Download or read book Sesquiterpene Lactones written by Valeria Patricia Sülsen and published by Springer. This book was released on 2018-06-07 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses chemical and biological aspects related to sesquiterpene lactones (STLs). Experts in different fields have been invited to contribute on this class of compound's chemistry, isolation and identification, biological activities (antibacterial, antifungal, antiviral, antitrypanosomal, antileishmanial,antiplasmodial, antiproliferative and antiinflammatory), synthesis, biosynthesis, derivatization and QSAR analysis. Taxonomic and chemotaxonomic aspects related to the Asteraceae family are also contributed. The book begins by describing the chemical characteristics of STLs, their classification in different skeleton types, synthesis, distribution in nature and their most important biological properties. An overview of the group's main representatives, based on their importance for human health, as well as an update of the most recently isolated STLs, follow. The authors also provide an overview of the most common methods described in the literature for the extraction, purification, identification and structure elucidation of STLs, while also highlighting more recently developed methods. Furthermore, experts in the field provide an in-depth discussion of the most commonly employed in vitro and in vivo antiprotozoal assays against the different stages of parasites, as well as STLs' properties as anticancer agents in numerous cancer cell lines and animal models. Lastly, the book presents examples of the in vitro and in vivo activity of STLs and their mechanism of antiprotozoal action, together with an analysis of ultrastructural alterations, observed using TEM techniques. The book is aimed at scientists working on natural products: both those investigating this particular group of compounds and those who wish to further explore its potential as new drugs for medical conditions such as protozoal diseases and cancer.
Download or read book Biochemistry of the Mevalonic Acid Pathway to Terpenoids written by G.H.Neil Towers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: This series of lectures was delivered at the 29th meeting of the Phytochemical Society of North America, held at the University of British Columbia in Vancouver, B. C. , Canada on June 16th-20th, 1989. Topics concerning terpenoids, consisting of isoprene units, are now so numerous that a judicious selection for a relatively limited symposium was difficult. We were able to assemble, however, a potpourri of reviews on topical areas of terpenoid chemistry, biochemistry and biology, by scientists who are making exciting contributions and whose work points the way to significant future research. Because of the importance of terpenoids in the life of plants, and indeed in all living organisms, a periodical review of the mevalonic acid pathway and of the subsequent biochemical events leading to the biosynthesis of isoprenoids needs no justification. Life, as we know it, would not be possible without the ability of living organisms to employ this metabolic sequence which proceeds from condensations of three molecules of acetyl-CoA and terminates with the elaboration of the terpenoid precursors, isopentenyl pyrophosphate and dimethylallyl pyrophosphate. In addition to producing obviously essential compounds that are partially or completely of isoprenoid origin (Fig. 1), such as hormones, photosynthetic pigments, compounds involved in electron transport in respiration and in photosynthesis, oxidative enzymes and membrane components, plants elaborate thousands of novel terpenoids, many of which do not as yet have identifiable physiological, biochemical or even ecological roles, e. g. the cardenolides, ecdysones or saponins.

Download or read book The Poisoned Weed written by Donald G. Crosby and published by Oxford University Press. This book was released on 2004-04-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over-two thirds of the U.S. population is allergic to poison oak, poison ivy, or a related plant. These and many other common plants in our homes, fields, and gardens are irritants that cause misery to many. But surprisingly, there has never been a general guide to help raise awareness of them--and to help avoid them. This new book reviews the history, occurrence, classification, toxicity, and health aspects of all the major allergenic and irritant species.
Download or read book Modern Phytochemical Methods written by Nikolaus H. Fischer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains reviews which are based on a symposium, given th at the 30 meeting of The Phytochemical Society of North America, held at Laval University in Quebec City, Canada on August 11-15, 1990. During the past two decades, there have been major new developments in methods which can be applied toward the isolation, separation and structure determination of complex natural products. Therefore, the topic of this symposium, "Modem Phytochemical Methods", is a very timely one. The organizers of the symposium recognized that it would not be possible to cover in detail all new advances in phytochemical methodology. It was therefore decided to emphasize general reviews on recent developments of major separation techniques such as high performance liquid chromatography as well as supercritical fluid chromato graphy. In addition, advances in commonly used structure determination methods, mainly NMR and MS, are reviewed. Other topics include methodo logies of micro-sampling for isolation and analysis of trichome constituents as well as recent breakthroughs on biosynthetic studies of monoterpenes using "enriched" basal cells of trichomes. The volume concludes with a review of quantitative structure-activity relationship (QSAR) studies of biologically active natural products. In Chapter I, K. Hostettmann and his colleagues give a general review of recent developments in the separation of natural products with major emphasis on preparative separations of biologically active plant constituents. The authors present a comparison of droplet countercurrent chromatography (OCCC) with the highly rapid and more versatile centrifugal partition chromatography (CPC).
