Zusammenfassung:Sulphonamide derivatives of the formula I …… in which R is a C1-4-alkyl or phenyl group which can be substituted by halogen atoms, trifluoromethyl or C1-4-alkyl groups, R is a hydrogen atom or a C1-4-alkyl group, A is one of the groups CHOR , C=O, C=S or C=N-OR where R is a hydrogen atom, a C1-4-alkyl, phenyl, benzyl or C1-4-acyl group and R is a hydrogen atom or a methyl group, B can be a meta or para methylene, ethylene or, if A is not a carbonyl group, a methyleneoxy group, where the oxygen atom is bonded to the aromatic ring, E can be a carboxyl, phospho or sulpho radical, their physiologically suitable salts, esters with C1-4-alcohols and amides, and the tetrazol-5-yl radical, their preparation and use as pharmaceuticals.
