Substituted sulphonamides having the general formula (I) and salts, hydrates and solvates thereof were prepared and described, wherein R1 is CO or SO2 and R2 is NH or O and where R represents linear or cyclic aliphatic chain and n represents number of linking aliphatic chain carbons (n can be 0, 1, 2 or 3), which are useful in the manufacture of the medicaments due to the carboanhydrase inhibition. These compounds are prepared by nucleophilic reaction of an amine with 4-sulfamoylbenzenesulphonyl chloride in the presence of triethylamine excess in tetrahydrofurane or in ether at temperature 0 to 20° C. The compounds show an antiglaucomatic activity.
制备并描述了具有通式(I)及其盐,水合物和溶剂化物的取代磺酰胺化合物,其中R1为CO或SO2,R2为NH或O,而R代表线性或环状脂肪链,n代表连接脂肪链碳的数量(n可以为0、1、2或3),这些化合物由于碳酸酐酶抑制作用在制药方面有用。这些化合物通过在四氢呋喃或醚中以0至20°C的温度下,在三乙胺过量存在下,通过胺的亲核反应与4-磺酰基苯磺酰氯反应制备而成。这些化合物表现出抗青光眼活性。
