A new polymeric thin film by using electropolymerization: thin film of poly (phenazine-salen) obtained from 2,2 ‘-[1,2-ethanediylbis (nitrilomethylidyne)] -bis[4-amino-phenol]

In the last years, the study of the formation of a polymer containing multidentate Schiff-base ligand as subunits has been performed. In general, the electropolymerization occurs through the interaction between the phenyl rings and metallic centers. However, in this paper, we proposed a new polymeric thin film formation from 2,2’-[1,2-ethanediylbis(nitrilomethylidyne)]bis[4-amino-phenol] obtained by electropolymerization. The electropolymerization mechanism for poly(phenazine-salen) formation was based on the carbon-nitrogen coupling. The effect of experimental parameters such as scan rate, applied potential range, supporting electrolyte, and solvent type on the electropolymerization process was also evaluated. The poly(phenazine-salen) film was characterized by cyclic voltammetry and electrochemical impedance spectroscopy in an inert supporting electrolyte showing a redox couple ascribed to pyrazine moieties. The Mott-Schottky plot of the electropolymerized material indicated that the polymer is an n-type semiconductor. The results indicate a polymeric formation controlled by the electropolymerization parameters and the electrochemical behavior tuned by the ions insertion/extraction from supporting electrolyte.

The effect of molecular structure on the efficiency of 1,4-diazine-based D-(pi)-A push-pull systems for non-doped OLED applications

A series of novel D-A and D-pi-A push-pull systems based on a pyrazine and quinoxaline acceptor, bearing various electron-donating triphenylamine and carbazole moieties, are compared. A significant difference in electrochemical and photophysical properties was found depending on molecular structure. The compounds have strong solvatochmmic properties. Quinoxaline-containing systems exhibit delayed fluorescence (DF) in thermal vacuum deposition films. Despite the low quantum yield of fluorescence in the solid state (less than 10%), organic light-emitting diodes with sufficiently high efficiency (4.2 cd/A) have been fabricated on the basis of this push-pull systems. The best results were obtained for compounds exhibiting DF. The possible channel for increasing the efficiency of OLED can be associated with the hot excitons mechanism.

Efficacy of diquat treatments on Brazilian waterweed, effects on native macrophytes and water quality: A case study

Brazilian waterweed (Egeria densa Planch) is an invasive aquatic plant that has spread to 27 countries and 39 states in the United States. Movement has been facilitated by its popularity as an aquarium plant. Once established, the plant can adversely alter ecosystems. Brazilian waterweed spreads solely by fragmentation, which suggests that it may be easier to control than plants with propagules such as seeds, tubers, and turions. Herbicides have the potential to offer targeted control; however, their use on Brazilian waterweed has yielded mixed results, and collateral damage to desirable native species is a concern. Fence Rock Lake is a 7-ha manmade impoundment in Guilford, CT, USA. Brazilian waterweed was first documented in small patches in 2009. By 2014, the plant covered most of the littoral zone, and diquat (6,7-dihydrodipyrido[1,2-a:2′,1′-c]pyrazine-5,8-diium dibromide) was applied by bottom injection at a rate of 1.8 kg active ingredient ha(-1). Control of Brazilian waterweed and effects on native species were assessed by the point intercept method. One year after treatment, in 2015, Brazilian waterweed was absent from all points except one. Another diquat treatment was performed in an effort to eradicate the plant from the lake. In 2016 and 2017, no Brazilian waterweed was found. The native plant community was resilient with an increase in species richness from 11 pretreatment to 18 two years posttreatment. Combined native species showed little change in frequency of occurrence. Frequency of occurrence of individual native species exhibited losses, gains, or little change depending on species. Bottom injected diquat concentrations remained low near the bottom and highest near the surface. No diquat was detected 10 days after treatment. Littoral zone dissolved oxygen fell to near, but not below, levels considered harmful to warm water fish. Transparency and total phosphorus were not substantially affected by the diquat treatment. This study confirms that Brazilian waterweed is highly controllable in a Connecticut lake with two successive yearly diquat treatments.

Pentacyanoferrate(II) complex of pyridine-4-and pyrazine-2-hydroxamic acid as source of HNO: investigation of anti-tubercular and vasodilation activities

A pharmacophore design approach, based on the coordination chemistry of an intimate molecular hybrid of active metabolites of pro-drugs, known to release active species upon enzymatic oxidative activation, is devised. This is exemplified by combining two anti-mycobacterial drugs: pyrazinamide (first line) and delamanid (third line) whose active metabolites are pyrazinoic acid (PyzCOOH) and likely nitroxyl (HNO (or NO.)), respectively. Aiming to generate those active species, a hybrid compound was envisaged by coordination of pyrazine-2-hydroxamic acid (PyzCONHOH) with a Na-3[Fe-II(CN)(5)] moiety. The corresponding pentacyanoferrate(II) complex Na-4[Fe-II(CN)(5)(PyzCONHO(-))] was synthesized and characterized by several spectroscopic techniques, cyclic voltammetry, and DFT calculations. Chemical oxidation of this complex with H(2)O(2)was shown to induce the release of the metabolite PyzCOOH, without the need of theMycobacterium tuberculosis(Mtb) pyrazinamidase enzyme (PncA). Control experiments show that both H2O2- and N-coordinated pyrazine Fe(II)species are required, ruling out a direct hydrolysis of the hydroxamic acid or an alternative oxidative route through chelation of a metal center by a hydroxamic group. The release of HNO was observed using EPR spectroscopy in the presence of a spin trapping agent. The devised iron metal complex of pyrazine-2-hydroxamic acid was found inactive against an actively growing/non-resistantMtbstrain; however, it showed a strong dose-dependent and reversible vasodilatory activity with mostly lesser toxic effects than the reference drug sodium nitroprussiate, unveiling thus a potential indication for acute or chronic cardiovascular pathology. This is a priori a further indirect evidence of HNO release from this metal complex, standing as a possible pharmacophore model for an alternative vasodilator drug.

