Patent ID: 7655643

Claim:
A compound of formula in which R 1 is selected from the group consisting of aminomethyl, 2-aminoethyl, 3-aminoprop-1-yl, 4-aminobut-1-yl, hydroxymethyl, 2-hydroxy-ethyl, aminocarbonylmethyl, 2-aminocarbonylethyl, 2-hydroxycarbonylethyl, 3-guanidinoprop-1-yl, 3-amino-2-hydroxyprop-1-yl and 4-amino-3-hydroxybut- 1-yl, R 2 is selected from the group consisting of hydrogen, methyl, ethyl and cyclopropyl, R 3 is —NR 6 R 7 , R 4 is selected from the group consisting of hydrogen, halogen, amino, hydroxy, hydroxycarbonyl, aminocarbonyl, nitro and methyl, R 5 is selected from the group consisting of hydrogen, halogen, amino, hydroxy, aminocarbonyl, hydroxycarbonyl, nitro and methyl, whereby R 5 is selected from the group consisting of halogen, amino, hydroxy, aminocarbonyl, hydroxycarbonyl, nitro and methyl, if R 4 is hydroxy, R 6 is selected from the group consisting of hydrogen, (C 1 -C 6 )-alkyl, (C 5 -C 6 )-cycloalkyl, 5- to 7-membered heterocyclyl and phenyl, whereby alkyl, cycloalkyl, heterocyclyl and phenyl may be substituted with 1 to 3 substituents, whereby said substituents are selected independently of one another from the group consisting of amino, hydroxy, aminocarbonyl, hydroxycarbonyl, (C 1 -C 4 )-alkyl, (C 1 -C 6 )-alkylamino, 5- to 7-membered heterocyclyl, phenyl, 5- or 6-membered heteroaryl, (C 1 -C 6 )-alkoxycarbonyl and (C 1 -C 6 )-alkylaminocarbonyl, in which alkyl, alkylamino, heterocyclyl, aryl, heteroaryl and alkylaminocarbonyl may be substituted with 1 to 3 substituents, whereby said substituents are selected independently of one another from the group consisting of amino, hydroxy, aminocarbonyl and hydroxycarbonyl, R 7 is selected from the group consisting of hydrogen and (C 1 -C 4 )-alkyl, whereby alkyl may be substituted with 1 to 2 substituents, whereby said substituents are selected independently of one another from the group consisting of amino, hydroxy and (C 1 -C 6 )-alkylamino, or R 6 and R 7 together with the nitrogen atom to which they are bonded form a piperazinyl, whereby piperazinyl may be substituted with 1 to 3 substituents, whereby said substituents are selected independently of one another from the group consisting of amino, hydroxy, optionally amino substituted (C 1 -C 6 )-alkyl, and (C 1 -C 6 )-alkylamino; or one of the salts thereof.
