New hydrophilic fluorescent selective ion sensor based on phenazine and phthalazine moieties, 1,1′-(phenazine-2,3-diyl)-bis(3-(1,4-dihydroxyphthalazin-6-yl)urea) (1), has been designed, synthesized and characterized. Interestingly, sensor 1 exhibits prominent turn-on and turn-off’ fluorogenic signaling at 580 nm towards Fe2+ & AcO- and Sr2+ & Cu2+, respectively. The fluorescence titration experiments shed light on the nature of the interaction between 1 and guest molecules (Fe2+, Sr2+, Cu2+ and AcO-), which divulge that 1 is flexible enough to orient itself according to the size of the guest molecule. Water mediated excited-state intramolecular proton transfer (ESIPT) and photo-induced electron transfer (PET) mechanisms are responsible for the dual behavior of 1, which binds with guest molecules in 1:1 stoichiometry, Based on the significant duplex fluorescence response of 1, a molecular logic gate keypad lock with sixteen on passwords for a storage system has been developed.

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.

The fermentation of the endophyte Fusarium oxysporum SS46 and Fusarium oxysporum ATCC MYA 4623 with epigenetic modulator hydralazine in Czapek medium led to the isolation of 3-methyl-1,2,4-triazolo [3,4-alpha] phthalazine (1). The mechanism of biotransformation involves reaction with acetyl-CoA and further cyclization, and was unveiled using C-13-precursor. Additionally, AFLP technique for genomic DNA and differential gene expression (cDNA) analyses were applied for comparative profiling of the fungus under and without treatment with hydralazine. There was no change in the DNA profile of hydralazine-treated and non-treated cultures; however, cDNA-AFLP analyses showed a differential gene expression in the cultures after treatment of the fungi with hydralazine.

Phthalazine (2,3-diazanaphthalene) and phthalhydrazide (2,3-dihydro-1,4-phthalazinedione) compounds are heterocycles with several biological properties. Most recently, analogous phthalazine-triones also emerged as drug candidates. Herein, we introduced a phthalazine-trione moiety as a promising fluorophore in the blue and green spectral regions. This desired optical property was rationalized based on their crystal structure and time-dependent density functional theory (TD-DFT) calculations. Under ultraviolet (UV) excitation (ca. 360 nm), two light emission maxima at ca. 460 nm and 480 nm were observed for ten phthalazine-triones, regardless of the substitution pattern. This conservation in the light-emitting property was rationalized by our time-dependent DFT calculations for the three phthalazine-triones whose crystal geometries were also determined in this study (4-chlorophenyl, 3-methoxyphenyl and 4-nitrophenyl derivatives) and for those available in literature (4-fluorophenyl and 4-bromophenyl derivatives). Electronic transitions with the largest oscillator strengths were near 360 nm and were in excellent agreement with the experimental excitation energy (UV-visible and photoluminescence spectra). Lifetime values of selected samples could also be determined, which were between 1.59 ns and 3.21 ns. In all compounds, the Frontier molecular orbitals involved in these excitations were distributed over the phthalazine-trione moiety and were not localized on the changeable substituent.

Three new dinuclear Pd(II) complexes with general formula [{Pd(en)Cl}(2)(mu-L)](NO3)(2) [L is bridging ligand quinoxaline (Pd1), quinazoline (Pd2) and phthalazine (Pd3)] were synthesized and characterized by elemental microanalyses, UV-Vis, IR and NMR (H-1 and C-13) spectroscopy. The interaction of dinuclear Pd1-Pd3 complexes with calf thymus DNA (CT-DNA) has been monitored by viscosity measurements, UV-Vis and fluorescence emission spectroscopy in aqueous phosphate buffer solution (PBS) at pH 7.40 and 37 degrees C. In addition, these experimental conditions have been applied to investigate the binding affinities of Pd1-Pd3 complexes to the bovine serum albumin (BSA) by fluorescence emission spectroscopy. In vitro antiproliferative and apoptotic activities of the dinuclear Pd(II) complexes have been tested on colorectal and lung cancer cell lines. All tested Pd(II) complexes had lower cytotoxic effect than cisplatin against colorectal cancer cells, but also had similar or even higher cytotoxicity than cisplatin against lung cancer cells. All complexes induced apoptosis of colorectal and lung cancer cells, while the highest antiproliferative effect exerted Pd2 complex. [GRAPHICS]

Waste to wealth: conversion of nano-magnetic eggshell (Fe3O4@Eggshell) to Fe3O4@Ca(HSO4)(2): cheap, green and environment-friendly solid acid catalyst

Eggshell is a hazardous waste by European Union regulations, so that discarded thousands of tons per year. To convert waste (eggshell) to wealth (catalyst), nano-magnetic eggshell was prepared based on the nano-Fe3O4, and then the eggshell was converted to Ca(HSO4)(2) with organic acid, namely, chlorosulfonic acid. Based on the back titration, 5.18mmol SO4H group was loaded per gram of the nano-structure. Using this method eggshell was converted to cheap, green and environment-friendly solid acid catalyst. The prepared catalyst (nano- Fe3O4@Ca(HSO4)(2)) was characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and thermal gravimetric analysis (TGA). The activity of eggshell waste-derived catalysts was successfully evaluated in the synthesis of value-added products, namely indazolo[1,2-b]-phthalazinetrione derivatives as a benchmark multicomponent reaction. In addition, design of experiments shows that increase in amount of catalyst (and temperature), boost the reaction yield, especially with steeper slope at higher temperature.

beta-Alanine-functionalized magnetic graphene oxide quantum dots: an efficient and recyclable heterogeneous basic catalyst for the synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione and 2,3-dihydroquinazolin-4(1H)-one derivatives

In this research, we report a novel synthesis of magnetic beta-alanine-functionalized-graphene oxide quantum dots Fe3O4@GOQDs-N-(beta-alanine) as a recyclable and eco-friendly heterogeneous nanocatalyst. The catalytic efficiency of these nanosheets was explored as a basic catalyst for a one-pot three-component synthesis of various 1H-pyrazolo[1,2-b]phthalazine-5,10-dione and 2,3-dihydroquinazolin-4(1H)-one derivatives. The reactions proceeded smoothly under mild and green conditions to afford the respected products in excellent yields. The structure of this newly fabricated catalyst was successfully confirmed by different analytical techniques such as Fourier transform infrared spectroscopy, X-ray diffraction, field emission-scanning electron microscopy, high-resolution transmission electron microscopy, energy-dispersive X-ray spectroscopy, vibrating sample magnetometry, and thermogravimetric analysis. The stability and recyclability of the catalyst were examined by performing the model reaction in six consecutive runs. The recovered catalyst from the first run was directly used for the next runs with no significant loss of catalytic activity.
