Vanzacaftor-d₄  (Synonyms: VX-121-d₄)

Vanzacaftor-d₄ (VX-121-d₄) is the deuterium labeled Vanzacaftor (HY-145603). Vanzacaftor is an orally active noval corrector of Cystic fibrosis transmembrane conductance regulator (CFTR). Vanzacaftor improves processing and trafficking of CFTR protein as well as increases chloride transport in triple combined with Tezacaftor (HY-15448) and Deutivacaftor. Vanzacaftor-Tezacaftor-Deutivacaftor is safe and well tolerated, improving lung function, respiratory symptoms, and CFTR function with cystic fibrosis, which is promising for research in the field of cystic fibrosis diseases^[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.

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