The synthesis of four novel non-symmetric Ni(ii)-POCOP pincer complexes meta-functionalized with either benzothiazole or benzimidazole at the central aryl ring is described. All complexes were fully characterised in solution by various analytical techniques and the molecular structures in the solid state of complexes 1b, 2a and 2b were unequivocally determined by single crystal X-ray diffraction analysis. In addition, the Ni(ii)-POCOP pincer complexes were efficiently used as catalysts in the synthesis of diarylketones by cross-coupling reactions of functionalized benzaldehydes and boronic acid derivatives under relatively mild conditions. An important aspect of this transformation is the dependence on the steric properties of the donor groups (OPR2) of the pincer ligands, the more active compounds having the phosphinitos bearing isopropyl groups (1a and 2a) than those containing tert-butyl substituents (1b and 2b).

Herein we report, a single-pot multistep conversion of inactivated carboxylic acids to various N-containing compounds using a common synthetic methodology. The developed methodology rendered the use of carboxylic acids as a direct surrogate of primary amines, for the synthesis of primary ureas, secondary/tertiary ureas, O/S-carbamates, benzoyl ureas, amides, and N-formyls, exploiting the Curtius reaction. This approach has a potential to provide a diversified library of N-containing compounds, starting from a single carboxylic acid, based on the selection of the nucleophile.

A series of novel 2-amino-4-(3-hydroxy-4-phenoxyphenyl)-6-(4-substituted phenyl) nicotinonitriles were synthesized and evaluated against HepG2, A-549 and Vero cell lines. Compounds 3b (IC50 16.740.45 mu M) and 3p (IC50 10.57 +/- 0.54 mu M) were found to be the most active compounds against A-549 cell line among the evaluated compounds. Further 3b- and 3p-induced apoptosis was characterized by AO/EB (acridine orange/ethidium bromide) nuclear staining method and also by DNA fragmentation study. A decrease in cell viability and initiation of apoptosis was clearly evident through the morphological changes in the A-549 cells treated with 3b and 3p when stained with this method. Fragmentation of DNA into nucleosomes was observed which further confirmed the cell apoptosis in cells treated with compound 3b. Flow cytometry studies confirmed the cell cycle arrest at G2/M phase in A549 cells treated with compound 3b. Further in silico studies performed supported the in vitro anticancer activity of these compounds as depicted by dock score and binding energy values. [GRAPHICS] .

A palladium-catalyzed domino method for the direct synthesis of carbamates and ureas has been developed by using readily available and economical starting materials (aryl halide, carbon monoxide, sodium azide, amines and alcohols) in a one-pot approach. The domino process underwent carbonylation, Curtius rearrangement, and nucleophilic addition. This protocol provides a step-economical and highly efficient reaction to access the wide range of valuable carbamates, symmetrical and unsymmetrical ureas with high yields under remarkable mild reaction conditions that are important factors in pharmaceutical science, biochemistry and agricultural industries. Furthermore, the magnetically recoverable nanocatalyst (Fe3O4@SiO2/Pd(II)) can be conveniently and swiftly recycled using external magnet and reused at least for seven times without noticeable loss of its catalytic activity.

The resolution of samples containing unknown compounds of different nature, or without standards available, as is the case of chromatographic fingerprints, is still a challenge. Possibly, the most problematic aspect that prevents systematic method development is finding models that describe without bias the retention behaviour of the compounds in the samples. In this work, the use of global models (able to describe the whole sample) is proposed as an alternative to the use of individual models for each solute. Global models contain parameters that are specific for each solute, while other parameters -related to the column and solvent- are common for all solutes. A special regression procedure is presented for the construction of global models, which are applied to predict highly complex chromatograms, such as chromatographic fingerprints, for diverse experimental conditions in isocratic and gradient elution. Another interesting application is the prediction of molecular properties, such as log P-o/w from the specific solute parameters of the global models. The examined adapted models are based on the equations proposed by Snyder, Schoenmakers, Neue and Kuss, Jandera, and Bosch Roses to describe the retention. In all cases, the predictive capability was very satisfactory. Two cases of study were considered: chromatograms of camomile extracts analysed using acetonitrile gradients, and a set of 145 known compounds in a wide range of structures and functionalities, eluted isocratically with acetonitrile/water mobile phases.

