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

Chemistry – 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 ...

RhodaMal Dyes: Novel Red Emissive Fluorophores as Probes for High Contrast Live‐Cell Imaging

Chemistry – A European Journal, EarlyView.
Incorporation of malononitrile into the traditional rhodol framework furnishes RhodaMal (Rhoda = Rhodamine, Mal = Malononitrile;) dyes, a new class of red emissive push–pull chromophores. Conjugating them to triphenylphosphonium cation enables live cell super‐resolution STED microscopy with a 775 nm depletion laser.

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,

Infrared Laser Heating Reveals a Reversible Phase Transition of Phosphofructokinase 1 in Mammalian Cells

Chemistry – A European Journal, EarlyView.
In this study, we present a novel method to investigate the phase behavior of biomolecular condensates in living cells. The method complements FRAP experiments, expanding the existing toolbox for characterization of condensates within living cells. ABSTRACT Metabolic enzymes can operate in concerted networks, so‐called metabolons.

IS RHODAMINE 123 A PHOTOSENSITIZER?

Photochemistry and Photobiology, 1990
Abstract—–Because of conflicting reports on the phototoxicity of rhodamine 123 (Rh 123), we have undertaken a study of Rh 123 photosensitization in severalin vitrosystems. First, Rh 123 is not a photodynamic agent and does not react with singlet oxygen.

Sulfone-Rhodamines: A New Class of Near-Infrared Fluorescent Dyes for Bioimaging

ACS Applied Materials & Interfaces, 2016
Given the wavelength dependence of tissue transparency and the requirement for sufficiently low background autofluorescence, the development of fluorescent dyes with excitation and emission maxima beyond 700 nm is highly desired, but it is a challenging ...

Comparison of rhodamine 6G, rhodamine B and rhodamine 101 spirolactam based fluorescent probes: A case of pH detection

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2022
Ring-opening reaction of rhodamine spirolactam has been widely applied to construct fluorescent probes. The fluorescence properties of the probe were finely tuned for specific purpose through changing the rhodamine fluorophore. However, the influence on response range and kinetic parameters of the probe during the change has been seldom discussed ...
