In-situ infrared studies performed with operating Ru-complex-sensitized wet solar cells using a total reflection technique reveal that the ruthenium complex (both tri- and mononuclear) attached to TiO2 is photoelectrochemically transformed and irreversibly consumed under conditions of insufficient regeneration by iodide or from the oxide within the nanocrystalline TiO2 pores. The sensitizer [(Ru(bpy)2(CN)2)2Ru(bpca)2] 2- (bpy is 2,2a¿²-bipyridine, bpca is 2,2a¿²-bipyridine-4,4a¿²-dicarboxylate) decomposes into fragments; one of them was identified to be Ru(bpy)2(CN)2. For the sensitizer Ru(bpca)2(SCN)2, it is shown that a molecular fragment (absorbing at 2013 cm-1) is generated which is diffusing out of the nanostructured TiO2 layer. Due to its correlation with the photocurrent density, it is identified as a product of the oxidized sensitizer. Due to a high serial resistance introduced by the total reflection element and the resulting low fillfactor of the sensitization cell during in-situ measurements, only small photocurrents (5-10 I¼A cm-2) could be passed through the sensitizing interface. Since the rate of product formation should be proportional to the ratio of photocurrent density to iodide concentration, the iodide concentration was correspondingly reduced (1-10 mM) as compared to the conditions in a solar cell (10 mA cm-2, 1 M). This spectroscopic technique was developed because efforts to produce stable sensitization solar cells proved to be unsuccessful due to sealing problems. Our experiments do not seem to permit extrapolation to 107-108 electron transfer numbers for sensitizing Ru complexes, and real long-term testing is required for reevaluating long-term performance.

Reaction of the benzene-linked bis(pyrazolyl)methane ligands, 1,4-bis{bis(pyrazolyl)-methyl}benzene (L1) and 1,4-bis{bis(3-methylpyrazolyl)methyl}benzene (L2), with pentamethylcyclopentadienyl rhodium and iridium complexes [(eta5-C5Me5)M(mu-Cl)Cl]2 (M = Rh and Ir) in the presence of NH4PF6 results under stoichiometric control in both, mono and dinuclear complexes, [(eta5-C5Me5)RhCl(L)]+ {L = L1 (1); L2 (2)}, [(eta5-C5Me5)IrCl(L)]+ {L = L1 (3); L2 (4)} and [{(eta5-C5Me5)RhCl}2(mu-L)]2+ {L = L1 (5); L2 (6)}, [{(eta5-C5Me5)IrCl}2(mu-L)]2+ {L = L1 (7); L2 (8)}. In contrast, reaction of arene ruthenium complexes [(eta6-arene)Ru(mu-Cl)Cl]2 (arene = C6H6, p-iPrC6H4Me and C6Me6) with the same ligands (L1 or L2) gives only the dinuclear complexes [{(eta6-C6H6)RuCl}2(mu-L)]2+ {L = L1 (9); L2 (10)}, [{(eta6-p-iPrC6H4Me)RuCl}2(mu-L)]2+ {L = L1 (11); L2 (12)} and [{(eta6-C6Me6)RuCl}2(mu-L)]2+ {L = L1 (13); L2 (14)}. All complexes were isolated as their hexafluorophosphate salts. The single-crystal X-ray crystal structure analyses of [7](PF6)2, [9](PF6)2 and [11](PF6)2 reveal a typical piano-stool geometry around the metal centers with six-membered metallo-cycle in which the 1,4-bis{bis(pyrazolyl)-methyl}benzene acts as a bis-bidentate chelating ligand.

Organelle-targeted photosensitization represents a promising approach in photodynamic therapy where the design of the active photosensitizer (PS) is very crucial. In this work, we developed a macromolecular PS with multiple copies of mitochondria-targeting groups and ruthenium complexes that displays highest phototoxicity toward several cancerous cell lines. In particular, enhanced anticancer activity was demonstrated in acute myeloid leukemia cell lines, where significant impairment of proliferation and clonogenicity occurs. Finally, attractive two-photon absorbing properties further underlined the great significance of this PS for mitochondria targeted PDT applications in deep tissue cancer therapy.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.32993-05-8, Name is Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II), molecular formula is C41H35ClP2Ru. In a Article，once mentioned of 32993-05-8, Recommanded Product: Chlorocyclopentadienylbis(triphenylphosphine)ruthenium(II)

A variety of piano-stool complexes of cyclopentadienyl ruthenium(II) with imidazole-based PN ligands have been synthesized starting from the precursor complexes [CpRu(C10H8)]PF6, [CpRu(NCMe) 3]PF6 and [CpRu(PPh3)2Cl]. PN ligands used are imidazol-2-yl, -4-yl and -5-yl phosphines. Depending on the ligand and precursor different types of coordination modes were observed; in the case of polyimidazolyl PN ligands these were kappa1P-monodentate, kappa2P,N-, kappa2N,N- and kappa3N,N,N- chelating and mu-kappaP:kappa2N,N-brigding. The solid-state structures of [CpRu(1a)2Cl ]·H2O (5 .H2O) and [{CpRu(mu-kappa2-N,N- kappa’1-P-2b)}2](C6H5PO 3H)2(C6H5PO3H 2)2, a hydrolysis product of the as well determined [{CpRu(2b)}2](PF6)2.2CH 3CN (7b.2CH3CN) were determined (1a = imidazol-2-yldiphenyl phosphine, 2b = bis(1-methylimidazol-2-yl)phenyl phosphine, 3a = tris(imidazol-2-yl)phosphine). Furthermore, the complexes [CpRu(L)2]PF6 (L = imidazol-2-yl or imidazol-4-yl phosphine) have been screened for their catalytic activity in the hydration of 1-octyne.

