New found interest in the chromosome G-quadruplexes has emerged as an important focus of research in nucleic acids and as a potential target for cancer therapeutics. Existing literature concerning nucleic acids concentrates on aspects of quadruplex structure and historical research. There exists no single comprehensive resource addressing recent advances in therapeutic application and targeting strategies, until now. Quadruplex Nucleic Acids as Therapeutic Targets will be a vital resource for researchers in biochemistry, molecular biology, chemistry, biotechnology, biophysics, medicine, translational science and pharmacology. This timely publication is the first to offer practical application and direct strategies to meet the needs of emerging research.

Guanine rich DNA has been known for decades to form unusual structures, although their biological relevance was little understood. Recent advances have demonstrated that quadruplex structures can play a role in gene expression and provide opportunities for a new class of anticancer therapeutics. A number of quadruplex-specific proteins have also been discovered. Quadruplex Nucleic Acids discusses all aspects of the fundamentals of quadruplex structures, including their structure in solution and the crystalline state, the kinetics of quadruplex folding, and the role of cations in structure and stability. The biology of quadruplexes and G-rich genomic regions and G-quartets in supramolecular chemistry and nanoscience are also considered. Surveying the current state of knowledge, and with contributions from leading experts, this is the first comprehensive review of this rapidly growing area. Quadruplex Nucleic Acids is ideal for researchers interested in areas related to chemistry, chemical biology, medicinal chemistry, molecular pharmacology, and structural and molecular biology.

G-quadruplexes (G4s) are nucleic acids secondary structures that form in DNA or RNA guanine (G)-rich strands. In recent years, the presence of G4s in microorganisms has attracted increasing interest. In prokaryotes, G4 sequences have been reported in several human pathogens. Bacterial enzymes able to process G4s have been identified. In viruses, G4s have been suggested to be involved in key steps of the viral life cycle: They have been associated with the human immunodeficiency virus (HIV), herpes simplex virus 1 (HSV-1), human papilloma virus, swine pseudorabies virus, and other viruses’ genomes. New evidence shows the presence of G4s in parasitic protozoa, such as the causative agent of malaria. G4 binding proteins and mRNA G4s have been implicated in the regulation of microorganisms’ genome replication and translation. G4 ligands have been developed and tested both as tools to study the complexity of G4-mediated mechanisms in the viral life cycle and as therapeutic agents. Moreover, new techniques to study G4 folding and their interactions with proteins have been developed. This Special Issue will focus on G4s present in microorganisms, addressing all the above aspects.

This volume reviews numerous reaction mechanisms and applications of nucleic acids with catalytic activity. Written by an interdisciplinary team of authors, it provides an essential overview of these acids’ fundamental aspects, while also addressing associated methodologies such as nucleic acid enzyme engineering, peroxidase-mimicking DNAzymes and Aptazymes. After the discovery of natural ribozymes – RNA molecules that mediate the cleavage and formation of phosphodiester bonds and the formation of peptide bonds – numerous artificial ribozymes with altered catalytic activities were produced by in vitro and in vivo selection. Unlike ribozymes, DNAzymes do not occur in nature. Although the catalytic activity of nucleic acid enzymes is usually much slower than that of proteins, nucleic acid enzymes with comparable catalytic activity have been obtained using stringent selection processes. The key advantages of these enzymes: they are e.g. smaller, easier to produce and purify than proteins, and can withstand denaturation, e.g. by heat. Over the last few years, the number of publications on the applications of enzymatic nucleic acids has grown steadily. Summarizing the fundamentals and applications of these acids, this book will not only be an excellent resource for experts in the field but will also guide young researchers just starting out in this significant area.

This book is intended for non-specialists and students, presenting a unique introduction to the field of DNA nanotechnology. The primary focus is on the extraordinary advantages of specificity and sensitivity obtained by integrating DNA nanostructures in bioanalytical devices. DNA Nanotechnology for Bioanalysis provides a concise and rigorous description for the fabrication of various types of functional nanostructures by optimized software-aided high-yield synthesis. Following this is the explanation of methods to decorate these nanostructures with molecules such as proteins, metal nanoparticles or bioorganic moieties covalently bonded onto DNA via self-assemblage processes. Also provided is a concise review on non-canonical DNA structures (such as G-quadruplexes) and their targeting by small molecules for applications in pharmacology. Finally, it describes the exciting applications of DNA nanostructures in life sciences and nanomedicine, including ultraspecific molecular delivery, control of cell behavior, analysis of cell lysate and DNA-based nano-tools for super-resolution sub-cellular imaging.

Guanosine and its derivatives have a high potential for self-recognition and self-assembly, as well as the recognition ability for other biologically important molecules. This book explores in detail these properties with the goal of increasing knowledge of the basic principles of guanosine-assembly, synthesis of new optimised materials and exploration of their electronic and optical properties. Following the work of COST Action MP0802, the aim is to design novel reproducible and well ordered supramolecular structures to serve as molecular-scale architectures for new hybrid molecular electronics. Coverage includes synthesis, characterisation and optimisation, theoretical modelling and prediction, biochemical and biorecognition properties and applications in nanotechnology especially in molecular electronics. Appealing to researchers working in the field ranging from chemists, biologists and material scientists, this title will be a welcome addition to the inter-disciplinary literature providing direction for future research and ideas for industrial applications.
