A molecular platform for protein detection and quantification is reported in which recognition has been integrated with direct monitoring of target-protein binding. The platform is based on a versatile 42-residue helix-loop-helix polypeptide that dimerizes to form four-helix bundles and allows site-selective modification with recognition and reporter elements on the side chains of individually addressable

4-carboxy-benzenesulfonamide or 4-chloro-3-sulfamoyl benzoic acid with carboxy-protected amino acids/dipeptides, or aromatic/heterocyclic sulfonamides/mercaptans afforded the corresponding benzene-carboxamide derivatives. These were tested as inhibitors of three carbonic anhydrase (CA) isozymes, CA I, II and IV. Some of the new derivatives showed affinity in the low nanomolar range for isozymes CA II
Solid-phase affinity labeling of target proteins with the specifically designed chemical tools selectively and effectively furnished the labeled target proteins without the need for tedious manipulations.
