Fluorinated Carbohydrates as Lectin Ligands: Simultaneous Screening of a Monosaccharide Library and Chemical Mapping by F-19 NMR Spectroscopy
(American Chemical Society, 2020-12-18)
Molecular recognition of carbohydrates is a key step in essential biological processes. Carbohydrate receptors can distinguish monosaccharides even if they only differ in a single aspect of the orientation of the hydroxyl ...
The two domains of human galectin-8 bind sialyl- and fucose-containing oligosaccharides in an independent manner. A 3D view by using NMR
(Royal Society of Chemistry, 2021-06-01)
The interaction of human galectin-8 and its two separate N-terminal and C-terminal carbohydrate recognition domains (CRD) to their natural ligands has been analysed using a synergistic combination of experimental NMR and ...
Novel carboxylate-based glycolipids: TLR4 antagonism, MD-2 binding and self-assembly properties
(Nature Publishing, 2019-01-29)
New monosaccharide-based lipid A analogues were rationally designed through MD-2 docking studies. A panel of compounds with two carboxylate groups as phosphates bioisosteres, was synthesized with the same glucosamine-bis-succinyl ...
Novel Dextran-Supported Biological Probes Decorated with Disaccharide Entities for Investigating the Carbohydrate-Protein Interactions of Gal-3.
(Wiley, 2018-11-30)
The quest for novel natural-like biomolecular probes that can be used to gain information on biological recognition events is of topical interest to several scientific areas. In particular, the recognition of carbohydrates ...
Glycans in drug discovery
(Royal Soc Chemistry, 2019-07-26)
Glycans are key players in many biological processes. They are essential for protein folding and stability and act as recognition elements in cell-cell and cell-matrix interactions. Thus, being at the heart of medically ...
Hypoxia Reduces Cell Attachment of SARS-CoV-2 Spike Protein by Modulating the Expression of ACE2, Neuropilin-1, Syndecan-1 and Cellular Heparan Sulfate
(Taylor & Francis, 2021-06-06)
A main clinical parameter of COVID-19 pathophysiology is hypoxia. Here we show that hypoxia decreases the attachment
of the receptor-binding domain (RBD) and the S1 subunit (S1) of the spike protein of SARS-CoV-2 to ...
Molecular Recognition in C-Type Lectins: The Cases of DC- SIGN, Langerin, MGL, and L-Sectin
(2020-11-02)
Carbohydrates play a pivotal role in intercellular communication processes. In particular, glycan antigens are key for sustaining homeostasis, helping leukocytes to distinguish damaged tissues and invading pathogens from ...
Unraveling Sugar Binding Modes to DC-SIGN by Employing Fluorinated Carbohydrates
(MDPI, 2019-06-25)
A fluorine nuclear magnetic resonance (F-19-NMR)-based method is employed to assess the binding preferences and interaction details of a library of synthetic fluorinated monosaccharides towards dendritic cell-specific ...
Targeting Galectins With Glycomimetics
(Frontiers Media, 2020-08-07)
Among glycan-binding proteins, galectins, beta-galactoside-binding lectins, exhibit relevant biological roles and are implicated in many diseases, such as cancer and inflammation. Their involvement in crucial pathologies ...
Fluorinated carbohydrates as chemical probes formolecular recognition studies. Current statusand perspectives
(Royal Society of Chemistry, 2020-06-21)
This review provides an extensive summary of the effects of carbohydrate fluorination with regard to changes in physical, chemical and biological properties with respect to regular saccharides. The specific structural, ...
