Book excerpt: Taken together the data presented in this review, and work by many other investigators, support the notion that DNA excision repair is important in a tumor cell's resistance to platinum compounds. Inhibition of this repair system by combination chemotherapy with the excision repair inhibitors HU and Ara-C produces synergistic cell kills and increased levels and persistance of DNA interstrand crosslinks. The studies with cis-DDP and ~-DDP in combination with UV induced thymine dimers suggest that there may be competition for DNA repair enzymes between the dimer and the platinum lesion. Whether the competing lesion is an intrastrand crosslink, interstrand crosslink, or platinum monoadduct (or all of these lesions) cannot be determined. The similarity between an intrastrand crosslink and a cyclobutane dimer suggests that these lesions may compete for repair. However, the increased peak levels of interstrand crosslinks, and increased persistence of these lesions at later time points suggest that this lesion may also be a substrate for the repair system. These observations may be of clinical relevance. Recently Dr. Kathy Albain of our institution has completed a Phase III I study using a 12 hour pretreatment with HU and Ara-C in patients prior to their cis-DDP therapy. She observed a significant number of responders in this trial (54). She is currently completing a second Phase IIII study substituting IV HU for the oral formulation. We anticipate initiating other clinical trials based upon these observations.

Book excerpt: The 7th International Symposium on Platinum and other metal coordination compounds in Cancer Chemotherapy, ISPCC '95, organized by the European Cancer Centre, was held in Amsterdam, the Netherlands, March 1-4, 1995. As with previous ISPCC meetings, the goal of ISPCC '95 was to bring together c1inicians, clinical investigators, scientists, and laboratory workers from many disciplines to promote further collaboration and cooperation in the development of new platinum and other metal coordination compounds as weil as in new ways to use 'c1assical' drugs as cisplatin and carboplatin in the treatment of cancer. Important aspects addressed by experts in the field inc1uded the synthesis and activity of new platinum compounds, the biochemistry and molecular pharrnacology as weil as the c1inical pharrnacology of this c1ass of antineoplastic agents, an overview of current c1inical studies, one special minisymposium on the mechanisms of cell kill of platinum, and one on resistance against platinum compounds. Finally, the current status of development of nonplatinum metal complexes was discussed. This volume contains the contributions of the various speakers at ISPCC '95 and provides an up-to-date and comprehensive overview of this important c1ass of anticancer agents, ranging from synthesis and molecular pharrnacology on one hand to c1inical pharrnacology and cIinical investigations on the other hand. The Organizing Corrunittee and Editors wish to express their gratitude to the contributors to this volume, to the various organizations and pharrnaceutical companies for their generous sponsoring of ISPCC '95, and to the Plenum Publishing Company for their help in producing this volume.

Book excerpt: It was a great pleasure and honour to have been invited to attend this Seminar and to present a final impression. The association in this field between the Chester Beatty Research Institute and Dr. Rosenberg's School at East Lansing is something which I specially value and many would doubtless like to know how it came about. In the course of its work in carcinogenesis and on chemotherapy over many years, the Chester Beatty Research Institute was frequently drawn to the importance of many metals - as for example lead, iron, metalloid arsenic and the metalloid quali ties of the carcinogenic hydrocarbons. Interest started in platinum many years ago, following the possibility, c1aimed by others, that various complexes between the metal and mercaptopurine might possess significant chemotherapeutic properties. Va rious attempts to confirm such findings ended, however, in complete failure. Interest in platinum was revived by the fresh observations of Dr. Rosenberg and his collea gues, and here the outcome was entirely different. Very soon it was possible to con firm the intense growth-inhibitory properties of cis-platinum (II) diamminedi chloride and related substances. After communicating these results to Dr. Rosenberg, it was a pleasure to welcome hirn in London where he gave a Seminar which greatly engaged the interest of many of the staff. Later, several of these were to enjoy Dr. Rosenberg's hospitality at an international conference on the subject to be held in East Lansing, where many rapidly developing aspects were open for discussion.

This book was released on 2012-12-06 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for convening a Fourth International Symposium on Platinum Coordination Complexes in Cancer Chemotherapy was born in an assembly of researchers from the Vermont Regional Cancer Center and the Norris Cotton Cancer Center who shared a common interest in metal complexes. It was agreed by those assembled that sufficient time had passed since the Third International Symposium on Platinum Coor dination Complexes in Cancer Chemotherapy held in 1976 at the Wadley Institutes of Molecular Medicine in Dallas, Texas, during which several advances in the chemistry, biochemistry, pharmacology and clinical use of platinum complexes had occurred, to warrant a fourth symposium. Furthermore, intensive investigations in progress were bringing sophisticated methodologies to bear on the problems in the field, clinical trials were yielding interesting results, and unique approaches to cancer therapy were being designed. Therefore, an organizing committee was formed and planning culminated in the symposium which was held in Burlington, Vermont, June 22-24, 1983.

