pharmacology | use of a chemoenzymatic synthetic approach to synthesize six 3-O-sulfated oligosaccharides, including three hexasaccharides and three octasaccharides. The synthesis is achieved by rearranging the enzymatic modification sequence to accommodate the substrate specificity of 3-O-sulfotransferase 3, analysis of the impact of 3-O-sulfation on the conformation of the pyranose ring of 2-O-sulfated iduronic acid using NMR spectroscopy, and on the correlation between ring conformation and anticoagulant activity. An octasaccharide interacts with antithrombin and displays anti factor Xa activity. The octasaccharide displays a faster clearance rate than fondaparinux, an FDA-approved pentasaccharide drug, in a rat model, making this octasaccharide a potential short-acting anticoagulant drug candidate that could reduce bleeding risk. The presence of the -GlcNS3S6S-IdoA2S- disaccharide unit is required for anticoagulant activity | Homo sapiens |

additional information | use of a chemoenzymatic synthetic approach to synthesize six 3-O-sulfated oligosaccharides, including three hexasaccharides and three octasaccharides. The synthesis is achieved by rearranging the enzymatic modification sequence to accommodate the substrate specificity of 3-O-sulfotransferase 3, analysis of the impact of 3-O-sulfation on the conformation of the pyranose ring of 2-O-sulfated iduronic acid using NMR spectroscopy, and on the correlation between ring conformation and anticoagulant activity. An octasaccharide interacts with antithrombin and displays antifactor Xa activity. The two 3-O-sulfotransferase (3-OST) isoforms, 3-OST-1 and 3-OST-3 (EC 2.8.2.30), are employed to install the GlcNS3SĀ±6S residue into different saccharide sequences. The 3-OST-1 enzyme introduces a sulfation to form a GlcNS3S6S residue that is linked to a GlcA residue at the nonreducing end, forming the disaccharide unit of -GlcAGlcNS3S6S-, whereas the 3-OST-3 enzyme introduces a sulfation to form a GlcNS3S residue that is linked to an IdoA2S residue at the nonreducing end, forming the disaccharide unit of -IdoA2S-GlcNS3S-.

metabolism | the sulfation at the 3-OH position of glucosamine is an important modification in forming structural domains for heparan sulfate to enable its biological functions. Seven 3-O-sulfotransferase isoforms in the human genome are involved in the biosynthesis of 3-O-sulfated heparan sulfate | Homo sapiens |
