A Click procedure with heterogeneous copper to tether technetium-99m chelating agents and rhenium complexes. Evaluation of the chelating properties and biodistribution of the new radiolabelled glucose conjugates
An efficient protocol was developed to tether chelating agents and rhenium complexes onto a glucoside scaffold with a heterogeneouscoppercatalyst via clickchemistry. The supportedcatalyst avoids the formation of unwanted copper complexes during the cyclisation step. The possibility to graft a pre-chelated M(CO)(3) core by clickchemistry onto a biomolecule was highlighted for the first time. (
