Glycosylation of Conotoxins

open access: yesMarine Drugs, 2013
Conotoxins are small peptides present in the venom of cone snails. The snail uses this venom to paralyze and capture prey. The constituent conopeptides display a high level of chemical diversity and are of particular interest for scientists as tools employed in neurological studies and for drug development, because they target with exquisite ...

Penfluridol Triggers GSDME‐Mediated Immunogenic Pyroptosis to Potentiate Antitumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
A high‐throughput screen of FDA‐approved antipsychotics identifies penfluridol as a potent pyroptosis inducer acting via direct TTI1 inhibition. This triggers TNFA‐NFKB signaling and caspase‐8/‐3‐dependent GSDME cleavage. The compound stimulates antitumor immunity alone and synergizes with anti‐PD‐1 therapy, while low TTI1 expression emerges as a ...

Metabolic Labeling and Visualization of Isoprenoids Using Alkyne‐Modified DMAPP Analogs in Bacillus subtilis

open access: yesAngewandte Chemie, EarlyView.
Fluorescence‐based visualization and targeted mass–spectrometric enrichment of membrane‐embedded isoprenoids in Bacillus subtilis via cell‐permeant, alkynylated DMAPP analogs. ABSTRACT Isoprenoids are a chemically and functionally diverse class of metabolites that underlie essential bacterial physiology including respiration and cell envelope ...

Glycosylation as a dynamic regulator of RLR and cGAS-STING innate immune signalling pathways

open access: yesCommunications Biology
Innate immune sensing by RIG-I-like receptors (RLRs) and the cGAS-STING pathway is tightly regulated by glycosylation. This review summarizes how distinct glycosylation modalities shape antiviral signaling at multiple levels.

Multi‐tissue Metabolic GWAS and Drought‐Responsive Multi‐omics Reveal the Genetic Basis of the Quinoa Metabolome

open access: yesAdvanced Science, EarlyView.
A multi‐omics framework combining multitissue genome‐wide association studies, metabolomics, transcriptomics, proteomics, and functional validation uncovers the genetic basis of specialized metabolism in quinoa. The study identifies hundreds of metabolite‐associated loci, prioritizes candidate genes for saponin, betalain, and flavonoid biosynthesis ...

Chemoenzymatic Synthesis of Heparan Sulfate Oligosaccharides by a Covalent Catch‐and‐Release Approach

open access: yesAngewandte Chemie, EarlyView.
A glycan having a hydrazide tag enables chemoenzymatic synthesis of HS oligosaccharides. The hydrazide can, under mild acidic conditions, react with an aldehyde‐containing resin to give an immobilized hydrazone that is stable under neutral conditions, allowing washing. The product can be released by transiminolysis using aqueous hydroxylamine to give a

Computational analysis reveals non-consensus N-glycosylation sequons in antibody Fab region

open access: yesmAbs
Protein glycosylation at asparagine typically occurs at a consensus motif. However, recent studies have reported instances of N-glycosylation at non-consensus sites, though the mechanisms and implications of these atypical modifications remain unclear ...

Targeting GALNT7 Disrupts the TAZ O‐GalNAcylation Feedback Loop to Suppress Gallbladder Cancer Progression

open access: yesAdvanced Science, EarlyView.
Aberrant GALNT7‐mediated O‐GalNAcylation stabilizes TAZ to drive gallbladder cancer progression through a feed‐forward transcriptional loop. Structure‐based screening identifies Olaparib as a potent GALNT7 antagonist that disrupts this oncogenic axis, providing an immediate therapeutic strategy for this aggressive malignancy.

Carbohydrate Physicochemical Properties: The Innate Hydrogen Bond Donating Capacities of α‐Glucoside and α‐Galactoside Alcohol Groups

open access: yesAngewandte Chemie, EarlyView.
Experimental determination of the innate hydrogen bond donating capacities of the glucose and galactose non‐anomeric alcohols revealed significant variations depending on position and relative configuration, which were quantified on the pKAHY scale, relevant for MedChem purposes, hence providing another tool toward rational glycomimetic development ...
