This volume is devoted to the research area regarding the biological properties of metal alkyl derivatives, offering an authoritative account of this subject by 16 scientists. In 11 chapters, Biological Properties of Metal Alkyl Derivatives highlights, in detail, derivatives of germanium, tin, lead, arsenic, antimony, selenium, tellurium, cobalt (vitamin B12 derivatives) and nickel (coenzyme F430), including the role of (mainly) micro-organisms in their formation. The derivatives of indium, thallium, bismuth, various transition metals and mercury are also covered to some extent, as are those of the non-metals silicon, phosphorus and sulfur, and the haloperoxidase route of the biogenesis of halomethanes by fungi and plants. The properties of these alkyl derivatives, their biosynthesis, including mechanistic aspects, their appearance in waters (rivers, lakes, oceans) and sediments, and their physiological and toxic effects are summarized.

Alkaloids are a major group of natural products derived from a wide variety of organisms and are widely used as medicinal and biological agents. This series is world-renowned as the leading compilation of current reviews of this vast field. Volume 56 presents the Proceedings from the First International Conference on Ibogaines, held in November of 1999 at New York University's School of Medicine. In essence, it presents significant new data on neurobiological, clinical, sociocultural, and policy aspects of ibogaine.Ibogaine is a natural product derived from the bark of the root of the African shrub Tabernathe iboga. It has a history of use as a medicinal and ceremonial agent in West Central Africa, and has been alleged to be effective as a treatment for substance dependence. The study of Ibogaine may shed light on the neurobiology of addiction and lead to the development of new medication for the treatment of addiction. Currently, there is lack of formal approval for the use of ibogaine, and the demand of the addicts themselves has led to a distinctive unofficial network which has provided ibogaine treatment in non-medical settings. If critical safety concerns can be adequately addressed, ibogaine may provide an inexpensive and practical treatment approach, well adapted to environments where resources are severely limited and there is pressing need for clinical services for heroin addicts, such as Eastern Europe.

This series is world-renowned as the leading compilation of current reviews of this vast field. Internationally acclaimed for more than forty years, The Alkaloids: Chemistry and Biology, founded by the late Professor R. H. F. Manske, continues to provide outstanding coverage of the rapidly expanding field of the chemotaxonomy, structure elucidation, synthesis, biosynthesis, and biology of all classes of alkaloids from higher and lower plants, marine organisms, and various terrestrial animals. Each volume provides, through its distinguished authors, up-to-date and detailed coverage of particular classes or sources of alkaloids. This, the 58th volume in the series presents two quite different aspects of alkaloids. The first of the two chapters reviews the substantial progress made on the biotransformations of various classes of alkaloids and examines the enzymes systems involved in this process. Such studies are proving very important in the consideration of how alkaloids can be used in the future as medicinal or biological agents. The second chapter presents a comprehensive review of the known polyamine alkaloids based on their biogenesis and additionally provides overviews of their detailed structural analysis, their synthesis, biosynthesis and biology. * The 58th volume in this series of essential reference works * Written by leading experts in the field* An essential research tool for anyone working with alkaloids in chemistry or biology

It is refreshing to find a book treating alkaloid analysis with all the latest techniques such as inverse-detected two dimensional NMR, GC/MS, and HPLC associated techniques. There have been many developments in the field of alkaloid analysis since the 1950s, not the least of which are the various powerful spectroscopic methods, which dominate this volume. Included also are the various aspects of tobacco alkaloids and analysis in various situations. The complexities of sampling and analysis in tobacco smoke is explained. Analysis of alkaloids produced by tobacco root cell cultures is included, while genetic and chemical analysis is described for Papaver, a plant of considerable medicinal significance.

