AB  - FETPY, an organo-diiron(I) complex, showed strong cytotoxicity across a panel of human and mouse cancer cell lines, combined with an outstanding selectivity compared to nonmalignant cells. Enhanced iron uptake in aggressive, low-differentiated cell lines, caused membrane lipid peroxidation, which resulted in ferroptosis in human ovarian cancer cells. FETPY induced significant morphological changes in murine B16–F1 and B16–F10 melanoma cells, leading to senescence and/or trans-differentiation into Schwann-like cells, thus significantly reducing their tumorigenic potential. Additionally, FETPY substantially suppressed tumor growth in low- and high-grade syngeneic melanoma models when administered in a therapeutic regimen. FETPY is featured by satisfactory water solubility (millimolar range), an amphiphilic character (Log Pow = −0.17), and excellent stability in a biological medium (DMEM). These important requisites for drug development are rarely met in iron complexes investigated so far as possible anticancer agents. Overall, FETPY holds promise as a safe and potent targeted antitumor agent.

AB  - Лекови на бази метала се деценијама користе у терапији рака. Нажалост, њихова ефикасност је обично праћена значајном токсичношћу и због тога постоји стална потреба за развојем лекова са побољшаним безбедносним профилом. Гвожђе је важан елемент са строго регулисаним метаболизмом и игра кључну улогу у многим физиолошким процесима у организму, попут раста и развоја, што је посебно важно када су у питању ћелије рака. Пошто имају повећане потребе за гвожђем у односу на здраве ћелије, може се очекивати да ћелије рака буду осетљивије на третман једињењима гвожђа од здравих ћелија. У овој студији, испитан је цитотоксични ефекат бинуклеарних једињења гвожђа са изоцијанидним лигандом (Xyl-NC, XylNC+DMAP, Ind-NC) на ћелијама рака хуманог порекла: А2780 рак јајника, MCF-7 рак дојке и HCT116 колоректални карцином in vitro. Третман испитиваним једињењима је смањио вијабилитет свих ћелија рака, док су А2780 одабране за даље истраживање као најосетљивије. Показало се да третман ћелија рака јајника бинуклеарним једињењима гвожђа са изоцијандним лигандима индукује фероптозу, ћелијску смрт изазвану липидном пероксидацијом зависном од гвожђа. Изненађујуће, фероптоза је праћена инхибицијом продукције радикала који узрокују оксидативни и нитрозативни стрес - водоник пероксида и пероксинитрита. Поред тога, показало се да третман свим једињењима узрокује аутофагију ћелија рака јајника. Третман у комбинацији са инхибитором аутофагије 3-метил аденином додатно смањује вијабилитет ћелија, што сугерише да детектована аутофагија има цитопротективну улогу.

AB  - Metal-based drugs have been used as cancer therapeutics for decades. Unfortunately, their efficacy usually comes with significant toxicity and there is a constant need for the development of drugs with improved safety profile. Iron is an important element with tightly regulated metabolism and plays crucial role in many physiological processes in the body, like growth and development, which is particularly important for cancer cells. Since they have increased iron demands compared to healthy cells, it is expected that they could be more susceptible to treatment with iron compounds than healthy cells. In the present study, the cytotoxic effect of diiron compounds with isocyanide ligands (Xyl-NC, XylNC+DMAP, Ind-NC) was investigated on human cancer cell lines: A2780 ovarian cancer, MCF-7 breast cancer, and HCT116 colorectal carcinoma in vitro. Treatment with experimental compounds decreased the viability of all cancer cell lines, while A2780 was selected for further investigation as the most sensitive one. It was shown that treatment of A2780 cells with diiron compounds with isocyanide ligands caused ferroptosis, cell death induced by iron-dependent lipid peroxidation. Surprisingly, ferroptosis was accompanied by the scavenging of radicals causing oxidative and nitrosative stress - hydrogen peroxide and peroxynitrite. Additionally, all 3 compounds induced autophagy in A2780 cells. Co-treatment with the autophagy inhibitor 3-methyl adenine further decreased cell viability, suggesting that detected autophagy had cytoprotective role. Furthermore, treatment with investigated compounds significantly inhibited the proliferation of A2780 cells. Results obtained in this study indicate that diiron compounds with isocyanide ligands could become promising agents for cancer treatment and therefore, require additional attention and further biological assessment.

