Regioselective synthesis of 2-and 4-diarylpyridine ethers and their inhibitory activities against phosphodiesterase 4B

Two diaryl ether regioisomers of pyridine were prepared through the CuI/TMEDA/Cs2CO3-catalyzed reaction of 2,4-dibromopyridine with phenol derivatives under nitrogen atmosphere. The polar solvent DMSO gave 4-isomer as the major product whereas less polar toluene resulted in 2-isomer as a major product. Structures of regioisomers were confirmed by single crystal X-ray diffraction analysis. 4-regioisomer shows higher biological activity against phosphodiesterase 4B (PDE4B) than that of 2-isomer. Molecular docking simulations revealed that the PDE4B-inhibitory activity difference between the two regioisomers was mainly attributed to the atomic charge difference on the -O- linker.

An Imidazo[1,2-a]pyridine Derivative That Enables Selective and Sequential Sensing of Cu2(+) and CN- Ions in Aqueous and Biological Samples

We report a triazole appended imidazopyridine based chemosensor (probe 1) for sequential detection of Cu2+ and CN- ions using fluorometry. Probe 1 is fluorescent in aqueous acetonitrile (H2O-CH3CN, 1:1, v/v) when common metal ions are present, but the fluorescence is quenched when Cu2+ is present. The binding mechanism, quantitative determination and the mode of interaction of Cu2+ with probe 1 are explained using fluorescence spectroscopy, electrospray ionization mass spectrometry and Density Functional Theory (DFT) calculations. The observed detection limit for Cu2+ is found to be (18.17 x 10(-6) M) and it is comparable with those reported for other Cu2+ chemosensors. Further, the 1-Cu2+ complex formation is found to be reversible, and this property has been successfully exploited for the quantitative determination of CN- ions in aqueous acetonitrile. Addition of CN- leads to a complete recovery of fluorescence from 1-Cu2+ complex, permitting the real time detection with the lower limit of detection of CN being 33.57 x 10(-6) M. The observed experimental results are supported by DFT calculations. A possible application of 1-Cu2+ in fluorescence imaging of Rhizoctonia solani mycelia cells, contaminated with CN ions, is also represented.

Synthesis of a novel Pd supported polymeric magnetic nanoparticles with urea-pyridine bridge: application as an efficient catalyst for the C-C and C-N bond formation

Here a novel Pd supported polymeric magnetic nanoparticles with urea-pyridine bridge (denoted as Fe3O4@/Urea-Pyridine/Pd) was synthesized and characterized. The Fe3O4@/Urea-Pyridine/Pd nanocatalyst was synthesized via a four steps process by using Fe3O4 nanoparticles, 3-(triethoxysilyl) propylisocyanate (TESPIC), 2,6 bis(propyl-triethoxysilylureylene) pyridine (BPS) and palladium chloride. The synthesized polymeric Fe3O4@/Urea-Pyridine/Pd nanocatalyst was analyzed through different analytical techniques, including FT-IR, NMR, XRD, VSM, TGA, DTA, ICP, FESEM, EDX, and BET. The described palladium supported polymeric magnetic nanoparticles with urea-pyridine bridge (Pd-MNPs) was used for the C-C and C-N coupling of phenylboronic acid with various amines and aryl halides in DMF as well as Sonogashira and Suzuki reactions in aqueous solution. Also, the Fe3O4@/Urea-Pyridine/Pd nanocatalyst exhibited high structural stability and excellent recyclability.

