The alkaloids were of great importance to mankind for centuries, long before they were recognized . as a chemical class. The influence they have had on literature is hinted at by some of the quotations I have used as chapter headings. Their influence on folklore and on medicine has been even greater. The scientific study of alkaloids may be said to have begun with the isolation of morphine by Sertiirner in 1804. Since that time they have remained of great interest to chemists, and now in any month there appear dozens of publications dealing with the isolation of new alkaloids or the determination of the structures of previously known ones. The area of alkaloid biochemistry, in comparison, has received little attention and today is much less developed. There is a certain amount of personal arbitrariness in defining "bio chemistry", as there is in defining "alkaloid", and this arbitrariness is doubtless compounded by the combination. Nevertheless, it seems to me that in any consideration of the biochemistry of a group of compounds three aspects are always worthy of attention-pathways of biosynthesis, function or activity, and pathways of degradation. For the alkaloids, treatment of these three aspects is necessarily lopsided. Much has been learned about routes of biosynthesis, but information on the other aspects is very scanty. It would be possible to enter into some speculation regarding the biosynthesis of all the more than 4,000 known alkaloids.

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 is designed for the use of the advanced student and professional worker interested in the international scientific community, particularly those in the fields of agronomy, agricultural sciences, botany, biological sciences, natural products chemistry, pharmaceutical chemistry and bio chemistry. The purpose is to inform the reader about significant advances in the biology and metabolism of alkaloids in plants. Since alkaloids are generally referred to as "secondary metabolites," the reactions discussed are not, for the most part, involved with the main metabolic pathways. The reactions that we are interested in are pathways that have been developed for the formation of these secondary metabolites, using as their starting mole cules one of the compounds produced via a main or primary metabolic path way. The primary metabolic pathways are common to all plants, indeed to most living organisms, whereas the highly specialized branches leading to alkaloid formation are found in only about 10 to 20 % of the known plants. The reason for these diversities in plant metabolism is not clear; however, it seems likely that the formation of highly individualized and specialized pathways resulted as a response to the pressure of natural selection. Nevertheless, the genetic peculiarity that controls alkaloid production has provided many extremely interesting problems for scientists and consti tutes convincing evidence of nature's superior ability in biochemistry.

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.

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.
