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.

Book Description :

More than one hundred short-term bioassays are now available for detecting the toxicity, mutagenicity, and potential carcinogenicity of chemicals. These bioassays were developed and validated with individual compounds, and their principal application was perceived to be in evaluating the health hazard of such materials. However, man is rarely exposed to single chemicals; his exposure to hazardous chemicals is more commonly a multifactorial phenomenon. Although chemical analysis can be used to detect known hazardous compounds, it would be a staggering and expensive task to analyze large numbers of samples for all known or suspected hazardous constituents. Furthermore, the biological activity of a complex mixture cannot be reliably predicted from knowledge of its components. On the other hand, bioassays alone cannot tell us which components of complex mixtures are responsible for the biological activity detected. Thus, cost effectiveness and technical feasibility dictate stepwise and perhaps iterative application -of both chemical and biological methods in evaluating the health effects of complex environmental mixtures. Through the coupling of reliable biological detection systems with methods of chemical fractionation and analysis, it is frequently possible to isolate the individual chemical species that show biological activity. Initially, complex mixtures may be separated and bioassayed in carefully defined chemical fractions. The results of such short-term screening bioassays then may be used td guide the course of further fractionation and to determine the need for more stringent and comprehensive biological testing.

Book Description :

With this proceedings of the fourth symposium on complex mixtures, we continue to revise and extend our knowledge of genetic methods for the evaluation of chemical mixtures in the environment. The early chapters of this volume are devoted to new bioassay techniques that are directly applicable to the monitoring of environments contaminated with genotoxic chemicals. Microbiological methods have been further refined to meet the special needs of atmospheric monitoring so that very small samples may now be efficiently tested. New in situ methods utilizing green plants actually avoid many of the usual difficulties of sample collection and preparation and offer special advantages in monitoring wastewater, sludges, and hazardous wastes. Insects also are being employed very effectively in the evaluation of gaseous air pollutants in controlled laboratory investigations. Increased emphasis has been placed on a comprehensive assessment of the potential of complex mixtures t9 cause various kinds of genetic damage. New assays for chromosome structural and numerical aberrations in mammalian cells in vitro have been developed and are being applied in laboratory studies. Efforts to link tests for gene mutation and cell transformation in vitro with assays for tumorigenesis in vivo are contributing to the validation of the short-term testing approach. Studies comparing in vitro and in vivo data on a coal conversion by-product, on polycyclic aromatic hydrocarbons, and on mineral fibers are reported in separate papers. Later chapters are devoted to investigations on the fractionation and biological evaluation of specific chemical components within complex mixtures.

Cytochemical Bioassays: Techniques and Clinical Applications describes the techniques and clinical applications of cytochemical bioassays, particularly with respect to polypeptide hormones. This book discusses the clinical and research implications of studies that use these techniques. This text is comprised of 14 chapters; the first of which introduces the reader to the origins and general principles of cytochemical bioassays, along with their advantages. This discussion is followed by a chapter that explains what is meant by ""an assay""; for what purpose assays are done; the basic components of an assay method; and the nature of the difference between in vivo and in vitro hormone bioassays, in vitro ligand assays, and enzyme assays. Attention then turns to the techniques of cytochemical bioassays and the cytochemical bioassay procedures for adrenocorticotropic hormones; thyroid-stimulating hormones; the thyroid-stimulating antibody of Graves' disease; thyroid growth stimulating and blocking immunoglobulins; and luteinizing hormones. The next chapters focus on the technique and clinical relevance of a cytochemical bioassay for gastrin-like activity and for measurement of antidiuretic hormones, parathyroid hormones, angiotensin II, natriuretic hormones, and hypothalamic regulating hormones. This book will be of interest to clinicians and practitioners of biology, biochemistry, and endocrinology.

The Statistics of Bioassay: With Special Reference to the Vitamins, Volume II focuses on the processes, reactions, principles, and approaches involved in the biological assay of vitamins. The publication first offers information on the general principles of biological assay, dosage-response curve and its error, and designs for segregating nonrandom variation. Discussions focus on replacement of missing values, randomized groups, calculation of the line, analysis of the variation about the line, comparative biological assays, analytical biological assays, and determination of activity. The text then ponders on measurement of relative potency and correction of quantitative variables. The manuscript takes a look at assays where the variation in response is a function of the dose and slope-ratio assays. Topics include microbiological assays and the slope-ratio technique, analysis of balanced slope-ratio assays, analysis of assays with an all-or-none response, and graded response with unequal variance. The publication then tackles multiple or repeated assays, including quality control in repeated assays and combination of independent assays of a single unknown. The publication is a valuable source of information for researchers interested in the biological assay of vitamins.
