Basics Of Molecular Recognition

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.

The book begins with the types of bonds that participate in the recognition and the functional groups that are capable of forming these bonds. It then explains how smaller molecules select their partners in the overall recognition scheme, offering examples of specific recognition patterns involving molecules other than nucleic acids. The core of the book focuses on macromolecular recognition the central dogma of molecular biology. The author discusses various methods for studying molecular recognition. He also describes how molecules without biological functions can be arrayed or folded following certain rules and examines the nature of interactions among them.

Basics of Molecular Recognition explores fundamental recognition principles between monomers or macromolecules that lead to diverse biological functions. Based on the author's longtime courses, the book helps readers understand the structural aspects of macromolecular recognition and stimulates further research on whether molecules similar to DNA o

Reasoning in terms of molecular recognition may be traced back to Emil Fischer, who practiced the art of chemistry at Humboldt University in Prussian Berlin a century ago. Today, it is clearly recognized that molecular recognition impacts and determines all life processes. It has become a key research field in both chemistry and biology and the emerging interface of what now is being called "chemical biology". The technological advances derived from this knowledge are particularly important, diverse, and directly evident in the pharmaceutical industry. Under the auspices of the Ernst Schering Research Foundation, a workshop held in Berlin in February 1998 addressed novel basic developments of potential relevance to drug research efforts. A balance of timely research topics in molecular recognition is presented in the lectures delivered by a multidisciplinary international panel of renowned scholars and documented in this volume.

The lock-and-key principle formulated by Emil Fischer as early as the end of the 19th century has still not lost any of its significance for the life sciences. The basic aspects of ligand-protein interaction may be summarized under the term 'molecular recognition' and concern the specificity as well as stability of ligand binding. Molecular recognition is thus a central topic in the development of active substances, since stability and specificity determine whether a substance can be used as a drug. Nowadays, computer-aided prediction and intelligent molecular design make a large contribution to the constant search for, e. g., improved enzyme inhibitors, and new concepts such as that of pharmacophores are being developed. An up-to-date presentation of an eternally young topic, this book is an indispensable information source for chemists, biochemists and pharmacologists dealing with the binding of ligands to proteins.

Document from the year 2018 in the subject Chemistry - Analytical Chemistry, grade: Ist, , course: Chemical Sciences, language: English, abstract: Owing to the boom of Industrialization and modernization, diverse chemical entities have found entrance into various environmental components. Thus the continous monitoring of environment has been a crucial issue to the community. In this regard, development of novel technologies have urged a surge in the recent past. Among the various approaches proposed by the researchers, supramolecular chemistry has came up with intelligent state of art molecules know as " Receptors". These can be organic or inrganic moities which secreen the diverse chemical environments through visual display. They possess immense potential to overcome the diffculties associated with exisiting bulky and tedious strategies for environmental monitoring. In this book chapter, we have tried to present an introduction to this molecular approach for sensing of various chemical species in the form of caion and anions. The basic classification of the molecular receptor approach has been introduced. This has been further exaplained via the mechanism of intraction between molecule and analyte durring the course of sensng in diverse environmental matrices.
