摘要: The invention relates to novel sulfonamidobenzoic acid derivatives having the general formula ##STR1## wherein R.sup.1 denotes a C.sub.1-4 alkoxy group or a hydrazino group or an NR.sup.4 R.sup.5 group, wherein R.sup.4 and R.sup.5 denote each a hydrogen atom or an identical or different C.sub.1-4 alkyl group; furthermore R.sup.4 may denote an aralkyl or substituted aralkyl group provided that R.sup.5 denotes a hydrogen atom; furthermore NR.sup.4 R.sup.5 may denote a morpholine or piperazine ring;R.sup.2 and R.sup.3 may denote each a hydrogen atom or an identical or different C.sub.1-4 aliphatic group; furthermore R.sup.2 may denote a cycloaliphatic, aralkyl, substituted aralkyl or amino group provided that R.sup.3 denotes a hydrogen atom; furthermore R.sup.2 and R.sup.3 may denote together with the adjacent nitrogen atom a morpholino ring, an unsubstituted piperazine ring or a substituted piperazine ring,and to their pharmaceutically acceptable acid addition salts. Furthermore, the invention relates to a process for preparing these compounds.The novel sulfonamidobenzoic acid derivatives having the general formula I possess significant tyrosine-paralyzing activity and thus they retard the biosynthesis of noradrenaline.
