WebMar 4, 2024 · A deuterated drug comprises diminutive molecules in which deuterium replaces one or more than one hydrogen atoms of the molecule. As deuterium and hydrogen possess almost similar physical properties, deuterium exchange is the smallest structural change that can be made to a molecule. This process is called deuteration. It is an …

WebDeuterium metabolic imaging or DMI is a recently described, innovative MR-based method to map metabolism non-invasively in 3D. DMI allows imaging of substrates and their metabolic products enriched with the non-radioactive and biocompatible deuterium (or 2 H) isotope.

WebDec 10, 2024 · Deuterated compounds can also be observed with MRI and they are somewhat less expensive than 13 C-labeled compounds. Like 13 C-labeled probes, they are metabolically equivalent to the unlabeled substrates and not radioactive. By gyromagnetic ratio and at 100% abundance, the sensitivity of deuterium is comparable to that of 13 C
