Novel fluorescent nanosensors, based on a naphthyridine receptor, have been developed for the detection of guanosine nucleotides, and both their sensitivity and selectivity to various nucleotides were evaluated. The nanosensors were constructed from polystyrene nanoparticles functionalized by (N-(7-((3-aminophenyl) ethynyl)-1,8-naphthyridin- 2-yl) acetamide) via carbodiimide ester activation. We show that this naphthyridine nanosensor binds guanosine nucleotides preferentially over adenine, cytosine, and thymidine nucleotides. Upon interaction with nucleotides, the fluorescence of the nanosensor is gradually quenched yielding Stern-Volmer constants in the range of 2.1 to 35.9mM(-1). For all the studied quenchers, limits of detection (LOD) and tolerance levels for the nanosensors were also determined. The lowest (3 sigma) LOD was found for guanosine 3′,5′-cyclic monophosphate (cGMP) and it was as low as 150 ng/ml. In addition, we demonstrated that the spatial arrangement of bound analytes on the nanosensors’ surfaces is what is responsible for their selectivity to different guanosine nucleotides. We found a correlation between the changes of the fluorescence signal and the number of phosphate groups of a nucleotide. Results of molecular modeling and zeta-potential measurements confirm that the arrangement of analytes on the surface provides for the selectivity of the nanosensors. These fluorescent nanosensors have the potential to be applied in multi-analyte, array-based detection platforms, as well as in multiplexed microfluidic systems.

The photocatalytic reduction of carbon dioxide (CO2) to value-added chemicals is an attractive strategy to utilize CO2 as a feedstock for storing renewable energy, such as solar energy, in chemical bonds. Inspired by the biological function of the nicotinamide adenine dinucleotide redox couple (NAD(+)/NADH), we have been developing transition-metal complexes containing NAD(+)/NADH-functionalized ligands to create electro-and/or photochemically renewable hydride donors for the conversion of CO2 into value-added chemicals. Our previous fi ndings have provided insights for the development of photocatalytic organic hydride reduction reactions for CO2, however, further examples, as well as investigation, of these photo-driven NAD(+)/NADH-type hydrogenation and organic hydride transfer reactions are required not only to explore the mechanism in detail but also to develop a highly ef fi cient catalyst for arti fi cial photosynthesis. In this paper, we report the synthesis, characterization, and photo-induced NAD(+)/NADH conversion properties of a new ruthenium(II) complex, [Ru(bpy)(2)(Me-pn)](PF6)(2) (1), which contains a new NAD(+)-type ligand, Me-pn (2-methyl-6-(pyridin-2-yl)-1,5-naphthyridine). In addition, we have succeeded in the isolation of the corresponding two-electron reduced ruthenium(II) complex containing the NADH-type ligand Me-pnHH (2-methyl-6-(pyridin-2-yl)-1,4-dihydro-1,5-naphthyridine), i.e., [Ru(bpy)(2)(Me-pnHH)](PF6)(2) (1HH), by the photo-induced hydrogenation reaction of 1. Thus, in this study, a new photo-driven NAD(+)/NADH-type hydrogenation reaction for possible CO2 reduction using the NAD(+)/NADH redox function has been constructed.

Correlation between naphthyridine-like structures of polyacrylonitrile stabilized fibers and modulus of carbon fibers was investigated. It was found that naphthyridine-like structures, which is a kind of characteristics structure in the polyacrylonitrile stabilized fibers, influence the modulus of carbon fibers. The naphthyriding-like structures can convert to graphite layers, which induce the degree of graphitization and crystallite size to improve, so the more the naphthyriding-like structures form in the polyacrylonitrile stabilized fibers, the higher the modulus of carbon fibers is.

Homodinuclear transition-metal catalysts with a direct metal metal bond have the potential to induce novel reaction mechanisms and selectivity compared with mononuclear catalysts. The dinuclear (i-PrNDI)Ni-2(C6H6) (NDI = naphthyridine-diimine) complex catalyzes selective cyclotrimerization of monosubstituted alkynes, whereas mononuclear Ni catalysts generally give cyclotetramerization of alkynes. Density functional theory calculations reveal that the homodinuclear Ni-Ni catalyst induces a spin crossover mechanism that involves metallacyclopentadiene and nonclassical bridging metallacycloheptatriene intermediates. The cis configuration of the nonclassical bridging metallacycloheptatriene Ni-vinyl bonds results in alkyne cyclotrimerization by fast reductive elimination. This dinuclear mechanism differs from previously reported mononuclear Ni mechanisms and provides an explanation for cyclotrimerization versus cyclotetramerization selectivity and arene regioselectivity.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. Welcome to check out more blogs about 99-55-8, in my other articles. Recommanded Product: 2-Methyl-5-nitroaniline.
