摘要

Disclosed are acyl-4-carboxyphenylurea derivatives of the formula (I) including their physiologically acceptable salts. Further disclosed is a process for the production of compounds of formula (I) which comprises reacting ureas of formula (2) or aniline derivatives of the formula (3) with aroyl isocyanates, with reactive acid derivatives, with acid chlorides or with anhydrides, of the formula (4). Still further disclosed is the use of compounds of formula (I) for the production of a medicament for the treatment of type-2 diabetes or for lowering blood sugar.
