Abstract
Zinc(II)-complexes with the general formula [Zn(L)2] containing 8-hydroxyquinoline Schiff bases functionalized with 1-(3-aminopropyl)imidazole or 1-(3-aminopropyl)-2-methyl-1H-imidazole on 2-position and their respective ligands (HL1 or HL2) were synthesized and characterized by NMR, UV-Vis, FTIR and CD spectroscopies as well as ESI-MS spectrometry. Single crystals of HL2 and [Zn(L1)2]n were analysed by SC-XRD. [Zn(L1)2]n shows a 1D polymeric chain structure of alternating Zn(II) cations and bridging Schiff base ligands, in contrast to previously reported monomeric structures of analogous complexes. DFT calculations were performed to rationalize the polymeric X-ray structure of Zn(L1)2. Results showed that the ligands can bind as bi- or tridentate to Zn(II) and there is the possibility of a dynamic behavior for the complexes in solution. Both ligands and complexes present limited stability in aqueous media, however, in the presence of bovine serum albumin the complexes are stable. Molecular docking simulations and circular dichroism spectroscopic studies suggest binding to this protein in close proximity to the Trp213 residue. Biological studies on a panel of cancer cells revealed that the Zn(II)-complexes have a lower impact on cell viability than cisplatin, except for triple-negative breast cancer cells in which they were comparable. Notwithstanding, they display much higher selectivity towards cancer cells vs. normal cells, than cisplatin. They induce the generation of ROS and DNA double-strand breaks, primarily through apoptosis as the mode of cell death. Overall, the novel Zn(II)-complexes demonstrate improved induction of apoptosis and higher selectivity, particularly for melanoma cells, compared to previously reported analogues, making them promising candidates for clinical application.

Abstract
We report the synthesis and characterization of three novel Schiff bases (L1-L3) derived from the condensation of 2-carbaldehyde-8-hydroxyquinoline with amines containing morpholine or piperidine moieties. These were reacted with CuCl2 and ZnCl2 yielding six new coordination compounds, with the general formula ML2, where M = Cu(II) or Zn(II) and L = L1-L3, which were all characterized by analytical, spectroscopic (Fourier transform infrared (FTIR), UV-visible absorption, nuclear magnetic resonance (NMR), or electron paramagnetic resonance (EPR)), and mass spectrometric techniques, as well as by single-crystal X-ray diffraction. In the solid state, two Cu(II) complexes, with L1 and L2, are obtained as dinuclear compounds, with relatively short Cu-Cu distances (3.146 and 3.171 Å for Cu2(L1)4 and Cu2(L2)4, respectively). The free ligands show moderate lipophilicity, while their complexes are more lipophilic. The pKa values of L1-L3 and formation constants of the complex (for ML and ML2) species were determined by spectrophotometric titrations, with the Cu(II) complexes showing higher stability than the Zn(II) complexes. EPR indicated the presence of several species in solution as pH varied and binding modes were proposed. The binding of the complexes to bovine serum albumin (BSA) was evaluated by fluorescence and circular dichroism (CD) spectroscopies. All complexes bind BSA, and as demonstrated by CD, the process takes several hours to reach equilibrium. The antiproliferative activity was evaluated in malignant melanoma cells (A375) and in noncancerous keratinocytes (HaCaT). All complexes display significant cytotoxicity (IC50 < 10 μM) but modest selectivity. The complexes show higher activity than the free ligands, the Cu(II) complexes being more active than the Zn(II) complexes, and approximately twice more cytotoxic than cisplatin. A Guava ViaCount assay corroborated the antiproliferative activity.

Abstract
8-Hydroxyquinoline and its derivatives, which belong to a well-known class of quinoline based drugs with varied biological activities, have been extensively explored for the treatments of cancer, Alzheimer's disease, neurodegenerative diseases and other life-threatening diseases. In virtue of the existence of bicyclic heterocyclic scaffold, their bidentate chelators can further bind to metal ions via O- and N-donors from 8-hydroxylquinolinol skeletons to yield a variety of metal 8-hydroxylquinolinol complexes appealing as the anticancer drugs with low toxicity, due to their better biological effects and higher anticancer activities than free 8-hydroxylquinolinol ligands and cis-diammine-dichloro-platinum. The present review summarizes the recent developments in the syntheses, crystal structures, and anticancer activities of metal 8-hydroxylquinolinol complexes, attempting to discover a correlation between their structures and anticancer activities, and to provide an evidence for their potential application perspectives. It means to offer the helpful and meaningful guidance for the researchers in the future syntheses of new and highly efficient anticancer metal 8-hydroxylquinolinol complexes based drugs.

