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.

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.

Natural products present in the plant and animal kingdom offer a huge diversity of chemical structures, which are the result of biosynthetic processes that have been modulated over the millennia through genetic effects. With the rapid developments in spectroscopic techniques and accompanying advances in high-throughput screening techniques, it has become possible to isolate and then determine the structures and biological activity of natural products rapidly, thus opening up to the pharmaceutical industry exciting opportunities in the field of new drug development. The series covers all of the above as well as the synthesis, testing and recording of the medicinal properties of natural products. With articles written by leading authorities in their respective fields of research, Studies in Natural Products Chemistry, Volume 46 presents current frontiers and future guidelines for research based on important discoveries made in the field of bioactive natural products. It is a valuable resource for all those working in natural product and medicinal chemistry. Focuses on the chemistry of bioactive natural products Contains contributions by leading authorities in the field Presents sources of new pharmacophores

From cooking to medicine, from engineering to art, chemistry—the science of molecules—is everywhere. A celebration of the molecules of chemistry, Every Molecule Tells a Story celebrates the molecules responsible for the experiences of everyday life: the air we breathe; the water we drink; the chemicals that fuel our living; the steroids that give us sex; the colours of the seasons; the drugs that heal us; and the scented molecules that enrich our diet and our encounters with each other. You can’t see them, but you know that they are there. Unveiling the structures of poisonous "natural" substances and beneficial man-made molecules, this book brushes away any preconceived notions about chemistry to demonstrate why and how molecules matter.

Bioactive compounds play a central role in high-value product development in the chemical industry. Bioactive compounds have been identified from diverse sources and their therapeutic benefits, nutritional value and protective effects in human and animal healthcare have underpinned their application as pharmaceuticals and functional food ingredients. The orderly study of biologically active products and the exploration of potential biological activities of these secondary metabolites, including their clinical applications, standardization, quality control, mode of action and potential biomolecular interactions, has emerged as one of the most exciting developments in modern natural medicine. Biotechnology of Bioactive Compounds describes the current stage of knowledge on the production of bioactive compounds from microbial, algal and vegetable sources. In addition, the molecular approach for screening bioactive compounds is also discussed, as well as examples of applications of these compounds on human health. The first half of the book comprises information on diverse sources of bioactive compounds, ranging from microorganisms and algae to plants and dietary foods. The second half of the book reviews synthetic approaches, as well as selected bioactivities and biotechnological and biomedical potential. The bioactive compounds profiled include compounds such as C-phycocyanins, glycosides, phytosterols and natural steroids. An overview of the usage of bioactive compounds as antioxidants and anti-inflammatory agents, anti-allergic compounds and in stem cell research is also presented, along with an overview of the medicinal applications of plant-derived compounds. Biotechnology of Bioactive Compounds will be an informative text for undergraduate and graduate students of bio-medicinal chemistry who are keen to explore the potential of bioactive natural products. It also provides useful information for scientists working in various research fields where natural products have a primary role.
