Download or read book Diterpenes of Flowering Plants written by Fred Seaman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 643 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 1200 diterpenes have been identified from approximately 550 Compo sitae taxa (Figure 1 [pp. 219-384], Tables 1-3 [pp. 7-218]). The annual output of such reports rose sharply during the past several years, a trend that was also reflected by other major lipophilic constituents of the Compositae: acetylenes (63, 465), sesquiterpene lactones (266, 458), and benzofurans and chromenes (429). Unlike these other natural products, no review of the diterpene chemistry of the Compositae has been published. Given the bulk of data currently on hand, a review of this topic is clearly overdue. Several major goals influenced the preparation of this review. The first was to provide a useful reference to guide terpenoid chemists to the literature of known compounds. The published reports for 1200 structures provide a sizable body of spectroscopic data applicable to the investigation of new compounds. The study of diterpenes has been hampered by the absence of an all-inclusive nomenclature and classification system for the various skeletal types. Conse quently, a second goal was to organize structural data into a classification scheme designed to group compounds by biogenetic homology, and to standardize such features as diterpene nomenclature and numbering. Pursuant to this goal, the published names (Table 1) and numbering systems (Table 2) for all compounds are included.

Book excerpt: This reference work provides a wealth of information regarding medicinal plants and phytochemicals. It is addressed both to researchers and teachers. The handbook describes phytochemicals, which, by the strictest definition, are chemicals that are produced by plants. During the last decades, more and more groups became actively involved in exploring plants for useful metabolites that lead to the identification of several useful curative agents and many promising molecules to fight and/or prevent diseases, including carcinogenesis and stroke. But when we talk about phytochemicals, there are also medicinal plants where not a single molecule is responsible for the observed properties. This reference work therefore reviews and compiles the information on both these aspects. The volumes contain contributions on phytochemicals and herbal extracts. A large number of natural products obtained from plants and microorganisms is used in cosmetic, drug, flavor and fragrance industries. For this compilation, a range of the most important medicinal herbs and phytochemicals were selected and are described by the recognized authors in the field. The present reference work encompasses the information about well established phytochemicals, biology and biotechnology of medicinal plants or their products, their biosynthesis, novel production strategies, demand and uses, metabolism and bioavailability. There is a surge of information published in recent years on herbal medicine and their pharmacologic effects with single books available on varied subjects. However, all this information is widespread and difficult to overview. Researchers who wish to keep a pace with the rapidly developing field of natural products can now consult this newly compiled handbook to find all information about bioactive molecules and medicinal plants thoroughly compiled in one place!

Book excerpt: This book is the second of two volumes that deal with discovery of chemical pathways of biosynthesis of natural products (secondary metabolites). The first volume covered the use of isotopes in biosynthetic research and the formation of enzyme cofactors and reduced polyketides. This second volume describes biosynthesis of aromatic (unreduced) polyketides, enzymes responsible for cyclization of terpenoids (isoprenoids), and biochemical generation of selected classes of alkaloids (prenylated tryptophan, tropane, pyrrolizidine). Knowledge of the pathways and the techniques to elucidate them opens the door to combinatorial biosynthesis as well as to the production of targeted pharmaceutical agents utilizing a combination of chemistry, molecular biology and protein biochemistry.
Download or read book Terpenes and Terpenoids written by Shagufta Perveen and published by BoD – Books on Demand. This book was released on 2018-12-19 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Terpenes belong to the diverse class of chemical constituents isolated from materials found in nature (plants, fungi, insects, marine organisms, plant pathogens, animals and endophytes). These metabolites have simple to complex structures derived from Isopentyl diphosphate (IPP), dimethyl allyl diphosphate (DMAPP), mevalonate and deoxyxylulose biosynthetic pathways. Terpenes play a very important role in human health and have significant biological activities (anticancer, antimicrobial, anti-inflammatory, antioxidant, antiallergic, skin permeation enhancer, anti-diabetic, immunomodulatory, anti-insecticidal). This book gives an overview and highlights recent research in the phytochemical and biological understanding of terpenes and terpenoid and explains the most essential functions of these kinds of secondary metabolites isolated from natural sources.

Download or read book Plant derived Natural Products written by Anne E. Osbourn and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants produce a huge array of natural products (secondary metabolites). These compounds have important ecological functions, providing protection against attack by herbivores and microbes and serving as attractants for pollinators and seed-dispersing agents. They may also contribute to competition and invasiveness by suppressing the growth of neighboring plant species (a phenomenon known as allelopathy). Humans exploit natural products as sources of drugs, flavoring agents, fragrances and for a wide range of other applications. Rapid progress has been made in recent years in understanding natural product synthesis, regulation and function and the evolution of metabolic diversity. It is timely to bring this information together with contemporary advances in chemistry, plant biology, ecology, agronomy and human health to provide a comprehensive guide to plant-derived natural products. Plant-derived natural products: synthesis, function and application provides an informative and accessible overview of the different facets of the field, ranging from an introduction to the different classes of natural products through developments in natural product chemistry and biology to ecological interactions and the significance of plant-derived natural products for humans. In the final section of the book a series of chapters on new trends covers metabolic engineering, genome-wide approaches, the metabolic consequences of genetic modification, developments in traditional medicines and nutraceuticals, natural products as leads for drug discovery and novel non-food crops.

Download or read book Diterpenoids written by Brandon Jones and published by Nova Science Publishers. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diterpenoids are chemical compounds containing 20 carbon atoms and belong to the terpenoid class. They derive from geranylgeraniol, a C20 precursor, have a C20H32 basic structure, and are composed of four isoprene units. These features make diterpenoids different from simple terpenes, which possess only 10 carbon atoms. A diterpenoid molecule may also include alcohol, phenol, aldehyde, cheton, or acidic functional groups. These compounds are highly lipophilic, odorless, and may possess strong flavours. They are found mainly in fungi and in resins of higher-order plants, as typical products of plant metabolism. This book examines the types, functions and provides new research on diterpenoids.