Abstract
Six new copper(II) complexes were prepared: [Cu(ClBrQ)2] (1a, 1b), [Cu(ClBrQ)2]·1/2 diox (2) (diox = 1,4-dioxane), [Cu(BrQ)2] (3), [Cu(dNQ)2] (4), [Cu(dNQ)2(DMF)2] (5) and [Cu(ClNQ)2] (6), where HClBrQ is 5-chloro-7-bromo-8-hydroxyquinoline, HBrQ is 7-bromo-8-hydroxyquinoline, HClNQ is 5-chloro-7-nitro-8-hydroxyquinoline and HdNQ is 5,7-dinitro-8-hydroxyquinoline. Prepared compounds were characterised by infrared spectroscopy, elemental analysis and by X-ray structural analysis. Structural analysis revealed that all complexes are molecular. Square planar coordination of copper atoms in [Cu(XQ)2] (XQ = ClBrQ (1a, 1b), BrQ (3) and ClNQ (6)) and tetragonal bipyramidal coordination in [Cu(dNQ)2(DMF)2] (5) complexes were observed. In these four complexes, bidentate chelate coordination of XQ ligands via oxygen and nitrogen atoms was found. Hydrogen bonds stabilizing the structure were observed in [Cu(dNQ)2(DMF)2] (5) and [Cu(ClNQ)2] (6), no other nonbonding interactions were noticed in all five structures. The stability of the complexes in DMSO and DMSO/water was evaluated by UV-Vis spectroscopy. Cytotoxic activity of the complexes and ligands was tested against MCF-7, MDA-MB-231, HCT116, CaCo2, HeLa, A549 and Jurkat cancer cell lines. The selectivity of the complexes was verified on a noncancerous Cos-7 cell line. Antiproliferative activity of the prepared complexes was very low in comparison with cisplatin, except complex 3; however, its activity was not selective and was similar to the activity of its ligand HBrQ. Antibacterial potential was observed only with ligand HClNQ. Radical scavenging experiments revealed relatively high antioxidant activity of complex 3 against ABTS radical.

Abstract
The three discrete [Zn6] complexes [Na3Zn6(cpdp)3(μ-Bz)3(CH3OH)6][ZnCl4][ZnCl3(H2O)]·3CH3OH·1.5H2O (1), [Na3Zn6(cpdp)3(μ-p-OBz)3(CH3OH)6]·2H2O (2), and [Na3Zn6(cpdp)3(μ-p-NO2Bz)3(CH3OH)6]Cl3·2H2O (3), supported by the carboxylate-based multidentate ligand N,N'-bis[2-carboxybenzomethyl]-N,N'-bis[2-pyridylmethyl]-1,3-diaminopropan-2-ol (H3cpdp), have been successfully synthesized and fully characterized (Bz = benzoate; p-OBz = dianion of p-hydroxybenzoic acid; p-NO2Bz = p-nitrobenzoate). The complexes have been characterized by elemental analysis, FTIR, UV-vis, NMR spectroscopy, PXRD, and thermal analysis, including single-crystal X-ray crystallography of 1 and 2. The molecular architectures of 1-3 are built from the self-assembly of their corresponding [Zn2] units, which are interconnected to the central [Na3(CH3OH)6]3+ core by six endogenous benzoate groups, with each linking one Zn(II) and one Na(I) ion in a μ2:η1:η1-syn-anti bidentate fashion. The composition of the (cpdp3-)3/(Zn2+)6 complexes in 1-3 has been observed to be 1:2, on the basis of the UV-vis titration and NMR spectroscopic results, which is further supported by X-ray crystallography. Systematic biological studies performed with a mice model suggested possible antidiabetic efficacy as well as anticancer activities of the complexes. When complexes 1-3 were administered intraperitoneally in mice, 1 showed a lowering in the blood glucose level, overall maintenance of the pancreatic tissue mass, restriction of DNA damage in pancreatic cells, and retention of lipid droplet (LD) frequency, whereas 2 and 3 showed hepatic tissue mass consistency by inhibiting the DNA damage in hepatic cells, prior to the exposure to a potent diabetic inducer, alloxan (ALX). Similar trends of results were observed in inhibiting the generation of reactive oxygen species (ROS) in the pancreatic and hepatic cells, as examined by spectrofluorometric methods. Thus, 1 seems to be a better compound for overall diabetic management and control, whereas 2 and 3 seem to be promising compounds for designing chemopreventive drugs against hepatic carcinoma.

