Tolbutamide methyl hydroxylation and S-warfarin 7-hydroxylation activities were reconstituted in systems containing recombinant human cytochrome P450 (P450 or CYP) 2C10(2C9) and the optimal conditions for the systems were compared with those of bufuralol 1'-hydroxylation by CYP1A1, theophylline 8-hydroxylation by CYP1A2, bufuralol 1'-hydroxylation by ...

Current Drug Metabolism, 2009
The term fatty liver identifies a liver in which lipids account for more than 5% of the liver's wet weight. When fat accumulates, the lipids primarily stored as triglycerides (TG) result in steatosis and provide substrates for lipid peroxidation. Accumulation of neutral lipids in hepatocytes leads to micro- and macro-vesicular steatosis and to balloon ...

Current Opinion in Structural Biology, 1995
Since 1993, three new cytochrome P450 X-ray structures have been determined, giving a total of four known structures. Two of the new structures are in the substrate-free form and one is substrate-bound. These new structures, together with a wealth of mutagenesis studies on various P450s, have provided considerable information on what structural ...

SAR and QSAR in Environmental Research, 2001
This paper describes a specialized database dedicated exclusively to the cytochrome P450 superfamily. The system provides the impression of superfamily's nomenclature and describes structure and function of different P450 enzymes. Information on P450-catalyzed reactions, substrate preferences, peculiarities of induction and inhibition is available ...

Since the last review of this topic, further insight has been gained into the presence and functions of cytochrome P450 proteins in the hepatopancreas and other organs of aquatic crustacean species, although progress has been slow relative to the advances in other species.

Current Protocols in Pharmacology, 2001
AbstractCytochrome P450s (CYPs) play a major role in drug detoxification, and inhibition of CYP‐mediated metabolism may lead to accumulation of toxic drug levels in the plasma. To prevent adverse drug‐drug interactions, new drug candidates are routinely tested for their ability to inhibit these enzymes.

Pharmacogenetics of the Cytochromes P450
Current Topics in Medicinal Chemistry, 2004The cytochromes P450 are a family of heme-containing proteins with a major role in the oxidation of both xenobiotics (including prescribed drugs) and endogenous compounds. There are at least 57 human P450s (termed isoforms) which are all encoded by separate genes but only 10 of these contribute to drug metabolism, with the major contribution coming ...

Cytochrome P450 in trypanosomatids
Biochemical Pharmacology, 1993Post-mitochondrial supernatant extracts prepared from bloodstream forms of Trypanosoma brucei brucei, T. cruzi epimastigotes, Leishmania donovani promastigotes and Crithidia fasciculata have been found to catalyse cytochrome P450-dependent reactions. Appreciable ethoxycoumarin deethylase and ethoxyresorufin deethylase activities were found in all of ...

Humans and rodents are exposed to many foreign compounds in their diet (e.g., herbal supplements such as St. John's wart), in their environment (e.g., organochlorine pesticides and polychorinated biphenyls), and as clinically prescribed drugs (e.g., rifampin and phenobarbital).

Induction of Cytochrome P450s by Rutaecarpine and Metabolism of Rutaecarpine by Cytochrome P450s
Planta Medica, 2004Rutaecarpine is an alkaloid originally isolated from the unripe fruit of Evodia rutaecarpa. Recently, rutaecarpine has been characterized to have an anti-inflammatory activity through cyclooxygenase-2 inhibition. In the present studies, the effects of rutaecarpine on liver cytochrome P450 s (P450s) and P450 s involved in the metabolism of rutaecarpine ...
