AB  - The biological activity of Cd compounds has been investigated scarce since Cd has been recognized as a human carcinogen. However, the toxicity of cadmium is comparable to the toxicity of noble metals such as Pt and Pd. The paradigm of metal toxicity has been challenged suggesting that metal toxicity is not a constant property, yet it depends on many factors like the presence of appropriate ligands. Studies on anticancer activity of cadmium complexes showed that the complexation of various ligands resulted in complexes that showed better activities than approved drugs. In the present study, cadmium complexes with biologically potent thiazolyl/selenazoyl-hydrazone ligands have been prepared, and tested for their activity against different types of tumor cell models. The complexation of ligands with Cd(II) resulted in a synergistic effect. The antiproliferative activity study revealed that all complexes are more active compared to 5-fluorouracil and cisplatin. The mechanism of tumor cell growth inhibition reveal that selenium-based compounds induce cell death in T-47D (gland carcinoma) cells through apoptosis via caspase-3/7 activation. Additionally, their pro-apoptotic effect was stronger compared to etoposide and cisplatin. Nuclease activity, detected by gel electrophoresis, may be the possible mechanism of anticancer action of investigated complexes.

AB  - The first complexes of 2-pyridylthiocyanate (L) and silver nitrate (1) and perchlorate (2) were prepared
and characterized by a single crystal X-ray analysis. The common structural motif of both 1 and 2 is coordination
of two L molecules via pyridine nitrogen atom to Ag(I). In order to properly describe the nature
of coordinative bonds in 1 and 2, as well as crystal packings in respective structures, a Quantum Theory of
Atoms in Molecule topological analysis was performed. Coordinated nitrate ion provides more electron
density to Ag(I) in comparison to perchlorate ion. Additional electron density in the case of 2 was provided
by the coordination of third L molecule via thiocyanate nitrogen atom resulting in a 1D polymeric
structure. Detailed computational analysis of intermolecular interactions, as well analysis of interactions
between pyridine ring and –SCN group was performed. Antiproliferative activity of monomeric compound
1 was found to be better than of cisplatin on three out of four studied human cancer cell lines.
Docking studies indicate intercalation as a major binding mode of 1 to DNA, while human serum albumin
was revealed as possible carrier for distribution of 1 in the blood stream.
