Book Description
Metabolic Inhibitors: A Comprehensive Treatise, Volume II charts the major advances that have been made in understanding metabolic inhibition and inhibitors. The book explores the inhibition of enzymes, such as catechol amines, acetylcholinesterases, and succinic dehydrogenases, as well as inhibitors of processes ranging from gas transport to photosynthesis, nitrogen fixation, nitrification, and oxidative phosphorylation. Organized into 23 chapters, this volume begins with a discussion on the biosynthesis of nicotinamide adenine dinucleotide and dinucleotide analogues. The reader is then introduced to the biochemical significance and mode of action of antibiotics; substances interfering with the biogenesis and metabolism of catechol amines; and inhibition of enzyme activities by thioarsenites. Some chapters focus on mercaptide-forming agents, biological alkylating agents, organophosphates, and carbamates, while others examine the metabolic inhibitory effects of quinones, fungicides, and surface active agents. The book also considers the effects of anesthetics, depressants, and tranquilizers on cerebral metabolism, and then concludes with a chapter on inhibition caused by radiation. This book is a valuable resource for biochemists, advanced students, medical research workers, and research workers in the fields of biological chemistry, microbiology, botany, and agriculture.

Book Description
Genetic alterations in cancer, in addition to being the fundamental drivers of tumorigenesis, can give rise to a variety of metabolic adaptations that allow cancer cells to survive and proliferate in diverse tumor microenvironments. This metabolic flexibility is different from normal cellular metabolic processes and leads to heterogeneity in cancer metabolism within the same cancer type or even within the same tumor. In this book, we delve into the complexity and diversity of cancer metabolism, and highlight how understanding the heterogeneity of cancer metabolism is fundamental to the development of effective metabolism-based therapeutic strategies. Deciphering how cancer cells utilize various nutrient resources will enable clinicians and researchers to pair specific chemotherapeutic agents with patients who are most likely to respond with positive outcomes, allowing for more cost-effective and personalized cancer therapeutic strategies.

Book Description
Since the discovery of the first examples of 2-oxoglutarate-dependent oxygenase-catalysed reactions in the 1960s, a remarkably broad diversity of alternate reactions and substrates has been revealed, and extensive advances have been achieved in our understanding of the structures and catalytic mechanisms. These enzymes are important agrochemical targets and are being pursued as therapeutic targets for a wide range of diseases including cancer and anemia. This book provides a central source of information that summarizes the key features of the essential group of 2-oxoglutarate-dependent dioxygenases and related enzymes. Given the numerous recent advances and biomedical interest in the field, this book aims to unite the latest research for those already working in the field as well as to provide an introduction for those newly approaching the topic, and for those interested in translating the basic science into medicinal and agricultural benefits. The book begins with four broad chapters that highlight critical aspects, including an overview of possible catalytic reactions, structures and mechanisms. The following seventeen chapters focus on carefully selected topics, each written by leading experts in the area. Readers will find explanations of rapidly evolving research, from the chemistry of isopenicillin N synthase to the oxidation mechanism of 5-methylcytosine in DNA by ten-eleven-translocase oxygenases.

Book Description
The science and applied approaches of enzyme inhibition in drug discovery and development Offering a unique approach that includes both the pharmacologic and pharmaco-kinetic aspects of enzyme inhibition, Enzyme Inhibition in Drug Discovery and Development examines the scientific concepts and experimental approaches related to enzyme inhibition as applied in drug discovery and drug development. With chapters written by over fifty leading experts in their fields, Enzyme Inhibition in Drug Discovery and Development fosters a cross-fertilization of pharmacology, drug metabolism, pharmacokinetics, and toxicology by understanding the "good" inhibitions—desirable pharmacological effects—and "bad" inhibitions—drug–drug interactions and toxicity. The book discusses: The drug discovery process, including drug discovery strategy, medicinal chemistry, analytical chemistry, drug metabolism, pharmacokinetics, and safety biomarker assessment The manipulations of drug metabolizing enzymes and transporters as well as the negative consequences, such as drug–drug interactions The inhibition of several major drug target pathways, such as the GPCR pathway, the NFkB pathway, and the ion channel pathway Through this focused, single-source reference on the fundamentals of drug discovery and development, researchers in drug metabolism and pharmacokinetics (DMPK) will learn and appreciate target biology in drug discovery; discovery biologists and medicinal chemists will also broaden their understanding of DMPK.

Book Description
Microsomes, Drug Oxidations, and Chemical Carcinogenesis, Volume II, documents the proceedings of the 4th International Symposium on Microsomes and Drug Oxidations held in Ann Arbor, July 1979. The symposium reviewed progress in the understanding of scientific and biomedical problems from a biochemical, biophysical, pharmacological, and toxicological perspective. Volume I contained 117 contributions made by researchers at the symposium, which were organized into three sections (Sections I-III). This second volume contains 122 contributions, divided into four sections (Sections IV-VII). The papers on Section IV examine the metabolic fate of oxygenated compounds. Section V provides studies on microsomal enzymes and lipid metabolism. Section VI includes papers on microsomal enzymes and toxicity of foreign compounds. Section VII covers microsomal enzymes and chemical mutagenesis and carcinogenesis. This book seeks to aid future progress in understanding the complexities of metabolic transformations by these versatile enzyme systems that act on physiologically important lipids as well as on a wide array of foreign substances, including drugs, anesthetics, industrial chemicals, food additives, pesticides, carcinogens, and nonnutrient dietary chemicals.

Book Description
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.

Book Description
Spore Research 1976, Volume II presents some of the papers reported at the meeting of British Spore Group held at the University of Leeds in December 1975. Organized into four headings, this volume focuses on aspects of heat and radiation resistance, germination, outgrowth, taxonomy, and ecology of spore formers. Specific discussions are given on the role of osmoregulation in the heat resistance, radiobiological evidence for the existence of dehydrated core in bacterial spores, some ecological implications of the diversity of spore-forming bacteria, and other topics relating to a specific spore former.
