| abstract |
The present invention provides a compound that is represented by general formula (I) (In the formula, Z represents AA. Y n 1 represents N or CR 1 , Y 2 represents N or CR 2 , Y 3 represents N or CR 3 , and Y 4 represents N or CR 4 . One of R 1 -R 4 in these formulas represents a group represented by the belowmentioned formula -(L 1 ) n1 -Lg (In the formula, L1 represents a divalent linking group, n1 represents 0 or 1, and Lg represents a protein ligand), and the other three groups out of R 1 -R 4 represent hydrogen atoms or substituent groups, and one of R 5 -R 9 represents a group represented by the belowmentioned formula -(L 2 ) n2 -pr (In the formula, L2 represents a divalent linking group, n2 represents 0 or 1, and pr represents a probe), and the other 4 groups out of R 5 -R 9 represent hydrogen atoms or substituent groups), or a salt thereof. |
