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.
With the most comprehensive and up-to-date overview of structure-based drug discovery covering both experimental and computational approaches, Structural Biology in Drug Discovery: Methods, Techniques, and Practices describes principles, methods, applications, and emerging paradigms of structural biology as a tool for more efficient drug development. Coverage includes successful examples, academic and industry insights, novel concepts, and advances in a rapidly evolving field. The combined chapters, by authors writing from the frontlines of structural biology and drug discovery, give readers a valuable reference and resource that: Presents the benefits, limitations, and potentiality of major techniques in the field such as X-ray crystallography, NMR, neutron crystallography, cryo-EM, mass spectrometry and other biophysical techniques, and computational structural biology Includes detailed chapters on druggability, allostery, complementary use of thermodynamic and kinetic information, and powerful approaches such as structural chemogenomics and fragment-based drug design Emphasizes the need for the in-depth biophysical characterization of protein targets as well as of therapeutic proteins, and for a thorough quality assessment of experimental structures Illustrates advances in the field of established therapeutic targets like kinases, serine proteinases, GPCRs, and epigenetic proteins, and of more challenging ones like protein-protein interactions and intrinsically disordered proteins
Cell Culture Methods for in vitro Toxicology introduces the reader to a range of techniques involved in the use of in vitro cell culture in toxicological studies. It deals with major cell types studied in the field of toxicology and will be useful for anyone wishing to start work with animal cell cultures or to refresh their knowledge relating to in vitro cell models. Fundamental chapters deal with the general biology of cytotoxicity and cell immortalisation these are key issues for in vitro systems addressing the `3Rs' principle. Up-to-date overviews deal with the use of cells from liver, brain and intestine. In addition, biochemical analysis of cell responses, biotransformation pathways in cells and recombinant approaches to the early detection of cell stress are also covered in detail. Prominent features of in vitro technologies also include regulation, biosafety and standardisation. Dedicated chapters deal with these issues in a practical way in order to lead the reader to the right source of information. This book provides an up-to-date, informative and practical review of cell culture methods for in vitro toxicology. It will be of equal benefit to students and experienced toxicologists with little experience of in vitro cell culture.
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.
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.
Microsomes and Drug Oxidations is a record of the proceedings of the Third International Symposium on Microsomes and Drug Oxidations, held in Berlin, Germany in July 1976. The compendium provides an overview of knowledge on the oxidative metabolism of drugs, carcinogens, and various other environmental chemicals. Topics discussed include lipid structure of liver microsomal membranes; interactions between cytochrome p-450 and nadphcytochrome p-450 reductase in the microsomal membrane; impact of drug monoxygenases in clinical pharmacology; and the manner in which oxygen participates in mixed-function oxidation reactions. Pharmacologists, toxicologists, biochemists, and researchers in the pharmaceutical industry will find the book highly insightful.
This work is devoted to the study of the endocrine-related effects on human health with special reference to carcinogenesis, and to the assessment of carcinogenic risk. After providing basic information at the general, cellular and molecular levels, the contents focus on the paradigm of biologically-based risk assessment, as developed form physiologically-based toxicokinetic models. The analysis of this material is proposed as the novel parameters for developing biologically-based models of carcinogenesis, considered to be more relevant to risk assessment than traditional approaches.
