Summary : The purpose of Ligand Efficiency Indices for Drug Discovery: Towards an Atlas-Guided Paradigm is to introduce in a concise and self-contained form the concepts, ideas, applications and examples of efficiency-driven drug discovery to the biomedical community at large. The book emphasizes the use of 'new variables' and more objective numerical methods to drive drug discovery in an encompassing way. These 'new variables' are based on Ligand Efficiency Indices (LEIs) formulated in a way that permits mapping Chemico-Biological Space (CBS) in an Atlas-like representation. It provides a practical and timely discussion of the concepts, ideas, applications and examples of efficiency-driven drug discovery. This book emphasizes the use of a graphical representation and objective numerical methods to drive drug discovery more effectively. It presents the definition of LEIs and the corresponding efficiency planes within an atlas-like environment to provide a robust graphical and numerical framework for medicinal chemists and drug-discoverers. Provides a practical and timely discussion of the concepts, ideas, applications and examples of efficiency-driven drug discovery Emphasizes the use of ‘new variables’ and more objective numerical methods to drive quicker and more effective drug discovery Presents the definition of Ligand Efficiency Indices (LEIs) and the corresponding efficiency planes as key concepts to provide a graphical and numerical framework

Summary : 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.

Summary : Several drug discovery approaches has been performed to find new compounds able to interact with high affinity with the hormone binding site of the homotetrameric protein transthyretin (TTR), and stabilize this tetramer, becoming drug candidates to treat several rare amyloid diseases associated with TTR. With this aim, several computational workflows and chemico-biological databases have been developed, and in collaboration with two experimental research laboratories of our TTR Consortium (one contributing with the chemical synthesis or acquisition of the designed compounds, and the other contributing with the biological activity assay results for the synthesized or acquired compounds). The specific objectives of this thesis are: a) The generation of a chemico-biological database containing the historical and newly generated results of the TTR Consortium, containing the chemical structures and biological activities of the TTR ligands. b) Explore the possibility of using repurposing techniques applied to the discovery of new TTR inhibitors among the existing drugs, with particular focus on anti-inflammatory drugs, which are known to be good TTR ligands. c) Design of new flavonoid compounds as TTR ligands by means of structure-based drug design. d) Incorporate the Ligand Efficiency Indices analysis (both retrospective and prospective) as a new tool for designing new compounds with increased efficiency as TTR ligands. e) The computational development of a combined predictive/experimental workflow for the analysis of the metabolic stability of TTR ligands, as a tool for improving the prioritized compounds in our in-house database to obtain new compounds with better metabolic and pharmacokinetic properties. Among this thesis those workflows have been developed in order to obtain possible new amyloidogenic inhibitors: a) A computational workflow to obtain TTR ligand fingerprints has been developed, and the application of this workflow to the repurposing of marketed antiinflammatory drugs has delivered 3 compounds as new TTR stabilizers. b) A computational workflow to obtain a TTR-protein structure based pharmacophore has been developed, and the application of this workflow to a database of flavonoid compounds has delivered one compound as a new TTR stabilizer.

Summary : In this comprehensive two-volume resource on the topic senior lead generation medicinal chemists present a coherent view of the current methods and strategies in industrial and academic lead generation. This is the first book to combine both standard and innovative approaches in comparable breadth and depth, including several recent successful lead generation case studies published here for the first time. Beginning with a general discussion of the underlying principles and strategies, individual lead generation approaches are described in detail, highlighting their strengths and weaknesses, along with all relevant bordering disciplines like e.g. target identification and validation, predictive methods, molecular recognition or lead quality matrices. Novel lead generation approaches for challenging targets like DNA-encoded library screening or chemical biology approaches are treated here side by side with established methods as high throughput and affinity screening, knowledge- or fragment-based lead generation, and collaborative approaches. Within the entire book, a very strong focus is given to highlight the application of the presented methods, so that the reader will be able to learn from `real life? examples. The final part of the book presents several lead generation case studies taken from different therapeutic fields, including diabetes, cardiovascular and respiratory diseases, neuroscience, infection and tropical diseases. The result is a prime knowledge resource for medicinal chemists and for every scientist involved in lead generation.

Summary : 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.
