Kinetics of Enzyme Action


Book Description

Few scientists have the knowledge to perform the studies that are necessary to discover and characterize enzyme inhibitors, despite the vested interest the pharmaceutical industry has in this field. Beginning with the most basic principles pertaining to simple, one-substrate enzyme reactions and their inhibitors, and progressing to a thorough treatment of two-substrate enzymes, Kinetics of Enzyme Action: Essential Principles for Drug Hunters provides biochemists, medicinal chemists, and pharmaceutical scientists with numerous case study examples to outline the tools and techniques necessary to perform, understand, and interpret detailed kinetic studies for drug discovery.




Evaluation of Enzyme Inhibitors in Drug Discovery


Book Description

Vital information for discovering and optimizing new drugs "Understanding the data and the experimental details that support it has always been at the heart of good science and the assumption challenging process that leads from good science to drug discovery. This book helps medicinal chemists and pharmacologists to do exactly that in the realm of enzyme inhibitors." -Paul S. Anderson, PhD This publication provides readers with a thorough understanding of enzyme-inhibitor evaluation to assist them in their efforts to discover and optimize novel drug therapies. Key topics such as competitive, noncompetitive, and uncompetitive inhibition, slow binding, tight binding, and the use of Hill coefficients to study reaction stoichiometry are all presented. Examples of key concepts are presented with an emphasis on clinical relevance and practical applications. Targeted to medicinal chemists and pharmacologists, Evaluation of Enzyme Inhibitors in Drug Discovery focuses on the questions that they need to address: * What opportunities for inhibitor interactions with enzyme targets arise from consideration of the catalytic reaction mechanism? * How are inhibitors evaluated for potency, selectivity, and mode of action? * What are the advantages and disadvantages of specific inhibition modalities with respect to efficacy in vivo? * What information do medicinal chemists and pharmacologists need from their biochemistry and enzymology colleagues to effectively pursue lead optimization? Beginning with a discussion of the advantages of enzymes as targets for drug discovery, the publication then explores the reaction mechanisms of enzyme catalysis and the types of interactions that can occur between enzymes and inhibitory molecules that lend themselves to therapeutic use. Next are discussions of mechanistic issues that must be considered when designing enzyme assays for compound library screening and for lead optimization efforts. Finally, the publication delves into special forms of inhibition that are commonly encountered in drug discovery efforts, but can be easily overlooked or misinterpreted. This publication is designed to provide students with a solid foundation in enzymology and its role in drug discovery. Medicinal chemists and pharmacologists can refer to individual chapters as specific issues arise during the course of their ongoing drug discovery efforts.

Metabolism of Drugs and Other Xenobiotics


Book Description

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.




Molecular Mechanisms Of Drug Action


Book Description

In this book the targets of drug action are the central focus - whether they be enzymes in a pathway or membrane-bound receptors and ion channels. This approach distinguishes the book from others in the f ield which consider the subject mainly in terms of disease.; The introductory chapter is concerned with the basic principles that cover enzyme inhibition and receptor binding by drugs. The next seven chapters deal with drugs that modulate biochemical pathways, both of synthesis and breakdown, while the last four chapters are concerned with organizational structures of the cell.; The book brings together the state of knowledge with respect to drug action and emphasizes mechanistic aspects of drug action. It encompasses the modes of action of drugs for infectious disease and those for endogenous conditions. There is a listing of reviews and essay questions are provided for each chapter.
