rel-Ritonavir-d₆  (Synonyms: rel-ABT 538-d₆; rel-RTV-d₆)

rel-Ritonavir-d₆ (rel-ABT 538-d₆; rel-RTV-d₆) is the deuterium labeled Ritonavir (HY-90001). Ritonavir (ABT 538) is an inhibitor of HIV protease used to treat HIV infection and AIDS. Ritonavir is also a SARS-CoV 3CLpro inhibitor with an IC₅₀ of 1.61 μM^[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].
