Anwendung

5-(Dimethylamino)-1-naphthalenesulfonamide (DNSA) was used as starting reagent in the synthesis of 2,6-disubstituted pyridines, 6-substituted 2,2′-bipyridines and 6,6′-disubstituted 2,2′-bipyridines. It was also used as fluorescent probe in the determination of concentration of human carbonic anhydrase II-DNSA in solutions.

[structure: see text] 2,6-Disubstituted pyridines, 6-substituted 2,2'-bipyridines, and 6,6'-disubstituted 2,2'-bipyridines are readily prepared under mild conditions from 5-(dimethylamino)-1-naphthalenesulfonamide chloride (DANS-Cl) and chloromethyl-nitronyl nitroxide (CH(2)Cl-NIT) starting materials and adequately functionalized building blocks. The syntheses of the pyridine molecules bearing two radicals

This paper describes inhibitors for human carbonic anhydrase II (HCAII, EC 4.2.1.1) that bind with nanomolar dissociation constants. These inhibitors were developed by exploiting interactions with hydrophobic "patches" in the lip of the active site of this enzyme. These patches

The binding interactions of small molecules with carbonic anhydrase II were used as model systems to compare the reaction constants determined from surface- and solution-based biophysical methods. Interaction data were collected for two arylsulfonamide compounds, 4-carboxybenzenesulfonamide (CBS) and 5-dimethyl-amino-1-naphthalene-sulfonamide (DNSA)
