Conceptual and technological advances in chemistry and biology have transformed the drug discovery process. Evolutionary pressure among the diverse scientific and engineering disciplines that contribute to the identification of biologically active compounds has resulted in synergistic improvements at every step in the process. Exploiting Chemical Diversity for Drug Discovery encompasses the many components of this transformation and presents the current state-of-the-art of this critical endeavour. From the theoretical and operational considerations in generating a collection of compounds to screen, to the design and implementation of high-capacity and high-quality assays, this book provides a comprehensive overview of modern approaches to lead identification.
