Fragment-based drug discovery (FBDD) is a new paradigm in drug discovery that utilizes very small molecules - fragments of larger molecules. It is a faster, cheaper, smarter way to do drug discovery, as shown by the number of pharmaceutical companies that have embraced this approach and the biotechnology companies who use fragments as their sole source of drug discovery. Fragment-Based Drug Discovery: A Practical Approach is a guide to the techniques and practice of using fragments in drug screening. The emphasis is on practical guidance, with procedures, case studies, practical tips, and contributions from industry. Topics covered include: an introduction to fragment based drug discovery, why using fragments is a more efficient process than predominant models, and what it means to have a successful FBDD effort. setting up an FBDD project library building and production NMR in fragment screening and follow up application of protein-ligand NOE matching to the rapid evaluation of fragment binding poses target immobilized NMR screening: validation and extension to membrane proteins in situ fragment-based medicinal chemistry: screening by mass spectrometry computational approaches to fragment and substructure discovery and evaluation virtual fragment scanning: current trends, applications and web based tools fragment-based lead discovery using covalent capture methods case study from industry: the identification of high affinity beta-secretase inhibitors using fragment-based lead generation With contributions from industry experts who have successfully set up an industrial fragment-based research program, Fragment-Based Drug Discovery: A Practical Approach offers essential advice to anyone embarking on drug discovery using fragments and those looking for a new approach to screening for drugs.

There are numerous excellent reviews on fragment-based drug discovery (FBDD), but there are to date no hand-holding guides or protocols with which one can embark on this orthogonal approach to complement traditional high throughput screening methodologies. This Methods in Enzymology volume offers the tools, practical approaches, and hit-to-lead examples on how to conduct FBDD screens. The chapters in this volume cover methods that have proven to be successful in generating leads from fragments, including chapters on how to apply computational techniques, nuclear magnetic resonance, surface plasma resonance, thermal shift and binding assays, protein crystallography, and medicinal chemistry in FBDD. Also elaborated by experienced researchers in FBDD are sample preparations of fragments, proteins, and GPCR as well as examples of how to generate leads from hits.

From its origins as a niche technique more than 15 years ago, fragment-based approaches have become a major tool for drug and ligand discovery, often yielding results where other methods have failed. Written by the pioneers in the field, this book provides a comprehensive overview of current methods and applications of fragment-based discovery, as well as an outlook on where the field is headed. The first part discusses basic considerations of when to use fragment-based methods, how to select targets, and how to build libraries in the chemical fragment space. The second part describes established, novel and emerging methods for fragment screening, including empirical as well as computational approaches. Special cases of fragment-based screening, e. g. for complex target systems and for covalent inhibitors are also discussed. The third part presents several case studies from recent and on-going drug discovery projects for a variety of target classes, from kinases and phosphatases to targeting protein-protein interaction and epigenetic targets.

Fragment-based drug discovery is a rapidly evolving area of research, which has recently seen new applications in areas such as epigenetics, GPCRs and the identification of novel allosteric binding pockets. The first fragment-derived drug was recently approved for the treatment of melanoma. It is hoped that this approval is just the beginning of the many drugs yet to be discovered using this fascinating technique. This book is written from a Chemist's perspective and comprehensively assesses the impact of fragment-based drug discovery on a wide variety of areas of medicinal chemistry. It will prove to be an invaluable resource for medicinal chemists working in academia and industry, as well as anyone interested in novel drug discovery techniques.
