Cyclosporin A acetate-d₄  (Synonyms: Cyclosporine A acetate-d₄; Ciclosporin A acetate-d₄; CsA acetate-d₄)

Cyclosporin A acetate-d₄ (Cyclosporine A acetate-d₄; Ciclosporin A acetate-d₄) is a deuterium labeled Cyclosporin A (HY-B0579)^[1]. Cyclosporin A (Cyclosporine A) is an immunosuppressant which binds to the cyclophilin and inhibits phosphatase activity of protein phosphatase 2B (PP2B/calcineurin) with an IC₅₀ of 5 nM^[2]. Cyclosporin A also inhibits CD11a/CD18 adhesion^[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].

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