sp2-Iminosugars targeting human lysosomal β-hexosaminidase as pharmacological chaperone candidates for late-onset Tay-Sachs disease
(Taylor & Francis, 2022)
The late-onset form of Tay-Sachs disease displays when the activity levels of human β-hexosaminidase A (HexA) fall below 10% of normal, due to mutations that destabilise the native folded form of the enzyme and impair its ...

A Bicyclic 1-Deoxygalactonojirimycin Derivative as a Novel Pharmacological Chaperone for GM1 Gangliosidosis
(Cell Press, 2013)
Lysosomal β-galactosidase (β-Gal) deficiency causes a group of disorders that include neuronopathic GM1 gangliosidosis and non-neuronopathic Morquio B disease. We have previously proposed the use of small molecule ligands ...

Bicyclic (galacto)nojirimycin analogues as glycosidase inhibitors: Effect of structural modifications in their pharmacological chaperone potential towards β-glucocerebrosidase
(Royal Society of Chemistry (Great Britain), 2011)
A molecular-diversity-oriented approach for the preparation of bicyclic sp2-iminosugar glycomimetics related to nojirimycin and galactonojirimycin is reported. The synthetic strategy takes advantage of the ability of ...

Understanding multivalent effects in glycosidase inhibition using C-glycoside click clusters as molecular probes
(Royal Society of Chemistry, 2016)
The synthesis of the first examples of multivalent C-glycosides based on C60-fullerene or β-cyclodextrin cores by way of Cu(I)-catalyzed azide–alkyne cycloadditions is reported. These compounds were designed as molecular ...

Probing the Inhibitor versus Chaperone Properties of sp2-Iminosugars towards Human β-Glucocerebrosidase: A Picomolar Chaperone for Gaucher Disease
(MDPI, 2021)
A series of sp2-iminosugar glycomimetics differing in the reducing or nonreducing character, the configurational pattern (d-gluco or l-ido), the architecture of the glycone skeleton, and the nature of the nonglycone ...

Stereoselective Synthesis of Nojirimycin α-C-Glycosides from a Bicyclic Acyliminium Intermediate: A Convenient Entry to N,C-Biantennary Glycomimetics
(American Chemical Society, 2022)
A simple and efficient method for the stereoselective synthesis of nojirimycin α-C-glycoside derivatives has been developed using a bicyclic carbamate-type sp2-iminosugar, whose preparation on a gram scale has been optimized, ...

A versatile stereocontrolled synthesis of 2-deoxyiminosugarC-glycosides and their evaluation as glycosidase inhibitors
(Royal Society of Chemistry, 2021)
A highly enantioselective synthesis of (R,S) or (S,S)-2,6-disubstituted dehydropiperidines has been previously achieved through Sn/Li transmetalation of the corresponding stannylated dehydropiperidines or of their precursors. ...

Probing the Inhibitor versus Chaperone Properties of sp2-Iminosugars towards Human -Glucocerebrosidase: A Picomolar Chaperone for Gaucher Disease
(Molecular Diversity Preservation International, 2018)
A series of sp2-iminosugar glycomimetics differing in the reducing or nonreducing character, the configurational pattern (d-gluco or l-ido), the architecture of the glycone skeleton, and the nature of the nonglycone ...

Spacer-mediated synthesis of bis-spiroketal disaccharides: Nonsymmetrical furanose-pyranose difructose dianhydrides
(2007)
The stereochemical outcome of the dimerization reaction of D-fructose, leading to tricyclic bis-spiroketal systems, can be tuned by inserting a xylylene template between the reacting moieties. Spirocyclization becomes then ...

Chemical and Enzymatic Approaches to Carbohydrate-Derived Spiroketals: Di-D-Fructose Dianhydrides (DFAs)
(MDPI AG, 2008)
Di-D-fructose dianhydrides (DFAs) comprise a unique family of stereoisomeric spiro-tricyclic disaccharides formed upon thermal and/or acidic activation of sucrose- and/or D-fructose-rich materials. The recent discovery of ...
