Interfacing B‐DNA and DNA Mimic Foldamers

Angewandte Chemie International Edition, Volume 64, Issue 31, July 28, 2025.
Helical aromatic oligoamide DNA mimic foldamers that reproduce the shape and charge distribution of duplex B‐DNA have been interfaced with DNA duplexes by means of a new linker that serves both as a DNA hairpin and as an aromatic oligoamide unit. In the resulting chimeric molecules, the linker does not perturb the DNA duplex structure and converts the ...

Enantioselective Anion‐Binding‐Catalyzed Nucleophilic Addition to 4‐Quinolones

European Journal of Organic Chemistry, Volume 28, Issue 27, July 25, 2025.
The first organocatalytic enantioselective formal 1,4‐addition to 4‐quinolones has been developed. This method relies on chiral triazole‐based anion‐binding catalysis using enol nucleophiles, complementing previous metal catalytic approaches. Moderate to good yields and enantioselectivities were achieved by in situ silylation and formation of a key ...

Investigation of the Coordination Chemistry, Biomolecular Interactions, and Cytotoxicity of Heterocyclic Carboxamide Manganese(II) Complexes

European Journal of Inorganic Chemistry, Volume 28, Issue 19, July 12, 2025.
Mononuclear and dinuclear heterocylic carboxamide manganese(II) complexes show strong interactions with calf thymus DNA and bovine serum albumin biomolecules but low cytotoxicity against Caco‐2 and MCF‐7 cancer cell lines and relatively less selective toward the normal KMST‐6 cell line.
