Talazoparib-13C,d4 is 13C and deuterated labeled Talazoparib (HY-16106). Talazoparib is an orally active PARP 1/2 inhibitor with Ki values of 1.2 nM and 0.87 nM for inhibiting PARP1 and PARP2 enzymatic activities, respectively. Has anti-tumor activity.
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].
