Coumarin drugs

Warfarin, sold under the brand name Coumadin among others, is used as an anticoagulant medication. It is commonly used to prevent deep vein thrombosis and pulmonary embolism, and to protect against stroke in people who have atrial fibrillation, valvular heart disease, or artificial heart valves. Warfarin may sometimes be prescribed following a ST-segment elevation myocardial infarction and orthopedic surgery. It is usually taken by mouth, but may also be administered intravenously.

Acenocoumarol is an anticoagulant that functions as a vitamin K antagonist (like warfarin). It is a derivative of coumarin and is generic, so is marketed under many brand names worldwide.

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.

Brodifacoum is a highly lethal 4-hydroxycoumarin vitamin K antagonist anticoagulant poison. In recent years, it has become one of the world's most widely used pesticides. It is typically used as a rodenticide, but is also used to control larger pests such as possums.

Phenprocoumon (marketed under the brand names Marcoumar, Marcumar and Falithrom) is a long-acting anticoagulant to be taken by mouth, and a coumarin derivative. It acts as a vitamin K antagonist and inhibits blood clotting (coagulation) by blocking synthesis of coagulation factors II, VII, IX and X. It is used for the prophylaxis and treatment of thromboembolic disorders such as heart attacks and pulmonary (lung) embolism. The most common adverse effect is bleeding. The drug interacts with a large number of other medications, including aspirin and St John's Wort. It is the standard coumarin us

Novobiocin, also known as albamycin, is an aminocoumarin antibiotic that is produced by the actinomycete Streptomyces niveus, which is a heterotypic synonym for S. spheroides a member of the class Actinomycetia. Other aminocoumarin antibiotics include clorobiocin and coumermycin A1. Novobiocin was first reported in the mid-1950s (then called streptonivicin).

Coumaphos is a nonvolatile, fat-soluble phosphorothioate with ectoparasiticide properties: it kills insects and mites. It is well known by a variety of brand names as a dip or wash, used on farm and domestic animals to control ticks, mites, flies and fleas.

Coumatetralyl is an anticoagulant of the 4-hydroxycoumarin vitamin K antagonist type used as a rodenticide.

Antidote Vitamin K1.]] 4-Hydroxycoumarins are a class of vitamin K antagonist (VKA) anticoagulant drug molecules. Chemically, they are derived from coumarin by adding a hydroxy group at the 4 position to obtain 4-hydroxycoumarin, then adding a large aromatic substituent at the 3-position (the ring-carbon between

Hymecromone (4-methylumbelliferone) is a drug used in bile therapy. It is used as choleretic and antispasmodic drugs and as a standard for the fluorometric determination of enzyme activity.

thumb|Skeletal formula of [[novobiocin]] Aminocoumarin is a class of antibiotics that act by an inhibition of the DNA gyrase enzyme involved in the cell division in bacteria. They are derived from Streptomyces species, whose best-known representative – Streptomyces coelicolor – was completely sequenced in 2002. The aminocoumarin antibiotics include: Novobiocin, Albamycin (Pharmacia And Upjohn) Coumermycin Clorobiocin

Tioclomarol is an anticoagulant of the 4-hydroxycoumarin vitamin K antagonist type. It is a second generation drug, used as a rodenticide that is effective for the control of rodents that are resistant to this class of drugs.

Ensaculin (KA-672) is a drug from the coumarin family, which has been researched as a potential treatment for dementia. It acts on a number of receptor systems, being both a weak NMDA antagonist and a 5HT1A agonist. Animal studies have shown promising nootropic effects, although efficacy in humans has yet to be proven. It was well tolerated in human trials, with the main side effect being orthostatic hypotension (low blood pressure upon standing).

Batoprazine is a drug of the phenylpiperazine class which has been described as a serenic or antiaggressive agent. It acts as a 5-HT1A and 5-HT1B receptor agonist. It is closely related to eltoprazine, fluprazine, and naphthylpiperazine, of which possess similar actions and effects.

Carbocromen (chromonar) is a vasodilator. It was used as a coronary dilator between 1963 and 1966.
