The interactions between carbohydrates and proteins have been extensively explored in a wide range of physiological and pathological processes over several decades. The recent emergence of glycomics has strengthened this interest and notably contributed t
Abstract: We engineered the first chimeric, bispecific lectin, with two rationally oriented and distinct recognition surfaces. This lectin, coined Janus lectin in allusion to the two-faced roman god, is able to bind independently to both fucosylated and sialylated glycoconjugates. The multivalent presentation of binding sites on each face of the Janus lectin is very efficient, resulting in avidities in the low nanomolar range for both fucosylated and sialylated surfaces. Moreover, novel heterovalent, bifunctional glycoclusters were synthetized that match the topology of the Janus lectin. Based on these tools, we constructed organized and controlled supramolecular architectures by assembling Janus lectin and glycocompound layer-by-layer. Furthermore, the Janus lectin was employed as biomolecular linker to organize protocells made from giant unilamellar vesicles of different nature, to more complex prototissues. In summary, tailor-made Janus lectins open wide possibilities for creating biomimetic matrices or artificial tissues
Carbohydrate Chemistry is an invaluable volume demonstrating the interdisciplinary nature of modern carbohydrate research and containing analysed, evaluated and distilled information on the latest research in the area.
The second volume in the series Carbohydrate Chemistry: Proven Synthetic Methods, Volume 2 offers a collection of synthetic procedures valuable to the practice of synthetic carbohydrate chemistry. The series takes an important and unique approach in that all described procedures have been independently verified as reliable and reproducible. With editors and contributors who are highly respected scientists in the field, this book provides a widely useful reference for both researchers and students, exploring carbohydrate chemistry from both academic and industrial points of view. The book begins with an introductory section that offers tricks and tips collected by the series editor from many ...
conjugate biomaterials have profoundly impacted the medical field. --
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 ...
The structural complexity and the synthetic challenges facing glycans have historically hampered efforts to study their multifaceted roles and the application of carbohydrates in drug development. However, in very recent years, new synthetic techniques flanked by the growing knowledge about carbohydrate involvement in physiological and pathological states has spurred renewed interest in the chemistry, biology and therapeutic potentialities of carbohydrates. This book offers an overview of key aspects of carbohydrate biology and chemistry that are fundamental for the design of novel therapeutics. The four-part structure of this book introduces these essential components to life, starting from...
