TRANSPORTERS AND DRUG-METABOLIZING ENZYMES IN DRUG TOXICITY Explore up-to-date coverage on the interaction between drug metabolism enzymes, transporters, and drug toxicity with this leading resources Transporters and Drug-Metabolizing Enzymes in Drug Toxicity delivers a comprehensive and updated review of the relationship between drug metabolism, transporters, and toxicity, providing insights into a major challenge in drug development – accurate assessment of human drug toxicity. Combining two disciplines frequently considered independently of one another, the book combines drug metabolism and toxicology with a focus on the role of biotransformation on drug toxicity and as a major factor for species and individual differences. Mechanism and species differences in drug metabolizing enzymes and transporters are discussed, as are the methods used to investigate the role of drug metabolizing enzymes and transporters in drug toxicity. Finally, the distinguished authors describe promising new experimental approaches to accurately assessing human drug toxicity via the consideration of human-specific drug metabolism in toxicity assays. In addition to topics as diverse as extended clearance models, experimental approaches for the estimation of DILI potential of drug candidates and roles of transporters in renal drug toxicity, readers will also enjoy the inclusion of such subjects as: A thorough overview of and introduction to drug metabolism and transporters and drug toxicity An exploration of drug metabolism enzymes and transporter activities as risk factors of marketed drugs associated with drug-induced fatalities A discussion of human-based in vitro experimental models for the evaluation of metabolism-dependent drug toxicity A treatment of mechanism-based experimental models for the evaluation of BSEP inhibition and DILI An examination of transporters and cochlea toxicity Perfect for scientists, students, and practitioners with interests in metabolism, toxicology, and drug development in the pharmaceutical industry, Transporters and Drug-Metabolizing Enzymes in Drug Toxicity will also earn a place in the libraries of medicinal chemists, pharmacologists, biochemists, toxicologists, and regulators in the pharmaceutical and health industries.

Drug metabolism and transport are very important facets within the discipline of pharmaceutical sciences, with enzyme kinetic concepts utilized regularly in characterizing and modeling the disposition and elimination of drugs. Enzyme Kinetics in Drug Metabolism: Fundamentals and Applications focuses on very practical aspects of applying kinetic principles to drug metabolizing enzymes and transporters. Divided into five convenient sections, topics include the fundamental principles of enzyme kinetics, the kinetics of oxidative and conjugative drug metabolizing enzymes and drug transporters, modeling approaches for both drug metabolizing enzymes and transporters including novel systems biology approaches, understanding of variability both experimental and interindividual (pharmacogenomic), and case studies that provide real life examples of applying these principles. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics especially suitable for the novice, in some cases step-by-step, readily reproducible protocols, and insights to help with troubleshooting and avoiding known pitfalls with extensive cross referencing to assist in learning. Authoritative and easily accessible, Enzyme Kinetics in Drug Metabolism: Fundamentals and Applications serves as a very practical teaching tool for novice, non-mathematically trained scientists interested in these fundamental concepts and as an aid for their supervisors in teaching these principles.

A practice-oriented desktop reference for medical professionals, toxicologists and pharmaceutical researchers, this handbook provides systematic coverage of the metabolic pathways of all major classes of xenobiotics in the human body. The first part comprehensively reviews the main enzyme systems involved in biotransformation and how they are orchestrated in the body, while parts two to four cover the three main classes of xenobiotics: drugs, natural products, environmental pollutants. The part on drugs includes more than 300 substances from five major therapeutic groups (central nervous system, cardiovascular system, cancer, infection, and pain) as well as most drugs of abuse including nicotine, alcohol and "designer" drugs. Selected, well-documented case studies from the most important xenobiotics classes illustrate general principles of metabolism, making this equally useful for teaching courses on pharmacology, drug metabolism or molecular toxicology. Of particular interest, and unique to this volume is the inclusion of a wide range of additional xenobiotic compounds, including food supplements, herbal preparations, and agrochemicals.

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.
