Biochemistry Of Drug Metabolizing Enzymes

Biochemistry of Drug Metabolizing Enzymes: Trends and Challenges is a complete and well-integrated reference on their mechanisms of action, their role in diseases, agents responsible for their deactivation, and their malfunction. Chapters explain the biochemistry of DMEs, including biochemical activation, functions, computational approaches, different contaminants on the action and function of DMEs, and describe the importance of DMEs in the drug development process. Conditions covered include metabolic diseases, cardiovascular diseases, neurological diseases, physiological diseases, xenobiotics and inflammatory responses, and their contribution in the malfunctioning of drug metabolizing enzymes. This book is the perfect resource for pharmacology and biochemistry researchers to understand the principles of DMEs. Researchers in the corporate environment will also benefit from the comprehensive list of diseases associated with malfunction of DMEs. Includes extensive classification of DMEs, their mechanism of action and computational analysis Covers the biotransformation of drug by DMEs and the possible impact of environmental contaminants Discusses the activity of DMEs in different clinical conditions such as cardiovascular disease, metabolic disorders, inflammation and neurotoxicity Includes modern and novel bioanalytical techniques to predict the effect of DMEs

Although the scientific literature on drug metabolism is extensive, it suffers from the disadvantage that the material is diffuse and consists largely of specialist monographs dealing with particular aspects of the subject. In addi tion, although there are a few excellent texts on drug metabolism in print, these tend to be earlier publications and hence do not take into account the many recent advances in this area. Our motivations for writing this book therefore arose from the clear need for a recent and cohesive introductory text on this subject, specifically designed to cater for the needs of undergraduate and postgraduate students. Much of the subject matter in this text is derived from various courses on drug metabolism given at the University of Surrey and the University of Glasgow to basic science students in pharmacology, biochemistry, nutrition and nursing studies, to pre-clinical medical students and to under graduate and post-graduate students in toxicology. Therefore, it is our inten tion that this text will serve as a primer in drug metabolism to a variety of students in the life sciences taking courses in this subject. The term 'drug metabolism' in its broadest sense may be considered as the absorption, distribution, biotransformation and excretion of drugs. To cover all these facets of drug metabolism in a single text is a voluminous task and therefore we have focused primarily on the biotransformation aspects of the subject.

Drug Metabolism: Current Concepts provides a comprehensive understanding of the processes that take place following ingestion of a medicinal agent or xenobiotic, with an emphasis on the crucial role of metabolism (biotransformation). How a sound knowledge of these phenomena is incorporated into the design of effective new drug candidates is also explained. The user-friendly text focuses on concepts rather than extraneous details and is supported by many illustrated examples of biotransformations as well as frequent references to current critical reviews and articles highlighting the nature of research objectives in this vibrant area of medicinal development. The final topic on strategies for drug design relies on the background provided by the rest of the book. This book is ideally suited as an advanced text for courses in drug metabolism for students of medicine, pharmacy, pharmacology, biochemistry; and for courses in drug design and drug delivery for students of medicinal chemistry. It is also appropriate for professional seminars or courses that relate to the fate of a drug in the body, drug interactions, adverse reactions and drug design.

Identification and Quantification of Drugs, Metabolites, Drug Metabolizing Enzymes, and Transporters, Second Edition, is completely updated to provide an overview of the last decade's numerous advances in analytical technologies for detection and quantification of drugs, metabolites, and biomarkers. This new edition goes beyond LC-MS and features all-new chapters on how to evaluate drug absorption, distribution, metabolism, and excretion, potential for hepatic and renal toxicity, immunogenicity of biotherapeutics and translational tools for predicting human dosage, safety and efficacy of small molecules and biologics. This book will be an important handbook and desk reference for pharmacologists, toxicologists, clinical scientists, and students interested in the fields of pharmacology, biochemistry, and drug metabolism. Four sections in the book with 24 chapters give readers an overview of state-of-the-art techniques for identifying and quantifying drugs, metabolites and biomarkers, including a chapter on new approaches for quantification of enzymes and transporters in different tissues Focuses on the role of drug metabolism enzymes, transporters in disposition and drug-drug interactions, as well as strategies for evaluating drug metabolism and safety using advanced liver and kidney models. Discussions on immunogenicity risks of biologics and their evaluation methods have been included Includes several chapters on advanced translational sciences to predict human dosage, pharmacokinetics and efficacy for small molecules and biotherapeutics All chapters are written by experts with a wide range of practical experience from the industry and academia

Offering a conceptual and factual presentation of the metabolism of drugs and other xenobiotics, these two volumes distinctly focus on the biochemistry, with an emphasis on xenobiotic-metabolizing enzymes, their reactions and regulations. The first volume is divided into three parts. Part One begins by introducing xenobiotics in the broad context of physiological metabolism, and continues with an overview of the processes of drug disposition and metabolism. It then goes on to summarize the macroscopic and microscopic locations of drug ...

Presented here are recent advances in biochemical, toxicological, and regulatory aspects of oxidative drug metabolizing enzymes. Mainly cytochrome P450-dependent and flavin-containing monooxygenases (FMO) are covered. Moreover, the book deals with genotoxicity studies and toxicological interactions of environmental chemicals and mechanisms of mutagenicity and tumor formation. The construction of genetically engineered mammalian cells for the production of a specific P450 isozyme and the application of these cell lines in drug metabolism, mutagenicity and toxicity studies are described in detail. Further, insight is provided into how a number of aquatic species cope with pollutants and their genotoxicity.

Critical in the elimination of drugs and other xenobiotics from the body, cytochrome P450 has strong bearing on scientific assessments of genetic polymorphism in metabolism, possible drug-drug interactions, and bioavailability of candidate drugs. This text systematizes findings on P450 and similar enzymes - as well as parallel issues shaping the pharmaceutical industry - to promote the next generation of safer, more effective drugs.
