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.

A new protocol for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives is described via a one-pot three-component condensation reaction of phthalhydrazide, dimedone or 1,3-cyclohexanedione and aromatic aldehydes catalyzed by SnO2 nanoparticles as a heterogeneous catalyst under solvent-free conditions. The SnO2 nanoparticles (NPs) were characterized by FT-IR, X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and energy dispersive X-ray analyzer (EDAX). The advantages of the protocol are the shorter reaction time, simple work-up procedure and reusable catalyst. [GRAPHICS] .

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, and theoretical assessments of solvent structures and their interactions with reaction intermediates and transition states. 5267-64-1, Name is D-Penylalaninol, molecular formula is C9H13NO, belongs to phthalazine compound. In a document, author is Glisic, Biljana D., introduce the new discover, Related Products of 5267-64-1.

A series of mononuclear gold(iii) complexes of the general formula [AuCl3(diazanaphthalene)], where diazanaphthalene is quinazoline (qz, 1), phthalazine (phtz, 2), 1,5-naphthyridine (1,5-naph, 3), 1,6-naphthyridine (1,6-naph, 4) or 1,8-naphthyridine (1,8-naph, 5), were prepared and fully characterized. The complexes 1-5 consist of discrete monomeric species with the Au(iii) cation in a square planar coordination geometry surrounded by three chloride anions and one diazanaphthalene ligand. Crystallographic studies indicate the presence of an extended 4 + 1 or 4 + 2 geometry around the square planar [AuCl3(diazanaphthalene)] center due to AuMIDLINE HORIZONTAL ELLIPSISCl and AuMIDLINE HORIZONTAL ELLIPSISN interactions. The crystal structures of these complexes are controlled by a variety of intermolecular interactions that utilize the amphiphilic properties of the coordinated chloride anions and involve C-H groups, pi-electrons, and an uncoordinated nitrogen atom of the diazanaphthalene ligand. The usual offset pi-stacking between the N-heteroaromatic ligands appears to be completely hindered between the 1,5-naph fragments and significantly weakened between the 1,6-naph and 1,8-naph in their respective complexes 3, 4 and 5, for which the average molecular polarizability (alpha) values are the lowest in the series. It is remarkable that the [AuCl3(benzodiazine)] complexes 1 and 2 form centrosymmetric crystals, but the [AuCl3(naphthyridine)] complexes 3-5 assemble into non-centrosymmetric aggregates, making them potential alternatives to the previously studied systems for application in various fields by taking advantage of their polarity.

Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 83-38-5, Name is 2,6-Dichlorobenzaldehyde, molecular formula is , belongs to phthalazine compound. In a document, author is Yu, Hai-Ling, Category: phthalazines.

Thrombosis is a major complication that could be fatal in acute or chronic cardio-cerebral-vascular diseases. Therefore, the development of novel agents for anticlotting and the prevention of thrombosis and cardiovascular diseases are clinically significant. This study aimed to evaluate the anticoagulant and antithrombotic effects of 6-(4-chlorophenoxy)-tetrazolo[5,1-a]phthalazine (Q808), a new phthalazine tetrazole derivative. Bleeding time, clotting time, and serum calcium ion (Ca2+) concentration were assessed in mice, whereas arteriovenous thrombus weight and plasma prothrombin time were evaluated in rats, and platelets Ca2+ influx was determined in rabbit. Daily oral administration of Q808 at 25, 50, or 100 mg/kg for 3 days significantly delayed bleeding time and clotting time in mice compared with controls. Q808 administration at 50 mg/kg significantly reduced experimental thrombus weight by 62.6% and delayed plasma prothrombin time by 58.7% in rats, whereas 50 and 100 mg/kg of Q808 daily significantly increased serum Ca2+ concentration in mice. Q808 at 0.2, 0.4, and 0.8 mg/mL significantly inhibited thrombin-induced Ca2+ influx in rabbit platelets. Our results suggest that Q808 at 25-200 mg/kg daily exerts anticoagulant and antithrombotic effects, and its mechanisms of action may involve both the intrinsic and extrinsic coagulation pathways that inhibit certain coagulation factors and platelet functions.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 83-38-5 help many people in the next few years. Category: phthalazines.

Phosphoramidates are for the first time presented as efficient N-Centered Radical (NCR) precursors under visible-light irradiation. More precisely among this class of phosphorus-derived compounds, we studied the radical reactivity of phosphonohydrazones, under mild reaction conditions, which allowed the synthesis of a wide and diversified library of the scarcely reported phthalazine scaffold. Mechanistic investigations confirmed the formation of a NCR from these brand-new phosphonohydrazones (derivatived from phosphoramidates), which were further engaged in an intramolecular 6-exo-dig cyclization to provide phthalazines. Compared to other pre-activated moieties, the phosphoramidate group is self-immolative, thus enhancing its attractiveness for the C-N bond formation.
