E-Book Overview
Mass Spectrometry in Drug Discovery summarizes the theory, instrumentation, techniques, and application of mass spectrometry and atmospheric pressure ionization to screening, evaluating, and improving the performance and quality of drug candidates. It provides time- and cost-efficient approaches for the generation and analysis of effective pharmaceuticals, covers advances in combinatorial chemistry, molecular biology, bioanalysis automation, and computing, and demonstrates the use of mass spectrometry in the assessment of disease states, drug targets, and potential drug agents.

With the possible exception of combinatorial chemistry, no single technology has revolutionized and streamlined the drug discovery process to such a great extent. In the hopes of expediting the drug discovery process, major pharmaceutical companies have invested considerable financial and human resources in mass spectrometers. Current pharmaceutical development has become more demanding, especially with the advent of high-throughput discovery programs across the industry in the areas of chemistry, pharmacology, and pharmacokinetics. In this regard, interdisciplinary rapid-screening protocols that allow for the examination of an increased number of new chemical entities (NCEs) have arisen. Many of these new screening protocols have been successful due in large part to the ability of the mass spectrometer to function as a sensitive and selective detector with minimal method development effort. Drug discovery has been the subject of many articles in peer-reviewed journals, but until now no concise treatise had been written to bring together the numerous applications of mass spectrometry and drug discovery. Mass Spectrometry in Drug Discovery is intended to bring the knowledge gap that the widespread use of LC/MS has created. From a practical and applied point of view, the text will introduce readers to the basic concepts of mass spectrometry and atmospheric pressure ionization LC/MS. Although many aspects of mass spectrometry are encompassed, the book focuses more on applications associated with pharmaceutics, pharmacokinetics, and combinatorial chemistry; iii iv Preface it is not intended to incorporate the abundance of applications in the areas of pharmacology and toxicology. Nor is this book intended just for those in drug metabolism who have extensive experience in mass spectrometry. Rather, it is hoped that any scientist interested in applying LC/MS to drug discovery will benefit, including those who may not have received any prior training in the area. Moreover, this book should serve as a background text for those wh
