The present invention relates to novel tetrazine compounds of formula I, wherein one of R1-R5 is 18F, for use in pretargeted in vivo imaging. The compounds are suitable for use in click chemistry, i.e. reactions that join a targeting molecule and a reporter molecule. The invention further relates to precursors to formula I, wherein one of R1-R5 is SnR3, B(OR)2, B(0H)2. Formula (I).

The present invention relates to novel tetrazine compounds for use in pretargeted in vivo imaging and in therapy and to the precursors of the tetrazine compounds. The compounds are suitable for use in click chemistry, i.e. reactions that join a targeting molecule and a reporter molecule. The compounds comprise a radionuclide of F, I or At and on or more polar groups providing that the compounds can efficiently react with extracellularly located pretargeting vectors and as such used for example for pretargeted cancer diagnostics and cancer therapy.
