Properties of disulfide radical anions and their reactions in chemistry and biology

Redox Biochemistry and Chemistry
Disulfide radical anions (RSSR•−) derive both from the direct electron attachment to disulfide-containing compounds and the reaction of thiyl radicals with thiolate, being also reversible (RS• + RS− ⇆ RSSR•−).

Effects of Panthenol and N-Acetylcysteine on Changes in the Redox State of Brain Mitochondria under Oxidative Stress In Vitro

Antioxidants, 2021
The glutathione system in the mitochondria of the brain plays an important role in maintaining the redox balance and thiol–disulfide homeostasis, whose violations are the important component of the biochemical shifts in neurodegenerative diseases ...

Bioorthogonal Photoactivation of 2‐Nitrobenzyl Caged Doxorubicin Anticancer Prodrugs on Gold Nanostars

Advanced Materials, EarlyView.
Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Gallium‐Doped MXene Nanozymes Protect Liver Through Multi‐Death Pathway Blockade and Hepatocyte Regeneration

Advanced Science, EarlyView.
This study develops gallium‐doped V2C MXene nanozymes (Ga‐V2C) to treat acetaminophen‐induced liver injury through multi‐death pathway blockade and hepatocyte regeneration. Unlike conventional single‐target therapies like N‐acetylcysteine, Ga‐V2C nanozymes enable oxidative stress suppression, apoptosis, and ferroptosis inhibition, and enhanced ...

A GLUTAMATE CYSTEINE LIGASE Gene StGSH1 Regulated by StERF10 Enhanced Glutathione Accumulation and Adaptation to Low Phosphorus Stress in Potato

Advanced Science, EarlyView.
The StERF10‐StGSH1 module coordinates glutathione (GSH) biosynthesis under low‐phosphorus stress. The low‐phosphate‐induced AP2/ERF transcription factor StERF10 directly activates the transcription of StGSH1 and enhances GSH accumulation. Consequently, GSH scavenges reactive oxygen species and provides sulfur for sulfolipid synthesis, facilitating the ...

INVESTIGATING THE IN VIVO EFFECTS OF COPPER COORDINATION COMPOUNDS WITH THIOSEMICARBAZONES ON ERYTHROCYTE REDOX BALANCE

Journal of Experimental and Molecular Biology
Thiol-disulfide homeostasis plays a vital role in cellular and systemic functions, regulating biosynthetic reactions, growth, transport, repair, and redox signaling through the dynamic interplay between thiol (-SH) and disulfide (-S-S-) states.

Bacteriophage‐Mimetic DNA Origami Needle for Targeted Membrane Penetration and Cytosolic Cargo Delivery

Advanced Science, EarlyView.
We designed a synthetic DNA origami needle‐like structure inspired by bacteriophages for targeted drug delivery. Functionalized with trastuzumab antibodies, cholesterol, and dyes, it selectively targets SKBR3 cancer cells. A glutathione‐triggered dye payload enables controlled release, and delivery is verified using confocal microscopy and live cell ...

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

Advanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

PDIA3 Inhibition Facilitates Sensitivity of IKE‐Induced Ferroptosis via STAT3/LCN2 Axis to Improve Glioblastoma Therapy

Advanced Science, EarlyView.
In this manuscript, protein disulfide isomerase A3 (PDIA3) is identified as a key factor mediating the susceptibility of ferroptosis in GBM. Inhibition of PDIA3 enhances IKE or cystine starvation‐induced ferroptosis in GBM cells by resulting in the accumulation of lipid peroxidation and a reduction in GSH level.
