Download or read book DNA Topoisomerases in Cancer Therapy written by Toshiwo Andoh and published by Springer Science & Business Media. This book was released on 2003-06-30 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume commemorates the 30th anniversary of the discovery in 1971 of the first DNA topoisomerases, i.e topoisomerase I in E. coli, then provisionally named `omega' protein, by the pioneering work of Jim Wang at Harvard University, who has contributed an article to this volume: `Reflections on an accidental discovery' of the enzyme. Many kinds of topoisomerase have since been found from type I through to type VI in a variety of organisms ranging from viruses to higher eukaryote mammals. The wide distribution of enzymes in various forms of life implies that the DNA topoisomerase is essential for life. In the mid 80's type I and II enzymes were found to be the intracellular targets of a number of efficacious anticancer drugs such as doxorubicin, mitoxantrone, etoposide and camptothecin as a result of a continued efforts of many investigators, especially Leroy Liu and his collaborators at Johns Hopkins University. Readers will find a series of chapters written by researchers actively engaged in the expanding field of topoisomerase and their inhibitors. The series of chapters cover review articles on pharmacology and the molecular mechanism of topoisomerase I- and II-targeting anticancer drugs in mammals and in the yeast Saccharomyces cerevisiae, which has proved to be a superb model organism for studies of anticancer drugs. This volume compiles up-to-date information on the topoisomerase-targeting compounds in clinical and preclinical development as a useful and important reference book for students and researchers in the field of pharmacology, toxicology, oncology and molecular biology.

Download or read book Fluorine and Health written by Alain Tressaud and published by Elsevier. This book was released on 2008-06-06 with total page 821 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluorine and Health presents a critical multidisciplinary overview on the contribution of fluorinated compounds to resolve the important global issue of medicinal monitoring and health care. The involved subjects are organized in three thematic parts devoted to Molecular Imaging, Biomedical Materials and Pharmaceuticals. Initially the key-position of partially fluorinated low molecular weight compounds labelled either with the natural 19F-isotope for Magnetic Resonance Imaging (MRI) or labelled with the radioactive [18F]-isotope for Positron Emission Tomography (PET) is highlighted. Both non-invasive methods belong to the most challenging in vivo imaging techniques in oncology, neurology and in cardiology for the diagnosis of diseases having the highest mortality in the industrialized countries. The manifold facets of fluorinated biomaterials range from inorganic ceramics to perfluorinated organic molecules. Liquid perfluorocarbons are suitable for oxygen transport and as potential respiratory gas carriers, while fluorinated polymers are connected to the pathology of blood vessels. Another important issue concerns the application of highly fluorinated liquids in ophthalmology. Moreover, fluorine is an essential trace element in bone mineral, dentine and tooth enamel and is applied for the prophylaxis and treatment of dental caries. The various origins of human exposure to fluoride species is detailed to promote a better understanding of the effect of fluoride species on living organisms.Medicinally relevant fluorinated molecules and their interactions with native proteins are the main focus of the third part. New molecules fluorinated in strategic position are crucial for the development of pharmaceuticals with desired action and optimal pharmacological profile. Among the hundreds of marketed active drug components there are more than 150 fluorinated compounds. The chapters will illustrate how the presence of fluorine atoms alters properties of bioactive compounds at various biochemical steps, and possibly facilitate its emergence as pharmaceuticals. Finally the synthetic potential of a fluorinase, the first C-F bond forming enzyme, is summarized. - New approach of topics involving chemistry, biology and medicinal techniques - Transdisciplinar papers on fluoride products - Importance of fluoride products in health - Updated data on specific topics

Download or read book Mechanism of Action of Antimicrobial and Antitumor Agents written by J. F. Snell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the third in the series devoted to Antibiotics initiated by Springer Verlag in 1967. The first two volumes were devoted to the Mode of Action of Antibiotics and Biogenesis, respectively and were received graciously. During the intervening years these two works have been used often by research workers and students alike and have been quoted extensively. Although a number of other excellent treatises on antibiotics have appeared, the Springer series has set a standard for thoroughness and quality that meets the need of the scientific community. It is against this background that the present Editors set about the preparation of a third volume in the Series on Antibiotics. Since the appearance of Volume I, also dealing with Mechanism of Action, tremendous strides have been made in the depth and breadth of our knowledge of molecular biology, microbial chemistry and molecular pharmacology and of their direct application to studies on the mode of action of drugs. The field of molecular biology itself was in its relative infancy during the preceding decade and the unique role played by many anti biotics in the development of our understanding of nucleic acid synthesis and function and its relationship to protein synthesis and cell physiology has led rapidly to a very precise, understanding of how many of these same antibiotics inhibit susceptible cells.
