  Quaternary ammonium substituted thieno[3,2-e]-1,2-thiazine-6-sulfonamide 1,1-dioxides: Potential membrane-impermeable inhibitors of carbonic anhydrase

  摘要：

  Thieno[3,2-e]-1,2-thiazine-6-sulfonamide 1,1-dioxides, which have a quaternary ammonium moiety incorporated into their structures, were synthesized. All of the quaternary ammonium salts prepared in the present study are potent inhibitors of both human carbonic anhydrase-II and recombinant human carbonic anhydrase-IV; they are significantly more potent as inhibitors of these carbonic anhydrase isozymes than the previously reported inhibitor quatemary ammonium homosulfanilamide. By virtue of the permanent cationic charge on these compounds they are anticipated to be membrane-impermeable inhibitors of carbonic anhydrase. Spiro quaternary ammonium compounds, such as 15 and 16, when formed by intracellular cyclization following transport of a suitable precursor molecule, such as 14, may be selective prolonged inhibitors of cytosolic carbonic anhydrase due to intracellular entrapment.

  摘要：

  合成了新型非手性2H-噻吩并[3,2-e]-和[2,3-e] -1,2-噻嗪-6-磺酰胺1,1-二氧化物，以评估其作为治疗青光眼的潜在候选药物。制备的所有化合物均为人碳酸酐酶II的有效高亲和力抑制剂，Ki <0.5 nM。另外，对于选择的化合物，测定了对重组人碳酸酐酶IV的抑制作用。这些化合物被证明是该同功酶的中度至强效抑制剂，IC50值为4.25至73.6 nM。在评估了其在自然高血压的荷兰带状兔中降低眼内压的能力的化合物中，局部给药后，该模型中的5a，17a3、17b1、17b2、17h2和17i1在此模型中显示出显着的功效（降低幅度> 20％）。
