Now introduce a scientific discovery about this category, Quality Control of Triphenylsilane.

In this research, we report a novel synthesis of magnetic beta-alanine-functionalized-graphene oxide quantum dots Fe3O4@GOQDs-N-(beta-alanine) as a recyclable and eco-friendly heterogeneous nanocatalyst. The catalytic efficiency of these nanosheets was explored as a basic catalyst for a one-pot three-component synthesis of various 1H-pyrazolo[1,2-b]phthalazine-5,10-dione and 2,3-dihydroquinazolin-4(1H)-one derivatives. The reactions proceeded smoothly under mild and green conditions to afford the respected products in excellent yields. The structure of this newly fabricated catalyst was successfully confirmed by different analytical techniques such as Fourier transform infrared spectroscopy, X-ray diffraction, field emission-scanning electron microscopy, high-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, vibrating sample magnetometry, and thermogravimetric analysis. The stability and recyclability of the catalyst were examined by performing the model reaction in six consecutive runs. The recovered catalyst from the first run was directly used for the next runs with no significant loss of catalytic activity.

Biocomposite nanomaterials have been evolved as the new generation catalysts and therapeutic supplement in these days. Magnetically isolation has added new features to this category. This has encouraged us to synthesize a novel Ag NP adorned chitosan-alginate dual bio-polysaccharide (two of the more versatile polysaccharides) modified core-shell magnetic nanocomposite (Fe3O4/CS-Alg/Ag NPs). The material was meticulously characterized following different physicochemical techniques, such as, FT-IR, ICP-OES, FESEM, EDX, atomic mapping, TEM, VSM, XRD and XPS studies. The as synthesized material was catalytically explored in the one-pot multicomponent synthesis of biologically potent 2H-indazolo[2,1-b]phthalazine-trione derivatives involving a wide range of substrates. The reactions were ended up with excellent yields under solvent-free heating conditions. The catalyst recyclability, heterogeneity and leaching tests were performed to ensure its high stability and robustness. It could be reused as much as 10 times in succession with almost unchanged catalytic performances. In the lung protective part of the present research, the human lung toxicity was induced by alpha-Guttiferin. The cell viability of lung MRC-5, CCD-19Lu, WI-38, and BEAS-2B cell lines was measured by trypan blue assay. Caspase-3 activity was assessed by the caspase activity colorimetric assay kit and mitochondrial membrane potential of lung cells was studied by Rhodamine123 fluorescence dye. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) test was used to show DNA fragmentation and apoptosis of lung cells. Also, the Rat inflammatory cytokine assay kit was used to measure the concentrations of inflammatory cytokines. The catalyst-treated cell cutlers significantly (p <= 0.01) reduced the DNA fragmentation, caspase-3 activity, and inflammatory cytokines concentrations, and raised the mitochondrial membrane potential and cell viability in the high concentration of alpha-Guttiferin-treated lung MRC-5, CCD-19Lu, WI-38, and BEAS-2B cells. The best result of lung protective properties of catalyst against alpha-Guttiferin was seen in the high dose of catalyst i.e., 4 mu g. DPPH test revealed similar antioxidant potentials for catalyst and butylated hydroxytoluene. The catalyst inhibited half of the DPPH molecules in the concentration of 171 mu g/mL. According to the above results, catalyst can be administrated as a lung protective drug for the treatment of lung diseases after approving in the clinical trial studies in humans.

A new series of 2-substituted-2,3-dihydrophthalazine-1,4-diones (2 9) were designed and synthesized to evaluate their anticonvulsant activity. The neurotoxicity was assessed using the rotarod test. Molecular docking was performed for the synthesized compounds to assess their binding affinities as -aminobutyric acid A (GABA-A) receptor agonists as a possible mechanism of their anticonvulsant action, to rationalize their anticonvulsant activity in a qualitative way. The data obtained from the molecular modeling was strongly matched with that obtained from the biological screening, which revealed that compounds 5(a), 9(b), and 9(h) showed the highest binding affinities toward the GABA-A receptor and also showed the highest anticonvulsant activities with relative potencies of 1.66, 1.63, and 1.61, respectively, compared with diazepam. The most active compounds 5(a), 9(b), and 9(h) were further tested against maximal electroshock seizures. Compounds 5(a) and 9(b) showed 100% protection at a dose level of 125 mu g/kg, while compound 9(h) exhibited 83.33% protection at the same dose level. A GABA enzymatic assay was performed for these highly active compounds to confirm the obtained results and to explain the possible mechanism for their anticonvulsant action. These agents exerted low neurotoxicity and a high safety margin compared with valproate as a reference drug. Most of our designed compounds exhibited a good ADMET profile.

The abilities of phthalazine derivatives, including phthalazine (PT), phthalazone (PTO) and phthalhydrazide (PTD), to inhibit the corrosion of mild steel in 1 M HCl at 30 degrees C were studied using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization measurements. Theoretical calculations were performed to investigate the electronic structures of the PT derivatives. Our results showed that the inhibition efficiencies of these derivatives improved with increases in concentration. The data also showed that PTD < PT < PTO in terms of the inhibiting efficiency. Theoretical calculations also revealed that PTO is expected to be the best inhibitor among the studied phthalazine derivatives. (C) 2011 Elsevier Ltd. All rights reserved.

High-performance pure near-infrared organic light-emitting materials and devices with full emission over 700 nm are still rare, though urgently needed. Iridium(iii) complexes have been proven to be an important class of NIR emitters. Herein, we report a new NIR homoleptic Ir(iii) complex, tris[1,4-di(5-n-octylthiophen-2-yl)benzo[g]phthalazine] iridium(iii) (Ir(dotbpa)(3)), with full emission beyond 700 nm with an iridium mass content as low as 10 wt%. Thanks to the introduction of flexiblen-octyl groups,Ir(dotbpa)(3)shows greatly improved solubility and excellent solution-processability in comparison with its counterpartIr(dtbpa)(3). By utilizing a multifunctional host, solution-processed NIR-OLEDs were fabricated with a simple structure of only three organic layers and they demonstrated a pure NIR emission starting from 725 nm and a peak at 850 nm with the maximum external quantum efficiency of 0.17%, which makes them the first example of pure NIR-OLEDs based on Ir(iii) emitters.
