Selective Estrogen Receptor Modulators Serms

The increasing awareness on the varied consequences of hypogonadism in distinct organs and systems has supported the notion of estrogens as systemic agents. This observation is congruent with the variety of tissues affected by - trogens when used in hormone therapy formulations on hypogonadic women. Apart from the genital tract and the breast, recognized as traditional targets for estrogens, the skeleton, the vascular tree, or the central nervous system, are good examples of territories that have demonstrated sensitivity to estrogens. This evidence has created great interest, as shown by the great amount of lit- ature that has been produced on the bene?ts and risks associated with the use of estrogens. In parallel to the clinical interest, basic research has improved our kno- edge on the complexities involved in estrogen action at the molecular level. Together with effects mediated through speci?c receptors, a concept that has been the mainstay of the interpretation of estrogen action for years, there is enough evidence to hold the notion of receptor-independent effects. The substantial advances in modern technology applied to research have helped in enlightening the particulars of this versatile action of estrogens. This more detailed knowledge on the sophisticated mechanism of action of estrogens has nourished the emergence of multiple hypotheses speculating with the p- sibility of manipulating estrogen action. The notion that a widely extended regulatory system of cell function, as it is the estrogen receptor machinery, might be modulated at wish has arisen as an attractive, although still elusive postulate.

Experimental and clinical researchers from a wide range of disciplines present a wealth of fresh scientific information on the biochemistry, molecular biology, pharmacology, and clinical activity of SERMs. The basic science chapters of the book focus-with an eye to the development of the ideal SERM-on the complex mechanisms of estrogen action, including ligand-dependent conformational changes in alpha and beta, and the recruitment of co-activators and co-repressors which modulate the estrogen receptor transcriptional activity and contribute to its crosstalk with growth factor signaling. The clinical presentation reviews the data accumulated on currently available SERMs, primarily tamoxifen and raloxifene, in cancer treatment and prevention, as well as their effects on the reproductive, vascular, skeletal, and central nervous systems. A tentative approach to menopause-related health issues is also provided for women with and without a previous diagnosis of localized breast cancer.

This volume presents the evolution of the authors' ideas about estrogen action and its modulation by a new group of drugs called SERMs (Selective Estrogen Receptor Modulators). The pioneering SERMs OCo tamoxifen and raloxifene OCo are known to have saved the lives of millions of women around the world and improved the health of millions more. Estrogen is the central hormone of women's health and reproduction. The book is a journey through 40 years of discovery and success in advancing women's health, with the prospect of improved innovation through medicinal chemistry for the future.

This volume examines basic and clinical findings on the role played by the oestrogen receptor (ER) and its modulation in multiple physiologic systems. The authors examine the potential of selective modification of ER actions for preventing chronic diseases and promoting healthy ageing. Research gaps and potential agendas for NIH research of ER action are identified, and related intervention strategies to extend the beneficial clinical outcomes are explored.

Written by the foremost authority in the field, this volume is a comprehensive review of the multifaceted phenomenon of hepatotoxicity. Dr. Zimmerman examines the interface between chemicals and the liver; the latest research in experimental hepatotoxicology; the hepatotoxic risks of household, industrial, and environmental chemicals; and the adverse effects of drugs on the liver. This thoroughly revised, updated Second Edition features a greatly expanded section on the wide variety of drugs that can cause liver injury. For quick reference, an appendix lists these medications and their associated hepatic injuries. Also included are in-depth discussions of drug metabolism and factors affecting susceptibility to liver injury.

Natural compounds, which have evolved their function over millions of years, are often more efficient than man-made compounds if a specific biological activity is needed, e.g. as an enzyme inhibitor or as a toxin to kill a cancer cell. This book comprising of sixteen technical chapters, highlights the chemical and biological aspects of potential natural products with an intention of unravelling their pharmaceutical applicability in modern drug discovery processes. Key features: Covers the synthesis, semi-synthesis and also biosynthesis of potentially bioactive natural products Features chemical and biological advances in naturally occurring organic compounds describing their chemical transformations, mode of actions, and structure-activity relationships 40 expert scientists from around the world report their latest findings and outline future opportunities for the development of novel and highly potent drugs based on natural products operating at the interface of chemistry and biology Forward-looking: Addresses opportunities and cutting-edge developments rather than well-documented basic knowledge, pinpoints current trends and future directions in this rapidly-evolving field Application-oriented: Throughout the book, the focus is on actual and potential applications in pharmacology and biotechnology This book is an essential resource for natural products chemists, medicinal chemists, biotechnologists, biochemists, pharmacologists, as well as the pharmaceutical and biotechnological industries.

This edited book describes what fragile bone is, how the condition is assessed, and how it can be treated. It is intended for multi-professional trainees and practitioners in health and social care fields who care for and treat the elderly. Chapters within the book provide the latest advances in cell and molecular biology, morphology, radiology, and the biomechanics of bone in health and disease. The basic concept of “Remodeling” and “Modeling” is described for better understanding of the mechanisms of osteoporosis. Methods of identifying and assessing osteoporosis are described, as are risk factors for bone fracture and non-unions. Furthermore, the effects of various drugs used to treat osteoporosis at both material and structural levels of bone and their cost effectiveness are described. Operative treatments for fracture that maintain or improve the quality of life of patients are included Treatment of Osteoporotic Fracture and Systemic Skeletal Disorders attempts to provide a holistic and translational view of the pathogenesis and treatment of osteoporosis and some other musculoskeletal diseases, with an overview of treatment modalities in various clinical settings.
