This book was released on 2013-03-11 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 7 of Alkaloids: Chemical and Biological Perspectives appears under the aegis of a new publisher: the distinguished firm of Springer Verlag New York, Inc. This volume presents three timely reviews on alkaloids: Chapter 1 reviews the homoerythrina and related alkaloids. a group of compounds occurring in seventeen species that are native to countries bordering the western Pacific. Since the last review in 1981, the number of these alkaloids has doubled. Chapter 2 is a comprehensive review of the carbon-13 NMR spectros copy of steroidal alkaloids. Because more than 350 plant species have yielded steroidal alkaloids and these alkaloids exhibit a wide spectrum of biological activities, including teratogenicity, this catalog of spectral and physical data should prove very useful to workers in this field. Chapter 3 presents a detailed review of proton and carbon-I3 NMR shift assignments and physical constants of norditerpenoid alkaloids. This chap ter is an extensive supplement to the review that appeared in Volume 2 of this series. In addition to the catalog of spectral and physical data, this chapter includes tables of proton and carbon shift assignments, a table of the occurrence of alkaloids in plant species, an index of al1 X-ray crystal structure determinations of norditerpenoid alkaloids, and tables containing molecular formulas versus calculated high-resolution mass values and calculated high-resolution mass values versus molecular formulas of nor diterpenoid alkaloids. Each chapter in this volume has been reviewed by an expert in the field. Indexes for both subjects and organisms are provided.

Book excerpt: 'Natural Compounds: Plant Sources, Structure and Properties' details the properties of over 7,500 chemical compounds of pharmacological interest found in plants. Each volume systematically covers occurrence of the compounds in plants, illustrations of chemical structures plus physical-chemical, spectral, and pharmacological data. Entries are indexed by plant name, subject, and pharmacological property. This provides unique coverage of information on compounds isolated from some 3,000 plants, including many from central Asia and Russia, that are not well known elsewhere. The entries for each compound share a similar format. The entries are preceded by tabulated information on the occurrence of the compounds in plants etc. The highly experienced team of compilers from the renowned Institute of the Chemistry of Plant Substances in Tashkent have expertly assessed the international literature and include data only when confident of its validity, e.g. excluding data where measurement processes cause degradation of the original compound.

Download or read book Plant Alkaloids written by Lyle E Craker and published by Routledge. This book was released on 2018-12-19 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant Alkaloids: A Guide to Their Discovery and Distribution serves as a record of both the positive and negative results obtained in the screening of more than 20,000 plant species for alkaloids in a forty-year search for new medicinal agents and other pharmacological substances. Designed to increase general knowledge of the Plant Kingdom, this book equips present and future generations of phytochemists with the skills and knowledge necessary for developing new alkaloid compounds. Recording the results of screening tests from approximately 400 genera of plants found primarily in zones beneath 45? N Latitude, Plant Alkaloids contributes to the efforts to calculate and safeguard the resources of the rainforests of the world. By offering results `from the field,'Plant Alkaloids surpasses the tradition of books on alkaloid chemistry that only emphasize the chemical and physical properties of known compounds, their established structures, biogenetic origins, taxonomic usefulness, and pharmacological actions. These results, in many cases, constitute the first record of the probable presence of alkaloids in the species under study. By documenting both positive and negative results, Plant Alkaloids directs the search for potentially new and useful compounds, while alleviating much of the time and expense of screening plants where results have already been obtained.An invaluable reference book for scientists in any of the life sciences, Plant Alkaloids provides a general index containing references to standard works on alkaloid chemistry and the subject?s vast literature. In addition to offering a description of the size of each plant family and its economic importance, this book also lists the genera and species of each plant tested according to accepted taxonomic names and notes disagreement over taxonomic assignment where it exists.

Available in PDF, EPUB and Kindle. Book excerpt: Alkaloids: Chemical and Biological Perspectives, the 15th volume of the ACBP series, features four important reviews of research on alkaloids. Chapter 1 is the first comprehensive review of the carbon-13 and proton NMR shift assignments and physical constants of diterpene alkaloids and their derivatives. In addition to the catalogue of spectral and physical data, the chapter includes a table of the occurrences of these alkaloids in various plant species, tables containing molecular formulas versus calculated high-resolution mass values, and calculated high-resolution mass values versus the molecular formulas of diterpenoid alkaloids, as well as seven tables summarizing the carbon-13 chemical shifts of various functional groups in diterpenoid alkaloids. Chapter 2 is a fascinating review of the supercritical fluid extraction of alkaloids. This technique using basic modifiers, provides an alternative method for the extraction of alkaloids. Chapter 3 summarizes recent advances in the synthesis of Amaryllidaceae alkaloids, an important class of naturally-occurring bases and neutral compounds. The increased activity in the synthesis of these alkaloids over the last decade is undoubtedly due to the fact that certain members of this family possess interesting and useful biological properties. Elegant syntheses, chiral and otherwise, of structures incorporating many asymmetric centres are reviewed. Chapter 4 reviews radical cyclization reactions in the total synthesis of indole alkaloids. The use of free radical chemistry in the synthesis of alkaloids has grown markedly because of the mild reaction conditions, tolerance of a wide variety of functional groups, and the good stereoselectivities. Each chapter in this volume has been reviewed by at least one specialist in the field.

Download or read book The Alkaloids written by M F Grundon and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 288 pages. 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 Alkaloids Chemical and Biological Perspectives written by S.W. Pelletier and published by Elsevier. This book was released on 2000-02-14 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 14 of this series presents three interesting reviews of research on alkaloids. Chapter 1, by Paul L. Schiff, Jr., is a monumental effort, presenting a selective, comprehensive tabular review of research on the bisbenzylisoquinoline alkaloids, with an analysis of the respective alkaloid types. The chapter should serve as a very useful tool for the bench research scientist who is involved in the isolation and elucidation of structures of bisbenzylisoquinoline alkaloids. Moreover, the data in these tables provides the botanical distribution and occurrence (family, genus, species) of the various classes of these alkaloids. The alkaloids are also categorized by their molecular weights and structural types. Chapter 2, by Toh-Seok Kam, is a review of alkaloids derived from Malaysian flora. Malaysia's position near the Equator confers on it a tropical climate characterized by high temperatures, humidity, and rainfall, conditions favorable for plant life that has resulted in a rich flora of about 15,000 species of higher plants. This review concentrates on work published during the past twenty years and where appropriate compares the occurrence of alkaloids with studies of similar plants from countries neighboring to Malaysia, especially Thailand and Indonesia. Chapter 3, by Jie Jack Li, presents a collection of very interesting total syntheses of naturally occurring indole alkaloids where palladium chemistry plays a central role in the syntheses. Five different types of palladium-mediated reactions are treated: (1) oxidative cyclization reactions promoted by palladium (II) species; (2) transmetallation reactions with organoboranes, organostannanes, and organozinc reagents; (3) inter- and intramolecular Heck reactions; (4) reactions with &pgr;-allylpalladium as the intermediate; and (5) reactions using C-N bond formation as the key step for the synthesis.
