Dual drug-loaded halloysite hybrid-based glycocluster for sustained release of hydrophobic molecules
(Royal Society of Chemistry, 2016)
A dual drug-loaded HNT–CD glycocluster delivery system based on halloysite nanotubes and carbohydrate functionalized cyclodextrin was developed by a green protocol using solvent-free microwave irradiation. The nanohybrid ...

Selenium and Sulphur Derivatives of Hydroxytyrosol: Inhibition of Lipid Peroxidation in Liver Microsomes of Vitamin E-deficient Rats
(Springer Nature, 2019)
Purpose: The objective of this study was to evaluate the capacity of modified phenols synthesized from hydroxytyrosol, a natural olive oil phenol, specifically those containing a selenium or sulphur group, to inhibit lipid ...

Bifunctional Squaramide Organocatalysts for the Asymmetric Addition of Formaldehyde tert-Butylhydrazone to Simple Aldehydes
(Wiley-Blackwell, 2018)
The nucleophilic addition of formaldehyde tert-butylhydrazone to simple aldehydes (a formal hetero-carbonyl–ene reaction) can be performed with good reactivity and excellent enantioselectivity by virtue of the dual ...

Pyridine–hydrazone ligands in enantioselective palladium-catalyzed Suzuki–Miyaura cross-couplings
(Elsevier, 2016)
The geometries and coordination properties of modular pyridineehydrazone N,N-ligands containing C2- symmetric trans-2,5-diphenylpyrrolidine and trans-2,5-diphenylpiperidine as the terminal dialkylamino units have been ...

Mechanistic Insight into the Binding of Multivalent Pyrrolidines to α-Mannosidases
(Wiley-Blackwell, 2017)
Novel pyrrolidine-based multivalent iminosugars, synthesized by a CuAAC approach, have shown remarkable multivalent effects towards jack bean α-mannosidase and a Golgi α-mannosidase from Drosophila melanogaster, as well ...

N-Heterotricyclic Cationic Carbene Ligands. Synthesis, Reactivity and Coordination Chemistry
(Royal Society of Chemistry, 2018)
The direct dialkylation of triazolo[4,3-b]isoquinolin-3-ylidene structures readily affords dicationic N-heterotricyclic azolium salts. These are suitable starting materials for the synthesis of transition metal complexes ...

Glycomimetic-based pharmacological chaperones for lysosomal storage disorders: lessons from Gaucher, GM1-gangliosidosis and Fabry diseases
(Royal Society of Chemistry, 2016)
Lysosomal storage disorders (LSDs) are often caused by mutations that destabilize native folding and impair the trafficking of enzymes, leading to premature endoplasmic reticulum (ER)-associated degradation, deficiencies ...

Role of surface tryptophan for peroxidase oxidation of nonphenolic lignin
(BMC (part of Springer Nature), 2016)
Background: Despite claims as key enzymes in enzymatic delignification, very scarce information on the reaction rates between the ligninolytic versatile peroxidase (VP) and lignin peroxidase (LiP) and the lignin polymer ...

Asymmetric Organocatalytic Synthesis of Fluorinated β-Hydroxy Diazenes
(Wiley-Blackwell, 2019)
The nucleophilic addition of formaldehyde tert-butyl hydrazone to fluoromethyl ketones provides a valuable tool for the synthesis of highly functionalized β-hydroxy β-tri- and difluoromethyl diazenes. Excellent reactivities ...

Structural Basis of the Inhibition of GH1 β-glucosidases by Multivalent Pyrrolidine Iminosugars
(Elsevier, 2019)
The synthesis of multivalent pyrrolidine iminosugars via CuAAC click reaction between different pyrrolidine-azide derivatives and tri- or hexavalent alkynyl scaffolds is reported. The new multimeric compounds, together ...
