Olaparib-d 4 -1 is the deuterium labeled Olaparib. Olaparib (AZD2281; KU0059436) is a potent and orally active PARP inhibitor with IC50s of 5 and 1 nM for PARP1 and PARP2 , respectively. Olaparib is an autophagy and mitophagy activator. In Vitro 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid
