Stereoselective Synthesis of 1,2‐cis‐α‐Glycosyl Thiols and Trehalose‐Type α,α’‐Thiodisaccharides by Cryo Thiol‐Ene Photocoupling – Thio‐Click Reaction in Frozen State

Chemistry – A European Journal, Volume 31, Issue 20, April 4, 2025.
A double photochemical cryo thiol‐ene coupling process was developed as a general method for the synthesis of 1,2‐cis‐α,α’‐thio‐linked di‐ and oligosaccharides. The procedure includes i) UV‐initiated coupling reaction of 2‐substituted glycals with HSAc in AcOH at −80 °C in frozen state, ii) selective S‐deacetylation of the resulting glycosyl‐α‐SAc ...

Total Synthesis of Kanamycins

Chemistry – A European Journal, EarlyView.
This paper reports on creating a novel synthetic route of kanamycins A and B using the desymmetric boron‐mediated aglycon delivery (BMAD) reaction of meso‐diol acceptor with 1,2‐anhydro donor and regio‐ and stereoselective glycosylation of diol acceptor with trichloroacetimidate donor for introduction of a set of challenging 1,2‐cis‐glycosidic linkages

New technique for enzymic hydrolysis of glycosphingolipids

Journal of Lipid Research, 1969
A method is described for the study of glycosyl ceramide glycosyl hydrolases. Problems arising from the limited solubility of glycosyl ceramides in aqueous media were overcome by coating the substrate on a filter paper disc that had been treated with ...

Bayesian Profiling Multiple Imputation for Missing Electronic Health Records [PDF]

arXiv, 2019
Electronic health records (EHRs) are increasingly used for clinical and comparative effectiveness research, but suffer from missing data. Motivated by health services research on diabetes care, we seek to increase the quality of EHRs by focusing on missing values of longitudinal glycosylated hemoglobin (A1c), a key risk factor for diabetes ...

The Cell Wall Teichuronic Acid Synthetase (TUAS) Is an Enzyme Complex Located in the Cytoplasmic Membrane of Micrococcus luteus [PDF]

, 2010
The cell wall teichuronic acid (TUA) of Micrococcus luteus is a long-chain polysaccharide composed of disaccharide repeating units [-4-β-D-ManNAcAp-(1→6)α-D-Glcp−1-]n, which is covalently anchored to the peptidoglycan on the inner cell wall and extended ...

Lewis‐X‐Containing Triterpenoid Saponins Inhibit DC‐SIGN‐ and L‐SIGN‐Mediated Transfer of HIV‐1 Infection

Chemistry – A European Journal, EarlyView.
The convergent synthesis of Lewis‐X‐containing betulinic acid and echinocystic acid saponins (1 and 2) is presented. The synthetic saponins were shown to inhibit, at the low micromolar range, the DC‐SIGN‐ and L‐SIGN‐mediated transfer of HIV‐1 infection to CD4‐positive cells, whereas free Lewis‐X, aglycones, and structurally similar triterpenoid ...

The human collagen beta(1-O)galactosyltransferase, GLT25D1, is a soluble endoplasmic reticulum localized protein

BMC Cell Biology, 2010
Background Glycosyl transferases transfer glycosyl groups onto their substrate. Localization partially defines their function. Glycosyl transferase 25 domain 1 (GLT25D1) was recently shown to have galactosyltransferase activity towards collagens and ...

Synthesis of the tetrasaccharide repeating unit of the O-specific polysaccharide of Azospirillum doebereinerae type strain GSF71T using linear and one-pot iterative glycosylations

Beilstein Journal of Organic Chemistry, 2020
A straightforward synthetic strategy was developed for the synthesis of the tetrasaccharide repeating unit corresponding to the O-specific polysaccharide of Azospirillum doebereinerae type strain GSF71T in a very good yield adopting sequential ...
