Estatisticas da Organizacao Mundial de Saude (WHO) apontam o cancer como uma das maiores causas de morte em todo o mundo. Estima-se que o numero de mortes aumente em 45% entre 2007 e 2030. Celulas em hipoxia tem sido responsaveis pelas desvantagens apresentadas nos tratamentos terapeuticos em combate ao cancer, uma vez que a radioterapia e alguns agentes quimioterapicos precisam de oxigenio molecular para apresentar atividade citotoxica. Por isso, sao estudadas novas substancias para atuarem como pro-drogas ativadas por hipoxia (PDHAs). Complexos de Co(III) sao estudados como possiveis PDHAs...

Herr Hermann Sicius bringt dem Leser in knapper Form alle wichtigen Informationen rund um die Halogene nahe, die eine der chemisch reaktivsten Gruppen von Elementen sind. Die Halogene sind teils schon lange bekannt, werden in sehr vielen Anwendungen eingesetzt und zeigen eine vor allem hinsichtlich ihrer Verbindungen mit anderen Nichtmetallen sehr interessante Chemie. Fluor und Chlor sind bei Raumtemperatur Gase, Brom ist neben Quecksilber das einzige unter diesen Bedingungen flussige Element, wogegen Iod, Astat und moglicherweise auch Ununseptium unter diesen Bedingungen Feststoffe sind....

En fait, la mA(c)thode hydrothermale reprA(c)sente une voie chimique favorable A l'A(c)laboration des nanomatA(c)riaux. Cette technique fait intervenir une phase liquide qui facilite la diffusion des espA]ces chimiques et permet d'obtenir, A des...

Dieses Essential gibt Ihnen eine kompakte, aber umfassende Ubersicht uber die Pnictogene, diese vielseitigen Elemente, die in zahlreichen Oxidationsstufen auftreten konnen und deren Charakter von nichtmetallisch (Stickstoff, teilweise auch Phosphor) uber halbmetallisch (Arsen, Antimon) bis metallisch (Bismut und Ununpentium) reicht. Es gibt zahlreiche Anwendungen, von denen hier uber die Wichtigsten berichtet wird. Die Kenntnis uber einige der Elemente reicht schon weit zuruck: Antimon ist seit einigen tausend Jahren bekannt, Arsen seit etwa 800, Phosphor seit 350 und Stickstoff und Bismut...

This multi-author edited volume reviews the recent developments in boron chemistry, with a particular emphasis on the contribution of computational chemistry. The contributors come from Europe, the USA and Asia. About 60% of the book concentrates on theoretical and computational themes whilst 40% is on topics of interest to experimental chemists. Specific themes covered include structure, topology, modelling and prediction, the role of boron clusters in synthetic chemistry and catalysis, as medical agents when acting as inhibitors of HIV protease and carbonic anhydrases.

Bioinorganic chemistry is a field that examines the role of metals in biology. Bioinorganic chemistry includes the study of both natural phenomena such as the behavior of metalloproteins as well as artificially introduced metals, including those that are non-essential, in medicine and toxicology. Many biological processes such as respiration depend upon molecules that fall within the realm of inorganic chemistry. The discipline also includes the study of inorganic models or mimics that imitate the behaviour of metalloproteins. As a mix of biochemistry and inorganic chemistry, bioinorganic...

Drug discovery is a vast area of research due to increase in bacterial and fungal resistance against available drugs. This book will give the basic concepts of Schiff-Mannich Base derivatives of Benzimidazole, Metal complexes and their application in the field of drug discovery. It will also provide the basic mechanistic study as well as the knowledge about characterization techniques which will be helpful for young students and researchers to have a deep insight about Antibacterial and Antifungal agents.

L'A(c)tude des nanomatA(c)riaux et de leurs propriA(c)tA(c)s fait appel A plusieurs disciplines (physique, chimie, biologie, mA(c)decine, ...). Dans le domaine de la science des matA(c)riaux, beaucoup de familles sont concernA(c)es par cette A(c)tude: les mA(c)taux, les alliages semi-conducteurs du groupe IV et III-V, les oxydes, ... Quoique, les semi-conducteurs nanomA(c)triques sont les plus dA(c)sirA(c)s A cause de leurs propriA(c)tA(c)s A(c)lectroniques et optiques intA(c)ressantes. En effet, la taille rA(c)duite des cristallites semi-conductrices induit une augmentation des niveaux...

This book describes structural and catalytic roles of metal ions in RNA in an authoritative and timely manner. It deals with diffuse metal ion binding, RNA quadruplexes, the regulation of riboswitches, metal ions and ribozymes, including artificial ribozymes. The spliceosome, the ribosome, ribozymes involving redox cofactors as well as the binding of kinetically inert metal ions to RNA are also covered.

The occurrence of a wide variety of metal-carbon bonds in living organisms, ranging from bacteria to humans, is only recently appreciated. Of course, the historical examples are the B12 coenzymes containing cobalt-carbon bonds, but now such bonds are also known for nickel, iron, copper, and other transition metal ions. MILS-6, written by 20 experts, summarizes the most recent insights into this fascinating topic.

These sulfur-rich chelators, being important in metal ion homeostasis, find increasing attention. MILS-5, written by 30 internationally recognized experts, focuses on this hot topic. This book is an essential resource for scientists working in the wide range from environmental toxicology and inorganic biochemistry all the way through to physiology and medicine.
