Abstract
Arene-ruthenium(II) complexes with carbothioamidopyrazoles at the C-2 and C-5 positions have been recognized as chemotherapeutic agent alternatives to cisplatin and its oxaliplatin analogs. The aim of this study was to continue research on the biological aspect of arene-ruthenium(II) complexes and their anticancer activity. The present paper includes an additional 12 new tumor cells, analyzed by MTT, and employs a series of extended bioassays to better understand their potential mechanism of antitumor activity. The following tests were conducted: membrane permeability studies, intramolecular reactive oxygen and nitrogen species (ROS/RNS) assays, mitochondrial potential changes, DNA analysis by comet assay using the electrophoresis method, measurement of cleaved PARP protein levels, and determination of apoptotic and necrotic cell fractions by fluorescence microscopy. Additionally, the article presents lipophilicity studies based on RP-TLC and molecular docking studies. We hope that the presented data will prove useful in practical treatment, especially for patients with cancer.

Abstract
To meet the demand for alternatives to commonly used antibiotics, this paper evaluates the antimicrobial potential of arene-ruthenium(II) complexes and their salts, which may be of value in antibacterial treatment. Their antimicrobial activity (MIC, MBC/MFC) was examined in vitro against Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis, Pseudomonas aeruginosa, Proteus vulgaris and Candida albicans and compared with classic antibiotics used as therapeutics. Selected arene-ruthenium(II) complexes were found to have synergistic effects with oxacillin and vancomycin against staphylococci. Their bactericidal effect was found to be associated with cell lysis and the ability to cut microbial DNA. To confirm the safety of the tested arene-ruthenium(II) complexes in vivo, their cytotoxicity was also investigated against normal human foreskin fibroblasts (HFF-1). In addition, the antioxidant and thus pro-health potential of the compounds, i.e., their nonenzymatic antioxidant capacity (NEAC), was determined by two different methods: ferric-TPTZ complex and DPPH assay.

Abstract
Radiotherapy is among the most important methods for breast cancer treatment. However, this method's effectiveness is limited by radioresistance. The aim of this study was to investigate whether the stilbene derivatives piceid, resveratrol, and piceatannol have a radiosensitising effect on breast cancer cells (MCF-7). The conducted research enabled us to determine which of the tested compounds has the greatest potential in sensitising cells to ionising radiation (IR). Among the stilbene derivatives, resveratrol significantly increased the effect of IR. Resveratrol and IR used in combination had a higher cytotoxic effect on MCF-7 cells than using piceatannol, piceid, or radiation alone. This was due to a significant decrease in the activity of antioxidant enzymes, which resulted in the accumulation of formed reactive oxygen species (ROS). The effect of resveratrol and IR enhanced the expression of apoptotic genes, such as Bax, p53, and caspase 8, leading to apoptosis.

Abstract
A series of 3-benzylidenechrmanones 1, 3, 5, 7, 9 and their spiropyrazoline analogues 2, 4, 6, 8, 10 were synthesized. X-ray analysis confirms that compounds 2 and 8 crystallize in a monoclinic system in P21/n space groups with one and three molecules in each asymmetric unit. The crystal lattice of the analyzed compounds is enhanced by hydrogen bonds. The primary aim of the study was to evaluate the anti-proliferative potential of 3-benzylidenechromanones and their spiropyrazoline analogues towards four cancer cell lines. Our results indicate that parent compounds 1 and 9 with a phenyl ring at C2 have lower cytotoxic activity against cancer cell lines than their spiropyrazolines analogues. Analysis of IC50 values showed that the compounds 3 and 7 exhibited higher cytotoxic activity against cancer cells, being more active than the reference compound (4-chromanone or quercetin). The results of this study indicate that the incorporation of a pyrazoline ring into the 3-arylideneflavanone results in an improvement of the compounds' activity and therefore it may be of use in the search of new anticancer agents. Further analysis allowed us to demonstrate the compounds to have a strong inhibitory effect on the cell cycle. For instance, compounds 2, 10 induced 60% of HL-60 cells to be arrested in G2/M phase. Using a DNA-cleavage protection assay we also demonstrated that tested compounds interact with DNA. All compounds at the concentrations corresponding to cytotoxic properties are not toxic towards red blood cells, and do not contribute to hemolysis of RBCs.