Quality Control of 4′-Hydroxyacetophenone. I found the field of Oceanography very interesting. Saw the article Carbon isotopes and lignin phenols for tracing the floods during the past 70 years in the middle reach of the Changjiang River published in 2020.0, Reprint Addresses Wu, Y (corresponding author), East China Normal Univ, State Key Lab Estuarine & Coastal Res, Shanghai 210012, Peoples R China..

The Lake Tian E Zhou (TEZ, an oxbow lake) was formed during the rerouting of the Changjiang River in 1972, with strong influences from the main river channel and flood events. Herein, a sediment core was collected from the Lake TEZ for the measurements of carbon isotopes and biomarkers, including stable carbon isotopes (delta C-13), radiocarbon composition (Delta C-14), and lignin phenols, as well as lead-210 to reconstruct recent heavy flood events over the past 70 years. At the 24-26 cm interval, the sediment contained the highest OC%, TN%, and lignin phenols content, as well as significantly depleted C-13 but enriched C-14, corresponding to the extreme flood event in 1998. In addition, statistics from t-test showed that lignin phenols normalized to OC (?8), the concentration of 3, 5-dihydroxy benzoic acid (3, 5-BD), and the ratio of p-hydroxy benzophenone to total hydroxyl phenols (PHB/HP) were all significantly different between the layers containing flood deposits and the layers deposited under normal non-flood conditions (p<0.05). These results indicate that the later three parameters are highly related to flood events and can be used as compelling proxies, along with sediment chronology, for hydrological changes and storm/flood events in the river basin and coastal marine environments.

In this paper, the synthesis of magnetic cored amino group terminated dendrimer (Fe3O4@SiO2@PAMAM-G(2)) through covalent bonding was described. This catalyst was characterized by FT-IR, XRD, FE-SEM, TEM, and TGA detection methods. Next, the catalytic activity of this catalyst was investigated for the Knoevenagel condensation reaction of aldehydes with malononitrile under mild and solvent-free conditions. The Fe3O4@SiO2@PAMAM-G(2)could be separated from the reaction mixture by an external magnet and reused five times.

Carbon nano-onions (CNOs) are the least studied allotropes of carbon despite their discovery before nanotubes and fullerenes. CNOs are multilayered fullerenes concentrically arranged one inside the other resembling the structure of an onion. Typically, their size average ranges from 2 to 50 nm in diameter. Recently, CNOs have gained attention in different fields because of their interesting chemical and physical properties. However, their lack of dispersibility in common solvents due to strong intermolecular interactions limits their applications. Here, we studied the dispersion behavior of CNOs prepared by nanodiamond annealing in 20 solvents of different polarities. Dynamic light scattering and transmission electron microscopy were used to study the dispersion of CNOs in the different solvents. The solvents were classified as good or bad solvents to determine the Hansen solubility parameters (HSP) of the CNOs using various optimization approaches. The calculated HSPs (delta(D), delta(p) and delta(H)) were further used to predict the CNO dispersion behavior in other solvents with a very good agreement between expected and observed dispersibilities. Our results will be helpful to estimate the behavior of CNOs in other solvents or their interaction with other materials with known HSPs. (C) 2019 Elsevier B.V. All rights reserved.

Herein we describe the synthesis of five new 2-aryl and 2-alkylimidazolone derivatives via an effective one-pot synthetic strategy assisted by microwave irradiations which allowed us to access the desired product in a reduced time reaction compared to the thermal heating and a slightly better yield (48% compared to 45%). The new imidazolone derivatives were evaluated for their anticancer activity in vitro against MCF-7, MDA-MB-231 and HepG2 cell lines. The results showed good cytotoxic effects for some of these derivatives on both MCF-7 and HepG2 cell lines in the range of 5.7-11.3 mu M. Among the synthesized derivatives, 2ab and 2b showed the strongest activity with IC50 values of 7 and 5.7 mu M (MCF-7) and 6.2 and 8.6 mu M (HepG2), respectively. The cytotoxic activities of these derivatives were moderate compared to those of doxorubicin. However, this product showed higher toxicity in vivo on the development of zebrafish embryos than the synthesized imidazolones. These derivatives at high concentrations exhibited some morphological abnormalities on the embryos.

Self-immolation (SI) is the key principle of ProTide nucleotide prodrugs such as remdesivir, which is currently used to treat COVID-19 patients. Developing novel tailor-made SI systems requires new analytical methods for the detection and monitoring of SI. We developed a robust method for SI analysis using novel phosphate-based SI linkers with NMR traceable cyclic intermediates to distinguish SI from alternative fragmentation pathways and to monitor cargo release in real time.
