Dibenzobarallene was used as a key intermediate for the synthesis of 2-(3-hydroxy-2-naphthoyl)-3,4,4a, 5,10,10a-hexahydro-1H-5,10-benzenobenzo[g]phthalazine-1,4-dione (2). The previous compound was coupled with the appropriate diazonium chloride to give the corresponding 4-arylazo-2-naphthol derivatives 3a-l. Also, nitration, nitrosation and bromination of compound 2 afforded the corresponding nitro, nitroso and bromo derivatives 4-6, respectively. The synthesized compounds were established and evaluated as antibacterial agents. The results showed clearly that compounds 2, 3a, 3c, 3d, 3g, 3i, 4, 5 and 6 exhibited interesting high activities compared with reference drugs. Also, these compounds were applied to polyester as disperse dyes in which their color measurement and fastness properties were evaluated.

A direct carbocyclization of 2-aryl-2,3-dihydrophthalazine-1,4-diones is achieved using isocyanates as carbonyl source via Ru(II)-catalyzed sequential ortho-amidation followed by intramolecular nucleophilic substitution, delivering substituted indazolo[1,2-b]phthalazine-triones in good-to-excellent yields. For ortho-substituted 2-aryl-2,3-dihydrophthalazine-1,4-diones, the corresponding amidated products were also isolated in excellent yields by modifying the reaction parameters. Application of isocyanates as carbonyl source, high functional group tolerance on the two coupling partners and diverse chemical transformation of the synthesized fused and functionalized phthalazinones are the key highlights of the work.

SDS of cas: 1878-68-8, Academic researchers, R&D teams, teachers, students, policy makers and the media all rely on us to share knowledge that is reliable, accurate and cutting-edge. 1878-68-8, Name is 4-Bromophenylacetic acid, SMILES is OC(=O)CC1=CC=C(Br)C=C1, belongs to phthalazine compound. In a article, author is Savjani, Nicky, introduce new discover of the category.

The new bis(iminopyridyl)phthalazine ligand, 1,4-{(2,6-i-Pr2C6H3)N=CMe)C5H3N}(2)C8H4N2 (L), has been prepared in good yield using a combination of palladium-mediated cross coupling and condensation strategies. Reaction of L with three equivalents of CoX2 (X = Cl, Br) in n-BuOH at elevated temperature generates, on crystallisation from bench acetonitrile, the paramagnetic tetrahalocobaltate salts [(L) Co2X(mu-X)(NCMe)(m)(OH2)(n)](CoX4) (X = Cl, m = 2, n = 1 1a; X = Br, m = 2, n = 0 1b) as acetonitrile or mixed acetonitrile/aqua adducts; a similar product is obtained from the reaction of FeCl2 with L and has been tentatively assigned as [(L)Fe2Cl(mu-Cl)(OH2)(3)](FeCl4) (2). By contrast, reaction of L with NiX2(DME) (X = Cl, Br; DME = 1,2-dimethoxyethane), under similar reaction conditions, affords the halide salts [(L) Ni2X2(mu-X)(OH2)(2)](X) (X = Cl 3a, X = Br 3b) as aqua adducts. Structural determinations on 1 and 3 reveal L to adopt a bis(tridentate) bonding mode allowing the halide-bridged metal centres to assemble in close proximity (M center dot center dot center dot M range: 3.437-3.596 angstrom). Unexpectedly, on reaction of L with ZnCl2, the neutral bimetallic [(L) Zn2Cl4] (4b) complex is formed in which the ZnCl2 units fill inequivalent binding sites within L (viz. the N-phth,N-py,N-im and N-py,N-im pockets). Complex 4b could also be obtained by the sequential addition of ZnCl2 to L to form firstly monometallic [(L) ZnCl2] (4a) and then on further ZnCl2 addition 4b; the fluxional behaviour of diamagnetic 4a and 4b is also reported. On activation with excess methylaluminoxane (MAO), 1-3 display modest activities for ethylene oligomerisation forming low molecular weight waxes with methyl-branched products predominating for the nickel systems (3). On the other hand, the iron catalyst (2) gives exclusively alpha-olefins while the cobalt systems (1) are much less selective affording equal mixtures of alpha-olefins and internal olefins along with lower levels of vinylidenes and tri-substituted alkenes. Single crystal X-ray structures are reported for L, 1a, 1b, 3a, 3b and 4. (C) 2015 Elsevier B.V. All rights reserved.

