Abstract
With the development of metal-based drugs, Ru(II) compounds present potential applications of PDT (photodynamic therapy) and anticancer reagents. We herein synthesized two naphthyl-appended ruthenium complexes by the combination of the ligand with naphthyl and bipyridyl. The DNA affinities, photocleavage abilities, and photocytotoxicity were studied by various spectral methods, viscosity measurement, theoretical computation method, gel electrophoresis, and MTT method. Two complexes exhibited strong interaction with calf thymus DNA by intercalation. Production of singlet oxygen (1O2) led to obvious DNA photocleavage activities of two complexes under 365 nm light. Furthermore, two complexes displayed obvious photocytotoxicity and low dark cytotoxicity towards Hela, A549, and A375 cells.

Abstract
The photophysical and biological properties of two new phenanthroline-based ligand ruthenium complexes were investigated in detail. Their DNA interaction modes were determined to be the intercalation mode using spectra titration and viscosity measurements. Under irradiation, obvious photo-reduced DNA cleavages were observed in the two complexes via singlet oxygen generation. Furthermore, complex 2 showed higher DNA affinity, photocleavage activity, and singlet oxygen quantum yields than complex 1. The two complexes showed no toxicity towards tumor cells (HeLa, A549, and A375) in the dark. However, obvious photocytotoxicities were observed in the two complexes. Complex 2 exhibited large PIs (phototherapeutic indices) (ca. 400) towards HeLa cells. The study suggests that these complexes may act as DNA intercalators, DNA photocleavers, and photocytotoxic agents.

Abstract
Triazolopyridopyrimidines 3-phenyl-6,8-di(2-pyridyl)-[1,2,3]triazolo[5',1':6,1]pyrido[2,3-d]pyrimidine (1a), 6,8-di(pyridin-2-yl)-[1,2,3]triazolo[1',5':1,6]pyrido[2,3-d]pyrimidine (1b) and 3-methyl-6,8-di(2-pyridyl)-[1,2,3]triazolo[5',1':6,1]pyrido[2,3-d]pyrimidine (1c) were prepared and their electrochemical and luminescence properties were studied in depth. The DNA binding ability of this series of compounds has been investigated by means of UV-vis absorption and fluorescence titrations, steady-state emission quenching with ferrocyanide as well as viscosity measurements. Results have shown that triazolopyridopyrimidine 1a interacts strongly at DNA grooves. This compound also displays preferential binding to GC-rich sequences and the ability to photooxidize guanine. Moreover, these studies have revealed the key role of the phenyl substituent at the triazole ring in the binding affinity of 1a-c. Compounds 1b and 1c did not show appreciable propensity for DNA binding, however these triazolopyridopyrimidines demonstrated to present photoinduced DNA cleavage activity, 1b being more active than 1c. DNA photocleavage mediated by these compounds takes place mainly through single strand scission events and, in a minor extent, through double strand cuts. Mechanistic investigations using radical scavengers showed that both 1b and 1c generate reactive oxygen species (singlet oxygen, superoxide and hydroxyl radicals) upon irradiation. Both type I and type II mechanisms are involved in the photocleavage process. Furthermore, compounds 1a-c were tested for their antiprotozoal activity against four different Leishmania spp. (L. infantum, L. braziliensis, L. guyanensis and L. amazonensis). Triazolopyridopyrimidines 1a and 1c resulted to be more active and selective than the reference drug (miltefosine) in vitro against L. infantum amastigotes. Compound 1a exhibited high leishmanicidal activity against L. infantum spleen forms in the in vivo test.

Abstract
Two new ruthenium complexes with [Ru(L)(2)(qip)](2+) (L=bpy (2,2'- bipyridine), phen (1,10-phenanthroline); qip=2-(2-quinolinyl)imidazo[4,5-f][1,10]phenanthroline), have been synthesized and characterized by elemental analysis, ES-MS, (1)H NMR. The binding properties of two complexes towards CT-DNA were investigated by various optical methods and viscosity measurements. The experiment results suggested that both Ru(II) complexes can intercalate into DNA base pairs. Strong quenching in emission intensity of two Ru(II) complexes were observed upon addition of Ag(+) in the absence and presence of CT-DNA. Furthermore, the two complexes can promote cleavage of pBR322 DNA under irradiation at 365 nm, and complex 2 exhibits a stronger DNA-photocleavage efficiency than complex 1. The mechanism of DNA cleavage suggests that singlet oxygen ((1)O(2)) is likely to be the cleaving agent.
