The present invention provides an 18F-labeled azide compound usable in the Huisgen reaction which enables 18F-labeling although only a small quantity of alkyne compound is available as a counterpart substrate, more specifically the 18F-labeled azide compound enabling the PET to be applied to peptides or oligonucleotides and enabling the 18F-labeling of any sites of oligonucleotide other than the 5' end or 3' end thereof, a reagent for 18F-labeling, and a method for 18F-labeling of an alkyne compound using the same.
[SOLVING MEANS]
An 18F-labeled azide compound according to the present invention is expressed by the following structural formula 1.
A novel method for F-18-radiolabeling of oligodeoxynucleotides (ODNs) by a Cu-catalyzed Huisgen reaction has been developed by using the lowest possible amount of the precursor biomolecule for the realization of stoichiometry-oriented PET (positron emission tomography) chemistry. Under the optimized cyclization conditions of p- or m-azido([F-18]fluoromethyl)benzene and alkyne-substituted ODN (20 nmol) at 40 degrees C for 15 min in the presence of CuSO4, TBTA [tris((1-benzyl-1H-1,2,3-triazol-4-yl)methyl) amine], and sodium ascorbate (2:1:2), the synthesis of F-18-labeled ODNs with sufficiently high radioactivities of 2.1-2.5 GBq and specific radioactivities of 1800-2400 GBq/mu mol have been accomplished for use in animal and human PET studies.
