Chemical Constituents of Bryophytes: Bio- And Chemical Diversity, Biological Activity, and Chemosystematics
ISBN: 9783709110836 / Angielski / Twarda / 2012 / 796 str. Termin realizacji zamówienia: ok. 22 dni roboczych. For some 50 years, Professor Asakawa and his group have focused their research on the chemical constituents of bryophytes and have found that these plants contain large numbers of secondary metabolites, such as terpenoids, acetogenins, and aromatic compounds representative of many new skeletons, which exhibit interesting biological activities. Individual terpenoids, when found as constituents of both a bryophyte and a higher plant, tend to occur in different enantiomeric forms. Professor Asakawa has covered the literature on bryophytes in two earlier volumes of Progress in the Chemistry...

Fortschritte Der Chemie Organischer Naturstoffe / Progress in the Chemistry of Organic Natural Products, Vol. 93
ISBN: 9783709111079 / Angielski / Miękka / 2012 / 264 str. Termin realizacji zamówienia: ok. 22 dni roboczych. Lignans, by convention, are a group of natural products that are formed by linking two phenylpropanoid units (C C units) by oxidative coupling. Most importantly, in 6 3 a lignan, two (C C units) are bound through the central carbon of their side chains, 6 3 0 i. e. the 8 and 8 positions (1, 2). The occurrence of C C -dimers, linked at sites other 6 3 0 than the 8-8 positions, is also known and these compounds have been termed neolignans (3, 4). As these two groups of compounds have close structural as well as biosynthetic relationships, they are often associated together and incorporated...

Toxic Plants: Proceedings of the 18th Annual Meeting of the Society for Economic Botany, Symposium on Toxic Plants, June 11-15, 1977
ISBN: 9780231046862 / Angielski / Twarda / 1979 / 195 str. Termin realizacji zamówienia: ok. 16-18 dni roboczych. The dependency of the human race on plants as renewable sources of many foodstuffs, drugs, textiles, fuel, and building materials in generally acknowledged. However, the harmful effects produced by certain plant constituents, which result in an increasing incidence of poisoning cases in the United States each year, are not so widely appreciated. This book is not intended to be a comprehensive treatise on all substances from plants that are lethal or otherwise injurious to humans or livestock. Instead, owing to tremendous recent advances in the understanding of the chemical nature of their...

ISBN: 9783709111031 / Angielski / Miękka / 2012 / 175 str. Termin realizacji zamówienia: ok. 22 dni roboczych. Resin glycosides are part of a very extensive family of secondary metabolites known as glycolipids or lipo-oligosaccharides and are constituents of complex resins (glycoresins) (1) unique to the morning glory family, Convolvulaceae (2). These active principles are responsible for the drastic purgative action of all the important Convolvulaceous species used in traditional medicine throughout the world since ancient times. Several commercial purgative crude drugs can be prepared from the roots of different species of Mexican morning glories. Their incorporation as therapeutic agents in Europe...

Progress in the Chemistry of Organic Natural Products 104
ISBN: 9783319456164 / Angielski / Twarda / 2017 / 246 str. Termin realizacji zamówienia: ok. 22 dni roboczych. The first contribution describes apolar and polar molecular fossils and, in particular biomarkers, along the lines usually followed in organic chemistry textbooks, and points to their bioprecursors when available. Thus, the apolar compounds are divided in linear and branched alkanes followed by alicyclic compounds and aromatic and heterocyclic molecules, and, in particular, the geoporphyrins. The polar molecular fossils contain as functional groups or constituent units ethers, alcohols, phenols, carbonyl groups, flavonoids, quinones, and acids, or are polymers like kerogen, amber, melanin,...

This volume describes several highly diverse subjects: Chapter 1 explores marine biodiscovery of the North-eastern Atlantic off the coast of Ireland as a model for best practice in research. The second chapter investigates Brazilian Chemical Ecology and examples of insect-plant communication studies that are mediated by natural products demonstrate the beautiful interconnectedness of species in a biome. Our third chapter comprises the advances in the science of the sesquiterpene quinone, perezone, which in 1852 was the first natural product isolated in crystalline form in the New World. The...

Naturally Occurring Organohalogen Compounds
ISBN: 9783031266287 / Angielski / Twarda / 2023 Termin realizacji zamówienia: ok. 22 dni roboczych. The present volume is the third in a trilogy that documents naturally occurring organohalogen compounds, bringing the total number — from fewer than 25 in 1968 — to approximately 8,000 compounds to date. Nearly all of these natural products contain chlorine or bromine, with a few containing iodine and, fewer still, fluorine. Produced by ubiquitous marine (algae, sponges, corals, bryozoa, nudibranchs, fungi, bacteria) and terrestrial organisms (plants, fungi, bacteria, insects, higher animals) and universal abiotic processes (volcanos, forest fires, geothermal events), organohalogens...

Progress in the Chemistry of Organic Natural Products 102
ISBN: 9783319331706 / Angielski / Twarda / 2016 / 252 str. Termin realizacji zamówienia: ok. 22 dni roboczych. The first contribution reviews the phytochemical, chemical, and biological literature on members of the ingenane class of diterpenoids from their first isolation in 1968 through 2015, highlighting unresolved issues both common to phorboids and specific to ingenol derivatives. The biogenesis of ingenol is discussed in the light of the Jakupovic proposal of a dissection between the formation of the macrocyclic Euphorbia diterpenoids and the phorboids, and the clinical development of ingenol mebutate is chronicled in the light of its reverse-pharmacology focus. The first contribution reviews the phytochemical, chemical, and biological literature on members of the ingenane class of diterpenoids from their f... |