Electric Literature of 301224-40-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 301224-40-8, Name is (1,3-Dimesitylimidazolidin-2-ylidene)(2-isopropoxybenzylidene)ruthenium(VI) chloride, molecular formula is C31H38Cl2N2ORu. In a Article，once mentioned of 301224-40-8

The fundamental role played by actin In the regulation of eukaryotic cell maintenance and motility renders it a primary target for small-molecule intervention. in this arena, a class of potent cytotoxic cyclodepsipeptide natural products has emerged over the last quarter-century to stimulate the fields of biology and chemistry with their unique actin-stabilizing properties and complex peptide-polyketide hybrid structures. Despite considerable research effort, a structural basis for the activity of these secondary metabolites remains elusive, not least for the lack of high-resolution structural data and a reliable synthetic route to diverse compound libraries. in response to this, an efficient solid-phase approach has been developed and successfully applied to the total synthesis of Jasplakinolide and chondramide C and diverse analogues. The key macrocylization step was realized using ruthenium-catalyzed ring-closing metathesis (RCM) that in the course of a library synthesis produced discernible trends in metathesis reactivity and E/Z-selectivity, After optimization, the RCM step could be operated under mild conditions, a result that promises to facilitate the synthesis of more extensive analogue libraries for structure-function studies. The growth inhibitory effects of the synthesized compounds were quantified and structure-activity correlations established which appear to be in good alignment with relevant biological data from natural products. in this way a number of potent unnatural and simplified analogues have been found. Furthermore, potentially important stereochemical and structural components of a common pharmacophore have been identified and rationalized using molecular modeling. These data will guide in-depth mode-of-action studies, especially into the relationship between the cytotoxicity of these compounds and their actin-perturbing properties, and should inform the future design of simplified and functionalized actln stabilizers as well.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 301224-40-8 is helpful to your research., Electric Literature of 301224-40-8

A concise and convergent total synthesis of the highly cytotoxic marine natural products iejimalide A-D (1-4) is reported, which relies on an effective ring-closing metathesis (RCM) reaction of a cyclization precursor containing no less than 10 double bonds. Because of the exceptional sensitivity of this polyunsaturated intermediate and its immediate precursors toward acid, base, and even gentle warming, the assembly process hinged upon the judicious choice of protecting groups and the careful optimization of all individual transformations. As a consequence, particularly mild protocols for Stille as well as Suzuki reactions of elaborate coupling partners have been developed that hold considerable promise for applications in other complex settings. Moreover, a series of non-natural “iejimalide-like” compounds has been prepared, differing from the natural lead in the polar head groups linked to the macrolide’s N-terminus. With the aid of these compounds it was possible to uncover the hitherto unknown effect of iejimalide and analogues on the actin cytoskeleton. Their capacity to depolymerize this microfilament network rivals that of the latrunculins which constitute the standard in the field. Structural modifications of the peptidic terminus in 2 are thereby well accommodated, without compromising the biological effects. The iejimalides hence constitute an important new class of probe molecules for chemical biology in addition to their role as promising lead structures for the development of novel anticancer agents.

Two ruthenium(ii) polypyridyl complexes, [Ru(bpy)2(ptpn)] 2+ (1) (bpy = 2,2?-bipyridine, ptpn = 3-(1,10-phenanthroline-2- yl)-as-triazino[5,6-f]1,10-phenanthroline) and [Ru(phen)2(ptpn)] 2+ (2) (phen = 1,10-phenanthroline), were synthesized and characterized. Crystal structure analysis shows that complex 1 has a large planar aromatic area and possesses the potential to fit the geometric structure of G-quadruplex. The interaction of the G-quadruplex DNA with Ru(ii) complexes was explored by means of circular dichroism (CD), fluorescence resonance energy transfer (FRET) melting assay, competitive FRET assay and polymerase chain reaction (PCR) stop assay. The results indicated that complexes 1 and 2 both have the ability to promote the formation and stabilization of the human telomeric d[(TTAGGG)n] (HTG22) quadruplex and exhibit high G-quadruplex DNA selectivity over duplex DNA. The telomere repeat amplification protocol (TRAP) assay and long-term proliferation experiments further demonstrate that the Ru(ii) complexes are potent telomerase inhibitors and HeLa cell proliferation inhibitors.
