Cytochrome P4502C8 (CYP2C8) is a member of thecytochrome P450 mixed-function oxidase system involved in the metabolism ofxenobiotics in the body. Cytochrome P4502C8 also possessesepoxygenase activity, i.e. it metabolizes long-chainpolyunsaturated fatty acids, e.g.arachidonic acid,eicosapentaenoic acid,docosahexaenoic acid, andlinoleic acid to their biologically activeepoxides.[5]

Ligands

[edit]

Following is a table of selectedsubstrates,inducers andinhibitors of 2C8.

Inhibitors of CYP2C8 can be classified by theirpotency, such as:

  • Strong inhibitor being one that causes at least a five-fold increase in the plasmaAUC values, or more than 80% decrease inclearance.[6]
  • Moderate inhibitor being one that causes at least a two-fold increase in the plasma AUC values, or 50-80% decrease in clearance.[6]
  • Weak inhibitor being one that causes at least a 1.25-fold but less than two-fold increase in the plasma AUC values, or 20-50% decrease in clearance.[6]

Epoxygenase activity

[edit]

CYP2C8 also possessesepoxygenase activity: it is one of the principal enzymes responsible for attacking various long-chain polyunsaturated fatty acids at their double (i.e.alkene) bonds to formepoxide products that act as signaling agents. It metabolizes:1)arachidonic acid to variousepoxyeicosatrienoic acids (also termed EETs);2)linoleic acid to 9,10-epoxy octadecenoic acids (also termedvernolic acid, linoleic acid 9:10-oxide, or leukotoxin) and 12,13-epoxy-octadecenoic (also termedcoronaric acid, linoleic acid 12,13-oxide, or isoleukotoxin);3)docosahexaenoic acid to variousepoxydocosapentaenoic acids (also termed EDPs); and4)eicosapentaenoic acid to various epoxyeicosatetraenoic acids (also termed EEQs).[9][10][11]

Along with CYP2C8,CYP2C9,CYP2C19,CYP2J2, and possiblyCYP2S1 are the main producers of EETs and, very likely, EEQs, EDPs, and the epoxides of linoleic acid.[12][13]
