2-e]- and [2,3-e]-1,2-thiazine-6-sulfonamide 1,1-dioxides were synthesized for evaluation as potential candidates for the treatment of glaucoma. All of the compounds prepared were potent high affinity inhibitors of human carbonic anhydrase II, Ki < 0.5 nM. Additionally, inhibition of recombinant human carbonic anhydrase IV was determined for selected compounds; these were shown to be moderate to potent
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%)。
