Book excerpt: 30 years after its discovery as an antitumor agent, cisplatin represents today one of the most successful drugs in chemotherapy. This book is intended to reminisce this event, to take inventory, and to point out new lines of development in this field. Divided in 6 sections and 22 chapters, the book provides an up-to-date account on topics such as - the chemistry and biochemistry of cisplatin, - the clinical status of Pt anticancer drugs, - the impact of cisplatin on inorganic and coordination chemistry, - new developments in drug design, testing and delivery. It also includes a chapter describing the historical development of the discovery of cisplatin. The ultimate question - How does cisplatin kill a cell? - is yet to be answered, but there are now new links suggesting how Pt binding to DNA may trigger a cascade of cellular reactions that eventually result in apoptosis. p53 and a series of damage recognition proteins of the HMG-domain family appear to be involved. The book addresses the problem of mutagenicity of Pt drugs and raises the question of the possible relevance of the minor DNA adducts, e.g. of interstrand cross-links, and the possible use of trans-(NH3)2Pt(II)-modified oligonucleotides in antisense and antigene strategies. Our present understanding of reactions of cisplatin with DNA is based upon numerous model studies (from isolated model nucleobases to short DNA fragments) and application of a large body of spectroscopic and other physico-chemical techniques. Thanks to these efforts there is presently no other metal ion whose reactions with nucleic acids are better understood than Pt. In a series of chapters, basic studies on the interactions of Pt electrophiles with nucleobases, oligonucleotides, DNA, amino acids, peptides and proteins are reported, which use, among others, sophisticated NMR techniques or X-ray crystallography, to get remarkable understanding of details on such reactions. Reactivity of cisplatin, once bound to DNA and formerly believed to be inert enough to stay, is an emerging phenomenon. It has (not yet) widely been studied but is potentially extremely important. Medicinal bioinorganic chemistry - the role of metal compounds in medicine - has received an enormous boost from cisplatin, and so has bioinorganic chemistry as a whole. There is hardly a better example than cisplatin to demonstrate what bioinorganic chemistry is all about: The marriage between classic inorganic (coordination) chemistry and the other life sciences - medicine, pharmacy, biology, biochemistry. Cisplatin has left its mark also on areas that are generally considered largely inorganic. The subject of mixed-valance Pt compounds is an example: From the sleeping beauty it made its way to the headlines of scientific journals, thanks to a class of novel Pt antitumor agents, the so-called "platinum pyrimidine blues". In the aftermath diplatinum (III) compounds were recognized and studies in large numbers, and now an organometalic chemistry of these diplatinum (III) species is beginning to emerge. The final section of the book is concerned with new developments such as novel di- and trinuclear Pt(II) drugs with DNA binding properties different from those of cisplatin, with orally active Pt(IV) drugs which are presently in clinical studies, and with attempts to modify combinatorial chemistry in such a way that it may become applicable to fast screening of Pt antitumor drugs. The potential of including computational methods in solving questions of Pt-DNA interactions is critically dealt with in the concluding chapter.

This book was released on 2011-05-19 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: Olefin Upgrading Catalysis by Nitrogen-based Metal Complexes II: State-of-the-art and Perspectives provides a critical review of the state-of-the-art developments in industrially relevant processes connected to efficient and selective olefin upgrading. Specific attention is devoted to catalysts containing imine- and amine-based ligands. All the chapters in this book have been designed to provide a systematic account of the vast amount of information available for this type of catalyst as well as to highlight the factors that ultimately control the catalyst’s performance and productivity. A comprehensive panorama of catalyst precursors is presented, spanning from group 10 α-diimine complexes and iron and cobalt 2,6-bis(imino)pyridine derivatives, to vanadium, chromium, titanium, zirconium and lanthanide complexes supported by nitrogen-containing ligands. The authors of this collective work are currently involved in the development of imine-based catalysts for efficient and selective olefin upgrading and the majority of them have dedicated most of their scientific career to this important field. In writing this book, their major goal is to transfer as many ideas and experiences as possible to the global audience of scientists engaged in this area of research.

Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of cisplatin as a potent anticancer agent, transition metal complexes have played a significant role in the development of new anticancer compounds. The anticancer potential of cobalt complexes has been extensively studied over the last three decades, and much time has been devoted to understanding their mechanisms of action. After understanding the Co(III)/Co(II) reduction activation mechanism, several Co(III) complexes of bioactive anticancer agents have been investigated as potential hypoxia activated prodrugs. Furthermore, after the initial use of nitrogen mustard, several bioactive compounds and their analogues have been investigated as ligands to develop hypoxia activated Co(III) complexes. This thesis describes syntheses and characterisation of Co(III) complexes that have been designed using structural analogues of bioactive anticancer compounds. Chapter 1 gives an overview of the prodrug strategy in cancer therapy, prodrug design using a trigger and an effector unit, and different mechanisms for prodrug activation. Several examples of Co(III) complexes are given, which have been investigated as potential prodrugs to target tumour hypoxia. There are three different parts to this research. Chapters 2, 3 and 4 describe the syntheses and characterisation of Co(III) complexes designed using ligands, which are structural analogues of bioactive anticancer compounds. Chapter 2 describes syntheses of dipeptide analogues of bortezomib, a proteasome inhibitor that is currently being used for the treatment for multiple myeloma. The Co(III)-dipeptide complexes were also analysed for their possible use as hypoxia activated prodrugs in Chapter 2. Chapter 3 includes the continuation to the previous investigation by Ware et al. on Co(III)-cyclen complex using 8-hydroxyquinoline (8HQ) as a model cytotoxin. Efforts were made to establish a synthetic route to introduce a porphyrin derivative into prodrug design, with the aim of improving tumour cell targeting properties of the prodrug complex. Chapter 4 describes syntheses of two polypyridyl carboxamide ligands, PDPA and MID(AMP)2, and syntheses of their Co(III) complexes. PDPA and MID(AMP)2, are structural analogues of PMAH, Py3PH2, which are carboxamide ligands containing a similar metal-binding domain as bleomycins. The experimental procedures are detailed in Chapter 5.

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.

This book was released on 2010-07-28 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reaction of transition metal ions with ditopic ligands containing two 2,2':6',2"-terpyridine units linked by flexible spacers can give metallosupramolecular polymers, discrete metallomacrocycles or mixtures of the two. The outcome of the coordination depends on the precise reaction conditions as well as the nature of the spacer and the transition metal salt. This thesis is concerned with the reaction between cobalt(II) salts and bis(2,2':6',2"-terpyridine) ligands in which the metal-binding domains are linked by flexible oligo(ethylene glycol) spacers. An initial study of the ligands and several model mononuclear bis(2,2':6',2"-terpyridine)cobalt(II) and (III) complexes gave some insight into the solid state and solution properties of these systems, and PGSE NMR spectroscopy was found to be a useful tool for determination of the size of both the ligands and the cobalt(III) complexes in solution. The reaction of the ditopic ligands with cobalt(II) acetate tetrahydrate in pure alcohol was found to cause the decomposition of the ligand and the formation of a mononuclear bis(4'-alkoxy-2,2':6',2"-terpyridine)cobalt(II) complex. This reaction was extended to monotopic 4'-substituted-2,2':6',2"-terpyridines and can be considered as a reaction giving rise to polymer end-capping units, thus influencing the final outcome of the coordination. The effect of the anion on the coordination was considered further, and the speciation of mono- and bis(2,2':6',2"-terpyridine)cobalt(II) complexes in solution was investigated using the 4'-methoxy-2,2':6',2"-terpyridine ligand. The product mixtures were found to depend heavily on the anion, solvent and initial ratio of ligand to metal salt. Similar behaviour was observed for a model ditopic ligand. The presence of the mono(2,2':6',2"-terpyridine)cobalt(II) complexes within a system containing the ditopic ligands would also provide polymer end-capping units, influencing the speciation of these mixtures. Finally, a detailed study of the product mixtures obtained from the reactions of the ditopic ligands with cobalt(II) salts revealed a complex dependence of the speciation of many bis(2,2':6',2"-terpyridine)cobalt(II) complexes on the ligand, anion, solvent, concentration and other seemingly minor reaction parameters. Using the PGSE NMR spectroscopic technique, the sizes of some of the metallomacrocyclic species present in the equilibrium mixtures could be determined. These measurements were in excellent agreement with X-ray crystallographic data. Analysis of initial product mixtures using the same technique suggested that the initial kinetic products of the complexation are significantly larger species.
