Book Description
One of the central problems in the study of the mechanism of DNA-ligand interactions is the existence and nature of sequence specificity with respect to the base pairs of DNA. The presence of such a specificity could be of particular significance because it might possibly mean the involvement of specific genes in the effectiveness of the different drugs. The elucidation of the factors responsible for the specificity could then be important for the development of compounds susceptible to contribute to the control of gene expression and also to the development of rationally conceived, improved new generations of effective and specific chemotherapeutic agents. Important recent achievements, experimental and theoretical, in the analysis of such sequence specificities open prospects for possible rapid progress in this field. The 23rd Jerusalem symposium was devoted to the exploration of these recent achievements in relation to many types of ligand, with special emphasis on antitumor drugs. All major types of interaction, intercalation, groove binding, covalent linking, coordination, have been considered. So was also the effect of the interaction on the structure and properties of the nucleic acids and the relationship between the interaction and biological or pharmacological activities. We feel that this Volume presents a relatively complete up-to-date account of the state of the art in this important field of research.

Book Description
The development of molecules that selectively bind to nucleic acids has provided many details about DNA and RNA recognition. The range of such substances, such as metal complexes, peptides, oligonucleotides and a wide array of synthetic organic compounds, is as manifold as the functions of nucleic acids. Nucleic acid recognition sequences are often found in the major or minor groove of a double strand, while other typical interactions include intercalation between base pairs or the formation of triple or quadruple helices. One example of a binding mode that has recently been proposed is end stacking on such complex structures as the telomere tetraplex. In this comprehensive book, internationally recognized experts describe in detail the important aspects of nucleic acid binding, and in so doing present impressive approaches to drug design. Since typical substances may be created naturally or synthetically, emphasis is placed on natural products, chemical synthesis, the use of combinatorial libraries, and structural characterization. The whole is rounded off by contributions on molecular modeling, as well as investigations into the way in which any given drug interacts with its nucleic acid recognition site.

Book Description
Metal ions and metal complexes have long been recognized ascritically important components of nucleic acid chemistry, both inregulation of gene expression and as promising therapeutic agents.Understanding how metal complexes interact with DNA has become anactive research area at the interface between chemistry, molecularbiology and medicine. Metal Complex - DNA Interactions provides a comprehensiveoverview of this increasingly diverse field, presenting recentdevelopments and the latest research with particular emphasis onmetal-based drugs and metal ion toxicity. The text is divided intofour parts: Basic Structural and Kinetic Aspects: includes chapterson sequence-selective metal binding to DNA and thermodynamicmodels. Medical Applications: focuses on anticancer platinumdrugs, including discussions on DNA repair in antitumor effects ofplatinum drugs and photo-dynamic therapy. DNA-Recognition - Nucleases and Sensor: describesprobes for DNA recognition, artificial restriction agents,metallo-DNAzymes for metal sensing applications and metal iondependent catalysis in nucleic acid enzymes. Toxicological Aspects: deals with structural studies ofmercury–DNA interactions, chromium-induced DNA damage andrepair, and the effect of arsenic and nickel on DNAintegrity. This book will be a valuable resource for academic researchersand professionals from a range of pharmaceutical and chemicalindustries, particularly those involved in the development of newand less toxic anticancer metallo-drugs, and in the field ofenvironmental and toxicological chemistry.

Book Description
DNA sequence specificity is a sub-specialty in the general area of molecular recognition. This area includes macromolecular-molecular interactions (e.g., protein-DNA), oligomer-DNA interacitons (e.g., triple strands), and ligand-DNA interactions (e.g., drug-DNA). It is this latter group of DNA sequence specificity interactions that is the subject of Volumes 1 and 2 of Advances in DNA Sequence Specific Agents. As was the case for Volume 1, Part A also covers methodology, but in Volume 2 we include calorimetric titrations, molecular modeling, X-ray crystallographic and NMR structural studies, and transcriptional assays. Part B also follows the same format as Volume 1 and describes the sequence specificities and covalent and noncovalent interactions of small ligands with DNA.This volume is aimed in general at scientists who have an interest in deciphering the molecular mechanisms for sequence recognition of DNA. The methods have general applicability to small molecules as well as oligomers and proteins, while the examples provide general principles involved in sequence recognition.

Book Description
There have been remarkable advances towards discovering agents that exhibit selectivity and sequence-specificity for DNA, as well as understanding the interactions that underlie its propensity to bind molecules. This progress has important applications in many areas of biotechnology and medicine, notably in cancer treatment as well as in future gene targeting therapies. The editor and contributing authors are leaders in their fields and provide useful perspectives from diverse and interdisciplinary backgrounds on the current status of this broad area. The role played by chemistry is a unifying theme. Early chapters cover methodologies to evaluate DNA-interactive agents and then the book provides examples of DNA-interactive molecules and technologies in development as therapeutic agents. DNA-binding metal complexes, peptide and polyamide–DNA interactions, and gene targeting tools are some of the most compelling topics treated in depth. This book will be a valuable resource for postgraduate students and researchers in chemical biology, biochemistry, structural biology and medicinal fields. It will also be of interest to supramolecular chemists and biophysicists.

Book Description
In this volume the entire focus is devoted to the macromolecule target specificity of DNA interactive developmental therapeutic agents of current interest. A brief introduction to DNA interactive anticancer agents is included for readers who may benefit from an overview surrounding the developments that have contributed to our general understanding of this field. The following nine chapters have been carefully chosen so that they describe topics which are at the forefront of development in DNA-targeted cancer chemotherapy. Issues that have been addressed include the mechanisms of selective DNA topoisomerase I and II poisoning by antitumor agents (Chapters 1 and 2), sequence-specific recognition of DNA by groove-binding drugs and drug-conjugates (Chapters 3 and 4), recent developments in nitrogen mustard alkylating agents and their potential use for antibody-directed enzyme-prodrug therapy (Chapter 5), nonclassical platinum anticancer complexes, including dinuclear and trans-platinum derivatives (Chapter 6), DNA cleaving antitumor chromoproteins containing reactive enediyne moieties, which exhibit interesting free-radical chemistry along with selective targeting (Chapter 7), the potential of new sequence-specific antisense and antigene therapy in oncology (Chapter 8), and finally the conceivable chemotherapeutic use of mimetics of the DNA structure, obtained by substitution of the sugar-phosphate natural chain with a peptide backbone, the so-called peptide nucleic acids (Chapter 9). Important approaches being currently investigated for selective cancer treatment, such as gene therapy and immunochemotherapy, are not discussed in this volume since they fall beyond its scope.
