Available in PDF, EPUB and Kindle. Book excerpt: Pyridines: From Lab to Production provides a synthetic armory of tools to aid the practicing chemist by reviewing the most reliable historical methods alongside new methods/ Written by scientists who have actually used these in synthesis. By emphasizing tricks and tips to optimize reactions for the best yields and purity, which are often missing from the primary literature, this book provides another dimension for the synthetic chemist. A combined academic and industrial approach evaluates the best methods for different scales of reaction and discusses practical tips (e.g. when to stop a reaction early to maximize purity or when to re-use side products). Chapters also assess whether to make or source starting materials, how to connect them and what are the best synthetic routes. The book is designed to be a stand-alone reference, but also provides cross references to leading reviews and the Comprehensive Heterocyclic Chemistry reference works for those who want to learn more. Reviews tried and tested practical methods to help the reader select the best method for their research Includes tips, tricks and hints to enable the reader to get the best yield or cleanest product out of their reaction for synthesising or transforming a pyridine derivative Written by both academic researchers and industry leaders this provides a unique view of how to get the most out of a reaction no matter what scale you are running this on

Download or read book Metal Ions in Biochemistry written by Pabitra Krishna Bhattacharya and published by CRC Press. This book was released on 2020-12-13 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Metal Ions in Biochemistry deals with the multidisciplinary subject of bio-inorganic chemistry, encompassing the disciplines of inorganic chemistry, biochemistry and medicine. The book deals with the role of metal ions in biochemistry, emphasising that biochemistry is mainly the chemistry of metal-biochemical complexes. Hence, the book starts with the structures of biochemicals and the identification of their metal binding sites. Thermodynamic and kinetic properties of the complexes are explained from the point of view of the nature of metal-ligand bonds. Various catalytic and structural roles of metal ions in biochemicals are discussed in detail. Features The role of Na+ and K+ in brain chemistry. The role of zinc insulin in glucose metabolism and its enhancement by vanadium and chromium compounds. Discussion of the role of zinc signals, zinc fingers and cascade effect in biochemistry. Haemoglobin synthesis and the role of vitamin B12 in it. The role of lanthanides in biochemical systems. A detailed discussion of the role of non-metals in biochemistry, a topic missing in most of the books on bio-inorganic chemistry. The study of bio-inorganic chemistry makes biochemists rethink the mechanistic pathways of biochemical reactions mediated by metal ions. There is a realisation of the role of metal complexes and inorganic ions as therapeutics such as iron in leukaemia, thalassemia and sickle cell anaemia, iodine in hypothyroidism and zinc, vanadium and chromium in glucose metabolism. The most recent realisation is of the use of zinc in the prevention and treatment of COVID-19.

Download or read book Comprehensive Enantioselective Organocatalysis written by Peter I. Dalko and published by John Wiley & Sons. This book was released on 2013-08-14 with total page 1499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Structured in three parts this manual recollects efficient organocatalytic transformations around clear principles that meet actual standard in asymmetric synthesis. Chapters were written by acknowledged leaders of the organocatalysis field, and are presented in a concise way. Volume 1: Privileged Catalysts gives insight to readers to the continuously increasing variety of catalysts, and the relatively complex interactions that make organocatalytic reactions selective. An appendix recollects catalyst structures with the adequate cross-references. Volume 2: Activations covers the fundamental activation types (non-covalent and covalent activations) and helps understanding the importance of physical parameters, and in particular, the role of water, that influences reactivity and selectivity. Volume 3: Reactions and Applications highlights transformations by reaction types. The final part of this volume is dedicated to application in multistep synthesis and industrial applications. Considering the ever increasing interest in the organocatalysis field, the book aims addressing to a large audience: to academic, and, industrial researchers, students and teachers who are interested in synthetic organic chemistry at advanced level. This book provides non-specialists with an introduction to the topic as well as serving as a valuable source for newcomers and researchers searching for an up-to-date and comprehensive overview of this promising area of synthetic organic chemistry.

Download or read book A Paradigm Shift to Prevent and Treat Alzheimer s Disease written by Howard Friel and published by Academic Press. This book was released on 2017-07-18 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Paradigm Shift to Prevent and Treat Alzheimer’s Disease: From Monotargeting Pharmaceuticals to Pleiotropic Plant Polyphenols is the first book to systematically exhibit the powerful pleiotropic pharmacological effects on Alzheimer’s disease of plant-based compounds from ancient foods that humans have been consuming safely with substantial health benefits for thousands of years. These plant-based compounds include curcuminoids from turmeric, resveratrol from red wine and grape seed extract from other grape products, epigallocatechin-gallate (EGCG) from green tea, and oleocanthal and oleuropein from olive oil, in addition to a special extract, EGb 761, from the leaves of Ginkgo biloba, the oldest living species of tree on earth. This book also presents a new analytical framework that convincingly favors a multi-targeting ("pleiotropic") approach to the prevention and treatment of complex chronic diseases, in contrast to the mono-targeting of the pharmaceutical model. A Paradigm Shift to Prevent and Treat Alzheimer’s Disease is a unique and exciting resource for pharmaceutical scientists, pharmacologists, neurologists, general practitioners, research scientists in various medical and life sciences, healthcare professionals in clinical and executive positions, conventional medical schools, schools of naturopathic medicine, healthcare and medical journalists, executives in both national public healthcare systems and private insurers, and informed general readers. Presents carefully compiled evidence supporting the need to shift from pharmaceutical-based mono-targeting to plant polyphenol-based pleiotropic targeting for the prevention and treatment of Alzheimer’s disease Includes valuable tables that aggregate pleiotropic pharmacological effects of the plant polyphenols on Alzheimer’s disease-related pathogenic hallmarks Highlights regulatory aspects and discusses the challenges and potential solutions with respect to bioavailability of certain plant polyphenols
