In this paper, a series of 6-substituted-pyrido[3,2-e][1,2,4] triazolo[4,3-a] pyrazine derivatives have been synthesized. Their anticonvulsant activity and neurotoxicity in mice were evaluated by maximal electroshock (MES) and rotarod test, respectively. The structures were confirmed by H-1 NMR, C-13 NMR, MS and HRMS. The experimental results show that 6-phenoxypyrido[3,2-e][1,2,4] triazolo[4,3-a]pyrazine (5g) was safer than the reference drug, carbamazepine, with ED50 value of 93.9 mg.kg(-1) and protective index (PI) value of 24.3, which was a potential anti-epilepsy candidate compound.

Efforts to develop new antitumor agents are now directed towards multitarget therapies that are believed to have high potency and low tendency to resistance compared to conventional drugs. Herein, we highlighted the synthesis and antitumor activity of five series of phthalazine-based compounds featuring a variety of bioactive chemical fragments at position 1 of the phthalazine nucleus. The antitumor activity of the target compounds was performed against fourteen cancer cell lines where all compounds were active in the nanomolar level. In addition, the mechanism of action of the target compounds was investigated through an enzymatic inhibitory assay against VEGFR-2 and EGFR kinases, revealing potent and preferential activity toward VEGFR-2. Binding mode of the most active compounds was studied using docking experiment. (C) 2016 Elsevier Masson SAS. All rights reserved.

In a document, author is Qin, Peiyong, introduce the new discover, Quality Control of 2-Bromo-5-methoxybenzaldehyde.

In this study, propanedioic acid was investigated as a potential additive in poly(phthalazine ether sulfone ketone) (PPESK)/N-methyl-2-pyrrolidone solutions. Compared with poly(ethylene glycol) with a molecular weight of 1000 and Tween 80 as additives, different phenomena were observed: (1) both fingerlike and spongelike structures of asymmetric ultrafiltration membranes were induced by rapid gelation, and (2) a spongelike structure membrane with a high pure water flux was obtained under a high gelation rate. Moreover, the PPESK membrane formation process was recorded with a recently developed optical microscopy (OM)-charge-coupled device (CCD) camera experimental system. The predicted membrane structure with an OM-CCD system gave good correspondence with the final membrane structure and performance, as detected by scanning electron microscopy.

In a document, author is Bunce, Richard A., introduce the new discover.

Four phthalazine derivatives have been prepared from substituted 2-bromobenzaldehyde acetals by a sequence involving: (1) lithiation and formylation; (2) deprotection; and (3) condensative cyclization with hydrazine. Two additional phthalazines were prepared by a similar sequence following direct lithiation of benzaldehyde acetals substituted by anion-stabilizing groups at C3. These syntheses can be conveniently carried out to give phthalazines in overall yields of 40-70%.

In a document, author is Makarem, S., introduce the new discover, Product Details of 103-36-6.

Aza heterocyclic compounds are major interest for organic chemists because of their mainly pharmacological activities and clinical applications such as antianxiety, antitumor, anticonvulsant, cardiotonic and vasorelaxant. This contribution describes an electrochemical approach for the preparation of nanosized particles of phthalazine in high yields and very short reaction time. The method is based on the one-pot multicomponent reaction (MCRs) of phthalhydrazide, malononitrile and aldehydes in propanol employing undivided cell in the presence of NaBr as an electrolyte. The product was characterized, after purification, using IR, (HNMR)-H-1, C-13 NMR, MS and SEM. This procedure provides a method by which nanoparticles are synthesized directly from phthalhydrazide, malononitrile and aldehydes insides of a routine protocol for the synthesis of nano particles of organic compounds in which the synthesized organic compound is transformed into nanosized particles using modem high technology, for example ultrahighpressure rapid expansion of supercritical solution, and supercritical antisolvent with enhanced mass transfer. Size reduction is a fundamental unit operation having important applications in pharmacy. It helps to improve solubility and bioavailability, reduce toxicity, enhance release, and provide better formulation opportunities for drugs.

In a document, author is Musa, Ahmed Y., introduce the new discover, Electric Literature of 1821-12-1.

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.

Category: phthalazines, Reactions catalyzed within inorganic and organic materials and at electrochemical interfaces commonly occur at high coverage and in condensed media, causing turnover rates to depend strongly on interfacial structure and composition. 92-92-2, Name is [1,1′-Biphenyl]-4-carboxylic acid, SMILES is O=C(C1=CC=C(C2=CC=CC=C2)C=C1)O, belongs to phthalazine compound. In a article, author is Rastogi, Shiva K., introduce new discover of the category.

Two protocols for oxygenation of aromatic C-H bonds ortho-positioned to the phthalazine ring were developed. The transannulation of the phthalazine ring to a naphthalene moiety by an Inverse Electron Demand Diels-Alder (IEDDA) reaction led to the synthesis of naphtho[2,1-c]chromenes, 1-(ortho-hydroxyaryl)naphthalenes and 6,7-dihydrobenzo[b]naphtho[1,2-d]oxepine. This new strategy based on the utilization of transformable nitrogen heterocycles in C-H functionalization chemistry can be potentially applicable to the synthesis of a broad range of biaryl compounds.
