Drug discovery is an expensive, time-consuming process and the modern drug discovery community is constantly challenged not only with discovering novel bioactive agents to combat resistance from known diseases and fight against new ones, but to do so in a way that is economically effective. Advances in both experimental and theoretical/computational methods envisage that the greatest challenges in drug discovery can be most successfully addressed by using a multi-scale approach, drawing on the specialties of a whole host of different disciplines. Multi-Scale Approaches to Drug Discovery furnishes chemists with the detail they need to identify drug leads with the highest potential before isolating and synthesizing them to produce effective drugs with greater swiftness than classical methods may allow. This significantly speeds up the search for more efficient therapeutic agents. After an introduction to multi-scale approaches outlining the need for and benefits of their use, the book goes on to explore a range of useful techniques and research areas, and their potential applications to this process. Profiling drug binding by thermodynamics, machine learning for predicting enzyme sub-classes, and multitasking models for computer-aided design and virtual compound screening are discussed, before the book goes on to review Alkaloid Menispermaceae leads, natural chemotherapeutic agents and methods for speeding up the design and virtual screening of therapeutic peptides. Flavonoids as multi-target compounds are then explored, before the book concludes with a review of Quasi-SMILES as a novel tool. Collecting together reviews and original research contributions written by leading experts in the field, Multi-Scale Approaches to Drug Discovery highlights cutting-edge approaches and practical examples of their implementation for those involved in the drug discovery process at many different levels. Using the combined knowledge of medicinal, computational, pharmaceutical and bio- chemists, it aims to support growth in the multi-scale approach to promote greater success in the development of new drugs.

A book intended for food science researchers, technologists, students, and polymer chemists.;A fundamental understanding of polymers has evolved in recent years concurrent with advances in analytical instrumentation. The theories and methodologies developed for the galacturonan biopolymers (collectively called pectins) have seldom been discoursed comprehensively in the context of the new knowledge. This text explains the scientific and technical basis of many of the practices followed in processing and preparing foods fabricated with or containing pectin. The material is presented in a very readable fashion for those with limited technical training. Topics discussed include structural analysis, commercial extractions methods, pectin formulations and tropical fruit analysis, molecular mechanisms of gelatin, enzymology, and polymer confrontation techniques.
Master's and doctoral students often have unnecessary difficulty with the technical requirements of constructing a research proposal, writing a thesis and submitting it for examination. Students can expect expert supervision in conducting their research and drawing conclusions, but the responsibility for presenting their work in the correct way and in accordance with accepted conventions is theirs alone. This guide has been developed in response to both student's and supervisors' needs. The step-by-step discussion of the entire thesis undertaking spells out information for students that academics often take for granted, and that students often struggle to access on their own.
The first volume of "The Chemistry of the Hydrazo, Azo and Azoxy Groups" was published in 1975 in two parts, and the present book is the second volume of this publication. Since 1975 three supplementary volumes dealing with the chemistry of double-bonded functional groups were also published in the Series and these volumes contain much material on the chemistry of azoxy compounds. Several subjects were omitted from the original volume in 1975. These omissions have been corrected in the present volume, which contains chapters on "Detection, identification and determination," on NMR, on ESR, on PES, on pharmacology and toxicology, and also on safety and environmental factors.
Hardbound. In this volume, Drs. Parrick and Shaw have upgraded their earlier chapter on pyridazines, cinnolines and Dr Hurst and Dr McCullough have done the same for their chapters on the subjects of pyrimidines and quinazolines and pyrazines, respectively. Dr Bolton has contributed to this series several times before, but not on the subject of phenazine, oxazine and thiazine sulfur dyes. However, his wide experience in heterocyclic chemistry enabled him to analyse recent progress in this area without difficulty and with his customary skill. Professor Johne returns to one of his research interests, quinazoline alkaloids, while Professor O'Shea completes the volume with a timely review of six-membered rings with three or more heteroatoms: triazines, tetrazines, pentazines and hexazines.
Hardbound. This volume begins with two chapters concerned with the chemistry of medium and large heterocyclic rings, including lactones and lactams. This work also explores host-guest relationships within macrocycles embodying oxygen and nitrogen atoms. The authors responsible for bringing together recent progress in the chemistry of this wide assembly of compounds are Dr MacBride and his colleagues Drs Grayson and Kelly. Drs Ewing and McKenzie then survey then survey recent advances in purine chemistry and that of the attendant nucleosides. This chapter naturally leads on to a focused survey of nucleosides and nucleotides. Dr Cosstick contributed a chapter on these major subject areas to the First Supplement and he agreed to review the same subjects in this volume. Professor Pfleiderer is the world's authority on pteridine chemistry and his chapter does more than simply update work on these alkaloids. As a result of his intimate knowledge this author is
Advances in Heterocyclic Chemistry is the definitive series in the field-one of great importance to organic chemists, polymer chemists, and many biological scientists. Because biology and organic chemistry increasingly intersect, the associated nomenclature also is being used more frequently in explanations. Written by established authorities in the field from around the world, this comprehensive review combines descriptive synthetic chemistry and mechanistic insight to yield an understanding of how chemistry drives the preparation and useful properties of heterocyclic compounds.
Porphyrins, composed of four pyrrole subunits, are highly important compounds, which are ubiquitous in biological systems.

This book provides an outline of theoretical concepts and their experimental verification in studies of self-organization phenomena in chemical systems, as they emerged in the mid-20th century and have evolved since. Presenting essays on selected topics, it was prepared by authors who have made profound contributions to the field. Traditionally, physical chemistry has been concerned with interactions between atoms and molecules that produce a variety of equilibrium structures - or the 'dead' order - in a stationary state. But biological cells exhibit a different 'living' kind of order, prompting E. Schroedinger to pose his famous question "What is life?" in 1943. Through an unprecedented theoretical and experimental development, it was later revealed that biological self-organization phenomena are in complete agreement with the laws of physics, once they are applied to a special class of thermodynamically open systems and non-equilibrium states. This knowledge has in turn led to the design and synthesis of simple inorganic systems capable of self-organization effects. These artificial 'living organisms' are able to operate on macroscopic to microscopic scales, even down to single-molecule machines. In the future, such research could provide a basis for a technological breakthrough, comparable in its impact with the invention of lasers and semiconductors. Its results can be used to control natural chemical processes, and to design artificial complex chemical processes with various functionalities. The book offers an extensive discussion of the history of research on complex chemical systems and its future prospects.
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
