Synthesis, Biological Evaluation, and Molecular Docking of Tellurium‐Containing Benzothiazole Derivatives as Enzyme Inhibitors of DNA Gyrase and Dihydrofolate Reductase

open access: yesBioMed Research International, Volume 2026, Issue 1, 2026.
Tellurium‐containing heterocycles represent an emerging class of organochalcogen compounds with notable redox properties and antimicrobial potential. Incorporation of tellurium into sulfur‐ and nitrogen‐containing frameworks can enhance biological activity through increased polarizability and favorable noncovalent interactions.

Cyanines Substituted on the Polymethine Chain: Synthesis, Resulting Properties, and Application Use Cases

open access: yesChemPlusChem, Volume 90, Issue 12, December 10, 2025.
Cyanines are small‐molecule dyes with a polymethine chain. For various applications, their properties can be tuned by varying not only chain length and auxochrome end groups but also the substituents on the polymethine chain. Here, we review the synthesis, properties, and applications of cyanines with substituents on the polymethine chain.

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

open access: yesEnvironmental and Molecular Mutagenesis, Volume 66, Issue S2, Page 166-180, December 2025.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

New Chiral Ebselen Analogues with Antioxidant and Cytotoxic Potential

open access: yesMolecules, 2017
New chiral camphane-derived benzisoselenazol-3(2H)-ones and corresponding diselenides have been synthetized using a convenient one-pot procedure. Se-N bond was efficiently converted to an Se-Se bond, which could also be easily re-oxidized to the initial ...
