Download or read book Modern NMR Approaches to the Structure Elucidation of Natural Products written by Antony Williams and published by Royal Society of Chemistry. This book was released on 2016-12-14 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ghanian plant Cryptolepis sanguinolenta is the source of a series of fascinating indoloquinoline alkaloids. The most unusual member of this alkaloid series was initially proposed to be a spiro nonacyclic structure, named cryptospirolepine, and was elucidated in 1993 based on the technologies available at that time. There were, however, several annoying attributes to the structure that bothered analysts for the ensuing 22 years. During the two decades that followed the initial work there have been enormous developments in NMR technology. Using new experimental approaches, specifically homodecoupled 1,1- and 1,n-HD-ADEQUATE NMR experiments developed in 2014, the structure of only a 700 µg sample of cryptospirolepine has been revised and is shown on the cover of this volume. The confluence of the NMR technological and methodological advances that allowed the revision of the structure of cryptospirolepine using a submilligram sample seems a fitting example for this book, which is dedicated to the NMR characterization of various classes of natural products. Volume 2 considers data processing and algorithmic based analyses tailored to natural product structure elucidation and reviews the application of NMR to the analysis of a series of different natural product families including marine natural products, terpenes, steroids, alkaloids and carbohydrates. Volume 1 discusses contemporary NMR approaches including optimized and future hardware and experimental approaches to obtain both the highest quality and most appropriate spectral data for analysis. These books, bringing together acknowledged experts, uniquely focus on the combination of experimental approaches and modern hardware and software applied to the structure elucidation of natural products. The volumes will be an essential resource for NMR spectroscopists, natural product chemists and industrial researchers working on natural product analysis or the characterization of impurities and degradation products of pharmaceuticals that can be as scarce as natural product samples.

This book was released on 2012-12-06 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contemplation of truth and beauty is the proper object for which we were created, which calls forth the most intense desires of the soul, and of which it never tires -Hazlitt In his Nobel lecture Purcell commented that when he saw snow in New England after the discovery of NMR, it appeared like "heaps of protons quietly precessing in earth's magnetic field. " If he were to make the comment in the context of how NMR is being used today, he could have conjured up an image of hydrogen, carbon, and nitrogen nuclei in proteins of an earthbound 8rganism subtly orchestrating a quiet symphony of frequencies, from 150 Hz to 2 kHz, carrying clues to the three-dimensional structure of the macromolecules. The manner in which the basic discoveries of Bloch and Purcell have led to the emergence of NMR, several decades later, as a major technique of biological and medical physics (and chemistry) is a striking example of the power of basic research. It is also a fascinating saga whereby whenever it was felt that the field had reached a plateau, new directions, new technologies, and sometimes serendipity produced new developments that revolutionized the technique and enhanced its capability. As Richard Ernst points out "NMR is intellectually attractive, . . . the practical importance of NMR is enormous, and can justify much of the playful activities of an addicted spectroscopist" (Nobel lecture).
Download or read book The Nuclear Overhauser Effect written by Joseph Noggle and published by Elsevier. This book was released on 2012-12-02 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nuclear Overhauser Effect aims to provide a unified treatment of both the theory and applications of the NOE that would be accessible to the chemist who is not a specialist in NMR, but who would nevertheless like to use the NOE to solve problems in his own area of interest. Assuming only that the reader has a typical chemist's working knowledge of NMR, an attempt is made to present the results in each section in a sufficiently simple form so that little mathematical sophistication will be required to apply them with understanding. This book comprises eight chapters, and begins with a focus on nuclear spin-lattice relaxation. The following chapters then discuss mechanisms of spin-lattice relaxation; the nuclear overhauser effect in rigid molecules; the effects of internal motions; experimental methods; transient methods; the effects of chemical exchange; and applications of the nuclear overhauser effect, with a review of available literature. This book will be of interest to practitioners in the fields of chemistry and physics.

