Valdecoxib-d₃  (Synonyms: SC 65872-d₃)

Valdecoxib-d₃ is the deuterium labeled Valdecoxib. Valdecoxib is a highly potent and selective inhibitor of COX-2, with IC50s of 5 nM and 140 μM for COX-2 and COX-1, respeceively. Valdecoxib can be used in the research of arthritis and pain[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].
