Dynamic Control of Nucleic Acids Self‐Assembly and Expression Using Photoswitches

Chemistry – A European Journal, EarlyView.
We review here the recent progress made in the design of molecular photoswitches, and highlight their implementation for the dynamic control over nucleic acids self‐assembly and expression. ABSTRACT Synthetic nucleic acids have become readily available and now constitute versatile building blocks in materials science—where they can be used to engineer ...

Synthesis and Reactivity of 3‐Aminosydnones in Cycloaddition Reactions With Alkynes

Chemistry – A European Journal, EarlyView.
The synthesis, functionalization, and reactivity as dipoles of 3‐aminosydnones have been investigated. These neglected compounds undergo smooth cycloaddition reactions with strained alkynes, leading to 1‐aminopyrazoles. ABSTRACT We present in this article the synthesis, functionalization, and properties of 3‐aminosydnones, a forgotten class of ...

Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, EarlyView.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.

Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

Chemistry – A European Journal, EarlyView.
Conjugates of sydnones with cyanine‐styryl dyes combine bioorthogonal reactivity with fluorogenicity. The reactivity with bicyclo[6.1.0]non‐4‐yne (BCN)‐modified DNA showed second‐order rate constants of up to k2 = 2,300 M−1s−1 and fluorescence turn‐on by one magnitude of order.
