Comparative transcriptomics reveals key differences in the response to milk oligosaccharides of infant gut-associated bifidobacteria. [PDF]
Breast milk enhances the predominance of Bifidobacterium species in the infant gut, probably due to its large concentration of human milk oligosaccharides (HMO). Here we screened infant-gut isolates of Bifidobacterium longum subsp.

The synthesis of betulinic acid and echinocystic acid saponins featuring QS‐21 minimal immunogenic motif is reported. These chimeric saponins, together with previously synthesized Lewis‐X‐containing triterpenoid saponins and a rhamnose‐modified saponin, were assessed for their toxicological and immunological profiles in wild‐type and/or hDC‐SIGN ...

Synthesis of C-glycosyl phosphonate derivatives of 4-amino-4-deoxy-α-ʟ-arabinose
The incorporation of basic substituents into the structurally conserved domains of cell wall lipopolysaccharides has been identified as a major mechanism contributing to antimicrobial resistance of Gram-negative pathogenic bacteria.

Identification and structural characterisation of a partially arabinosylated lipoarabinomannan variant isolated from a Corynebacterium glutamicum ubiAmutant [PDF]
Arabinan polysaccharide side-chains are present in both Mycobacterium tuberculosis and Corynebacterium glutamicum in the heteropolysaccharide arabinogalactan (AG), and in M. tuberculosis in the lipoglycan, lipoarabinomannan (LAM).

α-Selective glycosylation affords mucin-related GalNAc amino acids and diketopiperazines active on Trypanosoma cruzi [PDF]
This work addresses the synthesis and biological evaluation of glycosyl diketopiperazines (DKPs) cyclo[Asp-(αGalNAc)Ser] 3 and cyclo[Asp-(αGalNAc)Thr] 4 for the development of novel anti-trypanosomal agents and Trypanosoma cruzi trans-sialidase (TcTS ...

New Inhibitors of β‐1,4‐Galactosyltransferase I Discovered by Virtual Screening
β‐1,4‐Galactosyltransferase I (β‐1,4‐GALT1) is essential in the galactosylation of glycoproteins and is a promising drug target. In this study, an in silico screening of virtual compound libraries was peformed to identify novel β‐1,4‐GALT1 inhibitors. Selected hits were evaluated in vitro with the UDP‐Glo kit; IC50 values were determined for the best ...

Osmotic properties of polyethyleneglycols: quantitative features of brush and bulk scaling laws [PDF]
From glycosylated cell surfaces to sterically stabilized liposomes, polymers attached to membranes attract biological and therapeutic interest. Can the scaling laws of polymer "brushes" describe the physical properties of these coats? We delineate conditions where the Alexander - de Gennes theory of polymer brushes successfully describes the ...

Conserved sequence motifs in levansucrases and bifunctional β-xylosidases and α-l-arabinases [PDF]
Comparison of the amino acid sequences of two families of glycosyl hydrolases reveals that they are related in a region in the central part of the sequences.

Structural Insights Into Galectin‐3 Recognition of a Selenoglycomimetic
Galectin‐3, a β‐galactoside‐binding protein, plays a pivotal role in fibrosis and carcinogenesis. We explore the molecular recognition of a seleno‐digalactoside, modified with a benzyl group (SeDG‐Bn), as a potent Gal‐3 inhibitor. Using nuclear magnetic resonance and molecular dynamics simulations, we present a 3D model of the SeDG‐Bn/Gal‐3 complex ...
