Abstract
3,5‐Dimethyl‐5‐(4‐pyridyl)hydantoin (L) and its platinum(II) and platinum(IV) complexes with the general formula cis‐[PtL~2~X~2~] · n H~2~O and [PtL~2~Cl~4~], where XCl, I and n = 2‐4 were synthesized. A new Pt(IV) complex with 5‐methyl‐5‐(4‐pyridyl)hydantoin (L′) with the formula cis‐[Pt(L′)~2~Cl~2~(OH)~2~] · 5 H~2~O was also synthesized. The novel compounds were characterized by elemental analysis, IR, ^1^H‐, ^13^C‐, ^195^Pt‐NMR spectra and molar conductivity. The cytotoxic effects of these complexes were examined on three human tumor cell lines by MTT‐dye reduction assay. These four new Pt(II) and Pt(IV) complexes and a set of another twelve Pt(II), Pt(IV), and Pd(II) complexes previously synthesized and tested were compiled and a QSAR model was derived in order to direct the further rational synthesis.