This book was released on 2007-08-07 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photochemistry (a term that broadly speaking includes photophysics) is abranchofmodernsciencethatdealswiththeinteractionoflightwithmatter and lies at the crossroadsof chemistry, physics, and biology. However, before being a branch of modern science, photochemistry was (and still is today), an extremely important natural phenomenon. When God said: “Let there be light”, photochemistry began to operate, helping God to create the world as wenowknowit.Itislikelythatphotochemistrywasthesparkfortheoriginof life on Earth and played a fundamental role in the evolution of life. Through the photosynthetic process that takes place in green plants, photochemistry is responsible for the maintenance of all living organisms. In the geological past photochemistry caused the accumulation of the deposits of coal, oil, and naturalgasthat wenowuseasfuels.Photochemistryisinvolved inthecontrol ofozoneinthestratosphereandinagreatnumber ofenvironmentalprocesses thatoccurintheatmosphere,inthesea,andonthesoil.Photochemistryisthe essenceoftheprocessofvisionandcausesavarietyofbehavioralresponsesin living organisms. Photochemistry as a science is quite young; we only need to go back less than one century to ?nd its early pioneer [1]. The concept of coordination compound is also relatively young; it was established in 1892, when Alfred Werner conceived his theory of metal complexes [2]. Since then, the terms coordination compound and metal complex have been used as synonyms, even if in the last 30 years, coordination chemistry has extended its scope to the binding ofall kinds of substrates [3, 4].

This book was released on 2009-01-09 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cisplatin, the first member of the family of platinum-containing chemotherapeutic agents, was discovered by Barnett Rosenberg in 1965 and approved by the FDA for marketing in 1978. After 30 years of use in the clinic, cisplatin remains a central element of many treatment regimens. Cisplatin is still an irreplaceable component of a regimen that produces high cure rates in even advanced nonseminomatous germ-cell cancers, and is widely used in the treatment of ovarian cancers and other gynecologic cancers, head and neck, and numerous other tumor types. The development of carboplatin has reduced some of the adverse events associated with cisplatin treatment, and the introduction of the DACH platinum compound oxaliplatin has broadened the spectrum of activity of the platinums to include gastro-intestinal cancers, especially colorectal cancer. The clinical importance of this family of drugs continues to drive investigation into how these drugs work and how to improve their efficacy and reduce their toxicity. The papers in this volume were presented in Verona, Italy, during the tenth International Symposium on Platinum Coordination Compounds in Cancer Chemotherapy. The symposium was jointly organized by the Department of Oncology of the Mater Salutis Hospital – Azienda Sanitaria Locale 21 of the Veneto Region – and by the Department of Medicine and Public Health, Section of Pharmacology, the University of Verona. They reflect the vitality of this field and the increasing use of new molecular and cell biologic, genetic, and biochemical tools to identify approaches to further improve their use.

This book was released on 2018-02-05 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 18, entitled Metallo-Drugs: Development and Action of Anticancer Agents of the series Metal Ions in Life Sciences centers on biological, medicinal inorganic chemistry. The serendipitous discovery of the antitumor activity of cis-diamminodichloroplatinum(II) (cisplatin) by Barnett Rosenberg in the 1960s is a landmark in metallodrug-based chemotherapy. The success of cisplatin in the clinic, followed by oxaliplatin and carboplatin, along with their drawbacks relating mainly to resistance development and severe toxicity, initiated research on polynuclear platinum complexes and on Pt(IV) complexes as prodrugs. Furthermore, the indicated shortcomings led to the exploration of other transition and main group metal ions, among them Ru(II/III), Au(I/III), Ti(IV), V(IV/V), and Ga(III) including also the essential metal ions Fe(II/III), Cu(I/II), and Zn(II). Ionic as well as covalent and non-covalent interactions between structurally very different complexes and biomolecules like nucleic acids, proteins, and carbohydrates are studied and discussed with regard to their possible anticancer actions. Hence, MILS-18 summarizes the research at the forefront of medicinal inorganic chemistry, including studies on the next-generation, tailor-made anticancer drugs. All this and more is treated in an authoritative and timely manner in the 17 stimulating chapters of this book, written by 39 internationally recognized experts from 10 nations (from the US via Europe to China and Australia). The impact of this vibrant research area is manifested by more than 2700 references, nearly 150 illustrations (more than half in color) and several comprehensive tables. Metallo-Drugs: Development and Action of Anticancer Agents is an essential resource for scientists working in the wide range from enzymology, material sciences, analytical, organic, and inorganic biochemistry all the way through to medicine including the clinic ... not forgetting that it also provides excellent information for teaching.

Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of platinum group metals is a rapidly expanding commercially important field. It is dominated by the catalytic properties of the metals. They are useful in petrochemical and general chemical plants and are becoming increasingly important as autocatalysts for pollution control. The book covers recent developments in the chemistry of the six platinum group metals, namely, platinum, palladium, rhodium, iridium, ruthenium and osmium. The material falls into three broad areas. Firstly, the occurrence, extraction and use of the metals, especially in catalysis, electrochemistry, energy and electronics. Secondly, organometallic and homogeneous catalytic chemistry and last but not least coordination chemistry including biochemistry and cancer therapy. The work is aimed at scientists in universities and in industry using any of the six platinum group metals in research. It will be useful for those studying the compounds of the metals themselves, and those considering to use either the metals or their complexes and catalysts in their experimental work.
