Abstract
The synthesis of new Pt(II) and Pd(II) complexes with 1-aminomethyl-2-naphtol ligands has been first performed. The adducts of [PtCl4]2- and [PdCl4]2- anions with the 1-aminomethyl-2-naphtol NH cation were synthesized. The structure for four Pt (Pd)-containing compounds was investigated using X-ray diffraction. The obtained compounds were examined for in vitro cytotoxic activity against Jurkat and K562 human leukemia cells, lymphoma U937cells, A2780 and the cisplatin-resistant A2780cis lines of human ovarian cancer, and normal fibroblasts. Study of induction of apoptosis and the effect of new palladium and platinum complexes on the cell cycle was carried out. The cells showed a higher sensitivity to Pt(II) compounds than to Pd(II) ones. All the synthesized metal complexes show much more antitumor activity compared with a platinum-containing cisplatin drug.