Abstract
To investigate the effect of different halogen substituents and leaving groups and the flexibility of ligands on the anticancer activity of copper complexes, sixteen copper(ii) complexes with eight different tridentate Schiff-base ligands containing pyridine and 3,5-halogen-substituted phenol moieties were synthesized and characterized by spectroscopic methods. Four of these complexes were also characterized by X-ray crystallography. The cytotoxicity of the complexes was determined in three different tumor cell lines (i.e. the A2780 ovarian, HCT116 colorectal and MCF7 breast cancer cell line) and in a normal primary fibroblast cell line. Complexes were demonstrated to induce a higher loss of cell viability in the ovarian carcinoma cell line (A2780) with respect to the other two tumor cell lines, and therefore the biological mechanisms underlying this loss of viability were further investigated. Complexes with ligand L1 (containing a 2-pycolylamine-type motif) were more cytotoxic than complexes with L2 (containing a 2-(2-pyridyl)ethylamine-type motif). The loss of cell viability in A2780 tumor cells was observed in the order Cu(Cl2-L1)NO3 > Cu(Cl2-L1)Cl > Cu(Br2-L1)Cl > Cu(BrCl-L1)Cl. All complexes were able to induce reactive oxygen species (ROS) that could be related to the loss of cell viability. Complexes Cu(BrCl-L1)Cl and Cu(Cl2-L1)NO3 were able to promote A2780 cell apoptosis and autophagy and for complex Cu(BrCl-L1)Cl the increase in apoptosis was due to the intrinsic pathway. Cu(Cl2-L1)Cl and Cu(Br2-L1)Cl complexes lead to cellular detachment allowing to correlate with the results of loss of cell viability. Despite the ability of the Cu(BrCl-L1)Cl complex to induce programmed cell death in A2780 cells, its therapeutic window turned out to be low making the Cu(Cl2-L1)NO3 complex the most promising candidate for additional biological applications.

Abstract
Aim: We investigated the antitumor effects of zinc(II) complex with S-propyl thiosalicylic acid [Zn(S-pr-thiosal)2] in 4T1 murine breast cancer model. Results: The Zn(S-pr-thiosal)2 complex reduced primary tumor growth in vivo and induced tumor cell apoptosis. The Zn(S-pr-thiosal)2 complex disrupted the balance between pro- and antiapoptotic Bcl-2 family members in 4T1 cells and induced G1/S cell cycle arrest. The Zn(S-pr-thiosal)2 complex increased the percentage of p16, p21 and p27 positive 4T1 cells. There was a significantly decrease in expression of STAT3 and its targets c-Myc and cyclin D3 in 4T1 cells treated with the Zn(S-pr-thiosal)2 complex thus contributing to G1/S cell cycle arrest and/or apoptosis. Conclusion: Our data suggest that the Zn(S-pr-thiosal)2 complex restricted tumor growth through induction of mitochondrial-driven apoptosis and suppression of cell cycle progression.

Abstract
Photosensitisation of riboflavin (Rf) activates aminophylline (Am) resulting into the formation of a highly pro-oxidant Am-Rf system. We have previously shown its macromolecular damaging response in human peripheral lymphocytes, however, its potential inside a cancer cell is yet to be explored. Since, altered redox status of a cancer cell is a reliable therapeutic window in designing anticancer strategies, therefore, it's imperative to investigate whether the reactive oxygen species (ROS) generated by this system readily triggers apoptosis or it is countered by elevated antioxidant machinery of a cancer cell. Here, we have demonstrated DNA damaging and cytotoxic potential of this system in benzopyrene induced lung carcinoma cells. Using various biochemical assays significant macromolecular damage was observed along with mitochondrial membrane disruption as evaluated by rhodamine 6G membrane permeant. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay showed decreased cell viability, confirming cytotoxic action whereas fluorescence and electron microscopic evaluation confirmed apoptosis. ROS scavengers ameliorated the oxidative damage and inhibited cell death, thus confirming, pivotal role of ROS in causing cell death. It was evidently found out that the lung cancer cells were more sensitive towards the photodynamic action of this system, which can be attributed to the upregulated riboflavin metabolism in cancer cell. Hence, we propose a photodynamic mechanism to kill lung cancer cell that exhibits enhanced sensitivity towards cancer cells.

Abstract
Three novel transition metal complexes, Cu(p-2-bmq)Cl2 (1), Zn(p-2-bmq)Cl2 (2) and [Co(p-2-bmq)Cl2]2 (3) (where p-2-bmq = 2-((1-(pyridin-2-yl)-1H-benzoimidazol-2-yl)methyl) quinolone, have been synthesized. The complexes were detected for their cytotoxicity in vitro against four human esophageal cancer cell lines (SMMC7721, BGC823, HCT116 and HT29) by MTT assay. The results showed that they all have anti-tumor cell proliferation activity. E specially, complex 1 exhibited significant cytotoxicity with IC50 value of 15.89 μM against SMMC7721 cells for 72 h. The morphological changes of nuclei by fluorescence staining methods proved that complex 1 could induce intracellular DNA damage. The flow cytometry analysis revealed that the treatment of SMMC7721 cells with complex 1 induced intracellular ROS increased, mitochondrial potential collapse, G2/M-phase arrest, and even apoptosis. These studies should highly valuable for the development of transition metal-based compounds to the potential anticancer medicinal applications.

