Two photoactive Ru (II) compounds based on tetrazole ligands for photodynamic therapy

Ru (II) compounds have potential application in photodynamic therapy (PDT). In the current study, two Ru (II) compounds based on the auxiliary ligand 2,2′-bipyridine (bipy) by changing main ligands 5-(2-pyridyl) tetrazole (Hpytz) and di(2H-tetrazol-5-yl) amine (H2datz) have been successfully synthesized and characterized, [Ru (pytz)(bipy)2][PF6] (1) and [Ru(Hdatz)(bipy)2][PF6] (2). These compounds can form nanoparticles (NPs) by nano-precipitation. And [Ru(pytz)(bipy)2][PF6] NPs with a lower half maximal inhibitory concentration (IC50) of 37 μg/mL on HeLa cells than that of [Ru(Hdatz)(bipy)2][PF6] NPs (65 μg/mL). Meanwhile, negligible dark toxicity has been also observed for these NPs even under high concentrations. The results show that [Ru(pytz)(bipy)2][PF6] (1) and [Ru(Hdatz)(bipy)2][PF6] (2) NPs can inhibit cell proliferation in vitro, and may be potential candidates for photodynamic therapy.

An efficient light-driven P450 BM3 biocatalyst

P450s are heme thiolate enzymes that catalyze the regio-and stereoselective functionalization of unactivated C-H bonds using molecular dioxygen and two electrons delivered by the reductase. We have developed hybrid P450 BM3 heme domains containing a covalently attached Ru(II) photosensitizer in order to circumvent the dependency on the reductase and perform P450 reactions upon visible light irradiation. A highly active hybrid enzyme with improved stability and a modified Ru(II) photosensitizer is able to catalyze the light-driven hydroxylation of lauric acid with total turnover numbers of 935 and initial reaction rate of 125 mol product/(mol enzyme/min).

Observation of cascade f → d → f energy transfer in sensitizing near-infrared (NIR) lanthanide complexes containing the Ru(ii) polypyridine metalloligand

Distinguishable d → f or f → d energy transfer processes depending on lanthanide ions are observed in isomorphous d-f heterometallic complexes containing the Ru(ii) metalloligand (LRu), which lead to sensitized NIR emission (for Nd3+ and Yb3+) or enhanced red emission of LRu (for Eu3+ and Tb3+), and represent the first eye-detectable evidence of f → d energy transfer processes in Ln-Ru bimetallic complexes. Based on the systematic luminescence and decay lifetime study, cascade f → d → f energy transfer has been proposed in Ln1-Ru-Ln2 trimetallic systems for improved NIR sensitization.

A new method for the utilization of compounds of the type [Ru(bpy)2(CO)Cl]+ as a starting material for the synthesis of [Ru(N6)]2+ type compounds

[Ru(R-bpy)2Cl2] is an important starting material for the synthesis of [Ru(N6)]2+ complexes. During the conventional synthesis procedure of [Ru(R-bpy)2Cl2], yield loss of up to 50% occurs, due to the formation of the side product [Ru(R-bpy)2(CO)Cl]+. The CO ligand hinders further conversion to [Ru(N6)]2+. Here we describe a simple and efficient removement of the CO ligand followed by a complexation of a third chelating ligand generating [Ru(N6)]2+. Complete removal of the CO ligand and formation of an intermediate state is verified by ESI-MS spectrometry and IR spectroscopy. After complexation of the third chelating ligand bpy, pure [Ru(R-bpy)3]2+ was formed with complete conversion. Purity of [Ru(R-bpy)3]2+ was ensured by IR-, NMR-spectroscopy and MS spectrometry.

Electropolymerisable bipyridine ruthenium(II) complexes: Synthesis, spectroscopic and electrochemical characterisation of 4-((2-thienyl) ethenyl)- and 4,4′-di((2-thienyl) ethenyl)-2,2′ -bipyridine ruthenium complexes

Four new ruthenium polypyridyl complexes with mono- or di-((2-thienyl) ethenyl) substituted bipyridines have been synthesized. The complexes were characterized by NMR, elemental analysis, UV-Vis absorption and electrochemistry (differential pulse and cyclic voltammetry). Electroactive polymer films of these complexes have been prepared by oxidative electropolymerisation and characterized by UV-Vis absorption spectroscopy and electrochemistry. The electrochemically induced polymerisation of the complexes resulted in a significant shift of the oxidation potential of the Ru(II)-Ru(III) process towards more positive potentials. Also, MLCT absorption band of the polymeric complexes is shifted towards shorter wavelengths. These results are interpreted in terms of an interruption of the conjugated system of the (2-thienyl)ethenyl-substituted bipyridine ligands due to a radical polymerisation mechanism affecting rather the ethenyl part of the ligand than the thienyl.

Tuning the properties of ruthenium bipyridine dyes for solar cells by substitution on the ligands - Characterisation of bis[4,4′-di(2-(3- methoxyphenyl)ethenyl)-2,2′ -bipyridine] [4,4′-dicarboxy-2,2′- bipyridine]ruthenium(II) dihexafluorophosphate

The new dye complex bis[4,4′-di(2-(3-methoxyphenyl)ethenyl)-2, 2′-bipyridine][4,4′-dicarboxy-2,2′-bipyridine]-ruthenium(II) dihexafluorophosphate (1) has been prepared, characterised by absorption spectroscopy and adsorbed onto nanocrystalline TiO2 electrodes. The resulting system was studied by absorption spectroscopy, electrochemistry and photoelectrochemistry and the results were compared to those for a reference system with bis[2,2′-bipyridine]-[4,4′-dicarboxy-2,2′- bipyridine]ruthenium(II) (2). The system with 1 displays a broader and red-shifted UV-vis absorption compared to that with 2. Moreover, the system with 1 is less sensitive towards the water content in the electrolyte, and an adsorbed monolayer of 1 remains on the electrode surface after days even in aqueous NaOH (0.1 M), while 2 desorbs immediately.

Formation of Optically Active (bipy = 2,2'-bipyridyl) by Photodissociation of Cl2 in Dichloromethane

An optically active bis-chelated complex, (bipy = 2,2'-bipyridyl), has been obtained when enantiomeric Cl2 was illuminated by visible light in dichloromethane.From the dependence of the optical purity of the product on light intensity, it is proposed that the reaction from Δ-Cl2 to Δ- (chirality retention) proceeds by way of the dissociation of a monodentate ligand, bipy*, from a photoactivated intermediate, Δ-*)Cl>Cl in the dark, while the reaction to Λ- (chirality inversion) involves the further photoactivated configurational change of Δ-*)Cl>Cl to Λ-*)Cl>Cl.Racemization is avoided under the conditions of weak light and high temperature.The synthetic value of optically active as a chiral intermediate has been exemplified by preparing a new chiral amphiphilic ruthenium(II) complex.
