Pharmaceuticals (Basel) 2023; 17:50. [PMID: 38256884 PMCID: PMC10819265 DOI: 10.3390/ph17010050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 11/20/2023] [Accepted: 11/27/2023] [Indexed: 01/24/2024] Open
Abstract
[Ru(bipy)2(dpphen)]Cl2 (where bipy = 2,2'-bipyridine and dpphen = 2,9-diphenyl-1,10-phenanthroline) (complex 1) is a sterically strained compound that exhibits promising in vitro photocytotoxicity on an array of cell lines. Since lung adenocarcinoma cancer remains the most common lung cancer and the leading cause of cancer deaths, the current study aims to evaluate the plausible effect and uptake of complex 1 on human alveolar carcinoma cells (A549) and mesenchymal stem cells (MSC), and assess its cytotoxicity in vitro while considering its effect on cell morphology, membrane integrity and DNA damage. MSC and A549 cells showed similar rates of complex 1 uptake with a plateau at 12 h. Upon photoactivation, complex 1 exhibited selective, potent anticancer activity against A549 cells with phototoxicity index (PI) values of 16, 25 and 39 at 24, 48 and 72 h, respectively. This effect was accompanied by a significant increase in A549-cell rounding and detachment, loss of membrane integrity and DNA damage. Flow cytometry experiments confirmed that A549 cells undergo apoptosis when treated with complex 1 followed by photoactivation. In conclusion, this present study suggests that complex 1 might be a promising candidate for photochemotherapy with photoproducts that possess selective anticancer effects in vitro. These results are encouraging to probe the potential activity of this complex in vivo.

Abstract
Immature forms of the peptide hormone gastrin have been implicated in the development of colorectal cancer (CRC). The biological activity of glycine-extended gastrin (Ggly) is dependent on the binding of Fe3+ ions in vitro and in vivo. The aim of the present study was to determine the effect of blocking Fe3+ ion binding to Ggly, using Bi3+, In3+ or Ru3+ ions, on the development of intestinal tumors in APCΔ14/+ mice. APCΔ14/+ mice were treated orally with Bi3+, In3+ or Ru3+ ions for up to 60 days, serum trace metals were analyzed by inductively coupled plasma mass spectrometry, and the incidence and size of intestinal tumors were assessed. Bi3+ treatment significantly decreased the number of tumors larger than 3 mm in male mice. In3+ or Ru3+ treatment significantly increased the tumor burden in all animals and In3+ increased the number of tumors larger than 3 mm or 5 mm in male mice alone. The fact that binding of In3+ or Ru3+ ions to Ggly was orders of magnitude stronger than the binding of Bi3+ ions implies that the inhibitory effect of Bi3+ ions is not a consequence of a reduction in Ggly activity. However, further testing of higher doses of Bi3+ ions for longer periods as an oral treatment for intestinal tumors is warranted.

Abstract
Imidazolium trans-tetrachloridodimethylsulfoxideimidazolruthenate(III), NAMI-A, a novel antimetastatic ruthenium complex was investigated towards affinity to transferrin (Tf), whether Tf–Ru adducts might be formed after its intravenous injection. Studies were focused on the holotransferrin due to its preferential binding to transferrin receptor. Here, we showed that holotransferrin is able to bind NAMI-A as readily as apotransferrin. The simulation of biological conditions of human serum performed by application of simplified serum models allowed to analyse ruthenium distribution between transferrin and albumin. The presence of physiological concentration of albumin (ca. 18-fold excess over Tf) resulted in a twofold decrease of ruthenium binding to Tf. Interestingly, the introducing of low-molecular-mass components of serum dramatically increased the ruthenation of Tf. Intermolecular competition binding studies between transferrin and albumin showed that both proteins bound similar amount of ruthenium species. Investigation of NAMI-A binding to Tf in human serum showed that this protein was not the major binding partner for Ru complex. However, in spite of many competing proteins still the ruthenation of Tf was observed. The lack of free Ru species (protein unbounded) after incubation with human serum allowed to make an assumption of high affinity of NAMI-A towards serum proteins.

