Abstract

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 second contribution offers a comprehensive view of the chemical wealth and the taxonomic problems currently impeding chemical and biological investigations of the genus Laurencia. It addresses the botanical description and the growth and population dynamics of the genus, as well as its chemical diversity and ecological relations; the secondary metabolites as well as their sources of isolation; and finally the biological activity.

Abstract

The volumes of this classic series, now referred to simply as "Zechmeister" after its founder, Laszlo Zechmeister, have appeared under the Springer Imprint ever since the series' inauguration in 1938. The series has featured contributions by seven Nobel laureates: D.H.R. Barton, D. Crowfoot Hodgkin, L. Pauling, K. Alder, O. Diels, P. Karrer, and H. von Euler-Chelpin. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in the field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists, and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.

Abstract

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, proteins, or nucleic acids. The final sections discuss the methodology used and the fundamental processes encountered by the biomolecules described, including diagenesis, catagenesis, and metagenesis. The second contribution covers the distribution of phthalides in nature and the findings in the structural diversity, chemical reactivity, biotransformations, syntheses, and bioactivity of natural and semisynthetic phthalides.

Abstract

The first contribution presents coumarins, the largest group of 1-benzopyran derivatives found in plants. Coumarin chemistry remains one of the major interest areas of phytochemists, especially because of their structural diversity and medicinal properties, along with the wide-ranging bioactivities of these compounds, inclusive of analgesic, anticoagulant anti-HIV, anti-inflammatory, antimicrobial, antineoplastic, antioxidant, and immunomodulatory effects. The second contribution presents a comprehensive survey of the many aspects of PAD biochemistry and physiology. The third contribution gives a comprehensive overview of secondary metabolites from higher fungi, with more than 700 references highlighting the isolation, structure elucidation, biological activities, chemical synthesis, and biosynthesis of pigments, nitrogen-containing compounds, and terpenoids from mushrooms. .

Abstract

The first contribution reviews the occurrence of xanthine alkaloids in the plant kingdom and the elucidation of the caffeine biosynthesis pathway, providing details of the N-methyltransferases, belonging to the motif B' methyltransferase family which catalyze three steps in the four step pathway leading from xanthosine to caffeine. The second contribution in this book provides a background on the molecule and related compounds and update knowledge on the most recent advances in Iboga alkaloids. The third contribution presents a comprehensive analysis of frequently occurring errors with respect to 13C NMR spectroscopic data and proposes a straightforward protocol to eliminate a high percentage of the most obvious errors.

Abstract

"Studies of comparative classroom practice in the teaching of secondary English are limited, especially when it comes to exploration of the day-to-day practice of English teachers in the secondary classroom. This book presents a case study analysis of secondary classroom practice in three countries: Canada, England and Scotland. Each country has had different degrees of state involvement within the secondary English curriculum over the last twenty years. England has had the highest degree of state involvement in that it has had several statutory national curricula and a variety of assessment regimes. Scotland has had a non- statutory curriculum and no national tests and Canada has had no national curriculum at all, with education being determined at province level, and each province varying its policies. The research adopts a case study approach involving both classroom observation and interviews with teachers. Through this, the authors explore the impact of state involvement on the reality of what happens in secondary English classrooms. The book invites readers to consider the applicability of the findings to their own contexts, to examine their own practice in the light of this and to consider the nature of the relationships between policy, personal belief and practice in the teaching of English."--Bloomsbury Publishing.

Abstract

The first review describes examples of very promising compounds discovered from plants acquired from Africa, Southeast Asia, the Americas, and the Caribbean region with potential anticancer activity. These include plant secondary metabolites of the diphyllin lignan, penta[b]benzofuran, triterpenoid, and tropane alkaloid types. The second review presents 40 more erythrinan alkaloids, which were either new or were missed out in the last major reviews, bringing to a total of 154 known erythrinan alkaloids known to date. The reported pharmacological activities of the new and known alkaloids showed a greater bias towards central nervous system and related activities. Other prominent activities reported were antifeedant or insecticidal, cytotoxicity/anti­tumor/anti­cancer/estrogenic, antiprotozoal, antiinflammatory, antioxidant, antifungal and antiviral activities.
