Peptide nucleic acids (PNAs) have now existed for slightly more than ten years, with the interest in and applications of this pseudopeptide DNA mimic steadily increasing during the entire period. PNAs have rapidly attracted the attention of scientists from a diversity of fields ranging from (bio)organic and biophysical chemistry to prebiotic evolution, and from molecular biology to genetic diagnostics and drug development. Many of the applications take advantage of the unique properties of PNA—an uncharged pseudopeptide—that distinguish this DNA mimic from more traditional DNA analogs. Rather than trying to create a comprehensive collection of all published methods and protocols involving PNA—many of which have not yet been validated— I have decided to concentrate on select protocols that are either very well established by several groups around the world, such as PCR-clamping and in situ hybridization, or on new methods that may have broader future impact. Basic methods for PNA oligomer synthesis and analyses have also been included. I am very grateful to those friends and colleagues who have enthusiastically contributed their work, discussions, and writing, and thereby made this book possible. Peter E.

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.

This book compiles four review articles and four research papers that highlight recent developments in the field of peptide nucleic acid (PNA) chemistry and biomedicine. The review articles encompass a variety of fields related to PNA, emphasizing the versatility of this DNA mimic. Two excellent reviews detail the use of PNA for molecular diagnostics of miRNAs and genetic point mutations (SNPs). Another review provides a comprehensive analysis of the various approaches for gene editing using chemically modified PNA molecules. Lastly, PNA molecules are elegantly described as effective (antisense) antimicrobial agents in the final review. The high binding affinity of PNA to complementary DNA and RNA is highlighted in three research articles. Two articles show how PNA molecules act as splice modulating and RNA masking molecules, separately. In another contribution, the high affinity and achiral characteristics of PNAs are used to developed a stable L-DNA-based catalytic hairpin assembly. Lastly, chemically-modified PNA molecules are shown to be superior probes for SNP detection. Altogether, these studies illustrate how PNA molecules may be useful for a variety of biomedical applications as either therapeutic or diagnostic agents.

Advances in biotechnology have provided scientists with an increasing number of biopharmaceuticals such as novel peptide and protein drugs as well as nucleic acid based drugs for gene therapy. However, successful delivery of these biopharmaceuticals is a major challenge because their molecular properties lead to poor physical and chemical stability in the body and limited membrane permeability. Therefore researchers are developing a range of new delivery technologies and materials to enable these new drugs to be delivered intact to their target sites. Delivery Technologies for Biopharmaceuticals describes strategies to overcome the main barriers for successful delivery of therapeutic peptides, proteins, and nucleic acid-based drugs or vaccines related to the site of administration and the target site. Many of the approaches described are reported in formulations in current clinical trials as well as in marketed products. Contents include: challenges in delivery of biopharmaceuticals novel formulation approaches for peptide and protein injectables non-viral chemical vectors and viral technology for delivery of nucleic acid based drugs immune response, adjuvants and delivery systems for vaccines several examples of delivery systems for different biopharmaceuticals a critical assessment of delivery technologies for biopharmaceuticals Delivery Technologies for Biopharmaceuticals is an essential single-volume introduction to the technologies used by researchers to ensure efficient delivery of this exciting new class of drugs. It will be of value to researchers and students working in drug delivery, formulation, biopharmaceuticals, medicinal chemistry, and new materials development.