Abstract
Chemotherapy is a common treatment for leukemia. Ruthenium complexes have shown potential utility in chemotherapy and photodynamic therapy. The identification of new chemotherapeutics agents is critical for further progress in the treatment of leukemia. Ruthenium complexes generally have lower toxicities compared to cisplatin attributed to their specific accumulation in cancer tissues. Based on these evidences, in the present work we studied the cytotoxic activity of the ruthenium(III) compound cis-tetraammine(oxalato)ruthenium(III) dithionate - {cis-[Ru(C2O4)(NH3)4]2(S2O6)} against human chronic myelogenous leukemia cells (K-562) tumor cell line. The tested compound induces cell death in a dose and time dependent manner on K-562 cells. It is found that the effect was improved linearly while prolonging the incubation time. Compared to the cell cycle profiles of untreated cells, flow cytometric analysis indicated the sub-G1 arresting effect of ruthenium compound on K-562 cells. In our study, {cis-[Ru(C2O4)(NH3)4]2(S2O6)} shows a significant increase in tailed cells in any of the concentrations tested compared with negative control. Consequently, the concentration of {cis-[Ru(C2O4)(NH3)4]2(S2O6)} might be associated cytotoxicity with direct effect on K-562 cells DNA. Thus, it can be deducted that ruthenium-based compounds present selectivity to enter both tumor and normal cells. Additional studies are needed to determine the molecular mechanisms of the active components and to evaluate the potential in vivo anticancer activity of the cis-tetraammine(oxalato)ruthenium(III) dithionate.

Abstract
Ruthenium(III) complexes are increasingly attracting the interest of researchers due to their promising pharmacological properties. In the present study, we investigated the ability of cis-(dichloro)tetrammineruthenium(III) chloride to produce lethal effects in human chronic myelogenous leukemia K562 cells. The MTT tetrazolium reduction test and the trypan blue exclusion assay revealed that the IC(50) for the compound after 48 h of incubation with K562 cells was approximately 10.74 and 73.45 microM, respectively. Interestingly, it was observed that this compound exhibits mild cytotoxicity towards MRC-5 human fibroblast cells (IC(50)>383 microM). Flow cytometric analysis revealed that cis-(dichloro)tetrammineruthenium(III) chloride was capable of change cell cycle distribution since the percentage of cells in the G1, S and G2 phases decreased. In addition, treatment with this compound induced apoptotic cell death in K562 cells, demonstrated by increased DNA content in the sub-G1-peak and a significant increase in caspase-3 activity. Assay using cyclosporin A, an inhibitor of the mitochondrial permeability transition pore (MPT) showed that the preincubation of K562 cells with this inhibitor had not effect on cis-(dichloro)tetrammineruthenium(III) chloride induced caspase-3 activation. In summary, cis-(dichloro)tetrammineruthenium(III) chloride displayed a significant cytotoxic effect through cell cycle arrest and apoptotic induction in K562 cells, which suggests that cis-(dichloro)tetrammineruthenium(III) chloride might have therapeutic potential against leukemia.

Abstract
The aim of present study was to verify the in vitro antitumor activity of a ruthenium complex, cis-(dichloro)tetraammineruthenium(III) chloride (cis-[RuCl(2)(NH(3))(4)]Cl) toward different tumor cell lines. The antitumor studies showed that ruthenium(III) complex presents a relevant cytotoxic activity against murine B cell lymphoma (A-20), murine ascitic sarcoma 180 (S-180), human breast adenocarcinoma (SK-BR-3), and human T cell leukemia (Jurkat) cell lines and a very low cytotoxicity toward human peripheral blood mononuclear cells. The ruthenium(III) complex decreased the fraction of tumor cells in G0/G1 and/or G2-M phases, indicating that this compound may act on resting/early entering G0/G1 cells and/or precycling G2-M cells. The cytotoxic activity of a high concentration (2 mg mL(-1)) of cis-[RuCl(2)(NH(3))(4)]Cl toward Jurkat cells correlated with an increased number of annexin V-positive cells and also the presence of DNA fragmentation, suggesting that this compound induces apoptosis in tumor cells. The development of new antineoplastic medications demands adequate knowledge in order to avoid inefficient or toxic treatments. Thus, a mechanistic understanding of how metal complexes achieve their activities is crucial to their clinical success and to the rational design of new compounds with improved potency.

