Applicazioni

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.

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

Dimaleimide fluorogens are being developed for application to fluorescent protein labeling. In this method, fluorophores bearing two maleimide quenching groups do not fluoresce until both maleimide groups have undergone thiol addition reactions with the Cys residues of the target protein

A novel squaraine dye (SQ) exhibits improved fluorescence response toward protein detection by incorporation of a zwitterionic structure. With the aid of a dansylamide (DNSA) substituent, the new probe (DNSA-SQ) exhibits remarkable selectivity in binding to site I (a specific
