General description

Warfarin is an antagonist of vitamin K. It is an oral coumarin anticoagulant.

Application

(S)-(−)-Warfarin has been used in cell cultures.
Studies using (R)-(+)-warfarin have reported that it can upregulate hepatic CYP3A4 and CYP2C. It has also been used in HepG2 cells to study protein profiles.

Biochem/physiol Actions

CYP2C9 substrate; anticoagulant.
Warfarin is used to regulate and inhibit thromboembolic disorders. The CYP2C9 (cytochrome P450 family 2 subfamily C member 9) protein plays a major role in the inactivation of potent S-warfarin.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Warfarin, an antagonist of vitamin K, is an oral coumarin anticoagulant widely used to control and prevent thromboembolic disorders. Warfarin is clinically available as a racemic mixture of R- and S-warfarin. The S-enantiomer has three to five times greater anticoagulation
Jing Bai et al.
Proteomics. Clinical applications, 4(10-11), 808-815 (2010-12-08)
warfarin is a commonly prescribed oral anticoagulant with narrow therapeutic index. It interferes with the vitamin K cycle to achieve anti-coagulating effects. Warfarin has two enantiomers, S(-) and R(+) and undergoes stereoselective metabolism, with the S(-) enantiomer being more effective.
