Enantioselective Hydroamination of Alkenes with Sulfonamides Enabled by Proton-Coupled Electron Transfer.

Journal of the American Chemical Society, 2020
An enantioselective, radical-based method for the intramolecular hydroamination of alkenes with sulfonamides is reported. These reactions are proposed to proceed via N-centered radicals formed by proton-coupled electron transfer (PCET) activation of ...

Sulfonamides and trimethoprim [PDF]

Expert Review of Anti-infective Therapy, 2009
Sulfonamides and trimethoprim are inexpensive and effective antibacterial drugs that have been used extensively. The use of sulfonamides for systemic use has, however, decreased dramatically for several years, mainly because of resistance development in pathogenic bacteria and allergic side effects. Also the clinical efficiency of trimethoprim has been

Development of a receptor based signal amplified fluorescence polarization assay for multi-detection of 35 sulfonamides in pork

Food Chemistry: X, 2023
With the increasing focus on food security, a screening method with high-throughput, ultra-sensitivity, and user-friendly operation is urgently needed for monitoring of sulfonamides residues in animal-derived foods.

Enzymatic Transformation and Bonding of Sulfonamide Antibiotics to Model Humic Substances

Journal of Chemistry, 2015
Sulfonamides are consumed as pharmaceutical antibiotics and reach agricultural soils with excreta used as fertilizer. Subsequently, nonextractable residues rapidly form in soil, which has been researched in a couple of studies.

Transfer of Sulfamethazine from Contaminated Beeswax to Honey [PDF]

, 2010
A liquid chromatographic tandem mass spectrometric method for the determination of sulfa drugs in beeswax was developed. When performing residue control on beeswax intended for the fabrication of wax foundations, residues of sulfonamides were found.

Towards a Molecular Level Understanding of the Sulfanilamide-Soil Organic Matter-Interaction [PDF]

Science of the Total Environment 559, 347 (2016), 2016
In-depth understanding of the sorption mechanisms of organic pollutants, like the antibiotic sulfanilamide (SAA), in soil requires a combined experimental and theoretical approach. Therefore, sorption experiments of SAA on well-characterized samples of soil size-fractions were combined with the modeling of SAA-soil-interaction via quantum chemical ...