Abstract
Ruthenium compounds in general are well suited for medicinal applications. They have been investigated as immunosuppressants, nitric oxide scavengers, antimicrobial agents, and antimalarials. The aim of this study is to evaluate the immunomodulatory activity of cis-(dichloro)tetraammineruthenium(III) chloride (cis-[RuCl(2)(NH(3))(4)]Cl) on human peripheral blood mononuclear cells (PBMC). The cytotoxic studies performed here revealed that the ruthenium(III) complex presents a cytotoxic activity towards normal human PBMC, only at very high concentration. Results also showed that cis-[RuCl(2)(NH(3))(4)]Cl presents a dual role on PBMC stimulating proliferation and interleukin-2 (IL-2) production at low concentration and inducing cytotoxicity, inability to proliferate, and inhibiting IL-2 production at high concentration. The noncytotoxic activity of cis-[RuCl(2)(NH(3))(4)]Cl at low concentration towards PBMC, which correlates with the small number of annexin V positive cells and also the absence of DNA fragmentation, suggest that this compound does not induce apoptosis on PBMC. For the first time, we show that, at low concentration (10-100 microg L(-1)), the cis-[RuCl(2)(NH(3))(4)]Cl compound induces peripheral blood lymphocytes proliferation and also stimulates them to IL-2 production. These results open a new potential applicability of ruthenium(III) complexes as a possible immune regulatory compound acting as immune suppressor at high concentration and as immune stimulator at low concentration.

Abstract
Ruthenium complexes have attracted much attention as possible building blocks for new transition-metal-based antitumor agents. The present study examines the mitotoxic and clastogenic effects induced in the root tips of Allium cepa by cis-tetraammine(oxalato)ruthenium(III) dithionate {cis-[Ru(C(2)O(2))(NH(3))(4)](2)(S(2)O(6))} at different exposure durations and concentrations. Correlation tests were performed to determine the effects of the time of exposure and concentration of ruthenium complex on mitotic index (MI) and mitotic aberration index. A comparison of MI results of cis-[Ru(C(2)O(2))(NH(3))(4)](2)(S(2)O(6)) to those of lead nitrate reveals that the ruthenium complex demonstrates an average mitotic inhibition eightfold higher than lead, with the frequency of cellular abnormalities almost fourfold lower and mitotic aberration threefold lower. A. cepa root cells exposed to a range of ruthenium complex concentrations did not display significant clastogenic effects. Cis-tetraammine(oxalato)ruthenium(III) dithionate therefore exhibits a remarkable capacity to inhibit mitosis, perhaps by inhibiting DNA synthesis or blocking the cell cycle in the G2 phase. Further investigation of the mechanisms of action of this ruthenium complex will be important to define its clinical potential and to contribute to a novel and rational approach to developing a new metal-based drug with antitumor properties complementary to those exhibited by the drugs already in clinical use.

Abstract
The thermodynamics of the binding of the antitumor ammine, amine, and immine complexes of ruthenium(II) and ruthenium(III) to DNA and peptides was studied computationally using model molecules. We performed density functional calculations on several monofunctional ruthenium complexes of the formula [Ru(NH3)5B]z+, where B is an adenine, guanine, or cytosine nucleobase or an 4-methylimidazole, a dimethylthioether, or a dimethylphosphate anion and z = 2 and 3. The pentammineruthenium fragment has been intensively studied and also constitutes a good model for a wide class of antitumor ammine, amine, and imine complexes of Ru(II) and Ru(III), while the considered bases/ligands have been chosen as models for the main binding sites of DNA, nucleobases, and phosphate backbone and proteins, histidyl, and sulfur-containing residue such as methionine or cysteine. Bond dissociation enthalpies and free energies have been calculated for all the considered metal binding sites both in the gas phase and in solution and allow building a binding affinity order for the considered nucleic acid or protein binding sites. The binding of guanine to some bifunctional complexes, [Ru(NH3)(4)Cl2], [cis-RuCl(2)(bpy)2], and [cis-RuCl(2)(azpy)2], has also been considered to evaluate the effect of a second labile chloro or aquo ligand and more realistic polypyridyl and arylazopyridine ligands.

