Abstract
5-Aminosalicylic acid O-sulfates of physiologically acceptable bases are new substances which are preparable by esterification of 5-nitrosalicylic acid alkyl esters with carbodiimide and sulfuric acid, alkaline saponification of the alkyl ester group and reduction of the thus obtained 5-nitrosalicylic acid O-sulfates. Said substances are useful as drugs, more specifically for the treatment of colitis ulcerosa, enteritis regionalis Crohn (morbus Crohn), chronic nonspecific colitis and diverticulitis.
