Oxidative-stress induced protein glutathione mixed-disulfide formation in the ocular lens

, 1996
The biochemistry of protein-glutathione mixed disulfide formation in the ocular lens was examined by 13C-NMR spectroscopic measurements of glutathione oxidative metabolism in intact rabbit lenses maintained in organ culture.

Enhanced strategies for cuproptosis‐like death in bacterial infection treatment

BMEMat, EarlyView.
This review summarizes and examines the molecular mechanisms underlying cuproptosis‐like death. Furthermore, multi‐strategy efficacy enhancement and potential enhancement approaches are analyzed. Abstract Copper, a classical antibacterial metal, has long been of interest and widely used in medical and public health applications.

Glutathione-Priming Nanoreactors Enable Fluorophore Core/Shell Transition for Precision Cancer Imaging

, 2019
In an attempt to develop an imaging probe with ultra-high sensitivity for a broad range of tumors in vivo and inspired by the concept of chemical synthetic nanoreactors, we designed a type of glutathione-priming fluorescent nanoreactor (GPN) with an ...

De Novo Design of Multivalent α/β‐Peptides Mimicking Transcription Factors Targeting the CBP KIX Domain

Chemistry – A European Journal, EarlyView.
A modular, de novo α/β‐peptide design strategy allows fine‐tuning of ligand properties, resulting in multivalent ligands that simultaneously target separate binding sites on the protein surface. ABSTRACT Protein‐protein interactions that regulate gene expression in the nucleus are increasingly recognized as potential therapeutic targets but present ...

Synthesis of Oligonucleotide Conjugates Employing a Diselenide Linker

Chemistry – A European Journal, EarlyView.
ABSTRACT In this study, we report the synthesis of an alkylene linker containing a terminal 2‐cyanoethyl protected selenium functionality for coupling at the 5'‐end of an oligonucleotide by solid phase synthesis for the preparation of oligonucleotide conjugates.

Role of selenium in the pathophysiology of cardiorenal anaemia syndrome

ESC Heart Failure, Volume 12, Issue 2, Page 770-780, April 2025.
Abstract Chronic kidney disease (CKD) and cardiovascular disease (CVD) have multiple bidirectional mechanisms, and anaemia is one of the critical factors that are associated with the progression of the two disorders [referred to as cardiorenal anaemia syndrome (CRAS)].

Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Synthesis of Alpha-Methylselenocysteine, Its Relevant Analogues, and an Unnatural Glutathione Disulfide Core

, 2020
Selenoproteins, such as glutathione peroxidase, have gained interest for their ability to act as antioxidants, and their potential to act as anti-cancer agents. Synthesizing and studying selenoproteins can be problematic, however, due to their propensity

Catalytic Antioxidant Activity of Acyclic and Macrocyclic Selenides: Insights Into Structure–Activity Relationships and Mechanisms From Kinetic and Computational Studies

European Journal of Organic Chemistry, EarlyView.
Structure–activity relationships of antioxidant activities of selenides were established by experimental and computational methods. Several structures displayed strong catalytic activity in an NMR‐based assay. Diverse selenides were shown to act as potent catalytic antioxidants.
