dicoumarol
Noun A synthetic anticoagulant compound originally derived from spoiled sweet clover. It functions by inhibiting the synthesis of vitamin K-dependent clotting factors in the blood, thereby preventing the formation of blood clots. Historically significant, it has been largely superseded by other medications in clinical use.
Dicoumarol is used as a specific medical term to refer to this particular anticoagulant drug. It is primarily encountered in historical, pharmacological, or biochemical contexts rather than in everyday conversation.
Examples - The discovery of dicoumarol followed the investigation of a hemorrhagic disease in cattle. - Dicoumarol was an important early oral anticoagulant but had a variable and unpredictable effect. - In the laboratory, researchers studied the mechanism by which dicoumarol inhibits the enzyme vitamin K epoxide reductase.
- Historical Context: The term is often used when discussing the history of anticoagulant therapy, marking a step between the discovery of the link between spoiled sweet clover and bleeding, and the development of more reliable drugs like warfarin.
- Biochemical Agent: In research, may be used as a specific inhibitor in studies of quinone metabolism and cellular redox processes, due to its action on DT-diaphorase (NQO1).
- Dicumarol: An alternative spelling for the same compound.
- Bishydroxycoumarin: A former chemical name for dicoumarol.
- Anticoagulant (noun): The general class of drugs to which dicoumarol belongs.
- Warfarin (noun): A later, more commonly used anticoagulant drug that largely replaced dicoumarol.
- Anticoagulant agent (general term)
- Blood thinner (informal, general term)
Note: There are no common idioms or phrasal verbs associated with this highly technical term.
-
an anticoagulant drug that has now been largely replaced by warfarin
