Regression of lung cancer by hypoxia-sensitizing ruthenium polypyridyl complexes.
The ruthenium (II) polypyridyl complexes (RPC), Δ-[(phen)2Ru(tatpp)]Cl2 (Δ-[3]Cl2) and ΔΔ-[(phen)2Ru(tatpp)Ru(phen)2]Cl4 (ΔΔ-[4]Cl4, are a new generation of metal-based antitumor agents. These RPCs bind DNA via intercalation of the tatpp ligand, which itself is redox-active and is easily reduced at biologically relevant potentials. We have previously shown that RPC 4(4+) cleaves DNA when reduce...
متن کاملElectrocatalytic reduction of CO2 to CO by polypyridyl ruthenium complexes.
Electrocatalytic reduction of CO(2) by [Ru(tpy)(bpy)(solvent)](2+) (tpy = 2,2':6',2''-terpyridine, bpy = 2,2'-bipyridine) and its structural analogs is initiated by sequential 1e(-) reductions at the tpy and bpy ligands followed by rate limiting CO(2) addition to give a metallocarboxylate intermediate. It undergoes further reduction and loss of CO.
متن کاملCarbon dioxide reduction by mononuclear ruthenium polypyridyl complexes.
New mononuclear ruthenium complexes with general formula [Ru(bid)(B)(Cl)] (bid is (1Z,3Z)-1,3-bis(pyridin-2-ylmethylene)isoindolin-2-ide; B = bidentate ligand 2,2'-bipyridine or R(2)-bpy, where R = COOEt or OMe) were synthesized and tested as precatalysts for the hydrogenative reduction of CO(2) in 2,2,2-trifluoroethanol (TFE) as solvent with added NEt(3). Significant amounts of formic acid wer...
متن کاملPhotoinduced ligand isomerisation in a pyrazine-containing ruthenium polypyridyl complex.
Photochemically-induced ligand rearrangements for the N2 and N4 coordination isomers of the complex [Ru(bpy)(2)(Hpztr)](2+) and its deprotonated analogue [Ru(bpy)(2)(pztr)](+), where bpy is 2,2'-bipyridyl and Hpztr is pyrazine-1,2,4-triazole ligand, are reported. (1)H NMR spectroscopic and HPLC studies indicate that in acetone and acetonitrile the complexes are photostable when the triazole rin...
متن کاملModulation of internuclear communication in multinuclear Ruthenium(II) polypyridyl complexes
The synthesis and characterization of dinuclear ruthenium polypyridyl complexes based on the bridging ligands 1,3-bis-(5’-(pyridin-2’’-yl)-1’H-1’,2’,4’-triaz-3’-yl)-benzene, 1,4-bis-(5’-(pyridin-2’’-yl)-1’H-1’,2’,4’-triaz-3’-yl)-benzene, 2,5-bis-(5’-(pyridin-2’’yl)-1’H-1’,2’,4’-triaz-3’-yl)-thiophene, 2,5-bis-(5’-(pyrazin-2’’-yl)-1’H-1’,2’,4’-triaz3’-yl)-thiophene, and of their mononuclear anal...
