Book Description
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.

Book Description
The steroid scaffold continues to be the structural basis of new drugs for a variety of targets and diseases. Indeed, steroids interact with enzymes and receptors in a strikingly specific manner. Chemistry and Biological Activity of Steroids aims to provide an updated overview of recent advances in the medicinal chemistry of steroids. Novel synthetic methods in the steroids field, including steroid biotransformations, new steroids able to tackle steroid receptors, and steroid enzymes with clinical relevance, are critically reviewed in this book. Furthermore, the diverse physiopathological roles of oxysterols and their therapeutic value are also discussed.

Book Description
This book provides a broad reference covering important drugs of abuse including amphetamines, opiates, and steroids. It also covers psychoactive plants such as caffeine, peyote, and psilocybin. It provides chemical structures, analytical methods, clinical features, and treatments of these drugs of abuse, serving as a highly useful, in-depth supplement to a general medical toxicology book. The style allows for the easy application of the contents to searchable databases and other electronic products, making this an essential resource for practitioners in medical toxicology, industrial hygiene, occupational medicine, pharmaceuticals, environmental organizations, pathology, and related fields.

Book Description
Doping, Performance-Enhancing Drugs, and Hormones in Sport: Mechanisms of Action and Methods of Detection examines the biochemistry and bioanalytical aspects of performance-enhancing drugs (PEDs) and other questionable procedures used by athletes to enhance performance. The book informs the specialist of emerging knowledge and techniques and allows the non-specialist to grasp the underlying science and current practice of the discipline. With clear and compelling language appropriate for a broad spectrum of readers, this book provides background on prevalence, types of agents, their actual or supposed benefits, and their negative effects on health. The technical aspects of detection are discussed, followed by a discussion of why detection is a problematic and still-evolving science. To facilitate comprehension, each chapter is organized in a uniform way with six sections: (1) standard medical uses, (2) why the drugs are used by athletes, (3) biological mechanism of action, (4) what research says about efficacy in improving performance, (5) major health side effects from use and abuse in sport, and 6) concluding key points. - Presents the scientific concepts of how performance enhancers work, how they are used, and how they are detected and masked from detection - Features language that is neither simplistic to scientists nor too sophisticated for a large, diverse global audience - Provides a short "close-up in each chapter to illustrate key topics that engage, entertain, and create a novel synthesis of thought

Book Description
Synthesis of Essential Drugs describes methods of synthesis, activity and implementation of diversity of all drug types and classes. With over 2300 references, mainly patent, for the methods of synthesis for over 700 drugs, along with the most widespread synonyms for these drugs, this book fills the gap that exists in the literature of drug synthesis. It provides the kind of information that will be of interest to those who work, or plan to begin work, in the areas of biologically active compounds and the synthesis of medicinal drugs. This book presents the synthesis of various groups of drugs in an order similar to that traditionally presented in a pharmacology curriculum. This was done with a very specific goal in mind – to harmonize the chemical aspects with the pharmacology curriculum in a manner useful to chemists. Practically every chapter begins with an accepted brief definition and description of a particular group of drugs, proposes their classification, and briefly explains the present model of their action. This is followed by a detailed discussion of methods for their synthesis. Of the thousands of drugs existing on the pharmaceutical market, the book mainly covers generic drugs that are included in the WHO's Essential List of Drugs. For practically all of the 700+ drugs described in the book, references (around 2350) to the methods of their synthesis are given along with the most widespread synonyms. Synthesis of Essential Drugs is an excellent handbook for chemists, biochemists, medicinal chemists, pharmacists, pharmacologists, scientists, professionals, students, university libraries, researchers, medical doctors and students, and professionals working in medicinal chemistry. * Provides a brief description of methods of synthesis, activity and implementation of all drug types* Includes synonyms* Includes over 2300 references

Book Description
Steroid dimers are an important group of compounds produced by various marine organisms, and also synthesized in the laboratories. This group of compounds possesses various pharmacological and biological properties, and can also be used to create “molecular umbrellas” for drug delivery. Steroid Dimers: Chemistry and Applications in Drug Design and Delivery provides an up-to-date overview on the chemistry and applications of steroid dimers of natural and synthetic origins. The book includes easy-to-follow synthetic protocols for various classes of important dimeric steroids, source details, valuable spectroscopic data and depiction of unique structural features of natural steroidal dimers, and the Structure-Activity-Relationships (SARs) of some pharmacologically active dimeric steroids. Topics covered include: introduction to steroid dimers synthesis and chemistry of noncyclic and cyclic steroid dimers naturally occurring steroid dimers – cephalostatins, ritterazines and crellastatins biological and pharmacological functions of steroid dimers and their application in drug design and discovery steroid dimers as “molecular umbrellas” for drug delivery Steroid Dimers: Chemistry and Applications in Drug Design and Delivery is an essential guide to this important class of natural and synthetic compounds for researchers and students of natural products chemistry and biochemistry, synthetic organic and medicinal chemistry, and drug design, discovery and delivery.
