In recent years the fundamental concepts and applied methodologies of molecular similarity analysis have experienced a revolutionary development. Motivated by the increased degree of understanding of elementary molecular properties on the levels ranging from fundamental quantum chemistry to the complex interactions of biomolecules, and aided by the spectacular progress in computer technology and access to computer power, the area has opened up to many new ideas and new approaches. This book covers topics in quantum similarity approaches, electron density shape analysis methods, and it provides better theoretical understanding of molecular similarity. Additionally, quantitative shape analysis, especially activity relations (QShAR) and the prediction of the pharmacological or toxicological effects of molecules in the related context of quantum QSAR (QQSAR). This volume written by the experts in the various subfields of molecular similarity, provides a collection of the most recent ideas, advances, and methodologies. It is the hope of the Editors that by representing these topics within a single volume, the readers will find a balanced overview of the status of the field. We also hope that the book will serve as a tool for selecting and assessing the best approach for various new types of problems of molecular similarity that may arise and it will provide a set of easy references for further studies and applications.

Molecular similarity is the foundational principle for drug design, wherein new molecules are designed that are “similar enough” to known compounds to have a good chance at being active but “different enough” to have a chance at being superior. Quantifying the level of similarity or dissimilarity between two molecules has been a long-standing area of investigation, and decades of research have yielded an impressive array of tools and techniques for measuring and calculating these relationships. Molecular Similarity: Concepts and Applications for Pharmaceutical Research provides a comprehensive review of “best practices” within the field of molecular similarity as it applies to drug design, covering fundamentals and concepts, case studies, and strategies for integration. Topics covered include: • theory and concepts in molecular similarity • 1-D, 2-D and 3-D methods for chemical similarity • biochemical similarity • target similarity – pockets and docking • integrating multiple approaches to chemical similarity • case studies in lead discovery, optimization and target discovery; kinome/GPCR profiling; polypharmacology; and off-target discovery Molecular Similarity: Concepts and Applications for Pharmaceutical Research will appeal to both the newcomer and the expert, providing a foundational text upon which to gain familiarity with the field, develop localized strategies, and conduct further research.

Similarities in chemical reactivity depend on molecular properties, and are ultimately dependent on the similarities of electronic structures. Fundamentally, quantum chemical similarities are manifested in similarities of molecular behaviour. This book covers both the quantum chemical origins and the methods of phenomenological descriptions of molecular similarity. The emphasis on reactivity is a unique feature. The exposition of computational methods and the prediction of reactivities, as well as the description of actual computer programs constitute important aspects of the book. Specific applications in drug design and techniques for the interpretation of the roles of functional groups in reactivity are of interest in molecular engineering. The selection of topics provides a detailed and balanced introduction to the field of similarity-based assessment of chemical reactivity. For researchers and graduate students in both fundamental chemistry and applied fields, such as biochemistry, pharmacology and drug design.

Over the past years, the chem(o)informatics field has further evolved and new application areas have opened up, for example, in the broadly defined area of chemical biology. In Chemoinformatics and Computational Chemical Biology, leading investigators bring together a detailed series of reviews and methods including, among others, system-directed approaches using small molecules, the design of target-focused compound libraries, the study of molecular selectivity, and the systematic analysis of target-ligand interactions. Furthermore, the book delves into similarity methods, machine learning, probabilistic approaches, fragment-based methods, as well as topics that go beyond the current chemoinformatics spectrum, such as knowledge-based modeling of G protein-coupled receptor structures and computational design of siRNA libraries. As a volume in the highly successful Methods in Molecular BiologyTM series, this collection provides detailed descriptions and implementation advice that are exceedingly relevant for basic researchers and practitioners in this highly interdisciplinary research and development area. Cutting-edge and unambiguous, Chemoinformatics and Computational Chemical Biology serves as an ideal guide for experts and newcomers alike to this vital and dynamic field of study.
