A 2-Styryl-1,8-naphthyridine derivative as a versatile fluorescent probe for the selective recognition of Hg2+ Ag+ and F- ions by tuning the solvent

A novel fluorescent probe 1 has been synthesized by a microwave reaction, and its ion-binding and fluorescence-sensing properties have been investigated under different solvent conditions. The analysis results indicated that probe 1 can act as a multiple analysis probe by simply tuning the solvent. Probe 1 exhibited high selectively toward Hg2+ through fluorescence quenching in H2O/DMF. In H2O/1,4-dioxane solution, probe 1 selectively recognized and discriminated between Ag+ and Hg2+ displaying ratiometric behaviour. Moreover, probe 1 readily recognized the anion F- via the ratiometric fluorescent mode in CH3CN. Furthermore, distinct colour changes were observed under UV light, which can be seen by the naked eye and thus used for distinguishing Hg2+, Ag+ and F- from the other ions screened herein using probe 1. Interestingly, almost pure white light emission was evident by simply tuning the F- anion-concentration, which makes this system a potential candidate for smart and tunable luminescent materials.

Realization of deep-blue TADF in sterically controlled naphthyridines for vacuum- and solution-processed OLEDs

Narrow-band deep-blue (emission peak < 460 nm) TADF emitters are in demand for commercial OLED display applications, yet the development of efficient emitters with low efficiency roll-off is very challenging. To address this issue, herein, we studied carbazole-naphthyridine (donor-acceptor)-based blue-emitting TADF compounds, which were designed by using both the H-bonding and sterically controlled charge-transfer (CT) interactions between D and A units. Methyl substitution employed at the first position oft-butyl-carbazole donors was found to affect CT strength and consequently the TADF properties of the studied compounds, enabling a significant reduction of delayed fluorescence lifetime (down to 3.1 mu s) and enhancement of reverse intersystem crossing rate (up to 10(6)s(-1)). The naphthyridines were demonstrated to hold great potential as deep-blue TADF emitters suitable for both vacuum- and solution-processed TADF OLEDs. The optimized devices with 7 wt% naphthyridine emitter in a weakly polar mCP host delivered external quantum efficiencies (EQEs) of up to similar to 17.6% and similar to 13.5% for vacuum- and solution-processed OLEDs, respectively. Unsubstituted naphthyridine exhibited deep-blue (lambda(max)< 460 nm) and narrow-band (FWHM = 66 nm) electroluminescence, whereas the more twisted methyl-substituted compound expressed broader band (FWHM > 80 nm) sky-blue (lambda(max)approximate to 480 nm) emission. The demonstrated emitters are among the best-performing conventional D-A-type blue/deep-blue TADF emitters in terms of EQE and efficiency roll-off properties of their devices.

Catalytic Conversion of Alcohols to Carboxylic Acid Salts and Hydrogen with Alkaline Water

A [RuH(CO)(py-NP)(PPh3)(2)]Cl (1) catalyst is found to be effective for catalytic transformation of primary alcohols, including amino alcohols, to the corresponding carboxylic acid salts and two molecules of hydrogen with alkaline water. The reaction proceeds via acceptorless dehydrogenation of alcohol, followed by a fast hydroxide/water attack to the metal-bound aldehyde. A pyridyl-type nitrogen in the ligand architecture seems to accelerate the reaction.

Synthesis, Structure, and Pharmacological Screening of 2,7-Naphthyridine Derivatives

An attempt to rearrange pyrrolo[3,4-c]pyridine-1,3-diones to the 2,7-naphthyridine ring under the conditions, described in only one report [I], gave compounds 7-9, but did not yield the expected 2,7- or 2,6-naphthyridine isomers. Important for the synthesis of the naphthyridine ring from pyrrolo[3,4-c]pyridine was that, of the two possible isomers, only 2,7- not 2,6-naphthyridine was obtained. Ethyl (4-R’-1,3-dioxo-6-phenyl-1,3-dihydro-2H-pyrrolo[3,4-c]pyridin-2-yl)acetate (5, 6, 10) treated with sodium ethoxide was rearranged by the Claisen-Dieckmann reaction to ethyl 4-hydroxy-8-R’-1-oxo-6-phenyl-1,2-dihydro-2,7-naphthyridine-3-carboxylate (13,14), where R’=methyl or ethoxy. The structures of the new compounds were confirmed by elemental analysis and NMR and IR spectra. The structure of 14 was also determined by X-ray crystallography to prove the presence of 2,7-naphthyridine isomer. The in vitro anticancer activities of the final 2,7-naphthyridines were tested at the US NCI (Bethesda, MD). Compound 13 exhibited cytostatic activity in vitro.

Discovery of N-(Pyridin-4-yl)-1,5-naphthyridin-2-amines as Potential Tau Pathology PET Tracers for Alzheimer’s Disease

A mini-HTS on 4000 compounds selected using 2D fragment-based similarity and 3D pharmacophoric and shape similarity to known selective tau aggregate binders identified N-(6-methylpyridin-2-yl)quinolin-2-amine 10 as a novel potent binder to human AD aggregated tau with modest selectivity versus aggregated beta-amyloid (A beta). Initial medicinal chemistry efforts identified key elements for potency and selectivity, as well as suitable positions for radiofluorination, leading to a first generation of fluoroalkyl-substituted quinoline tau binding ligands with suboptimal physicochemical properties. Further optimization toward a more optimal pharmacokinetic profile led to the discovery of 1,5-naphthyridine 75, a potent and selective tau aggregate binder with potential as a tau PET tracer.

