Xanthine-13C,15N2 is a 15N-labeled and 13C-labled Deruxtecan. Deruxtecan is an ADC drug-linker conjugate composed of a derivative of DX-8951 (DXd) and a maleimide-GGFG peptide linker, used for synthesizing DS-8201 and U3-1402.

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^[75].
