Download or read book Coordination Chemistry of Macrocyclic Compounds written by Gordon Melson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemists have been aware of the existence of coordination compounds con taining organic macrocyclic ligands since the first part of this century ; however, only during the past few years have they expanded research into the chemistry of these compounds. The expansion was initiated in the early 1960s by the synthesis and characterization of compounds containing some new macrocyclic ligands. The synthesis of compounds which may serve as model systems for some natural products containing large rings as ligands provided the main goal for the early expansion of research effort; indeed, a recurrent theme behind much of the reported chemistry has been the analogy between synthetic macrocyclic compounds and many natural-product systems. More recently, the emphases of reported research have ranged over the whole spectrum of chemistry, and the number of publications that discuss macrocyclic chemistry has increased at a dramatic rate. The completed research has been reported in a variety of journals throughout the world but there has been no previous attempt to bring the major developments together under one cover. This book, therefore, attempts to satisfy the need for a single source in which there is both a collection and a correlation of information concerning the coordination chemistry of macrocyclic compounds. The chapters in this book discuss various aspects of macrocyclic chemistry, and while these chapters as a whole constitute an in-depth survey of the state-of the-art of the field, each chapter is written as a complete unit.

Download or read book Redox-Active Therapeutics written by Ines Batinić-Haberle and published by Springer. This book was released on 2016-10-13 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: This essential volume comprehensively discusses redox-active therapeutics, focusing particularly on their molecular design, mechanistic, pharmacological and medicinal aspects. The first section of the book describes the basic aspects of the chemistry and biology of redox-active drugs and includes a brief overview of the redox-based pathways involved in cancer and the medical aspects of redox-active drugs, assuming little in the way of prior knowledge. Subsequent sections and chapters describe more specialized aspects of central nervous system injuries, neurodegenerative diseases, pain, radiation injury and radioprotection (such as of brain, lungs, head and neck and erectile function) and neglected diseases (e.g., leishmaniasis). It encompasses several major classes of redox-active experimental therapeutics, which include porphyrins, salens, nitrones, and most notably metal-containing (e.g., Mn, Fe, Cu, Zn, Sb) drugs as either single compounds or formulations with nanomaterials and quantum dots. Numerous illustrations, tables and figures enhance and complement the text; extensive references to relevant literature are also included. Redox-Active Therapeutics is an invaluable addition to Springer’s Oxidative Stress in Applied Basic Research and Clinical Practice series. It is essential reading for researchers, clinicians and graduate students interested in understanding and exploring the Redoxome—the organism redox network—as an emerging frontier in drug design, redox biology and medicine.

Download or read book Expanded, Contracted & Isomeric Porphyrins written by Jonathan L. Sessler and published by Elsevier. This book was released on 1997 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paperback. The porphyrins are a class of naturally-occurring macrocycles and are ubiquitous in our world. As such, they have been called the Pigments of Life. This auspicious designation reflects their importance in numerous biological functions. Indeed, life as we understand it relies on the full range of biological processes that are either performed by or catalyzed by porphyrin-containing proteins. Chlorophyll-containing photosynthetic reaction centers in plants, for instance, convert light energy into chemical energy while producing oxygen along the way. It is this oxygen, evolved from photosynthesis, that is transported, stored, and reduced by heme-containing proteins in many organisms, including mammals. Not surprisingly, therefore, these molecules remain of fundamental interest to chemists and biochemists. Indeed, they continue to be intensely investigated by researchers world-wide.Inspired by the importance of the porphyrins, a new research di

Download or read book Depleted Uranium Induced Petkau Effect written by Svetlana Zunic and published by Nova Science Publishers. This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this study is to contribute to a better understanding of the interaction of depleted uranium as a source of low dose radiation with the living world and humans in a contaminated environment. There has been increased interest in biological effects of low dose radiation after the incident in Chernobyl. Uncertainty of epidemiological studies about the health effects of low-dose radiation arises from the fact that the biological effects of low-dose radiation do not relate obligatory to DNA damage. Military use of depleted uranium (DU) for decades put the problem of low-dose radiation exposure in the spotlight. The explanation related to the limited effects of Ñ-emitting nuclear weapons, including DU, was based to some extent on the fact that alpha particles have a short track in air. This paradigm has changed with the realisation that nano- and micro-sized particles of DU could have a global atmospheric movement. The idea about the spreading of uranium particles through air masses across the globe arose from the results of air pollution measurement. Due to uncontrolled military use of high amounts (a thousand tons) of depleted uranium, numerous unusual environmental physical manifestations were recorded in the last two or three decades. Simultaneous monitoring of natural phenomena on Earth and in the atmosphere has revealed an exceptional parallelism between the phenomena in the environment and in the living world. Our knowledge has evolved from in-vitro studies of radiation exposure to a more comprehensive understanding of unexpected and poorly understood natural phenomena, whose consequences may be achievable according to the theory of litosphere-atomsphere-ionospehere and biosphere coupling. The emission of radiation in the course of several decades due to corrosion of scattered remnants of DU armaments, which has been intensified by the repeated bombing of the regions within the range of the transfer of radioactive particles through the air, strikes a broad territory and numerous populations, and unavoidably leads to in-vivo Petkau effect. The Petkau effect is a challenge for science to declare the future health strategy with the main goal focused on minimising the early as well as delayed in-vivo effects of depleted uranium. As inhaled air is the main source of internal contamination, further research on this topic is valuable, especially in terms of overcoming inter-individual variability. The authors propose a simple model based on apoptotic parameters and artificial network method for individualised estimation of tissue response to low-dose tobacco exposure. Non-targeted effects of radiation are time-evolving and can lead to delayed health effects, including cancerogenesis. The authors discuss the importance of an individual approach to the diagnosis and selection of appropriate therapy, based not only on the results of the expression analysis, but also on metabolic and apoptotic tissue properties. Humanity is the main subject of the authors' study. Understanding the basic principles of cell biology and radiation interaction with living matter is supported by authentic medical data obtained from patients originating from the territories which were geographically close to each other (Serbia and Montenegro seaside, as well as Bosnia and Herzegovina, the territories of the former Yugoslavia).

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.

This book was released on 2012-03-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the middle of the Sixties, new types of formulation for biologically active com pounds have been developed, which have been introduced into the literature under the term Controlled Release Formulations (CRF). Stimulated by results from former and successful pharmaceutical research, which was engaged in the production of prepa rations with protracted effects (introduction onto the market in the year 1952 of D amphetamine in the form of pellets, coated to varying degrees with fats and waxes) 1), experiments were carried out to transfer the prolongation of effectiveness to pesticidal substances also, by means of a depot formulation. Initial work was concerned with the production of protective coatings for sonar systems in marine ecosystems. By means of antifouling paints or rubber coatings containing tri-n-butyl-tin oxide (TBTO), the growth of marine organisms on sonar domes, buoys and hulls in the water could be effectively prevented 2. 3). Controlled release formUlations of pesticides are defined as depot systems which continuously release their toxic constituents into the environment over a specified period of time (usually months to years) 4). According to this definition, such formu lations can be successfully employed where a chronic exposure to biologically active compounds is required over a longer period. The following hypothetical example is intended to illustrate this 5). In Fig. 1, the duration of activity of a non-persistent pesticide with a loss rate under environmental conditions of t1/2 = 15 days, is graphically illustrated.
