Download or read book Chemical Probes of Dendritic Cell C-type Lectin Receptors written by and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dendritic cells (DCs) are professional antigen-presenting cells that possess the unique ability to induce primary immune responses. They directly capture invading pathogens and transmit danger signals to the adaptive immune system, which ultimately initiates a robust immune response. DCs sense invading pathogens through an arsenal of receptors that recognize highly conserved, pathogenic epitopes. These receptors include C-type lectin receptors (CLRs) that bind to pathogenic glycans to facilitate pathogen uptake and degradation. In addition, CLRs also complex host glycans to mediate DC locomotion and cell-cell communication. Despite a clear importance in immunity, many CLRs are exploited by pathogens for nefarious purposes. For example, DC-SIGN is co-opted by pathogens, including HIV-1 and Mycobacterium tuberculosis, to facilitate infection and dissemination. However, the mechanisms that pathogens use to exploit DC-SIGN remain poorly understood. This thesis describes strategies for ligand synthesis that can afford probes of DC-SIGN function. These strategies can be generalized and applied to any CLR of interest. In light of emerging evidence that glycan structure may affect CLR function, I designed polymers bearing pendant carbohydrates (glycopolymers) to function as glycan surrogates. By employing glycopolymers of defined composition, we observed that glycopolymer valency affects both DC-SIGN-mediated internalization and trafficking within the cell. Studying CLRs is challenging due to their overlapping ligand specificities. To target DC-SIGN, we previously generated non-carbohydrate glycomimetics from (--)-shikimic acid that mimic the DC-SIGN ligand, D-mannose. By expanding this approach, I have demonstrated that these compounds can be converted into probes that elicit DC-SIGN function (e.g. internalization, signaling). Moreover, I have developed a divergent synthetic route to non-natural epimers of shikimic acid, thus allowing access to glycomimetics that mimic other CLR ligands. This strategy will therefore allow access to glycomimetic agonists to target any CLR of interest. Finally, I have outlined a methodology to probe antigen presentation in DCs. Using glycopolymers bearing peptide cargo, we are poised to explore two distinct mechanisms of antigen presentation in DCs. We envision this strategy will elucidate the putative roles CLRs may play in antigen presentation. Moreover, this approach may validate CLRs as potential therapeutic targets for vaccine design.

Available in PDF, EPUB and Kindle. Book excerpt: A new focus on glycoscience, a field that explores the structures and functions of sugars, promises great advances in areas as diverse as medicine, energy generation, and materials science, this report finds. Glycans-also known as carbohydrates, saccharides, or simply as sugars-play central roles in many biological processes and have properties useful in an array of applications. However, glycans have received little attention from the research community due to a lack of tools to probe their often complex structures and properties. Transforming Glycoscience: A Roadmap for the Future presents a roadmap for transforming glycoscience from a field dominated by specialists to a widely studied and integrated discipline, which could lead to a more complete understanding of glycans and help solve key challenges in diverse fields.

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 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.
