Adefovir-d₄  (Synonyms: GS-0393-d₄; PMEA-d₄)

Adefovir-d₄ is the deuterium labeled Adefovir. Adefovir (GS-0393) is an adenosine monophosphate analog antiviral agent that after intracellular conversion to Adefovir diphosphate inhibits HBV DNA polymerase. Adefovir has an IC50 of 0.7 μM against HBV in the HepG2.2.15 cell line. Adefovir has good antiviral activity against several viruses, including HBV and herpesviruses[1][2][3].

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].
