Abstract

PtIV mixed chloride complexes with purine or pyrimidine and imidazole derivatives have been prepared and characterized. The compounds have general formula [Pt(L1)(L2)Cl4], where L1=purine (pur) or pyrimidine (pyr) and L2=N-methylimidazole (N-MeIm),N-ethylimidazole (N-EtIm) orN-propylimidazole (N-PropIm), except for the complex [Pt(pur)(pyr)Cl4]. The nitrogen bases act as monodentate ligands coordinatedvia nitrogen. The far i.r. and electronic reflectance spectra indicate a hexacoordinate geometry. The complexes competitively inhibit lentil amine oxidase, with highest inhibition for [Pt(pur)(N-EtIm)Cl4].
