Comparative genomic analysis of azasugar biosynthesis

open access: yesAMB Express, 2021
Azasugars are monosaccharide analogs in which the ring oxygen is replaced with a nitrogen atom. These well-known glycosidase inhibitors are of interest as therapeutics, yet several aspects of azasugars remain unknown including their distribution ...

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

In vitro and in vivo protective efficacies of antibodies that neutralize the RNA N-glycosidase activity of Shiga toxin 2

open access: yesBMC Immunology, 2010
Backgound Shiga toxin 2 (Stx2), one of two Stx liberated by Stx-producing Escherichia coli, is composed of an A subunit monomer and a B subunit pentamer, and is directly linked with hemolytic uremic syndrome in children. The pentameric B subunit binds to

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Hybrid sugars as glycosidase inhibitors en route to 2-deoxy-2-amino C-glycosyl amino acids

open access: yes, 2006
Sugar-azasugar hybrid molecules made up of D-galactose with nojirimycin-δ-lactam and pyrrolidine analogues are synthesized using intramolecular cyclization as a key step from 2-nitro galactal and found to be glycosidase inhibitors.

Brain calcification‐associated JAM2 pathogenic mutations impair JAM2–JAM3 tight junction structure and the blood–brain barrier integrity

open access: yesBrain Pathology, EarlyView.
Pathogenic JAM2 mutations disrupt the JAM2–JAM3 heterodimer structure and tight junction integrity, leading to blood–brain barrier breakdown. Consequently, Jam2‐deficient mice develop prominent midbrain calcification and significant motor impairments, identifying the JAM2–JAM3 interaction as a vital target for primary brain calcification therapeutics ...

The Attempted Synthesis of Indolizidine and Pyrrolizidine Natural Products [PDF]

open access: yes
Aza-sugars are naturally occurring polyhydroxylated alkaloids in which the ring oxygen is replaced by nitrogen. They are reported to have a wide range of biological properties, most importantly as glycosidase inhibitors; these glycosidases play a key ...

Surface charge alterations in urinary extracellular vesicles mirror diabetic kidney disease pathophysiology

open access: yesThe FEBS Journal, EarlyView.
This study reveals that changes in the electrical charge, that is zeta potential of large extracellular vesicles (uEVs) found in urine, can reflect disease progression from diabetes to kidney scarring (fibrosis). With further clinical development, measurement of uEVs charge could provide a simple, noninvasive way to monitor disease progression and help

Development of iminosugar-based glycosidase inhibitors as drug candidates for SARS-CoV-2 virus via molecular modelling and in vitro studies

open access: yes, 2023
We developed new iminosugar-based glycosidase inhibitors against SARS-CoV-2. Known drugs (miglustat, migalastat, miglitol, and swainsonine) were chosen as lead compounds to develop three classes of glycosidase inhibitors (α-glucosidase, α-galactosidase ...

Unraveling A4GALT Mechanism and Its Modulation With Adamantyl‐Galactosylceramide Analogues: Advancing Fabry Disease Therapeutic Strategies

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
A 310‐helix‐mediated conformational switch promotes a front‐face SNi‐like catalysis by human A4GALT. Mechanism‐guided design identifies AdaGalCer as a selective modulator of globotriaosylceramide (Gb3) biosynthesis, opening a clear route toward new Fabry disease therapeutics.
