Method for labeling radioisotope, radiolabeling compounds using quinone compound and kit comprising the same for labeling radioisotope

Abstract

The present disclosure relates to a method for labeling a biomolecule, a fluorescent dye, or a nanoparticle compound with a radioisotope, comprising: (a) providing a cyclooctyne compound represented by the following formula (I) comprising the biomolecule, the fluorescent dye, or the nanoparticle compound which is bound to a cyclooctyne moiety of the cyclooctyne compound; and (b) reacting the cyclooctyne compound of formula (I) with a quinone compound represented by the following formula (II) to give a biomolecule, a fluorescent dye, or a nanoparticle compound labeled with the radioisotope: in formula (I), (Z is the biomolecule, the fluorescent dye, or the nanoparticle compound) in formula (II), (b is 0 or an integer from 1 to 10; L is CH2, —COO—, or —CONH—; M is the radioisotope).
