Claim:
A 3-Aminophenol derivative of formula (I), or a physiologically compatible, water-soluble salts thereof: wherein R1 represents a group of formula (II) or (III) wherein R2, R3, R4, R5 and R6 independently of each other denote hydrogen, a halogen atom, a cyano group, a hydroxyl group, a C 1 –C 4 -alkoxy group, a phenoxy group, a C 2 –C 4 -hydroxyalkoxy group, a C 1 –C 6 -alkyl group, a phenyl group, a C 1 –C 4 -alkyl thioether group, a mercapto group, a nitro group, an amino group, a C 1 –C 4 -alkylamino group, a hydroxy-(C 2 –C 4 )-alkylamino group, a di(C 1 –C 4 )-alkylamino group, a di[hydroxy-(C 2 –C 4 )alkyl]amino group, a [dihydroxy-(C 3 –C 4 )-alkyl]amino group, a [hydroxy-(C 2 –C 4 )-alkyl]-C 1 –C 4 -alkylamino group, a trifluoromethyl group, a formyl group, an acetyl group, a trifluoroacetyl group, a trimethylsilyl group, a (C 1 –C 4 )-hydroxyalkyl group, a (C 2 –C 4 )-dihydroxyalkyl group, a (C 1 –C 4 )-aminoalkyl group or a (C 1 –C 4 )-cyanoalkyl group, or two adjacent R2 to R6 groups together with a remaining portion of the group of formula (II) form a heterocyclic or carbocyclic, substituted or unsubstituted ring; with the proviso that at least one of R2, R3, R4, R5 and R6 is other than hydrogen X1, X2, X3, X4 and X5 independently of each other denote nitrogen or a C—R7 group, C—R8 group, C—R9 group, C—R10 group or C—R11 group, provided that at least one and at the most three of the X 1 to X 5 groups denote nitrogen; and R7, R8, R9, R10 and R11 independently of each other denote hydrogen, a halogen atom, a cyano group, a C 1 –C 6 -alkyl group, a (C 1 –C 4 )-alkyl thioether group, a mercapto group, a nitro group, an amino group, a C 1 –C 4 -alkylamino group, a hydroxy-(C 2 –C 4 )-alkylamino group, a di(C 1 –C 4 )-alkylamino group, a di[hydroxy(C 2 –C 4 )-alkyl]amino group, a [dihydroxy-(C 3 –C 4 )-alkyl]amino group, a [hydroxy-(C 2 –C 4 )-alkyl]-C 1 –C 4 -alkylamino group, a trifluoromethyl group, a formyl group, an acetyl group, a trifluoroacetyl group, a trimethylsilyl group, a carbamoyl group, a (C 1 –C 4 )-hydroxyalkyl group or a (C 2 –C 4 )-dihydroxyalkyl group.
