Cai, Xue published the artcileDimeric phthalocyanine-involved double-decker complex-based electrochemical sensor for simultaneous detection of acetaminophen and ascorbic acid, Application of Phthalonitrile, the main research area is acetaminophen ascorbic acid phthalocyanine double decker complex electrochem sensor.

An electrochem.sensor for simultaneous detection of acetaminophen (APAP) and ascorbic acid (AA) is firstly developed by using the self-assembled film of a novel dimeric bis(phthalocyaninato) europium complex, [{Pc(SC2H5)8}Eu{BiPc(SC2H5)12}Eu{Pc(SC2H5)8}] (1) coated onto ITO (fim-1/ITO) fabricated through a solution-processing quasi-LangmuirShafer (QLS) protocol. A combination of unique sandwich mol.structure with extented π-conjugated system and J-type aggregates with quite uniform nanograins (ca.15 nm) formed on ITO substrate render the film of 1 the excellent charge transfer ability and abundant electroactive sites, resulting in sensitive detection of APAP and AA with the good sensitivities of 254 and 85.6 mA μM-1 cm-2 and low detection limits of 1.3 and 3.7 μM for APAP and AA resp. More importantly, a simultaneous determinationof APAP and AA at a coexisting system of APAP and AA is also achieved with the still good sensitivities of 317 and 64.7 mA μM-1 cm-2, and low detection limits of 1.0 and 4.9 μM for APAP and AA resp. This work represents the first example of tetrapyrrole-based organicsemiconductor electrochem.sensor for simultaneous detection of APAP and AA with excellent sensing performance, implying the great application potential of electroactive sandwich rare earth tetrapyrrole compoundsin the nonenzymic electrochem.sensors.

Klyamer, Darya published the artcileVanadyl phthalocyanine films and their hybrid structures with Pd nanoparticles: structure and sensing properties, Product Details of C8H4N2, the main research area is vanadyl phthalocyanine film hybrid structure palladium nanoparticle sensing property; ammonia; chemiresistive sensors; hydrogen; palladium nanoparticles; thin films; vanadyl phthalocyanine.

In this work, thin films of vanadyl phthalocyanines (VOPc and VOPcF4) are studied as active layers for the detection of gaseous ammonia and hydrogen. The effect of F-substituents on the structural features of vanadyl phthalocyanine films and their sensor response toward ammonia (10-50 ppm) and hydrogen (100-500 ppm) is investigated by X-ray diffraction (XRD) and chemiresistive methods, resp. It is shown that the sensor response of VOPcF4 films to ammonia is 2-3 times higher than that of VOPc films. By contrast, the sensor response to hydrogen is higher in the case of VOPc films. Apart from this, the hybrid structures of vanadyl phthalocyanine films with Pd nanoparticles deposited on their surface by a chem. vapor deposition method are also tested to reveal the effect of Pd nanoparticles on the sensitivity of VOPc films to hydrogen. Deposition of Pd nanoparticles on the surface of VOPc films leads to the noticeable increase of their sensitivity to hydrogen.

Negri, Laisa Bonafim published the artcilePhotobiomodulation combined with photodynamic therapy using ruthenium phthalocyanine complexes in A375 melanoma cells: Effects of nitric oxide generation and ATP production, Application of Phthalonitrile, the main research area is ruthenium phthalocyanine nitric oxide ATP photodynamic therapy melanoma photobiomodulation; Light irradiation therapy; Metal-based drug; Nitrosyl ruthenium-phthalocyanine complex; Photobiomodulation.

