New coordination compounds have been synthesized by reacting Zn(II) and Co(II) nitrate or acetate in the presence of triethylamine with Schiff-base ligands containing diazine-ring, pyridine-2-carbaldehyde phthalazine-1-hydrazone,HzPYH, and di(2-pyridyl)ketone 3-chloro-pyridazine-6-hydrazone,HpDPKH. Complexes of[Co(HzPY)(2)]center dot 3.4H(2)O,[Zn(HzPY)(2)]and[Co(HpDPK)(2)]NO3 center dot H(2)Owere obtained. The crystal and the molecular structure of[Co(HzPY)(2)]center dot 3.4H(2)Owere determined using X-ray diffraction structure analysis. The compounds were characterized by elemental analysis, FT-IR and UV-Vis spectral data, conductivity and magnetic measurements, too. Except for the diamagnetic Co(III) compound with a nitrate counter-ion,[Co(HpDPK)(2)]NO3 center dot H2O, all the complexes are neutral-type. The magnetic moment of[Co(HzPY)(2)]center dot 3.4H(2)Oindicated a low-spin octahedral complex which is relatively rear amongst octahedral Co(II) complexes. Hence, its magnetic moment was measured in the temperature range of 3-300 K. To obtain products in the form of single crystals and/or to increase the yield, the reactions were carried out in solutions with different solvents or recrystallized from solvent mixtures. To determine the nature of the solvent (if any) in the crystalline products and to gain better insight into the decomposition mechanism, coupled TG-MS measurements were carried out. The desolvated compounds were stable at relatively high temperatures (> 200 degrees C). The cytotoxic, antiproliferative and efflux pump inhibitory effects of the compounds were tested in multidrug-resistant mouse T-lymphoma cells to study their effect on the suppression of MDR. The antibacterial activity of the compounds was also tested. The results of the antibacterial tests were analysed to understand better the effect of the central atoms and the structure on a specific activity.

Synthetic Route of 775-12-2, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 775-12-2 is helpful to your research.

3-Amino-2-benzenesulfonyl-1-alkyl/aryl-1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives were synthesized by the one-pot, three-component condensation of phthalhydrazide, aldehydes, and (phenylsulfonyl)acetonitrile in EtOH using 2-hydroxyethylammonium acetate as catalyst. The advantages of this method include environmental friendliness, easy work-up, and excellent yields. The reduction of some products and photophysical properties were also investigated.

A series of new phthalhydrazide-coumarin hybrids was obtained in the reaction of phthalhydrazide with corresponding bromopropoxycoumarin derivatives. These reactions were performed in the presence of Cs2CO3, in acetonitrile as solvent, and under reflux for 5 h. Obtained hybrids contain one or two coumarin scaffolds bonded to phthalhydrazide nitrogen via propoxy linker. Ten new phthalhydrazide-coumarin hybrids were obtained in moderate to good yields, and characterized with melting point, elemental analysis, IR and NMR spectroscopy, and LC-MS spectrometry. Additionally, the structures of these compounds were elucidated based on experimental and theoretical data (IR, H-1 NMR, and C-13 NMR). Excellent agreement between experimental and simulated spectra was achieved. The prediction of the potential biological activity of synthesized compounds was done using the online program PASS (Prediction of Activity Spectra for Substances). Based on the obtained results, the serotonin 2A receptor (5-HT2AR) was selected for molecular docking study. Molecular docking was also performed with commercially available drug Risperidone, and obtained results were compared with potential bioactive conformations of obtained phthalhydrazide-coumarin hybrids.

In this research, synthesis and characterization of a novel Schiff base Cu (II) complex immobilized on Fe3O4@SiO(2)nanoparticles are reported. Then, the catalytic activity of these nanoparticles as magnetic recyclable nanocatalyst was explored for the one-pot three-component synthesis of quinolin-5-one, chromene-3-carbonitrile and phthalazine-5,10-dione derivatives. The reactions proceeded smoothly to provide the respective products in excellent yields under green conditions. Facile preparation of the catalyst, high yields of the products, low reaction times, and use of water as green solvent are the main advantages of the present protocol. Moreover, the catalyst can be easily separated from the reaction mixture in a magnetic field, recycled and reused for six consecutive fresh runs without considerable loss of catalytic activity.

Blue highly fluorescent boron difluoride complexes based on phthalazine-pyridine

Three new boron difluoride complexes based on phthalazine-pyridine, denoted (6), (7) and (8), have been synthesized and their photophysical and electrochemical properties have been studied. Solutions of these new BF2-complexes exhibit an intense blue fluorescence under UV light at low concentrations. Fluorescence quantum yields (QYs) have been determined by photoluminescence (PL) spectroscopy and decay times (tau) by semi-empirical methods. QYs of (6), (7) and (8) vary from 25% to 79%. HOMO and LUMO energy levels have been estimated by cyclic voltammetry and PL spectroscopy. The HOMO and LUMO energy levels, at similar to -5.3 eV and similar to -2.3 eV, respectively, make these new complexes interesting candidates as blue emitters in OLED applications.
