Abstract
In this article, four new Ru(II) complexes [Ru(dmbpy)2(TFBIP)](PF6)2 (dmbpy = 4,4'-dimethyl-2,2'-bipyridine, TFPIP = 2-(4'-trifluoromethyl)-[1,1'-biphenyl]-4-yl)-1H-imidazo[4,5-f][1,10]phenanthroline) (Ru1), [Ru(bpy)2(TFBIP)](PF6)2 (bpy = 2,2'-bipyridine) (Ru2), [Ru(phen)2(TFBIP)](PF6)2 (phen = 1,10-phenanthroline) (Ru3) and [Ru(dmp)2(TFBIP)](PF6)2 (dmp = 2,9-dimethyl-1,10-phenanthroline) (Ru4) were synthesized and characterized by elemental analysis, HRMS, IR, 1H NMR, 13C NMR and 19F NMR. The in vitro anticancer effect of the complexes on HepG2, A549, B16, HeLa, BEL-7402 and non-cancer LO2 cells was screened using 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) method. The results illustrate that the complexes display moderate anticancer activity. Apoptotic assay with Annexin V/PI double staining method indicated that complexes induce apoptosis in HepG2 cells. Also, the complexes interfere with the mitochondrial functions, accompanied by the production of intracellular ROS as well as a reduction of mitochondrial membrane potential. The results obtained from the western blot demonstrated that the complexes upregulate pro-apoptotic Bax and downregulate anti-apoptotic Bcl-2, which further activates caspase 3 and promotes the cleavage of PARP. RNA-sequence showed that the complexes upregulate the expression of 40 genes and downregulate 66 genes. Antitumour in vivo demonstrated that Ru1 inhibits the tumor growth with a high inhibitory rate of 51.19%. Taken together, these results revealed that complexes Ru1, Ru2, Ru3 and Ru4 induce cell death in HepG2 cells via autophagy and a ROS-mediated mitochondrial apoptotic pathway.

Abstract
Over the past few decades, the landscape of inorganic medicinal chemistry has been dominated by investigations on platinum or ruthenium, while the research based on other metal centers such as rhodium has been relatively insufficient. In this work, a series of cyclometalated rhodium(iii) complexes with imidazo[4,5-f][1,10]phenanthroline containing different aromatic rings were synthesized and characterized. Notably, all the complexes displayed stronger anticancer activity against various cancer cells compared with cisplatin. A mechanism study revealed that the rhodium complexes accumulated in the mitochondria, elevated the levels of mitochondrial reactive oxygen species (ROS) and released cytochrome c, indicating severe mitochondrial damage during the anticancer activity. Further studies illustrated that the rhodium complexes caused cell cycle arrest at the G2/M phase, upregulated the expression of p53 and reduced the ratio of B-cell lymphoma-2 (Bcl-2)/Bcl-2-associated x (Bax), which ultimately resulted in cellular apoptosis. Overall, through mitochondrial pathways, these Rh(iii) complexes could induce cellular apoptosis to a larger extent than cisplatin and should be paid close attention as promising chemotherapeutic drugs in anticancer research.

Abstract
A number of reduced amino Schiff base ligands and corresponding ruthenium(III) complexes were designed and prepared based on the fact that amino acids not only possess multiple coordinate atoms but also improve the solubility of drugs in the body. The interaction of the complexes with calf thymus DNA was analyzed with spectroscopic methods of ultraviolet-visible absorption spectra, DNA competitive binding with ethidium bromide, circular dichroism spectra, and DNA melting experiments, and DNA viscosity measurements, indicating that the complexes bind to DNA primarily in the grooving mode. With respect to the ligands, the cytotoxicity in vitro of the complexes against Hela, A549, and MCF-7 cells was much enhanced, with most of the IC50 values less than 50 μM or even comparable with those of cisplatin.

Abstract
The octahedral Ru(II) complexes containing the 2(2,6-dimethoxypyridine-3-yl)-1H-imidazo(4,5-f)[1, 10]phenanthroline ligand of type [Ru(N-N)2(L)]2+, where N-N = phen (1,10-phenanthroline) (1), bpy (2,2'-bipyridine) (2), and dmb (4,4'-dimethyl-2,2'-bipyridine) (3); L(dmpip) = (2(2,6-dimethoxypyridine-3-yl)1Himidazo(4,5-f)[1, 10]phenanthroline), have been synthesized and characterized by UV-visible absorption, molar conductivity, elemental analysis, mass, IR, and NMR spectroscopic techniques. The physicochemical properties of the Ru(II) complexes were determined by UV-Vis absorption spectroscopy. The DNA binding studies have been explored by UV-visible absorption, fluorescence titrations, and viscosity measurements. The supercoiled pBR322 DNA cleavage efficiency of Ru(II) complexes 1-3 was investigated. The antimicrobial activity of Ru(II) complexes was done against Gram-positive and Gram-negative microorganisms. The in vitro anticancer activities of all the complexes were investigated by cell viability assay, apoptosis, cellular uptake, mitochondrial membrane potential detection, and semi-quantitative PCR on HeLa cells. The result indicates that the synthesized Ru(II) complexes probably interact with DNA through an intercalation mode of binding with complex 1 having slightly stronger DNA binding affinity and anticancer activity than 2 and 3.

Abstract
Ruthenium(ii) [Ru(ii)] polypyridyl complexes have been the focus of intense investigations since work began exploring their supramolecular interactions with DNA. In recent years, there have been considerable efforts to translate this solution-based research into a biological environment with the intention of developing new classes of probes, luminescent imaging agents, therapeutics and theranostics. In only 10 years the field has expanded with diverse applications for these complexes as imaging agents and promising candidates for therapeutics. In light of these efforts this review exclusively focuses on the developments of these complexes in biological systems, both in cells and in vivo, and hopes to communicate to readers the diversity of applications within which these complexes have found use, as well as new insights gained along the way and challenges that researchers in this field still face.

