Baloxavir-d5 is deuterium labeled Baloxavir. Baloxavir (Baloxavir acid), derived from the prodrug Baloxavir marboxil, is a first-in-class, potent and selective cap-dependent endonuclease (CEN) inhibitor within the polymerase PA subunit of influenza A and B viruses. Baloxavir inhibits viral RNA transcription and replication and has potently antiviral activity^[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].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
