Ct. Supuran et al., CARBONIC-ANHYDRASE INHIBITORS .22. 4-TOLUENESULFONYLHYDRAZIDE COMPLEXES WITH NI(II) AND PD(II) ARE DUAL ISOZYME-II INHIBITORS, Revue Roumaine de Chimie, 41(3-4), 1996, pp. 337-341
Five coordination compounds of tosylhydrazide (TSH) with Ni(II) and Pd
(II) were prepared and characterized by elemental analysis and spectro
scopic data. Ni(II) is in pseudo-octahedral, whereas Pd(II) in square
planar surrounding in these complexes, and TSH coordinates by means of
the NK2 moiety. The new derivatives proved to be dual, relatively str
ong carbonic anhydrase inhibitors, of the non competitive type.