Abstract
Several metallic compounds recognized as potent antitumor agents, have been developed and tested in vivo and in vitro. In this work, we evaluated the toxic, therapeutic, and cytotoxic properties of the cis-dichloro-tetra-amine-ruthenium(III) chloride. Transplanted animals with Sarcoma 180 cells were treated with ruthenium(III) complex and injected i.p., at different time intervals. After the 15th day, tumoral postimplant, the animals were sacrificed and their lungs, kidneys, liver, and tumors were removed and processed for histopathological analysis. Blood samples were also taken for haematological and biochemical analyses. Interaction between the ruthenium complex and the DNA was also investigated. Besides being cytotoxic for the S180 cells, the metallic compound induced tumoral volume reduction and increased survival time of the animals treated. Serum levels of LDH, creatinine, and bilirubin increased, but no serious irreversible histopathological alterations were observed in the analyzed tissues. The compound did not cause anemia, but reduced the number of leukocytes in the treated animals. The absence of viable S180 cells, necrotic cells, and the presence of granulation tissue were observed in tumor tissue of treated animals. The Ru(III) complex, in the presence of the reduction agent, caused plasmid DNA to fragment. These results suggest that cis-RuCl(2)(NH(3))(4)Cl compound is a potent antitumoral drug in vitro and in vivo, which seems to involve binding to DNA molecule.

Abstract
The Ru(III) complex salt KP1019 induced formation of H2O2 in colorectal tumor cells in a dose-dependent way. It also caused DNA-strand breaks if only weakly doubling tail length to 55.87+/-3.97 microm. Both effects were prevented by 5mM N-acetylcysteine (NAC) which also reduced cytotoxicity (IC(50) 55 vs 30 microM without NAC). Induction of apoptosis was shown by loss of mitochondrial membrane potential in 63.4+/-2.1% of the population and by caspase-dependent cleavage of poly-(ADP-ribose)-polymerase (PARP). Both effects were inhibited by NAC which reduced the population with depolarized mitochondrial membranes to 24.1+/-1.2% and prevented PARP-cleavage indicating a central role oxidative stress in KP1019-induced apoptosis.

Abstract
Since transferrin was discovered more than half a century ago, a considerable effort has been made towards understanding tranferrin-mediated iron uptake. However, it was not until recently with the identification and characterization of several new genes related to iron homeostasis, such as the hemochromatosis protein HFE and the iron transporter DMT1, that our knowledge has been advanced dramatically. A major pathway for cellular iron uptake is through internalization of the complex of iron-bound transferrin and the transferrin receptor, which is negatively modulated by HFE, a protein related to hereditary hemochromatosis. Iron is released from transferrin as the result of the acidic pH in endosome and then is transported to the cytosol by DMT1. The iron is then utilized as a cofactor by heme and ribonucleotide reductase or stored in ferritin. Apart from iron, many other metal ions of therapeutic and diagnostic interests can also bind to transferrin at the iron sites and their transferrin complexes can be recognized by many cells. Therefore, transferrin has been thought as a "delivery system" for many beneficial and harmful metal ions into the cells. Transferrin has also be widely applied as a targeting ligand in the active targeting of anticancer agents, proteins, and genes to primary proliferating malignant cells that overexpress transferrin receptors. This is achieved by conjugation of transferrin with drugs, proteins, hybride systems with marcomolecules and as liposomal-coated systems. Conjugates of anticancer drugs with transferrin can significantly improve the selectivity and toxicity and overcome drug resistance, thereby leading to a better treatment. The coupling of DNA to transferrin via a polycation such as polylysine or via cationic liposomes can target and transfer of the extrogenous DNA particularly into proliferating cells through receptor-mediated endocytosis. These kinds of non-viral vectors are potential alternatives to viral vectors for gene therapy, if the transfection efficiency can be improved. Moreover, transferrin receptors have shown potentials in delivery of therapeutic drugs or genes into the brain across blood-brain barrier.
