Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued.
Download or read book Specificity in Plant Diseases written by R. Wood and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NATO Advanced Study Institute on "Phytotoxins in Plant Diseases" was held in Pugnochiuso (Italy) in June 1970. It was concerned mainly with the chemistry and mode of action of substances toxic to higher plants which are produced by pathogenic bacteria and fungi. The role of such substances in specificity was consider ed but largely in relation to host-specific toxins. In 1973, in light of the success of the 1970 Institute, we decided to plan for another in 1975 and after discussion with col leagues during the Second International Congress of Plant Pathology, we selected "Specificity in Plant Diseases" as the theme for the 1975 Institute. Our chief reasons for the choice were that specificity is un doubtedly the dominant problem in plant pathology and that with the rapid increase during the last decade or so in the diversity and sophistication of biochemical techniques, we should now expect during the next few years much more research on specificity and major ad vances in our understanding of the mechanisms that control it. It seemed to us that a residential meeting with the advantages and status of a NATO Advanced Study Institute would do much to stimulate interest and research in this most important field. The theme also had the merit of continuity with that of the 1970 Institute.

This book was released on 2012-12-06 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Isocoumarins have been isolated from a wide variety of microbial, plant and insect sources and have been shown to possess an impressive array of biological activities. Since the review by BARRY in 1963 (24), the number of known naturally occurring isocoumarins has increased dramatically. This increase is largely due to improvements in isolation procedures and structural analysis. Previous reviews have concentrated on fungal isocoumarins (293,294) and mycotoxic isocoumarins (301). This review lists over 160 naturally occurring isocoumarins. Leading references on isolation, structure elucidation, biosynthesis and synthesis are given in the accompanying Tables. The known natural isocoumarins are listed in the Tables according to the number and orientation of oxygen atoms on the benzenoid ring and by carbon substituents. For completeness, those isocoumarins bearing additional fused carbocyclic rings and those containing nitro gen substituents are included in separate Tables. It is hoped that by using these Tables in conjunction with the Formula Index, the Trivial Name Index and the Source Index the reader will be able to locate key references in the literature and gain an understanding of the fascin ating chemistry and action of naturally occurring isocoumarins.

Download or read book The Biosynthesis of Secondary Metabolites written by R.B. Herbert and published by Springer Science & Business Media. This book was released on 1989-03-31 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chief purpose of such new editions is to bring the text up to date. This I have tried to do. The danger with such endeavours is that the book becomes corpulent. This I have tried to avoid. In so doing I am evermore conscious of how much material has had to be omitted. As before the references (ca. 770 of them) which are cited are intended in part to provide the reader with access to material that has been omitted. I am deeply grateful to Mrs Marjorie Romanowicz for preparing the typed manuscript for this edition with customary accuracy and efficiency, to my wife Margaret for checking the references, and to research students Karl Cable, Lucy Hyatt, Mashupye Kgaphola and Andrew Knaggs for helping with the checking of the manuscript. Richard Herbert April 1988 Preface to the first edition This is a book about experiments and results of experiments. The results described are the fruit of thirty years' labour in the field of secondary metabolism. Secondary metabolism, more than any other part of the chemistry of life, has been the special preserve of organic chemists. Investigation of secondary metabolism began with curiosity about the structures of compounds isolated from natural sources, i.e. secondary metabolites. Coeval with structure determination there has been a curiosity about the origins and mechanism of formation of secondary metabolites (or natural products as they have been called). It is the experimental outcome of this curiosity that is described here.

Download or read book The Biosynthesis of Mycotoxins written by Pieter Steyn and published by Elsevier. This book was released on 2012-12-02 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biosynthesis of Mycotoxins: A Study in Secondary Metabolism focuses on the biosynthetic analysis of mycotoxins, which are inherently a heterogeneous group of metabolites that are formed along the terpene route and the route polyketide, as well as from amino acids. This book discusses the unique biological properties and structural complexity of the highly specialized secondary microbial metabolites. Organized into 12 chapters, this book starts with an overview of the characteristics of secondary metabolites, including their problematic function and the combination of their structural diversity with their restricted biological occurrence. This text then explains the sporadic occurrence of the mycotoxins as fungal metabolites. Other chapters explore ergochromes, which are a group of light yellow mycotoxins that are isolated from ergot, mold fungi, and lichens. The final chapter discusses the biosynthesis of several unrelated fungal metabolites for which toxicological data are reported. Biochemists, organic chemists, mycologists, enzymologists, plant pathologists, toxicologists, and graduate students will find this book useful.
Download or read book Carbon 13 NMR Spectroscopy written by J Stothers and published by Elsevier. This book was released on 2012-12-02 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon-13 NMR Spectroscopy focuses on the potential of 13C techniques and the practical difficulties associated with the detection of 13C NMR absorption. This monograph includes a descriptive presentation of 13C shielding results that has been adopted with emphasis on the structural and stereochemical aspects. Organized into four parts encompassing 11 chapters, this book starts with an overview of the characteristics of the NMR signals derived from compounds containing 13C nuclei in natural abundance that are inherently much weaker than those exhibited by protons. This monograph then compares the primary characteristics of 13C NMR with the more familiar proton methods. Other chapters consider the 13C spectra of pyridine, pyridazine, pyrimidine, pyrazine, s-triazine, and s-tetrazine. The final chapter deals with the effects of solute–solvent interactions on the shieldings of other nuclei. This monograph is intended for organic chemists, graduate students, and researchers in various branches of chemistry with an interest in 13C NMR methods as another approach to chemical problems.