AB  - Background: Iron is an important trace element with a broad range of functions in diverse physiological processes and tightly regulated metabolism. Over the years, numerous studies have indicated that cancer cells exhibit an iron-seeking phenotype, meaning they have higher demands for iron than healthy cells. This feature may serve as a foundation for a new approach to cancer therapy. In order to develop anticancer drug with improved efficacy, higher selectivity and reduced toxicity, a new organo-diiron complex with a bridging thiocarbyne ligand (FeSDAP) was synthesized. Material and Methods: The cytotoxic effect of FeSDAP was investigated on mouse cancer cell lines (B16-F1 low-invasive melanoma, B16-F10 high-invasive melanoma and 4T1 breast cancer), as well as on mouse embryonic fibroblasts (NIH-3T3). For investigation of its mechanism of action, flow cytometry and light microscopy were used. To investigate how 72h long exposure to DMAP in vitro affect the potential of B16-F1 and B16-F10 cells to form tumor in vivo, respective subcutaneous synegenic models in C57BL/6 mice were used. Results and Conclusions: Treatment with FeSDAP decreased viability of all cells after 72 hours, with significantly less potent effect on embryionic fibroblasts compared to cancer cells, suggesting FeSDAP may possess selectivity towards malignant phenotype. Melanoma cells were almost equally sensitive to the treatment, but more sensitive than breast cancer cells, so both B16-F1 and B16-F10 were selected for further comparative investigation. Treatment with FeSDAP inhibited proliferation of melanoma cells and caused substantial change in their morphology, which was even more pronounced when it comes to B16-F10 cells. After microscopic evaluation, it was shown that melanoma cells went into senescence. Prominent morphological change of B16-F10 cells was caused by transdifferentiation into Schwann Cell-Like Cells. Further investigation of tumorigenic potential of treated melanoma cells in mice showed that the average tumor size in the groups that received treated cells was significantly smaller, suggesting that melanoma cells have persistently reduced potential to form tumor after single in vitro treatment with FeSDAP. Ultimately, these results strongly indicate that investigated diiron thiocarbyne complexes may display a promising antitumor potential that will be investigated in more detail.

AB  - To improve safety and efficacy of conventional chemotherapeutics, it is important to target
cancer cells more selectively. Potential strategies could arise from differences in iron
metabolism between healthy and cancer cells, based on cancer cells high demands for iron.
Their, so-called, “iron addiction” sets a foundation for new therapeutic approach. In this
study, the cytotoxic effect of three diiron carbonyl complexes with a bridging thiocarbyne
ligand was evaluated on different human cancer cell lines (HCT116 colorectal carcinoma,
MCF-7 breast cancer and A2780 ovarian cancer), as well as on human embryonic lung
fibroblasts (MRC-5), which were used for selectivity assessment. The most potent
compound (FETPY) decreased viability of all cancer cell lines in dose-dependent manner,
while A2780 cells emerged as the most sensitive. Therefore, they were selected for further
investigation. On the other hand, the effect of FETPY on lung fibroblasts viability was
remarkably less potent, showing its great selectivity towards malignant phenotype.
Additionally, it was shown that intracellular iron concentration was much higher in A2780
than in MRC-5 cells after treatment with FETPY. Viability decrease of A2780 cells was a
consequence of cell death – ferroptosis, caused by iron-dependent lipid peroxidation and
membrane damage. Oxidative stress that caused ferroptosis evolved from intensive
production of nitric oxide and superoxide anion. Controversially, it was followed with
scavenging of hydrogen peroxide and peroxynitrite. Treatment with FETPY also caused
significant decrease of A2780 cells division rate. Overall, these results indicate that the
considered diiron derivatives show great potential for further investigation in cancer
treatment.

AB  - Piano-stool iridium complexes based on the pentamethylcyclopentadienyl ligand (Cp*)
have been intensively investigated as anticancer drug candidates and hold much promise in this
setting. A systematic study aimed at outlining the effect of Cp* mono-derivatization on the an tiproliferative activity is presented here. Thus, the dinuclear complexes [Ir(η

(R = Me, 1a; R = H, 1b; R = Pr, 1c; R = 4-C6H4F, 1d; R = 4-C6H4OH, 1e), their 2-phenylpyridyl
mononuclear derivatives [Ir(η

(κS-Me2S=O)] (3) were synthesized, structurally characterized, and
assessed for their cytotoxicity towards a panel of six human and rodent cancer cell lines (mouse
melanoma, B16; rat glioma, C6; breast adenocarcinoma, MCF-7; colorectal carcinoma, SW620 and
HCT116; ovarian carcinoma, A2780) and one primary, human fetal lung fibroblast cell line (MRC5).
Complexes 2b (R = H) and 2d (4-C6H4F) emerged as the most active ones and were selected for further
investigation. They did not affect the viability of primary mouse peritoneal cells, and their tumorici dal action arises from the combined influence on cellular proliferation, apoptosis and senescence. The
latter is triggered by mitochondrial failure and production of reactive oxygen and nitrogen species.
