Available in PDF, EPUB and Kindle. Book excerpt: One of the most active areas of contemporary organic chemistry involves the search for new catalysts that borrow concepts, strategies and even components from enzymes but yet are not found in nature. Such artificial enzymes not only give enormous insights into the mechanisms of enzyme catalysis but also offer the potential for catalyzing a wide range of chemical reactions with no counterpart in nature. Several approaches have been taken in the deVelopment of new catalysts, some based on biological methods and others on synthetic techniques. Site directed mutagenesis has allowed the direct replacement of amino acids in an enzyme with resulting changes in stability, selectivity and mechanism. Recent developments have shown that even non-natural amino acids can be incorporated into proteins and also that enzymes can function effectively in organic solvents. A different biological route to artificial enzymes has exploited the immune system and its ability to generate millions of antibodies to a given antigen. Novel antigens have been designed to mimic the transition states of chemical reactions. Antibodies elicited against these antigens thus contain an active site that is complementary to transition state structure and can potentially catalyze target reactions. A broad range of reactions can now be 6 catalyzed using the method with rate accelerations reaching 10 compared to the control reactions. Protein engineering and catalytic antibodies represent complex solutions to the problem of artificial enzymes. Their complexity is however their principal limitation.

This book was released on 2012-12-06 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: In current thinking, Bioorganic Chemistry may be defined as the area of chemistry which lies in the border region between organic chemistry and biology and which describes and analyzes biological phenomena in terms of detailed molecular structures and molecular mechanisms. This molecular-level view of biological processes is not only essential to their fuller understanding but also serves as the platform for the application of the principles of such processes to areas of health care and technology. The objective of the ASI workshop on " Bioorganic Chemistry in Healthcare and Technology", held in the Hengelhoef Congress Centre in Houthalen-Helchteren, Belgium, from September 18-21, 1990, was to bring together most of the international experts in the field to discuss the current developments and new trends in bioorganic chemistry, especially in relation to the selected theme. The book presents nineteen invited plenary and session lectures and eighteen posters. These cover areas of (i) molecular design of therapeutic and agronomical agents based npon mechanistic rationale or drug-receptor interactions, (ii) production of substances of commercial value via combined organic chemical and bio-chemical methodologies, (iii) fundamental studies on the molecular mechanisms of enzymes and (iv) the evolution of conceptually new molecular systems which are programmed to execute specific recognition and/or catalytic functions. An abstracted version of the plenary discussion held at the end of the workshop is also included. We feel confident that the subject matter of this book will be of interest to a broad group of chemists engaged in academic or industrial research.

Download or read book Supramolecular Catalysis written by Piet W. N. M. van Leeuwen and published by John Wiley & Sons. This book was released on 2008-06-25 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few years, supramolecular chemistry has led to new approaches in homogeneous catalysis. While host-guest chemistry had already found applications in catalysis as a result of the pioneering work carried out by Professor Ronald Breslow and Nobel prizewinner Professor Jean-Marie Lehn that began some 40 years ago, the construction of catalysts by supramolecular forces has only recently become a powerful tool. This development paves the way for large numbers of new potential catalysts that can be varied in an expedient way by changing the constituting building blocks. Written by some of the leading contributors in the field, this book is intended for both industrial and academic chemists with an interest in this area of catalysis. With its discussion of topics from ligand libraries to chirality-directed self-assembly, this is a must-have for chemists with organic, catalytic and polymer backgrounds, as well as those employing such compounds in industrial processes.

