Book Description
This book examines genotoxic impurities and their impact on the pharmaceutical industry. Specific sections examine this from both a toxicological and analytical perspective. Within these sections, the book defines appropriate strategies to both assess and ultimately control genotoxic impurities, thus aiding the reader to develop effective control measures. An opening section covers the development of guidelines and the threshold of toxicological concern (TTC) and is followed by a section on safety aspects, including safety tests in vivo and vitro, and data interpretation. The second section addresses the risk posed by genotoxic impurities from outside sources and from mutagens within DNA. In the final section, the book deals with the quality perspective of genotoxic impurities focused on two critical aspects, the first being the analysis and the second how to practically evaluate the impurities.

Book Description
Mutagenicity: Assays and Applications presents an extensive examination of the detection, assessment and future of mutagenicity, particularly as it concerns human health and the environment. Chapters focused on specific types of mutagens or testing methods for their detection collectively explore the current state of human and environmental mutagenesis, future perspectives and regulatory needs. The test procedures for measuring mutagenicity, their advantages and limitations are described with practical and procedural detail, along with their presentation and data processing aspects. It is an essential reference covering the breadth and depth of the field of mutagenicity studies and regulation. By providing both important introductory material and practical assays and applications, this book is useful to graduate students, academic and industry researchers and regulators at various stages of their careers, leading to improved risk assessment and regulation. Presents an up-to-date and in-depth review of the current state of mutagenesis research Draws upon the combined experience and expertise of an international group of highly respected editors and chapter authors Provides an introduction to the concept of mutagenesis with particular consideration given to novel chemicals and materials

Book Description
Medicinal chemistry is a complex science that lies at the very heart of drug discovery. Poor solubility, complex metabolism, tissue retention and slow elimination are just some of the properties of investigational compounds that present a challenge to the design and conduct of ADMET studies. Medicinal chemistry experience and knowledge relating to how a lead structure was modified to solve a specific problem is generally very challenging to retrieve. Presented in a visual and accessible style, this book provides rapid solutions to overcome the universal challenges to optimizing ADMET.

Book Description
A comprehensive review of contemporary antisense oligonucleotides drugs and therapeutic principles, methods, applications, and research Oligonucleotide-based drugs, in particular antisense oligonucleotides, are part of a growing number of pharmaceutical and biotech programs progressing to treat a wide range of indications including cancer, cardiovascular, neurodegenerative, neuromuscular, and respiratory diseases, as well as other severe and rare diseases. Reviewing fundamentals and offering guidelines for drug discovery and development, this book is a practical guide covering all key aspects of this increasingly popular area of pharmacology and biotech and pharma research, from the basic science behind antisense oligonucleotides chemistry, toxicology, manufacturing, to safety assessments, the design of therapeutic protocols, to clinical experience. Antisense oligonucleotides are single strands of DNA or RNA that are complementary to a chosen sequence. While the idea of antisense oligonucleotides to target single genes dates back to the 1970's, most advances have taken place in recent years. The increasing number of antisense oligonucleotide programs in clinical development is a testament to the progress and understanding of pharmacologic, pharmacokinetic, and toxicologic properties as well as improvement in the delivery of oligonucleotides. This valuable book reviews the fundamentals of oligonucleotides, with a focus on antisense oligonucleotide drugs, and reports on the latest research underway worldwide. • Helps readers understand antisense molecules and their targets, biochemistry, and toxicity mechanisms, roles in disease, and applications for safety and therapeutics • Examines the principles, practices, and tools for scientists in both pre-clinical and clinical settings and how to apply them to antisense oligonucleotides • Provides guidelines for scientists in drug design and discovery to help improve efficiency, assessment, and the success of drug candidates • Includes interdisciplinary perspectives, from academia, industry, regulatory and from the fields of pharmacology, toxicology, biology, and medicinal chemistry Oligonucleotide-Based Drugs and Therapeutics belongs on the reference shelves of chemists, pharmaceutical scientists, chemical biologists, toxicologists and other scientists working in the pharmaceutical and biotechnology industries. It will also be a valuable resource for regulatory specialists and safety assessment professionals and an important reference for academic researchers and post-graduates interested in therapeutics, antisense therapy, and oligonucleotides.

Book Description
This unique new reference contains the Carcinogenic Potency Database (CPDB), which analyzes results of decades of animal cancer tests, including all Technical Reports of the National Toxicology Program (NTP) and the general published literature. A guide to the literature of animal cancer tests, the CPDB includes references to each published experiment and never-before published analyses. For each of 5,000 long-term experiments on 1,300 chemicals, the user-friendly format includes data on the species, strain, and sex of the test animal; features of experimental protocol such as the route of administration, duration of dosing, dose levels, and duration of the experiment; histopathology and tumor incidence; the shape of the dose-response curve; published author's opinion about the carcinogenicity at each site; and reference to the original publication of the test results. In addition, a measure of carcinogenic potency, the TD50, its statistical significance and confidence limits, are given for each tumor site. An overview is provided of earlier publication updates, such as positivity rates, reproducibility, interspecies extrapolation, and ranking possible carcinogenic hazards. The book also includes a summary of the NTP genetic toxicity test results on 1,500 chemicals, which are referenced to the original publications, including the Salmonella (Ames) test, L5178Y mouse lymphoma cell mutation test, chromosome aberration and sister chromatid exchange tests in cultured Chinese hamster ovary cells, and the sex-linked recessive lethal mutation test in Drosophila melanogaster. An index with chemicals listed by CAS number allows cross referencing between the carcinogenicity and genotoxicity databases, making data easy to find.

Book Description
Most people associate fluoride with the practice of intentionally adding fluoride to public drinking water supplies for the prevention of tooth decay. However, fluoride can also enter public water systems from natural sources, including runoff from the weathering of fluoride-containing rocks and soils and leaching from soil into groundwater. Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States fluoride concentrations in water are much higher than normal, mostly from natural sources. Fluoride is one of the drinking water contaminants regulated by the U.S. Environmental Protection Agency (EPA) because it can occur at these toxic levels. In 1986, the EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter, a guideline designed to prevent the public from being exposed to harmful levels of fluoride. Fluoride in Drinking Water reviews research on various health effects from exposure to fluoride, including studies conducted in the last 10 years.
