2-(Trimethylsilyl)ethyl glycosides. 3. Synthesis, anomeric deblocking, and transformation into 1,2-trans 1-O-acyl sugars

Role of intestinal surfactant-like particles as a potential reservoir of uropathogenic Escherichia coli

“…Proteins were biotinylated using commercially available reagents (Sigma, St. Louis, MO, USA). Limited amounts of the digalactoside GalK-(1-4)Gal, the speci¢c receptor for PapG, were available, synthesized as described previously [30]. The limited amount available permitted use of only a single concentration of this inhibitor (18 mM).…”

Chemical Synthesis of Oligosaccharides: Efficiency and Selectivity.

“…Also to be noted is that the aglycon in 4 0 which is used as a hydrophobic tag can be selectively cleaved (ref. 41) in case one wants to conjugate the formed oligosaccharide with other structures.…”

Design and Synthesis of Gentiohexaosyl Derivatives for an ANP Receptor Antagonist, HS-142–1

“…To a solution of 6 (330 mg, 0.1 mmol) in MeOHI THF (3 ml/3 ml) was added 0.1 N methanoic sodium methoxide (I mI (5). A mixture of 37 (33 mg, 12 jlmol) and 20% Pd(OHh/C (I0mg) in THF/MeOH (I ml/l ml) was stirred under a hydrogen atmosphere at SOC for 48 h, then the catalyst was removed by filtration, and the filtrate was concentrated.…”