A novel BrOnsted acidic ionic liquid namely N,N-diethyl-N-sulfoethanamminium hydrogen sulfate ([Et3N-SO3H]HSO4) was synthesized, and characterized using FT-IR, H-1 NMR, C-13 NMR, and mass data. Then, its catalytic activity was examined for the preparation of triazolo[1,2-a]-indazole-triones and 2H-indazolo[2,1-b]phthalazine-triones by the one-pot multi-component condensation of arylaldehydes with dimedone and 4-phenylurazole/2,3-dihydrophthalazine-1,4-dione under solvent-free conditions. [Et3N-SO3H]HSO4 efficiently promoted the reaction to afford the products in high yields and in short reaction times.

A kinetic study of aqua substitution in dinuclear Pt(II) complexes, [{cis-Pt(OH2)(NH3)(2)}(2)-mu-pmn](ClO4)(2) (pmn), [{cis-Pt(OH2)(NH3)(2)}(2)-mu-pdn](ClO4)(2) (pdn), [{cis-Pt(OH2)(NH3)(2)}(2)-mu-qzn](ClO4)(2) (qzn), [{cis-Pt(OH2)(NH3)(2)}(2)-mu-pht](ClO4)(2) (pht) and [{cis-Pt(OH2)(NH3)(2)}(2)-mu-pzn](ClO4)(2) (pzn) (pmn = pyrimidine, pdn = pyridazine, qzn = quinazoline, pht = phthalazine, pzn = pyrazine) by different sulphur-donor nucleophiles, thiourea (TU), N,N-dimethylthiourea (DMTU) and N,N,N,N-tetramethylthiourea (TMTU) was carried out. The reactions were followed under pseudo-first-order conditions as a function of nucleophile concentration and temperature using stopped-flow and UV-Vis spectrophotometric methods. The reactivity of the nucleophiles follows the order TU > DMTU > TMTU. The general order of reactivity for the aqua complexes follows pzn > qzn > pmn > pdn > pht which is confirmed by the obtained pK (a) values and the quantum chemical calculated NBO charges at the metal centre. The negative values reported for the activation entropy confirm the associative nature of the substitution process. The results demonstrate the strong connection between structural and electronic characteristics of the diazine-bridging ligand and reactivity of the dinuclear Pt(II) complexes.

In view of the anticonvulsant activity reported for phthalazine derivatives as non-competitive AMPA receptor antagonists, a new series of phthalazine-1,4-diones (2-12) were designed and synthesized. The neurotoxicity was assessed using rotarod test. The molecular docking was performed for the synthesized compounds to assess their binding affinities toward AMPA receptor as non-competitive antagonists. The molecular modeling data were strongly interrelated to biological screening data. Compounds 8, 7(b), 7(a), 10 and 3(a) exhibited the highest binding affinities as non-competitive AMPA receptor antagonists and also showed the highest relative potencies of 1.78, 1.66, 1.60, 1.59 and 1.29, respectively, as anticonvulsants in comparison with diazepam. The most active compounds 8, 7(b), 7(a), 10 and 3(a) were further tested against maximal electroshock seizure (MES). Compounds 8 and 7(b) and 3(a) showed 100% protection at a dose level of 125 mu gm/kg, while compounds 7(a) and 10 exhibited 83.33% protection at the same dose level. These agents exerted low neurotoxicity and high safety margin in comparison with valproate as a reference drug. Most of our designed compounds exhibited good ADMET profile.

In a document, author is Berber, Nurcan, introduce the new discover, Recommanded Product: 31618-90-3.

A new series of phthalazine substituted urea and thiourea derivatives were synthesized, and their inhibitory effects on the activity of purified human carbonic anhydrases (hCAs I and II) were evaluated. 2H-Indazolo[2,1-b]phthalazine-trione derivative (1) was prepared with 4-nitrobenzaldehyde, dimedone, and phthalhydrazide in the presence of TFA in DMF, and nitro group was reduced to amine derivative (2) with SnCl2 center dot 2H(2)O. The compound was reacted with isocyanates and isothiocyanates to get the final products (3a-p). The results showed that all the synthesized compounds inhibited the CA isoenzymes activity. 3a (IC50 = 6.40 mu M for hCA I and 6.13 mu M for hCA II) has the most inhibitory effect. The synthesized compounds are very bulky to be able to bind near the zinc ion, and they much more probably bind as the coumarin derivatives.
