Conformationally Strained trans-Cyclooctene (sTCO) Enables the Rapid Construction of (18)F-PET Probes via Tetrazine Ligation.


The bioorthogonal reaction between tetrazines and trans-cyclooctenes is a method for the rapid construction of F-18 probes for PET imaging. Described here is a second generation (18)F-labeling system based on a conformationally strained trans-cyclooctene (sTCO)-a dienophile that is approximately 2 orders of magnitude more reactive than conventional TCO… (More)