{P2V3W15}-Polyoxometalates Functionalized with Phthalocyaninato Y and Yb Moieties

A tris(alkoxo)pyridine-augmented Wells-Dawson polyoxometalate (nBu(4)N)(6)[WD-Py] (WD = P2V3W15O59(OCH2)(3)C, Py = C5H4N) was functionalized with phthalocyaninato metal moieties (MPc where M = Y or Yb and Pc = C32H16N8) to afford (nBu(4)N)(4)[HWD-Py(MPc)] compounds. High-resolution mass spectrometry was used to detect and identify the hybrid assembly. The magnetism studies reveal substantial differences between M = Yb (monomeric, single-ion paramagnetism) and M = Y (containing dimers, radical character). The results of electronic paramagnetic resonance spectroscopy, SQUID magnetometry, and magnetochemical calculations indicate the presence of intramolecular charge transfer from the MPc moiety to the polyoxometalate and of intermolecular charge transfer from the MPc moiety of one molecule to the polyoxometalate unit of another molecule. These compounds with identified V-IV ions represent unique examples of transition-metal/lanthanide complex-POM hybrid compounds with nonphotoinduced charge transfer between electron donor and acceptor centers.

The Masked Polar Group Incorporation (MPGI) Strategy in Drug Design: Effects of Nitrogen Substitutions on Combretastatin and Isocombretastatin Tubulin Inhibitors

Colchicine site ligands suffer from low aqueous solubility due to the highly hydrophobic nature of the binding site. A new strategy for increasing molecular polarity without exposing polar groups-termed masked polar group incorporation (MPGI)-was devised and applied to nitrogenated combretastatin analogues. Bulky ortho substituents to the pyridine nitrogen hinder it from the hydrophobic pocket while increasing molecular polarity. The resulting analogues show improved aqueous solubilities and highly potent antiproliferative activity against several cancer cell lines of different origin. The more potent compounds showed moderate tubulin polymerization inhibitory activity, arrested the cell cycle of treated cells at the G(2)/M phase, and subsequently caused apoptotic cell death represented by the cells gathered at the subG(0)/G(1) population after 48 h of treatment. Annexin V/Propidium Iodide (PI) double-positive cells observed after 72 h confirmed the induction of apoptosis. Docking studies suggest binding at the colchicine site of tubulin in a similar way as combretastatin A4, with the polar groups masked by the vicinal substituents. These results validate the proposed strategy for the design of colchicine site ligands and open a new road to increasing the aqueous solubility of ligands binding in apolar environments.

The spirobichroman-based polyimides with different side groups: from structure-property relationships to chain packing and gas transport performance

Spirobichroman-based polymers with high gas permeability and selectivity are promising for their applications as membranes in gas separation. In this study, three spirobichroman-based polyimides (PIs; 6FDA-FH, 6FDA-DH, and 6FDA-MH) were synthesised by the polyreaction between diamines containing different substituents (benzene ring, pyridine ring, and methyl group) and 4,4 ‘-(hexafluoroisopropylidene)-diphthalic anhydride (6FDA). The physical properties, gas transport behaviour, d-spacing, dihedral angle of molecules, and fractional free volume of the PIs were investigated through experiments and molecular simulations. The PIs exhibited excellent thermal stability and good solubility in common organic solvents. The gas permeability of the PIs was investigated; the results highlighted the critical role of the substituents in the enhancement of the gas separation performance of polymer membranes. Detailed analysis of the PIs showed that 6FDA-FH exhibits the highest gas permeability. This can be ascribed to the loose packing of the polymer chain owing to the increased dihedral angle between the two planes. However, the methyl substituent in 6FDA-MH disrupts the polymer chain packing rather than changing the dihedral angle between the two planes, thus enhancing the gas permeability of 6FDA-MH. Furthermore, 6FDA-DH exhibited the highest CO2/CH4 selectivity, which is attributed to the CO2 affinity of the polymer containing the pyridine unit.

