The present application discloses compositions and methods of synthesis and use involving click chemistry reactions for in vivo or in vitro formation of therapeutic and/or diagnostic complexes. Preferably, the diagnostic complex is of use for 18 F imaging, while the therapeutic complex is of use for targeted delivery of chemotherapeutic drugs or toxins. More preferably, a chelating moiety or targetable construct may be conjugated to a targeting molecule, such as an antibody or antibody fragment, using a click chemistry reaction involving cyclooctyne, nitrone or azide reactive moieties. In most preferred embodiments, the click chemistry reaction occurs in vivo. In vivo click chemistry is not limited to 18 F labeling but can be used for delivering a variety of therapeutic and/or diagnostic agents. |
