This book was released on 2024-03-20 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbohydrate Chemistry in the Total Synthesis of Naturally Occurring Glycosides Revolutionize your manufacturing processes and more with this groundbreaking introduction Carbohydrates and complex glycosides are important classes of molecules. The ubiquitous glycosides are extremely diverse in structure and functions, and many of them are of pharmacological significance. Purification of a homogeneous glycoside from the nature sources, especially in an appreciable amount, is always difficult. Chemical synthesis provides a feasible access to the homogenous glycosides and their congeners. Carbohydrate Chemistry in the Total Synthesis of Naturally Occurring Glycosides presents about 10 families of naturally occurring glycoside natural products, including about 150 molecules that organic chemists have devoted a lot of effort toward their synthesis. In each example, the background of each natural glycoside, including its natural resources, its isolation process and its bioactivities have been described; the total synthesis of the natural glycoside is presented with special emphasis on the glycosylation reaction, the strategy on saccharides assembly, the protecting group manipulation, and the method for the synthesis of the rare saccharide units. Readers can clearly see the progress of total synthesis of naturally occurring glycosides, from early to current arts, from simple to complex molecules, and from tedious strategy to highly efficient and economical methodologies in this book. It will highly benefit the further developments in the total synthesis of naturally occurring glycosides and synthetic carbohydrate chemistry. Carbohydrate Chemistry in the Total Synthesis of Naturally Occurring Glycosides is ideal for Organic Chemists, Biochemists, Pharmaceutical and Medicinal Chemists, Natural Products Chemists, and Pharmaceutical Industry

Download or read book Synthesis and Characterization of Glycosides written by Marco Brito-Arias and published by Springer Nature. This book was released on 2022-04-22 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third edition is a comprehensive and extended study about the best known approaches for preparing the main types of glycosides, covering the classic and more recent glycosylation reactions used for preparing simple and challenging glycosides currently used as potent antiviral and antineoplastic drugs, or fluorogenic substrates used for enzymatic detection in cell biology. Besides, this new edition provides more examples of the glycosidic methodologies followed for preparing complex glycoconjugates such as glycoproteins and glycosphingolipids and gangliosides used as adjuvants or as synthetic vaccines candidates. Also, additional mechanistic evidence is presented for better understanding of the glycosylation reaction, trying to identify the variables mainly depending on protecting and leaving groups, as well as catalyst and reaction condition which altogether directs the anomeric stereo control. A chapter on the glycoside hydrolysis is included in view of the increasing interest in the use of biomass as a natural and renewable source for obtaining important intermediates or products used in food or valuable materials. The author includes information in the characterization of glycosides section with the aim of giving additional tools for the structural assignment through NMR, X-Ray and mass spectra techniques.

Available in PDF, EPUB and Kindle. Book excerpt: As a reflection of the quantum leap that has been made in the study of glycostructures, the first edition of this book has been completely revised and updated. The editors give up-to-date information on glycostructures, their chemistry and chemical biology in the form of a completely comprehensive survey. Glycostructures play highly diverse and crucial roles in a myriad of organisms and important systems in biology, physiology, medicine, bioengineering and technology. Only in recent years have the tools been developed to partly understand the highly complex functions and the chemistry behind them. While many facts remain undiscovered, this MRW has been contributed to by a large number of the world’s leading researchers in the field.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers interesting research topics and the use of natural resources for medical treatments in some severe diseases. The most important message is to have native foods which contain high amount of active compounds that can be used as a medicinal plant. Most pharmaceutical drugs were discovered from plants, and still ongoing research will have to predict such new active compounds as anti-diseases. I do believe this book will add significant knowledge to medical societies as well as can be used for postgraduate students.

Download or read book Carcinogens and Anticarcinogens in the Human Diet written by National Research Council and published by National Academies Press. This book was released on 1996-03-12 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite increasing knowledge of human nutrition, the dietary contribution to cancer remains a troubling question. Carcinogens and Anticarcinogens assembles the best available information on the magnitude of potential cancer riskâ€"and potential anticarcinogenic effectâ€"from naturally occurring chemicals compared with risk from synthetic chemical constituents. The committee draws important conclusions about diet and cancer, including the carcinogenic role of excess calories and fat, the anticarcinogenic benefit of fiber and other substances, and the impact of food additive regulation. The book offers recommendations for epidemiological and diet research. Carcinogens and Anticarcinogens provides a readable overview of issues and addresses critical questions: Does diet contribute to an appreciable proportion of human cancer? Are there significant interactions between carcinogens and anticarcinogens in the diet? The volume discusses the mechanisms of carcinogenic and anticarcinogenic properties and considers whether techniques used to evaluate the carcinogenic potential of synthetics can be used with naturally occurring chemicals. The committee provides criteria for prioritizing the vast number of substances that need to be tested. Carcinogens and Anticarcinogens clarifies the issues and sets the direction for further investigations into diet and cancer. This volume will be of interest to anyone involved in food and health issues: policymakers, regulators, researchers, nutrition professionals, and health advocates.
