NOVEL MALEIMIDE COMPOUND HAVING 1,2,3-TRIAZOLE GROUP, PREPARATION METHOD THEREOF AND F-18 LABELING METHOD OF BIOMOLECULE USING PROSTHETIC GROUP

摘要

PURPOSE: A maleimide compound labeled with fluorine-18(^18F) and a method for labeling ^18F of biocompounds are provided to simplify production process and to reduce production time. CONSTITUTION: A maleimide compound with 1,2,3-triazole group is denoted by chemical formula 1. A method for preparing the maleimide compound comprises: a step of performing nucleophilic fluorination of sulfonate precursor of chemical formula 2 under the presence of an organic solvent to prepare fluoroalkyl azide compound of chemical formula 3; and a step of reacting the compound of chemical formula 3 with maleimide with terminal alkyne group of chemical formula 4 under the presence of an organic solvent and copper catalyst to prepare a compound of chemical formula 1. A method for labeling ^18F to a biocompound comprises: a step of stirring ^18F-labeled compound of chemical formula 1 with the biocompound with SH functional groups under the presence of PBS solution; and a step of collecting ^18F-labeled biocompound of chemical formula 6.
