Diselenide‐Catalyzed Asymmetric Allenylation of Alkynes

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 11, 16 March 2026.
An asymmetric allenylation of alkynes is described using chiral lactamides‐based diselenides under oxidative conditions. This led to the corresponding allenylamides with enantiomeric excesses up to 72%, and uncovers an interesting stereodivergency feature related to the β‐H‐syn‐elimination of transient Se(IV) intermediates.

Enantioselective Growth of Chiral Serine‐Induced β‐Ag2Se Crystals from an Organoselenium Compound

open access: yesAdvanced Functional Materials, Volume 36, Issue 22, 16 March 2026.
Chiral amino acids direct the enantioselective crystallization of β‐Ag2Se nanocrystals from an organoselenium precursor. L‐ and D‐serine induce distinct morphologies and opposite homochiral adsorption preferences, transferring molecular handedness into the inorganic lattice.

Next‐Generation Antioxidant Strategies: From Nanoformulations to Gene‐Targeted Therapies

open access: yescScience, Volume 2, Issue 1, March 2026.
ABSTRACT Antioxidants play a pivotal role in neutralizing oxidative stress, a key factor in aging and chronic diseases such as cancer, cardiovascular disorders, and neurodegeneration. Although traditional antioxidants such as vitamins C and E, polyphenols, and endogenous enzymes have shown efficacy in laboratory and clinical studies, their therapeutic ...

Synthesis of Unsymmetric Bis(heteroaryl) Selenides by Rhodium‐Catalyzed Exchange Reaction of Heteroaryl Fluorides and Ethers Using Se‐Heteroaryl Carboselenoates

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 5, 7 February 2026.
Various unsymmetric bis(heteroaryl) selenides are synthesized by the rhodium‐catalyzed exchange reaction of heteroaryl fluorides and ethers with Se‐heteroaryl 1‐adamatanecarboselenoates. The synthetic method is applicable to a broad range of five‐ and six‐membered heteroaryl derivatives and provides compounds containing multiple heteroatoms.

The Effect of Organoselenium Compounds on Histone Deacetylase Inhibition and Their Potential for Cancer Therapy

open access: yes, 2021
Genetic and epigenetic changes alter gene expression, contributing to cancer. Epigenetic changes in cancer arise from alterations in DNA and histone modifications that lead to tumour suppressor gene silencing and the activation of oncogenes.
