New Rh-2(II,II) Complexes for Solar Energy Applications: Panchromatic Absorption and Excited-State Reactivity

The new heteroleptic paddlewheel complexes cis-[Rh-2(mu-form)(2)(mu-np),][BF4](2), where form = p-ditolylformamidinate.(DTolF) or p-difluorobenzylforMamidinate (F-form) and np = 1,8-napthyridyine, and cis-Rh-2(mu-form)(2)(mu-npCOO)(2) (npCOO(-) = 1,8-naphthyridine-2-carboxylate), were synthesized and characterized. The complexes absorb strongly throughout the ultraviolet (lambda(max) = 300 nm, epsilon = 20 300 M-1 cm(-1)) and visible regions (lambda(max) = 640 nm epsilon = 3500 M-1 cm(-1)), Making them potentially useful new dyes with panchromatic light absorption for solar energy conversion applications. Ultrafast and nanosecond transient absorption and time resolved infrared spectroscopies were used to characterize the identity and dynamics of the excited states, where singlet and triplet Rh-2/form-to.maphthyridine, metal/ligand-to-ligand charge-transfer (ML-LCT) excited states were observed in all four complexes. The hpCOO(-) complexes exhibit red-shifted absorption profiles extending into the near-IR and undergo photoinitiated electron transfer to generate reduced methyl viologen, a species that persists in the presence of a sacrificial donor. The energy of the triplet excited state of each complex was estimated from energy-transfer quenching experiments using a series of organic triplet donors (E((3)pi pi*) from 1.83 to 0.78 eV). The singlet reduction (+0.6 V vs Ag/AgCl) potentials, and singlet and triplet oxidation potentials (-1.1 and 0.5 V vs Ag/AgC1, respectively) were determined. Based on the excited-state lifetimes and redox properties, these complexes represent a new class of light absorbers with potential application as dyes for charge injection into semiconductor solar cells and in sensitizer-catalyst assemblies for photocatalysis that operate with irradiation. from the ultraviolet to similar to 800 nm.

Immunomodulatory properties of 1,2-dihydro-4-hydroxy-2-oxo-1,8-naphthyridine-3-carboxamide derivative VL15

1,2-Dihydro-4-hydroxy-2-oxo-1,8-naphthyridine-3-carboxamide derivative VL15 has been recently developed as a selective cannabinoid CB2 receptor compound. Given the high selectivity of this compound at the cannabinoid CB2 receptor and the well-known protective function of this receptor in neurological disorders with autoimmune component like multiple sclerosis, we assessed the immunomodulatory properties of VL15. We assessed on activated peripheral blood mononuclear cells), proliferation and viability, cell cycle progression and measured activation markers and the expression of phosphorylated proteins. We found that VL15 reduces PBMC proliferation slightly affecting cell vitality, blocks the cell cycle progression and down-regulates the levels of T cell activation markers as well as the expression of phosphorylated proteins, NF-kB, IKK alpha beta, IKB alpha, ERK and Akt. VL15 was also used in drug permeability assays on Caco-2 cell line to evaluate its oral bioavailability and on MDCKII-hMDR1 cell lines to estimate its propensity to cross the blood-brain barrier by passive diffusion, in order to potentially maintain its efficiency on the infiltrating auto-reactive lymphocytes in the central nervous system. In these models, VL15 showed high intestinal absorption and good blood-brain barrier penetration. Our findings suggest that VL15, by controlling the immune response, might find potential application as orally administered drug in pathologies like multiple sclerosis.

Self-Assembly of TbPc2 Single-Molecule Magnets on Surface through Multiple Hydrogen Bonding

The complexation between 2-ureido-4[1H]-pyrimidinone (UPy) and 2,7-diamido-1,8-naphthyridine (NaPy) is used to promote the mild chemisorption of a UPy-functionalized terbium(III) double decker system on a silicon surface. The adopted strategy allows the single-molecule magnet behavior of the system to be maintained unaltered on the surface.

