Book Synopsis Ruthenium Chemistry by : Ajay Kumar Mishra
Download or read book Ruthenium Chemistry written by Ajay Kumar Mishra and published by CRC Press. This book was released on 2018-01-17 with total page 260 pages. Available in PDF, EPUB and Kindle. 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.

Book Synopsis Electronic Structure of Ruthenium Complexes with Non-Innocent Ligands by : Amit Das
Download or read book Electronic Structure of Ruthenium Complexes with Non-Innocent Ligands written by Amit Das and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed valency in a ligand bridged homo-polynuclear complex arises when metal centers exist in their different oxidation states. The extent of intermetallic electronic coupling in the mixed valent state of polynuclear complex varies primarily depending on the nature of bridging and ancillary ligands as well as on the metal ion. On the other hand, the use of redox active (redox non-innocent) ligands in the complex framework creates ambiguities in the assignment of valence and spin configurations of such complexes as both the metal and ligand centers can take part in electron transfer processes. In consequence precise determination of valence and spin distributions in transition metal complexes comprising of redox non-innocent ligands is considered to be a formidable challenge. Thus, this book has been focused on how to overcome such problems through the correlation of experimental and theoretical results.

Book Synopsis Structure-activity Relationships of Ruthenium(II) Polypyridyl Complexes with Redox-active Intercalating Ligands by : Eugenia Soyo Narh
Download or read book Structure-activity Relationships of Ruthenium(II) Polypyridyl Complexes with Redox-active Intercalating Ligands written by Eugenia Soyo Narh and published by . This book was released on 2016 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The investigation and development of transition metal complexes as cancer chemotherapeutics has gained a lot of interest in the past few decades and has become a promising area of research. Metal complexes of platinum and ruthenium in particular that have demonstrated success as anticancer drugs or are under exploration currently for clinical use are highlighted in Chapter 1. Chapter 2 describes studies undertaken to understand the neurotoxicity of ruthenium(II) polypyridyl complexes (RPCs), including toxicity in mice and inhibition of the enzyme acetylcholinesterase (AChE), as previous work by Dwyer demonstrated that RPCs could be acutely toxic in mice, presumably due to their inhibition of AChE. Several ruthenium complexes were screened for their enzyme inhibitory potency which was correlated to their structural properties including size, charge, and lipophilicity. In addition, the inhibitory activity of the compounds was correlated to their animal toxicity data so as to understand the potential mode of action of the RPCs in vivo. Chapter 3 describes the synthesis of a series of novel ruthenium(II) polypyridyl complexes and their characterization. These complexes were prepared in an effort to tune the reduction potential of the redox-active intercalating ligand (RAIL) to potentials slightly above and below those observed for the Ru-tatpp complexes. The redox activity of ruthenium-tatpp complexes appears to be responsible for their DNA cleavage activity and these analogues, with slightly different reduction potentials, should give us additional insight into the activity of this class of RPCs. In Chapter 4, the electrochemical properties of the RPCs were measured and correlated with their ability to cause DNA cleavage under reducing conditions with GSH. Complexes with reduction potentials less (more positive) than the redox couple of GSH/GSSG were shown to efficiently cleave DNA. However complexes with higher reduction potentials than the biological reducing agent were not observed to cleave DNA under the same conditions. Cytotoxicity screening of these complexes in human non-small cell lung carcinoma cell lines (NSCLC -- H358 and HOP-62) and breast adenocarcinoma cell line (MCF-7), as well as the non-malignant cell line (MCF-10) was performed and described in Chapter 4.
Book Synopsis Controlling Redox Processes in Metal Complexes and Multifunctional Materials by : Khrystyna Herasymchuk
Download or read book Controlling Redox Processes in Metal Complexes and Multifunctional Materials written by Khrystyna Herasymchuk and published by . This book was released on 2020 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal complexes incorporating redox-active ligands have the potential to facilitate controlled multielectron chemistry, enabling their use in catalysis and energy storage applications. Moreover, the use of transition metal complexes containing redox-active ligands has been extended to two- (2D) and three-dimensional (3D) materials, such as supramolecular assemblies (i.e., metallacycles, molecular cages, or macrocycles) and metal-organic frameworks (MOFs) for catalytic, magnetic, electronic, and sensing applications. Salens (N2O2 bis(Schiff-base)-bis(phenolate) are an important class of redox-active ligands, and have been investigated in detail as they are able to stabilize both low and high metal oxidation states for the above-mentioned applications. The work in this thesis focuses on the synthesis and electronic structure elucidation of metal salen complexes in monomeric form, as discrete supramolecular assemblies and 3D MOFs. Structural and spectroscopic characterization of the neutral and oxidized species was completed using mass spectrometry, cyclic voltammetry, X-ray diffraction, NMR, UV-Vis-NIR, and EPR spectroscopies, as well as theoretical (DFT) calculations. Chapter 2 discusses the synthesis and electronic structure evaluation of a series of oxidized uranyl complexes, containing redox-active salen ligands with varying para-ring substituents (tBu, OMe, NMe2). Chapters 3 and 4 discuss the incorporation of a redox-active nickel salen complex equipped with pyridyl groups on the peripheral positions of the ligand framework into supramolecular structures via coordination-driven self-assembly. The self-assembly results in formation of a number of distinct metallacycles, affording di-, tetra-, and octa-ligand radical species. Finally, the design, synthesis, and incorporation of metal salen units into MOFs is discussed in Chapter 5. Preliminary assembly and oxidation experiments are presented as an opportunity to explore the redox-properties of salen complexes incorporated into a solid-state 3D framework. Overall, the work described in this thesis provides a pathway for salen ligand radical systems to be used in redox-controlled host-guest chemistry, catalysis, and sensing.

This book was released on 2012 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation describes the synthesis and reactivity of tantalum metal complexes containing a tridentate redox-active ligand. Fundamental studies have focused on utilizing the redox-active ligand to store multiple electron equivalents for oxidative addition and reductive elimination reactions. Chapter 1 provides an introduction to the characteristics of redox-active ligands and provides an overview of group transfer reactions involving redox-active ligands. The previous published results of bidentate redox-active ligands coordinated to Group IV d0 metals are discussed in terms of their decomposition side reactions. Chapter 2 describes the coordination of a known tridentate redox-active bis(phenoxy)amide ligand, (ONO), to a d0 tantalum(V) metal center and the examination of the redox properties of the resulting chloro oxidation products by electrochemical and spectroscopic methods. Chapter 3 examines the reactivity of the (ONO)TaR2 complexes in the general context of organometallic chemistry with a focus on protonolysis and reactivity with aryl azides, a known source of nitrene fragments upon oxidation. Chapter 4 examines the reactivity of the (ONO)TaX2 (X = Me, Cl) compounds with bulky diazoalkanes, a known carbene transfer reagent. The (ONO)TaCl2 complex proved to be a competent catalyst to generate cyclopropanes from styrene and the corresponding diazoalkane. Chapter 5 explores the utilization of the (ONO) ligand to store electron equivalents for the catalytic nitrene-nitrene coupling reactions with organoazides to afford organodiazenes. Finally, Chapter 6 addresses the electronic considerations of a related redox-active triamido ligand in an effort to tune the ligand's redox potentials.