Light irradiation has been used in clin. therapy for several decades. In this context, photobiomodulation (PBM) modulates signaling pathways via ROS, ATP, Ca2+, while photodynamic therapy (PDT) generates reactive oxygen species by excitation of a photosensitizer. NO generation could be an important tool when combined with both kinds of light therapy. By using a metal-based compound, we found that PBM combined with PDT could be a beneficial cancer treatment option. This paper used two types of ruthenium compounds, ([Ru(Pc)], Pc = phthalocyanine) and trans-[Ru(NO)(NO2)(Pc)]. The UV-vis spectra of both complexes displayed a band in the 660 nm region. In the case of 0.5 μM trans-[Ru(NO)(NO2)(Pc)], light irradiation at the Q-band reduced the percentage of viable human melanoma (A375) cells to around 50% as compared to [Ru(Pc)]. We hypothesized that these results were due to a synergistic effect between singlet oxygen and nitric oxide. Similar experiments performed with PDT (660 nm) combined with PBM (850 nm) induced more photocytotoxicity using both [Ru(Pc)] and trans-[Ru(NO)(NO2)(Pc)]. This was interpreted as PBM increasing cell metabolism (ATP production) and the consequent higher uptake of the ruthenium phthalocyanine compounds and more efficient apoptosis. The use of metal-based photosensitizers combined with light therapy may represent an advance in the field of photodynamic therapy.

Wang, Bing published the artcileNovel axial substituted subphthalocyanines and their TiO2 nanocomposites: Synthesis, structure, theoretical calculation and their photocatalytic properties, Recommanded Product: Phthalonitrile, the main research area is titanium dioxide nanocomposite electronic transition photocatalytic property.

For the study, we reported the synthesis and characteristics of two subphthalocyanines H12SubPcB-Br (SubPc-1) and H12SubPcB-OPh2OH (SubPc-2), in addition to their resp. composites with nano-titanium dioxide (TiO2). SubPc-1 and SubPc-2 were composed by the measure of hydrotherm with toluene on the scene. The approaches of DFT and TD-DFT were used to research the electronic structure and optical spectra in the subphthalocyanines. The photocatalytic activities of pristine TiO2 particle and TiO2/SubPc composites went through the test to degrade methyl orange (MO) and bromophenol blue (BB) in irradiance of visible light. It is demonstrated from the results that all the TiO2/SubPc photocatalysts exhibited further improved efficiency approx. 72.4% and 29.2% for the degradation of MO and BB under visible light, in comparison with pure TiO2. Furthermore, the reusability studies showed that photocatalytic activity could be maintained over 84% after five recycles.

McEwen, Charles N. published the artcileSublimation Driven Ionization for Use in Mass Spectrometry: Mechanistic Implications, Synthetic Route of 91-15-6, the main research area is mass spectrometry ionization sublimation driven.

Sublimation has been known at least since the middle ages. This process is frequently taught in schools through the use of phase diagrams. Astonishingly, such a well-known process appears to still harbor secrets. Under conditions in which compound sublimation occurs, gas-phase ions are frequently detected using mass spectrometry. This was exploited in matrix-assisted ionization in vacuum (vMAI) by adding analyte to subliming compounds used as matrixes. Good vMAI matrixes were those that ionize the added analyte with high sensitivity, but even matrixes that fail this test often produce ions of likely matrix impurities suggesting that they may be good matrixes for some compound types. We also show that binary matrixes may be manipulated to provide desired properties such as fast analyses and improved sensitivity. These results imply that sublimation in some cases is more complicated than just mols. leaving a surface and that understanding the phys. force responsible, and how the nonvolatile compound becomes charged, could lead to improved ionization efficiency for mass spectrometry. Here we provide insights into this process and an explanation of why this unexpected phenomenon has not previously been reported.

Lee, Chuping published the artcileToward understanding the ionization mechanism of matrix-assisted ionization using mass spectrometry experiment and theory, Application In Synthesis of 91-15-6, the main research area is ionization mechanism MALDI mass spectrometry experiment theory.

