Taschenbuch. Zustand: 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.…

Zustand: Hervorragend. Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | This book presents recent reports of total syntheses involving a photocatalytic reaction as a key step in the methodology. Modern photocatalysis has proven its generality for the development and functionalization of native functionalities. To date, the field has found broad applications in diverse research areas, including the total synthesis of natural products. Among the selected examples presented in this book, it highlights how the photocatalytic process proceeds in a highly chemo-, regio-, and stereoselective manner, thereby allowing the rapid access to structurally complex architectures under light-driven conditions.…

Zustand: Hervorragend. Zustand: Hervorragend | Seiten: 348 | Sprache: Englisch | Produktart: Bücher | 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.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This volume consists of four chapters that cover a structurally diverse range of naturally occurring compounds. Chapter 1 delves into the chemistry of pyrogallols and their oxidized products, the hydroxy-o-quinones, including their role in cycloaddition reactions in the chemical synthesis of several fungal metabolites. Chapter 2 provides an in-depth description of the constituents of agarwood essential oil and smoke samples that are used in the perfumery industry, with an emphasis on the sesquiterpenoid and chromones constituents so far known. Chapter 3 discusses the defensive chemical ecology of two North American newt species that both produce tetrodotoxin, a well-known neurotoxin that causes paralysis and death in metazoans by disrupting electrical signals in the nerves and muscles. Chapter 4 discusses the limonoids and triterpenoids from the genus Walsura of the plant family Meliaceae, of whicha number ofspecies are utilized in several southeastern Asian countries in systems of folk medicine. …

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - 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.…
