Download or read book Iminosugars written by Philippe Compain and published by John Wiley & Sons. This book was released on 2007-10-22 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iminosugars form undoubtedly the most attractive of carbohydrate mimics reported so far. In these structures, the substitution of the endocyclic oxygen of sugars by a basic nitrogen atom leads to remarkable biological properties and raises many challenges in organic synthesis. Since the discovery of their biological activity as glycosidase inhibitors in the 1970’s, these polyvalent molecules have progressively made their way from the laboratory to the clinic. The impressive series of discoveries in the field over the past ten years indicates clearly that it is “a boom time” for iminosugar chemistry and biology. The scope of their profile as inhibitors has been extended to a number of enzymes such as phosphorylases, glycosyltransferases or metalloproteinases, and iminosugars now constitute lead compounds for the development of new therapeutic agents for a wide range of diseases including diabetes, viral infections, lysosomal storage disorders and tumor metastasis. Latest developments, from iminosugar synthesis to their use in clinical studies, are presented in this book, which contains contributions from over fifteen of the major chemists, biochemists and drug developers in this rapidly expanding field. An extensive table correlating the structures of more than 600 iminosugars of therapeutic interest with their biological activities is also included in the book and should prove particularly useful to aid with the design and the discovery of novel bioactive substances. Iminosugars: From Synthesis to Therapeutic Application provides a unique resource for academic and industrial researchers working in the field of iminosugars and glycomimetics of biological and/or therapeutic interest: organic chemists, medicinal chemists, carbohydrate chemists and medical scientists.
Download or read book Iminosugars as Glycosidase Inhibitors written by Arnold E. Stütz and published by Wiley-VCH. This book was released on 1999-01-21 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iminosugars as Glycosidase Inhibitors Nojirimycin and Beyond Edited by Arnold E. Stutz "Nowadays as a result of these manifold synthetic efforts a large number of inhibitors are available, that can be applied selectively for many different glycosidases. They are important aids to explain the construction and degradation particularly of complex carbohydrate side chains such as those found in glycoproteins and glycolipids. The amount of chemical and biochemical information has meanwhile grown to such an extent that it is almost impossible to keep track of the developments. Therefore it is particularly pleasing that contributions from experts for the individual fields are collected together in one work, thus providing a comprehensive overview. In this way this book gives a representative cross-section of the field. The book will be a generally interesting source of information for chemists and biochemists." (From the foreword by H. Paulsen). A table which lists over 400 glycosidase inhibitors, more than 200 enzymes with 323 citations and over 1500 invaluable sets of data completes the book.
Download or read book Carbohydrates 2018 written by Amélia Pilar Rauter and published by MDPI. This book was released on 2020-03-25 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains original papers and reviews on carbohydrate research in medicine, authored by participants of the 29th International Carbohydrate Symposium, where this topic had a special emphasis. The focus on biological events involving carbohydrates and glycoconjugates has delivered reliable approaches for disease treatment and diagnosis. Research on carbohydrate-based compounds for therapeutic applications is illustrated in various contributions, namely those covering the development of novel agents against Alzheimer’s disease, e.g. the neuroprotective C-glucosylated flavones and the isonucleoside-based cholinesterase inhibitors. New imino sugar glucosidase inhibitors are also disclosed, a class of compounds with potential for diabetes, Gaucher disease or cancer treatment. Also the development of a useful synthetic method towards multivalent glycoclusters of biomedical interest is here highlighted. The relevance of glycomimetics in drug discovery and the progress on carbohydrates in early diagnosis and cancer treatment are reviewed. Noteworthy is the chitosan-based delivery system for drug oral administration, a new biomaterial-based approach to improve bioavailability. Another study on the conformation of Streptococcus capsular polysaccharide backbones by molecular modelling provides useful information for bacterial immunotherapeutic approaches. All original contributions and reviews clearly demonstrate the potential of glycosciences for innovation in medicinal (glyco)chemistry and pharmaceutical research.

Download or read book Handbook of Glycosyltransferases and Related Genes written by Naoyuki Taniguchi and published by Springer Science & Business Media. This book was released on 2011-06-28 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: The so-called postgenomic research era has now been launched, and the field of gly cobiology and glycotechnology has become one of the most important areas in life science because glycosylation is the most common post-translational modification reaction of proteins in vivo. On the basis of Swiss-Prot data, over 50% proteins are known to undergo glycosylation, but in fact the actual functions of most of the sugar chains in the glycoconjugates remain unknown. The complex carbohydrate chains of glycoproteins, glycolipids, and proteoglycans represent the secondary gene products formed through the reactions of glycosyl transferases. The regulation of the biosynthesis of sugar chains is under the control of the expression of glycosyltransferases, their substrate specificity, and their local ization in specific tissue sites. There is a growing body of evidence to suggest that these enzymes play pivotal roles in a variety of important cellular differentiation and developmental events, as well as in disease processes. Over 300 glycosyltransferases appear to exist in mammalian tissues. If the genes that have been purified and cloned from various species such as humans, cattle, pigs, rats and mice are counted as one, approximately 110 glycogenes that encode glycosyltransferases and related genes have been cloned at present, and this number continues to grow each day. However, most of the functions of the glycosyltransferase genes and related genes are unknown. This fact has stimulated numerous new and interesting approaches in molecular biologi cal investigations.

Download or read book Carbohydrate spiro heterocycles written by László Somsák and published by Springer Nature. This book was released on 2019-10-26 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is devoted to compounds in which the spiro centre is part of a pyranoid or furanoid or an iminosugar ring. The chapters contributed deal with methodological peculiarities of syntheses of natural and artificial sugar derived spirocycles as well as their biological applications and other utilities including marketed drugs. Carbohydrates are ubiquitous molecules in nature and participate in a vast number of biological interactions. Especially their conjugates with practically all kinds of primary and secondary metabolic small molecules (and also biomacromolecules) representing valuable tools for glycobiology research and also lead compounds for drug discovery. While monosaccharides per se appear as heterocycles, their natural conjugates frequently exhibit spiro(hetero)cyclic derivatives, in many cases of high therapeutical relevance. As a consequence, the field of carbohydrate-spiro-heterocycles attracts intense interest from both chemical and biomedical aspects therefore this volume will be of interest for synthetic and medicinal chemists and (glyco)biologists, as well as researchers involved in various biomedical fields.
