This paper reports an evaluation of the effect of both organic and inorganic additives on the gelation kinetics, morphology and separation properties of asymmetric poly(phthalazine ether ketone) (PPEK) hollow fiber ultrafiltration membranes. Using an online optical microscope-CCD camera for observation of precipitation front movement (X), a good linear relationship between X-2 and time was observed for the whole gelation process with the correlation coefficient (R-2) higher than 0.98. It was found that the pure water flux of membranes with additives were lower than neat PPEK membranes. This observation might be attributed to the decrease in the face gelation velocity caused by the extra organic additives. The water flux of PEG600 was higher than that of Tween80 at the same additive concentration. When OA concentration increased from 3.5 to 5.0 wt.%, the pure water flux increased from 332 to 367 L/m(2) hand the rejection decreased from 98.6 to 96.8%. The PPEK hollow fiber membranes exhibited finger-like macrovoids structure and a skin layer at the outer-most region of the hollow fiber. Evaluation of the membrane chemical resistance with various chemical solutions indicated that PPEK membranes had good chemical resistance against HCI, H2SO4, HNO3, CH3COOH, OA, NaOH and H2O2, while the NaClO solution can greatly damage the membrane mechanical strength. Static sorption tests of PPEK membrane revealed that PPEK membrane adsorbed more bacitracin than BSA due to the smaller size of bacitracin. (C) 2011 Elsevier B.V. All rights reserved.

Multifunction luminogens have emerged as promising candidates in high-performance sensor and imaging systems. Concise approaches to the synthesis of such molecules are urgently required both for fundamental research and technological applications. In this study, a new symmetric ligand of di(2-hydroxyphenyl)phthalazine with multiple binding sites around a phthalazine unit was readily synthesized, which could be converted efficiently into an asymmetric luminogen (OBNDHPP) through the formation of oxygen-boron-nitrogen bonding. This molecule has a twistable it-extended backbone with a tetracoordinated boron core bearing two bulky phenyl groups, giving it abundant optical properties including a large Stokes shift piezochromism and aggregationinduced emission enhancement. Importantly, the presence of a free phenolic hydroxyl group in the backbone of OBN-DHPP enables the incorporation of various functional moieties into the asymmetric luminogen. As an example, polyethylene glycol (PEG)-modified luminogen (OBN-DHPP-PEG(45)) was synthesized. In the aqueous medium, OBN-DHPP-PEG(45) could self-assemble into spherical nanoparticles with low cytotoxicity and excellent emission performance as well as high solubility. The results of flow cytometry and fluorescence microscopy reveal that these nanoparticles could be internalized successfully by HeLa cells, demonstrating their potential application in bioimaging.

Name: H-Glu(OBzl)-OH, In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 1676-73-9, Name is H-Glu(OBzl)-OH, SMILES is N[C@@H](CCC(OCC1=CC=CC=C1)=O)C(O)=O, belongs to phthalazine compound. In a article, author is Fan, Mingxuan, introduce new discover of the category.

In this paper, two pyridazine-heterocycles-containing azaacenes 9,12-diphenylphenanthro[4,5-fgh]phthalazine (DPPA) and 2,9-di-tert-butyl-4,7,11,14-tetraphenylpyridazino[4′,5′:9,10] phenanthro[4,5-fgh]phthalazine (TPPA) have been synthesized and fully characterized. The single crystal analysis of TPPA showed that TPPA molecule exhibits a twisted structure with the dihedral angel of 27 degrees between pyrene and pyridazine unit, which suppresses the pi-pi stackings in the solid state. The two-photon absorption properties of DPPA and TPPA were investigated, respectively, by using the femtosecond Z-scan technique. The results showed that both DPPA and TPPA showed moderate two-photon absorption cross-section values, and the larger one was found to be 454 GM with TPPA. Obviously, the introduction of pyridazine ring into the skeleton of acenes forming a A-D-A structure could lead to a much larger two-photon absorption coefficient and two-photon absorption cross section.

Alumination of Si-KIT-6 materials with ordered three-dimensional (3D) structure were prepared by post-synthesis method with various Si/Al ratios. The catalysts were characterized by X-ray diffraction analysis (XRD), N-2 porosimetry and FT-IR spectra. The presence of framework and extra framework aluminium was predicted by Aluminium MAS NMR. The strength of the acid sites of the catalysts was studied by NH3-TPD acidity measurements. The morphology of mesoporous materials was studied by SEM and TEM observation. The metal content of the samples was investigated by ICP-OES. The prepared solid acid catalysts were applied for the multi-component synthesis of 1H-pyrazolo[1,2-]phthalazine-5,10-diones from the reaction of phthalhydrazide, malononitrile/ethylcyano acetate and aromatic aldehyde in ethanol under liquid phase conditions.

Chemistry, like all the natural sciences, Safety of H-Glu(OBzl)-OH, begins with the direct observation of nature— in this case, of matter.1676-73-9, Name is H-Glu(OBzl)-OH, SMILES is N[C@@H](CCC(OCC1=CC=CC=C1)=O)C(O)=O, belongs to phthalazine compound. In a document, author is Olmo, Francisco, introduce the new discover.

A series of new phthalazine derivatives (1-4) containing imidazole rings and functionalized with nitro groups in the benzene ring of the phthalazine moiety were prepared and identified on the basis of their MS, elemental analyses and bidimensional H-1 and C-13 NMR data, and their trypanocidal activity was tested. The 8-nitrosubstituted compound (3) was more active in vitro against Trypanosoma cruzi and less toxic against Vero cells than the reference drug benznidazole, and showed a SI value that was 47-fold better than the reference drug in amastigote forms. It also remarkably reduced the infectivity rate in Vero cells and decreased the reactivation of parasitemia in immunodeficient mice. Ultrastructural alterations found in epimastigotes treated with 3 confirmed extensive cytoplasm destruction in the parasites, whereas histopathological analysis of the hearts of mice infected and treated with 3 resulted in a decrease in cardiac damage. Biochemical markers showed that livers, hearts, and kidneys of treated mice were substantially unaffected by the administration of 3, despite the presence of the potentially toxic nitro group. It was also found that this compound selectively inhibited the antioxidant parasite enzyme Fe-superoxide dismutase (Fe-SOD) in comparison with human CuZn-SOD, and molecular modeling suggested interaction with the H-bonding system of the iron-based moiety as a feasible mechanism of action against the enzyme.

Various pyridopyridazinone derivatives were designed as Poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors. The pyridopyridazinone scaffold was used as an isostere of the phthalazine nucleus of the lead compound Olaparib in addition to some modifications in the tail part of the molecule. Preliminary biological evaluation indicated that most compounds possessed inhibitory potencies comparable to Olaparib in nanomolar level. The best PARP-1 inhibitory activity was observed for compound 8a with (IC50 = 36 nM) compared to Olaparib as a reference drug (IC50 = 34 nM). Molecular modeling simulation revealed that, the designed compounds docked well into PARP-1 active site and their complexes are stabilized by three key hydrogen bond interactions with both Gly863 and Ser904 as well as other favorable pi-pi and hydrogen-pi stacking interactions with Tyr907 and Tyr896, respectively. Computational ADME study predicted that the target compounds 8a and 8e have proper pharmacokinetic and drug-likeness properties. These outcomes afford a new structural framework for the design of novel inhibitors for PARP-1.
