Deucravacitinib-¹³C,d₃ 

Deucravacitinib-¹³C,d₃ is the ¹³C- and deuterium labeled Deucravacitinib. Deucravacitinib (BMS-986165) is a highly selective, orally bioavailable allosteric TYK2 inhibitor for the treatment of autoimmune diseases, which selectively binds to TYK2 pseudokinase (JH2) domain (IC₅₀=1.0 nM) and blocks receptor-mediated Tyk2 activation by stabilizing the regulatory JH2 domain. Deucravacitinib inhibits IL-12/23 and type I IFN pathways. Deucravacitinib, the FDA's world first de novo deuterium, is available for study in moderate to severe plaque psoriasis^[1][2].

1. This compound can be used as a tracer.
2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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.

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
