Asoprisnil-d3 (J867-d3) is the deuterium labeled Asoprisnil. Asoprisnil (J867), a selective progesterone receptor modulator, exhibits mixed progesterone agonist and antagonist effects on various progesterone targeted tissues in animal and human^[1].

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].
