Application

Benzenesulfonamide was used to develop analytical method for simultaneous determination of benzotriazole, benzothiazole and benzenesulfonamide contaminants in environmental waters.

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.

Preparation Note

Benzenesulfonamide dissolves in methanol at a concentration of 25 mg/ml to form a clear, colourless solution.

Thirteen new 2-pyrazoline derivatives bearing benzenesulfonamide moiety (2a-m) were synthesized by condensing appropriate chalcones with 4-hydrazinonbenzenesulfonamide hydrochloride and tested for anticancer and anti-inflammatory actions. According to the protocol of the National Cancer Institute (NCI) in vitro disease-oriented human cells screening

C5-Ethynylbenzenesulfonamide-modified nucleotide (EBNA) was investigated as substrate of various DNA polymerases. The experiments revealed that KOD, Phusion and Klenow DNA polymerases successfully accepted EBNA-T nucleotide as a substrate and yielded the fully extended DNA. KOD DNA polymerase was found to

A series of [(2-pyrimidinylthio)acetyl]benzenesulfonamides were designed and synthesized. Their binding affinities as inhibitors of several recombinant human carbonic anhydrase (CA) isozymes were determined by isothermal titration calorimetry (ITC) and thermal shift assay (TSA).

The FT-IR and FT-Raman spectra of (E)-N-carbamimidoyl-4-((4-methoxybenzylidene)amino)benzenesulfonamide were recorded and analyzed. Geometry and harmonic vibrational wavenumbers were calculated theoretically using Gaussian 03 set of quantum chemistry codes. Calculations were performed at the Hartree-Fock (HF) and density functional theory (DFT) levels
