Introduction of a Double‐Headed Nucleotide Into G‐Quadruplex DNA: Position‐Dependent Stabilization and Structural Insights

Chemistry – A European Journal, EarlyView.
A double‐headed bis‐guanine (G) nucleotide (GG) was evaluated as a noncanonical building block in G‐quadruplexes (G4s). Biophysical and computational analyses reveal that GG can directly participate in G‐tetrads and strongly stabilize G4s in a position‐ and topology‐dependent manner. These findings establish design rules for using GG to engineer highly

4′‐ThioRNA Substitution and Sense‐Strand Segmentation for the Design of Functional Fully Modified siRNAs Targeting SARS‐CoV‐2

Chemistry – A European Journal, EarlyView.
4′‐ThioRNA was broadly tolerated across multiple positions in SARS‐CoV‐2‐targeting siRNAs, but full 4'‐thio modification of both strands caused a reduction in RNAi activity. Sense‐strand segmentation improved RNAi and antiviral activity, particularly when the nick was located at position 10 from the 5′‐end of the sense strand, thereby unlocking the ...

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core

Chemistry – A European Journal, EarlyView.
RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

Nano MIPs (Molecularly Imprinted Polymers) Prepared From a “Frustrated” Gold Nanoparticle‐Based Pre‐Imprinting Matrix: Enhancing Binding Affinity and Selectivity

Chemistry – A European Journal, EarlyView.
A comparative study across ligand‐stabilized gold nanoparticles and surfactant micelles reveals that molecular imprinting strongly depends on the nanoplatform used for imprinting. “Frustrated” noncovalent interactions within the monolayer on gold nanoparticle surface can be exploited to improve both the binding affinity and selectivity for ...

DNA Nanotechnology Meets Peptide and Protein Self‐Assembly

Chemistry – A European Journal, EarlyView.
Combining DNA nanotechnology with peptide and protein assembly provides complementary platforms for the rational engineering of functional biomaterials. This Perspective discusses the emerging field of self‐assembling DNA‐peptide and DNA‐protein hybrid systems that combine the structural precision and programmability of DNA nanotechnology with the ...
