Book Description
Natural products are increasingly attracting attention from both basic and applied science. Plant secondary metabolites, especially alkaloids, are receiving interest from a wide range of researchers due to their biological activity. They are produced to protect plants from diseases and herbivores. Therefore, they reveal a toxic activity that affects organisms at various levels of biological organization. A growing amount of research is proving their antimicrobial, antifungal, insecticidal, and anticancer activities. That makes them applicable in various fields from medicine, to pharmacology, veterinary, and toxicology, to crop protection. This Special Issue of Toxins, “Biological Activities of Alkaloids: From Toxicology to Pharmacology", collects 15 manuscripts describing the ecological, biological, pharmacological, and toxicological effects as well as structural and analytical aspects of plant alkaloids, their mode of action, and possible application in veterinary, medicine, and plant protection. These studies prove the potential for alkaloid application in various areas of science.

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
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. Classifies and lists alkaloids from natural sources Occurrence and biosynthetic pathways of alkaloids Indicates key uses and bioactivity of alkaloids

Book Description
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.

Book Description
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.
