An N-benzoylamino acid compound of the formula (I), ##STR1## wherein R.sup.3 is an NR.sup.4 R.sup.5 group where R.sup.4 and R.sup.5 which are the same or different are selected from the group consisting of hydrogen, a hydroxyl group, a C.sub.1-12 alkyl group, a C.sub.1-4 alkyl group substituted by a hydroxyl group and a C.sub.1-4 alkyl group substituted by an amino group; R.sup.4 and R.sup.5 when taken together with the adjacent nitrogen form a substituted or unsubstituted 5- or 6-membered heterocyclic group, a 5- or 6-membered heterocyclic group containing an additional nitrogen atom, a 5- or 6-membered heterocyclic group containing an additional nitrogen atom and being substituted by an oxo group, a phenyl-substituted C.sub.1-4 alkyl group or C.sub.3-5 alkenyl group; with the proviso that when the heterocyclic group is piperazine, this heterocyclic group may also be substituted by a diaminopyrimidinyl or di(pyrrolidino)-pyrimidinyl group; n is an integer from 2 to 15; and their tautomers, racemates and the pure optically active individual isomers or mixtures thereof, and a pharmaceutically acceptable salt thereof is described. These compounds are useful for the treatment of patients suffering from disorders being in an indirect or direct connection with pathological oxidation processes occurring in the organism, particularly ischaemic and reperfusion tissue injuries, inflammations, atherosclerosis, or degenerative neurological disorders.
