The study of antiviral drug resistance has provided important insights into the structure of virus enzymes, the functions of certain genes, mechanisms of action of antiviral drugs, the design of new antiviral compounds and the pathogenesis of viral diseases. The emergence of resistant strains must be explored at all stages of drug development: during the preclinical evaluation of candidate compounds; during the early clinical evaluation of new drugs; and as part of epidemiological surveillance for the prevalence of resistance during use of approved treatments. Accumulating understanding of antiviral drug resistance thus reflects progress in the chemotherapy of viral infection. Antiviral Drug Resistance provides state-of-the-art coverage of the basic and clinical aspects of this subject. It deals with the basic science, including the mechanisms of drug resistance and drug action, genetics of drug resistance, cross resistance, and X-ray crystallographic structural aspects of resistance, as well as the clinical aspects, including issues of assay of susceptibility of clinical isolates, descriptive aspects of emergence of reduced susceptibility, and clinical significance and impact of resistance. As such this unique volume will be essential to basic researchers in drug discovery and viral pathogenesis, as well as clinicians involved in antiviral chemotherapy.

All these aspects are covered in depth, both scientifically and in terms of clinical guidelines for patient care. The text is illustrated generously throughout and is fully referenced to the latest research and developments.

Genetics and Evolution of Infectious Diseases, Third Edition discusses the evolving field of infectious diseases and their continued impact on the health of populations, especially in resource-limited areas of the world where they must confront the dual burden of death and disability due to infectious and chronic illnesses. Although substantial gains have been made in public health interventions for the treatment, prevention, and control of infectious diseases, in recent decades the world has witnessed the emergence of the human immunodeficiency virus (HIV) and the COVID-19 pandemic, increasing antimicrobial resistance, and the emergence of many new bacterial, fungal, parasitic, and viral pathogens. Fully updated and revised, this new edition presents the consequences of such diseases, the evolution of infectious diseases, the genetics of host-pathogen relationship, and the control and prevention strategies that are, or can be, developed. This book offers valuable information to biomedical researchers, clinicians, public health practitioners, decisions-makers, and students and postgraduates studying infectious diseases, microbiology, medicine, and public health that is relevant to the control and prevention of neglected and emerging worldwide diseases. - Takes an integrated approach to infectious diseases - Provides the latest developments in the field of infectious diseases - Focuses on the contribution of evolutionary and genomic studies for the study and control of transmissible diseases - Includes updated and revised contributions from leading authorities, along with six new chapters

A crucial issue for antiviral therapy is the fact that all antiviral substances rapidly select for resistance; thus, monitoring and overcoming resistance has become a most important clinical paradigm of antiviral therapy. This calls for cautious use of antiviral drugs and implementation of combination therapies. In parallel, efforts in drug discovery have to be continued to develop compounds with novel mode-of-action and activity against resistant strains. This book reviews the current status of antiviral therapy, from the roads to development of new compounds to their clinical use and cost effectiveness. Individual chapters address in more detail all available drug classes and outline new approaches currently under development.

Antimicrobial Drug Resistance presents information regarding the ability of organisms to resist natural and synthetically derived inhibitors. It presents the view of the authors who made significant contributions to the understanding of resistance. The book focuses on inhibitors classified as antifungal, antiviral, and antimalarial, as well as metal ions. It also covers numerous reactions, which have been genetically and biochemically analyzed in this context. Additionally, some chapters cover resistance plasmids of most of the clinically important bacteria. The book is designed to aid those involved in microbiological and pharmaceutical research on antimicrobial agents, clinical infectious diseases and medical microbiology, teaching microbiology and pharmacology, pharmaceutical marketing, and infection control.

This book focuses on new small molecule approaches to combat viral infections.

Organized by a virus (such as HIV, HCV, RSV, influenza, HBV and CMV) and written by top academic and industrial authorities in the field, the book provides a unique opportunity to study, understand and apply discovery and development principles and learning without the need for an individual to research, analyze and synthesize all immense sourcing references. Topics showcase challenges and solutions of issues encountered, offering tremendous experience accumulated over many years of research that will be particularly useful to basic and bench scientists as well as clinicians as they continue discovering and developing new drugs and therapies.

