Cytochrome P450 Protocols by Ian R. Phillips,Elizabeth A. Shephard,Paul R. Ortiz de Montellano Pdf

Cytochromes P450 (CYPs) comprise a large superfamily of proteins that are of central importance in the detoxification or activation of a tremendous number of natural and synthetic hydrophobic xenobiotics, including many therapeutic drugs, chemical carcinogens and environmental pollutants. CYPs are important in mediating interactions between an organism and its chemical environment and in the regulation of physiological processes. Cytochrome P450 Protocols, Third Edition focuses on high-throughput methods for the simultaneous analysis of multiple CYPs, substrates or ligands. Although the emphasis is on CYPs of mammalian origin, it reflects an increasing interest in CYPs of bacterial species. Also included are chapters on cytochrome P450 reductase (the redox partner of CYPs) and the flavin-containing monooxygenases (FMOs), and metabolomic and lipidomic approaches for identification of endogenous substrates of CYPs (‘de-orphanizing’ CYP substrates). Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Cytochrome P450 Protocols, Third Edition provides a wide range of techniques accessible to researchers in fields as diverse as biochemistry, molecular biology, pharmacology, toxicology, environmental biology and genetics.

Cytochromes P450: Drug Metabolism, Bioactivation and Biodiversity 2.0 by Patrick M. Dansette,Daniéle Werck-Reichhart Pdf

This book, "Cytochromes P450: Drug Metabolism, Bioactivation and Biodiversity", presents five papers on human cytochrome P450 (CYP) and P450 reductase, three reviews on the role of CYPs in humans and their use as biomarkers, six papers on CYPs in microorganisms, and one study on CYP in insects. The first paper reports the in silico modeling of human CYP3A4 access channels. The second uses structural methods to explain the mechanism-based inactivation of CYP3A4 by mibefradil, 6,7-dihydroxy-bergamottin, and azamulin. The third article compares electron transfer in CYP2C9 and CYP2C19 using structural and biochemical methods, and the fourth uses kinetic methods to study electron transfer to CYP2C8 allelic mutants. The fifth article characterizes electron transfer between the reductase and CYP using in silico and in vitro methods, focusing on the conformations of the reductase. Then, two reviews describe clinical implications in cardiology and oncology and the role of fatty acid metabolism in cardiology and skin diseases. The second review is on the potential use of circulating extracellular vesicles as biomarkers. Five papers analyze the CYPomes of diverse microorganisms: the Bacillus genus, Mycobacteria, the fungi Tremellomycetes, Cyanobacteria, and Streptomyces. The sixth focuses on a specific Mycobacterium CYP, CYP128, and its importance in M. tuberculosis. The subject of the last paper is CYP in Sogatella furcifera, a plant pest, and its resistance to the insecticide sulfoxaflor.

Cytochrome P450 2E1: Its Role in Disease and Drug Metabolism by Aparajita Dey Pdf

The book deals with various clinical aspects of cytochrome P450 2E1 (CYP2E1) which is a potent source for oxidative stress. Oxidative stress is critical for pathogenesis of diseases and CYP2E1 is a major contributor for oxidative stress. Several clinical disorders are associated with changes in regulation of CYP2E1 and the consequent abnormalities which include alcoholic liver disease, alcoholic pancreatitis, carcinogenesis, non-alcoholic fatty liver disease, non-alcoholic steatohepatitis, obesity, hepatitis C virus infection, reproductive organ toxicity, hepatocellular and cholestatic liver cirrhosis, inhibition of bone repair, cross-tolerance in smokers and people treated with nicotine, disorders of central nervous system, changes in metabolism of protoxicants in the circulatory system and susceptibility to human papillomavirus infection. Hence, CYP2E1 emerges as a new and potent player in aggravating injury and furthering disease complications.

Guide to Cytochromes P450 by David F. V. Lewis Pdf

Cytochromes are coloured iron-containing proteins that transfer electrons during cellular respiration and photosynthesis. The Cytochrome P450 family of enzymes catalyze reactions whereby water-insoluble drugs or metabolites, that would otherwise reach toxic levels in cell membranes, are rendered suitably water-soluble to leave the cell and be excreted in the urine. Due to the extensive nature of this subject, which is an area of intense scientific interest, the field is rapidly advancing and there is a need for new textbooks to keep abreast of the latest developments. The book fulfils that role in providing a fast-track approach for those coming into the P450 field, either at postgraduate level or in particular within the pharmaceutical industry. A Guide to Cytochrome P450 Structure and Function acts as an adjunct to the previous book Cytochromes P450: Structure, Function and Mechanism. It reviews the current status of the P450 field in terms of our present knowledge and understanding of the enzymes structure and function, including their multiplicity of forms, diversity of substrates, and selectivity. This is brought together with the latest research topics, including pharmacogenetics, regulation, human DMEs, toxicity screening and molecule modeling, to provide a fast-track approach for those new to the field.

Flavoprotein Protocols by Steven K. Chapman,Graeme A. Reid Pdf

As a scientist with an interest in proteins you will, at some time in your career, isolate an enzyme that turns out to be yellow—or perhaps you already have. Alternatively, you may identify a polypeptide sequence that is related to known flavin-containing proteins. This may, or may not, be your first encounter with flavoproteins. However, even if you are an old hand in the field, you may not have exploited the full range of experimental approaches applicable to the study of flavoproteins. We hope that Flavoprotein Protocols will encourage you to do so. In this volume we have sought to bring together a range of experimental methods of value to researchers with an interest in flavoproteins, whether or not these researchers have experience in this area. A broad range of techniques, from the everyday to the more specialized, is described by scientists who are experts in their fields and who have ext- sive practical experience with flavoproteins. The wide range of approaches, from wet chemistry to dry computation, has, as a consequence, demanded a range of formats. Where appropriate (particularly for analytical methods) the protocol described is laid out in easy-to-follow steps. In other cases (e. g. , the more advanced spectroscopies and computational methods) it is far more apt to describe the general approach and relevance of the methods. We hope this wide-ranging approach will sow the seeds of many future collaborations - tween laboratories and further our knowledge and understanding of how f- voproteins work.
