Development of a new class of luminescent materials that show high-speed response, high charge carrier mobility, and high brightness is desirable toward realization of next generation of devices, such as electrically pumped organic lasers, visible light communication instruments, and organic light-emitting transistors. In this paper, high-speed organic light-emitting diodes (OLEDs) and high-performance hybrid light-emitting transistors from a new type of solution processable luminescent material, poly[thiophene-2,5-diyl-alt-5,10-bis((2-hexyldecyl)oxy)dithieno[3,2-c:3 ‘,2 ‘-h][1,5]naphthyridine-2,7-diyl] (PTNT), are reported. The OLEDs based on PTNT polymer exhibit a peak brightness of 8 x 10(5) cd m(-2) and 40 MHz modulation frequency under 10 ns pulse operation. This modulation frequency is significantly higher than that of commercially available LEDs, used for visible light communication. Additionally, solution-processed area-emitting hybrid light-emitting transistors with an external quantum yield of 0.25% at brightness of 250 cd m(-2) are demonstrated. Finally, the paper provides device physics and optoelectronic properties of PTNT polymer using ultraviolet photon spectroscopy, inversed photoelectron spectroscopy, and photophysical measurements.

On the basis of the good anti-inflammatory properties shown by the 9-alkyl-N,N-dialkyl-5-(alkylamino)[1,2,4]triazolo[4,3-a][1,8]naphthyridine-6-carboxamides 1, a series of analogues of such compounds, in which the 9-alkyl substituent was replaced by an ester or amide group (compounds 3a-i), was prepared and tested (inhibition of carrageenan-induced paw edema in the rat). Also two 5-(N-alkylN-acylamino) derivatives (compounds 4a,b) were synthesized and evaluated for the same purpose. Even though the general trend for these new [1,2,4]triazolo[4,3-a][1,8]naphthyridine derivatives was a decrease in activity compared with compounds 1, some of the new synthesized compounds exhibited still good anti-inflammatory properties.

In a document, author is Wright, Galen E. B., introduce the new discover, Quality Control of (R)-BoroLeu-(+)-Pinanediol trifluoroacetate.

Background Huntington’s disease is a fatal neurodegenerative disorder that is caused by CAG-CAA repeat expansion, encoding polyglutamine, in the huntingtin (HTI) gene. Current age-of-clinical-onset prediction models for Huntington’s disease are based on polyglutamine length and explain only a proportion of the variability in age of onset observed between patients. These length-based assays do not interrogate the underlying genetic variation, because known genetic variants in this region do not alter the protein coding sequence. Given that individuals with identical repeat lengths can present with Huntington’s disease decades apart, the search for genetic modifiers of clinical age of onset has become an active area of research. Recent developments Results from three independent genetic studies of Huntington’s disease have shown that glutamine-encoding CAA variants that interrupt DNA CAG repeat tracts, but do not alter polyglutamnine length or polyglutamine homogeneity, are associated with substantial differences in age of onset of Huntington’s disease in carriers. A variant that results in the loss of CAA interruption is associated with early onset and is particularly relevant to individuals that carry alleles in the reduced penetrance range (ie, CAG 36-39). Approximately a third of clinically manifesting carriers of reduced penetrance alleles, defined by current diagnostics, carry this variant. Somatic repeat instability, modified by interrupted CAG tracts, is the most probable cause mediating this effect. This relationship is supported by genome-wide screens for disease modifiers, which have revealed the importance of DNA-repair genes in Huntington’s disease (ie, FAN1, LIG1, MLH1, MSH3, PMS1, and PMS2). Where next? Focus needs to be placed on refining our understanding of the effect of the loss-of-interruption and duplication-of-interruption variants and other interrupting sequence variants on age of onset, and assessing their effect in disease-relevant brain tissues, as well as in diverse population groups, such as individuals from Africa and Asia. Diagnostic tests should be augmented or updated, since current tests do not assess the underlying DNA sequence variation, especially when assessing individuals that carry alleles in the reduced penetrance range. Future studies should explore somatic repeat instability and DNA repair as new therapeutic targets to modify age of onset in Huntington’s disease and in other repeat-mediated disorders. Disease-modifying therapies could potentially be developed by therapeutically targeting these processes. Promising approaches include therapeutically targeting the expanded repeat or directly perturbing key DNA-repair genes (eg, with antisense oligonucleotides or small molecules). Targeting the CAG repeat directly with naphthyridine-azaquinolone, a compound that induces contractions, and altering the expression of MSH3, represent two viable therapeutic strategies. However, as a first step, the capability of such novel therapeutic approaches to delay clinical onset in animal models should be assessed.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind.