Abstract
This review describes the analytical techniques used to detect DNA-probes such as Ru(II) complexes with hetero cyclic imidazo phenanthroline (IP) ligands. Studies on drug-DNA interactions are useful biochemical techniques for visualization of DNA both in vitro and in vivo. The interactions of small molecules that binds to DNA are mainly classified into two major classes, one involving covalent binding and another non-covalent binding. Covalent binding in DNA can be irreversible and may leads to inhibition of all DNA processes which subsequently leads to cell death. Usually, covalent interactions leads to permanent changes in the structure of nucleic acids. The non-covalent interaction of molecules with DNA can be due to electrostatic interaction, intercalation and groove binding. These interactions of DNA probes can be explored by various spectroscopic techniques viz. UV-visible, emission, emission quenching spectroscopy, viscosity and thermal denaturation measurements.

Abstract
Four new ruthenium(II) polypyridyl complexes [Ru(N-N)2(bddp)](ClO4)21-4 (N-N=dmb: 4,4'-dimethyl-2,2'-bipyridine 1, bpy: 2,2'-bipyridine 2, phen: 1,10-phenanthroline 3 and dmp: 2,9-dimethyl-1,10-phenanthroline 4, bddp=benzilo[2,3-b]-1,4-diazabenzo[i]dipyrido[3,2-a:2',3'-c]phenazine) were synthesized and characterized by elemental analysis, ESI-MS and (1)H NMR. The cytotoxicity in vitro of the complexes against BEL-7402, HeLa, MG-63 and A549 cell lines was investigated by MTT method. The complexes show high cytotoxic activity toward the selected cell lines with an IC50 value ranging from 5.3±0.6 to 15.7±3.6μM. The apoptosis was studied with acridine orange (AO)/ethdium bromide (EB) and Hoechst 33258 staining methods. The cellular uptake was investigated with DAPI staining method. The reactive oxygen species (ROS) and mitochondrial membrane potential were performed under fluorescent microscope and flow cytometry. The complexes can induce an increase in the ROS levels and a decrease in the mitochondrial membrane potential. The comet assay was studied with fluorescent microscope. The percentage in apoptotic and necrotic cells and cell cycle arrest were assayed by flow cytometry. The effects of the complexes on the expression of caspases and Bcl-2 family proteins were studied by western blot analysis. The results show that the complexes induce apoptosis in A549 cells through an ROS-mediated mitochondrial dysfunction pathway, which was accompanied by regulating the expression of Bcl-2 family proteins.

Abstract
Two new mono-nuclear heteroleptic platinum(II) complexes, [Pt(bpy)(iip)](PF6)2 (1) and [Pt(bpy)(miip)](PF6)2·2H2O (2) (bpy is 2,2'-bipyridine; iip is 2-(imidazo-4-yl)-1H-imidazo[4,5-f] [1,10] phenanthroline; miip is 2-(1-methylimidazo-2-yl)-1H-imidazo[4,5-f] [1, 10] phenanthroline), have been synthesized and fully characterized by CHN analysis, electrospray ionization and MALDI-TOF mass spectrometry, (1)H NMR, FT-IR (ATR), and UV-Vis spectrophotometer. Cytotoxicity, ability to inhibit DNA transcription and DNAse activity of the complexes were studied. The DNA-binding behaviors of both complexes have also been studied by spectroscopic methods, cyclic voltammetry and viscosity measurements. Both complexes showed cytotoxic properties and 2 was more cytotoxic than 1. DNA transcription was inhibited upon increasing concentrations of both complexes. The complex 2 was found to be a better inhibitor than 1. The same pattern can be seen in the DNAse profile of the complexes. In addition, 2 was found to promote cleavage of pBR322 DNA at a lower concentration than 1. The spectroscopic, electrochemical and viscometric results indicate that both complexes show some degree of binding to DNA in an intercalative mode, resulting in intrinsic binding constants K b = 3.55 ± 0.6 × 10(4) M(-1) and 7.01 ± 0.9 × 10(4) M(-1) for 1 and 2, respectively. The difference in the DNA-binding affinities of 1 and 2 may presumably be explained by the methylated imidazole nitrogen atom that makes the compound more hydrophobic and gives better intercalative binding ability to DNA's hydrophobic environment.

Abstract
Three new ruthenium(II) polypyridyl complexes [Ru(phen)2BrIPC](2+) (1), [Ru(bpy)2 BrIPC](2+) (2) and [Ru(dmb)2BrIPC](2+) (3) where, BrIPC = (6-bromo-3-(1H-imidazo[4,5-f] [1,10]-phenanthroline, phen = 1,10-phenanthroline, bpy = 2,2' bipyridine, dmb = 4,4'-dimethyl 2,2' bipyridine, were synthesised and characterised. DNA-binding nature was investigated by spectroscopic titrations and mode of binding was assessed by viscosity measurements. The DNA-binding constants Kb of complexes 1, 2 and 3 were determined to be in the order of 10(5). Experimental results showed that these complexes interact with CT-DNA by intercalative mode. Photocleavage and antimicrobial activities were complex concentration dependent, at high concentration, high activity and vice versa. MTT assay was performed on HeLa cell lines, IC50 values of complexes in the order of 3 > 2 > 1 > cisplatin. From comet assay, cellular uptake studies, we observed that complexes could enter into the cell membrane and accumulate inside the nucleus. Molecular docking studies support the DNA binding affinity with hydrogen bonding and van der Waals attractions between base pairs and phosphate backbone of DNA with metal complexes.
