Carbon Dots for Cancer Theranostics: Synthesis Strategies, Luminescence Properties, and Advances in Bioimaging‐Guided Diagnosis and Therapy

Chemistry – A European Journal, EarlyView.
Lighting up the path to precision oncology: This review comprehensively summarizes the rational design of carbon dots (CDs), elucidating how core size, surface chemistry, and heteroatom doping dictate their luminescence mechanisms. Special emphasis is placed on engineering NIR‐II emissive CDs for deep‐tissue imaging.

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.

Catalysis of Oxidative Protein Folding by Small-Molecule Diselenides

, 2016
The production of recombinant, disulfide-containing proteins often requires oxidative folding in vitro. Here, we show that diselenides, such as selenoglutathione, catalyze oxidative protein folding by O2.

Chalcogen Bonding Induced Tetraselenides from Twisted Diselenides

, 2020
The first sterically controlled oxidation of mesoionic selone using copper(II) salt was demonstrated. The present methodology gave access to a rare tetraselenide from dimerized diselenides through chalcogen bonding (ChB). Besides, a similar approach with

Redox‐Active Bisphosphines Based on a W(II)‐Propargyl Complex Backbone

European Journal of Inorganic Chemistry, EarlyView.
Three bisphosphine ligands based on tungsten(II) propargyl‐type alkyne complexes were synthesized and characterized. The methanolate derivative was used as a metalla‐ligand for the preparation of a binuclear bisphosphine‐κ2‐PdCl2 complex. In both cases, IR spectroelectrochemistry (IR‐SEC) measurements revealed a successive process following oxidation ...

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.
