摘要：

We report the first pretargeting in vivo study using the Strain-Promoted Sydnone-Alkyne Cycloaadition (SPSAC) reaction. The injection of a fluorine-18 labeled cyclooctyne three days after cetuximab bearing chlorosydnone moieties allowed a significant detection of the tumor by PET imaging suggesting an efficient click reaction inside the tumoral site. With a kinetic constant superior to 300 M-1 s(-1), the SPSAC reaction might be an interesting tool, in addition to tetrazine-cyclooctene ligation, for in vivo chemistry.
