Biological Activities of Alkaloids


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.

Alkaloids


Book Description

"Alkaloids" is intended for by chemistry, biochemistry, pharmacy, and other medical students, biologists, chemists, biochemists, and other professionals involved in the field of alkaloids. All chapters in this book are written by professionals in the areas of alkaloid chemistry, biology, pharmacy, and other interesting applications. The chapters cover interesting and less obvious information about different groups of alkaloids.




Alkaloids


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




Alkaloids: Chemical and Biological Perspectives


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.

Alkaloids


Book Description

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.
