Prostate-specific membrane antigen (PSMA) binding compounds having radioisotope substituents are described, as well as chemical precursors thereof. Compounds include pyridine containing compounds, compounds having phenylhydrazine structures, and acylated lysine compounds. The compounds allow ready incorporation of radionuclides for single photon emission computed tomography (SPECT) and positron emission tomography (PET) for imaging, for example, prostate cancer cells and angiogenesis.

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.

A method of synthesis of a mono-substituted tin compound comprises contacting a stannous halide with a metalated reactant to form a stannylene compound; contacting the stannylene compound with a halide compound to form a stannic compound; and contacting the stannic compound with a reactant to form a mono-substituted tin compound via ligand exchange. A composition comprising the mono-substituted tin compound is also provided, among other compositions and methods.
