Rifampicin-d₄  (Synonyms: Rifampin-d₄; Rifamycin AMP-d₄)

Rifampicin-d₄ is the deuterium labeled Rifampicin. Rifampicin is a potent and broad spectrum antibiotic against bacterial pathogens. Rifampicin has anti-influenza virus activities.

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].
