Fluorogenic Sydnones for Bioorthogonal Labeling of DNA

open access: yesChemistry – 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.

Control of Gemcitabine Activity With Blue and Red Light

open access: yesChemistry – A European Journal, EarlyView.
Treating cancer with chemotherapy is generally associated with many side effects, which can be addressed by selectively releasing the desired drugs with visible light. Sixteen new blue light‐activatable cytostatics were introduced, with the gemcitabine derivative exhibiting ideal properties.

Rapid Access to Photoswitchable RNA Binders: Fluorination Enhances Protein Rescue by Exon Inclusion

open access: yesChemistry – A European Journal, EarlyView.
An adaptable approach, many light‐switchable RNA binders. We report a versatile strategy for rapidly synthesizing photoswitchable RNA binders. The ligands can target SMN2 pre‐mRNA, restoring the levels of the corresponding protein by exon‐inclusion rescue.

Multi‐state Photoswitching in Thienoquinoid‐Based Fluorescent Trithiophenes

open access: yesChemistry – A European Journal, EarlyView.
A methine‐bridged trithiophene with a thienoquinoid core undergoes photoisomerization of both C═C bonds, affording three geometrical isomers in a ratio controlled by the irradiation wavelength. Despite full π‐conjugation, the system retains fluorescence, enabling wavelength‐addressable multi‐state switching with luminescent readout.

The Mechanism of Visible‐Light Photochemical Rearrangements of Conjugated Amide Enolates

open access: yesChemistry – A European Journal, EarlyView.
Visible light irradiation of extended enolates of N‐benzylamides leads to homolytic C─N Bond cleavage, generating a biradical. Computational and mechanistic studies suggest rapid radical recombination within a solvent cage to give either ring‐expanded or rearranged products. ABSTRACT Deprotonation of conjugated amides forms colored solutions of lithium
