4,6‐O‐Phenylboronic Ester Protection for 1,2‐cis‐α‐Selective Glucosylation

open access: yesAsian Journal of Organic Chemistry, Volume 14, Issue 8, August 2025.
The 4,6‐O‐phenylboronic ester protection for 1,2‐cis‐α‐selective glucosylation, previously reported by the Crich group, was revisited and the stereodirecting effect of the cyclic protecting group was unveiled. 4,6‐O‐Phenylboronic ester‐protected glucosyl and 2‐azido‐2‐deoxyglucosyl donors exhibited higher α‐selectivity of the glucosylation than the ...

Structural Characterization and Physicochemical Property of a Purified Fucosylated Glycosaminoglycan Sulfate From Holothuria leucospilota

open access: yeseFood, Volume 6, Issue 4, August 2025.
(1) The main chain structure of Holothuria leucospilota polysaccharides (HLP‐Ⅰ) was presumed to be roughly as →3)‐β‐d‐GalpNAc‐(1→4)‐β‐d‐GlcpA‐(1→. (2) with T‐Fucp on the branched chain or a rockulose chain consisting of →3,4)‐α‐l‐Fucp‐(1→. (3) HLP‐Ⅰ showed high amorphous platelet content and disordered arrangement, while the molecule adapted a sphere ...

Wine‐Processed Polygonatum cyrtonema Hua Polysaccharides Alleviating Cognitive Dysfunction in CUMS Mice by Regulating Intestinal Microbiota

open access: yesFood Science &Nutrition, Volume 13, Issue 8, August 2025.
A homogeneous polysaccharide JP3 with neuroprotective properties was isolated from wine processed Polygonatum cyrtonema Hua. JP3 significantly enriched the abundance of Lactobacillus murinus in the gut microbiota of CUMS mice. Compared with inulin, JP3 better promotes the proliferation of Lactobacillus murinus and the production of butyric acid and ...
