Four organometallic η6-arene Ru(ii) architectures (MA1–MA4) have been reported. In vitro anticancer activity of the architectures against human cancer cell lines showed good cytotoxicity where the generation of reactive oxygen species (ROS) is responsible for the cell death.

Cell Death Mechanisms

One of the most promising photosensitizers (PS) used in photodynamic therapy (PDT) is the porphyrin derivative 5,10,15,20-tetra(m-hydroxyphenyl)chlorin (mTHPC, temoporfin), marketed in Europe under the trade name Foscan®. A set of five human cancer cell lines from head and neck and other PDT-relevant tissues was used to investigate oxidative stress and underlying cell death mechanisms of mTHPC-mediated PDT in vitro. Cells were treated with mTHPC in equitoxic concentrations and illuminated with light doses of 1.8–7.0 J/cm2 and harvested immediately, 6, 24, or 48 h post illumination for analyses. Our results confirm the induction of oxidative stress after mTHPC-based PDT by detecting a total loss of mitochondrial membrane potential (Δψm) and increased formation of ROS. However, lipid peroxidation (LPO) and loss of cell membrane integrity play only a minor role in cell death in most cell lines. Based on our results, apoptosis is the predominant death mechanism following mTHPC-mediated PDT. Autophagy can occur in parallel to apoptosis or the former can be dominant first, yet ultimately leading to autophagy-associated apoptosis. The death of the cells is in some cases accompanied by DNA fragmentation and a G2/M phase arrest. In general, the overall phototoxic effects and the concentrations as well as the time to establish these effects varies between cell lines, suggesting that the cancer cells are not all dying by one defined mechanism, but rather succumb to an individual interplay of different cell death mechanisms. Besides the evaluation of the underlying cell death mechanisms, we focused on the comparison of results in a set of five identically treated cell lines in this study. Although cells were treated under equitoxic conditions and PDT acts via a rather unspecific ROS formation, very heterogeneous results were obtained with different cell lines. This study shows that general conclusions after PDT in vitro require testing on several cell lines to be reliable, which has too often been ignored in the past.

Effective Synthesis

In our present work, we displayed an effective synthesis and anticancer activity assessment of some novel 2-hetaryl-3-(5-arylfuran-2-yl)-acrylonitriles. The structures of synthesized substances were determined by 1H NMR spectroscopy and elemental analysis. In vitro anticancer activity assessment on the full panel of about 60 human cancer cell lines showed that received compounds displayed a weak and moderate kind of activity.

This research was conducted to evaluate the anticancer activity of new compounds of benzyl-1,10- phenanthroline derivatives and their selectivity. In vitro anticancer activity of 11 benzyl-1,10-phenanthroline derivatives were conducted on three human cancer cell lines, cervical cancer (HeLa), myeloma (NS-1), and breast cancer (MCF-7) using MTT-based cytotoxicity assay. The cytotoxicity of each compound was assessed to normal Vero cell line by the same method. The in vitro anticancer activity and cytotoxicity was expressed by the concentration inhibiting 50% of the cell growth (IC50), and the selectivity index (SI) was determined by calculating ratio of the IC50 on Vero cell line and the human cancer cell lines. The results showed that among the 11 compounds tested, the (1)-N-(4-butoxybenzyl)-1,10-phenanthrolinium bromide exhibited the best in vitro anticancer activity with an IC50 27.60 ± 2.76 µM on HeLa, 6.42 ± 5.53 µM on NS-1 and 9.44 ± 2.17 µM on MCF-7 cell lines. Its SI were 377.65 ± 39.97 on HeLa, 6158.72 ± 5306.34 on NS-1 and 1140.11 ± 261.85 on MCF-7 cell lines. This study demonstrated that (1)-N-(4-butoxybenzyl)-1,10-phenanthrolinium bromide possessed a potential in vitro anticancer activity on cancer cell lines with high selectivity
