Melengestrol acetate-d2 is the deuterium labeled Melengestrol acetate. Melengestrol acetate is a progesterone derivative, acts as an orally activecorticosteroid hormoneto promote endometrial proliferation, pregnancy maintenance, and delay of menstrual activity^[1]. Melengestrol Acetate is used as acontraceptive agentfor growth promoting effects and suppression of estrus inanimals. Melengestrol acetate inhibits both the androgen-dependent and -independent prostatic tumorsin vivoand can be used forcancerresearch^[2].

Stable heavy isotopes of hydrogen, 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].