New Strategy on Antimicrobial-resistance: Inhibitors of DNA Replication Enzymes

Background: Antimicrobial resistance is found in all microorganisms and has become one of the biggest threats to global health. New antimicrobials with different action mechanisms are effective weapons to fight against antibiotic-resistance. Objective: This review aims to find potential drugs which can be further developed into clinic practice and provide clues for developing more effective antimicrobials. Methods: DNA replication universally exists in all living organisms and is a complicated process in which multiple enzymes are involved in. Enzymes in bacterial DNA replication of initiation and elongation phases bring abundant targets for antimicrobial development as they are conserved and indispensable. In this review, enzyme inhibitors of DNA helicase. DNA primase, topoisomerases, DNA polymerase and DNA ligase were discussed. Special attentions were paid to structures, activities and action modes of these enzyme inhibitors. Results: Among these enzymes, type II topoisomerase is the most validated target with abundantinhibitors. For type II topoisomerase inhibitors (excluding quinolones), NBTIs and benzimidazole urea derivatives are the most promising inhibitors because of their good antimicrobial activity and physicochemical properties. Simultaneously, DNA gyrase targeted drugs are particularly attractive in the treatment of tuberculosis as DNA gyrase is the sole type II topoisomerase in Mycobacterium tuberculosis. Relatively, exploitation of antimicrobial inhibitors of the other DNA replication enzymes are primeval, in which inhibitors of topo III are even blank so far. Conclusion: This review demonstrates that inhibitors of DNA replication enzymes are abundant, diverse and promising, many of which can he developed into antimicrobials to deal with antibiotic resistance.

Highly Efficient Electron-Transporting/Injecting and Thermally Stable Naphthyridines for Organic Electrophosphorescent Devices

A series of 1,8-naphthyridine derivatives is synthesized and their electron-transporting/injecting (ET/EI) properties are investigated via a multilayered electrophosphorescent organic light-emitting device (OLED) using fac-tris(2-phenylpyridine)iridium [Ir(ppy)3] as a green phosphorescent emitter doped into a 4,4-N,N-dicarbazolebiphenyl (CBP) host with 4,4-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (a-NPD) as the hole-transporting layer, and poly(arylene ether sulfone) containing tetraphenylbenzidine (TPDPES) doped with tris(4-bromophenyl)ammonium hexachloroantimonate (TBPAH) as the hole-injecting layer. The turn-on voltage of the device is 2.5 V using 2,7-bis[3-(2-phenyl)-1,8-naphthyridinyl]-9,9-dimethylfluorene (DNPF), lower than that of 3.0 V for the device using a conventional ET material. The maximum current efficiency (CE) and power efficiency (PE) of the DNPF device are much higher than those of a conventional device. With the aid of a hole-blocking (HB) and exciton-blocking layer of bathocuproine (BCP), 13.213.7% of the maximum external quantum efficiency (EQE) and a maximum PE of 50.254.5 lm W1 are obtained using the naphthyridine derivatives; these values are comparable with or even higher than the 13.6% for conventional ET material. The naphthyridine derivatives show high thermal stabilities, glass-transition temperatures much higher than that of aluminum(III) bis(2-methyl-8-quinolinato)-4-phenylphenolate (BAlq), and decomposition temperatures of 510518 degrees C, comparable to or even higher than those of Alq3.

Cu(I) and Pb(II) complexes containing new tris(7-naphthyridyl)methane derivatives: Synthesis, structures, spectroscopy and geometric conversion

Two novel facial-capping tris-naphthyridyl compounds, 2-chloro-5-methyl-7-((2,4-dimethyl-1,8-naphthyridin-7(1H)-ylidene)(2,4-dimethyl-1,8-naphthyridin-7-yl))methyl-1,8-naphthyridine (L-1) and 2-chloro-7-((2-methyl-1,8-naphthyridin-7(1H)-ylidene)(2-methyl-1,8-naphthyridin-7-yl)) methyl-1,8-naphthyridine (L-2), as well as their Cu(I) and Pb(II) complexes, [CuLa(PPh3)]BF4 (1) (PPh3 = triphenylphosphine, L-a = bis(2,4-dimethyl-1,8-naphthyridin-7-yl)(2-chloro-5-methyl-1,8-naphthyridin-7-yl)methane), [CuLb(PPh3)]BF4 (2) (L-b = bis(2-methyl-1,8-naphthyridin-7-yl)(2-chloro-1,8-naphthyridin-7-yl)methane), [Pb(OLa)(NO3)(2)] (3) (OLa = bis(2,4-dimethyl-1,8-naphthyridin-7-yl)(2-chloro-5-methyl-1,8-naphthyridin-7-yl)methanol) and [Pb(L-b)(2)][Pb(CH3OH)(NO3)(4)] (4), have been synthesized and characterized by X-ray diffraction analysis, MS, NMR and elemental analysis. The structural investigations revealed that the transfer of the H-atom at the central carbon to an adjacent naphthyridine-N atom affords L-1 and L-2 possessing large conjugated architectures, and the central carbon atoms adopt the sp(2) hybridized bonding mode. The reversible hydrogen transfer and a geometric configuration conversion from sp(2) to sp(3) of the central carbon atom were observed when Pb(II) and Cu(I) were coordinated to L-1 or L-2. The molecular energy changes accompanying the hydrogen migration and titration of H+ to different receptor-N at L-1 were calculated by density functional theory (DFT) at the SCRF-B3LYP/6-311++G(d,p) level in a CH2Cl2 solution, and the observed lowest-energy absorption and emission for L-1 and L-2 can be tentatively assigned to an intramolecular charge transfer (ICT) transition in nature.
