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.

Microsomes, Drug Oxidations, and Chemical Carcinogenesis, Volume I, 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. The book contains 117 contributions made by researchers at the symposium, which are organized into three sections. The papers in Section I focus on the chemical and physical characteristics of cytochrome P-450. Section II examines the mechanisms of action of cytochrome P-450 and related enzymes. The studies in Section III deal with the influence of membrane structure and protein synthesis on electron transfer components. 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.

Proceedings of the Fifth International Symposium on Microsomes and Drug Oxidations held in Tokyo, July 1981. Researchers from a wide range of disciplines discuss recent developments in the field. Emphasizes the characterization and mechanisms of action of cytochrome P-450 and related enzymes; microsomal metabolism of endogenous substrates; regulation of microsomal metabolism; and metabolic activation and drug toxicity.

Microsomes and Drug Oxidations is a record of the proceedings of the Third International Symposium on Microsomes and Drug Oxidations, held in Berlin, Germany in July 1976. The compendium provides an overview of knowledge on the oxidative metabolism of drugs, carcinogens, and various other environmental chemicals. Topics discussed include lipid structure of liver microsomal membranes; interactions between cytochrome p-450 and nadphcytochrome p-450 reductase in the microsomal membrane; impact of drug monoxygenases in clinical pharmacology; and the manner in which oxygen participates in mixed-function oxidation reactions. Pharmacologists, toxicologists, biochemists, and researchers in the pharmaceutical industry will find the book highly insightful.

This book is one of a GANN Monograph on Cancer Research series and is based on a Japanese Cancer Association-sponsored symposium entitled "Multiplicity of Chemical Carcinogen-Activating Enzymes· with Particular Emphasis on Cytochrome P-450" which was held in Tokyo on November 21, 1983. The principal role of microsomal cytochrome P-450 in the metabolic activation of various chemical carcinogens in animal cells has been well established. The activated chemical carcinogens induce mutations of the cells, which is an essential part of the initiation of chemical carcinogenesis. Since microsomal cytochrome P-450 in various animal tissues includes multiple molecular species with different substrate specificities and different responses to chemical inducers, knowledge of the molecular and catalytic properties and the inducibilities of those cytochrome P-450 forms is surely a most important base from which to elucidate the mechanism of chemical carcinogenesis. The focus of the symposium was this area of molecular diversity and inducibility of microsomal cytochrome P-450 in animal tissues. The mechanism of activation of various types of chemical carcinogens by cytochrome P-450 and related enzymes was another main topic. The editors, who were also the symposium organizers, hope these summaries of current research in this field in Japan will stimulate future development of studies on the mechanism of chemical carcinogenesis.
