This book focuses on the new and old methods for the synthesis of various heterocycles using Lawesson's reagent. The book covers an important and rapidly growing branch of heterocyclic chemistry and can serve as a guide to those who are completing their education and are about to enter the job market. Students will be able to find all Lawesson's reagent-assisted protocols for the synthesis of heterocycles in one place. This feature of the book provides an important benefit, because sometimes users want to see all the possibilities and relevant information for making a particular compound using one particular reagent. The purpose of this valuable resource is to provide the knowledge not only to students but also to pharmacologists, biochemists, organic and medicinal chemists, researchers, and academic professionals for easy access to synthetic protocols for different heterocycles using Lawesson's reagent. The book will be greatly helpful for everyone involved inthe field and can pave the way for better understanding and quantification of heterocycle synthesis.

The chemical study of insects has been growing for four decades, and with it an interest in how insects make their pheromones, hormones, defensive secretions, venoms, pigments and surface coverings. By investigating the biosynthesis of insects, one can gain a greater insight into the structure and function of insect compounds, into ways of disrupting biosynthetic reactions in pest species and how these pathways evolved. The first textbook of its kind, Biosynthesis in Insects amalgamates previously fragmented information and recent exciting developments in the field to provide a unique, concise chemical study of how insect substances are biosynthesised. This book provides a comprehensive introduction to the ways that have been investigated, by which a great variety of insects, and some related arthropods, make their so-called secondary metabolites. Simpler biosynthetic pathways are explored before considering the experimental methods by which these studies are conducted. Consideration is also given to some of the plant substances which insects store or metabolize to their own use. Abundantly illustrated with structures and reactions, and some beautiful photographs, Biosynthesis in Insects includes a series of problems and answers to facilitate and assess learning, making this unique look at biosynthesis in insects and their near relations ideal for students with some chemical background starting out on a study of insect substances. Researchers and academics will also welcome the amalgamation of previously scattered information. Including an index of compounds and species, and lists for further reading, this book provides a truly unique source for those working in the field.

Metabolic inhibitors and receptor antagonists are indispensable tools for the molecular life scientist. By blocking specific enzymes or receptor-mediated signal transduction cascades, they simplify the analysis of complex cellular processes especially when it is essential to demonstrate that a process of interest is functionally linked to a particular enzyme or receptor. From antibiotics to statins, modern medicine relies on the reliability and ease-of-use of enzyme- and receptor-directed inhibitors and antagonists.The Inhibitor Index is a comprehensive, curated compendium of over 7,800 enzyme inhibitors and receptor antagonists, including many toxins, poisons, and metabolic uncouplers.

While some of the most commonly investigated- and most notorious- chemicals in the world are alkaloids, many modern medicines are also based on alkaloid structures. Chemists continue to explore new synthetic routes and alkaloid derivatives in search of drug candidates for fighting disease. Drawn from the venerable Dictionary of Natural Products, th

The need for information in the understanding of membrane systems has been caused by three things - an increase in computer power; methodological developments and the recent expansion in the number of researchers working on it worldwide. However, there has been no up-to-date book that covers the application of simulation methods to membrane systems directly and this book fills an important void in the market. It provides a much needed update on the current methods and applications as well as highlighting recent advances in the way computer simulation can be applied to the field of membranes and membrane proteins. The objectives are to show how simulation methods can provide an important contribution to the understanding of these systems. The scope of the book is such that it covers simulation of membranes and membrane proteins, but also covers the more recent methodological developments such as coarse-grained molecular dynamics and multiscale approaches in systems biology. Applications embrace a range of biological processes including ion channel and transport proteins. The book is wide ranging with broad coverage and a strong coupling to experimental results wherever possible, including colour illustrations to highlight particular aspects of molecular structure. With an internationally respected list of authors, its publication is timely and it will prove indispensable to a large scientific readership.

Expert systems allow scientists to access, manage, and apply data and specialized knowledge from various disciplines to their own research. Expert Systems in Chemistry Research explains the general scientific basis and computational principles behind expert systems and demonstrates how they can improve the efficiency of scientific workflows

Traditionally, the search for new compounds from natural products has been a time- and resource-intensive process. The recent application of combinatorial methods and high-throughput synthesis has allowed scientists to generate a range of new molecular structures from natural products and observe how they interact with biological targets. Combinato

When introduced to the human body, bioactive metabolites produced by plants for self defense bind to particular biochemical targets, most notably to proteins involved in signaling by hormones and neurotransmitters. This, essentially, is the basis for the effects of herbal medicine. While herbal medicine preparations may act by complex synergistic i

The Porphyrin Handbook, Volume 20: Phthalocyanines: Structural Characterization provides information pertinent to every aspect of the chemistry, synthesis, spectroscopy, and structure of phthalocyanines. This book examines the biology and medical implications of porphyrin systems. Organized into one chapter, this volume begins with an overview of the molecular and crystal structures of phthalocyanine and related complexes followed by a database section. This text then examines the crystallographic data that provided many researchers with the foundation to conduct their own research on phthalocyanine crystal structures. This book considers the structural basis for the prediction or calculation of the phthalocyanine physical properties. This book discusses as well the fundamental structure of a phthalocyanine molecule that consists of four isoindole units, circularly linked via azamethine bridges. This book is a valuable resource for research scientists, engineers, and clinicians.
