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.

Principles of Molecular Recognition

This book was planned with such a development in mind. The book begins with an elementary but rigorous account of the various types of forces between molecules.

The importance of molecular recognition in chemistry and biology is reflected in a recent upsurge in relevant research, promoted in particular by high-profile initiatives in this area in Europe, the USA and Japan. Although molecular recognition is necessarily microscopic in origin, its consequences are de facto macroscopic. Accordingly, a text that starts with intermolecular interactions between simple molecules and builds to a discussion of molecular recognition involving larger scale systems is timely. This book was planned with such a development in mind. The book begins with an elementary but rigorous account of the various types of forces between molecules. Chapter 2 is concerned with the hydrogen bond between pairs of simple molecules in the gas phase, with particular reference to the preferred relative orientation of the pair and the ease with which this can be distorted. This microscopic view continues in chapter 3 wherein the nature of interactions between solute molecules and solvents or between two or more solutes is examined from the experimental standpoint, with various types of spectroscopy providing the probe of the nature of the interactions. Molecular recognition is central to the catalysis of chemical reactions, especially when bonds are to be broken and formed under the severe con straint that a specific configuration is to result, as in the production of enan tiotopically pure compounds. This important topic is considered in chapter 4.

Design and Synthesis of Organic Molecules Based on Molecular Recognition

The receptor-agonist interaction has been likened to the association of enzymes with their substrates or allosteric effectors [2] and similar molecular recognition mechanisms implied, especially an induced complementary fit that ...

A topic for a Solvay Conference should be general enough to conform with the great tradition of previous conferences. On the other hand it should not be so broad that it can not be covered during the limited time of the conference. After discussion of several such topics, "Design and Synthesis of Organic Molecules Based on Molecular Recognition" was chosen. According to Albert Einstein we live in an era of perfect methods and confused aims. For example in organic chemistry the known synthetic methods allow us to prepare an astronomical number of compounds; the gap between the possible and the relevant becomes larger every day. After discovery and classification of the main types of reactions, the study of the selectivity of reactions becomes of paramount importance. One can learn quite a lot from Nature, which uses molecular recognition to achieve selec tivity in a degree so far unattainable by mere mortals. To analyze the structural features applied by Nature, to accomplish high molecular recog nition, and to simulate these features by synthesis have recently become therefore favorite occupations of chemists. The purpose of this conference was to bring together two groups, the analysts and the syntheticists, to discuss the present status of the knowledge. This monograph contains the chairman's introduction in which he has summarized the main points at issue and the contributions of the renowned scientists who participated. The organizers hope that it will stimulate further research in this fascinating field.

Supramolecular Chemistry of Biomimetic Systems

This molecular tuning strategy may be capable to create molecular recognition sites better than those of standard biological systems. In Fig. 3.6, major types of molecular recognition mechanisms are historically categorized [20].

This book investigates the latest developments in supramolecular assembly systems for mimicking biological structures and functions. Consisting of 14 chapters, it covers various assembly systems, such as polysaccharides, peptides, proteins, biopolymers, natural materials and various hybrid systems. Further, it focuses on different types of supramolecular systems with particular functions or structures that are relevant to living systems. A number of modern techniques used to study the supramolecular systems, such as total internal reflection fluorescence microscopy (TIRFM) and two-photon confocal microscopy, are also introduced in detail. Unlike conventional books on supramolecular assemblies, this book highlights the functions of the assembly systems, particularly their biological applications. As such, it offers a valuable resource for experienced researchers, as well as graduate students working in the field of supramolecular chemistry and biomimetic systems.
