Curator's Comment: https://www.ncbi.nlm.nih.gov/mesh/68001728

Dicumarol is an coumarin-like compound found in sweet clover. It is used as oral anticoagulant and acts by inhibiting the hepatic synthesis of vitamin K-dependent coagulation factors (prothrombin and factors VII, IX, and X). It results in decresed prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots. Dicumarol is also used in biochemical experiments as an inhibitor of reductases.
