Synthesis of Polycyclic Oxazolinium Compounds from Aryloxazolines and Alkynes via Dual Photoredox/Gold Catalysis and Rhodium Catalysis

Advanced Synthesis &Catalysis, Volume 367, Issue 18, September 29, 2025.
A series of polycyclic oxazolinium compounds is synthesized from various aryloxazolines with silyl‐substituted alkynes and internal alkynes via dual photoredox/gold catalysis and Rh‐catalyzed C–H bond functionalization, and affords silyl‐substituted polycyclic oxazoliniums and polycyclic oxazoliniums, respectively.

Laxative Effect of Lactobacillus paracasei Glory LP16 on Loperamide‐Induced Constipation in Mice

eFood, Volume 6, Issue 4, August 2025.
ABSTRACT Constipation is a common gastrointestinal disease. In recent years, probiotic intervention has often been used to solve such problems. However, the results of existing studies on different intervention times and dose differences are not consistent. Therefore, it is necessary to conduct research on specific strains.

Functional Profiles of Phyllosphere and Rhizosphere Metagenomes Differ Across Milkweed Species

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
We characterised milkweed microbiomes using a metagenomics approach to investigate the functional potential of endophytic phyllosphere and rhizosphere communities. We found evidence that the composition of potential PSM genes varied across milkweeds in spp. specific responses, for both phyllospheres and rhizospheres, and in response to monarch feeding.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Expansion of the diversity of dispersin scaffolds

Acta Crystallographica Section D, Volume 81, Issue 3, Page 130-146, March 2025.
Five GH20‐family dispersins were characterized for activity on aryl glycosides and poly‐β‐1,6‐linked N‐acetyl‐d‐glucosamine oligomers and three crystal structures were solved, including two complexes with bound inhibitors.Microorganisms are known to secrete copious amounts of extracellular polymeric substances (EPS) that form complex matrices around ...

Purification, characterization, and cloning of a Spodoptera frugiperda Sf9 beta-N-acetylhexosaminidase that hydrolyzes terminal N-acetylglucosamine on the N-glycan core

, 2006
Paucimannosidic glycans are often predominant in N-glycans produced by insect cells. However, a beta-N-acetylhexosaminidase responsible for the generation of paucimannosidic glycans in lepidopteran insect cells has not been identified.

Discovery of Lacto‐N‐Biosidases and a Novel N‐Acetyllactosaminidase Activity in the CAZy Family GH20: Functional Diversity and Structural Insights

ChemBioChem, Volume 26, Issue 2, January 14, 2025.
We report several new lacto‐N‐biosidases (LNBases) and the first report of N‐acetyllactosaminidase (LacNAcase) activity in CAZy family GH20, i. e. enzymes that catalyze the release heterodisaccharides from human milk oligosaccharides and related glycans. New crystal structures comparing a specific LNBase to an enzyme with dual LacNAcase/LNBase activity