Abstract
Three novel Ln(III) complexes, namely, [Pm(dmbpy)(ClQ)2NO3] (1), [Yb(dmbpy)(ClQ)2NO3] (2), and [Lu(dmbpy)(ClQ)2NO3] (3), with mixed 5,7-dichloro-2-methyl-8-quinolinol (H-ClQ) and 4,4'-dimethyl-2,2'-bipyridyl (dmbpy) chelating ligands were first synthesized. The cytotoxic activity of Ln(III) complexes 1-3, H-ClQ, and dmbpy against a panel of human normal and cancer cell lines, namely, human non-small cell lung cancer cells (NCI-H460), human cervical adenocarcinoma cancer cells, human ovarian cancer cells, and human normal hepatocyte cells, were evaluated by using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. The three novel Ln(III) complexes showed a high in vitro antitumor activity toward the NCI-H460 with IC50 of 1.00 ± 0.25 nM for 1, 5.13 ± 0.44 μM for 2, and 11.87 ± 0.79 μM for 3, respectively. In addition, Ln(III) complexes 1 and 2 exerted their in vitro antitumor activity/mechanism mainly via the mitochondrial death pathway and caused a G2/M phase arrest in the following order: 1 > 2. An NCI-H460 tumor xenograft mouse model was used to evaluate the Pm(III) complex 1in vivo antitumor activity. Pm(III) complex 1 showed a high in vivo antitumor activity, and the tumor growth inhibition rate (IR) was 56.0% (p < 0.05). In summary, our study on Pm(III) complex 1 revealed promising results in in vitro and in vivo antitumor activity assays.

Abstract
A new iron(iii) complex with 5,7-dichloro-2-methyl-8-quinolinol (HClMQ) as ligands, i.e., [Fe(ClMQ)2Cl] (1), was synthesized and evaluated for its anticancer activity. Compared to the HClMQ ligand, complex 1 showed a higher cytotoxicity towards a series of tumor cell lines, including Hep-G2, BEL-7404, NCI-H460, A549, and T-24, with IC50 values in the range of 5.04-14.35 μM. Notably, the Hep-G2 cell line was the most sensitive to complex 1. Mechanistic studies indicated that complex 1 is a telomerase inhibitor targeting c-myc G-quadruplex DNA and can trigger cell apoptosis via inducing cell cycle arrest and DNA damage.

Abstract
A rhodium(iii) complex, [Rh(MQ)(DMSO)2Cl2] (1), with 8-hydroxy-2-methylquinoline as the ligand was synthesized and characterized. Complex 1 exhibited cytotoxicity against BEL-7404, Hep-G2, NCI-H460, T-24, and A549 cell lines with IC50 values in the micromolar range (6.52-17.86 μM). Various experiments on the Hep-G2 cells showed that complex 1 caused cell cycle arrest at the S phase, downregulation of cdc25 A, cyclin A, cyclin B and CDK2, and upregulation of p21, p27 and p53. Furthermore, cytotoxicity mechanism studies suggested that complex 1-induced apoptosis was achieved via disruption of the mitochondrial function, which led to a significant loss of the mitochondrial membrane potential, an increase in the cellular levels of reactive oxygen species, cytochrome c, and apaf-1, and a fluctuation of the intracellular Ca2+ concentration. Taken altogether, complex 1 can trigger cancer cell death by inducing apoptosis through a mitochondrial dysfunction pathway.

Abstract
Metal complexes have been the subject of numerous investigations in oncology but, despite the plethora of newly synthesized compounds, their precise mechanisms of action remain generally unknown or, for the best, incompletely determined. The continuous development of efficient and sensitive techniques in analytical chemistry and molecular biology gives scientists new tools to gather information on how metal complexes can be effective toward cancer. This review focuses on recent findings about the anticancer mechanism of action of metal complexes and how the ligands can be used to tune their pharmacological and physicochemical properties.

Abstract
The diverse anticancer utility of cisplatin has stimulated significant interest in the development of additional platinum-based therapies, resulting in several analogues receiving clinical approval worldwide. However, due to structural and mechanistic similarities, the effectiveness of platinum-based therapies is countered by severe side-effects, narrow spectrum of activity and the development of resistance. Nonetheless, metal complexes offer unique characteristics and exceptional versatility, with the ability to alter their pharmacology through facile modifications of geometry and coordination number. This has prompted the search for metal-based complexes with distinctly different structural motifs and non-covalent modes of binding with a primary aim of circumventing current clinical limitations. This review discusses recent advances in platinum and other transition metal-based complexes with mechanisms of action involving intercalation. This mode of DNA binding is distinct from cisplatin and its derivatives. The metals focused on in this review include Pt, Ru and Cu along with examples of Au, Ni, Zn and Fe complexes; these complexes are capable of DNA intercalation and are highly biologically active.