A novel Schiff-base fluorescent probe based on 1,8-naphthyridine and naphthalimide for Al3+

A novel Schiff-base, 7-acetamino-4-methyl-1,8-naphthyridine-2-carbaldehyde-(1′,8′-naphthalenedicarbonyl) hydrazone (HL) was designed, synthesized and evaluated as a fluorescent probe. The fluorescence properties of this probe towards various metal ions were investigated by UV-vis and fluorescence spectra in methanol. Test results indicated that the probe had high selectivity towards Al3+ over other commonly coexisting metal ions. Upon addition of Al3+, the fluorescence intensity at 414 nm increased significantly due to the inhibition of the PET process. The binding constant (Ma) of Al3+ binding to HL was calculated to be 5.64 x 10(4) M-1 from a Benesi-Hildebrand plot, and the detection limit(LOD) of HL for sensing Al3+ was calculated to be 0.13 mu M. The binding stoichiometry between HL and Al3+ was determined as 1:1 by the Job’s plot. Furthermore, the probe was chemically reversible for Al3+ in methanol by the addition of Na(2)EDTA solution.

Identification of a novel class of selective Tpl2 kinase inhibitors: 4-alkylamino-[1,7]naphthyridine-3-carbonitriles

We have previously reported the discovery and initial SAR of the [1,7]naphthyridine-3-carbonitriles and quinoline-3-carbonitriles as Tumor Progression Loci-2 (Tp12) kinase inhibitors. In this paper, we report new SAR efforts which have led to the identification of 4-alkylamino-[1,7]naphthyridine-3-carbonitriles. These compounds show good in vitro and in vivo activity against Tp12 and improved pharmacokinetic properties. In addition they are highly selective for Tp12 kinase over other kinases, for example, EGFR, MEK, MK2, and p38. Lead compound 4-cycloheptylamino-6-[(pyridin-3-ylmethyl)-amino]-[1,7]naphthyridine-3-carbonit-rile (30) was efficacious in a rat model of LPS-induced TNF-alpha production. (C) 2007 Elsevier Ltd.

Reversible Intramolecular Cyclization in Ruthenium Complexes Induced by Ligand-centered One-electron Transfer on Bidentate Naphthyridine: An Important Intermediate for Both Metal- and Organo-Hydride Species

Two types of dicarbonykuthenium(II) complexes bearing the unsymmetrical bidentate ligand 2-(2-pyridy1)-1,8-naphthyridine were prepared. The complexes undergo irreversible ligand-localized one-electron reduction to form redox-induced metal-lacyclization between the bidentate naphthyridyl ligand and the terminal CO ligand located nearby. Chemical reductions using NaBH4 were also performed to isolate the reaction products; the formation of both a metal hydride (Ru-H) and an organo hydride (C-H) species was confirmed.

Substituent effects in the decarboxylation reactions of coordinated arylcarboxylates in dinuclear copper complexes, [(napy)Cu-2(O2CC6H4X)](+)

A combination of gas-phase ion trap mass spectrometry experiments and density functional theory (DFT) calculations have been used to examine the role of substituents on the decarboxylation of 25 different coordinated aromatic carboxylates in binuclear complexes, [(napy)Cu-2(O2CC6H4X)](+), where napy is the ligand 1,8-naphthyridine (molecular formula, C8H6N2) and X=H and the ortho (o), meta (m) and para (p) isomers of F, Br, CN, NO2, CF3, OAc, Me and MeO. Two competing unimolecular reaction pathways were found: decarboxylation to give the organometallic cation [(napy)Cu-2(C6H4X)](+) or loss of the neutral copper benzoate to yield [(napy) Cu](+). The substituents on the aryl group influence the branching ratios of these product channels, but decarboxylation is always the dominant pathway. Density functional theory calculations reveal that decarboxylation proceeds via two transition states. The first enables a change in the coordination mode of the coordinated benzoate in [(napy)Cu-2(O2CC6H4X)](+) from the thermodynamically favoured O, O-bridged form to the O-bound form, which is the reactive conformation for the second transition state which involves extrusion of CO2 with concomitant formation of the CO2 coordinated organometallic cation, [(napy)Cu-2(C6H4X)(CO2)](+), which then loses CO2 in the final step to yield [(napy)Cu-2(C6H4X)](+). In all cases the barrier is highest for the second transition state. The o-substituted benzoates show a lower activation energy than the m-substituted ones, while the p-substituted ones have the highest energy, which is consistent with the experimentally determined normalised collision energy required to induce fragmentation of [(napy)Cu-2(O2CC6H4X)](+).

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5959-52-4, in my other articles.
