Steroid Chemistry At A Glance

The term steroid has become virtually synonymous with drug abuse in sport to the majority of the public. However these steroids - androgens - actually comprise only a single relatively small class of biologically active steroids, and are overshadowed by a large collection of compounds, a sizeable number of which are commercial drugs that share the same structural carbon skeleton. The development of these drugs has led to a large body of organic chemistry often denoted as "Steroid Chemistry". Steroid Chemistry At A Glance provides a concise overview of the main principles and reactions of steroid chemistry. Topics covered include: history, isolation and structure determination of steroids steroid nomenclature and stereochemistry natural sources of steroids synthesis and reactions of aromatic a-ring steroids, androstanes, and pregnanes steroids with a spirolactone at position 17 steroids with hetrocyclic ring A compounds derived from cholesterol Based on the highly successful and student friendly "at a glance" approach, the information is presented in integrated, self contained double page spreads of text and illustrative material. Students of chemistry and pharmacy using Steroid Chemistry at a Glance will find they have a resource with which they can quickly, concisely and confidently acquire, regularly review and revise the basic facts that underpin the properties, synthesis and reactions of this important class of natural products. It will also serve as a handy bench reference for postgraduates and professional chemists.

Introduction to Steroid Chemistry is a six-chapter introductory text of the analysis, conformation, and production of steroids. After providing a brief overview of steroid chemistry, this book goes on discussing the application of physical methods to the analysis of structural and stereochemical correlations in steroids, such as UV, infrared, NMR, and mass spectroscopy, optical rotary dispersion, and circular dichroism. The subsequent two chapters describe the influence of steroid conformation and molecular rearrangements on reactions rates and reaction products. The remaining chapters explore the improvements in the synthesis of the estrogenic hormones and the biosynthetic pathways and metabolism of cholesterol. This book will be of value to general and organic chemists, biochemists, and research workers in related subjects.

This expanded second edition provides a concise overview of the main principles and reactions of heterocyclic chemistry for undergraduate students studying chemistry and related courses. Using a successful and student-friendly "at a glance" approach, this book helps the student grasp the essence of heterocyclic chemistry, ensuring that they can confidently use that knowledge when required. The chapters are thoroughly revised and updated with references to books and reviews; extra examples and student exercises with answers online; and color diagrams that emphasize exactly what is happening in the reaction chemistry depicted.

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.
