A compound of the formula Het--NR--SO.sub.2 --Ph.sup.2 --A--Ph.sup.1 (COOH)(OH) and tautomeric form, salts, solvates, C.sub.1-6 alkyl esters and pharmaceutical compositions of the compound. Ph.sup.1 and Ph.sup.2 are benzene rings with the proviso that carboxy and hydroxy are ortho to one another. Het includes an optionally substituted heterocyclic ring which includes conjugated double bonds and binds to nitrogen in NR. The compound is characterized in that A is a bridge which is stable against reduction because it is not azo, and in that R is hydrogen or lower alkyl. The invention also includes the preparation of the compound and its use as a drug, particularly for treating autoimmune diseases.
