General description

The chiral carbon at position 9 produces two enantiomers, R- and S-warfarin. Commercially available warfarin (Coumadin or Jantoven) is a racemic mixture of S- and R-enantiomers.

Application

(R)-(+)-warfarin has been used to investigate whether enantiomers of warfarin stereoselectively interact with pregnane X nuclear receptor (PXR) to upregulate main drug/xenobiotic-metabolizing enzymes cytochrome P450 3A4 (CYP3A4) and cytochrome P450 2C9 (CYP2C9). It has also been used in HepG2 cells to study protein profiles

Biochem/physiol Actions

Warfarin acts as a vitamin K antagonist. It is widely used to treat thromboembolic disorders. (R)-warfarin interacts with pregnane X receptor (PXR) and induces cytochrome P450 3A4 (CYP3A4) and CYP2C9 mRNAs expression in primary human hepatocyte cultures.
CYP1A2/3A4 substrate; anticoagulant.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Preparation Note

(+)-Warfarin is soluble in DMF, DMSO and ethanol.
