AI Article Synopsis

  • A branched Man(5) oligosaccharide was created using a method that involved several controlled glycosylation steps on a mannose-tetraol.
  • The synthesis process utilized n-pentenyl orthoester glycosyl-donors, with NIS/BF(3)·Et(2)O as the promoter, in a dichloromethane (CH(2)Cl(2)) solvent.
  • The n-pentenyl chain in the tetraol acceptor was added to improve the solubility of the starting material and to allow for easier modifications at the oligosaccharide's reducing end.

Article Abstract

A branched Man(5) oligosaccharide has been synthesized by sequential regioselective glycosylations on a mannose-tetraol with n-pentenyl orthoester glycosyl-donors promoted by NIS/BF(3)·Et(2)O, in CH(2)Cl(2). An extended n-pentenyl chain was incorporated into the tetraol acceptor to facilitate (a) the solubility of the starting tetraol in CH(2)Cl(2), and (b) future manipulations at the reducing end of the Man(5) oligosaccharide.

A continuous microfluidic glycosylation strategy that requires no chromatography between steps and significantly expedites glycosylation chemistry is described. This practical approach incorporates the advantages of imidazolium-based chromatography-free purification and in situ mass spectrometry reaction monitoring to achieve fast reaction optimization and shorter reaction times. We demonstrate the utility of this strategy in the synthesis of a series of glycoside targets, including an α-(1,6)-trimannoside and a branched Man oligomannoside, within 1 day.

Aberrant N-linked glycosylation is a prominent feature of cancers. Perturbance of oligosaccharide structure on cell surfaces directly affects key processes in tumor development and progression. In spite of the critical role played by N-linked glycans in tumor biology, the discovery of small molecules that specifically disturbs the N-linked glycans is still under investigation.

The "carbohydrate chemical mimicry" exhibited by sp -iminosugars has been utilized to develop practical syntheses for analogs of the branched high-mannose-type oligosaccharides (HMOs) Man and Man . In these compounds, the terminal nonreducing Man residues have been substituted with 5,6-oxomethylidenemannonojirimycin (OMJ) motifs. The resulting oligomannoside hemimimetic accurately reproduce the structure, configuration, and conformational behavior of the original mannooligosaccharides, as confirmed by NMR and computational techniques.

A wide range of glycoproteins can be recombinantly expressed in aglycosylated forms in bacterial and cell-free production systems. To investigate the effect of glycosylation of these proteins on receptor binding, stability, efficacy as drugs, pharmacodynamics and pharmacokinetics, an efficient glycosylation platform is required. Here, we present a cell-free synthetic platform for the in vitro N-glycosylation of peptides mimicking the endoplasmic reticulum (ER) glycosylation machinery of eukaryotes.
