DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKThe 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.

DOWNLOAD EBOOKThis book presents an authoritative review of the research regarding the influences of anabolic-androgenic steroids on metabolism. The book provides a concise description of the biochemistry of these steroids using simple terms and includes methods of separation and their clinical applications. The first section of the book examines the general structure, nomenclature, and classification of anabolic-androgenic steroids. Subsequent chapters explore concepts basic to understanding the pathways of their metabolism in both target and non-target tissues, including the interactions of steroids with receptors and the effects of steroids on the cellular metabolism of skeletal muscle. The changes and molecular base of modifications in metabolism during exercise involving anabolic-androgenic steroids are also described. Finally, a comprehensive review of methods for scanning and identifying anabolic-androgenic steroids in biological fluids is presented, as well as a discussion regarding the applicability and limitations of these techniques. The book provides valuable reference information for all scientists and clinicians engaged in sports medicine, exercise biochemistry, and endocrinology.
Steroid-protein Interactions

DOWNLOAD EBOOKThis is the story of steroid-protein interactions as one investigator sees it. Following the general concept of this monograph series, it emphasizes the results and interpretations obtained in the author's laboratory, and is therefore a subjective account. Recognizing, how ever, that the discussion of the subject would be incomplete if the material were limited to one scientist's work, the essential achieve ments of other investigators have been incorporated. An effort has thus been made to give a balanced presentation and to enable the reader to see in perspective the varied facets of the interactions between steroids and proteins. Since this is the first comprehensive treatment of the topic, it seems appropriate to go to the roots, and try to find out how it all started. The first chapters, therefore, take the reader to the laboratories of those who very early conceived the significance of the attachment of dyes, drugs, and other conspicuous molecules to those colloids called proteins. The discovery of the steroid hormones set the stage for meaningful investigation of their interaction with proteins of various origins and functions - a process which is continuing today with increasing vigor.

DOWNLOAD EBOOKSince 1982, our ever-expanding group of investigators has been meeting in exotic parts of the world to discuss aspects of three enzyme systems. The 1996 meeting was no exception. Nearly 90 scientists from 15 countries met in the small city of Deadwood, South Dakota, for four days of stimulating talks and posters and incredible scenery. Once more this meeting reflected the changing trends in biochemical research. At the 1982 meeting most of the speakers discussed isolating new enzymes and trying to characterize them. At this meeting many speakers discussed interpretations of three-dimensional struc ture or regulatory elements of the genes controlling for the tissue-specific expression of the enzyme. Hopefully, readers will find the proceedings of the meeting to be of interest. Though they reflects the scientific information that was presented at the meeting, they do not indicate the level of personal interactions that went on during the meeting. Once again, the willingness of the participants to discuss unpublished data and to share thoughts about the future directions of their research helped make this, like our previous seven meetings, a special scientific experience for those who attended.

DOWNLOAD EBOOKThis volume provides comprehensive coverage of the current knowledge of the physiology of the endocrine system and hormone synthesis and release, transport, and action at the molecular and cellular levels. It presents essential as well as in-depth information of value to both medical students and specialists in Endocrinology, Gynecology, Pediatrics, and Internal Medicine. Although it is well established that the endocrine system regulates essential functions involved in growth, reproduction, and homeostasis, it is increasingly being recognized that this complex regulatory system comprises not only hormones secreted by the classic endocrine glands but also hormones and regulatory factors produced by many organs, and involves extensive crosstalk with the neural and immune system. At the same time, our knowledge of the molecular basis of hormone action has greatly improved. Understanding this complexity of endocrine physiology is crucial to prevent endocrine disorders, to improve the sensitivity of our diagnostic tools, and to provide the rationale for pharmacological, immunological, or genetic interventions. It is such understanding that this book is designed to foster.
