Book Description
In the monograph, recognition of the receptors by drugs is described as a complex phenomenon that has not been yet entirely understood. The description of molecular structure information necessary to achieve specific receptors without getting lost among huge amounts of non-specific acceptors is present. Various examples of receptor' binding features for narcotic analgetics, neuroleptics, tranquilisators, ligands of acetylcholine receptors are also included. The three stages of drug interaction with acceptors are considered, namely, distant stage, stage of orientation of the molecule on the acceptor, stage of molecule fixation. Kinetics and thermodynamics of these stages as well as factors preventing drug binding to non-specific acceptors are described. Some considerations concerning methods of changing activity and selectivity of drugs are given. Literature information needed for analysis of molecular mechanisms of interactions between drugs and receptors is present.

Book Description
This unique volume traces the behavior of the drug substance, starting from the initial pre-contact stage, and ending with the formation of the complex. Molecular recognition lies in the foundation of every life form and includes many mysteries. Currently, studies on this topic in pharmacology are limited to determining the properties of complexes of medicinal substances (drugs) with specific (complementary) biomolecules: receptors, enzymes, ion channels etc. The results present the mechanisms preventing drugs from such non-specific binding. This direction is very fruitful, although the phenomenon of molecular recognition is far wider. Features Presents the basics of thermodynamics and kinetics of complex formation between ligands and receptors Selected novel therapeutic concepts are tested and validated Provides a review of the pharmacophore approach and drug design methods By its nature, pharmacology is a multi-disciplinary science, hence, disciplinary areas include chemistry, biology and neuroscience Discusses hot topics including 3D structure determination techniques and in silico methods and neural networks The main theme of the book is the consideration of mechanisms created by nature to protect physiologically active substances from being stuck on nonspecific acceptors in the body. The book describes the materials that aid in the development of new medicinal substances. It is intended for researchers, as well as upper-level undergraduate and graduate students interested in the problems of molecular pharmacology and drug design.

Book Description
The sustainable use of natural resources is an important global challenge, and improved metal sustainability is a crucial goal for the 21st century in order to conserve the supply of critical metals and mitigate the environmental and health issues resulting from unrecovered metals. Metal Sustainability: Global Challenges, Consequences and Prospects discusses important topics and challenges associated with sustainability in metal life cycles, from mining ore to beneficiation processes, to product manufacture, to recovery from end-of-life materials, to environmental and health concerns resulting from generated waste. The broad perspective presented highlights the global interdependence of the many stages of metal life cycles. Economic issues are emphasized and relevant environmental, health, political, industrial and societal issues are discussed. The importance of applying green chemistry principles to metal sustainability is emphasized. Topics covered include: • Recycling and sustainable utilization of precious and specialty metals • Formal and informal recycling from electronic and other high-tech wastes • Global management of electronic wastes • Metal reuse and recycling in developing countries • Effects of toxic and other metal releases on the environment and human health • Effect on bacteria of toxic metal release • Selective recovery of platinum group metals and rare earth metals • Metal sustainability from a manufacturing perspective • Economic perspectives on sustainability, mineral development, and metal life cycles • Closing the Loop – Minerals Industry Issues The aim of this book is to improve awareness of the increasingly important role metals play in our high-tech society, the need to conserve our metal supply throughout the metal life cycle, the importance of improved metal recycling, and the effects that unhindered metal loss can have on the environment and on human health.

Book Description
Over the past 25 years, the molecular electrostatic potential has become firmly established as an effective guide to molecular interactions. With the recent advances in computational technology, it is currently being applied to a variety of important chemical and biological systems. Its range of applicability has expanded from primarily a focus on sites for electrophilic and nucleophilic attack to now include solvent effects, studies of zeolite, molecular cluster and crystal behavior, and the correlation and prediction of a wide range of macroscopic properties. Moreover, the increasing prominence of density functional theory has raised the molecular electrostatic potential to a new stature on a more fundamental conceptual level. It is rigorously defined in terms of the electron density, and has very interesting topological characteristics since it explicitly reflects opposing contributions from the nuclei and the electrons.This volume opens with a survey chapter by one of the original pioneers of the use of the electrostatic potential in studies of chemical reactivity, Jacopo Tomasi. Though the flow of the succeeding chapters is not stringently defined, the overall trend is that the emphasis changes gradually from methodology to applications. Chapters discussing more theoretical topics are placed near the end. Readers will find the wide variety of topics provided by an international group of authors both convincing and useful.

Book Description
Of the three basic states of matter, liquid is perhaps the most complex. While its flow properties are described by fluid mechanics, its thermodynamic properties are often neglected, and for many years it was widely believed that a general theory of liquid thermodynamics was unattainable. In recent decades that view has been challenged, as new advances have finally enabled us to understand and describe the thermodynamic properties of liquids. This book explains the recent developments in theory, experiment and modelling that have enabled us to understand the behaviour of excitations in liquids and the impact of this behaviour on heat capacity and other basic properties. Presented in plain language with a focus on real liquids and their experimental properties, this book is a useful reference text for researchers and graduate students in condensed matter physics and chemistry as well as for advanced courses covering the theory of liquids.

Book Description
The fundamentals of "supramolecular chemistry" to the latest developments on the subject are covered by this book. It sets out to explain the topic in a relatively easy way. The basic concepts of molecular recognition chemistry are included. Molecules with fascinating shapes and functions such as fullerenes, carbon nanotubes, dendrimers, rotaxane, and catenane, and molecular assemblies are also explained. Thereafter applications of supermolecules to nanotechnology are introduced with many examples of molecular devices. The last part of the book describes biological supermolecules and their mimics. Though simply explained undergraduate and graduate students in Chemistry will be able to use aspects of this work as an advanced textbook.

Book Description
Cyclophanes are bridged aromatic compounds and represent the central class of synthetic receptors in molecular recognition. All types of substrates, from inorganic and organic cations and anions, to neutral molecules have been complexed by tailor-made cyclophanes. This monograph focuses on the principles of supramolecular complexation and catalysis. It provides a state-of-the-art review of the intermolecular forces that hold together the supramolecular complexes of cyclophanes with neutral and charged organic molecules in the liquid phase. Cyclophanes also demonstrates the characteristics and advantages of bridged aromatic compounds as receptors. The book has great clarity, is very readable and will be extremely useful in both teaching and research.

Book Description
Comprehensive Supramolecular Chemistry II, Second Edition, Nine Volume Set is a ‘one-stop shop’ that covers supramolecular chemistry, a field that originated from the work of researchers in organic, inorganic and physical chemistry, with some biological influence. The original edition was structured to reflect, in part, the origin of the field. However, in the past two decades, the field has changed a great deal as reflected in this new work that covers the general principles of supramolecular chemistry and molecular recognition, experimental and computational methods in supramolecular chemistry, supramolecular receptors, dynamic supramolecular chemistry, supramolecular engineering, crystallographic (engineered) assemblies, sensors, imaging agents, devices and the latest in nanotechnology. Each section begins with an introduction by an expert in the field, who offers an initial perspective on the development of the field. Each article begins with outlining basic concepts before moving on to more advanced material. Contains content that begins with the basics before moving on to more complex concepts, making it suitable for advanced undergraduates as well as academic researchers Focuses on application of the theory in practice, with particular focus on areas that have gained increasing importance in the 21st century, including nanomedicine, nanotechnology and medicinal chemistry Fully rewritten to make a completely up-to-date reference work that covers all the major advances that have taken place since the First Edition published in 1996