A Domino Fusion of an Organic Ligand Depended on Metal-Induced and Oxygen Insertion, Unraveled by Crystallography, Mass Spectrometry, and DFT Calculations

Herein, the reaction of (1-methyl-1 H-benzo[d]imidazol-2-yl)methanamine (L1) with Co(H2O)(6)Cl-2, in CH3CN at 120 degrees C, leading to the 2,3,5,6-tetrakis(1-methyl-1 H-benzo[d]imidazol-2-yl)pyrazine (3), isolated as a dimeric cluster {[Co-2(II)(3)Cl-4].2 CH3CN} (2), is reported. When O-2 and H2O are present, (1-methyl-1 H-benzo[d]imidazole-2-carbonyl)amide (HL1 ‘) is first formed and crystallized as [Co-III(L1)(2)(L1 ‘)]Cl-2.2 H2O (4) before fusion of HL1 ‘ with L1, giving 1-methyl-N-(1-methyl-1 H-benzo[d]imidazol-2-carbonyl)-1 H-benzo[d]imidazol-2-carboxamide (HL2 ”) forming a one-dimensional (1D) chain of [Co-3(II)(L2 ”)(2)Cl-4](n) (5). The combination of crystallography and mass spectrometry (ESI-MS) of isolated crystals and the solutions taken from the reaction as a function time reveal seven intermediate steps leading to 2, but six steps for 5, for which a different sequence takes place. Control and isotope labeling experiments confirm the two carbonyl oxygen atoms in 5 originate from both air and water. The dependence on the metals, compared with FeCl3.6 H2O leading to a stable triheteroarylmethyl radical, is quite astounding, which could be attributed to the different oxidation states of the metals and coordination modes confirmed by DFT calculations. This metal and valence dependent process is a very useful way for selectively obtaining these large molecules, which are unachievable by common organic synthesis.

Novel beta-Glucocerebrosidase Activators That Bind to a New Pocket at a Dimer Interface and Induce Dimerization

Genetic, preclinical and clinical data link Parkinson’s disease and Gaucher’s disease and provide a rational entry point to disease modification therapy via enhancement of beta-Glucocerebrosidase (GCase) activity. We discovered a new class of pyrrolo[2,3-b]pyrazine activators effecting both Vmax and Km. They bind to human GCase and increase substrate metabolism in the lysosome in a cellular assay. We obtained the first crystal structure for an activator and identified a novel non-inhibitory binding mode at the interface of a dimer, rationalizing the observed structure-activity relationship (SAR). The compound binds GCase inducing formation of a dimeric state at both endoplasmic reticulum (ER) and lysosomal pHs, as confirmed by analytical ultracentrifugation. Importantly, the pyrrolo[2,3-b]pyrazines have central nervous system (CNS) drug-like properties. Our findings are important for future drug discovery efforts in the field of GCase activation and provide a deeper mechanistic understanding of the requirements for enzymatic activation, pointing to the relevance of dimerization.

Catalyst plus chemodosimeter -> chemosensor: incorporation of catalytic functionality in an indicator displacement assay to realize reversible chemosensing detection

A new bimetallic complex, (CN)(3)Fe-II(tppz)(CuCl)-Cl-II (tppz = 2,3,5,6-tetra(2′-pyridyl)pyrazine) including an Fe(II)-diimine indicator and a dual functional Cu(II) receptor/catalyst, was synthesized to demonstrate the concept of indicator/catalyst displacement assay for the simultaneous detection and detoxification of cyanide. The catalytic degradation property in the assay was necessary for making the detecting system reversible, which the traditional indicator displacement assays could never achieve. After the realization of this new property, silica-gel-based solid-supporting complex 1 was fabricated for application in a device, which was demonstrated for its use in the naked-eye detection and degradation of cyanide in tap, river, and underground water samples in a repeatable and real-time manner, even in the presence of interfering anions (CH3COO-, N-3(-), HCO3-, Cl-, NO3-, HPO42-, SO42-, SCN-, and OCN-). Within 300 min, cyanide was quantitatively oxidized into the less toxic cyanate by 1 in the presence of H2O2. The detection limit of 1 for cyanide was found to be 1.16 x 10(-4) M (3.02 mg L-1).
