SETS FORTH A FRAMEWORK FOR THE ANALYSIS AND STUDY OF FLAVONOIDS More and more dietary supplements contain flavonoids. These products are typically viewed as food rather than drug products by regulatory agencies and therefore not subjected to rigorous clinical trials before they are marketed to the general public. As a result, the use of flavonoid-containing supplements presents a potential public health risk. From discovery to therapeutic application, this book is a comprehensive guide to both achiral and chiral flavonoids, enabling researchers to perform essential preclinical and clinical pharmacokinetics studies in order to ensure the efficacy of flavonoids marketed for therapeutic use. Moreover, the book examines the safety and toxicology of flavonoids as well as flavonoid-drug interactions. With contributions from a multidisciplinary team of leading researchers, Flavonoids Pharmacokinetics reviews and synthesizes the most recent research findings and results from preclinical and clinical studies. The book begins with a comprehensive overview of polyphenols and flavonoids. Next, the book covers: Methods of analysis of achiral flavonoids Preclinical pharmacokinetic of flavonoids Toxicology and safety of flavonoids Methods of analysis for chiral flavonoids Clinical pharmacokinetics of flavonoids Flavonoids and drug interactions Throughout the book, the authors provide examples that demonstrate the use of pharmacokinetics concepts during the preclinical and clinical drug development process. Flavonoid Pharmacokinetics is written for pharmaceutical, food, and nutritional scientists and students, offering the tools they need to thoroughly analyze and test flavonoids and flavonoid-containing supplements to ensure their safety and efficacy.

Flavonoids are ubiquitously present in plant-based foods and natural health products. The molecule of flavonoids is characterized by a 15-carbon skeleton of C6–C3–C6, with the different structural configuration of subclasses. The major subclasses of flavonoids with health-promotional properties are the flavanols or catechins (e.g., epigallocatechin 3-gallate from green tea), the flavones (e.g., apigenin from celery), the flavonols (e.g., quercetin glycosides from apples, berries, and onion), the flavanones (e.g., naringenin from citrus), the anthocyanins (e.g., cyanidin-3-O-glucoside from berries), and the isoflavones (e.g., genistein from soya beans). Scientific evidence has strongly shown that regular intake of dietary flavonoids in efficacious amounts reduces the risk of oxidative stress- and chronic inflammation-mediated pathogenesis of human diseases such as cardiovascular disease, certain cancers, and neurological disorders. The physiological benefits of dietary flavonoids have been demonstrated to be due to multiple mechanisms of action, including regulating redox homeostasis, epigenetic regulations, activation of survival genes and signaling pathways, regulation of mitochondrial function and bioenergetics, and modulation of inflammation response. The role of flavonoids on gut microbiota and the impact of microbial metabolites of flavonoids on optimal health has begun to unravel. The complex physiological modulations of flavonoid molecules are due to their structural diversity. However, some flavonoids are not absorbed well, and their bioavailability could be enhanced through structural modifications and applications of nanotechnology, such as encapsulation. This Special Issue consists of four review articles on flavonoids and 15 original research articles, which cover the latest findings on the role of dietary flavonoids and their derivatives in disease prevention and treatment.

Polyphenols: Mechanisms of Action in Human Health and Disease, Second Edition describes the mechanisms of polyphenol antioxidant activities and their use in disease prevention. Chapters highlight the anti-inflammatory activity of polyphenols on key dendritic cells, how they modulate and suppress inflammation, and how they are inactivated or activated by metabolism in the gut and circulating blood. Polyphenols have proven effective for key health benefits, including bone health, organ health, cardiac and vascular conditions, absorption and metabolism, and cancer and diseases of the immune system. They are a unique group of phytochemicals that are present in all fruits, vegetables and other plant products. This very diverse and multi-functional group of active plant compounds contain powerful antioxidant properties and exhibit remarkable chemical, biological and physiological properties, including cancer prevention and cardio-protective activities. - Expands coverage on green tea, cocoa, wine, cumin and herbs - Outlines their chemical properties, bioavailability and metabolomics - Provides a self-teaching guide to learn the mechanisms of action and health benefits of polyphenols

A practice-oriented desktop reference for medical professionals, toxicologists and pharmaceutical researchers, this handbook provides systematic coverage of the metabolic pathways of all major classes of xenobiotics in the human body. The first part comprehensively reviews the main enzyme systems involved in biotransformation and how they are orchestrated in the body, while parts two to four cover the three main classes of xenobiotics: drugs, natural products, environmental pollutants. The part on drugs includes more than 300 substances from five major therapeutic groups (central nervous system, cardiovascular system, cancer, infection, and pain) as well as most drugs of abuse including nicotine, alcohol and "designer" drugs. Selected, well-documented case studies from the most important xenobiotics classes illustrate general principles of metabolism, making this equally useful for teaching courses on pharmacology, drug metabolism or molecular toxicology. Of particular interest, and unique to this volume is the inclusion of a wide range of additional xenobiotic compounds, including food supplements, herbal preparations, and agrochemicals.

Medicinal chemists around the world have been inspired by nature and have successfully extracted chemicals from plants.
