AB  - Copper(II) complexes with the condensation derivative of methyl hydrazinoacetate and 2-acetylpyridine were synthesized. The X-ray crystal structures for both complexes revealed that they are polymerized isomers. A common feature of both complexes is the bidentate coordination of the ligand by one hydrazone and one pyridine nitrogen atom. In the monomeric complex, the copper(II) center is tetracoordinate, whereas dimerization through chlorido bridges results in a pentacoordinate arrangement about the metal ions in the dimer. The electronic and magnetic properties of both complexes are discussed on the basis of their X-ray structures, electron paramagnetic resonance (EPR) spectroscopy studies, and superconducting quantum interference device (SQUID) magnetization measurements combined with DFT calculations. Magnetostructural comparisons with structurally similar copper(II) complexes are also provided, and a possible correlation has been established. The antitumor activities of the Cu-II complexes were investigated against six different cancer cell lines, and the results suggest that the antiglioma action of the dimeric species is based on oxidative-stress-mediated phosphatidylserine externalization and caspase activation, which indicate apoptosis.

AB  - Novel Pd(II) complex with N-heteroaromatic Schiff base ligand, derived from 8-quinolinecarboxaldehyde (q8a) and ethyl hydrazinoacetate (haOEt), was synthesized and characterized by analytical and spectroscopy methods. The structure of novel complex, as well as structures of its quinoline and pyridine analogues, was optimized by density functional theory calculations, and theoretical data show good agreement with experimental results. A cytotoxic action of the complexes was evaluated on cultures of human promyelocytic leukemia (HL-60), human glioma (U251), rat glioma (C6), and mouse fibrosarcoma (L929) cell lines. Among investigated compounds, only complexes with quinoline-based ligands reduce the cell numbers in a dose-dependent manner in investigated cell lines. The observed cytotoxic effect of two isomeric quinoline-based complexes is predominantly mediated through the induction of apoptotic cell death in HL-60 cell line. The cytotoxicity of most efficient novel Pd(II) complex is comparable to the activity of cisplatin, in all cell lines investigated.

AB  - Two novel cadmium(II) complexes with condensation derivatives of 2-acetylpyridine or 2,6-diacetylpyridine with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures of the complexes revealed a bidentate coordination of the 2-acetylpyridine derivative, while the symmetric 2,6-diacetylpyridine derivative was coordinated tridentately. It was found that the oxygen atoms were not coordinated to the cadmium ions, despite the fact that they are the position to form six membered chelate rings. NMR spectroscopy investigations showed that the coordination properties of the ligands do not change in solution. Both complexes possess cytotoxic potential, as determined by the toxicity test to Artemia

AB  - Organometallic Cd(II) compounds have recently attracted attention for their anticancer activity. The interaction of the dinuclear complex of Cd(II) with the condensation product of 2-acetylpyridine and malonic acid dihydrazide, N',N'(2)-bis[(1E)-1-(2pyridyl) ethylidene] propanedihydrazide (Cd(II)H(2)L), with calf thymus DNA (CT-DNA) was monitored by blue shift in UV-vis spectra of the complex. The binding constant of Cd(II) H2L complex with CT-DNA was determined (K(B) = 1.8 x 10(4) M(-1)) and was indicative of minor groove binding. Agarose gel electrophoretic changes in mobility of supercoiled and circular forms of pBR322 and pUC18 plasmids in the presence of the complex suggest that conformational changes in the plasmids occur upon binding of the Cd(II) H2L complex. The Cd(II) H2L complex induced perturbation of the cell cycle phase distribution and an increase in the percentage of cells in the sub-G1 phase of human cervical cancer HeLa cell line and murine melanoma B16 cell line. Immunoblotting analysis showed the overexpression of Bcl-2 protein with the Cd(II)H(2)L complex.

In the complexes, both ligands are coordinated in neutral NN bidentate modes, while the remaining two coordination sites are occupied by chloride.
