Download or read book Copper Bioinorganic Chemistry From Health To Bioinspired Catalysis written by Jalila Simaan and published by World Scientific. This book was released on 2023-07-26 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioinorganic chemistry is an interdisciplinary research field which centers on metals in biology. Over the past few decades, advances in chemistry, biology as well as in spectroscopic methods have shed light on the role of copper in human pathologies and allowed the growing discovery of copper-containing biological systems. Following this trend, much effort is being constantly chanelled towards understanding these fundamental biological processes or enzymes. In addition, chemists are developing molecules to target copper or copper enzymes as therapeutic tools. On the other hand, inspired by the function of biological systems, small molecular weight complexes inspired by the active site of copper enzymes are being prepared and studied. These bioinspired complexes can function both as mechanistic tools and as functional catalysts for oxidative transformations.The seven chapters in this book, contributed by internationally recognized authors cover recent developments on these aspects illustrated by interdisciplinary fields from biology, chemistry, spectroscopy to bioinspired catalysis. It contains aspects ranging from human health issues (copper homeostasis in bacteria and the development of molecules as anticancer or antibacterial agents) to bioinspired catalysis.

Download or read book Steric Control in Copper I Thioether Coordination Chemistry written by Keily Heredia and published by . This book was released on 2006 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tetradentate thioether Si(CH[subscript]2SBu[superscript]t)[subscript]4 was used to synthesize the complete series of copper(I) complexes Cu[subscript]2Si(CH[subscript]2SBu[superscript]t)[subscript]4X[subscript]2 (X = C1, Br, I). Interestingly, a single X-ray diffraction study of the chloro derivative revealed the presence of both four-coordinate tetrahedral and three-coordinate trigonal planar copper centers. The adamantyl-substituted dithioether Me[subscript]2Si(CH[subscript]2SAd)[subscript]2 has been readily synthesized and it is the first member of the Me[subscript]2Si(CH[subscript]2SR)[subscript]2 (R = alkyl, aryl) family of ligands to be structurally characterized. Reactivity studies towards monovalent coinage metal ions have produced simple 1:1 and 1:2 complexes {Me[subscript]2Si(CH[subscript]2SAd)[subscript]2}CuX (X = C1, Br, I), and [Cu{Me[subscript]2Si(CH[subscript]2SAd)[subscript]2}[subscript]2]PF[subscript]6. Significantly, the bulky substituents on the thioether preclude the generation of polymeric species such as those isolated for R = Me and result instead in the formation of rare examples of three-coordinate trigonal planar Cu(I) thioether complexes. Furthermore, these are the first such complexes exhibiting [CuS[subscript]2X] coordination spheres. In a similar vein, the dinuclear gold complexes Au[subscript]2{Me[subscript]2Si(CH[subscript]2SAd)[subscript]2}X[subscript]2 (X = C1, Br), each of which displays a fairly strong intramolecular Au...Au aurophilic interaction, are obtained instead of the polymeric species isolated for closely related but less sterically demanding thioether ligands [e.g., Me[subscript]2Si(CH[subscript]2SMe)[subscript]2]. The new complexes have been characterized by a variety of analytical and spectroscopic techniques, including electrospray ionization mass spectroscopy (ESIMS). An overview of the coordination chemistry of Me[subscript]2Si(CH[subscript]2SAd)[subscript]2 towards other transition metal ions such as Ag(I), Cd(II) and Hg(II) will be also discussed.

This book was released on 2012-02-02 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of electrochemical techniques by chemists, particularly those who regard themselves as "inorganic" coordination chemists, has undergone a very rapid growth in the last 15-20 years. The techniques, as dassically applied to inorganic species, had their origins in analytical chemistry, and the methodology had assumed, until the mid 60s, more importance than the chemiStry. However, the growth of interest in coordination compounds (including organometallic complexes) having unusually rich of electron-transfer in bio-inorganic redox properties, and in the understanding species, has propelfed electro-chemistry into the foreground of potentially readily available techniques for application to a very wide range of problems of interest to those chemists. This growth has been fuelled additionally by the availability of relatively cheap equipment of growing sophistication and by an increase in the "inorganic" chemists' general knowledge of physical electrochemistry. In particular, with increasing availability and sophistication of eqUipment, kinetic problems are now being addressed, and the range of electrode types and configuration and solvents has been greatly expanded. Furthermore, the rapid expansion of interest in biological problems has opened new avenues in functionalisation of electrodes, in the development of sensory devices and, in a sense, a return to the analytical base of the science, using novel and multi-disciplinary techniques drawing on synthesis chemistry of and electronic micro-engeneering. The drive towards increasing use microcomputer-controlled data analysis and the development of microeledrodes has opened exciting new avenues for the exploration of chemical reactions involving electron-transfer processes.

Download or read book Biology of Copper Complexes written by John R. J. Sorenson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1928, it was discovered that copper was essential for normal human metabolism. Ten years later, 1938, it was observed that patients with rheumatoid arthritis had a higher than normal serum copper concentration, which returned to normal wi th remission of this disease. Thirteen years later, it was found that copper complexes were effective in treating arthritic diseaseS. The first report that copper complexes had antiinflammatory activity in an animal model of in flammation appeared twenty-two years after the discovery of essen tiality. In 1976, it was suggested that the active forms of the anti arthritic drugs are their copper complexes formed in vivo. This suggestion was confirmed and extended in the interim with over 1000 recent publications, and many of these were addressed in the proceed ings of our first symposium, published in 1982. The present symposium was organized to present new normal physiological, nutritional, and biochemical aspects of essential metal loelement metabolism as well as variations in metabolism associated with disease states. In addition new data concerning antimicrobial, antiinflammatory, antiulcer, anticancer, anticarcinogenic, analgesic, and radioprotectant activities of copper complexes were presented. These activities are consistent with the notion that they represent the facilitation of normal copper-dependent metabolic processes in dis ease states. The presentations and interactive discussions that fol lowed are contained in these proceedings. John R. J. Sorenson Dedication These proceedings are dedicated to those who made this truly memorable scientific and social Arkansas experience possible.

This book was released on 2015-06-13 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis addresses the coordination chemistry and reactivity of copper and gold complexes with a focus on the elucidation of (i) the metal-mediated activation of σ-bonds and (ii) the migratory insertion reaction. Both processes are of considerable importance in organometallic chemistry, but remain elusive for Cu and Au complexes. In this work, the author contributes significant advances: The first σ-SiH complexes of copper are experimentally and computationally characterized, yielding valuable insights into σ-bond activation processes for copper. Evidence for a highly unusual migratory syn insertion of unsaturated organic molecules into the gold-silicon bond of silylgold (I) complexes is provided and the corresponding mechanism identified. The intermolecular oxidative addition of σ-SiSi, σ-CC and σ-CX (X=halogen) bonds with molecular gold (I) complexes is studied in detail, effectively demonstrating that this reaction, usually considered to be impossible for gold, is actually highly favored, provided an adequate ligand is employed. The use of small-bite angle bis (phosphine) gold (I) complexes allows for the first time the oxidative addition of σ-CC and σ-CX bonds for gold (I). These results shed light on an unexpected reactivity pattern of gold complexes and may point the way to 2-electron redox transformations mediated by this metal, opening up new perspectives in gold catalysis.
