Modern Methods of Steroid Analysis reviews modern methods of steroid analysis such as liquid column chromatography, mass spectrometry, and gas chromatography. Topics covered include qualitative and quantitative analysis of plant sterols by gas-liquid chromatography; Raman spectroscopy of steroids; nuclear magnetic resonance; and applications of lanthanide shift reagents. A computerized method for rapid comparison and retrieval of infrared spectral data is also described. This volume is comprised of 22 chapters and begins with an analysis of hormonal steroids using liquid column chromatography, followed by a discussion on the separation of insect molting hormones using high-pressure liquid chromatography. The reader is methodically introduced to the application of gradient elution and thin-layer chromatography to the analysis of corticosteroids and 17-ketosteroids, as well as some aspects of mass spectrometry in steroid analysis. Subsequent chapters explore other methods such as optical rotatory dispersion and circular dichroism, along with radioisotope techniques. In particular, the radioimmunoassay of plasma steroid hormones and plasma aldosterone is considered. This book should be of interest to biochemists.

Studies in Analytical Chemistry, Volume 5: Quantitative Analysis of Steroids covers the pharmaceutical aspects of the analysis of steroid hormones. This book is divided into nine chapters that examine the biological-clinical analysis of other important groups of steroids, including sterols, vitamin D, bile acids, cardiac glycosides, and sapogenins. The material in the book is classified according to the main groups of steroids, individual chapters being devoted to sex hormones, corticosteroids, sterols, vitamins D, bile acids, cardiac glycosides, sapogenins, and miscellaneous steroids. The structure of each chapter is the same. In section 1 the fundamentals of the chemistry of the group of steroids in question are outlined. Section 2 provides a detailed description of the use of various spectroscopic, chromatographic, protein-binding and other methods, while Section 3 deals with the main problems encountered in the analysis of the group of steroids in question and with their solution using the methods described in Section 2. This book will prove useful to steroid and analytical chemists.

The Biology of Cholesterol and Related Steroids focuses on the study of sterols in relation to living organisms. The publication first takes a look at the analysis of sterols and related steroids and the distribution of sterols and related steroids in nature, as well as the processes of extraction and separation and presence of sterols in plants, fungi, vertebrates, and invertebrates. The text then ponders on biosynthesis of sterols and metabolism of cholesterol. Topics include formation of fatty acid esters of cholesterol, steroid hormones, biosynthetic pathway to sterols, reaction mechanisms, and comparative aspects of sterol synthesis. The manuscript examines the developmental aspects of cholesterol metabolism and sterols in biological membranes. The book also reviews cholesterol synthesis in animal tissues, sterol metabolism in isolated cells, and epidemiology of the plasma cholesterol. Discussions focus on selection of statistical populations, genetic influences, regulation of sterol synthesis, general aspects of sterol metabolism, and removal of cell cholesterol in vivo. The publication is a dependable source of data for biochemists and readers interested in the biology of cholesterol and steroids.

Medicinal Chemistry, Volume 19: Quantitative Structure-Activity Relationships of Drugs is a critical review of the applications of various quantitative structure-activity relationship (QSAR) methodologies in different drug therapeutic areas and discusses the results in terms of their contribution to medicinal chemistry. After briefly describing the developments in QSAR research, this 12-chapter volume goes on discussing the contributions of QSAR methodology in elucidating drug action and rational development of drugs against bacterial, fungal, viral, and other parasitic infections of man. Other chapters explore the mode of action and QSAR of antitumor, cardiovascular, antiallergic, antiulcer, antiarthritic, and nonsteroidal antiinflammatory drugs (NSAID) agents. The discussion then shifts to the pharmacologic effects and QSAR analysis of central nervous system agents, steroids, and other hormones. A chapter examines the major chemicals affecting insects and mites, with particular emphasis on the parameters of binding correlation and reactivity for insect and mite enzymes. The concluding chapters cover the limitations of the QSAR approach in the quantitative treatment of drug absorption, distribution, and metabolism. This volume is of great value to medicinal chemists, scientists, and researchers.
