A consolidated and comprehensive reference on ligand-binding assays Ligand-binding assays (LBAs) stand as the cornerstone of support for definition of the pharmaco-kinetics and toxicokinetics of macromolecules, an area of burgeoning interest in the pharmaceutical industry. Yet, outside of the Crystal City Conference proceedings, little guidance has been available for LBA validation, particularly for assays used to support macromolecule drug development. Ligand-Binding Assays: Development, Validation, and Implementation in the Drug Development Arena answers that growing need, serving as a reference text discussing critical aspects of the development, validation, and implementation of ligand-binding assays in the drug development field. Ligand-Binding Assays covers essential topics related to ligand-binding assays, from pharmacokinetic studies, the development of LBAs, assay validation, statistical LBA aspects, and regulatory aspects, to software for LBAs and robotics and other emerging methodologies for LBAs. Highlights include: A general discussion of challenges and proven approaches in the development of ligand-binding assays More detailed examination of characteristics of these assays when applied to support of pharmacokinetic and toxicokinetic studies of compounds at different stages in the discovery or development timeline A concise, but detailed, discussion of validation of ligand-binding assays for macromolecules A practical approach to "fit-for-purpose" validation of assays for biomarkers, those molecules receiving increased attention as potentially demonstrating that the target chosen in discovery is being modulated by the candidate therapeutic, both in nonclinical and clinical studies Written by a team of world-recognized authorities in the field, Ligand-Binding Assays provides key information to a broad range of practitioners, both in the pharmaceutical and allied industries and in related contract research organizations and academic laboratories and, perhaps, even in the field of diagnostics and clinical chemistry.

Radiophannaceutical research has recently undergone a major change in direction. In past years it has been concerned mainly with the development of perfusion tracers, the biodistribution of which reflect the regional blood flow to areas of major organs such as the heart and brain. However, a major new direction of interest now lies in the development of receptor-binding radio-tracers which can be used to perform in-vivo characterisation of diseased tissues and it is likely that much of the future research in this field will follow this direction. The difficulties in developing such tracers are considerable. The researcher must first identify a promising target for radiopharmaceutical development. High specific activity radioactive molecules must be designed and synthesised which will both bind to the target receptor with high affinity, and also have the physicochemical characteristics which will allow them to reach the target site in sufficient quantity while at the same time showing minimal uptake in non-target tissues. Thus the knowledge base required for radiophannaceutical development has now expanded beyond the limits of radiopharmaceutical chemistry to include aspects of biochemistry, molecular biology and conventional drug design. The portfolio of basic knowledge required to support current radiopharmaceutical development is changing and scientists working in this arena need to be trained in this regard. At the same time, the very latest developments in the field need to be communicated to the scientific community in order to stimulate the advancement of this exciting new direction of research.

The binding of small ligands to biological molecules is central to most aspects of biological function. The past twenty years has seen the development of an increasing armoury of biophysical methods that not only detect such binding, but also provide varying degrees of information about the kinetics, thermodynamics and structural aspects of the process. These methods have received increasing attention with the growth in more rational approaches to drug discovery and design. This book reviews the latest advances in the application of biophysics to the study of ligand binding. It provides a complete overview of current techniques to identify ligands, characterise their binding sites and understand their binding mechanisms. Particular emphasis is given to the combined use of different techniques and their relative strengths and weaknesses. Consistency in the way each technique is described makes it easy for readers to select the most suitable protocol for their research. The introduction explains why some techniques are more suitable than others and emphasizes the possible synergies between them. The following chapters, all written by a specialist in the particular technique, focus on each method individually. The book finishes by describing how several complimentary techniques can be used together for maximum effectiveness. This book is suitable for biomolecular scientists at graduate or post-doctoral level in academia and industry. Biologists and chemists will also find it a useful introduction to the techniques available.

This is not a book on NO biology, nor about hemoglobin, nor about heme-based sensors per se. Of course, it covers all these topics and more, but above all, it aims at providing a truly multidisciplinary perspective of heme-diatomic interactions. The overarching goal is to build bridges among disciplines, to bring about a meeting of minds. The contributors to this book hail from diverse university departments and disciplines – chemistry, biochemistry, molecular biology, microbiology, zoology, physics, medicine and surgery, bringing with them very different views of heme-diatomic interactions. The hope is that the juxtaposition of this diversity will lead to increased exchanges of ideas, approaches, and techniques across traditional disciplinary boundaries. The authors represent a veritable Who’s Who of heme protein research and include John Olson, Tom Spiro, Walter Zumft, F. Ann Walker, Teizo Kitagawa, W. Robert Scheidt, Pat Farmer, Marie-Alda Gilles-Gonzalez, and many other equally distinguished scientists. Extremely distinguished list of authors Multidisciplinary character – equally suitable for chemists and biochemists Covers the hottest topics in heme protein research: sensors, NO biology, new roles of hemoglobin, etc.

Techniques in the neurosciences are evolving rapidly. There are currently very few volumes dedicated to the methodology - ployed by neuroscrentists, and those that are available often seem either out of date or limited in scope. This series is about the methods most widely used by modern-day neuroscientists and 1s written by their colleagues who are practicing experts. Volume 1 will be useful to all neuroscientists since it concerns those procedures used routinely across the widest range of s- drsciplines. Collecting these general techniques together in a single volume stnkes us not only as a service, but will no doubt prove of exceptional utilitarian value as well. Volumes 2 and 3 describe all current procedures for the analyses of ammes and theirmetabolites and of amino acrds, respectively. These collections will clearly be of value to all neuroscientists working in or contemplating research in these fields. Similar reasons exist for Volume 4 on receptor binding techniques since experimental details are provided for many types of ligand-receptor binding, including chapters on general prin- ples, drug discovery and development, and a most useful app- dix on computer programs for Scatchard, nonlinear, and compe- tive displacement analyses. Volume 5 provides procedures for the assessment of enzymes involved in biogenic amine synthesis and catabolism. Volumes in the NEUROMETHODS series will be useful to neurochemists, -pharmacologists, -physrologists, -anatomists, psychopharmacologists, psychiatrists, neurologists, and chemists (organic, analytical, pharmaceutical, medicinal); in fact, everyone involved in the neurosciences, both basic and clinical.

The interest in opioids such as morphine, the prototypical opioid ligand, has been maintained through the years. The identification of endogenous opioids and their receptors (mu, delta, kappa, and nociceptin), molecular cloning, and the elucidation of the crystal structures of opioid receptors represent key milestones in opioid research. The opioid system modulates numerous pharmacological responses, with therapeutic (i.e., analgesia) and detrimental side effects (i.e., addiction). The medical use and misuse of opioids have dramatically increased, leading to the 21st century opioid crisis. This book presents recent developments in opioid drug discovery, specifically in the medicinal chemistry and pharmacology of new ligands targeting the opioid receptors as effective and safe therapeutics for human diseases. Furthermore, it draws a special attention to advancing concepts and strategies in opioid drug discovery to mitigate opioid liabilities. The diversity among the discussed topics is a testimony to the complexity of the opioid system, which results from the expression, regulation, and functional role of ligands and receptors. The array of multidisciplinary research areas illustrates the rapidly developing basic research and translational activities in opioid drug discovery. This book will serve as a useful reference while also stimulating continued research in the chemistry and pharmacology of opioids and their receptors, with the prospect of developing improved therapies for human diseases, but also improving health and quality of life in general.
