Two new coordination complexes of Cu(ii) viz.; [Cu(bpy)(2)(NO3)]NO3 center dot 5H(2)O (1) and [Cu(phen)(Hdmpz)Cl-2]center dot H2O (2) (bpy = 2,2 ‘-bipyridine, phen = 1,10-phenanthroline, Hdmpz = 3,5-dimethyl pyrazole) have been synthesized and characterized by single crystal X-ray diffraction, electronic spectroscopy, EPR, FT-IR spectroscopy and TGA. The nitrate anion and the water molecules in the lattice of 1 are involved in the formation of unconventional infinite supramolecular crown-like nitrate-water clusters. The unconventional enclathration of guest cationic complex moieties of 1 within the supramolecular nitrate-water crown hosts provides stability to the crystal structure. Crystal structure analysis of 2 reveals the presence of cooperative ternary pi-stacked assemblies with enclathration of single guest water molecules in hexameric Cu(II) supramolecular host cavities. Theoretical calculations have been performed to analyse the non-covalent interactions in the compounds; focusing on the unusual H-bonding network/anion-pi cooperative assemblies in 1 and two different pi-stacked cooperative assemblies in 2. DFT studies reveal that the distribution and orientation of the H-bonds in the cooperative H-bonding network in 1 is the most favoured. The high interaction energies of (pi-pi)(1) and (pi-pi)(2) in pi-stacked ternary assemblies of 2 can be attributed to the participation of the entire aromatic surfaces with antiparallel orientations and the cooperative C-H center dot center dot center dot Cl interactions respectively. The in vitro antiproliferative activities of the compounds considering cell cytotoxicity, apoptosis and DNA fragmentation assays reveal significant concentration dependent cytotoxicity in DL cancer cells with nominal effects in normal PBMC cells. The molecular docking and pharmacophore studies established the structure activity relationship of the compounds.

A pyridine-pyrazole-pyrene-based chemosensor,L, has been developed and fully characterized by all the possible techniques (ESI-MS, NMR, CHN, IRetc.). It has been found that the probe,L, selectively recognizes Cu(2+)ion and Fe(3+)ion fluorogenically and chromogenically, respectively, among a wide range of competitive metal ions. It has been demonstrated that the probe is not only metal ion-selective but also oxidation state-selective for Fe(3+)ions. The metal complexes (Cu and Fe) of the ligand were synthesized and characterized using different spectroscopic techniques and they were also characterised X-ray structurally as well, which confirm the stoichiometry (L : M = 2 : 1). The sensitivities for the fluorogenic sensing of Cu(2+)ions and chromogenic sensing of Fe(3+)have been found to be as low as nano molar level detection (69 nM and 27 nM, respectively). Further studies reveal that the Cu(II)L(2)complex can act as a turn-off fluorescent chemosensor for S(2-)ions and Fe(III)L(2)can act as a reversible turn-off colorimetric chemosensor for F(-)ions over other anions.

A metal-free promoted direct oxidative C-N bond coupling of quinoxalinones and azoles for the rapid and effective synthesis of potent pharmaceutical important 3-(azol-1-yl)quinoxalin-2-one has been developed. Employing PIDA as the easily available mediator, the desired coupling products were isolated in moderate to excellent yields with a good substrate scope under operational simplicity and mild reaction conditions. Preliminary mechanistic studies suggested that a radical process is likely to be involved in the reaction. (C) 2020 Elsevier Ltd. All rights reserved.

A sequential and general strategy has been successfully developed for the synthesis of spiropyrazolone scaffolds. This intriguing transformation of the asymmetric multicomponent catalysis process was realized with the combination of Michael addition/chlorination/nucleophilic substitution in a one-pot sequence, giving rise to a series of spiropyrazolones with fully substituted cyclopropanes and spiro-dihydrobenzofurans containing continuous stereogenic centers in good yields with excellent stereoselectivities.

