Imatinib-d₃ hydrochloride  (Synonyms: STI571-d₃ hydrochloride; CGP-57148B-d₃ hydrochloride)

Imatinib-d₃ (hydrochloride) is the deuterium labeled Imatinib. Imatinib (STI571) is an orally bioavailable tyrosine kinases inhibitor that selectively inhibits BCR/ABL, v-Abl, PDGFR and c-kit kinase activity. Imatinib (STI571) works by binding close to the ATP binding site, locking it in a closed or self-inhibited conformation, therefore inhibiting the enzyme activity of the protein semicompetitively. Imatinib also is an inhibitor of SARS-CoV and MERS-CoV.

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].
