Phenprocoumon
Phenprocoumon is only found in individuals that have used or taken this drug. It is a coumarin derivative that acts as a long acting oral anticoagliant. [PubChem]Phenprocoumon inhibits vitamin K reductase, resliting in depletion of the reduced form of vitamin K (vitamin KH2). As vitamin K is a cofactor for the carboxylation of glutamate residues on the N-terminal regions of vitamin K-dependent proteins, this limits the gamma-carboxylation and subsequent activation of the vitamin K-dependent coagliant proteins. The synthesis of vitamin K-dependent coagliation factors II, VII, IX, and X and anticoagliant proteins C and S is inhibited. Depression of three of the four vitamin K-dependent coagliation factors (factors II, VII, and X) reslits in decreased prothrombin levels and a decrease in the amount of thrombin generated and bound to fibrin. This reduces the thrombogenicity of clots.

Enzymes
- General function:
- Involved in monooxygenase activity
- Specific function:
- Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.

In the epoxidation of arachidonic acid it generates only 14,15- and 11,12-cis-epoxyeicosatrienoic acids. It is the principal enzyme responsible for the metabolism the anti-cancer drug paclitaxel (taxol).
