New ternary ligands consisting of an N4 bridging ligand and two terpyridines, and their Co(II) and Ni(II) dinuclear complexes. Structure, redox properties, and reaction with acid

Two ternary ligands consisting of two 2,2′:6′,2 ”-terpyridines and one N4-quadridentate mu(2),eta(2)-bridging ligand were synthesized. The N4 bridge is 1,4-bis(2-pyridyl)phthalazine in ligand 1, and 3,6-bis(2-pyridyl)pyridazine in ligand 2. Two Co(II) dinuclear complexes [(1)Co-2(mu-OH)](3+) and [(2)Co-2(mu-OH)](3+), and one Ni(II) dinuclear complex [(1)Ni-2(mu-Cl)](3+) were obtained. In the crystal structures of [(1)Co-2(mu-OH)](3+) and [(1)Ni-2(mu-Cl)](3+), two pyridine rings are twisted around the pyridine-phthalazine bonds to avoid steric repulsion between the hydrogen atoms. The pyridine rings also showed a significant tilt from the octahedral coordination plane, which causes the large positive shift of the first reduction potentials. Upon the addition of a proton, the cobalt dinuclear complexes can release one cobalt ion selectively, and the dinuclear complexes can be easily restored by the addition of a tertiary amine.

Phthalazine-1,4-dione derivatives as non-competitive AMPA receptor antagonists: design, synthesis, anticonvulsant evaluation, ADMET profile and molecular docking

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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 24324-17-2, you can contact me at any time and look forward to more communication. Product Details of 24324-17-2.

1,3-Diylideneisoindolines: Synthesis, Structure, Redox, and Optical Properties

Diiminoisoindoline (DII) is a crucial reagent for the synthesis of phthalocyanine as well as related macrocycles and chelates such as hemiporphyrazine and bis(iminopyridyl)isoindoline. In this report, we present the synthesis and characterization of four 1,3-diylideneisoindolines prepared via the reaction of several organic CH acids and DII. These orange or red compounds exhibit intense pi-pi* transitions in the UV visible region. The redox properties and electronic structures of all new compounds were investigated using cyclic voltammetry and density functional theory (DFT). The observed electrochemistry and UV-visible transitions are in good agreement with the DFT and time-dependent DFT calculations, which indicate that the HOMO is largely centered at the O=C-C-C=O fragments, and the lowest unoccupied molecular orbital is more extended onto the isoindoline unit.

Ionic liquid coated sulfonated carbon@titania composites for the one-pot synthesis of indeno[1,2-b]indole-9,10-diones and 1H-pyrazolo[1,2-b]phthalazine-5,10-diones in aqueous media

A highly active and stable ionic liquid based novel solid Bronsted acid catalyst (C@TiO2-SO3H-ILs) was prepared by coating a long chain ionic liquid onto sulfonated carbon@titania composites. The ionic liquid coating resulted in efficient stability and activity of C@TiO2-SO3H-ILs under aqueous conditions by creating a hydrophobic environment on the catalyst surface. The catalytic activity of the newly designed catalyst was tested in the one-pot multicomponent synthesis of indeno[1,2-b]indole-9,10-diones and 1H-pyrazolo[1,2-b]phthalazine-5,10-diones in aqueous media. The structure of the most active catalyst, C@TiO2-SO3H-IL1, before and after the coating with the ionic liquid was investigated by FTIR, TGA, XRD, CHNS, EDX, SEM and HRTEM. The catalyst allows easy recovery and excellent reusability for up to five catalytic runs without considerable loss of activity.

Solvent-free organic salt media mono symmetrical aza-Michael: synthesis of new N-mono substituted phthalhydrazide derivatives

In this paper, C-N bond formation between 2,3-dihydrophthalazine-1(4H),4-dione (phthalhydrazide) and alpha,beta-unsaturated esters was investigated and a new series of phthalazine derivatives was synthesized using an efficient and simple method under solvent-free conditions. An aza-Michael addition of phthalhydrazide to both acrylic and fumaric esters led to N-monosubstituted phthalhydrazides (as mono-Michael adduct) in the presence of tetrabutylammonium bromide as a high polar media, and 1,4-diaza-bicyclo[2,2,2] octane as an available organic base. In this reaction, the N1,N2-bis-Michael adduct was not observed at all. Also, reactions were performed at 90 degrees C and yields of products were good to excellent.