In a article, author is Bacher, Felix, introduce new discover of the category.

A synthetic route to unsymmetrical 1,8-naphthyridine spacer based ligands is presented. Reaction of a 7-ethyldipyridyl-1,8-naphthyridine-2-carboxaldehyde intermediate with 2-aminophenol or 4,6-di-tert-butyl 2-aminophenol led to the formation of ligands, HL1 and HL2, respectively. Both combined two distinct binding sites: a dipyridyl and an iminophenol site linked through a 1,8-naphthyridine spacer. Treatment of HL1 with copper(II) triflate in the presence of triethylamine/H2O in acetonitrile afforded a tetranuclear complex (1(tox)center dot 2CH(3)CN). X-ray analysis revealed that the structure is constituted by the association of two identical dinuclear units in which the imine is oxidized to an amide group during the complexation. The coordination capabilities of the corresponding free amide ligands H2L1ox and H2L2ox, prepared by an independent route, were explored using copper(II) triflate in the presence of triethylamine/H2O. With the amide ligand, H2L1ox, a similar tetranuclear copper complex (1(tox)center dot 2DMF) compared to the one isolated after complexation with the imine ligand HL1 was formed, as evidenced by X-ray diffraction studies. In contrast, H2L2ox, where the amido phenol arm exhibits two additional tert-butyl groups, has allowed the formation of a trinuclear copper complex (2(triox)center dot H2O).

Wahidur, once mentioned the application of 61-19-8, Name is Adenosine 5′-monophosphate, molecular formula is C10H14N5O7P, molecular weight is 347.2212, category is naphthyridine. Now introduce a scientific discovery about this category, Name: Adenosine 5′-monophosphate.

Reaction of 2-imidazolyl-5,7-dimethyl-1,8-naphthyridine (L(1)) with [Rh(COD) Cl](2) (COD = 1,5-cyclooctadiene) affords the dinuclear complex [Rh(COD)Cl](2)(mu-L(1)) (1). Elimination of chloride from the metal coordination sphere leads to a self-assembled tetranuclear macrocycle [Rh(COD)L(1)](4)[ClO(4)](4) (2). A subtle alteration in the ligand framework results in the polymeric chain compound {Rh(COD)(L(2))}(n)(PF(6))(n) (3) (L(2) = 2-imidazolyl-3-phenyl-1,8-naphthyridine). In all these complexes, the imidazole nitrogen and one of the naphthyridine nitrogen (away from the imidazole substituent) bind the metal. The ‘parallel’ and ‘perpendicular’ dispositions of nitrogens are observed in these compounds contributing to different Rh center dot center dot center dot Rh separations. The L(1) ligand adopts planar configuration, whereas the naphthyridine-imidazole rings deviate from planarity in L(2) yielding a polymeric structure. The extent of deviation is less in the polymeric structure {Mo(2)(OAc)(4)(L(2))}(n) (4) in which the ligand exhibits weak axial interactions to the metal. (C) 2011 Elsevier B.V. All rights reserved.

A novel class of chiral naphthyridine diimine ligands (NDI*) readily accessible fromC(2)-symmetric 2,6-di-(1-arylethyl)anilines is described. The utility of these ligands, particularly one with fluorinated aryl side arms, is demonstrated by a reductive Ni-catalyzed enantioselective alkylidene transfer reaction from 1,1-dichloroalkenes to olefins.

Aim: Simultaneous modulation of several key targets of the pathological network of Alzheimer’s disease (AD) is being increasingly pursued as a promising option to fill the critical gap of efficacious drugs against this condition. Materials & methods: A short series of compounds purported to hit multiple targets of relevance in AD has been designed, on the basis of their distinct basicities estimated from high-level quantum mechanical computations, synthesized, and subjected to assays of inhibition of cholinesterases, BACE-1, and A beta 42 and tau aggregation, of antioxidant activity, and of brain permeation. Results: Using, as a template, a lead rhein-huprine hybrid with an interesting multitarget profile, we have developed second-generation compounds, designed by the modification of the huprine aromatic ring. Replacement by [1,8]-naphthyridine or thieno[3,2-e] pyridine systems resulted in decreased, although still potent, acetylcholinesterase or BACE-1 inhibitory activities, which are more balanced relative to their A beta 42 and tau antiaggregating and antioxidant activities. Conclusion: Second-generation naphthyridine-and thienopyridine-based rhein-huprine hybrids emerge as interesting brain permeable compounds that hit several crucial pathogenic factors of AD.
