Labeling biomolecules with F-18 is usually done through coupling with prosthetic groups, which generally requires several time-consuming radiosynthetic steps resulting in low labeling yield. Recently, the tetrazine-trans-cyclooctene ligation has been introduced as a method of bioconjugation that proceeds with fast reaction rates without need for catalysis. Herein, we report the development of an extremely fast and efficient method for generating F-18 labeled probes based on the tetrazine-trans-cyclooctene ligation. Starting with only 30 mu g (78 mu M) of a tetrazine-RGD conjugate and 2 mCi (5 mu M) of F-18-trans-cyclooctene, the F-18 labeled RGD peptide could be obtained in more than 90% yield within five minutes. The F-18 labeled RGD peptide demonstrated prominent tumor uptake in vivo. The receptor specificity was confirmed by blocking experiments. These results successfully demonstrate that the tetrazine-trans-cyclooctene ligation serves as an efficient labeling method for PET probe construction. (C) 2011 Elsevier Ltd. All rights reserved.
