First claim

The invention claimed is:

1. A compound of general formula (I), a single stereoisomer thereof, a mixture of stereoisomers thereof, and pharmaceutically acceptable salt thereof,

wherein,
X 1 is selected from hydrogen, halogen, nitro, nitroso, —SO 3 H or optionally substituted sulfonyl;
X 2 is independently selected from hydrogen, halogen, nitro, nitroso, —SO 3 H, optionally substituted amino or optionally substituted sulfonyl;
X 3 and X 4 are hydrogen;
said optionally substituted sulfonyl is selected from —SO 3 H, sulfonyl substituted with arylamino, sulfonyl substituted with alkyl sulfonyl substituted with alkyl substituted with alkoxy or sulfonyl substituted with halogen;
said optionally substituted amino is selected from amino substituted with alkylcarbonyl, amino substituted with hydroxy substituted alkylcarbonyl, amino substituted with alkylcarbonyl, amino substituted with alkenylcarbonyl, amino substituted with alkynylcarbonyl, amino substituted with alkoxycarbonyl, amino substituted with aryl substituted alkoxycarbonyl, amino substituted with cycloalkylcarbonyl, amino substituted with arylcarbonyl, amino substituted with halogen substituted arylcarbonyl, amino substituted with alkoxy substituted arylcarbonyl, amino substituted with haloalkyl substituted arylcarbonyl, amino substituted with furylcarbonyl, amino substituted with thienylcarbonyl, amino substituted with morpholinylcarbonyl, amino substituted with aminocarbonyl, amino substituted with alkoxycarbonylcarbonyl, amino substituted with alkylsulfonyl, amino substituted with alkenylsulfonyl, amino substituted with alkynylsulfonyl, amino substituted with alkoxysulfonyl, amino substituted with arylsulfonyl, amino substituted with nitro substituted arylsulfonyl, amino substituted with alkyl substituted arylsulfonyl, amino substituted with halogen substituted arylsulfonyl, amino substituted with aminosulfonyl or arylalkylsulfonyl substituted amino;
R 1 is independently selected from hydrogen, nitroso, alkyl, alkyl substituted with aryl, alkenyl, alkynyl, aryl, arylcarbonyl, alkylcarbonyl, alkenylcarbonyl or alkynylcarbonyl;
R 2 is hydrogen;
x is 1, 2 or 3;
y is 1, 2, 3 or 4; and
z is 1 or 2;
provided that:
X 1 , X 2 , X 3 and X 4 are not hydrogen simultaneously; and
when one of X 1 and X 2 is halogen, the rest of X 1 and X 2 are independently selected from hydrogen, nitro, nitroso, —SO 3 H, optionally substituted amino or optionally substituted sulfonyl, but they are not hydrogen simultaneously and X 1 is not optionally substituted amino.

2. A compound according to claim 1 , wherein
X 1 is selected from hydrogen, halogen, nitro, nitroso or —SO 3 H;
X 2 is independently selected from hydrogen, halogen, nitro, nitroso, amino or —SO 3 H;
R 1 is independently selected from hydrogen, nitroso, alkyl, alkyl substituted with aryl, alkenyl, alkynyl, aryl, arylcarbonyl, alkylcarbonyl, alkenylcarbonyl or alkynylcarbonyl;
x is 1, 2 or 3;
y is 1, 2, 3 or 4; and
z is 1 or 2;
provided that:
X 1 , X 2 , X 3 and X 4 are not hydrogen simultaneously; and
when one of X 1 and X 2 is halogen, the rest of X 1 and X 2 are independently selected from hydrogen, nitro, nitroso, amino or —SO 3 H, but they are not hydrogen simultaneously and X 1 is not amino.

3. A compound according to claim 1 , wherein X 1 is selected from hydrogen, halogen, nitro, nitroso, —SO 3 H, sulfonyl substituted with arylamino or sulfonyl substituted with alkyl; X 2 is independently selected from hydrogen, halogen, nitro, nitroso, —SO 3 H, amino substituted with alkylcarbonyl, amino substituted with alkenylcarbonyl, amino substituted with alkynylcarbonyl, amino substituted with alkoxycarbonyl, amino substituted with cycloalkylcarbonyl, amino substituted with arylcarbonyl, amino substituted with aminocarbonyl, amino substituted with furylcarbonyl, amino substituted with thienylcarbonyl, amino substituted with alkoxycarbonylcarbonyl, amino substituted with alkylsulfonyl, amino substituted with alkenylsulfonyl, amino substituted with alkynylsulfonyl, amino substituted with alkoxysulfonyl, amino substituted with arylsulfonyl, amino substituted with aminosulfonyl, sulfonyl substituted with arylamino or sulfonyl substituted with alkyl.

4. A compound of claim 1 , wherein R 1 is selected from hydrogen, nitroso, alkyl, aryl substituted alkyl, aryl, alkylcarbonyl or arylcarbonyl.

5. A compound of claim 1 , wherein y is 4.

6. A compound of claim 1 , wherein z is 2.

7. A compound of claim 1 , wherein X 1 is hydrogen, nitro or halogen.

8. A compound according to claim 1 , wherein R 1 is selected from hydrogen, nitroso, C 1 -C 6 alkyl, phenylcarbonyl or C 1 -C 6 alkylcarbonyl.

9. A compound according to claim 1 , wherein R 1 is selected from hydrogen, methyl, benzyl, benzoyl, nitroso or acetyl.

10. A compound according to claim 1 , wherein R 1 is selected from hydrogen, methyl, benzyl, benzoyl, nitroso or acetyl; and/or
