Bortezomib-d₈  (Synonyms: PS-341-d₈; LDP-341-d₈; NSC 681239-d₈)

Bortezomib-d₈ is the deuterium labeled Bortezomib. Bortezomib (PS-341) is a reversible and selective proteasome inhibitor, and potently inhibits 20S proteasome (Ki=0.6 nM) by targeting a threonine residue. Bortezomib disrupts the cell cycle, induces apoptosis, and inhibits NF-κB. Bortezomib is the first proteasome inhibitor anticancer agent. Anti-cancer activity[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].
