Fully Reversible Regulation of 8‐17 DNAzyme Activity Using Nucleoside‐Based Diarylethenes

open access: yesChemistry – A European Journal, EarlyView.
The site‐specific incorporation of nucleosidic diarylethenes into the 8–17 deoxyribozyme (DNAzyme) identified position 2.1 as optimal. Compound dU‐PhtBu enabled efficient light‐dependent control of catalytic activity, while maintaining thermal stability and reversibility.

Synthesis of Oligonucleotide Conjugates Employing a Diselenide Linker

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT In this study, we report the synthesis of an alkylene linker containing a terminal 2‐cyanoethyl protected selenium functionality for coupling at the 5'‐end of an oligonucleotide by solid phase synthesis for the preparation of oligonucleotide conjugates.

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.

An Electrophilic Uridine Building Block for Post‐Synthetic RNA Modification as Exemplified for Spin Labeling

open access: yesChemistry – A European Journal, EarlyView.
An electrophilic 5‐isothiocyanatomethyl uridine building block enables modular post‐synthetic RNA labeling with primary amine‐containing probes. Positioning the functionality in the major groove minimizes structural perturbation and allows facile conjugation of sensitive tags such as TEMPO spin labels for paramagnetic relaxation enhancement studies ...

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.

Stereochemical Control in the Matteson Reaction

open access: yesChemistry – A European Journal, EarlyView.
The Matteson homologation is a highly versatile method for the stereoselective insertion of carbenoids into boronic esters. Through iterative application of the process, complex chiral molecules can be synthesized. The stereoselectivity of the reaction is determined by a chiral diol incorporated in the boronic ester.

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.