Download or read book Structure Elucidation by Modern NMR written by Helmut Duddeck and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: For several years, we have been organizing seminars and workshops on the application of modem one and two-dimensional NMR methods at the faculty of chemistry in the Ruhr-University Bochum, FRG, and elsewhere, addressing researchers and graduate students who work in the field of organic and natural products chemistry. In 1987, we wrote a workbook (StrukturaufkUirung mit modemer NMR-Spektroskopie, Steinkopff, Darmstadt, FRG, 1988) in German language based on our experience in these courses. Many of the exercises described therein have been used in such courses and some of them have been shaped by the participants to a great extent. The response of readers and discussions with colleagues from many countries encouraged us two years later to produce an English translation in order to make the book accessible to a wider audience. Moreover, the content has been increased from 20 exercise examples in the German, to 23 in English version. Now, after the rapid development of basic multipulse NMR me thods in the early 1980s, the avantgarde in modem NMR is concentrating on the invention and optimi zation of advanced techniques, e. g. , three-dimensional experiments. For the beginners, however, the situation has not changed markedly since the appearence of the first edition of this book. Therefore, we decided not to add new techniques to this second edition, but rather to increase the number of exerci ses from 23 to 33, the new ones being basically single-spectrum-problems.
Download or read book Lectins and Glycobiology written by Hans-Joachim Gabius and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intriguing complexity, precision, and regulation of the wide range of biologi cal processes is determined by intricate mechanisms of molecular recognition. Their nature is under intense scrutiny. In addition to the well-appreciated interac tion of proteins either with amino acid or nucleotide sequences, the investigation of their interplay with carbohydrate elements of cellular glycoconjugates current ly exerts increasing attraction. In the group of carbohydrate-binding proteins, lec tins are distinguished from antibodies or ligand-affecting enzymes, according to the most recent definition. The thorough analysis of their structure and function is considered as a focus to collect a critical mass of information for delineating details of a further array of biochemical processes with pivotal physiological im pact. Following an already century-long history of scientific description, reflected by subjectively chosen highlights (see the Brief History of Lectin Research at page VI), the excitement in glycobiological research that prevails today can easily be ex plained by our growing awareness of the multifarious significance of a sugar-code system of biological information. This present notion unmistakably has an im pact on lines of research in diverse disciplines like cell and molecular biology, histochemistry, or clinical sciences. It also prompts inherent practical questions such as how to obtain lectins, or how to employ them as instruments in various assay systems with the best possible results. Thus, this book is devoted intentionally to cover the techniques in different research fields that deal with lectins.

Download or read book Dynamics and the Problem of Recognition in Biological Macromolecules written by Oleg Jardetzky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: From within complex structures of organisms and cells down to the molecular level, biological processes all involve movement. Muscular fibers slide on each other to activate the muscle, as polymerases do along nucleic acids for replicating and transcribing the genetic material. Cells move and organize themselves into organs by recognizing each other through macromolecular surface-specific interactions. These recognition processes involve the mu tual adaptation of structures that rely on their flexibility. All sorts of conformational changes occur in proteins involved in through-membrane signal transmission, showing another aspect of the flexibility of these macromolecules. The movement and flexibility are inscribed in the polymeric nature of essential biological macromolecules such as proteins and nucleic acids. For instance, the well-defined structures formed by the long protein chain are held together by weak noncovalent interac tions that design a complex potential well in which the protein floats, permanently fluctuating between several micro- or macroconformations in a wide range of frequencies and ampli tudes. The inherent mobility of biomolecular edifices may be crucial to the adaptation of their structures to particular functions. Progress in methods for investigating macromolecular structures and dynamics make this hypothesis not only attractive but more and more testable.

Download or read book NMR Spectroscopy written by Harald Günther and published by John Wiley & Sons. This book was released on 2013-12-13 with total page 842 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful and widely used techniques in chemical research for investigating structures and dynamics of molecules. Advanced methods can even be utilized for structure determinations of biopolymers, for example proteins or nucleic acids. NMR is also used in medicine for magnetic resonance imaging (MRI). The method is based on spectral lines of different atomic nuclei that are excited when a strong magnetic field and a radiofrequency transmitter are applied. The method is very sensitive to the features of molecular structure because also the neighboring atoms influence the signals from individual nuclei and this is important for determining the 3D-structure of molecules. This new edition of the popular classic has a clear style and a highly practical, mostly non-mathematical approach. Many examples are taken from organic and organometallic chemistry, making this book an invaluable guide to undergraduate and graduate students of organic chemistry, biochemistry, spectroscopy or physical chemistry, and to researchers using this well-established and extremely important technique. Problems and solutions are included.
