In this paper, we adopt a facile method to prepare a type of porous silica nanoparticles (n-SiO2) from tetraethyl orthosilicate as the source of silica. Then, dendritic polymer supported on nanosilica with surface amino groups was fabricated. Finally, H3PW12O40 nanoparticles (PWA(n)) were synthesized by the treatment of H3PW12O40 powder with n-Octane as solvent by a solvothermal method and then immobilized onto the dendrimer polymer functionalized nanosilica. The synthesized nanostructures were characterized by fourier transform infrared (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), dynamic light scattering (DLS), N-2 adsorption-desorption isotherm analysis, UV-Vis and elemental analysis. The morphology of the catalyst was characterized using transmission electron microscopes (TEM). The acidity of the catalyst was determined by FTIR pyridine adsorption spectroscopy. Then, this catalytic system was used as an efficient catalyst for the synthesis of 2H-indazolo[2,1-b]phthalazine-triones via multi-component and one-pot reactions of various aldehydes, phthalic anhydride, hydrazinium hydroxide, and dimedone under thermal solvent-free conditions or ultrasound irradiation at room temperature. Also, the catalyst can be easily recovered and reused for six consecutive reaction cycles without significant loss of activity.

The purification and reclaiming of synthetic and industrial high temperature condensed water containing excess oil and iron is investigated in this study using thermostable poly(phthalazine ether sulfone ketone) (PPESK) ultrafiltration membranes. The results show operation parameters such as transmembrane pressure, temperature and pH of feed solution, initial oil and iron concentration each play important roles in the permeate flux and oil/iron removal efficiencies. Membrane performance is almost recovered after washing with a combination of NaOH and ethanol. High temperature condensed water from Daqing petroleum refinery can be consecutively purified using a PPESK ultrafiltration membrane. The turbidity of the solutions is almost removed. Oil and iron concentrations in the permeate solutions are below 1 mg/L and 50 mu g/L, respectively, which satisfy the Quality Criterion of Water and Steam for Steam Power Equipment in China. UF process shows a promising alternative to existing technology in the Daqing petroleum refinery in terms of cost and environmental protection as well as energy recovery. For future possible combination of UF and NF process application, both economic cost and saving are evaluated, and the breakeven time is about 11 months. (C) 2013 Elsevier B.V. All rights reserved.

Aldehyde oxidase (AOX) is a cytosolic enzyme expressed across a wide range of species, including guinea pig and rhesus monkey. These species are believed to be the best preclinical models for studying human AOX-mediated metabolism. We compared AOX activity in rhesus monkeys, guinea pigs, and humans using phthalazine and N-[2-(dimethylamino) ethyl] acridone-4-carboxamide (DACA) as substrates and raloxifene as an inhibitor. Michaelis-Menten kinetics was observed for phthalazine oxidation in rhesus monkey, guinea pig, and human liver cytosol, whereas substrate inhibition was seen with DACA oxidase activity in all three livers. Raloxifene inhibited phthalazine and DACA oxidase activity uncompetitively in guinea pig, whereas mixed-mode inhibition was seen in rhesus monkey. Our analysis of the primary sequence alignment of rhesus monkey, guinea pig, and human aldehyde oxidase isoform 1 (AOX1) along with homology modeling has led to the identification of several amino acid residue differences within the active site and substrate entrance channel of AOX1. We speculate that some of these residues might be responsible for the differences observed in activity. Overall, our data indicate that rhesus monkeys and guinea pigs would overestimate intrinsic clearance in humans and would be unsuitable to use as animal models. Our study also showed that AOX metabolism in species is substrate-dependent and no single animal model can be reliably used to predict every drug response in humans.

Common marmosets (Callithrix jacchus), New World monkeys, are a promising primate model for preclinical drug metabolism studies because of the similarities of cytochrome P450 (P450) enzyme function to those of humans. Despite an increasing number of drug candidates catalyzed by non-P450 enzymes, drug metabolizing enzymes other than P450s have been hardly identified or characterized in marmosets. In this study, we identified aldehyde oxidase (AOX) 1 gene by marmoset genome analysis. AOX1 cDNA was cloned from marmoset livers by reverse transcription-polymerase chain reaction. Deduced amino acid sequences of AOX1 cDNA showed high sequence identities (92-93%) with primate AOX1s. Phylogenetic analysis showed that marmoset AOX1 was closely clustered with primate AOX1s, unlike nonprimate animal model AOX1s of pig, rabbit, rat, and mouse used in drug metabolism. The tissue expression analyses by real-time reverse-transcription polymerase chain reaction and immunoblotting showed that marmoset AOX1 mRNA and protein were abundantly expressed in livers, similar to cynomolgus monkeys and humans. Marmoset AOX1 heterologously expressed in Escherichia coli catalyzed the oxidation of carbazeran and phthalazine, typical AOX1 substrates, similar to cynomolgus monkey and human AOX1s. Human and marmoset AOX1 effectively catalyzed phthalazine oxidation when assessed with Michaelis-Menten kinetics, but cynomolgus monkey AOX1 catalyzed this reaction with cooperative kinetics with high capacity. These results indicated that tissue distribution and enzymatic function of AOX1 enzyme is similar between marmosets and humans, suggesting that marmosets are a suitable primate model for AOXdependent drug metabolism in preclinical studies.

