Cytochrome P450 inhibitors is a category of agents that inhibit Cytochrome P450. Subcategories. This category has the following 8 subcategories, out of 8 total. A.
Cytochrome P450 3A4 (abbreviated CYP3A4) (EC 1.14.13.97) is an important enzyme in the body, mainly found in the liver and in the intestine, which in humans is encoded by CYP3A4 gene. It oxidizes small foreign organic molecules ( xenobiotics ), such as toxins or drugs, so that they can be removed from the body.
Watercress is also a known inhibitor of the cytochrome P450 CYP2E1, which may result in altered drug metabolism for individuals on certain medications (e.g., chlorzoxazone). [ 18 ] Tributyltin inhibits cytochrome P450, leading to masculinization of mollusks.
A second electron is transferred, from either cytochrome P450 reductase, ferredoxins, or cytochrome b 5, reducing the Fe-O 2 adduct to give a short-lived peroxo state. The peroxo group formed in step 4 is rapidly protonated twice, releasing one molecule of water and forming the highly reactive species referred to as P450 Compound 1 (or just ...
Cytochrome P450 2C19 (abbreviated CYP2C19) is an enzyme protein. It is a member of the CYP2C subfamily of the cytochrome P450 mixed-function oxidase system. This subfamily includes enzymes that catalyze metabolism of xenobiotics , including some proton pump inhibitors and antiepileptic drugs.
Cimetidine is a potent inhibitor of certain cytochrome P450 (CYP) enzymes, [20] [32] including CYP1A2, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and CYP3A4. [20] [32] [33] The drug appears to primarily inhibit CYP1A2, CYP2D6, and CYP3A4, [34] of which it is described as a moderate inhibitor. [8]
