Abstract

A compound represented by general formula (I) or (II) or a salt thereof and an agent for measurement of a reactive oxygen comprising said compound or a salt thereof: wherein R 1 and R 2 independently represent an aryl group which may be substituted, e.g., a phenyl group substituted with an amino group or a hydroxy group, and R 3 represents a 2-carboxyphenyl group which may be substituted.

Claims (25)

1. A compound represented by general formula (I) or (II) or a salt thereof:

wherein R 1 and R 2 independently represent an aryl group which may be substituted and R 3 represents a 2-carboxyphenyl group which may be substituted.

2. The compound or a salt thereof according to claim 1 , wherein R 1 and R 2 represent a phenyl group substituted with an amino group or a hydroxy group.

3. The compound or a salt thereof according to claim 1 , wherein R 3 is a 2-carboxyphenyl group.

4. An agent for measurement of a reactive oxygen which comprises the compound according to claim 1 or a salt thereof.

5. A method for measurement of a reactive oxygen, which comprises the steps of:

(A) reacting the compound according to claim 1 or a salt thereof with a reactive oxygen; and

(B) measuring fluorescence of a dearylated compound or a salt thereof generated in the above step (A).

6. A method for measurement of an enzymatic activity of an enzyme, in which a reactive oxygen involves in said enzymatic activity, by using the compound according to claim 1 or a salt thereof.

7. The method according to claim 6 , wherein the enzyme is a peroxidase.

8. An agent for measurement of an enzymatic activity of an enzyme, in which a reactive oxygen involves in said enzymatic activity, which comprises the compound according to claim 1 or a salt thereof.

9. The agent according to claim 8 , wherein the enzyme is a peroxidase.

10. The compound or a salt thereof according to claim 2 , wherein R 3 is a 2-carboxyphenyl group.

11. An agent for measurement of a reactive oxygen which comprises the compound according to claim 2 or a salt thereof.

12. An agent for measurement of a reactive oxygen which comprises the compound according to claim 3 or a salt thereof.

13. A method for measurement of a reactive oxygen, which comprises the steps of:

(A) reacting the compound according to claim 2 or a salt thereof with a reactive oxygen; and

(B) measuring fluorescence of a dearylated compound or a salt thereof generated in the above step (A).

14. A method for measurement of a reactive oxygen, which comprises the steps of:

(A) reacting the compound according to claim 3 or a salt thereof with a reactive oxygen; and

(B) measuring fluorescence of a dearylated compound or a salt thereof generated in the above step (A).

15. A method for measurement of an enzymatic activity of an enzyme, in which a reactive oxygen involves in said enzymatic activity, by using the compound according to claim 2 or a salt thereof.

16. A method for measurement of an enzymatic activity of an enzyme, in which a reactive oxygen involves in said enzymatic activity, by using the compound according to claim 3 or a salt thereof.

17. An agent for measurement of an enzymatic activity of an enzyme, in which a reactive oxygen involves in said enzymatic activity, which comprises the compound according to claim 2 or a salt thereof.

18. An agent for measurement of an enzymatic activity of an enzyme, in which a reactive oxygen involves in said enzymatic activity, which comprises the compound according to claim 3 or a salt thereof.