Cost-effective fabrication of white organic light-emitting diodes (WOLED) is meaningful toward commercial application of environment-friendly solid-state lighting sources. Electroluminescent efficiency and color quality are two opposite performance characteristics facing solution processed WOLEDs requiring balanced consideration. Herein, a recently synthesized molecule of 4,4′-(9,9′-(1,3-phenylene) bis(9H-fluorene-9,9-diyl)) bis(N,N-diphenylaniline) (DTPAFB) is introduced as a host material for solution processed all-phosphor WOLEDs, embracing four well-known molecules which are blue iridium (III) bis(2-(4,6-difluorophenyl) pyridinato-N,C-2)(picolinate) (FIrpic), green iridium (III) bis[2-(2-pyridinyl-N) phenyl-C](2,4-pentanedionato-O-2,O-4)[Ir(ppy)(2)(acac)], and orange iridium (III) bis(2-phenyl-benzothiazole-C-2, N)(acetylacetonate) [Ir(bt)(2)(acac)] plus a home-made red phosphor of iridium (III) tris(1-(2,6dimethylphenoxy)-4-(4-chlorophenyl) phthalazine) [Ir(MPCPPZ)(3)]. Illumination quality white light with high brightness, high efficiency, suitable correlated color temperature (CCT), high color-rendering index (CRI), and stable electroluminescent (EL) emission is obtained. A stable white emission with a CRI over 70, Commission Internationale de L’Eclairage (CIE) of (0.37, 0.42), and high EL efficiency of 19.6 lm W-1 at high luminance of 2000 cd m(-2) for blue/orange complementary color WOLEDs is demonstrated. The optimized red/green/blue three primary color WOLEDs show improved CRI up to 81, moderate high efficiency of 25.8 cd A(-1), 14.4 lm W-1, and EQE of 13.9%. Furthermore, the red/green/blue/orange four primary color WOLEDs show the optional balance between color quality and EL efficiency with high CRI of around 81-83 and medium CCT of 3755-3929 K which is warm and soft to human eyes. At an illumination relevant luminance of 1000 cd m(-2), the total power efficiency reaches 33.6 lmW(-1), and still remains 30.2 lm W-1 at 3000 cd m(-2), approaching the efficiency of state-of-the-art fluorescent-tube (40 – 70 lm W-1), potentially suitable as an environment-friendly solid-state lighting source. This work indicates that developing high performance host materials and highly efficient phosphors and carefully combining them with common phosphors is an effective way toward high performance WOLEDs.

Searching for new leads in the battle of cancer will never ends, we herein disclose the design and synthesis of new phthalazine derivatives and their in vitro and in vivo testing for their antiproliferative activity. Phthalazine was selected as a privilege moiety that is incorporated in a big number of anticancer drugs in clinical use or that are still under clinical or preclinical studies. We utilized the drug extension strategy to tailor the designed compounds to fit the EGFR hydrophobic sub pocket and cleft region. The designed phthalazine derivatives was synthesized by linking phthalazine moiety with 1,3,4-oxadiazole-thione and 1,2,4-triazole-thione. Alkylation and glycosylation of the new heterocyclic systems were successfully performed to be used in the drug extension. Coupling of some phthalazine derivatives with different amino acids was also performed to improve the drug selectivity. The synthesized compounds were tested for their antiproliferative activity against cancer cells both in vivo and in vitro. The in vitro activity against hepatocellular carcinoma (HepG2 cell line) ranged from 5.7 mu g/mL to 43.4 mu g/mL. Compounds 31a and 16 were the most active with an IC(50)5.7 mu g/mL and 7.09 mu g/mL, respectively compared to the standard compound doxorubicin (4.0 mu g/mL). In vivo, compounds 10 and 16 showed IC50 values 7.25 mu g/mL and 7.5 mu g/mL, respectively compared to the standard compound cisplatin (IC50, 9.0 mu g/mL). In silico, testing of the phthalazine derivatives showed that they are good inhibitors for EGFR. The docking studies substantiated compounds 4, 10, 16 and 31a as new lead compounds and identified Arg841 as a key residue in the cleft region for binding stronger inhibitors.

We report herein the design and synthesis of a series of optimized phthalazine compounds as novel hedgehog signaling pathway inhibitors. The 4-methylamino-piperidine moiety of Taladegib was replaced by different four, five or six-membered azacycle or azaspirocycle building blocks. The in vitro Gliluciferase assay results demonstrate that the scaffold hopping in this region afforded significant influences on Hh pathway inhibition. Pyrrolidin-3-amine moiety was found to be the best linker between pharmacophores phthalazine and fluorine substituted benzoyl group. Meanwhile the optimization of 1-methyl-1H-pyrazol by different aromatic rings was also investigated and the SAR was described. Many new derivatives were found to show potent Hh signaling inhibitory activity with nanomolar IC50 values. Among these compounds, compound 23b showed the highest inhibitory potency with an IC50 value of 0.17 nM, which was 35-fold more potent than the lead compound Taladegib and 23-fold more potent than the marketed drug Vismodegib. The selected compounds 23a and 23b also possess potent antitumor activities against medulloblastoma cells proliferation in vitro. In vivo efficacy of 23b in a ptch(+/-)p53(-/-) mouse medulloblastoma allograft model also indicated encouraging results. (C) 2017 Elsevier Masson SAS. All rights reserved.
