Hydrolysis in Drug and Prodrug Metabolism


Book Description

Many drugs and other xenobiotics (e.g., preservatives, insecticides, and plastifiers) contain hydrolyzable moieties such as ester or amide groups. In biological media, such foreign compounds are, therefore, important substrates for hydrolytic reactions catalyzed by hydrolases or proceeding non-enzymatically. Despite their significance, until now, no book has been dedicated to hydrolysis and hydrolases in the metabolism of drugs and other xenobiotics. This work fills a gap in the literature and reviews metabolic reactions of hydrolysis and hydarion from the point of views of enzymes, substrates, and reactions.




The Biochemistry of Foreign Compounds


Book Description

The Biochemistry of Foreign Compounds presents the various aspects of biochemistry of foreign compounds in relation to toxicology, pathology, and pharmacology. This book discusses the classification of foreign compounds according to usage, namely, food additives, drugs, pesticides, industrial chemicals, and natural foreign compounds. Organized into two sections encompassing 12 chapters, this book starts with the absorption and secretion of foreign compounds. This text then discusses the two phases of reaction in the metabolism of foreign compounds. Other chapters consider the rate at which each reaction proceeds wherein its relative significance may be affected by many factors that may result in changes in the pattern of metabolism and differences in toxicity. This book discusses as well the physiological factors that affect metabolism, including age, sex, pregnancy, disease, and the nutritional state of the animal. The final chapter deals with the metabolism of some of the commonly used industrial chemicals. This book is a valuable resource for biochemists, chemists, toxicologists, pharmacologists, and pathologists.




Medical Biochemistry


Book Description

This second edition of Medical Biochemistry is supported by more than 45 years of teaching experience, providing coverage of basic biochemical topics, including the structural, physical, and chemical properties of water, carbohydrates, lipids, proteins, and nucleic acids. In addition, the general aspects of thermodynamics, enzymes, bioenergetics, and metabolism are presented in straightforward and easy-to-comprehend language. This book ties these concepts into more complex aspects of biochemistry using a systems approach, dedicating chapters to the integral study of biological phenomena, including cell membrane structure and function, gene expression and regulation, protein synthesis and post-translational modifications, metabolism in specific organs and tissues, autophagy, cell receptors, signal transduction pathways, biochemical bases of endocrinology, immunity, vitamins and minerals, and hemostasis. The field of biochemistry is continuing to grow at a fast pace. This edition has been revised and expanded with all-new sections on the cell plasma membrane, the human microbiome, autophagy, noncoding, small and long RNAs, epigenetics, genetic diseases, virology and vaccines, cell signaling, and different modes of programmed cell death. The book has also been updated with full-color figures, new tables, chapter summaries, and further medical examples to improve learning and better illustrate the concepts described and their clinical significance. - Integrates basic biochemistry principles with molecular biology and molecular physiology - Illustrates basic biochemical concepts through medical and physiological examples - Utilizes a systems approach to understanding biological phenomena - Fully updated for recent studies and expanded to include clinically relevant examples and succinct chapter summaries







Principles of Biochemical Toxicology, Third Edition


Book Description

Research into the biochemical basis of toxicology has expanded rapidly over recent years, amidst concerns over the adverse effects of drugs, environmental pollution and occupational hazards. Following on from the acclaimed first two editions of Principles of Biochemical Toxicology, John Timbrell has expanded the text to include: summary sections questions and model answers thoroughly revised artwork These features, plus the new easy-to-read format will make biochemical toxicology more accessible to undergraduates and postgraduates coming across the subject for the first time, particularly when undertaking self-directed study. This comprehensive textbook provides a thorough explanation of dose-response relationships; disposition and metabolism; toxic responses to foreign compounds, and detailed examples to illustrate mechanisms of toxicity. There is also an expanded and updated bibliography, directing the reader to further reading if required. Students and lecturers will find the clear and concise approach, which established this book as the leading textbook in its field, an essential aid to learning and teaching.




Concepts in Biochemical Pharmacology


Book Description

This volume of the Handbook of Experimental Pharmacology (Concepts in Biochemical Pharmacology) will show that pharma cology has finally arrived as a true discipline in its own right, and is no longer the handmaiden of organic chemistry and physiology. Instead it is an amalgam of all the biological sciences including biochemistry, biophysical chemistry, physiology, pathology and clinical medicine. In the volumes that make up Concepts in Bio chemical Pharmacology we hope to convince Medical Schools what should now be obvious, that pharmacology is no longer that dull topic bridging the basic sciences with medicine, but is probably the most important subject in the medical curriculum. We are grateful for the advice of Dr. Byron Clark, Director of the Pharmacology-Toxicology Program at the National Institutes of Health whose support made possible much of the work described in this volume.
