Useful:

• Uses: (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 The R-(+)-form of Warfarin (W498500). Coumarin anticoagulant.
