Poly(2‐Oxazoline)‐Based Polyphotoacids: Synthesis, Solution Behavior, and Cellular Uptake of Multi‐Responsive Intracellular Transporters

Macromolecular Rapid Communications, EarlyView.
The ability of photoacids to increase their acidity in response to light irradiation (excited state proton transfer, ESPT) makes them attractive building blocks for the design of stimuli‐responsive copolymers. In this contribution, we present highly biocompatible polyphotoacids based on poly(2‐oxazoline)s bearing 1‐hydroxypyrene units. Low cytotoxicity,

The interaction between mercury(II) and sulfathiazole

Química Nova, 2003
The interaction of mercury(II) with sulfathiazole has been analyzed. IR and NMR spectral studies suggest a coordination of Hg(II) with the Nthiazolic atom, unlike related Hg-sulfadrugs compounds.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Quantitative Competition Binding of Fluorinated Ligands by Real‐Time 19F In‐Cell NMR to Assess Isoform Selectivity in Human Cells

Magnetic Resonance in Chemistry, EarlyView.
Real‐time in‐cell 19F NMR spectroscopy in a flow NMR bioreactor was used to monitor the binding of fluorinated compounds to three cytosolic carbonic anhydrase isoforms in living human cells. The simultaneous observation of the two ligands allowed for the quantitative ranking of their intracellular affinities by competition binding. This approach allows

Multiple‐Use Microplate Assay for Submicromolar Ultra High‐Throughput Separation of Amines Based on their Degree of Substitution

ChemistryOpen, EarlyView.
A reusable microplate platform for ultra‐high‐throughput, submicromolar separation of protonated amines – including alkyl‐, aryl‐, and aralkyl‐types – using a tris(pyridino)‐crown ether selector was introduced; the method enables rapid, zero‐energy, parallel purification fully compatible with automated synthesis workflows.

A Feasibility Study of the Repurposing of Prazosin to Improve Treatment Outcomes in Men Receiving Radiotherapy for Prostate Cancer (MiniRaP‐00)

The Prostate, EarlyView.
ABSTRACT Background Further work is needed to improve treatment outcomes for prostate cancer (PCa), with the repurposing of the α1‐adrenoreceptor antagonists presenting a potential solution. This feasibility clinical trial presents the first prospective data of the use of an α1‐adrenoreceptor antagonist in men undergoing radiotherapy for PCa.

In Situ Self‐Nanostructuring Enables Fast‐Recharging of an Aqueous‐Processed Organic Small Molecule Cathode

Small, EarlyView.
Self‐nanostructuring of redox‐active organic small molecules through in situ electrochemical postcrosslinking enabled an aqueous‐processed, stable, fast‐rechargeable organic electrode even with a high active content ratio and mass loading. ABSTRACT Redox‐active organic materials (ROMs) for batteries are emerging as sustainable alternatives to inorganic
