Idasanutlin-d3-1 (RG7388-d3-1) is the deuterium labeled Idasanutlin. Idasanutlin is a potent antagonist of MDM2/p53. Idasanutlin inhibits relapsed or refractory acute myeloid leukemia.
Stable heavy isotopes of drogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs[1].
