A Ruthenium(II) Complex as a Luminescent Probe for DNA Mismatches and Abasic Sites

[Ru(bpy)2(BNIQ)]2+ (BNIQ = Benzo[c][1,7]naphthyridine-1-isoquinoline), which incorporates the sterically expansive BNIQ ligand, is a highly selective luminescent probe for DNA mismatches and abasic sites, possessing a 500-fold higher binding affinity toward these destabilized regions relative to well-matched base pairs. As a result of this higher binding affinity, the complex exhibits an enhanced steady-state emission in the presence of DNA duplexes containing a single base mismatch or abasic site compared to fully well-matched DNA. Luminescence quenching experiments with Cu(phen)22+ and [Fe(CN)6]3- implicate binding of the complex to a mismatch from the minor groove via metalloinsertion. The emission response of the complex to different single base mismatches, binding preferentially to the more destabilized mismatches, is also consistent with binding by metalloinsertion. This work shows that high selectivity toward destabilized regions in duplex DNA can be achieved through the rational design of a complex with a sterically expansive aromatic ligand.

New ruthenium(II)-letrozole complexes as anticancer therapeutics

Novel ruthenium-letrozole complexes have been prepared, and cell viability of two human cancer cell types (breast and glioblastoma) was determined. Some ruthenium compounds are known for their cytotoxicity to cancer cells, whereas letrozole is an aromatase inhibitor administered after surgery to post-menopausal women with hormonally responsive breast cancer. A significant in vitro activity was established for complex 5¡¤Let against breast cancer MCF-7 cells and significantly lower activity against glioblastoma U251N cells. The activity of 5¡¤Let was even higher than that of 4, a compound analogous to the well-known drug RAPTA-C. Results from the combination of 5¡¤Let (or 4) with 3-methyladenine (3-MA) or with curcumin, respectively, revealed that the resultant cancer cell death likely involves 5¡¤Let-induced autophagy.

Kinetic selectivity of olefin metathesis catalysts bearing cyclic (alkyl)(amino)carbenes

The evaluation of ruthenium olefin metathesis catalysts 4-6 bearing cyclic (alkyl)(amino)carbenes (CAACs) in the cross-metathesis of cis-1,4-diacetoxy-2- butene (7) with allylbenzene (8) and the ethenolysis of methyl oleate (11) is reported. Relative to most NHC-substituted complexes, CAAC-substituted catalysts exhibit lower E/Z ratios (3:1 at 70% conversion) in the cross-metathesis of 7 and 8. Additionally, complexes 4-6 demonstrate good selectivity for the formation of terminal olefins versus internal olefins in the ethenolysis of 11. Indeed, complex 6 achieved 35 000 TONs, the highest recorded to date. CAAC-substituted complexes exhibit markedly different kinetic selectivity than most NHC-substituted complexes.

Reactions of the Lithiated Diphosphine tBu2P?P(SiMe3)Li with [(eta6-C6H6)RuCl2]2in the Presence of Tertiary Phosphines

tBu2P?P(SiMe3)Li reacted with [(eta6-C6H6)RuCl2]2at ?40 C in the presence of PR3(PR3= PEt3, PEt2Ph, PEtPh2) by the nucleophilic addition of the tBu2P?P(SiMe3) moiety to the benzene ring to yield solely the complexes [(R3P)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1). These products decomposed slowly at ambient temperature to yield benzene, Ru clusters, and small amounts of the dinuclear ruthenium complexes [{(R3P)2Ru}2(mu,eta2:2-P2)2Ru(PR3)2] (Ru?Ru) (6). Single-crystal X-ray diffraction studies of [(PhEt2P)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1b) and [(Ph2EtP)2Ru(Cl){eta5-C6H6(Me3SiP?PtBu2)}] (1c) revealed that the addition of the tBu2P?P(SiMe3) group occurred through an exo pathway. Complex 6a (R = Et) displays a planar rectangular P4system consisting of two P2units and a Ru?Ru distance that lies in the range of a single bond.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 37366-09-9, you can also check out more blogs about37366-09-9

Nitrosyl ruthenium complexes with general formula [RuCl3(NO)(P-P)] (P-P = {PPh2(CH2)nPPh2}, n = 1-3 and {PPh2-CH = CH-PPh2}). X-ray structure of [RuCl3(NO){PPh2(CH2)3PPh 2}]

Ruthenium(II) complexes with general formula [RuCl3(NO)(P-P)] were obtained in the solid state, where P-P = PPh2(CH2)nPPh2 (n = 1-3) and PPh2-CH = CH-PPh2. The 31P NMR spectra of these compounds measured in CH2Cl2 showed only singlets, consistent with a fac configuration containing two equivalent phosphorus atoms. However the X-ray diffraction data show that the [RuCl3(NO){PPh2(CH2)3PPh 2}] complex crystallizes in a mer configuration, where one of the phosphorus atoms is trans to the NO group, in a slightly distorted octahedral geometry.

Near-IR phosphorescent ruthenium(II) and iridium(III) perylene bisimide metal complexes

The phosphorescence emission of perylene bisimide derivatives has been rarely reported. Two novel ruthenium(II) and iridium(III) complexes of an azabenz-annulated perylene bisimide (ab-PBI), [Ru(bpy)2(ab-PBI)][PF6]2 1 and [CpIr-(ab-PBI)Cl]PF6 2 are now presented that both show NIR phosphorescence between 750-1000 nm in solution at room temperature. For an NIR emitter, the ruthenium complex 1 displays an unusually high quantum yield (Fp) of 11% with a lifetime (tp) of 4.2 ms, while iridium complex 2 exhibits Fp < 1% and tp =33 ms. 1 and 2 are the first PBI-metal complexes in which the spin-orbit coupling is strong enough to facilitate not only the Sn?Tn intersystem crossing of the PBI dye, but also the radiative T1?S0 transition, that is, phosphorescence.

Chemical and light-driven oxidation of water catalyzed by an efficient dinuclear ruthenium complex

Here splits the sun: A dinuclear ruthenium complex has been synthesized and employed to catalyze the homogeneous water oxidation (see picture; purple Ru, green Cl, blue N, red O). An exceptionally high turnover number was observed both for chemical (CeIV as the oxidant) and light-driven ([Ru(bpy)3]2+-type photosensitizers) water splitting.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.SDS of cas: 15746-57-3, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 15746-57-3, in my other articles.