Rationale : Matrix-assisted ionization (MAI) mass spectrometry does not require voltages, a laser beam, or added heat to initiate ionization, but it is strongly dependent on the choice of matrix and the vacuum conditions. High charge state distributions of nonvolatile analyte ions produced by MAI suggest that the ionization mechanism may be similar to that of electrospray ionization (ESI), but different from matrix-assisted laser desorption/ionization (MALDI). While significant information is available for MAI using mass spectrometers operating at atm. and intermediate pressure, little is known about the mechanism at high vacuum. Methods : Eleven MAI matrixes were studied on a high-vacuum time-of-flight (TOF) mass spectrometer using a 266. nm pulsed laser beam under otherwise typical MALDI conditions. Detailed comparisons with the commonly used MALDI matrixes and theor. prediction were made for 3-nitrobenzonitrile (3-NBN), which is the only MAI matrix that works well in high vacuum when irradiated with a laser. Results : Screening of MAI matrixes with good absorption at 266 nm but with various degrees of volatility and laser energies suggests that volatility and absorption at the laser wavelength may be necessary, but not sufficient, criteria to explain the formation of multiply charged analyte ions. 3-NBN produces intact, highly charged ions of nonvolatile analytes in high-vacuum TOF using a laser, demonstrating that ESI-like ions can be produced in high vacuum. Theor. calculations and mass spectra suggest that thermally induced proton transfer, which is the major ionization mechanism in MALDI, is not important with the 3-NBN matrix at 266 nm laser wavelength. 3-NBN:analyte crystal morphol. is, however, important in ion generation in high vacuum. Conclusions : The 3-NBN MAI matrix produces intact, highly charged ions of nonvolatile compounds in high-vacuum TOF mass spectrometers with the aid of ablation and/or heating by laser irradiation, and shows a different ionization mechanism from that of typical MALDI matrixes.

Molaei, Somayeh published the artcileOrdered mesoporous SBA-15 functionalized with yttrium(III) and cerium(III) complexes: Towards active heterogeneous catalysts for oxidation of sulfides and preparation of 5-substituted 1H-tetrazoles, Safety of Phthalonitrile, the main research area is sulfoxide tetrazole preparation SBA 15 functionalized yttrium cerium complex; sulfide nitrile oxidation.

Mesoporous SBA-15 was synthesized and modified with 3-chloropropyltrimethoxysilane and then used in immobilization of creatinine groups, which were employed to introduce Y3+ and Ce3+ to give rise to two novel yttrium and cerium catalysts: SBA-15@Creatinine@M (M = Y and Ce). The structures of the SBA-15@Creatinine@M catalysts were determined using various techniques. These catalysts offered outstanding catalytic performances in the oxidation of sulfides to sulfoxides and in the preparation of 5-substituted 1H-tetrazoles. An important characteristic of the SBA-15@Creatinine@M catalysts is that they are very stable without a considerable decrease in their catalytic performance lasting seven cycles.

Kamiya, Yusuke published the artcilePrediction of permeability across intestinal cell monolayers for 219 disparate chemicals using in vitro experimental coefficients in a pH gradient system and in silico analyses by trivariate linear regressions and machine learning, Computed Properties of 91-15-6, the main research area is intestinal cell monolayer permeability silico TLR machine learning; Caco-2 cells; Machine learning; Multivariate analysis; Octanol–water distribution coefficient; Permeability.

For medicines, the apparent membrane permeability coefficients (Papp) across human colorectal carcinoma cell line (Caco-2) monolayers under a pH gradient generally correlate with the fraction absorbed after oral intake. Furthermore, the in vitro Papp values of 29 industrial chems. were found to have an inverse association with their reported no-observed effect levels for hepatotoxicity in rats. In the current study, we expanded our influx permeability predictions for the 90 previously investigated chems. to both influx and efflux permeability predictions for 207 diverse primary compounds, along with those for 23 secondary compounds Trivariate linear regression anal. found that the observed influx and efflux logPapp values determined by in vitro experiments significantly correlated with mol. weights and the octanol-water distribution coefficients at apical and basal pH levels (pH 6.0 and 7.4, resp.) (apical to basal, r = 0.76, n = 198; and basal to apical, r = 0.77, n = 202); the distribution coefficients were estimated in silico. Further, prediction accuracy was enhanced by applying a light gradient boosting machine learning system (LightGBM) to estimate influx and efflux logPapp values that incorporated 17 and 19 in silico chem. descriptors (r = 0.83-0.84, p < 0.001). The determination in vitro and/or prediction in silico of permeability coefficients across intestinal cell monolayers of a diverse range of industrial chems./food components/medicines could contribute to the safety evaluations of oral intakes of general chems. in humans. Such new alternative methods could also reduce the need for animal testing during toxicity assessment.
