Synthesis, spectral characterization of novel Pd(II), Pt(II) π-coordination compounds based on N-allylthioureas. Cytotoxic properties and DNA binding ability.

Four novel Pd and Pt mononuclear π-coordination compounds with general formula [M(HL)Cl], M=Pd, Pt have been synthesized by reaction of [PdCl], [PtCl] anions with N-allyl-4-morpholinethiocarboxamide (HL) and N-Allyl-N'-tert-butylthiourea (HL). All complexes have been characterized by single-crystal X-ray diffraction study and H, C NMR spectroscopy. Cytotoxic, cytostatic and proapoptotic activities of compounds have been determined in vitro on HeLa cell line and compared with cisplatin as etalon drug.

Effect of Pd(II) and Ni(II) coordination compounds with 4-amino-3-mercapto-5-methyl-1,2,4-triazole on the mitochondrial dehydrogenases activity.

Pd(I) and Ni(II) complex compounds: [Pd(AMMT)2]Cl2 (1), [Pd(AMMT)4]Cl2 (2) and [Ni(AMMT)2(H2O)](NO3)2 (3) with 4-amino-3-mercapto-5-methyl-1,2,4-triazole (AMMT) have been synthesized. The spectral characteristics of 1, 2 were studied by 1H (13C) NMR and UV-Vis spectroscopy. X-ray diffraction studies established that all complexes contain the AMMT molecule, which are coordinated to the central metal ion in the thione tautomeric form.
