Successive Azide and DNA Functionalization for Reversible and Controlled Association of Single‐Wall Carbon Nanotubes

Chemistry – A European Journal, EarlyView.
A newly synthesized bifunctional azide—diazonium linker allows robust one‐step introduction of azido groups to single‐wall carbon nanotubes. Versatility of the azido groups as reactive handles is demonstrated by further derivatization with 6‐carboxyfluorescein and oligonucleotides.

A Selectfluor‐based Polonovski Rearrangement Leading to Novel Entities for Synthetic and Medicinal Applications

Chemistry – A European Journal, EarlyView.
Starting from carboxylic acids and Selectfluor‐derivatives, functionalized diazabicyclooctanes can be obtained via a novel Polonovski‐type rearrangement proceeding under mild reaction conditions. Besides their use in organic synthesis the unique structure and reactivity of the rearrangement products enables applications in medicinal chemistry ...

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

Chemistry – A European Journal, EarlyView.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

Control of Gemcitabine Activity With Blue and Red Light

Chemistry – 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.

Multimodal Fluorescent MOF@BODIPY Platform: Bridging Sensing and Mechanistic Insight

Chemistry – A European Journal, EarlyView.
ABSTRACT Hybrid metal–organic frameworks (MOFs) that integrate organic chromophores constitute powerful platforms for optical sensing by combining structural order with tunable photophysics. Incorporating photoresponsive chromophores into MOFs enables sensitive probing of guest–framework interactions through well‐defined luminescent signatures. Herein,

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

Cytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...
