An array of enantiomerically pure mononuclcear [Ru(bpy)2(dppz)] 2 + derivatives with 10,13-diaryl substituted dppz ligand has been synthesized and characterized (bpy = bipyridine, dppz = pyrido-[3,2-a:2?, 3?-c]phenazine). These new complexes exhibit substantially similar absorption spectra, resembling the parent complex [Ru(bpy)2(dppz)] 2 +, and the enantiomerically pure analogues show the similar CD spectra in buffer solution despite the structural difference.

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 15746-57-3 is helpful to your research., Synthetic Route of 15746-57-3

The purpose of the present investigation was to ascertain whether 3IL excited states with microsecond lifetimes are universally potent for photodynamic applications, and if these long-lived states are superior to their 3MLCT counterparts as in vitro PDT agents. A family of blue-green absorbing, Ru(II)-based transition metal complexes derived from the pi-expansive dppn ligand was prepared and characterized according to its photodynamic activity against HL-60 cells, and toward DNA in cell-free media. Complexes in this series that are characterized by low-energy and long-lived 3IL excited states photocleaved DNA with blue, green, red, and near-IR light. This panchromatic photodynamic effect translated to in vitro multiwavelength photodynamic therapy (PDT) with red-light cytotoxicities as low as 1.5 muM (EC50) for the parent complex and 400 nM for its more lipophilic counterpart. This potency is similar to that achieved with Ru(II)-based dyads containing long-lived 3IL excitons located on appended pyrenyl units, and appears to be a general property of sufficiently long-lived excited states. Moreover, the red PDT observed for certain members of this family was almost 5 times more potent than Photofrin with therapeutic indices 30 times greater. Related Ru(II) complexes having lowest-lying 3MLCT states of much shorter duration (?1 mus) did not yield DNA photodamage or in vitro PDT with red or near-IR light, nor did the corresponding Os(II) complex with a submicrosecond 3IL excited state lifetime. Therefore, metal complexes that utilize highly photosensitizing 3IL excited states, with suitably long lifetimes (? 1 mus), are well-poised to elicit PDT at wavelengths even where their molar extinction coefficients are very low (<100 M-1 cm-1). Herein we demonstrate that such unexpected reactivity gives rise to very effective PDT in the typical therapeutic window (600-850 nm). Interested yet?

Abstract Novel ruthenium complexes Ru(L)(bpy)2(PF6)2 and platinum organometallic complexes Pt(L)(-?-C6H5CH3)2 with bis-(pyridinyl)ethynyl-phenanthrolines (L = 3,8-bis[2-(3-pyridinyl)ethynyl]-1,10-phenanthroline or 3,8-bis[2-(4-pyridinyl)ethynyl]-1,10-phenanthroline) that function as metalloligands by extra pyridyl units have been prepared using respective synthetic methods. These complexes have broad absorption bands assignable to the MLCT band as the main contributing factor in the 400 to 550 nm wavelength region. Furthermore, these complexes show phosphorescence centered around 680 nm upon excitation at 425 nm. These emissions were assigned to a triplet MLCT-based luminescence for the ruthenium complexes, while a triplet MLCT as the main element, including the interligand charge transfer as the minor element, was assigned for the platinum organometallic complexes. The quantum yields of the emission of the present ruthenium complexes were relatively high, and these complexes are exactly phosphorescent dyes, although the emission intensities of the platinum complexes are poor. These two types of complexes are capable of selective photophysical detection of some metal ions and can serve as metalloligands in the construction of supramolecular metallocycles.

Thioredoxin reductase (TrxR), a major component of the thioredoxin system, makes a critical role in regulating cellular redox signaling and is found to be overexpressed in many human cancer cells. TrxR has become an attractive target for anticancer agents. In this work, three Ru(II) complexes with salicylate as ligand, [Ru(phen)2(SA)] (phen = 1,10-phenanthroline, SA = salicylate, 1), [Ru(dmb)2(SA)] (dmb = 4,4?-dimethyl-2,2?-bipyridine, 2) and [Ru(bpy)2(SA)] (bpy = 2,2?-bipyridine, 3), were synthesized and characterized. The anticancer effect exerted by them was evaluated. Complex 1 was found to exhibit obvious anticancer activity, in comparison with cisplatin, against cancer cell lines, while displaying low toxicity to the normal cell line BEAS-2B. The mechanism of complex 1 cancer cell growth suppress was investigated in A549 cells. Complex 1 exerted its anticancer through inducing apoptosis and triggering cell cycle arrest at the G0/G1 phase. Complex 1 can selectively inhibit TrxR activity and thus promote the generation and accumulation of reactive oxygen species (ROS), which subsequently trigger mitochondrial dysfunction and DNA damage, activate oxidative stress-sensitive mitogen activated protein kinase (MAPK), and suppress the protein kinase B (PKB or AKT) signal pathway, resulting in apoptosis in A549 cells.

