Available in PDF, EPUB and Kindle. Book excerpt: Molecular Structure and Biological Activity of Steroids focuses on the indentification of steroid structural features that control particular biological effects. Steroid geometry plays a critical role in steroid activity; therefore, the results of X-ray crystallographic, NMR spectroscopic, and theoretical studies on structure-activity relationships form an integral part of the book. Well-established observations and proposed models are presented, summarizing knowledge of molecular features (e.g., steroid backbone structures, side-chain constitutions, substitution sites, configurations, hydrogen-bonding patterns) that can affect steroid action. The book also provides overviews about recent progress in various frontier fields of steroid research, including such areas as sex steroids, glucocorticoids, aromatase inhibitors, vitamin D metabolites, brassinosteroids, neuromuscular blocking agents, and cardiotonic steroids. Molecular Structure and Biological Activity of Steroids is a "must-have" resource for biochemists, pharmacologists, endocrinologists, biophysicists, and others actively involved in steroid research.

Download or read book Principles of Endocrinology and Hormone Action written by Antonino Belfiore and published by Springer. This book was released on 2018-02-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-03-09 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in basic biological research have proceeded rapidly in recent years. The fields of molecular genetics and immunology have experienced dramatic breakthroughs, capturing the imagination of both the scientific community and the general public. With less public notice, receptor biology has brought a cascade of new discoveries and insights. The entire science of pharmacology has been virtually rewritten in terms of receptor phenomenology. In particular, the discovery of specific receptors for steroid and protein hormones has been of seminal importance. With this new information, we have advanced our understanding of the mechanism and specifity of hormone action. We can now explain how hormones interact selectively with specific target cells and how hormones alter biochemical events within the target cells. These facts have already impacted on applied problems of clinical medicine, particularly in diagnosis and treatment of cancer and some metabolic diseases. Now, a new and important application of basic receptor biology and chemistry looms ahead. Within a few short years since the discovery of the progesterone receptor, chemists have synthesized molecules with a greater affinity for the receptor than progesterone itself and which, while occupying the receptor, fail to trigger the events which transform a target cell from the unstimulated to the stimulated state. This is the basis of the competitive inhibitory action of the anti-progestational agent, synthesized by the chemists at Roussel Uc1af, Paris, and designated RU 486.

Download or read book Hormones written by Anthony W. Norman and published by Academic Press. This book was released on 2014-06-28 with total page 823 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hormones provides a comprehensive treatment of human hormones viewed in the light of modern theories of hormone action and in the context of current understanding of subcellular and cellular architecture and classical organ physiology. The book begins with discussions of the first principles of hormone action and the seven classes of steroid hormones and their chemistry, biosynthesis, and metabolism. These are followed by separate chapters that address either a classical endocrine system, e.g., hypothalamic hormones, posterior pituitary hormones, anterior pituitary hormones, ,thyroid hormones, pancreatic hormones, gastrointestinal hormones, calcium regulating hormones, adrenal corticoids, hormones of the adrenal medulla, androgens, estrogens and progestins, and pregnancy and lactation hormones; or newer domains of hormone action which are essential to a comprehensive understanding of hormone action, including prostaglandins, thymus hormones, and pineal hormones. The book concludes with a presentation of hormones of the future, i.e., cell growth factors. This book is intended for use by first-year medical students, graduate students, and advanced undergraduates in the biological sciences. It is also hoped that this book will fill the void that exists for resource materials for teaching cellular and molecular endocrinology and that it will be employed as an equal partner with most standard biochemistry textbooks to provide a comprehensive and balanced coverage of this realm of biology.
