Metal chelators are emerging as versatile tool with many medical applications. Their versatility allows them to be used in chelation therapy for treating diseases caused by toxic and heavy metal poisoning, chelating agents are capable of binding to toxic metal ions to form complex structures which are easily excreted from the body removing them from intracellular or extracellular spaces. In addition, metal chelators can also be applied as contrast agents in MRI scanning. Metal Chelation in Medicine provides a clear and timely perspective on the role of chelating agents in the management of metal intoxications and storage diseases. Written by leaders in the field of chelators, this publication is at the cutting-edge of the subject. It covers a broad range of topics such as the use of metal chelators in non-invasive assessment of brain iron overload, and the treatment of systemic iron overload and neurodegenerative diseases. As such it is particularly valuable to clinicians treating metal poisonings and metal storage diseases. However, it is also a useful text for researchers, industry professionals and university students with a specific interest in medicinal chemistry, chelation, metal ions, imaging and non-invasive techniques.

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

Volume 19, entitled Essential Metals in Medicine: Therapeutic Use and Toxicity of Metal Ions in the Clinic of the series Metal Ions in Life Sciences centers on the role of metal ions in clinical medicine. Metal ions are tightly regulated in human health: while essential to life, they can be toxic as well. Following an introductory chapter briefly discussing several important metal-related drugs and diseases and a chapter about drug development, the focus is fi rst on iron: its essentiality for pathogens and humans as well as its toxicity. Chelation therapy is addressed in the context of thalassemia, its relationship to neurodegenerative diseases and also the risks connected with iron administration are pointed out. A subject of intense debate is the essentiality of chromium and vanadium. For example, chromium(III) compounds are taken as a nutritional supplement by athletes and bodybuilders; in contrast, chromate, Cr(VI), is toxic and a carcinogen for humans. The benefi cial and toxic effects of manganese, cobalt, and copper on humans are discussed. The need for antiparasitic agents is emphasized as well as the clinical aspects of metal-containing antidotes for cyanide poisoning. In addition to the essential and possibly essential ones, also other metal ions play important roles in human health, causing harm (like the metalloid arsenic, lead or cadmium) or being used in diagnosis or treatment of human diseases, like gadolinium, gallium, lithium, gold, silver or platinum. The impact of this vibrant research area on metals in the clinic is provided in 14 stimulating chapters, written by internationally recognized experts from the Americas, Europe and China, and is manifested by approximately 2000 references, and about 90 illustrations and tables. Essential Metals in Medicine: Therapeutic Use and Toxicity of Metal Ions in the Clinic is an essential resource for scientists working in the wide range from pharmacology, enzymology, material sciences, analytical, organic, and inorganic biochemistry all the way through to medicine ... not forgetting that it also provides excellent information for teaching.

Chelating Agents and Metal Chelates focuses on the structure and properties of metal chelates, as well as bond types, stereochemistry, and optical phenomena. The selection first offers information on historical background and fundamental concepts and the nature of metal-ligand bond. Discussions focus on the structure and stability of metal chelates, bond types and characteristic properties, classes of acceptor metal atoms, and metal-metal bonds in complex compounds. The text also touches on bidentate chelates, design and stereochemistry of multidentate chelating agents, and optical phenomena in metal chelates. The publication ponders on oxidation-reduction potentials as functions of donor atom and ligand and metal chelates of ethylenediaminetetraacetic acid and related substances. Topics include liquid junction potentials, reversibility, measurement of redox potentials, ethylenediaminetetraacetato chelate couples, and metal chelates of ethylenediaminetetraacetic acid. The text also takes a look at metal chelates in biological systems and physical and coordination chemistry of tetrapyrrole pigments. The manuscript is a vital reference for senior students, research workers, biologists, and medical scientists interested in the chemistry of metal chelates.

This is an easy-to-read manual about chelation therapy. It contains specific protocols for the treatment of chronic metal overexposure, all of which are evidence-based, aiding the inexperienced and the experienced therapist in selecting the optimal chelating agent for the metal(s) in question. Expert chemists and chelation therapists have contributed invaluable knowledge and experience to this book. Most importantly, this is not a book promoting personal views or preferences. In fact, the information presents and explains different approaches, and allows the reader to draw his own conclusion. All the protocols listed have been modified for the treatment of chronic metal intoxication, included are oral and intravenous treatment plans. The authors explain in simple terms how a chelating agent ́s bioavailability affects metal binding and how various protocols such as the Cutler Protocol affect the detoxification process, why DMPS binds mercury and which chelators are useful for the detoxification of certain organ system. Also discussed is the importance and effect of treatment pauses. Diagnostic tests are discussed, and which are useful under certain conditions. Shown are tables comparing the average metal binding ability of the various EDTAs, DMPS, DMSA and other chelating agents. Detailed information explains which chelator binds which metal and why, all of which aids the therapist in finding optimal treatment schedules. Novel chelating agents are presented such as MIADMSA, a new oral chelator specifically designed for arsenic intoxication, or how natural Pectin may be used an alternative for gadolinium intoxication, which metals are bound by lipoic acid and why a slightly alkaline environment supports metal binding, even preventing the often-feared metal redistribution. All in all, this evidence-based chelation "cookbook" should be in medical libraries and on the bookshelf of every physician treating environmental disease.
