Complexes With Biologically Active Ligands. Part 10 Inhibition of Carbonic Anhydrase Isozymes I and II With Metal Complexes of Imidazo[2,1-b ]-1,3,4-Thiadiazole-2-Sulfonamide.
THE TITLE COMPOUND WAS PREPARED BY AN IMPROVED VARIANT OF THE LITERATURE PROCEDURE, AND METAL COMPLEXES CONTAINING ITS ANION AND THE FOLLOWING METAL IONS: Zn(II), Cd(II), Hg(II), Co(II), Ni(II), Cu(II), V(IV), Fe(III) and Ag(I) were synthesized and characterized by standard procedures (elemental analysis; IR, electronic, NMR and EPR spectroscopy; TG, magnetic and conductimetric measurements). The parent sulfonamide and its metal complexes are potent inhibitors of two carbonic anhydrase (CA) isozymes, CA I and II, and they might possess applications as selective cerebrovasodilating agents.
