This book was released on 2020-03-27 with total page 1046 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive experimentation and high failure rates are a well-recognised downside to the drug discovery process, with the resultant high levels of inefficiency and waste producing a negative environmental impact. Sustainable and Green Approaches in Medicinal Chemistry reveals how medicinal and green chemistry can work together to directly address this issue. After providing essential context to the growth of green chemistry in relation to drug discovery in Part 1, the book goes on to identify a broad range of practical methods and synthesis techniques in Part 2. Part 3 reveals how medicinal chemistry techniques can be used to improve efficiency, mitigate failure and increase the environmental benignity of the entire drug discovery process, whilst Parts 4 and 5 discuss natural products and microwave-induced chemistry. Finally, the role of computers in drug discovery is explored in Part 6. - Identifies novel and cost effective green medicinal chemistry approaches for improved efficiency and sustainability - Reflects on techniques for a broad range of compounds and materials - Highlights sustainable and green chemistry pathways for molecular synthesis

Their contributions demonstrate the rapid, ongoing development of this field by illustrating many of the latest advances in synthetic methods, total synthesis, structure determination, biosynthetic pathways, and biological activity.The opening chapter presents an overview of strategies for the synthesis of several classes of natural products with an emphasis on complex polycyclic systems. Subsequent chapters discuss the synthesis of specific classes of compounds, including morphine, polyketides, acetogenins, nonactic acid derivatives, complex spirocyclic ethers, ä-lactam and pyridone derivatives, inositol phosphates, sphingolipids, brassinosteroids, Hernandia lignans, and dimeric steroidal pyrazine alkaloids. Finally, the ever stronger links between chemistry and biology are reinforced by chapters on the origin and function of secondary metabolites, bioactive conformations of gastrin hormones, and immunochemistry.
Download or read book Steroids in Brain Function written by Cristin Roth and published by American Medical Publishers. This book was released on 2023-09-26 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A steroid is an organic molecule having four rings organized in a specific molecular configuration that is biologically active. Steroids serve two principal biological functions. First, they are important components of cell membranes that affect membrane fluidity. Second, they act as signaling molecules. Animals, plants, and fungi all contain hundreds of steroids. Steroid hormones influence metabolism and the biological processes. These hormones affect endocrine functions such as sexual differentiation and reproductive life. The pharmaceutical industry has used steroids for making anticancer, anti-inflammatories, anticonvulsants, contraceptives, and fertility drugs. Steroid dimers are a class of chemicals that are produced by a variety of marine creatures and can also be manufactured in laboratories. This class of compounds has a wide range of pharmacological and biological properties, and can be utilized to make molecular umbrellas for drug delivery. This book explores all the important aspects of steroids in the present-day scenario. It is a valuable compilation of topics, encompassing their chemistry as well as applications in drug design and delivery. This book is a vital tool for all researching or studying steroids.

Download or read book Animal Cell Biotechnology written by Raymond Spier and published by Academic Press. This book was released on 1994-11-14 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a dramatic increase in the perception of the value of animal cell biotechnology to the research and manufacturing communities in recent years. This volume seeks to keep the reader up-to-date with this progress. This sixth and final volume in the series concentrates on the biology of animal cells in culture, giving special attention to the relationship between biology and the ability to use such cells productively. As the search continues for greater productivity, there is a need to understand the switches within cells that control expression. Additional abilities to manipulate those switches in a controllable manner are also required. In the last five years, considerable progress has been made in the elucidation of the mechanisms for cell signaling and control of gene expression. The 13 chapters of this volume are devoted to these subjects and to techniques in areas of particular concern in manufacturing circles. The achievements in the field to date are described in this book, which, together with its five companion volumes in the series, will provide a building block for the future development of animal cell biotechnology.
