Book Description :

Alkaloids are a large group of structurally complex natural products displaying a wide range of biological activities. The purpose of Alkaloids: A Treasury of Poisons and Medicines is to classify, for the first time, the alkaloids isolated from the natural sources until now. The book classifies all of the alkaloids by their biosynthetic origins. Of interest to the organic chemistry and medicinal chemistry communities involved in drug discovery and development, this book describes many alkaloids isolated from the medicinal plants, including those used in Japanese Kampo medicine.

Book Description :

Alkaloids, represent a group of interesting and complex chemical compounds, produced by the secondary metabolism of living organisms in different biotopes. They are relatively common chemicals in all kingdoms of living organisms in all environments. Two hundred years of scientific research has still not fully explained the connections between alkaloids and life. Alkaloids-Chemistry, Biological Significance, Applications and Ecological Role provides knowledge on structural typology, biosynthesis and metabolism in relation to recent research work on alkaloids. Considering an organic chemistry approach to alkaloids using biological and ecological explanation. Within the book several questions that persist in this field of research are approached as are some unresearched areas. The book provides beneficial text for an academic and professional audience and serves as a source of knowledge for anyone who is interested in the fascinating subject of alkaloids. Each chapter features an abstract. Appendices are included, as are a listing of alkaloids, plants containing alkaloids and some basic protocols of alkaloid analysis. * Presents the ecological role of alkaloids in nature and ecosystems * Interdisciplinary and reader friendly approach * Up-to-date knowledge

Book Description :

A Course in Organic Chemistry Advanced Section, Volume 27: Indole Alkaloids: An Introduction to the Enamine Chemistry of Natural Products describes the chemistry of selected alkaloids that contain indolic or closely related nuclei. Some five hundred of these compounds have been obtained from about three hundred plants mostly of the family Apocynaceae. This book is composed of 12 chapters that specifically cover the chemistry of the complex indoles. The introductory chapters deal with the origin, isolation, characterization, basic chemistry, and simple derivatives of indole alkaloids. The remaining chapters examine the biogenesis, basic chemistry, stereochemistry, and structure of selected complex alkaloids of various origins. These chapters include tetrahydro-?-carboline, strychnos, iboga, picralima, and eburnamine alkaloids, cinchonamine, quinamine, and ajmaline-sarpagine bases. This text is of great value to organic chemists and researchers.

Book Description :

Plants containing pyrrolizidine alkaloids are so numerous and widespread that they can be expected to be present in most environments. About 200 pyrrolizidine alkaloids have been isolated and identified from different plants. Interest in these alkaloids has increased in recent years due to their causative effects in the heavy loss of livestock in many countries. Naturally Occurring Pyrrolizidine Alkaloids discusses the plant sources and properties of pyrrolizidine alkaloids; extraction, fractionation and identification; various methods of spectrometry of pyrrolizidine alkaloids; quantitative determination; and the toxicity, carcinogenicity, pharmacology, and other biological activities of pyrrolizidine alkaloids. Researchers in veterinary and human medicine will find this book to be a fascinating and useful reference tool.

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.

Book Description :

Volume 10 of this series presents four timely reviews. Chapter 1 provides a fascinating account of the history of alkaloid discovery in Australia beginning with the isolation of the first alkaloid from an Australian plant, the Tasmanian sassafras (Atherosperma moschatum), by Zeyer in 1861. Also included is a comprehensive survey of alkaloid-bearing plants, and a section dealing with detection, estimation, extraction, and work-up procedures for alkaloids. Chapter 2 provides a comprehensive update to the chapter on "Pyridine and Piperidine Alkaloids" which appeared in volume 3 of this series. The focus of this chapter is on new alkaloids isolated, biosynthesis, and biological properties. Chapter 3 looks at "3-Alkylpiperidine Alkaloids Isolated from Marine Sponges in the Order Haplosclerida". Studies over the past thirty years have shown that sponges are a rich source of alkaloids. Many of these sponge alkaloids are related to each other by the presence of a 3-alkylpiperidine moiety in their structures and it happens that the sponges that have been reported to contain 3-alkylpiperidine alkaloids are all in the order Haplosclerida. Chapter 4 reviews &bgr;-carboline and isoquinoline alkaloids which are pharmacologically some of the most significant marine natural products. This chapter treats the isolation, structure elucidation, synthesis, biosynthesis, and pharmacological activity of these alkaloids.
