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.

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.

Not since the late 1970s has a single work presented the biology of this heterogenous group of secondary alkaloids in such depth. Alkaloids, a unique treatise featuring leaders in the field, presents both the historical use of alkaloids and the latest discoveries in the biochemistry of alkaloid production in plants alkaloid ecology, including marine invertebrates, animal and plant parasites, and alkaloids as antimicrobial and current medicinal use . Highlights include chapters on the chemical ecology of alkaloids in host-predator interactions, and on the compartmentation of alkaloids synthesis, transport, and storage. Extensive cross-referencing in tabular format makes this volume an excellent reference.

This book covers all aspects of toxicology, including toxic diseases of large animals, small animals, and exotic pets. It provides key information on how poisons affect the body, how the body responds to a foreign substance, how poisonings are diagnosed, and how poisonings are treated. Coverage includes every organ system of every species of animal with details on each body system's susceptibility to poison. Poisons affect animals differently depending on species, breed, age, gender, health status, and reproductive status. This resource addresses these differences, allowing the veterinarian to determine the class of toxicant, the mechanism of action, and the proper course of treatment. If confronted with an unknown poison, the information in this book will assist the veterinarian in formulating a list of potential poisons based on the clinical signs that the animal is exhibiting, and in choosing the appropriate tests to narrow the list to one or a few possible poisons. Most comprehensive toxicology book available Written in a user-friendly style that makes it easy to master the content Covers poisonings in both large and small domestic animals The Principles of Toxicology section provides comprehensive coverage of concepts & terminology, toxicokinetics, treatments, and regulatory information The Manifestations of Toxicoses section is devoted to differentiating between poisons based on lesions and clinical signs The Classes of Toxicants section offers detailed information on each poison, including sources, risk factors, pathophysiology, clinical signs and lesions, diagnostic testing, and treatment The author is board-certified in toxicology, and the contributors are all toxicologists and educators, ensuring authoritative, up-to-date clinical information
