Available in PDF, EPUB and Kindle. Book excerpt: The development of agents capable of cleaving RNA and DNA has attracted considerable attention from researchers in the last few years, because of the immediate and very important applications they can find in the emerging fields of biotechnology and pharmacology. There are essentially two classes of these agents - nucleases that occur naturally inside cells and synthetically produced artificial nucleases. The first class includes protein enzyme nucle ases and catalytic RNA structured ribozymes that perform cleavage of the phosphodiester bonds in nucleic acids according to a hydrolytic pathway in the course of different biochemical processes in the cell. A different pathway is used by some antibiotics which cleave DNA via redox-based mechanisms resulting in oxidative damage of nucleotide units and breakage of the DNA backbone. The above molecules are indispensable tools for manipulating nucleic acids and processing RNA; DNA-cleaving antibiotics and cytotoxic ribonucleases have demonstrated utility as chemotherapeutic agents. The second class, artificial nucleases, are rationally designed to imitate the active centers of natural enzymes by simple structures possessing minimal sets of the most important characteristics that are essential for catalysis. A dif ferent approach, in vitro selection, was also used to create artificial RNA and DNA enzymes capable of cleaving RNA. Being less efficient and specific as compared to the natural enzymes, the primitive mimics are smaller and robust and can function in a broad range of conditions.

Download or read book Metallotherapeutic Drugs and Metal Based Diagnostic Agents written by Marcel Gielen and published by John Wiley & Sons. This book was released on 2005-09-01 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are an astonishing number and variety of roles that metals play in contemporary medicine. This book contains information on the medicinal uses of inorganics, that is, of elements such as boron, lithium, selenium, to name a few, as well as metal-containing species. In keeping with the notion that healthy mammals rely on (bio-essential) metals for the normal functioning of approximately a third of their proteins and enzymes, a large number of drugs are metal-based and considerable effort is being devoted to developing both second- and third-generation drugs as well as generating novel metal-based drugs. While there is no doubt that there is an emphasis on 'Metallotherapeutics' throughout the volume, the use of metals in medicine is not restricted to metal-based drugs. The following are also covered: non-invasive radiopharmaceuticals Magnetic Resonance Imaging (MRI) mineral supplements From the foregoing and, more importantly, from the contents of the various Chapters, the reader will gain an appreciation of the very real role metal-based drugs play in modern medicine and of the considerable effort being devoted to the development of novel complexes with greater efficacy as therapeutic and diagnostic agents.

Download or read book Vanadium in Biological Systems written by N.D. Chasteen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, vanadium has increasingly attracted the interest of biologists and chemists. The discovery by Henze in 1911 that certain marine ascidians accumulate the metal in their blood cells in unusually large quantities has done much to stimulate research on the role of vanadium in biology. In the intervening years, a large number of studies have been carried out to investigate the toxicity of vanadium in higher animals and to determine whether it is an essential trace element. That vanadium is a required element for a few selected organisms is now well established. Whether vanadium is essential for humans remains unclear although evidence increasingly suggests that it probably is. The discovery by Cantley in 1977 that vanadate is a potent inhibitor of ATPases lead to numerous studies of the inhibitory and stimulatory effects of vanadium on phosphate metabolizing enzymes. As a consequence vanadates are now routinely used as probes to investigate the mechanisms of such enzymes. Our understanding of vanadium in these systems has been further enhanced by the work of Tracy and Gresser which has shown striking parallels between the chemistry of vanadates and phosphates and their biological compounds. The observation by Shechter and Karlish, and Dubyak and Kleinzeller in 1980 that vanadate is an insulin mimetic agent has opened a new area of research dealing with the hormonal effects of vanadium. The first vanadium containing enzyme, a bromoperoxidase from the marine alga Ascophyllum nodosum, was isolated in 1984 by Viltner.

This book was released on 2018-03-07 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2018 in the subject Chemistry - Anorganic Chemistry, grade: 10, , language: English, abstract: Nanoscience is the study of phenomena exhibited by materials at atomic, molecular and macromolecular levels, of dimensions ranging from a few nanometres to less than a hundred nanometres. In chemistry, this size range has been associated with colloids, micelles, polymer molecules and similar structures. In physical and electrical engineering, nanoscience is often associated with quantum behaviour, and electron behaviour in nanoscale structures. The area of research in the field of nanotechnology is as diverse as physics, chemistry, material science, microbiology, biochemistry and also molecular biology. The interface of nanotechnology in combination with biotechnology and biomedical engineering has emerged with the use of nanoscale structures in diagnosis, gene sequencing, and drug delivery. Nanoparticles have attracted great interest in recent years because of their unique chemical and physical properties, which are different from those of either the bulk materials or single atoms. Nanostructure materials have potential applications in ceramics, optoelectronics and catalysis. Research on the synthesis of nanomaterials using metal complexes as precursors have been less reported. Application of metal complexes as precursors may be helpful to control the physical properties of metal nanoparticles. In the last few years, researchers have characterized the tunable properties by altering the nanostructure size, shape, and chemical composition and have developed reproducible strategies to make nanostructures of desired properties. It has been already proved that by controlling the size of the particle and manipulating surface structures of the semiconductor materials, the electronic, magnetic, mechanical, and chemical properties can be modified to suit a wide range of device application in many fields. The present book deals with the synthesis of Schiff base complexes of Cd(II), Zn(II) and Hg(II) with different sulphur containing ligand and preparation of metal sulphide nanoparticle by the thermal decomposition of complex precursor. During this academic journey four new sulphur containing ligands and their thirty complexes were synthesized. These ligands and complexes were characterized by spectroscopic methods like UV-Vis, FT-IR, 1H-NMR, 13C-NMR, 2D-NMR, FAB-MS / ESI-Ms spectra.