" . . . the motto for the therapeutics of the future will have to be de sedibus et causis pharmacorum. " P. EHRLICH, 1909 Exciting events in the basic disciplines of virology, immunology, and pharmacology continue to advance the understanding of the pathogenesis and control of virus diseases. At the same time, the rational development of antiviral agents is attracting, to an increasing extent, the interest of workers in other disciplines. Improvements in technology facilitate the definition of potential target sites for antiviral intervention and unmask new viral and host genes. The outcome is a further steady development of new antiviral agents which approach the "magic bullets" first proposed by PAUL EHRLICH. Remarkable advances in protein synthetic methods that yield polypeptides which inhibit active sites of viral proteins have aided substantially in the basic and clinical study of these antiviral agents. In addition, the extremely rapid progression in recombinant DNA techniques, leading to the synthesis of large quantities of gene products, is also increasing our opportunities at a dashing pace. New information and developing technology facilitate research on the mechanism of action, toxicity, pharmacokinetics, and pharmacodynamics of new agents. The list of clinically effective antiviral agents is expanding and the number of potentially useful compounds is growing rapidly. This book is a combined theoretical text and practical manual which, it is hoped, will be of use to all who have an interest in virus diseases, particularly scientists, physicians and graduate students.

Advances in genomic and proteomic profiling of disease have transformed the field of molecular diagnostics, thus leading the way for a major revolution in clinical practice. While the range of tests for disease detection and staging is rapidly expanding, many physicians lack the knowledge required to determine which tests to order and how to interpret results. Molecular Diagnostics provides a complete guide to the use and interpretation of molecular testing in the clinical arena. No other available resource offers this emphasis, comprehensive scope, and practical utility in the clinical setting. - Serves as the definitivereference for molecular pathologists worldwide - Covers a variety of molecular techniques including next generation sequencing, tumor somatic cell genotyping, infectious and genetic disease tecting, and pharmacogenetics - Discusses in the detail issues concerning quality assurance, regulation, ethics, and future directions for the science

The antiviral therapeutic area continues to rapidly generate meaningful new chemical entities; for example, for HIV alone more than 25 drugs have been approved, and in the next few years many individual drugs and single tablet regimens will be approved for the treatment of hepatitis C virus infection. The increasing success in the antiviral area could be due to targeting drugs at "non-self" genomes and to the patient population that is tolerant of manageable side effects and adaptable to inconvenient dosing. Aimed at medicinal chemists and emerging drug discovery scientists, the book is organized according to the various strategies deployed for the discovery and optimization of initial lead compounds. This book focuses on capturing tactical aspects of problem solving in antiviral drug design, an approach that holds special appeal for those engaged in antiviral drug development, but also appeals to the broader medicinal chemistry community based on its focus on tactical aspects of drug design.

This book summarizes state-of-the-art antiviral drug design and discovery approaches starting from natural products to de novo design, and provides a timely update on recently approved antiviral drugs and compounds in advanced clinical development. Special attention is paid to viral infections with a high impact on the world population or highly relevant from the public health perspective (HIV, hepatitis C, influenza virus, etc.). In these chapters, limitations associated with adverse effects and emergence of drug resistance are discussed in detail. In addition to classical antiviral strategies, chapters will be dedicated to discuss the non-classical drug development strategies to block viral infection, for instance, allosteric inhibitors, covalent antiviral agents, or antiviral compounds targeting protein–protein interactions. Finally, current prospects for producing broad-spectrum antiviral inhibitors will be also addressed. The book is distinctive in providing the most recent update in the rapidly evolving field of antiviral therapeutics. Authoritative reviews are written by international scientists well known for their contributions in their topics of research, which makes this book suitable for researchers not only within the antiviral research community but also attractive to a broad audience in the drug discovery field.
