Deuterated chemistry
Did you know?
A deuterated drug is a small molecule medicinal product in which one or more of the hydrogen atoms contained in the drug molecule have been replaced by its heavier stable isotope deuterium. Because of the kinetic isotope effect, deuterium-containing drugs may have significantly lower rates of metabolism, and hence a longer half-life. WebThe Chemistry Deuterated aldosterone, available since 2004, exists in solution in equilibrium between two forms in roughly a 60:40 ratio (see Figure 3). The mass spectra of the unlabeled and labeled standards are shown in Figures 4a and 4b. The top spectrum shows unlabeled aldosterone with the M+H molecular ion seen at m/z 343.16. The
