Book excerpt: This book will describe Ruthenium complexes as chemotherapeutic agent specifically at tumor site. It has been the most challenging task in the area of cancer therapy. Nanoparticles are now emerging as the most effective alternative to traditional chemotherapeutic approach. Nanoparticles have been shown to be useful in this respect. However, in view of organ system complicacies, instead of using nanoparticles as a delivery tool, it will be more appropriate to synthesize a drug of nanoparticle size that can use blood transport mechanism to reach the tumor site and regress cancer. Due to less toxicity and effective bio-distribution, ruthenium (Ru) complexes are of much current interest. Additionally, lumiscent Ru-complexes can be synthesized in nanoparticle size and can be directly traced at tissue level. The book will contain the synthesis, characterization, and applications of various Ruthenium complexes as chemotherapeutic agents. The book will also cover the introduction to chemotherapy, classification of Ru- complexes with respect to their oxidation states and geometry, Ruthenium complexes of nano size: shape and binding- selectivity, binding of ruthenium complexes with DNA, DNA cleavage studies and cytotoxicity. The present book will be more beneficial to researchers, scientists and biomedical. Current book will empower specially to younger generation to create a new world of ruthenium chemistry in material science as well as in medicines. This book will be also beneficial to national/international research laboratories, and academia with interest in the area of coordination chemistry more especially to the Ruthenium compounds and its applications.

The recent advances in research on platinum, ruthenium and gold complexes have received much attention in medicinal chemistry, and studies of other less explored metal complexes may reveal alternative mode of mechanism as novel therapeutic agents. A series of dirhodium(II, II) complexes with carboxylate and carboxamidate ligands and thiourea complexes of coinage metals have been prepared in this study. Their biological activities and mechanisms of action have been studied. Dirhodium(II, II) carboxylate complexes with variations of alkyl and benzoyl side chains were synthesized and displayed remarkable cytotoxicities to cancer cells with potency down to submicromolar level. The cytotoxicities of rhodium complexes were found to significantly correlate with the cellular uptake of the rhodium complexes. As revealed by oligonucleotide microarray and bioinformatic analysis, the mode of action of the rhodium carboxylate complexes are highly similar to that of a proteasome inhibitor. Further cellular and biochemical studies showed that rhodium carboxylate complexes induced an accumulation of ubiquitinated proteins, inhibited the proteolytic activities of purified 20S proteasome and proteasomal deubiquitinating enzyme. These results corroborate that the impairment of the ubiquitin-proteasome system is linked to the cytotoxic action of rhodium carboxylate complexes. Silver is known to be an anti-inflammatory agent for topical treatment. A silver complex of N, N''-disubstituted cyclic thiourea that is reasonably stable towards reduced glutathionewas found to potently inhibit the NF-B transcriptional activity. Treatment of cells with silver thiourea inhibited TNF-α-stimulated IκB kinase activity, IκBα phosphorylation and degradation, nuclear translocation of NF-κB p65 and eventually the stimulated gene expression of inflammatory cytokines. Suppression of IκB kinase activity was associated with modification of sensitive cysteine residues and disruption of IκB kinase assembly. These data demonstrated that the inhibitory properties of Ag+ ions on an anti-inflammatory and anti-cancer drug target could be effectively delivered via the thiourea ligand. Silver is also an antimicrobial metal, and this study was also extended to understand the silver-bacteria interaction using a silver resistant bacteria as a model. Many silver resistant bacteria often produce considerable amount of silver particles when exposed to high concentrations of silver salts but the mechanism of biosynthesis is not well understood. A silver resistant E. coli that displays active silver efflux was shown to synthesize zero-valent silver nanoparticles in the periplasmic space through reduction of silver ions under anaerobic conditions. As the microbial c-type cytochromes are known to mediate respiratory metal reduction, their role in the biosynthesis of silver nanoparticles was examined. A deletion mutant of the cytoplasmic membrane-anchored tetra-heme c-type cytochrome subunit of periplasmic nitrate reductase (NapC) showed marked reduction of accumulation of silver nanoparticles. This study identified a molecular mechanism of biosynthesis of silver nanoparticles that may have implication in bioenvironmental pro

Available in PDF, EPUB and Kindle. Book excerpt: Metal-based anticancer drugs are among the most successful therapeutic agents, as evidenced by the frequent prescription of selected platinum and arsenic compounds to patients. Metal-based Anticancer Agents covers the interdisciplinary world of inorganic drug discovery and development by introducing the most prominent compound classes based on different transition metals, discussing emerging concepts and enabling methods, as well as presenting key pre-clinical and clinical aspects. Recent progress on the unique features of next-generation targeted metal-based anticancer agents, including supramolecular coordination complexes used for both therapy and drug delivery, promise a bright future beyond the benefits of pure cytotoxic activity. With contributions from global leaders in the field, this book will serve as a useful reference to established researchers as well as a practical guide to those new to metallodrugs, and postgraduate students of medicinal chemistry and metallobiology.