Abstract
Indoxyl sulfate (IS) is a uremic toxin that has been associated with inflammation and oxidative stress as well as with the progression of chronic kidney disease (CKD). IS is a protein metabolite that is concentrated in the serum of CKD patients. IS is a well-known uremic toxin, but there are very few reports on the effect of IS on cells including mononuclear cells (MNCs). We hypothesized that a high concentration of IS in CKD patients may induce changes in redox balance in the in vitro cells exposed. In the present study, we investigated the effect of IS on free radical production, antioxidant capacity, and protein damage in the mononuclear blood cells. As already determined, the concentrations (0.2 or 1 mM) of IS used in this study do not affect the survival rate of MNCs. For both the concentrations of IS, there was an increase in superoxide and nitric oxide and a release of other reactive oxygen species (ROS) inside the cells, as measured using fluorescent probes. However, an increase in other ROS as indicated by H2DCF-DA was found only for 1 mM of IS. Moreover, a decrease in the non-enzymatic antioxidant capacity and an increase in the superoxide dismutase activity after incubation of the cells with IS were observed. Furthermore, we found an increase in the levels of carbonyl compounds and peroxides in the cells treated with both the concentrations of IS. The obtained results show that IS induces oxidative stress and a decrease in antioxidant defense in cells leading to lipid and protein damage.

Abstract
Three gold(I) complexes of alkynyl chromones were synthesized and characterized. The single-crystal X-ray structure analysis of a dinuclear compound and of a flavone derivative exhibit a typical d10 gold(I)-alkynyl linear arrangement. All complexes were evaluated as anticancer and antibacterial agents against four human cancer cell lines and four pathogenic bacterial strains. All compounds show antiproliferative activity at lower micromolar range concentrations. Complex 4 showed a broad activity profile, being more active than the reference drug auranofin against HepG2, MCF-7 and CCRF-CEM cancer cells. The cellular uptake into MCF-7 cells of the investigated complexes was measured by atomic absorption spectroscopy (AAS). These measurements showed a positive correlation between an increased cellular gold content and the incubation time of the complexes. Unexpectedly an opposite effect was observed for the most active compound. Biological assays revealed various molecular mechanisms for these compounds, comprising: (i) thioredoxin reductase (TrxR) inhibition, (ii) caspases-9 and -3 activation; (iii) DNA damaging activity and (iv) cell cycle disturbance. The gold(I) complexes were also bactericidal against Gram-positive methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) bacterial strains, while showing no activity against the Gram-negative Escherichia coli bacterial strain.

Abstract
There is a current need for novel therapeutic strategies for the treatment of chronic lymphocytic leukemia (CLL), a still incurable hematological cancer involving mainly deregulated apoptosis. The purpose of the present study was to determine ex vivo the effect of the synthetic statin, atorvastatin, a known cholesterol-lowering drug, on peripheral blood mononuclear cells obtained from CLL patients. Using flow cytometry, we investigated the viability and induction of apoptosis in leukemic cells exposed to statin by the Vybrant apoptosis assay kit #4, compared with untreated control cells. We also examined the expression levels of apoptosis-regulatory proteins (Mcl-1, Bcl-2 and Bax), as well as products of the expression/proteolysis of lamin B, poly(ADP-ribose) polymerase‑1 (PARP‑1) and p27Kip1 by western blot analysis. Moreover, the number of sub-G1 cells and DNA fragmentation in atorvastatin-treated leukemic cells were examined by flow cytometry and agarose gel electrophoresis, respectively. The obtained results indicated that CLL cells ex vivo were extremely sensitive to atorvastatin. The cytotoxic effect of this statin was caused by the induction of apoptosis in the leukemic cells. The induction of apoptosis in the drug-treated model cells was confirmed by the reduction or proteolysis of apoptotic markers, such as PARP-1, lamin B and p27Kip1, the increase in the number of sub-G1 cells and DNA ladder formation. During atorvastatin-triggered apoptosis, changes in the expression levels of mitochondrial outer membrane permeability regulatory proteins of the Bcl-2 family were also observed. Ex vivo promising data indicate the strong cytotoxic and pro-apoptotic potential of atorvastatin against leukemic cells, but not normal cells. The obtained data suggest that atorvastatin be considered as a therapeutic option for the treatment of CLL.
