- W1848278330 abstract "Purpose Aldehyde dehydrogenase (ALDH2) is an emerging drug target for the treatment of heart disease, cocaine and alcohol dependence, and conditions caused by genetic polymorphisms in ALDH2. Noninvasive measurement of ALDH2 activity in vivo could inform the development of these drugs and accelerate their translation to the clinic. Methods [1-13C, U-2H5] ethanol was hyperpolarized using dynamic nuclear polarization, injected into mice and its oxidation in the liver monitored using 13C MR spectroscopy and spectroscopic imaging. Results Oxidation of [1-13C, U-2H5] ethanol to [1-13C] acetate was observed. Saturation of the acetaldehyde resonance, which was below the level of detection in vivo, demonstrated that acetate was produced via acetaldehyde. Irreversible inhibition of ALDH2 activity with disulfiram resulted in a proportional decrease in the amplitude of the acetate resonance. Conclusion 13C magnetic resonance spectroscopy measurements of hyperpolarized [1-13C, U-2H5] ethanol oxidation allow real-time assessment of ALDH2 activity in liver in vivo.
