b]噻吩-2-磺酰胺,并对其在青光眼中的局部降压活性进行了评估楷模。改变5-取代基以最大化对碳酸酐酶的抑制能力和水溶性。同时,改变这些取代基以获得具有适当pKa的化合物,以使虹膜中的色素结合最小化。所有这些变量均在最佳化合物5-[[[(甲氧基乙基)[(甲氧基乙基)乙基]氨基]甲基]噻吩并[2,3-b]噻吩-2-磺酰胺盐酸盐中进行了优化(55)。
