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 ... -
Fluorine Labeling of Nanoparticles and In Vivo 19F Magnetic Resonance Imaging
(American Chemical Society, 2021-03-24)Fluorinated nanoparticles have increasing applications, but they are still challenging to prepare, especially in the case of water-soluble fluorinated nanoparticles. Herein, a fluorine labeling strategy is presented that ... -
Galectin-4 N-Terminal Domain: Binding Preferences Toward A and B Antigens with Different Peripheral Core Presentations
(Frontiers Media, 2021-04-21)The tandem-repeat Galectin-4 (Gal-4) contains two different domains covalently linked through a short flexible peptide. Both domains have been shown to bind preferentially to A and B histo blood group antigens with different ... -
Gene Prioritization, Communality Analysis, Networking and Metabolic Integrated Pathway to Better Understand Breast Cancer Pathogenesis
(Nature Publishing Group, 2018-11-12)Consensus strategy was proved to be highly efficient in the recognition of gene-disease association. Therefore, the main objective of this study was to apply theoretical approaches to explore genes and communities directly ... -
Glycan structures and their interactions with proteins. A NMR view
(Elsevier, 2019-12)Carbohydrate molecules are essential actors in key biological events, being involved as recognition points for cell-cell and cell-matrix interactions related to health and disease. Despite outstanding advances in cryoEM, ... -
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 ... -
Glycosyl Oxocarbenium Ions: Structure, Conformation, Reactivity, and Interactions
(American Chemical Society, 2021-06-01)Conspectus We also highlight that, from a chemical perspective, the glycosylation reaction can be described as a continuum, from unimolecular SN1 with naked oxocarbenium cations as intermediates to bimolecular SN2-type ... -
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 ... -