Novel 2,6-disubstituted pyridine hydrazones: Synthesis, anticancer activity, docking studies and effects on caspase-3-mediated apoptosis

Novel pyridine-based dihydrazones (3a-l) were synthesized by the condensation of appropriate aldehydes and pyridine-2,6-dicarbohydrazide (2) which was obtained by the treatment of dimethyl pyridine-2,6-dicarboxylate (1) with hydrazine hydrate. Structures of all the synthesized compounds were supported by their FTIR, H-1 NMR, C-13 NMR and microanalytical data. The compounds were screened primarily for their antibacterial activities as well as anticancer activities. None of the synthesized compounds had important antibacterial activity. Among the compounds which were tested against human colon cancer cell line (HT-29), compounds 3f and 3k showed significant activity (IC50=6.78 mu M for compound 3f, IC50 = 8.88 mu M for compound 3k). In addition, compound 3g exhibited promising activity against Ishikawa human endometrial cancer cell line (ISH) with an IC50 value of 8.26 mu M. At 10 mu M, compounds 3f, 3k and 3g caused morphological changes of HT-29 and ISH cells and caspase-3 activation. In addition, these compounds were evaluated against NIH 3T3 mouse embriyonic fibroblast cell line and all synthesized compounds (3a-l) were found to be less toxic than paclitaxel. Moreover, possible inhibition mechanism of compound 3g was evaluated in silico against BRAF kinase enzyme. (C) 2020 Elsevier B.V. All rights reserved.

A New Look on Octet-Compliant Macrocyclic Organoaluminum Carboxylates as Dormant Poly-Lewis Acids

A more in-depth understanding of the multi-faceted chemistry of organoaluminum complexes is continually vital for the comprehension and development of new reagents and catalytic systems as well as molecular building blocks for modern functional materials. In this report we utilize a macrocyclic tetranuclear organoaluminum derivative of 2,3-naphthalenedicarboxylic acid (naphtha-H-2), [(Me2Al)(2)(naphtha)](2), as a model complex to probe both the dormant Lewis acidity and self-assembly processes of octet-compliant multinuclear macrocyclic organoaluminum compounds in the presence of mono- or bidentate pyridine ligands. The results nicely demonstrate that multinuclear octet-compliant organoaluminum clusters may effectively act as so-called poly-Lewis acids, utilizing their dormant Lewis acidity with the preservation or cleavage of the parent macrocycle depending on the character of both donor ligands and aromatic subunits of the dicarboxylate ligands.

Catalytic Degradation of 4-Ethylpyridine in Water by Heterogeneous Photo-Fenton Process

In this work, the degradation of 4-ethylpyridine (4EP) in water by a heterogeneous photo-Fenton process (H2O2/Fe3O4/ultraviolet irradiation (UV)) was investigated. More rapid and effective 4EP degradation was obtained with H2O2/Fe3O4/UV than Fenton-like (H2O2/Fe3O4) and UV/H2O2, which is due to the larger production of hydroxyl radicals from the chemical and photolytic decomposition of H2O2. The operational conditions were varied during 4EP degradation experiments to evaluate the effects of pH, catalyst, concentration, and temperature on the kinetics and efficiency of H2O2/Fe3O4/UV oxidation. Under optimal conditions (100 mg/L 4EP, [H2O2] = 1000 mg/L, Fe3O4 = 40 mg/L, pH = 3 and room temperature, 300 rpm), 4EP was totally declined and more than 93% of the total organic carbon (TOC) was eliminated. Liquid chromatography analysis confirmed the formation of aromatic and aliphatic intermediates (4-hydroxypyridine, 4-pyridone, malonic, oxalic, and formic acids) that resulted in being mineralized. Ion chromatography analysis demonstrated the stoichiometric release of NH4+ ions during 4EP degradation by heterogeneous photo-Fenton oxidation. The reuse of the heterogeneous catalyst was evaluated after chemical and heat treatment at different temperatures. The heat-treated catalyst at 500 degrees C presented similar activity than the pristine Fe3O4. Accordingly, heterogeneous photo-Fenton oxidation can be an alternative method to treat wastewaters and groundwater contaminated with pyridine derivatives and other organic micropollutants. The combination of heterogeneous photo-Fenton oxidation with classical biological methods can be proposed to reduce the overall cost of the treatment in large-scale water treatment plants.
