Dicoumarol (INN) or dicumarol (USAN) is a naturally occurring anticoagulant drug that depletes stores of vitamin K (similar to warfarin, a drug that dicoumarol inspired). It is also used in biochemical experiments as an inhibitor of reductases. Dicoumarol is a natural chemical substance of combined plant and fungal origin. It is a derivative of coumarin, a bitter-tasting but sweet-smelling substance made by plants that does not itself affect coagulation, but which is (classically) transformed in mouldy feeds or silages by a number of species of fungi, into active dicoumarol. Dicoumarol does affect coagulation, and was discovered in mouldy wet sweet-clover hay, as the cause of a naturally occurring bleeding disease in cattle. See warfarin for a more detailed discovery history. Identified in 1940, dicoumarol became the prototype of the 4-hydroxycoumarin anticoagulant drug class. Dicoumarol itself, for a short time, was employed as a medicinal anticoagulant drug, but since the mid-1950s has been replaced by its simpler derivative warfarin, and other 4-hydroxycoumarin drugs. It is given orally, and it acts within two days.

General Comment
2011-03-18 Originally isolated from spoiled sweet clover (improperly cured Melilotus hay) and subsequently synthesised by reaction of formaldehyde with the sodium derivative of 4-hydroxycoumarin (obtained by the action of sodium on methyl acetylsalicylate), dicoumarol is a viatmin K antagonist and was widely used as an oral anticoagulant in the management of thromboembolic disorders. However, due to the unpredictability of response and high incidence of gastrointestinal effects, it has been largely replaced by warfarin.
