PW064566 View Pathway	metabolic Vitamin K Metabolism Mus musculus Vitamin K describes a group of lipophilic, hydrophobic vitamins that exist naturally in two forms (and synthetically in three others): vitamin K1, which is found in plants, and vitamin K2, which is synthesized by bacteria. Vitamin K is an important dietary component because it is necessary as a cofacter in the activation of vitamin K dependent proteins. Metabolism of vitamin K occurs mainly in the liver. In the first step, vitamin K is reduced to its quinone form by a quinone reductase such as NAD(P)H dehydrogenase. Reduced vitamin K is the form required to convert vitamin K dependent protein precursors to their active states. It acts as a cofactor to the integral membrane enzyme vitamin K-dependent gamma-carboxylase (along with water and carbon dioxide as co-substrates), which carboxylates glutamyl residues to gamma-carboxy-glutamic acid residues on certain proteins, activating them. Each converted glutamyl residue produces a molecule of vitamin K epoxide, and certain proteins may have more than one residue requiring carboxylation. To complete the cycle, the vitamin K epoxide is returned to vitamin K via the vitamin K epoxide reductase enzyme, also an integral membrane protein. The vitamin K dependent proteins include a number of important coagulation factors, such as prothrombin. Thus, warfarin and other coumarin drugs act as anticoagulants by blocking vitamin K epoxide reductase.

PW128158 View Pathway	drug action Vorapaxar Action Pathway Homo sapiens Vorapaxar also known as Zontivity, is an inhibitor for platelet aggregation used to treat patients with a history of myocardial infarction or peripheral arterial disease to reduce the chance of thrombotic cardiovascular events. Vorapaxar inhibits protease-activated receptor 1 (PAR-1), which is a G protein-coupled receptor that is expressed on the platelet. Inhibition of PAR-1 prevents platelet aggregation and activation. Vorapaxar is administered orally and rapidly absorbs and travels through the bloodstream. It is metabolized to major metabolites M20 and M19 by CYP3A4 and CYP2J2. This is then eliminated primarily through feces and urine. Due to the anticoagulant and antiplatelet nature, herbs and supplements with similar activity should be avoided such as garlic, ginger, bilberry, danshen, piracetam and ginkgo biloba. St.John's Wort should also be avoided as it induces CYP3A metabolism and will reduce the concentration of Vorapaxar. Caution should be exercised with grapefruit products, as coadministration with strong inhibitors should be avoided.
