New sulfonamides containing organometallic-acylhydrazones: synthesis, characterisation and biological evaluation as inhibitors of human carbonic anhydrases

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
A series of organometallic acylhydrazones was prepared, incorporating Re(CO)3, Mn(CO)3 and ferrocenyl moieties, which were subsequently reacted with amino-sulfonamides in order to obtain carbonic anhydrase (CA, EC 4.2.1.1) inhibitors possessing ...

Expedient Discovery of a Metallaphotoredox Cyanomethylation for Synthesizing α‐Aryl Nitriles

open access: yesChemistry – A European Journal, EarlyView.
A metallaphotoredox cyanomethylation reaction has been developed for the synthesis of valuable α‐aryl nitrile intermediates. The methodology was successfully applied to diverse medicinally‐relevant substrates, providing an expedient route to anti‐cancer Senexin compounds, while also removing the need for toxic cyanide reagents. The mechanism was probed

Photoinduced Copper‐Catalyzed para‐Selective C–H S‐Arylation of Benzylic Oxime Carbonates with Sulfenamides

open access: yesChinese Journal of Chemistry, EarlyView.
We present a dual copper/photoredox catalytic system that enables the para‐selective C–H functionalization of benzyl alcohols with sulfenamides. This approach facilitates the para‐selective C–H sulfilimination of benzylic oxime carbonates through an orchestrated sequence involving photoinduced decarboxylation/dearomatization of oxime carbonates, copper‐

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

Enhanced Photocatalytic Antibiotic Micropollutants Removal Resulting From a Synergism Between Cu Single Atoms and Carbon Vacancies on Graphitic Carbon Nitride

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Scheme of the synergistic degradation for antibiotic micropollutants in the Cu/ag‐C3N4 system. Photocatalytic processes driven by visible‐light irradiation offer a sustainable means of micropollutants removal from aquatic environments without the addition of reagents.

Pathogenicity and Antimicrobial-Resistance Profiles of Escherichia coli Isolated From Faeces of Tibetan Pigs Reared Under Intensive Conditions. [PDF]

open access: yesVet Med Sci
Tibetan pig farms host diverse Escherichia coli strains that resist multiple antibiotics and carry important disease genes, such as astA. These traits jump easily between bacterial groups, marking intensive pig production as a key reservoir and signalling the need for integrated animal–human surveillance and more careful antibiotic use.

Antibacterial Activity of Heteropolytungstates Against Proteus mirabilis

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
We investigated the in vitro antibacterial activity of several heteropolytungstates against P. mirabilis, a drug‐resistant pathogen. All tested polyanions inhibited bacterial growth, with the Preyssler–Pope–Jeannin polyanion P5W30 exhibiting the highest activity (MIC = 0.78 mg/mL).

The interaction between mercury(II) and sulfathiazole

open access: yesQuímica 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.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

1,1‐Disubstituted Vinylbromides: Versatile Building Blocks for the Synthesis of Nitrogen‐Containing Heterocycles

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
1,1‐Disubstituted vinylbromides are key intermediates for constructing nitrogen‐containing heterocycles. This review provides an overview of the synthetic applications of 1,1‐disubstituted vinylbromides and summarizes recent developments in reaction methodologies, mechanistic insights, and the structural diversity of N‐heterocyclic compounds accessible
