Cyprodinil-d5is the deuterium labeledCyprodinil. Cyprodinil is an anilinopyrimidine broad-spectrum fungicide that inhibits the biosynthesis of methionine in phytopathogenic fungi. Cyprodinil inhibits mycelial cell growth of B. cinerea, P. herpotrichoides, and H. oryzae on amino acid-free media (IC50s=0.44, 4.8, and 0.03 μM, respectively). Cyprodinil acts as an androgen receptor (AR) agonist (EC50=1.91 μM) in the absence of the AR agonist DHT and inhibits the androgenic effect of DHT (IC50=15.1 μM).
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].
