Carbohydrate Chemistry


Book Description

Volumes in the Proven Synthetic Methods Series address the concerns many chemists have regarding irreproducibility of synthetic protocols, lack of identification and characterization data for new compounds, and inflated yields reported in chemical communications—trends that have recently become a serious problem. Featuring contributions from world-renowned experts and overseen by a highly respected series editor, Carbohydrate Chemistry: Proven Synthetic Methods, Volume 4 compiles reliable synthetic methods and protocols for the preparation of intermediates for carbohydrate synthesis or other uses in the glycosciences. Exploring carbohydrate chemistry from both the academic and industrial points of view, this unique resource brings together useful information into one convenient reference. The series is unique among other synthetic literature in the carbohydrate field in that, to ensure reproducibility, an independent checker has verified the experimental parts involved by repeating the protocols or using the methods. The book includes new or more detailed versions of previously published protocols as well as those published in not readily available journals. The essential characteristics of the protocols presented are reliability, updated characterization data for newly synthesized substances and the expectation of wide utility in the carbohydrate field. The protocols presented will be of wide use to a broad range of readers in the carbohydrate field and the life sciences, including undergraduates taking carbohydrate workshops.

Carbohydrate Chemistry


Book Description

Long gone are the days when synthetic publications included parallel preparative experiments to document reproducibility of the experimental protocols and when journals required such documentation. The new Proven Synthetic Methods Series addresses concerns to chemists regarding irreproducibility of synthetic protocols, lack of characterization data for new compounds, and inflated yields reported in many chemical communications—trends that have recently become a serious problem. Volume One of Carbohydrate Chemistry: Proven Synthetic Methods includes more detailed versions of protocols previously published for the synthesis of oligosaccharides, C-glycosyl compounds, sugar nucleotides, click chemistry, thioglycosides, and thioimidates, among others. The compilation of protocols covers both common and less frequently used synthetic methods as well as examples of syntheses of selected carbohydrate intermediates with general utility. The major focus of this book is devoted to the proper practice of state-of-the-art preparative procedures, including: References to the starting materials used, reaction setup, work-up and isolation of products, followed by identification and proof of purity of the final material General information regarding convenience of operation and comments on safety issues Versatile and practically useful methods that have not received deserved, long-lasting recognition or that are difficult to access from their primary sources Copies of 1D NMR spectra of compounds prepared, showing purity of materials readers can expect Exploring carbohydrate chemistry from the academic points of view, the Carbohydrate Chemistry: Proven Synthetic Methods Series provides a compendium of preparatively useful procedures checked by chemists from independent research groups.




Carbohydrates 2018


Book Description

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.
