Combinatorial Organic Chemistry

The new time-saving revolution in drug discovery. Combinatorial chemistry, a method for synthesizing millions of chemical compounds much faster than usual, is becoming one of the most useful technical tools available to chemists and researchers working today. Using current advances in computer and laboratory techniques, combinatorial chemistry has freed professionals from the drudgery of piecemeal experimental work and opened new creative possibilities for experimentation. Combinatorial Chemistry: Synthesis and Application details critical aspects of the technique, featuring the work of some of the world's leading chemists, many of whom played a key role in its development. Including examples of both solution-phase and solid-phase approaches as well as the full complement of organic chemistry technologies currently available, the book describes: * Concepts and terms of combinatorial chemistry * Polymer-supported synthesis of organic compounds * Macro beads as microreactors * Solid-phase methods in combinatorial chemistry * Encoded combinatorial libraries, including Rf-encoding of synthesis beads * Strategies for combinatorial libraries of oligosaccharides * Combinatorial libraries of peptides, proteins, and antibodies using biological systems. While combinatorial chemistry originated in peptide chemistry, this volume has deliberately focused on nonpeptide organic applications, illustrating the technique's wide uses. Combinatorial Chemistry introduces organic, medicinal, and pharmaceutical chemists as well as biochemists to this exciting, cost-effective, and practical technique, which has unlocked creative potential for the next millennium.

Combinatorial chemistry, by accelerating the process of chemical synthesis, is having a profound effect on all branches of chemistry, but especially on drug discovery. This informative text explains the origins of combinatorial chemistry and puts the many diverse library methods into context.It explains why some techniques are generally applicable and others are for specialists only. It also focuses on the renaissance of solid phase chemistry and describes the range of available reactions. This is the first single author book in this important, growing field and it describes thebeneficial impact of combinatorial chemistry, especially for the discovery and optimisation of biologically active molecules. This concise and comprehensive overview of combinatorial techniques is an essential text for final year undergraduates, postgraduates, academics and industrialists inchemistry, bio-orgainc chemistry, medicinal chemistry and drug discovery. It provides an accessible introduction to the area for those new to these methods and a valuable reference text to those experienced in this field.

Combinatorial Chemistry is a genuine practical guide covering all the major areas of combinatorial chemistry from an experimental and conceptual point of view. Being one of the most powerful of modern technologies, combinatorial chemistry has had implications to many areas of chemistry and biology and the current approaches to drug, catalyst, receptor, and materials development and discovery are all included in this volume. It also contains protocols on solid, liquid, and solution phase synthesis and expedient methods of library screening and evaluation. The use of automation and robotics is also explained. It is written at a level easily accessible to novices and will enable readers to use combinatorial techniques to the best advantage.

This is a book which considers several isomer-enumeration methods in organic chemistry. Three main topics are exemplified here: viz., theorem of polya, coset representation theory and marks of a group (method of Fujita) and wreath and generalized wreath product groups (method of Balasubramanian). Rigorous proofs have been replaced by an example-oriented, intuitive approach which exposes many problems of real chemical importance.

The story of success goes on and on - with a new book on combinatorial chemistry, edited by Gunther Jung! Combinatorial chemistry is a proven time- and resource-saving synthetic method of outstanding importance for industrial processes. Compound libraries help to save time and money, especially in the search for new drugs, and therefore play a pivotal role in solving the problem of the worldwide increasing demand for new and more active drugs. Not only substances, which are of interest for pharmaceutical chemistry, but also materials, catalysts, and biomolecules such as DNA or oligosaccharides are readily available with high structural diversities. The broad scope of combinatorial sciences is reflected by this book, edited by Gunther Jung: The synthetic methods discussed range from solid-phase to solution-phase synthesis, from preparations of small molecules such as amines or alcohols to those of complex biomolecules. Feasible methods, efficient techniques, new trends in automation, and state-of-the-art fast instrumental analytical and screening methods are presented with many practical tips and tricks for everybody working in combinatorial chemistry. This is the book written by specialists for specialists and for everyone aspiring to become an insider! It is an indispensible source of information for researchers working in organic synthesis, catalysis, biochemistry, and biotechnology, pharmaceutical and clinical chemistry, material sciences, and analytical chemistry.

The words "Combinatorial Chemistry" have different meanings to different people, ranging from split and mix strategies to parallel synthesis using robots, and embracing the whole range of preparative chemistry from organic molecules, to catalyst ligands, and even inorganic solids. All of these activities have in common an attempt to expand the diversity of structure available to the chemist as well as the access to this diversity, permitting the discovery of new and valuable biological acid material properties. In this outstanding survey of combinatorial organic chemistry, the authors, Obrecht who has established a new combinatorial chemistry company called Polyphor, and Villalgardo have brought together the literature, including that from 1998, and have concisely analysed the applications and achievements of this new field. This work will be of value to all chemists engaged in preparative work, both in industry and academe.

Several books on the market cover combinatorial techniques, but they offer just a limited perspective of the field, focusing on selected aspects without examining all approaches and integrated technologies. Combinatorial Chemistry and Technologies: Methods and Applications answers the demand for a complete overview of the field, covering all of the methodologies used in the design, synthesis, and screening of molecular libraries. Now in its second edition, this volume updates prior content and explores new areas such as catalysis, applications in biotechnology, and current ICS-UNIDO activities. Topics include the generation of molecular diversity by chemical methods using solution- and solid-phase chemistries, biological approaches for the production and screening of peptides, antibody and oligonucleotide libraries, and the application of computer-assisted approaches to guide library synthesis. The book establishes the link between combinatorial chemistry and molecular modeling and illustrates the importance of economics and patenting in combinatorial technologies. Valuable to technologists and researchers as an introductory survey on the many aspects of combinatorial chemistry and combinatorial technology, Combinatorial Chemistry and Technologies: Methods and Applications offers an overview of a field that promises broad applicability in the identification of new drugs, as well as in diagnostics, new materials, and catalysis.

"Provides comprehensive coverage of the current combinatorial methodologies and technologies employed for the design, synthesis, and screening of molecular ""libraries."" Features assessments of computer-assisted approaches to guiding library synthesis.
