Synthesis of new sulfated disaccharides for the modulation of TLR4-dependent inflammation

Natural sulfated glycans are key players in inflammation through TLR4 activation; therefore synthetic exogenous sulfated saccharides can be used to downregulate inflammation processes. We have designed and synthesized new sulfated compounds based on small and biocompatible carbohydrates that are able to cross the BBB. A suitable protected donor and acceptor, obtained from a unique precursor, have been stereoselectively glycosylated to give an orthogonally protected cellobiose disaccharide. Selective deprotection and sulfation allowed the syntheses of four differentially sulfated disaccharides, which have been characterized by NMR, HRMS and MS/MS. Together with their partially protected precursors, the new compounds were tested on HEK-TLR4 cells. Our results show the potential of small oligosaccharides to modulate TLR4 activity, confirming the need for sulfation and the key role of the 6-sulfate groups to trigger TLR4 signalization.

Hydroxymethyl rotamer populations in disaccharides

Sixteen methyl glucopyranosyl glucopyranoside disaccharides (methyl β-D-Glcp(p-Br-Bz)-(1→x)-β/ α-D-Glcp) containing β-glycosidic linkages (1→2, 1→3, 1→4, and 1→6) were synthesized and analyzed by means of CD and NMR spectroscopy in three different solvent

A method for the selective reduction of carbohydrate 4,6-O-benzylidene acetals

Glucose-derived 4,6-O-benzylidene acetals can be selectively reduced to the corresponding 6-O-benzyl derivatives by the treatment with trifluoroacetic acid and triethylsilane.
