Lapatinib-d₄  (Synonyms: GW572016-d₄; GW2016-d₄)

Lapatinib-d₄ is the deuterium labeled Lapatinib (HY-50898). Lapatinib is a potent inhibitor of the ErbB-2 and EGFR tyrosine kinase domains with IC50 values against purified EGFR and ErbB-2 of 10.2 and 9.8 nM, respectively[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].
