Abstract

Reaction of EDTA/DTPA dianhydride with aromatic/heterocyclic sulfonamides afforded a series of derivatives incorporating polyaminopolycarboxylate tails and benzenesulfonamide or 1,3,4-thiadiazole-2-sulfonamide heads. These compounds have been used as ligands to prepare Cu(II) complexes. Both parent sulfonamides as well as their copper complexes behaved as potent inhibitors of four carbonic anhydrase (CA, EC 4.2.1.1) isoforms, the cytosolic CA I and II, and transmembrane CA IX and XII. Some Cu(II) complexes showed subnanomolar affinities and some selectivity for the inhibition of the tumor-associated isoforms IX and XII and might be used as PET hypoxia markers of tumors.
