Palbociclib-d₈  (Synonyms: PD 0332991-d₈)

Palbociclib-d₈ is a deuterium labeled Palbociclib. Palbociclib is a selective and orally active CDK4 and CDK6 inhibitor with IC50s of 11 and 16 nM, respectively. Palbociclib has the potential for ER-positive and HER2-negative breast cancer research[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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
