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.
