Abstract
The interactions of 8-hydroxybenzo[b]quinolizinium and 9-hydroxybenzo[b]quinolizinium with DNA are investigated in detail. Specifically, spectrophotometric and spectrofluorimetric titrations, thermal DNA-denaturation experiments as well as CD- and LD-spectroscopic analysis show that a pH shift by just one or two orders of magnitude has a significant impact on the interactions of the acidic ligands with the nucleic acid. Both ligands bind with high affinity to DNA at pH 6 (Kb ≈105 m-1 ). At pH 7 or 8, however, the binding interactions are much weaker because of the formation of the corresponding charge-neutral conjugate bases, the affinity to DNA of which is reduced because of the resulting lack of a positive charge. Notably, the variation of DNA affinity occurs in a range that corresponds to the fluctuations of pH values under physiological conditions, so that these ligands may be employed to target DNA in tissue with particular pH values, especially, cancer cells. The antiproliferative activity of the title compounds under different conditions is also investigated. In the absence of irradiation, both compounds show only a modest cytotoxicity toward cancer cells. However, upon irradiation, even at low UV-A doses, a significant reduction of cell viability of tumor cell lines is induced by the ligands.

Abstract
The alkynyl gold(I) derivative [Au(C≡CPh)(PTA)] (PTA=1,3,5-triaza-7-phosphaadamantane) induces apoptosis in colorectal carcinoma tumour cells (Caco-2) without affecting to normal enterocytes. [Au(C≡CPh)(PTA)] is a slight lipophilic drug, stable in PBS (Phosphate Buffered Saline) and able to bind BSA (Bovin Serum Albumin) by hydrophobic interactions. Once inside the cell, [Au(C≡CPh)(PTA)] targets seleno proteins such as Thioredoxin Reductase 1, increasing ROS (Reactive Oxygen Species) levels, reducing cell viability and proliferation and inducing mitochondrial apoptotic pathway, pro-apoptotic and anti-apoptotic protein imbalance, loss of mitochondrial membrane potential, cytochrome c release and activation of caspases 9 and 3. Moreover, unlike other metal-based drugs such as cisplatin, [Au(C≡CPh)(PTA)] does not target nucleic acid, reducing the risk of side mutation in the DNA. In consequence, our results predict a promising future for [Au(C≡CPh)(PTA)] as a chemotherapeutic agent for colorectal carcinoma.

Abstract
Double and triple lanthanide ion (Ln(3+))-doped synthetic double crossover (DX) DNA lattices and natural salmon DNA (SDNA) thin films are fabricated by the substrate assisted growth and drop-casting methods on given substrates. We employed three combinations of double Ln(3+)-dopant pairs (Tb(3+)-Tm(3+), Tb(3+)-Eu(3+), and Tm(3+)-Eu(3+)) and a triple Ln(3+)-dopant pair (Tb(3+)-Tm(3+)-Eu(3+)) with different types of Ln(3+), (i.e., Tb(3+) chosen for green emission, Tm(3+) for blue, and Eu(3+) for red), as well as various concentrations of Ln(3+) for enhancement of specific functionalities. We estimate the optimum concentration of Ln(3+) ([Ln(3+)]O) wherein the phase transition of Ln(3+)-doped DX DNA lattices occurs from crystalline to amorphous. The phase change of DX DNA lattices at [Ln(3+)]O and a phase diagram controlled by combinations of [Ln(3+)] were verified by atomic force microscope measurement. We also developed a theoretical method to obtain a phase diagram by identifying a simple relationship between [Ln(3+)] and [Ln(3+)]O that in practice was found to be in agreement with experimental results. Finally, we address significance of physical characteristics-current for evaluating [Ln(3+)]O, absorption for understanding the modes of Ln(3+) binding, and photoluminescence for studying energy transfer mechanisms-of double and triple Ln(3+)-doped SDNA thin films. Current and photoluminescence in the visible region increased as the varying [Ln(3+)] increased up to a certain [Ln(3+)]O, then decreased with further increases in [Ln(3+)]. In contrast, the absorbance peak intensity at 260 nm showed the opposite trend, as compared with current and photoluminescence behaviors as a function of varying [Ln(3+)]. A DNA thin film with varying combinations of [Ln(3+)] might provide immense potential for the development of efficient devices or sensors with increasingly complex functionality.

Abstract
Stable RNA triplexes play key roles in many biological processes, while triplexes are thermodynamically less stable than the corresponding duplexes due to the Hoogsteen base pairing. To understand the factors affecting the stabilization of RNA triplexes by octahedral ruthenium(II) complexes, the binding of [Ru(bpy)2(ppn)](2+) (1, bpy=2,2'-bipyridine, ppn=2,4-diaminopyrimido[5,6-b]dipyrido[2,3-f:2',3'-h]quinoxaline) and [Ru(phen)2(ppn)](2+) (2, phen=1,10-phenanthroline) to poly(U)·poly(A)*poly(U) (· denotes the Watson-Crick base pairing and * denotes the Hoogsteen base pairing) has been investigated. The main results obtained here suggest that complexes 1 and 2 can serve as molecular "light switches" and stabilizers for poly(U)·poly(A)*poly(U), while the effectiveness of complex 2 are more marked, suggesting that the hydrophobicity of ancillary ligands has a significant effect on the two Ru(II) complexes binding to poly(U)·poly(A)*poly(U). This study further advances our knowledge on the binding of RNA triplexes with metal complexes, particularly with octahedral ruthenium polypyridyl complexes.

Abstract
A new Rh2(II,II) complex containing one dppn (benzo[i]dipyrido[3,2-a:2,3-c]phenazine) ligand with an extended π-system, cis-H,H-[Rh2(OCCH3NH)2(dppn)(CH3CN)2]2+ (2), was synthesized and characterized. The dppn ligand, which serves as a DNA base pair intercalator, chelates to a single Rh center and is positioned trans to the amidato N atoms of the bridging acetamide ligand. This ligand also possesses a low-lying dppn-centered 3ππ* state that is advantageous for the sensitization of singlet oxygen (1O2), which complex 2 produced with a quantum yield, Φ 1O2460, of 0.22(7) with 460 nm excitation. In addition, one equivalent of CH3CN is released from 2 upon irradiation with visible light, generating cis-H,H-[Rh2(OCCH3NH)2(dppn)(H2O)(CH3CN)]2+ in aqueous media with photoinduced ligand exchange quantum yield, ΦLE450, of 0.0033(1). Thermal denaturation and relative viscosity studies are consistent with a π-stacking interaction of 2 with double-stranded DNA together with covalent binding to the duplex upon irradiation with visible light. Therefore, 2 exhibits dual photoreactivity towards DNA, making it potentially useful for photochemotherapy with enhanced activity relative to compounds able to achieve only one mode of cell death upon irradiation.
