Dna Interactions With Drugs And Other Ligands

DNA Interactions With Drugs and Other Small Ligands: Single Molecule Approaches and Techniques provides the reader with all the main information, a "state-of-the-art" of sorts and an overall review of the field. There is no other book currently available that covers all these subjects together. On the contrary, the different subjects that are developed in this book are currently scattered in journal articles and other books. Presents a review of the fundamental knowledge, techniques and relevant information surrounding the field of DNA interactions with drugs and other ligands Provides a resource like no other book available Includes valuable information from the author who is a highly experienced researcher in the field

This volume contains the texts of the nineteen lectures presented at the NATO-ASI - FEBS Course on "DNA - ligand interactions: from drugs to proteins." The Advanced Study Institute (ASIl was held from August 30th to September 11th. 1986 in the Abbey of Fontevraud (France). The ASI was attended by 112 participants from a wide scientific horizon and from twentyone different countries. It was in some way a follow-up of the ASI held in Maratea. Italy in May 1981 and which was published in the NATO ASI Life Science series as volume 45. While much has been learned about the way the cellular machinery maintains and transmits the genetic heritage. as well as how these processes are regulated. little is Known about how the interactions between the various partners involved are taKing place. The interactions of drugs and proteins with nucleic acids are of evident importance in the understanding of these problems. The spectacular advances in recombinant DNA technology and the increased sophistication of biophysical techniques. in particular >:-ray diffraction and nuclear magnetic resonance. have created a scientific environment which is highly promising for the future of research in molecular biology. These advances permH the serious hope that biology on the molecular level may become a r-eality. Some of the contributions at the ASI presented the most recent advances in this e>:citing field.

A collection of useful molecular techniques to illuminate and explore the interaction of drugs and ligands with DNA. These easily reproducible methods involve sequence recognition properties, as well as the physical approaches for measuring both the strength of interaction and the mode of drug binding to DNA. The interactions are also examined from a cellular perspective and for their usefulness in the design of new therapeutic agents. The powerful techniques detailed here will be particularly useful in elucidating the action of existing therapeutic agents, as well as in the design of new anti-cancer drugs with improved action and reduced toxicity.

This volume consolidates the key methods for studying ligand-nucleic acid interactions into a convenient source. Techniques that are examined range from biophysical and chemical approaches to methods rooted in molecular and cell biology.

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.

Since most therapeutic efforts have been predominantly focused on pharmaceuticals that target proteins, there is an unmet need to develop drugs that intercept cellular pathways that critically involve nucleic acids. Progress in the discovery of nucleic acid binding drugs naturally relies on the availability of analytical methods that assess the efficacy and nature of interactions between nucleic acids and their putative ligands. This progress can benefit tremendously from new methods that probe nucleic acid/ligand interactions both rapidly and quantitatively. A variety of novel methods for these studies have emerged in recent years, and Methods for Studying DNA/Drug Interactions highlights new and non-conventional methods for exploring nucleic acid/ligand interactions. Designed to present drug-developing companies with a survey of possible future techniques, the book compares their drawbacks and advantages with respect to commonly used tools. Perhaps more importantly, this book was written to inspire young scientists to continue to advance these methods into fruition, especially in light of current capabilities for assay miniaturization and enhanced sensitivity using microfluidics and nanomaterials.

In this authoritative book, experts in the field highlight the main principles and methodologies currently utilized in the study of molecular interactions between compounds. This is as an ideal guide to those striving to further our knowledge of medicines.
