  • 摘要:

    Hyperpolarization of stable isotope-labeled substrates and subsequent NMR measurement of the metabolic reactions allow for direct tracking of cellular reactions in vitro and in vivo. Here, we report the hyperpolarization of 13C6-glucose- d 7 and evaluate its use as probes to observe glucose flux in cells. We measured the lifetime of the polarized signal governed by the spin–lattice relaxation time T 1. 13C6-Glucose- d 7 exhibited a T 1 that was over ten times as long as that of 13C6-glucose, and metabolic NMR studies of hyperpolarized 13C6-glucose- d 7 using tumor cell lysate led to observation of the resonances due to phosphorylated fluctofuranoses generated through aerobic glycolysis.
