Disclosed are compounds of the formula (I); wherein R1 and R2 are each independently of the other hydrogen, unsubstituted or substituted alkyl or cycloalkyl, a heterocyclic radical bonded via a ring carbon atom, or a radical of the formula R4-Y-(C=Z)- wherein R4 is unsubstituted, mono- or disubstituted amino or a heterocyclic radical, Y is either not present or lower alkyl and Z is oxygen, sulfur or imino, with the proviso that R1 and R2 are not both hydrogen; or R1 and R2 together with the nitrogen atom to which they are attached form a heterocyclic radical; R3 is a heterocyclic radical or an unsubstituted or substituted aromatic radical; G is C1-C7-alkylene, -C(=O)-, or C1-C6-alkylene wherein the carbonyl group is attached to the NR1R2 moiety; Q is -NH- or -O-, with the proviso that Q is -O- if G is -C(=O)- or C1-C6-alkylene-C(=O)-; and X is either not present or C1-C7alkylene, with the proviso that a heterocyclic radical R3 is bonded via a ring carbon atom if X is not present; or a salt thereof. Further disclosed is a process for the production of compounds of the formula (I) and the use of those compounds or their salts in the manufacture of a medicament. |
