Open full text 14 citations

Abstract

Co(II); Zn(II) and Cu(II) complexes of two new sulfonamide carbonic anhydrase (CA) inhibitors, derivatives of thienothiopyran-2-sulfonamide, were prepared and characterized by analytic, spectroscopic, magnetic and conductimetric measurements. The new complexes are more potent CA inhibitors than the parent sulfonamides, with IC(50) values around 0.1 nM, against isozyme CA II.
