Molecular Basis of Specificity in Nucleic Acid-Drug Interactions


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.







Comprehensive Natural Products Chemistry: DNA and aspects of molecular biology


Book Description

Hardbound. This volume is intended to cover the chemistry of one of the most widely studied and important natural products, DNA. Discussed in detail are physicochemical properties of the molecule itself as well as small-molecule natural products that are known to interact with it. Also included are methods to synthesize and manipulate DNA and modified analogues. Twenty chapters are devoted to this overall topic.The first five relate to the structure of DNA; the first focuses on thermodynamics and kinetics of double helix formation; the next two describe triple- and tetra- helical structures formed by DNA; and the last two focus on methods for probing DNA structure (specifically, NMR methods and chemical probing methods, respectively).Chapters 6-12 focus on the chemistry of natural DNA and modified analogues. The first of these addresses nonenzymatic methods for synthesizing DNA, and the next chapter, on methods for attachment of reporter groups t







Host-Guest Molecular Interactions


Book Description

Composed of contributions from experts in the chemical and biological sciences, it explores host-guest molecular interactions leading to the formation of molecular assemblies containing two or more species. Exciting applications are emerging in this field and it is expected that improved understanding of the interactions in synthetic host molecule complexes will lead to a better understanding of the more complex biological systems. Topics include biomimetic chemistry, preorganization, self-assembly, template-directed synthesis, antibiotic binding to peptides and DNA, interactions between proteins and other molecules.







Molecular Aspects of Anticancer Drug DNA Interaction


Book Description

This cutting-edge book surveys the current knowledge on the mode of action of the major classes of DNA-interactive antitumor agents, providing information that could be crucial for the discovery of new therapeutic substances. It is an important reference for molecular biologists, cancer researchers, biochemists, biophysicists, and pharmacologists.




Anthracycline Antibiotics


Book Description

Developed from a symposium at the 205th National Meeting of the ACS in Denver, March 1993, held to bring together researchers who are involved in the direct design and synthesis of new drugs with researchers who are investigating biochemical processes and mechanisms of action. The volume covers research relevant to the development of novel anthracyclines, such as the synthesis of promising new analogs, studies of mechanisms of action, and new approaches to improving properties for this class of compounds by using different drug- delivery and tumor-targeting systems.

The Search for New Anticancer Drugs


Book Description

Most of the anti-cancer drugs in use today were discovered by happy accident rather than design, yet the rational design of better anti-cancer drugs remains a cherished goal, and one of the most important challenges facing medical science. This book represents a compilation of views and progress reports which illustrate the diversity of approaches to the problem. Recent research has confirmed the belief that critical genetic changes are at work in cancer cells. The genome, then (DNA in biochemical terms), surely represents a critical target for specific chemotherapy of cancer, and several chapters address the issue of attacking DNA, gene targetting, and the like. Others deal with principles of rational design, exploitation of novel modalities and targets, or the nuts and bolts of antitumour drug testing. While no attempt has been made to provide a comprehensive coverage of this wide-ranging and vitally important subject, the present volume in the series will provide much food for thought.
