Book Description
The ability of DNA to exist in configurations other than its classical double-stranded form has been known for many years. There has been a spectacular recent surge of interest in these forms, notably in the three-stranded or triple-helical form. Triplex-like nucleic acids are now known to exist in vivo, and may well participate in significant biological processes. Interest in triple-helical nucleic acids has been greatly stimulated by their potential exploitation to control gene expression, serve as tools in genome mapping strategies, etc. The authors have written an encyclopedic introduction to nucleic acid triplexes based on many years of familiarity with the topic. The book includes information on chemistry, conformation, physical properties, applications, and hypotheses about the biological role of triplexes. It pays particular attention to the different methods for investigating these molecules, a feature which will be welcomed by those new to the field.

Book Description
Sequence-specific DNA binding ligands, amongst which triple helix forming oligonucleotides are the most efficient as yet, represent promising tools in a number of fields. One of their most promising applications is as antiviral tools: they can specifically target a viral gene, even if it is integrated into the host genome, and be used to specifically inactivate the viral gene or even destroy the cells harboring this gene. However, from science fiction to science there remains a gap; and we are at the moment on the threshold of this fascinating field. Triple Helix Forming Oligonucleotides considers the different aspects of the design and improvement, current or future, of these molecules and their structural analysis, as well as their applications, with special emphasis on the attempts to obtain biological effects of these potentially important tools. What emerges is that the current state of the research is encouraging, and that these molecules are already useful in some biotechnology applications.

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
Life in all its forms is based on nucleic acids which store and transfer genetic information. The book addresses main aspects of synthesis, hydrolytic stability and solution equilibria of nucleosides, nucleotides and oligonucleotides, as well as synthesis of their structural analogs that are of interest in chemotherapy. In addition, recent achievements in chemistry of catalytic nucleic acids, development of oligonucleotide based drugs and novel strategies for their targeting and delivery are discussed. The central theme always is the correlation of structure and function.

Book Description
New textbooks at all levels of chemistry appear with great regularity. Some fields like basic biochemistry, organic reaction mechanisms, and chemical ther modynamics are well represented by many excellent texts, and new or revised editions are published sufficiently often to keep up with progress in research. However, some areas of chemistry, especially many of those taught at the grad uate level, suffer from a real lack of up-to-date textbooks. The most serious needs occur in fields that are rapidly changing. Textbooks in these subjects usually have to be written by scientists actually involved in the research which is advancing the field. It is not often easy to persuade such individuals to set time aside to help spread the knowledge they have accumulated. Our goal, in this series, is to pinpoint areas of chemistry where recent progress has outpaced what is covered in any available textbooks, and then seek out and persuade experts in these fields to produce relatively concise but instructive introductions to their fields. These should serve the needs of one semester or one quarter graduate courses in chemistry and biochemistry. In some cases the availability of texts in active research areas should help stimulate the creation of new courses. CHARLES R. CANTOR New York Preface This monograph is based on a review on polynucleotide structures written for a book series in 1976.

Book Description
MILS-16 provides an up-to-date review of the impact of alkali metal ions on life. Their bioinorganic chemistry and analytical determination, the solid state structures of bio-ligand complexes and the properties of alkali metal ions in solution in the context of all kinds of biologically relevant ligands are covered, this includes proteins (enzymes) and nucleic acids (G-quadruplexes). Minerals containing sodium (Na+) and potassium (K+) are abundant in the Earth's crust, making Na+ and K+ easily available. In contrast, the alkali elements lithium (Li+), rubidium, and cesium are rare and the radioactive francium occurs only in traces. Since the intra- and extracellular, as well as the compartmental concentrations of Na+ and K+ differ significantly, homeostasis and active transport of these ions are important; this involves transporters/carriers and pore-forming ion channel proteins. Systems like Na+/K+-ATPases, H+/K+-ATPases or Na+/H+ antiporters are thoroughly discussed. The role of K+ in photosynthesis and the role of Na+ in charging the "battery of life" are pointed out. Also, the relationships between alkali metal ions and diseases (e.g., Parkinson or traumatic brain injury) are covered and the relevance of Li+ salts in medicine (pharmacology and mechanism) is reviewed. This and more is treated in an authoritative and timely manner in the 16 stimulating chapters of Volume 16, The Alkali Metal Ions: Their Role for Life, which are written by 44 internationally recognized experts from 12 nations. The impact of this vibrant research area is manifested in nearly 3000 references, over 30 tables and more than 150 illustrations (two thirds in color). MILS-16 also provides excellent information for teaching. Astrid Sigel, Helmut Sigel, and Roland K. O. Sigel have long-standing interests in Biological Inorganic Chemistry. Their research focuses on metal ion interactions with nucleotides and nucleic acids and on related topics. They edited previously 44 volumes in the series Metal Ions in Biological Systems.
