SUBSTITUTED SULPHONAMIDES, PROCESS FOR THEIR PREPARATION, PHARMACEUTICAL COMPOSITION COMPRISING THEREOF AND THEIR USE

摘要

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.