A ruthenium trinuclear polyazine complex was synthesized and subsequently immobilized through complexation to a graphene oxide support containing phenanthroline ligands (GO-phen). The developed photocatalyst was used for the photocatalytic reduction of CO2 to methanol, using a 20 watt white cold LED flood light, in a dimethyl formamide-water mixture containing triethylamine as a reductive quencher. After 48 h illumination, the yield of methanol was found to be 3977.57 ± 5.60 mumol gcat -1. The developed photocatalyst exhibited a higher photocatalytic activity than graphene oxide, which provided a yield of 2201.40 ± 8.76 mumol gcat-1. After the reaction, the catalyst was easily recovered and reused for four subsequent runs without a significant loss of catalytic activity and no leaching of the metal/ligand was detected during the reaction.

Metal-coordinated “gamma-lactam-capped” and “imide-capped” 1,10-phenanthroline ligands are reported. Whereas the imide-functionalized ligand 1,10-phenanthroline-5,6-carboximide could not be obtained as a free ligand, probably due to its extremely low solubility, we developed a protocol to first introduce the more soluble 1,10-phenanthrolino[5, 6-c]pyrrole in the ligand sphere of cyclometalated iridium(III) complexes, followed by the oxidation of the pyrrole moiety to a maleimide utilizing a peroxybenzoic acid. The hydrogen bond donor-acceptor properties of the new ligands should make them suitable building blocks for the design of metal-based protein binders. Furthermore, we unexpectedly found that bis-cyclometalated iridium(III) complexes coordinated to 1,10-phenanthroline-5,6-carboximide display luminescence properties that are dependent on the protonation state of the maleimide NH group. It can be envisioned to exploit this behavior for the real-time monitoring of hydrogen bonding interactions in biological systems.

The 3,6-bis(2′-pyridyl)pyridazine (dppnH) ligand can be used as a bridging ligand in two different ways: (i) it can coordinate two metal ions on the same side by means of two N-N chelating moieties, or (ii) it can coordinate two metal ions on opposite sides by means of N-N and C~-N chelating moieties, the second one resulting from metallation at the pyridazine ring. We have exploited the latter possibility to prepare the hexanuclear complex [{(bpy)2Ru(/t-dppn)}2Rh(/iCI)2Rh{(/i-dppn)Ru(bpy)2}2]8t (1) as the PFe salt. The preparation of 1 was performed by reacting the mononuclear [Ru(bpy)2(dppnH]2t complex with RhCI3. The novel polynuclear complex 1 contains four Ru(ll)-polypyridine-type peripheral units linked to a core made of two cyclometallated Rh(lll) units bridged by two Cl~ ions. The absorption, emission, and redox properties of 1 have been examined and are compared with the properties displayed by appropriate model compounds. 1 shows absorption bands in the UV and visible spectral regions and a strong phosphorescence band both in solution at room temperature (Amax = 657 nm, $ = 0.038, r = 925 ns) and in a rigid matrix at 77 K (Amax = 632 nm, r = 4.5 p,s), which is assigned to the 3MLCT level of the Ru-based peripheral units. Electrochemical experiments have evidenced an oxidation wave at +1.31 V vs SCE, assigned to the metal-centered oxidation of the four (weakly interacting) Ru-based units. On reduction, a complex pattern of ligand-centered processes is observed, starting with a twoelectron wave at -1.10V, assigned to reduction of the N-N chelating moieties of two remote bridging ligands. The hexanuclear compound 1 is particularly interesting since, by analogy with other Cl~ bridged Rh(lll) cyclometallated complexes, it is expected to undergo cleavage of the Cl~ bridges upon reaction with N-N type chelating ligands. It can therefore be used as a building block for the synthesis of mixed-metal complexes of high nuclearity. ‘ CNRS-Gauthier-Villars.
