(R)-Acenocoumarol

(R)-Acenocoumarol R)-Acenocoumarin; (R)-Nicoumalone) is a short-acting and orally active anticoagulant, like Warfarin (HY-B0687), works by inhibiting vitamin K epoxide reductase. (R)-Acenocoumarol has a greater in vivo anticoagulant potency than Warfarin. (R)-Acenocoumarol has a single chiral center that produces two different enantiomeric forms. (R)-Acenocoumarol has a longer plasma elimination half-life (6.6 h) and a slower plasma clearance rate (1.9 L/h) than the (S)-enantiomer, resulting in a stronger in vivo anticoagulant effect.
