The emerging diversity of active compounds is covered in detail, including flavonoids, cannabinoids and oleanolic acid, while experts in the field explain the chemistry, mode of action and clinical aspects of novel neuroprotective natural products. In each case, the benefits of treatments using natural products are addressed from the perspective of modern as well as traditional medicine. With its multidisciplinary viewpoint, this is the ideal companion for medicinal and natural products chemists as well as neuroscientists, biochemists, pharmacologists, neurobiologists, and phytotherapists.

Natural compounds, which have evolved their function over millions of years, are often more efficient than man-made compounds if a specific biological activity is needed, e.g. as an enzyme inhibitor or as a toxin to kill a cancer cell. This book comprising of sixteen technical chapters, highlights the chemical and biological aspects of potential natural products with an intention of unravelling their pharmaceutical applicability in modern drug discovery processes. Key features: Covers the synthesis, semi-synthesis and also biosynthesis of potentially bioactive natural products Features chemical and biological advances in naturally occurring organic compounds describing their chemical transformations, mode of actions, and structure-activity relationships 40 expert scientists from around the world report their latest findings and outline future opportunities for the development of novel and highly potent drugs based on natural products operating at the interface of chemistry and biology Forward-looking: Addresses opportunities and cutting-edge developments rather than well-documented basic knowledge, pinpoints current trends and future directions in this rapidly-evolving field Application-oriented: Throughout the book, the focus is on actual and potential applications in pharmacology and biotechnology This book is an essential resource for natural products chemists, medicinal chemists, biotechnologists, biochemists, pharmacologists, as well as the pharmaceutical and biotechnological industries.

Intense research has been started all around the world in the past few decades to exploit different agents from natural products as eco-friendly alternative to synthetic and toxic chemicals. Natural products and their derivatives have received increasing attention for their use in many everyday applications ranging from food, medicine, textiles, and healthcare.This new book presents significant research advances about the use of natural products, mainly plant colorants, bioactive compounds and other plant extracts in the textile coloration, food, bioremediation and environmental applications. There are total eight chapters contributed by leading researchers covering the topics such as potential resurgence of natural dyes in applied fields, natural colorants from indigoid plants, phytochemistry of dye yielding plants, irradiation as novel pretreatment methods, dyeing studies with henna plant, phytoremediation of arsenic, and synthesis of curcumin complexes for medicinal and other industrial uses.

Based on the award winning Wiley Encyclopedia of Chemical Biology, this book provides a general overview of the unique features of the small molecules referred to as «natural products», explores how this traditionally organic chemistry-based field was transformed by insights from genetics and biochemistry, and highlights some promising future directions. The book begins by introducing natural products from different origins, moves on to presenting and discussing biosynthesis of various classes of natural products, and then looks at natural products as models and the possibilities of using them in medicine.

The inspiration provided by biologically active natural products to conceive of hybrids, congeners, analogs and unnatural variants is discussed by experts in the field in 16 highly informative chapters. Using well-documented studies over the past decade, this timely monograph demonstrates the current importance and future potential of natural products as starting points for the development of new drugs with improved properties over their progenitors. The examples are chosen so as to represent a wide range of natural products with therapeutic relevance among others, as anticancer agents, antimicrobials, antifungals, antisense nucleosides, antidiabetics, and analgesics. From the content: * Part I: Natural Products as Sources of Potential Drugs and Systematic Compound Collections * Part II: From Marketed Drugs to Designed Analogs and Clinical Candidates * Part III: Natural Products as an Incentive for Enabling Technologies * Part IV: Natural Products as Pharmacological Tools * Part V: Nature: The Provider, the Enticer, and the Healer

Asymmetric Synthesis of Natural Products, 2nd Edition introduces students to this rapidly growing field of organic chemistry. The initial chapters present the foundations of asymmetric synthesis, including the theory and applications of individual asymmetric reactions. This is followed by chapters on each of the major individual classes of natural products; their structures, biosynthesis and interrelationships as well as examples of asymmetric syntheses and the practical value of these compounds. Natural product classes covered include carbohydrates, amino acids, peptides, proteins, nucleosides, nucleotides, nucleic acids, polyketides, isoprenoids, shikamic acid derivatives and alkaloids. For this second edition the text has been thoroughly updated and expanded, and includes new discussions and examples covering atom and redox economies, practical aspects and environmental awareness. Organocatalysis has emerged completely in the last ten years, and has been fully integrated into this new edition.

Current discoveries and research into bioactive natural products Medicinal Chemistry of Bioactive Natural Products provides a much-needed survey of bioactive natural products and their applications in medicinal chemistry. This comprehensive reference features articles by some of the world's leading scientists in the field on discovery, structure elucidation, and elegant synthetic strategies–developed for natural products–with an emphasis on the structure activity relationship of bioactive natural products. The topics have been carefully chosen on the basis of relevance to current research and to importance as clinicially useful agents. Rather than attempting to be a comprehensive encyclopedia of bioactive natural products, Medicinal Chemistry of Bioactive Natural Products guides the reader to the key developments in the field. By providing not only practical detail but a historical perspective on the chemistry and biology of the compounds under consideration, the book serves as a handy resource for researchers in their own work developing pharmaceuticals, and as an inspiring introduction for young scientists to the dynamic field of bioactive natural products research. Enhanced by examples with updated research results, the discussion covers such topics as: * The chemistry and biology of epothilones * Vancomycin and other glycopeptide antibiotic derivates * Antitumor and other related activities of Taxol and its analogs * The antimalarial properties of the traditional Chinese medicine, Quinghaosu (artemisinin) * Huperzine A: A natural drug for the treatment of Alzheimer's disease * The medicinal chemistry of ginkgolides from Ginkgo biloba * Recent progress in Calophyllum coumarins as potent anti-HIV agents * Plant-derived anti-HIV agents and analogs * Chemical synthesis of annonaceous acetogenins and their structurally modified mimics

More and more attention is being paid to natural products chemistry. The number of recently discovered and described natural products is constantly increasing, leading to an abundance of detailed information in diverse specialist journals. The Roth Collection of Natural Products Data gives a clear overview of this development. It presents the data of approximately 75 selected natural products of plant origins in a concise and standardized form. The collection contains descriptions of the products with information on the physical and chemical properties, location, toxicology and risk potential. Complete spectroscopic and chromatographic data with clear information on measurement conditions and peaks round off the detailed depictions. With its illustrations of NMR, mass and IR spectra and its structural formulas, the collection is an important and stimulating reference work. Selected and commented references on each natural product facilitate the search for further information. Natural product chemists, pharmacists, biologists and toxicologists in research, industry and academia will soon find this reference work indispensable.
