Organo-Sulfonic acid tags anchored on magnetic titana coated NiFe2O4 nanoparticles (nano-NiFe2O4@TiO2-SiO2-Pr-DEA-OSO3H) was prepared and characterized by various analysis methods including Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), vibrating sample magnetometer (VSM), X-ray diffraction (XRD) and thermo gravimetric analysis (TGA). These modified nanoparticles were used as efficient and recoverable hybrid nanocatalyst in multicomponent synthesis of some phthalazine-trione and benzo[4,5]imidazo[1,2-a]pyrimidine derivatives under green conditions. High yields within shorter reaction times, simple purification, and environmentally mild reaction conditions are some advantages of this protocol.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 5267-64-1 is helpful to your research. Quality Control of D-Penylalaninol.

In a document, author is Machura, B..

The paper presents a combined experimental and computational study for three oxalate copper(II) complexes [Cu(ptz)(2)(C2O4)(H2O)center dot 1.5H(2)O (1), [Cu(dppt)(C2O4)(H2O)]center dot H2O.MeOH (2) and [Cu(dmdpq)(C2O4)(- H2O)]center dot 5H(2)O (3) (ptz = phthalazine, dppt = 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine and dmdpq = 6,7-dimethyl-2,3-di(2-pyridyl)quinoxaline). The compounds have been studied by IR, UV-Vis spectroscopy and single crystal X-ray analysis. Due to the presence of coordinated water molecules and oxalate groups together with the lattice solvent molecules (water and methanol) their crystal structures are dominated by the hydrogen-bonding interactions that give rise to the supramolecular architectures. To elucidate the structural and spectroscopic properties of[Cu(ptz)(2)(C2O4)(H2O)], [Cu(dppt)(C2O4)(H2O)] and [Cu(dmdpq)(C2O4)(H2O)], calculations at DFT, TDDFT level were undertaken. Magnetic studies of all complexes under study showed paramagnetic behavior with large orbital magnetic contribution. (c) 2013 Elsevier Ltd. All rights reserved.

The synthesis, structure, and in vitro anticancer activity of a new class of anticancer derivatives with dihydrobenzo[5,6]isoindolo[1,2-a]phthalazine and dihydrobenzo[f]pyridazino[6,1-a]isoindole skeletons are presented. The preparation is straight and efficient, involving two steps only: a N-alkylation of the pyridazine or phthalazine heterocycle, followed by a [3 + 2] dipolar cycloaddition of 1,2-diazinium ylides to the corresponding dipolarophiles. The synthesis was performed under microwave and ultrasound (US) irradiation as well as under conventional thermal heating. The most effective conditions in term of yields and time were found to be US irradiation. The penta- and tetra-cyclic 1,2-diazines were evaluated for their in vitro anticancer activity. The pentacyclic 1,2-diazine derivatives exhibit a significant anticancer activity against Non-Small Cell Lung Cancer NCI-H460, Leukemia MOLT-4, Leukemia CCRF-CEM, and Breast Cancer MCF7. A feasible explanation for anticancer efficiency of the pentacyclic 1,2-diazines have been furnished, being correlated with the mechanisms of action. The synthesis (conventional thermal heating, microwave and ultrasound irradiation), structure, and in vitro anticancer activity of a new class of anticancer molecules with polycyclic 1,2-diazines skeleton is presented.

Aldehyde oxidase (AOX) is a xanthine oxidase (XO)-related enzyme with emerging importance due to its role in the metabolism of drugs and xenobiotics. We report the first crystal structures of human AOX1, substrate free (2.6-angstrom resolution) and in complex with the substrate phthalazine and the inhibitor thioridazine (2.7-angstrom resolution). Analysis of the protein active site combined with steady-state kinetic studies highlight the unique features, including binding and substrate orientation at the active site, that characterize human AOX1 as an important drug-metabolizing enzyme. Structural analysis of the complex with the noncompetitive inhibitor thioridazine revealed a new, unexpected and fully occupied inhibitor-binding site that is structurally conserved among mammalian AOXs and XO. The new structural insights into the catalytic and inhibition mechanisms of human AOX that we now report will be of great value for the rational analysis of clinical drug interactions involving inhibition of AOX1 and for the prediction and design of AOX-stable putative drugs.

In a article, author is Turkes, Cuneyt, introduce new discover of the category.

The synthesis, characterization and biological evaluation of a series of novel N-substituted phthalazine sulfonamide (5a-1) are disclosed. Phthalazines which are nitrogen-containing heterocyclic compounds are biologically preferential scaffolds, endowed with versatile pharmacological activity, such as anti-inflammatory, cardiotonic vasorelaxant, anticonvulsant, antihypertensive, antibacterial, anti-cancer action. The compounds were investigated for the inhibition against the cytosolic hCA I, II and AChE. Most screened sulfonamides showed high potency in inhibiting hCA II, widely involved in glaucoma, epilepsy, edema, and other pathologies (K(i)s in the ranging from 6.32 +/- 0.06 to 128.93 +/- 23.11 nM). hCA I was inhibited with K(i)s in the range of 6.80 +/- 0.10-85.91 +/- 7.57 nM, whereas AChE in the range of 60.79 +/- 3.51-249.55 +/- 7.89 nM. ADME prediction study of the designed N-substituted phthalazine sulfonamides showed that they are not only with carbonic anhydrase and acetylcholinesterase inhibitory activities but also with appropriate pharmacokinetic, physicochemical parameters and drug-likeness properties. Also, in silico docking studies were investigated the binding modes of selected compounds, to hCA I, II, and AChE.

SDS of cas: 66-99-9, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. 66-99-9, Name is 2-Naphthaldehyde, SMILES is O=CC1=CC=C2C=CC=CC2=C1, belongs to phthalazine compound. In a article, author is Glisic, Biljana D., introduce new discover of the category.

Five copper(II) complexes 1-5 with aromatic nitrogen-containing heterocycles, pyrimidine (pm, 1), pyrazine (pz, 2), quinazoline (qz, 3 and 4) and phthalazine (phtz, 5) have been synthesized and structurally characterized by spectroscopic and single-crystal X-ray diffraction techniques. The crystallographic results show that, dependent on the ligand structure, complexes 1-5 are of different nuclearity. The antimicrobial efficiency of complexes 1-5 has been evaluated against three clinically relevant microorganisms and none of the complexes showed significant growth inhibiting activity, with values of minimum inhibitory concentrations (MIC) in the mM range. Since in many bacteria, pathogenicity and virulence are regulated by intercellular communication processes, quorum sensing (QS), the effect of the copper(II) complexes on bacterial QS has also been examined. The results indicate that the investigated complexes inhibit violacein production in Chromobacterium violaceum CV026, suggesting an anti-QS activity. In order to differentiate, which of the QS pathways was affected by the copper(II) complexes, three biosensor strains were used: the PAO1 Delta rhlIpKD-rhlA and the PA14-R3 Delta lasIPrsaI lux strain to directly measure the levels of C4-HSL (N-butanoyl-homoserine lactone) and 3OC12-HSL (N-3-oxo-dodecanoyl- homoserine lactone), respectively, and PAO1 Delta pqsA mini-CTX luxPpqsA for the detection of AHQs (2-alkyl-4-quinolones). Complexes 1-5 were shown to be efficient inhibitors of biofilm formation of the human opportunistic pathogen Pseudomonas aeruginosa PAO1, with the qz-containing complex 3 being the most active. Finally, the most anti-QS-active complexes 1 and 3 showed synergistic activity against a multi-drug resistant clinical isolate of P. aeruginosa, when supplied in combination with the known antibiotics piperacillin and ceftazidime.
