Glycans and Chirality: Stereoselectivity at the Core of DC‐SIGN's Recognition. A Novel View of the Optimum Minimal Ligand Epitope

Chemistry – A European Journal, EarlyView.
The stereochemical diversity of the “glycan code” enables similar chiral motifs to arise from both D‐ and L‐sugars. Focused on DC‐SIGN–glycan recognition, two diverse monosaccharide scaffolds, D‐Man (D‐Rha) and L‐Gal (L‐Fuc), maintain the exquisite stereochemistry encoded in the minimal binding epitope.

Improved C5‐Amide Bioisosteres for Human Neuraminidase 1 Inhibitors Based on 2‐Deoxy‐2,3‐Didehydro‐N‐Acetyl Neuraminic Acid

ChemMedChem, EarlyView.
This article describes the development of improved NEU1 inhibitors based on the 2‐deoxy‐2,3‐didehydro‐N‐acetyl neuraminic acid scaffold. A series of candidate inhibitors are designed containing bioisosteres of the C5‐amide group and evaluated for activity against NEU1‐4 enzymes.

Sustainable Hydrogen Production by Glycerol and Monosaccharides Catalytic Acceptorless Dehydrogenation (AD) in Homogeneous Phase

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Sustainable hydrogen production can be obtained from hydogen‐rich biomass‐derived organic molecules through Acceptorless Dehydrogenation (AD) reactions. Glycerol and sugars are available in large quantities from industry and can be successfully used as substrates in AD protocols, in the presence of tailored, selective, easily tunable and thermally ...

Spontaneous and Laccase‐Assisted Adsorption of Hemicelluloses Rendering Colloidal Stability of Lignin Nanoparticles at Low pH

ChemSusChem, EarlyView.
Here, a green synthetic approach through spontaneous adsorption and laccase‐induced reactions is introduced to functionalize lignin nanoparticles (LNPs) with hemicelluloses. The resulting lignin–hemicellulose hybrid nanoparticles presented increase colloidal stability at acidic pH compared to the plain LNPs, encouraging their usage in different areas ...

New Glycoconjugates Containing Selenium and Polyphenols. Stereoselective Synthesis by Pummerer‐like Rearrangement.

European Journal of Organic Chemistry, EarlyView.
Two series of novel six‐membered Se‐glycoconjugates containing hydroxycinnamic acids marked by well‐known antioxidant properties are synthesized, exploiting a Mitsunobu reaction and a Pummerer‐like rearrangement. A first example of six‐membered selenosugar with selenium in the ring and bearing an acetal‐like functional group at C‐1 was reported, which ...
