Etat : Sehr gut. Zustand: Sehr gut | Seiten: 304 | Sprache: Englisch | Produktart: Bücher | The first contribution summarizes current trends in research on medicinal plants in Mexico with emphasis on work carried out at the authors' laboratories. The most relevant phytochemical and pharmacological profiles of a selected group of plants used widely for treating major national health problems are described. The second contribution provides a detailed survey of the so far reported literature data on the capacities of selected oxyprenylated phenylpropanoids and polyketides to trigger receptors, enzymes, and other types of cellular factors for which they exhibit a high degree of affinity and therefore evoke specifice responses. And the third contribution discusses aspects of endophytic actinobacterial biology and chemistry, including biosynthesis and total synthesis of secondary metabolites produced in culture. It also presents perspectives fo the future of microbial biodiscovery, with emphasis on the seondary metabolism of endophytic actinobacteria.…

Hardcover. Etat : new. Hardcover. This book, ''Phytochemicals of Pteridophytes: Occurrence, Structures, and Biological Activity'', explores the chemical constituents of pteridophytes (lycophytes and ferns), emphasizing their occurrence, structures, and biological functions. It covers a wide range of phytochemicals, including aromatic compounds (e.g., acylphloroglucinols, flavonoids, lignans, selaginellins) and isoprenoids (e.g., monoterpenoids, norisoprenoids, sesquiterpenoids, diterpenoids, and steroids). The book examines the distribution of these compounds across various pteridophyte genera and species, highlights their structural diversity, and outlines their pharmacological properties. It also compares the phytochemical profiles of pteridophytes with those of algae and bryophytes. This book, ''Phytochemicals of Pteridophytes: Occurrence, Structures, and Biological Activity'', explores the chemical constituents of pteridophytes (lycophytes and ferns), emphasizing their occurrence, structures, and biological functions.

Taschenbuch. Etat : Neu. Druck auf Anfrage Neuware - Printed after ordering - This volume begins with a short history of malaria and follows with a summary of its biology. It then traces the fascinating history of the discovery of quinine for malaria treatment, and then describes quinine's biosynthesis, its mechanism of action, and its clinical use, concluding with a discussion of synthetic antimalarial agents based on quinine's structure. It also covers the discovery of artemisinin and its development as the source of the most effective current antimalarial drug, including summaries of its synthesis and biosynthesis, its mechanism of action, and its clinical use and resistance. A short discussion of other clinically used antimalarial natural products leads to a detailed treatment of additional natural products with significant antiplasmodial activity, classified by compound type. Although the search for new antimalarial natural products from Nature's combinatorial library is challenging, it is very likely to yield new antimalarial drugs. This book thus ends byidentifying ten natural products with development potential as clinical antimalarial agents.…

Hardcover. Etat : new. Hardcover. This book describes a unique class of secondary metabolites, the mono- and dimeric-naphthylisoquinoline alkaloids. They exclusively occur in lianas of the palaeotropical Ancistrocladaceae and Dioncophyllaceae plant families. Their unprecedented structures include stereogenic centers and rotationally hindered, and therefore stereogenic, axes. Extended recent investigations on six Ancistrocladus species from Asia, as reported in this contribution, shed light on their fascinating phytochemical productivity, with over 100 intriguing natural products. This high chemodiversity arises from a similarly unique biosynthesis from acetate-malonate units, following a novel polyketidic pathway to plant-derived isoquinoline alkaloids. Some of the compounds show most promising anti-parasitic activities. Additionally, strategies for the regio- and stereoselective total synthesis of the alkaloids, including the directed construction of the chiral axis, are also presented.
