  • Methods to prepare carbon-isotope labeled organohalides with high specific radioactivity from carbon-isotope monoxide
    Patent number: 7659317
    Abstract: Methods and reagents for labeling synthesis of organohalides by transition metal mediated carbonylation reactions using carbon-isotope labeled carbon monoxide are provided. The resultant carbon-isotope labeled organohalides are useful as radiopharmaceuticals, especially for use as precursors in Positron Emission Tomography (PET). Associated PET tracers and kits for PET studies are also provided.
    Type: Grant

  • Labelled compound
    Patent number: 5847193
    Abstract: The present invention provides a labelled .beta.-cyano-L-alanine and a .gamma.-cyano-.alpha.-aminobutyric acid, of which cyano group carbon is labelled with radionuclide .sup.11 C or .sup.14 C, or stable isotope .sup.13 C. The present invention also provides a labelled amino acids such as asparagine, asparatic acid, DABA, GABA, glutamine and glutamic acid synthesized by using the labelled .beta.-cyano-L-alanine and the .gamma.-cyano-.alpha.-aminobutyric acid as an intermediate. The labelled amino acids are useful for in vivo imaging of tumors and brain functions.
