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.

Volume 8 of this series presents four timely reviews on alkaloids: Chapter 1 is a magnificent and monumental review of curare, "a group of dart and/or arrow poisons varying in composition and featuring muscle relaxation as their basic pharmacological action." The fascinating history of curare is recounted, beginning with early encounters by the Spanish Conquistadores through its use as arrow poisons by the forest tribes in hunting and warfare, its chemistry, ethnography, botany and pharmacology. A terminal section of this chapter treats the development of modern muscle relaxants. This chapter thus traces how curare-initially only a crude plant extract-has given rise to the widely used and very important neuromuscular blocking agents of today. The precise role of plant secondary metabolites and their interactions with insect herbivores have been focal points for research by chemists, botanists and entomologists for many years. Alkaloids and their glycosides are frequently involved as feeding deterrents. Chapter 2 treats the relationships between the chemistry of alkaloids in host plants and the effects that these compounds may have on insect herbivores. Interestingly, an alkaloid produced by a plant may manifest different effects on different insects.

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
