Download or read book Synthesis and Anion Binding Studies of Pyrazole and Biimidazole containing Receptors written by Bobbi Linden Rubin and published by . This book was released on 2005 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation covers two different topics within the area of diaza-containing aromatic five-membered rings: biimidazoles and pyrazoles. With the exception that both these subject matters are explored in the context of developing new anion binding agents, the background and research associated with these two topics are vastly different and will be treated as such. Chapter two, dealing with biimidazoles, focuses solely on expanded porphyrins, while chapter three discusses pyrazoles as potential macrocyclic building blocks and as diamidic-functionalized anion binders. The first chapter covers several different topics in order to put into perspective the diverse subject matter presented in this dissertation. It begins with an overview of some well-known expanded porphyrins. The synthesis, classical applications, and newer studies of the biimidazole synthetic efforts are then described. The third part of the introductory chapter covers the synthesis and applications of pyrazoles. The use of heterocycles with more than one heteroatom in the construction of expanded porphyrins is just beginning to be explored, and is the focus of chapter two. The synthesis of a novel expanded porphyrin is described and its applications are investigated. More specifically, chapter two covers the synthesis of several biimidazole dialdehydes and their condensation with three 3,3',4,4'-functionalized bis-[alpha]-free bipyrroles to form a series of novel macrocycles. The characterization of these new compounds has been investigated and is discussed in detail. Also presented are preliminary studies of their anion binding properties. Pyrazoles, the subject of chapter three, are another overlooked class of potential building blocks in the area of expanded porphyrins and molecular recognition chemistry. Pyrazoles have rarely been reported in the literature as being part of a larger molecular framework. Until this work, their anion binding potential had remained unexplored. Thus, the attempted incorporation of a pyrazole fragment into an expanded porphyrin framework is described. Second, and more significantly, the design, synthesis, and anion binding properties of a new series of diamidic pyrazoles are reported.

Available in PDF, EPUB and Kindle. Book excerpt: Chelation Therapy in the Treatment of Metal Intoxication presents a practical guide to the use of chelation therapy, from its basic chemistry, to available chelating antidotes, and the application of chelating agents. Several metals have long been known to be toxic to humans, and continue to pose great difficulty to treat. These challenges pose particular problems in industrial settings, with lead smelting known to be associated with hemopoietic alterations and paralyses, and the inhalation of mercury vapor in mercury mining being extremely detrimental to the central nervous system. Clinical experience has demonstrated that acute and chronic human intoxications with a range of metals can be treated efficiently by administration of chelating agents. Chelation Therapy in the Treatment of Metal Intoxication describes the chemical and biological principles of chelation in the treatment of these toxic metal compounds, including new chelators such as meso-2,3-dimercaptosuccinic acid (DMSA) and D,L-2,3-dimercapto-1-propanesulfonic acid (DMPS). Presents all the current findings on the potential for chelation as a therapy for metal intoxication Presents practical guidelines for selecting the most appropriate chelating agent Includes coverage on radionuclide exposure and metal storage diseases Describes the chemical and biological principles of chelation in the treatment of toxic metal compounds

This book was released on 2012-12-06 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop on "The structure of small molecules and ions" was held at the Neve-Han guest house, near Jerusalem, Israel on December 13 to 18 in mem ory of the late Professor Itzhak Plesser. Professor Plesser played a central role in the research done both at the Weizmann Institute and at Argonne National Laboratories on the "Coulomb explosion" method. His friends honored his memory by organizing a meeting in which subjects related to Plesser's interests would be discussed. Just a week be fore the conference started we were struck by another tragedy -the death of our graduate student Ms. Hana Kovner, who participated in many of the Coulomb explosion experiments at the Weizmann Institute. We would like to dedicate these proceedings to her memory as well. The goal of the workshop was to bring together chemists and physicists working on different aspects of the structural problems of small molecular en tities. The time seemed appropriate for discussing experimental and theoretical concepts, since in recent years new methods have been introduced, and a large amount of information has been accumulated on systems not studied before, like unstable molecules, ions, van der Waals molecules and clusters. The program of the workshop reflects, we believe, these new developments. The meeting was characterized by intensive discussions in which the weak nesses and strengths of new and of well established concepts were revealed. We hope that it measured up to the high standards Itzhak Plesser maintained all through his scientific life.
