Download or read book Organic Sulfur Compounds written by N. Kharasch and published by Elsevier. This book was released on 2013-10-22 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic Sulfur Compounds, Volume I deals with the chemistry of organic sulfur compounds such as disulfides, polysulfides, olefins, acetylenes, and chloroethylenes. Topics covered range from the inorganic acids of sulfur and the thermodynamics of organic sulfur compounds to some applications of isotopic sulfur and the stereochemistry of disulfides and polysulfides. The mechanism of oxidation of thiols to disulfides is also discussed. Comprised of 40 chapters, this volume first considers the precise structures of elemental sulfur in relation to the reactions of sulfur compounds, followed by an analysis of the inorganic acids of sulfur. The reader is then introduced to the thermodynamics of organic sulfur compounds and the bonding characteristics of the sulfur atom, as well as the infrared spectra of organosulfur compounds. Subsequent chapters focus on the ionic scission of the sulfur-sulfur bond; nucleophilic reactions of thiols with acetylene and chloroethylene; reactions of sulfur with olefins; and the chemistry of isothiocyanates. This book should prove useful to advanced students, practitioners, and research workers in the field of organic chemistry.
Book Synopsis Veterans at Risk by : Institute of Medicine
Download or read book Veterans at Risk written by Institute of Medicine and published by National Academies Press. This book was released on 1993-02-01 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently, World War II veterans have come forward to claim compensation for health effects they say were caused by their participation in chemical warfare experiments. In response, the Veterans Administration asked the Institute of Medicine to study the issue. Based on a literature review and personal testimony from more than 250 affected veterans, this new volume discusses in detail the development and chemistry of mustard agents and Lewisite followed by interesting and informative discussions about these substances and their possible connection to a range of health problems, from cancer to reproductive disorders. The volume also offers an often chilling historical examination of the use of volunteers in chemical warfare experiments by the U.S. militaryâ€"what the then-young soldiers were told prior to the experiments, how they were "encouraged" to remain in the program, and how they were treated afterward. This comprehensive and controversial book will be of importance to policymakers and legislators, military and civilian planners, officials at the Department of Veterans Affairs, military historians, and researchers.

Book Synopsis Chemico-biological Interactions of Sulfide and Organosulfur Compounds [microform] by : Mohammad Ali Eghbal
Download or read book Chemico-biological Interactions of Sulfide and Organosulfur Compounds [microform] written by Mohammad Ali Eghbal and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 2004 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exposure of isolated hepatocytes to NaHS led to GSH depletion. CYP450 inhibitors were protective against NaHS toxicity and prevented GSH depletion. Methionine was protective against NaHS and its effect was overcome by inhibition of S-adenosyl-L-homocysteine hydrolase by adenosine. This suggests that S-adenosyhnethionine dependent methylation can detoxify H2S in the liver. The H 2O2 scavengers were protective against H2S toxicity. H2S induced ROS formation was dose dependent and pyruvate inhibited this ROS production. Nontoxic concentrations of H2S enhanced the cytotoxicity of H2O2 generated by glucose/glucose oxidase, which was inhibited by CYP450 inhibitors. Furthermore hepatocyte ROS formation induced by H2S was decreased by CYP450 inhibitors cimetidine and benzyleimidazole. Therefore CYP450-dependent metabolism of H2S is responsible for inducing ROS production. H2S induced cytotoxicity was preceded by mitochondrial depolarization. In this project, two aspects of the action of hydrogen sulfide and reactive sulfur species have been studied: cytotoxic and cytoprotective effects. Freshly isolated hepatocytes have been used in order to examine the prevalence and mechanisms of the different sulfide dependent processes that influence cell survival and death. Our hypothesis is that the exogenous application of high concentrations of HS and other reactive sulfur species to isolated hepatocytes in the presence of various modulators will provide a rapid mechanism dependent screen for ways in which reactive sulfur species can modulate cell survival and death. NaHS and/or garlic/onion derived organosulfur compounds, Allyl mercaptan (AM) and Propyl mercaptan (PM) protected hepatocytes against hydroquinone, methylbenzoquinone, and 5-hydroxynaphtoquinone. NaHS and mercaptans increased the cytotoxicity of tert-butylhydroquinone. Treatment of these benzoquinones with allyl mercaptan, propanethiol or NaHS led to formation of new compounds which by MS/MS analysis were identified as mercaptan conjugates of corresponding hydroquinones. (Abstract shortened by UMI.)H2S, allyl mercaptan (AM), propyl mercaptan (PM), diallyl disulfide (DADS) and diallyl sulfide (DAS) prevented hepatocyte toxicity induced by allyl alcohol, 1-bromoethanol and their toxic metabolites. MS/MS spectrometry revealed adduct formation between AM and/or PM with the acrolein and/or haloacetaldehyde formed by the metabolism of allyl alcohol and alpha-haloethanol. H 2S or garlic and onion mercaptans are cytoprotective by trapping toxic aldehyde metabolites and/or by preventing lipid peroxidation.

Book Synopsis Biochemistry of Sulfur by : Ryan J. Huxtable
Download or read book Biochemistry of Sulfur written by Ryan J. Huxtable and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: There can be few elements with a biochemistry as coherent as that of sulfur. This important element is crucial to myriad aspects of metabo lism, catalysis, and structure. The plurality of functions in which sulfur is involved derives squarely from the numerous oxidation states in which it may exist, some having great stability, some being capable of ready redox interconversions, and yet others having great instability. As a result, the flux of sulfur from the geosphere through the various kingdoms of life leaves few biochemical processes unaffected. Although there are large gaps in the fabric of our basic knowledge of sulfur biochemistry, it is sufficiently framed to allow a unified and organized story, a story which many of the best-known names in bio chemistry have helped to write. It has been both a task and a privilege to try and summarize this story, one that is enormous, complex, fast moving, still developing and, above all, exciting. I suppose that no mo nographer of such a vast subject could be satisfied with his efforts. It is unfortunately probable that in attempting this task I have made as many errors as a Stilton cheese has blue streaks, and as many omissions as a Swiss cheese has holes. Perfection is not to be achieved in a monograph. Inasmuch as I have succeeded, the credit belongs to those whose efforts gave us the knowledge we have. Where I have failed, the fault is only mine.
