Abstract: 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.

Abstract: The invention relates to novel N-benzoylamino acid derivatives of the general formula (I), ##STR1## wherein R.sup.1 and R.sup.2, which are the same or different, stand for a hydroxyl group optionally bearing an acetyl group; or a C.sub.1-6 alkoxy group optionally substituted by a phenyl group;n means an integer from 2 to 15as well as their tautomers, racemates and optically active individual (pure) isomers or mixtures thereof and the salts of these compounds and pharmaceutical compositions containing these compounds.The invention relates also to a process for the preparation of compounds of the general formula (I).

Abstract: This invention relates to novel compounds of the general formula (I) and the pharmaceutically acceptable acid addition salts thereof. In the general formula (I) ##STR1## wherein Lip, A.sup.1, A.sup.2, Het and n are defined as in the specification. The compounds of the general formula (I) inhibit the lipid peroxidation and therefore, they are useful for the treatment or prevention of diseases and conditions wherein the inhibition of lipid peroxidation is desirable.

Abstract: The present invention relates to novel compounds of the formula (I), ##STR1## wherein R.sub.1 and R.sub.2 stand independently from each other, for hydrogen, C.sub.1-4 alkyl, phenyl, phenyl-C.sub.1-4 alkyl, piridyl or piridyl-C.sub.1-4 alkyl group;E means a straight or branched, saturated hydrocarbon chain containing 1 to 6 carbon atoms;R.sub.3 represents: a phenyl group ortho-substituted by a C.sub.2-5 alkanoylamino, N-C.sub.2-5 alkanoyl-N-C.sub.1-4 alkylamino or di(C.sub.1-4 alkyl)amino group and optionally further substituted by halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy or C.sub.2-5 alkanoyloxy group; or a pyridyl group optionally mono- or polysubstituted by halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, C.sub.2-5 alkanoyloxy or phenyl-C.sub.1-4 alkoxy groupas well as their acid addition salts and tautomeric forms of these compounds.
