Methods For Preclinical Evaluation Of Bioactive Natural Products

Natural products have dominated our lives since ancient times. Today, they are an inexhaustible source of new medications for disease treatment. The practice of evaluating bioactive compounds extracted from natural sources has also advanced significantly, prompting a need to understand current methods to identify and evaluate them. This book covers basic scientific aspects of preclinical research on natural products for specific conditions and diseases. These include aging, gynecological disorders, inflammatory disorders, renal disorders and cardiovascular disorders. Each of the 10 book chapters give a structured overview on preclinical methods on the etiology of diseases, natural products as the materials for the bioassays, extract types, concentration of the extracts/compounds for in vitro and in vivo assays, preparation of the test materials, application of the test materials, step-by-step methods and related calculations. The book is intended as a quick reference for natural product researchers, pharmacists and postgraduate students in pharmacognosy. Medical doctors working in preclinical research on natural products will also benefit from the information provided.

Bioactive natural products are proving to be a rich source of novel therapeutics to both protect against and combat diseases, as well as serve as lead compounds in crop protection. Following the successful format of the first edition, this volume brings together collective research from many new contributors and emphasizes the rationale behind the

Bioassay Methods in Natural Product Research and Drug Development contains the proceedings from the Phytochemical Society of Europe's very successful symposium on this topic, held August 24-27, 1997 in Uppsala, Sweden. In this volume, leading academic and industrial scientists discuss novel methods for assaying natural products to find new structure-activity relationships. Of key importance in this process is the availability and reliability of specific bioassay methods, but chapters also discuss chemical and biological diversity and how to dereplicate natural product extracts to increase efficiency in lead discovery. Anti-tumor, HIV-inhibitory, antiprotozoal, anti-infective and immunomodulatory natural products are discussed. Various industrial projects are presented for the first time. This volume bridges the gap between academic and industrial research and scientists, and should be required reading in drug companies and faculties of pharmacy, as well as serving scientists in pharmacognosy, pharmacology, phytochemistry, natural products and drug discovery.

This new series, Methods in Plant Biochemistry, is an authoritative reference on current techniques in the various fields of plant biochemical research. Each volume in the series, under the expert guidance of a guest editor, addresses a particular group of plant compounds.**The most current and useful methods of analysis are described, with detailed discussions of the development, protocols, and suitability of each technique. Case treatments, diagrams, chemical structures, reference data, and properties are featured where appropriate, along with a full list of references to the specialist literature.**Conceived as a practical companion to the Biochemistry of Plants, edited by P.K. Stumpf and E.E. Conn, no plant biochemical laboratory can afford to be without this comprehensive and up-to-date reference. Addresses the laboratory analysis of all major plant compounds**Illustrates authoritative and detailed practical instructions and recipes for analytical methods**Describes assays suitable for showing biological or pharmacological properties in crude plant extracts

This book describes the processes that are involved in the development of new drugs. The authors discuss the history, role of natural products and concept of receptor interactions with regard to the initial stages of drug discovery. In a single, highly readable volume, it outlines the basics of pharmacological screening, drug target identification, and genetics involved in early drug discovery. The final chapters introduce readers to stem therapeutics, pharmacokinetics, pharmacovigilance, and toxicological testing. Given its scope, the book will enable research scholars, professionals and young scientists to understand the key fundamentals of drug discovery, including stereochemistry, pharmacokinetics, clinical trials, statistics and toxicology.

Natural Products have been important sources of useful drugs from prehistoric times to the present. This book gives an overview about this field and provides important recent contributions to the discovery of new drugs generated by research on natural products. Total synthesis of natural products with interesting biological activities is paving the way for the preparation of new and improved analogs. The methods of combinatorial chemistry permit the selection of the best drug from a large number of candidates. Beyond synthesis and evaluation of organic molecules a number of new bioorganic methods are coming to the fore and will be discucced in this isue of the ERnst schering Research Foundation workshop proceedings.

Infant formulas are unique because they are the only source of nutrition for many infants during the first 4 to 6 months of life. They are critical to infant health since they must safely support growth and development during a period when the consequences on inadequate nutrition are most severe. Existing guidelines and regulations for evaluating the safety of conventional food ingredients (e.g., vitamins and minerals) added to infant formulas have worked well in the past; however they are not sufficient to address the diversity of potential new ingredients proposed by manufacturers to develop formulas that mimic the perceived and potential benefits of human milk. This book, prepared at the request of the Food and Drug Administration (FDA) and Health Canada, addresses the regulatory and research issues that are critical in assessing the safety of the addition of new ingredients to infants.
