1. Introduction of 4-Hydroxycoumarin

The 4-Hydroxycoumarins are a class of vitamin K antagonist (VKA) anticoagulant drug molecules derived from coumarin (chromen-2-one) by adding a hydroxy group at the 4 position to obtain "4-hydroxycoumarin" (or "4-hydroxychromen-2-one"; formally then renumbered as 2-hydroxychromen-4-one), then adding a large aromatic substituent at the 3-position (the ring-carbon between the hydroxyl and the carbonyl). The large 3-position substituent is required for anticoagulant activity.

4. Application of 4-Hydroxycoumarin

The synthetic drugs in the 4-hydroxycoumarin class are all noted primarily for their use as anticoagulants, though they can have several additional effects. All affect the normal metabolism of vitamin K in the body by inhibiting the enzyme vitamin K epoxide reductase which recycles vitamin K to active form. As such, these compounds form the most important and widely used subset of vitamin K antagonist drugs, but other such drugs exist which do not have the 4-hydroxycoumarin structure. All the vitamin K antagonist agents diminish the amount of available vitamin K in the body, and thus inhibit the action of vitamin K-dependent enzymes that are critically involved in the production of active forms of certain clotting factors, and certain other metabolic processes involving the binding of calcium ion.
