This book, "Cytochromes P450: Drug Metabolism, Bioactivation and Biodiversity", presents five papers on human cytochrome P450 (CYP) and P450 reductase, three reviews on the role of CYPs in humans and their use as biomarkers, six papers on CYPs in microorganisms, and one study on CYP in insects. The first paper reports the in silico modeling of human CYP3A4 access channels. The second uses structural methods to explain the mechanism-based inactivation of CYP3A4 by mibefradil, 6,7-dihydroxy-bergamottin, and azamulin. The third article compares electron transfer in CYP2C9 and CYP2C19 using structural and biochemical methods, and the fourth uses kinetic methods to study electron transfer to CYP2C8 allelic mutants. The fifth article characterizes electron transfer between the reductase and CYP using in silico and in vitro methods, focusing on the conformations of the reductase. Then, two reviews describe clinical implications in cardiology and oncology and the role of fatty acid metabolism in cardiology and skin diseases. The second review is on the potential use of circulating extracellular vesicles as biomarkers. Five papers analyze the CYPomes of diverse microorganisms: the Bacillus genus, Mycobacteria, the fungi Tremellomycetes, Cyanobacteria, and Streptomyces. The sixth focuses on a specific Mycobacterium CYP, CYP128, and its importance in M. tuberculosis. The subject of the last paper is CYP in Sogatella furcifera, a plant pest, and its resistance to the insecticide sulfoxaflor.

Absorption, Distribution, Metabolism and Excretion (ADME) processes and their relationship with the design of dosage forms and the success of pharmacotherapy form the basis of this upper level undergraduate/graduate textbook. As an introduction oriented to pharmacy students, it is also written for scientist from different fields outside of pharmaceutics. (e.g. material scientist, material engineers, medicinal chemists) who might be working in a positions in pharmaceutical companies or whose work might benefit from basic training in the ADME concepts and some biological background. Pedagogical features such as objectives, keywords, discussion questions, summaries and case studies add valuable teaching tools. This book will provide not only general knowledge on ADME processes but also an updated insight on some hot topics such as drug transporters, multi-drug resistance related to pharmacokinetic phenomena, last generation pharmaceutical carriers (nanopharmaceuticals), in vitro and in vivo bioequivalence studies, biopharmaceuticals, pharmacogenomics, drug-drug and food-drug interactions, and in silico and in vitro prediction of ADME properties. In comparison with other similar textbooks, around half of the volume would be focused on the relationship between expanding scientific fields and ADME processes. Each of these burgeoning fields has a separate chapter in the second part of the volume, and was written with leading experts on the correspondent topic, including scientists and academics from USA and UK (Duquesne University School of Pharmacy, Indiana University School of Medicine, University of Utah College of Pharmacy, University of Maryland, University of Bath). Additionally, each of the initial chapters dealing with the generalities of drug absorption, distribution, metabolism and excretion would include relevant, classic examples related to each topic with appropriate illustrations (e.g. importance of active absorption of levodopa, implications in levodopa administration, drug drug interactions and food drug interactions emerging from the active uptake; intoxication with paracetamol as a result of glutathione depletion, CYP induction and its relationship with acute liver failure caused by paracetamol, etc). ADME Processes and Pharmaceutical Sciences is written as a core textbook for ADME processes, pharmacy, pharmacokinetics, drug delivery, biopharmaceutics, drug disposition, drug design and medicinal chemistry courses.

Humans are exposed to foreign compounds such as drugs, household products and environmental chemicals by swallowing or breathing. Also, food is considered a foreign compound. Such foreign compounds can be non-essential and non-functional to life, and commonly are referred to as xenobiotics. Some xenobiotics are not toxic; however, many of them are potentially toxic or become toxic after conversion to metabolic intermediates. A considerable number of foreign compounds belong to non-polar, lipophilic substances. Lipophilic compounds are not soluble in water. Metabolic conversion of lipophilic foreign compounds to facilitate their removal from the body is essentially carried out by biochemical reactions catalyzed by two classes of metabolizing enzymes, namely, activation enzymes and detoxification enzymes. Activation enzyme-catalyzed functionalization reaction introduces a functional group to a lipophilic compound. Functionalization modifies many foreign compounds to form reactive intermediates capable of interacting with cellular components (proteins, DNA and lipids), leading to a variety of conditions for diseases. Functionalized compounds are further metabolized through detoxification enzyme-catalyzed reactions, which result in an increase in the solubility of parent compounds and an inactivation of metabolic intermediates, thus facilitating their excretion from the body. To minimize the exposure of potentially toxic metabolic intermediates, it is essential to keep them at a minimum level. Extensive investigations have revealed that foreign compound-metabolizing enzymes exhibit genetic polymorphisms. Variations in their activities can produce different results as to the susceptibility to potential toxic effects. Moreover, the expressions of activation enzymes and detoxification enzymes are inducible. A number of chemical compounds are capable of acting as modulators for these two classes of enzymes. These findings have lead to the proposal of modulating metabolizing enzymes as a useful approach for human health benefits. Importantly, many of these chemical compounds are present in human daily diets. There are many advances that have been made in the past decades towards the understanding of functions and implications of activation enzymes and detoxification enzymes. An organized, concise overview is needed for the readers who are initially exposed to this important subject, particularly for students and researchers in the areas of biomedical sciences, biochemistry, nutrition, pharmacology and chemistry. This book is intended to serve this purpose as an introduction to the subject. Furthermore, major topics in the book, excluding catalytic reactions and structural properties, may have interest to other readers who have knowledge of basic sciences and understanding enzyme related information. The book discusses subjects associated with foreign compound metabolizing enzymes with emphasis on biochemical aspects, including lipophilic foreign compounds, catalytic properties, reactive intermediates, biomedical and biochemical effects, genetic polymorphisms, enzyme inducibility, enzyme modulation for health benefits, dietary related enzyme modulators, and structural characteristics of enzyme inducers.

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.

Handbook of Drug-Nutrient Interactions, Second Edition is an essential new work that provides a scientific look behind many drug-nutrient interactions, examines their relevance, offers recommendations, and suggests research questions to be explored. In the five years since publication of the first edition of the Handbook of Drug-Nutrient Interactions new perspectives have emerged and new data have been generated on the subject matter. Providing both the scientific basis and clinical relevance with appropriate recommendations for many interactions, the topic of drug-nutrient interactions is significant for clinicians and researchers alike. For clinicians in particular, the book offers a guide for understanding, identifying or predicting, and ultimately preventing or managing drug-nutrient interactions to optimize patient care. Divided into six sections all chapters have been revised or are new to this edition. Chapters balance the most technical information with practical discussions and include outlines that reflect the content; discussion questions that can guide the reader to the critical areas covered in each chapter, complete definitions of terms with the abbreviation fully defined and consistent use of terms between chapters. The editors have performed an outstanding service to clinical pharmacology and pharmaco-nutrition by bringing together a multi-disciplinary group of authors. Handbook of Drug-Nutrient Interactions, Second Edition is a comprehensive up-to-date text for the total management of patients on drug and/or nutrition therapy but also an insight into the recent developments in drug-nutrition interactions which will act as a reliable reference for clinicians and students for many years to come.
