WHITE TO OFF-WHITE GRANULAR CRYSTALLINE POWDER | [Uses]
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. | [Definition]
ChEBI: Benzenesulfonamide is a sulfonamide. | [Preparation]
Benzenesulfonamide is obtained by amination of benzenesulfonyl chloride. | [Synthesis Reference(s)]

benzenesulfonamide, the amide of benzenesulfonic acid, has been used to produce various derivatives, especially those used as intermediates in the synthesis of photochemicals, dyes, disinfectants, as well as pharmaceuticals. | [Biochem/physiol Actions]
Benzenesulfonamide is an inhibitor of human carbonic anhydrase B. Benzenesulfonamide derivatives are effective in the treatment of proliferative diseases such as cancer. It is used in the synthesis of dyes, photochemicals and disinfectants. | [Safety Profile]
Moderately toxic by ingestion andintraperitoneal routes. When heated to decomposition itemits very toxic fumes of SOx and NOx. | [in vitro]
in a previous study, a series of n-aryl-β-alanine- and diazo-derivatives of benzenesulfonamide were designed, synthesized, and their binding affinities to carbonic anhydrases (ca) i, ii, vi, vii, xii, and xiii was investigated by the use of isothermal titration calorimetry and fluorescent thermal shift assay. the results indicated that 4-substituted diazobenzenesulfonamides were found to be most potent ca binders among the synthesized derivatives. in addition, the majority of the n-aryl-β-alanine derivatives had better affinity for ca ii while diazobenzenesulfonamides showed nanomolar affinities towards ca i isozyme. moreover, the x-ray crystallographic data showed the binding modes of both derivative groups [1]. | [in vivo]
in the rat cpe model, the most potnet benzenesulfonamide indole derivative at 10 mg/kg in the mc/tw formulation displayed oral efficacy. moreover, this compound, when administered in another preferred, minimal formulation in the same in vivo model, demonstrated superior oral efficacy to the lead phenylmethane sulfonamide way-196025 orally administered in a lipid-based formulation. in addition, this benzenesulfonamide indole derivative was also orally efficacious at 1 mg/kg by attenuating both lar and the associated ahr to aerosolized carbachol in naturally sensitized sheep, which had been challenged through the airways with a. suum antigen [2]. | [References]
