RPR132595A-d3 is the deuterium labeled RPR132595A. RPR132595A is an active metabolite of CPT-11, which is generated by cytochrome P-450 3A4 (CYP3A4) and finally excreted through urine^[1][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].
