A series of arene ruthenium(II) complexes coordinated by phenanthroimidazole derivates, [(C6H6)Ru(L)Cl] Cl·2H2O (1b L = IP, 2b L = p-NMe2PIP, 3b L = p-MeOPIP, 4b L = p-HOPIP, 5b L = p-COOHPIP, 6b L = p-CF3PIP, 7b L = p-BrPIP) have been synthesized in yields of 89-92% under microwave irradiation in 30 min, and the crystal structure of 1b by XRD gives a typical “piano stool” conformation. The antitumor activity of these complexes against various tumor cells have been evaluated by MTT assay, and the results show that this type of arene Ru(II) complexes exhibit acceptable inhibitory effect against all of these tumor cells, especially osteosarcoma MG-63 cells, but with low toxicity toward HK-2 human normal cells. Studies on the mechanism revealed that cell cycle arrest at S-phase in MG-63 cells induced by the arene Ru(II) complex 2b, which was confirmed by the increase in the percentage of cells at S-phase and down-regulator of cyclin A. The further studies by Comet assay at single cell level indicated that DNA damage in MG-63 cells was triggered by 2b, following with the up-regulation of phosphorylated p53 and histone. The studies by spectroscopy in vitro also indicate that 2b bind to DNA molecule by intercalative mode to disturb the bio-function of tumor cells. In conclusion, the synthetic arene Ru(II) complexes could serve as novel p53 activator with potential application in cancer chemotherapy.

A water-soluble metallo-supramolecular polymer MSP-f-6Np, which possesses a regular pore aperture of 1.4 nm, has been assembled from a structurally flexible naphthalene-appended [Ru(bipy)3]2+ complex and cucurbit[8]uril. As the first periodic metallo-supramolecular polymer formed by a flexible building block, MSP-f-6Np exhibits a hydrodynamic diameter of 122 and 164 nm at 0.1 and 2.0 mM of the monomer concentrations. Synchrotron small angle X-ray scattering experiments confirm that MSP-f-6Np possesses porosity periodicity in both the solution and solid states. Compared with a control, the new highly ordered porous system displays enhanced photocatalytic activity for the degradation of organic dyes.

Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 15746-57-3, C20H16Cl2N4Ru. A document type is Article, introducing its new discovery., HPLC of Formula: C20H16Cl2N4Ru

Covalently linked bipyridyl ligands (L-L) with alkyl linkages varying from (-CH2-)2 to (-CH2-)12 were used to prepare ruthenium oxo dimers of the form [(bpy) (H2O)RuO(L-L)Ru(2O) (bpy)]4+. The bridging alkyl linkage increases the stability of these oxo dimers by maintaining the relative proximity of the two ruthenium centers even when the oxo bridge is cleaved. These complexes have been characterized by electronic spectroscopy and electrochemistry. The electrochemistry in CH3CN/0.1M TBAP exhibits a reversible one-electron oxidation followed by a second reversible two-electron oxidation which becomes catalytic in aqueous solution. The catalytic generation of dioxygen from water was observed upon bulk electrolysis of the oxo dimer at +1.39 V.

As hypoxia is an important factor to limit chemotherapeutic efficacy in tumors, we herein report three ruthenium(II)-arene complexes containing a hypoxia inducible factor-1alpha inhibitor (YC-1), which endow the organometallic complexes with potential for hypoxia targeting. In vitro tests showed the resulting complexes had higher anticancer activities in hypoxia than in normoxia against the tested cancer cell lines. Western blot analysis revealed that complexes 1-3 blocked HIF-1alpha protein accumulation under hypoxic conditions. Moreover, these complexes displayed much less cytotoxicity toward the normal human umbilical vein endothelial cell line (HUVEC), indicating that complexes 1-3 may be selectively cytotoxic for human cancer cell lines. These findings proved that ligation with YC-1 endowed these organometallic ruthenium(II) complexes with potential for hypoxia targeting in addition to enhancing their anticancer activities.

The reactivity of [Pt2(mu-S)2 (PPh3)4] towards [RuCl2 (eta6-arene)]2 (arene=C6 H6, C6Me6, p -MeC6 H4Pri = p-cymene), [OsCl2 (eta6- p -cymene)]2 and [MCl2 (eta5-C5Me5)]2 (M=Rh, Ir) have been probed using electrospray ionisation mass spectrometry. In all cases, dicationic products of the type [Pt2(mu-S)2(PPh3)4 ML]2+ (L=pi-hydrocarbon ligand) are observed, and a number of complexes have been prepared on the synthetic scale, isolated as their BPh4- or PF6- salts, and fully characterised. A single-crystal X-ray structure determination on the Ru p-cymene derivative confirms the presence of a pseudo-five-coordinate Ru centre. This resists addition of small donor ligands such as CO and pyridine. The reaction of [Pt2(mu-S)2 (PPh3)4] with RuClCp(PPh3) 2 (Cp=eta5-C5H5) gives [Pt2(mu-S)2(PPh3) 4RuCp]+. In addition, the reaction of [Pt2(mu-S)2(PPh3)4] with the related carbonyl complex [RuCl2(CO)3] 2, monitored by electrospray mass spectrometry, gives [Pt2(mu-S)2(PPh3)4 Ru(CO)3Cl]+.
