Hyperpolarized [2-13C]-fructose Enables In Vivo Metabolic Imaging

Strategic Insights

— 1 min read

Scientists in the United States have successfully hyperpolarized [2-13C]-fructose, a hemiketal DNP substrate, for in vivo metabolic imaging. This breakthrough enables the exploration of upstream glycolytic processes, which have been linked to various metabolic disorders, including cancer, fatty liver disease, and diabetes. The hyperpolarized [2-13C]-fructose exhibits a sufficient T(1) and solution-state polarization for ex vivo spectroscopy and in vivo spectroscopic imaging studies.

Key Takeaways:

  • Researchers have developed a hyperpolarized [2-13C]-fructose substrate using dynamic nuclear polarization (DNP) for in vivo metabolic imaging.
  • This innovation targets carbohydrate carbons, which have previously been challenging to investigate due to their short T(1) relaxation times.
