In the next couple of years the human genome will be fully sequenced. This will provide us with the sequence and overall function of all human genes as well as the complete genome for many micro-organisms. Subsequently it is hoped, by means of powerful bioinformatic tools, to determine the gene variants that contribute to various multifactorial diseases and genes that exist in certain infectious agents but not humans. As a consequence, this will allow us to define the most appropriate levels for drug intervention. It can be expected that the number of potential drug targets will increase, possibly by a factor of 10 or more. Nevertheless, sequencing the human genome or, for that matter, the genome of other species will only be the starting point for the understanding of their biological function. Structural genomics is a likely follow-up, combined with new techniques to validate the therapeutic relevance of such newly discovered targets. Accordingly, it can be expected that in the near future we will witness a substantial increase in novel putative targets for drugs. To address these new targets effectively, we require new approaches and innovative tools. At present, two alternative, yet complementary, techniques are employed: experimental high-throughput screening (HTS) of large compound libraries, increasingly provided by combinatorial chemistry, and computational methods for virtual screening and de novo design. As kind of status report on the maturity of virtual screening as a technique in drug design, the first workshop on new approaches in drug design and discovery was held in March 1999, at Schloß Rauischholzhausen, near Marburg in Germany. More than 80 scientists gathered and discussed their experience with the different techniques. The speakers were invited to summarize their contributions together with their impressions on the present applicability of their approach. Several of the speakers followed this request which is summarized in this publication.

The explosion in the generation of information parallels the explosion of computational resources. The use of computers to collect, store and manipulate chemical information is at the heart of chemoinformatics. These methodologies, whose main target thus far has been the pharmaceutical field, are general and can be applied to other types of chemical data sets, such as those containing food chemicals. While the use of chemical information methodologies to address food-related challenges is still in its infancy, interest is growing and will continue to do so as the methods prove useful, particularly for providing practical solutions to food industry challenges. Foodinformatics gives an overview of basic concepts, applications, tools and perspectives of the emerging field of foodinformatics. The book is an important addition to the literature and will be of interest of food chemists, nutritionists, informaticians and scientists of related fields.

Protein Homeostasis Diseases: Mechanisms and Novel Therapies offers an interdisciplinary examination of the fundamental aspects, biochemistry and molecular biology of protein homeostasis disease, including the use of natural and pharmacological small molecules to treat common and rare protein homeostasis disorders. Contributions from international experts discuss the biochemical and genetic components of protein homeostasis disorders, the mechanisms by which genetic variants may cause loss-of-function and gain-of-toxic-function, and how natural ligands can restore protein function and homeostasis in genetic diseases. Applied chapters provide guidance on employing high throughput sequencing and screening methodologies to develop pharmacological chaperones and repurpose approved drugs to treat protein homeostasis disorders. - Provides an interdisciplinary examination of protein homeostasis disorders, with an emphasis on treatment strategies employing small natural and pharmacological ligands - Offers applied approaches in employing high throughput sequencing and screening to develop pharmacological chaperones to treat protein homeostasis disease - Gathers expertise from a range of international chapter authors who work across various biological methods and disease specific disciplines of relevance

The last decade has seen the confluence of several enabling technologies that have allowed protein crystallographic methods to live up to their true potential. Taken together, the numerous recent advances have made it possible to tackle difficult biological targets with a high probability of success: intact bacterial ribosomes have been structurally elucidated, as well as eukaryotic trans-membrane proteins like the potassium channel and GPCRs. It is now possible for medicinal chemists to have access to structural information on their latest small molecule candidates bound to the therapeutic target within days of compound synthesis, allowing structure guided ligand optimization to occur in "real time". Structure-Based Drug Discovery presents an array of methods used to generate crystal structures of biological macromolecules, how to leverage the structural information to design novel ligands anew, and how to iteratively optimize hits and convert them to leads. Written in the successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Structure-Based Drug Discovery aims to provide scientists interested in adding SBDD to their arsenal of drug discovery methods with well-honed, up-to-date methodologies.

The Practice of Medicinal Chemistry, 2E, is a single-volume source on the practical aspects of medicinal chemistry. The successful first edition was nicknamed "The Bible" by medicinal chemists, and the second edition has been updated, expanded and refocused to reflect developments over the last decade. Emphasis is put on how medicinal chemists conduct their search for and design of new drug entities. In contrast to competing books, it focuses on the chemistry rather than pharmacological concepts or descriptions of the various therapeutic classes of drugs. Most medicinal chemists working in the pharmaceutical industry are organic synthetic chemists who must acquire a strong knowledge of medicinal chemistry as they enter the industry. This book aims to be their practical handbook - a complete guide to the drug discovery process. - The only book available dealing with the practical aspects of medicinal chemistry - Serves as a complete guide to the drug discovery process, from conception of the molecules to drug production - Updated chapters devoted to the discovery of new lead compounds, including combinatorial chemistry

In the post-genomic era, one of the key challenges for drug discovery is making optimal use of the comprehensive genomic data available after the elucidation of the human genome and others in order to identify effective new medicines. Addressing this challenge, chemogenomics aims to identify systematically all ligands and modulators for all the gene products expressed and allows the accelerated exploration of their biological function. The subject brings together diverse disciplines including chemistry, genetics, chemo- and bioinformatics, structural biology, and biological screening in phenotypic and target-based assays.This book uniquely integrates reviews of the latest cutting-edge research by leaders in the various disciplines, providing a general, knowledge-centric overview of the different chemical, biological and informatics components. Unlike existing publications, the book focuses on how these disciplines interact efficiently for the rapid discovery of new targets and their effector molecules simultaneously. Examples of chemogenomics approaches pursued in academia as well as in biotech and pharmaceutical companies are also provided.
