Rational Design of Ni3+‐Rich Nickel Nitride Enables Paired Electrooxidation of Sterol and Hydrogen Evolution in a Flow Electrolyzer

open access: yesAdvanced Science, EarlyView.
The rational design of Ni3+‐rich active sites on nickel nitride nanosheets via Pd‐induced electronic modulation, which was employed in the electrooxidation of sterol coupled with H2 production in a large flow electrolyzer. This work offers a novel strategy for the design and synthesis of highly efficient electrocatalysts and electrolyzers toward the ...

Modulation of Tau Protein Neurotoxic Hallmarks by Novel σ1R Agonists/HDAC Inhibitor Dual‐Acting Compounds [PDF]

open access: yesChemMedChem
This study explores the development of dual‐acting compounds combining σ1R agonists and histone deacetylase inhibitors (HDACi). Key findings include compound 2d and 3a's high affinity for σ1R and favorable pharmacokinetic profile and an in vivo determined σ1R agonist profile by reversing the effect of the σ1R antagonist BD‐1063.

Synthesis of dihydropyridine and piperidine derivatives via an unexpected reaction of pyridine with acetyl chloride [PDF]

open access: yes, 2013
Acetyl chloride reacts with pyridine to give a mixture of N-acetyl-1,4- and 1,2-dihydropyridyl acetic acid (1a,b) after water quenching. The reactioninvolves the formation of a zwitterionic ketene enolate intermediate which results from deprotonation of

Correlations between electrochemical behaviors and DNA photooxidative properties of non-steroïdal anti-inflammatory drugs and their photoproducts [PDF]

open access: yes, 2012
Alkali-labile lesion to DNA photosensitized, via an electron transfer mechanism, by three non-steroidalanti-inflammatorydrugs (NSAIDs), ketoprofen, tiaprofenic acid and naproxen and their photoproducts during drug photolysis, was investigated using 32P ...

Kontrollierter Transport und lichtinduzierte Freisetzung von Magic Spot Nukleotiden in Escherichia coli

open access: yesAngewandte Chemie, EarlyView.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a
