Benzenesulfonamide, 98+%, Thermo Scientific Chemicals

Description

Biospecific adsorption of carbonic anhydrase to self-assembled monolayers of alkanethiolates that present benzenesulfonamide groups on gold. Biospecific binding of carbonic anhydrase to mixed sams presenting benzenesulfonamide ligands led to a model system for studying lateral steric effects. Benzenesulfonamide modifications at c-7 of ciprofloxacin change its primary target instreptococcus pneumoniae from topoisomerase iv to gyrase. Polar substitutions in the benzenesulfonamide ring of celecoxib afford a potent 1,5-diarylpyrazole class of COX-2 inhibitors.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
The presence of the benzenesulfonylamido (BS) groups shifted the activity of classic antimicrobial fluoroquinolones from being more active against Gram-negative to Gram-positive strains. Biospecific adsorption of carbonic anhydrase to self-assembled monolayers of alkanethiolates that present benzenesulfonamide groups on gold. Biospecific binding of carbonic anhydrase to mixed sams presenting benzenesulfonamide ligands led to a model system for studying lateral steric effects. In engineering the specificity of antibacterial fluoroquinolones, benzenesulfonamide modifications at c-7 of ciprofloxacin change its primary target instreptococcus pneumoniae from topoisomerase iv to gyrase. Polar substitutions in the benzenesulfonamide ring of celecoxib afford a potent 1,5-diarylpyrazole class of COX-2 inhibitors.

Solubility
Soluble in methanol (25 mg/ml), and water (4.3 mg/ml at 16°C).

Notes
Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents.