Background: The Islamic Republic of Iran is at high risk of natural disasters. Households are the basic unit of society and they need to be prepared for disasters. Aims: This study assessed disaster preparedness among Iranian households in 2015. Methods: Using multistage cluster sampling, 2968 households in the catchment area of 53 public health departments in all 30 provinces of the Islamic Republic of Iran were surveyed on the disaster preparedness measures they had taken in the past year. The data collection questionnaire included 15 disaster preparedness measures. The mean preparedness score was calculated and its association with residence (urban versus rural), house ownership (owner versus renter) and education level of the head of the household (illiterate, elementary school, middle school, high school, university) was evaluated. Results: The mean score for household disaster preparedness was 9.3 out of 100 (95% confidence interval: 8.3-10.3). Multivariate analysis showed higher preparedness among rural than urban households (P = 0.02). Higher education level was positively associated with a higher preparedness score (P < 0.001), as was house ownership (P < 0.001). Conclusion: The level of household disaster preparedness in the Islamic Republic of Iran in 2015 was low. In line with the first priority for action of the Sendai Framework for Disaster Risk Reduction, the current study provides an overall picture of household disaster preparedness in the Islamic Republic of Iran. This estimation can be used as a baseline value for policy-making, planning, and evaluation of public awareness of disasters in the country.

We have reported the synthesis, characterization, and catalytic applications of amorphous iron nanoparticles (FeNPs) using aqueous leaves extract of renewable natural resourceBoswellia serrataplant. Synthesized FeNPs were stabilized in situ by the addition of aqueous pod extracts ofAcacia concinnaas a biosurfactant (pH 3.11). The structural investigation of biosynthesized nanoparticles was performed using UV-visible spectroscopy, X-ray diffraction analysis, selected area electron diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, thermogravimetric analysis, and BET analysis. The FeNPs were amorphous in nature with average particle size similar to 19 nm and successfully employed as heterogeneous catalyst for the synthesis of quinoxaline, benzimidazole, and pyrazole derivatives in aqueous medium at ambient conditions. The FeNPs could be recycled up to five times with modest change in the catalytic activity. [GRAPHICS] .

Azoles are emerging contaminants that are resistant to biodegradation during wastewater treatment. Their presence has been widely reported in wastewater effluents and receiving waters. In this work, the potential inhibition of nitrification process by six different azole compounds in wastewater treatment plants was investigated in batch bioassays. The azoles studied included three diazoles: pyrazole (Pz); 1-methylpyrazole (MePz); 3,5-dimethylpyrazole (DMePz); and three triazoles: 1,2,4-triazole (Tz); benzotriazole (BTz); and 5-methyl benzotriazole (MeBTz). The concentration of azoles causing 50% inhibition (IC50) increased (azoles became less inhibitory) in the following order (mg L-1): BTz (1.99) < MeBTz (218) < Pz (2.69) < Tz (3.53) < DMePz (17.3) < MePz (49.6). No clear structure-inhibitory relationships were found using Log P and pKa as structural properties. The toxicity of any given azole may be related to the role of substituent groups on disabling/enabling binding to the active sites of metallo-enzymes in nitrifying microorganisms. This is exemplified by the low toxicity of MePz, which has a cyclic N blocked by a methyl group. The observed inhibition caused to nitrifying bacteria is more severe than their cytotoxicity to other target organisms (e.g., methanogens and heterotrophic bacteria), suggesting a specific inhibition to the copper-containing enzyme, ammonium monooxygenase, in ammonia oxidizing nitrifying microorganisms.

The catalytic enantioselective diorganozinc additions to cyclic diketones including pyrazolin-4,5-diones and isatins have been developed. In the presence of morpholine-containing chiral amino alcohol ligand, the corresponding chiral cyclic tertiary alcohols were produced in good to excellent yields (up to 97 %) and enantioselectivities (up to 95 % ee). The notable feature of this protocol includes its mild reaction conditions, Lewis acid additives free and broad functional group tolerance.