This book was released on 2012-12-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the broad field of supramolecular chemistry, the design and hence the use of chemosensors for ion and molecule recognition have developed at an extroardinary rate. This imaginative and creative area which involves the interface of different disciplines, e.g. organic and inorganic chemistry, physical chemistry, biology, medicine, environmental science, is not only fundamental in nature. It is also clear that progress is most rewarding for several new sensor applications deriving from the specific signal delivered by the analyte-probe interaction. Indeed, if calcium sensing in real time for biological purposes is actually possible, owing to the emergence of efficient fluorescent receptors, other elements can also be specifically detected, identified and finally titrated using tailored chemosensors. Pollutants such as heavy metals or radionuclides are among the main targets since their detection and removal could be envisioned at very low concentrations with, in addition, sensors displaying specific and strong complexing abilities. Besides, various species of biological interest (or others, the list is large) including sugars and other micellaneous molecules such as oxygen and carbon dioxide can be actually probed with optodes and similar devices. The present volume in which the key lectures of the workshop are collected gives a survey of the main developments in the field. The success of the workshop mainly came from the high quality of the lectures, the invited short talks, the two posters sessions and the many very lively discussions which without doubt will produce positive outcomes.
Download or read book Redesigning the Molecules of Life written by Steven A. Benner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: The organic chemist is rarely satisfied by a simple "explanation" of the reactivity of organic molecules. Rather, the chemist wants to go one step further, to "control" the behavior of molecules by altering their structure in a controlled way. This is, in fact, a rather stringent definition of "understanding," as it requires the "prediction" of behavior from structure (or structure from behavior). But it also places technical demands on the chemist. He must be able to synthesize the molecules he studies, characterize them at the atomic level of structural resolution, and then measure their behaviors to the precision that his explanation demands. Biological chemistry presents special problems in this regard. Although the tools for synthesis, purification, and structural characterization are now available for manipulating rather large biological macromolecules (proteins and nucleic acids in particular), the theory supporting these manipulations is inadequate. We certainly do not know enough to control generally the behavior of biological macromolecules; still worse, it is not clear that we know enough to design synthetic molecules to expand our understanding about how reactivity in such biological macromolecules might be controlled. Starting from scratch, there are simply too many oligopeptides to make; starting from native proteins, there are simply too many structural mutations that might be introduced.

Download or read book Current Challenges on Large Supramolecular Assemblies written by Georges Tsoucaris and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of the ARW were: - identifying areas and highlighting approaches by which large Supramolecular (SM) Assemblies can be synthesised - reviewing and combining methods to characterise and analyse such assemblies. The first part of the ARW is devoted to reviewing synthetic achievements in recent years for several families of SM compounds, and to bringing out principles for crystal structure design, including novel quantum mechanical methods. Synthesis pertains both to the chemical synthesis of components for SM assembly, and to the subsequent assembly process based on complementarity and non-covalent interactions. The elaboration of multiple recognition "algorithms" concurrently employed (for instance, 1t-1t and hydrogen bonds) has recently reached a high degree of sophistication in the sequence: Molecules -7 Supermolecule -7 SM array -7 Crystal or Conglomerate Novel Large Assemblies comprise synthetic entities with molecular weight as high as 15000, and hybrid SM assemblies between synthetic molecules and DNA. Further developments are foreseen at a higher level of organisation, such as between supermolecules or with electromagnetic fields in photochemical processes. Creation of 2D Assemblies is now a powerful tool for creation and study of SM interactions. Moreover, much is to be learned in going from 2D to 3D assemblies in crystal growth and other forms of organisation such as micelles or liquid crystals. On the other hand, crystal engineering based on Molecular Recognition in the Crystal State leads to novel 2D assemblies occurring within predesigned crystal structures (hydrophobic organic clays or nanoporous networks).
Download or read book Magnetism A Supramolecular Function written by O. Kahn and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular magnetism is a new field of research dealing with the synthesis and study of the physical properties of molecular assemblies involving open-shell units. It is essentially interdisciplinary, joining together organic, organometallic and inorganic chemists, as well as theoreticians, physicists and materials scientists. At the core of research into molecular magnetism lie design and synthesis of new molecular assemblies exhibiting bulk properties such as long-range magnetic ordering or bistability with an hysteresis effect, which confers a memory effect on the system. In such terms, magnetism may be considered a supramolecular function. The first eight contributions to this volume present the state of the art in organic supramolecular chemistry, emphasising interlocked systems and molecular trees. The following six articles are devoted to molecular materials constructed from organic radicals and transition metal units. Molecular bistability is then focused on, followed by metal-organic and coordination magnetic materials. A new approach to nano-sized particles closes the work.
