  Cellular Toxicity Induced by the Photorelease of a Caged Bioactive Molecule: Design of a Potential Dual-Action Ru(II) Complex

  摘要：

  The series [Ru(tpy)(CH3CN)(3)](2+) (1), cis-[Ru(tpy)-(CH3CN)(2)C1](+) (2), and [Ru(tpy)(5CNU)(3)](2+) (3), where tpy = 2,2':6',2 ''-terpyridine and SCNU = 5-cyanouracil, was synthesized, and their photochemical properties were investigated for use as potential photodynamic therapy (PDT) agents. When irradiated with visible light, 1-3 exhibit efficient exchange of the axial CH3CN or SCNU ligand with H2O solvent molecules. Complexes 1-3 also exhibit photoinitiated binding to DNA when irradiated with lambda(irr) >= 395 nm light, and DNA binding can be accessed for 2 with lambda(irr) > 645 am, well within the PDT window. Since 3 binds DNA and simultaneously releases biologically active 5CNU, it has the potential to be a dual-action therapeutic agent. Indeed, 3 is cytotoxic upon irradiation with visible light, whereas 1 is not under similar experimental conditions. The lack of toxicity imparted by 1 is explained by the exchange of only one CH3CN ligand in the complex under the irradiation conditions used for the cellular studies. Strategies are being sought to increase the quantum yields of ligand exchange and the cellular penetration of these compounds.

During the charging/discharging cycles, the pH value of the solution gradually changed accompanied by a change of the open-circuit potential (OCP). The changes for the OCP and pH value of the solution in the anodic and cathodic half-cells were in good agreement with the predicted values from the Pourbaix diagrams for the

  The tetradentate ligands, 2,2'-(1H-pyrazole-3,5-diyl)bis(4-methylpyridine) (4,4'-Me(2)dppzH), 2,2'-(1H-pyrazole-3,5-diyl)bis(6-methylpyridine) (6,6'-Me(2)dppzH), 3,5-di(pyrid-2-yl)pyrazole (dppzH), and dipyridyloxadiazole (dpo) react with either Ru(trpy)Cl-3 or trans-Ru(trpy)Cl-2(NCCH3), where trpy is 2,2',2"-terpyridine, to form a variety of Ru(II) complexes. Among these are the symmetrical chloro-bridged Ru(II) dimer and the "in" and "out" geometric isomers of the monometallic Ru(II) containing species where "in" and "out" refer to the orientation of the Ru-Cl vector relative to the centroid of the ligand backbone. Thirteen complexes were prepared and painstakingly purified by. careful recrystallization and/or exhaustive column chromatography. These complexes were characterized by H-1 and C-13 NMR, electronic absorption, and infrared spectroscopy. Additionally, [Ru-2(trpy)(2)(6,6'-Me(2)dppz)mu-Cl](BF4)(2) (3b(BF4)(2)), [Ru-2(trpy)(2)(4,4'-Me(2)dppz)mu-Cl](PF6)(2).0.5MeOH (3c), [Ru-2(trpy)(2)(6,6'-Me(2)dppz)(CH2C(O)CH3)](PF6)(2.) 0.5(CH3)(2)CO (9b), "in"-[Ru(trpy)(4,4'-Me(2)dppz)Cl](PF6).(CH3)(2)CO (1c), and "out"-[Ru(trpy)(dpo)Cl](PF6).(CH3)(2)CO (2d) were characterized by X-ray crystallography. Several ligand substitution reactions were attempted. For example, [Ru-2(trpy)(2)(6,6'-Me(2)dppz)mu-Cl](BF4)(2) (3b) was reacted with hydroxide ion to produce [Ru-2(trpy)(2)(6,6'-Me(2)dppz)mu-OH](PF6)(2) (6b). Complex 6b reacts with benzyl bromide to produce [Ru-2(trpy)(2)(6,6'-Me(2)dppz)mu-Br](PF6)(2) (7b) or with (CH3)(3)Sil to produce [Ru-2(trpy)(2)(6,6'-Me(2)dppz)mu-l](PF6)(2) (8b). Reaction of 6b with acetone forms the methyl enolate complex [Ru-2(trpy)2(6,6'-Me(2)dppz)(CH2COCH3)](PF6)(2) (9b) while, analogously to a Cannizarro reaction, the reaction with benzaldehyde forms the bridging benzoate complex [Ru-2(trpy)(2)(6,6'-Me(2)dppz)(C6H4CO2)](PF6)(2) (11b). The bridging azide complex [Ru-2(trpy)(2)(6,6'-Me(2)dppz)mu-N-3](PF6)(2) (10b) is formed by reaction of 6b with (CH3)(3)-SiN3. Additionally, the chloride ligands of the monometallic complexes of "in"-[Ru(trpy)(dpo)Cl](PF6) (1d), "in"-[Ru(trpy)(4,4'-Me(2)dpo)Cl](PF6) (1e), and "out"-[Ru(trpy)(dpo)Cl](PF6) (2d) were substituted with water to form their respective aqua complexes, 4d, 4e, and 5d. All of the complexes exhibit broad unsymmetrical absorption bands in the visible portion of the electromagnetic spectrum. The dimetallic complexes 3b and 3c exhibit two, 1e(-) reversible oxidation waves at +072 and +1.15 V, and at +0.64 and +1.13 V, respectively. These complexes were not emissive.