Volume 11 of this series presents five timely reviews on current research on alkaloids. Chapter 1 by Paul L. Schiff, Jr. is a monumental survey of research that has been carried out over the past decade on the Thalictrum alkaloids. Forty-six new alkaloids are described from fifteen species of the genus Thalictrum, as well as 116 alkaloids of known structure from thirty-six species and subspecies of the genus. The chapter includes discussions of isolation and structure elucidation, analysis, biosynthesis, cell culture, and pharmacology. Also featured are inclusive compilations of botanical sources, alkaloids by alkaloid types, and calculated molecular weights of the Thalictrum alkaloids.Chapter 2 by Giovanni Appendino provides a fascinating treatment of Taxine, a collective name referring to a mixture of diterpenoid alkaloids from the yew tree (genus: Taxus). Taxine is responsible for the toxic properties of the yew tree that has been documented in historical and fictional literature, from Julius Caesar to Shakespeare, and from Agatha Christie to T.S. Eliot. The chapter treats the history, isolation techniques, structure elucidation, chemistry, and pharmacology of Taxine.Chapter 3 by Mary D. Menachery surveys the alkaloids of South American Menispermaceae (moonseed family). Many different structural types are included in this family. The alkaloid-bearing plants are woody-vines, shrubs, or small trees. Several of these species possess potent curare activity. The chemistry as well as pharmacology of these alkaloids is summarized.Chapter 4 by Russell J. Molyneux, Robert J. Nash, and Naoki Asano treats the chemistry and biological activity of the calystegines and related nortropane alkaloids. These polyhydroxylated bicyclic alkaloids represent another class of compounds that inhibit glycosidases, producing profound effects in biological systems by disrupting the essential cellular function of glycoprotein processing.Chapter 5, a related chapter by Robert J. Nash, Naoki Asano, and Alison A. Watson, reviews polyhydroxylated alkaloids that inhibit glycosidases. Topics covered include distribution, ecological significance and toxicity, isolation, synthesis, and biosynthesis.

Acronycine, a potent antitumor agent, was discovered in the bark of the small Australian Rutaceous tree, Acronychia baueri Schott. This new work presents a comprehensive survey of the isolation, structure determination, methods of synthesis, and the biological properties of acronycine, as well as an account of natural and synthetic analogues of acronycine, and their biological properties. Solanum alkaloids were reviewed in 1990 and this book surveys the new developments (isolation procedures, structural elucidation methods) and critically updates earlier reviews. In addition it presents the interesting chemistry and synthesis of cyclopeptide alkaloids. These cyclopeptide alkaloids have been isolated from ascidians, sea hares, and cyanobacteria. Also included are reviews of the use of the functionalized lactam, pyroglutamic acid, as a chiral template for the synthesis of alkaloids. The second review examines the on-line coupling of capillary electrophoresis (CE) and mass spectrometry (MS) for the analysis of alkaloid mixtures. Finally a review of oxygenated analogs of the alkaloid Marcfortine for their potent antiparasitic activity is included at the end of this work. Each chapter in this volume has been reviewed by at least one expert in the field. Indexes for both subjects and organisms are provided.

Volume 13 of this series presents five timely reviews of research on alkaloids such as new developments in the chemistry and biology of alkaloids from amphibian skins. It provides a synopsis and tabulation of the hundreds of alkaloids that have been detected, with an emphasis on occurrence, structure, dietary origins, and biological activity. Alkaloids containing the 1, 2, 3, 3a, 8, 8a - hexahydropyrrolo [2,3b] indole ring system and the cyclotryptamines are discussed. An exhaustive list of available structures is provided. The chemical and biological structures have been evaluated critically so as to identify existing errors and expose irregularities in appearance or biological function. In addition, attention is drawn to the possible implications of the accumulated knowledge related to the synthesis, occurrence, and biochemistry of this class of alkaloids. Recent work on alkaloids containing the comparatively non – basic pyrrole ring system is summarized. One of the chapters covers isolation, structure elucidation, biological activity, and selected chemical syntheses of certain pyrrole alkaloids. Recent developments in the chemistry of diterpenoid and norditerpenoid alkaloids occurring in Aconitum, Delphinium and Consolida genera of the Ranunculaceae family used in Chinese and Indian medicine are surveyed and the book ends with a focus on transition metal – catalyzed carbonylations as efficient and novel approaches to the construction of piperidine, izidine and quinazoline alkaloids, which occur in great numbers in nature.

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.
