Affinity And Efficacy The Components Of Drug Receptor Interactions

The interaction of a drug with a receptor generates a code of information having components of affinity and efficacy. How this information is translated into a response depends on the unique cells, tissue, organ or system in which the receptor resides. This book describes how to analyze various responses to estimate the affinity and efficacy components of the initial drug-receptor interaction. More specifically, it describes how to measure the affinity and efficacy of drugs through the analysis of single receptor activity, the activation state of a population of receptors, and responses downstream from receptor activation. More light is thrown on ligand-gated ion channels and G protein-coupled receptors in this book.The topics discussed include radioligand binding, estimation of agonist affinity and efficacy, competitive antagonism, inverse agonism, allosteric agonists and modulators, agonist bias, modulation of pathway selectivity, and the estimation of ligand affinity for active and inactive receptor states. The natural history and structure of ligand-gated ion channels, G proteins, and G protein-coupled receptors are also discussed.

The interaction of a drug with a receptor encodes a vector of information having components of affinity and efficacy. How this information is translated into a response depends on the unique cells, tissue, organ or system in which the receptor resides.

More specifically, it describes how to measure the affinity and efficacy of drugs through the analysis of single receptor activity, the activation state of a population of receptors, and responses downstream from receptor activation. More light is shed on ligand-gated ion channels and G protein-coupled receptors in this book. The topics discussed include radioligand binding, estimation of agonist affinity and efficacy, competitive antagonism, inverse agonism, allosteric agonists and modulators, ligand-directed signaling, modulation of pathway selectivity, and the analysis of the loss of function in tissues from receptor knockout mice. The natural history and structure of ligand-gated ion channels, G proteins, and G protein-coupled receptors are also discussed.

A quick reference to basic science for anaesthetists, containing all the key information needed for FRCA exams.

A guide to quantitative drug-receptor pharmacology, this new edition aims to cover all receptor systems, whether derived from molecular biology or animal studies. Using existing data, it demonstrates how theoretical models facilitate drug development, and integrates theory with practice. This second edition aims to be a valuable resource for all researchers involved in the drug design and development process. Not only has the text been updated and revised, but reflecting the significant technical breakthroughs of recent years, it now more generally encompasses all receptor systems, whether derived from molecular biology or whole animal studies. These systems are examined within the framework of current drug receptor theories, particularly the receptor occupation theory, the operational model of drug action and the ternary complex model.

The second edition of Fundamentals of Anaesthesia builds upon the success of the first edition, and encapsulates the modern practice of anaesthesia in a single volume. Written and edited by a team of expert contributors, it provides a comprehensive but easily readable account of all of the information required by the FRCA Primary examination candidate and has been expanded to include more detail on all topics and to include new topics now covered in the examination. As with the previous edition, presentation of information is clear and concise, with the use of lists, tables, summary boxes and line illustrations where necessary to highlight important information and aid the understanding of complex topics. Great care has been taken to ensure an unrivalled consistency of style and presentation throughout.

For the past four decades, University College London has offered a renowned course on receptor pharmacology. Originating from this course, the perennially bestselling Textbook of Receptor Pharmacology has presented in-depth coverage of this rapidly expanding area of research. This third edition continues to combine current understanding of classica

Numerous phenomenal advances have been made towards understanding the role of neurotransmitters in the pathophysiology of neurological disorders, and these have resulted in a large number of novel molecules with the potential to revolutionize the treatment and prevention of such disorders. This book provides a comprehensive and detailed explanation of brain neurotransmitters and their receptors and associated channels. It includes a basic introduction, and also discusses the functions and recent advances and their pharmacology, highlighting the role of various computer aided drug design (CADD) strategies for the development of therapeutic ligands to modulate these receptors/ion channels. Written in an easy-to-read style, it is intended for neuroscience and pharmaceutical students and researchers working in the area of brain neurotransmitters.

In recent years our understanding of molecular mechanisms of drug action and interindividual variability in drug response has grown enormously. Meanwhile, the practice of anesthesiology has expanded to the preoperative environment and numerous locations outside the OR. Anesthetic Pharmacology: Basic Principles and Clinical Practice, 2nd edition, is an outstanding therapeutic resource in anesthesia and critical care: Section 1 introduces the principles of drug action, Section 2 presents the molecular, cellular and integrated physiology of the target organ/functional system and Section 3 reviews the pharmacology and toxicology of anesthetic drugs. The new Section 4, Therapeutics of Clinical Practice, provides integrated and comparative pharmacology and the practical application of drugs in daily clinical practice. Edited by three highly acclaimed academic anesthetic pharmacologists, with contributions from an international team of experts, and illustrated in full colour, this is a sophisticated, user-friendly resource for all practitioners providing care in the perioperative period.
