(R)-(+)-Warfarin
Based on 1 Customer Validation
(R)-(+)-Warfarin is an orally active chiral 4-hydroxycoumarin compound with vitamin K epoxide reductase (VKOR) inhibitory activity and cytochrome P450 substrate activity. (R)-(+)-Warfarin undergoes stereoselective metabolism via CYP1A2 to form 6-Hydroxywarfarin and 8-Hydroxywarfarin, and is metabolized via CYP3A4 to produce 10-Hydroxywarfarin (HY-134999). (R)-(+)-Warfarin can be used for the research of thromboembolic diseases.

Biological Activity

CYP1A2 |
CYP3A4 |
(R)-(+)-Warfarin acts as a stereoselective substrate for polymorphic recombinant human CYP450 enzymes. Wild-type CYP1A1 and its Ile462 and Val462 mutants, as well as CYP1A2, respectively catalyze the 6/8-hydroxylation of (R)-(+)-Warfarin, exhibiting differential regioselectivity and Km values. CYP2C19 mediates 8-hydroxylation but shows low expression in the liver, while CYP3A4, which has high hepatic abundance, catalyzes 10-hydroxylation and serves as the major metabolic enzyme in vivo[1].
(R)-(+)-Warfarin competitively inhibits CYP2C9-mediated metabolism of S-Warfarin in human liver microsomes, with a Ki value of 6-6.9 μM; additionally, it is stereoselectively reduced by NADPH-dependent carbonyl reductases in human liver and kidney to form R,S-warfarin alcohol, and the cytosolic enzyme fraction accounts for the majority of the reductive activity[1].
(R)-(+)-Warfarin inhibits vitamin K reductase and vitamin K1 epoxide reductase in Wistar rat liver microsomes; it is metabolized by cytochrome P-450 enzymes into multiple oxidative metabolites in human liver microsomes[2].
(R)-(+)-Warfarin binds extensively to human serum albumin, and its binding affinity is lower than that of (S)-warfarin[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
(R)-(+)-Warfarin (daily; from 2 days pre-implant until study end) does not inhibit primary tumour growth or lung metastasis in mice bearing Lewis lung carcinoma, and does not produce measurable anticoagulant effects in this model[2].
(R)-(+)-Warfarin produces a longer-lasting anticoagulant response in rabbits than (S)-warfarin, even though it is less potent on a plasma concentration basis[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1.25 mg/mL (4.05 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1.25 mg/mL (4.05 mM); Clear solution
This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
