Matveevskaya, Vladislava V.; Pavlov, Dmitry I.; Samsonenko, Denis G.; Bonfili, Laura; Cuccioloni, Massimiliano; Benassi, Enrico; Pettinari, Riccardo; Potapov, Andrei S. published the artcile< Arene-ruthenium(II) complexes with tetracyclic oxime derivatives: synthesis, structure and antiproliferative activity against human breast cancer cells>, Synthetic Route of 67421-02-7, the main research area is ruthenium arene indenoquinoxalinone indenopyridopyrazinone tryptanthrin oxime complex preparation antitumor; crystal structure ruthenium arene indenoquinoxalinone indenopyridopyrazinone tryptanthrin oxime complex.

Six new arene-ruthenium(II) complexes containing two different η6-arene ligands – benzene and hexamethylbenzene, with indenoquinoxalinone oxime analogs (11H-indeno[1,2-b]quinoxalin-11-one oxime, 6H-indeno[1,2-b]pyrido[3,2-e]pyrazin-6-one oxime and 6-(hydroxyimino)indolo[2,1-b]quinazolin-12(6H)-one oxime (tryptanthrin-6-oxime)) as N,N’- chelating ligands are reported. The complexes were characterized by elemental anal., IR, UV-VIS, 1H and 13C NMR spectroscopy and by single-crystal X-ray structure anal. Complexes adopt a half-sandwich <> geometry with oxime ligands in anionic form, the ruthenium(II) center coordinates one arene, one N,N-bidentate oximate and one chloride ligand. The computational anal. of non-covalent intermol. interactions revealed weak attraction between the oxime oxygen atoms and the nearest hydrogen atoms of the oxime and the arene ligands. The cytotoxic activity of the complexes was evaluated against human breast cancer cell line MCF-7 and cisplatin-resistant human breast cancer cell line MCF-7CR as well as non-cancerous human breast epithelial cell line MCF10A. The cytotoxicity tests show micromolar IC50 values and tryptanthrin-6-oxime hexamethylbenzene-ruthenium(II) complex was found to exhibit the best antiproliferative activity among the studied compounds against the MCF-7 and MCF-7CR cell lines (IC50 9.0 ± 4.4 and 8.9 ± 1.5μM, resp.).

Wang, Yiping; Chen, Miao; Huang, Qunwu; Cui, Yong; Jin, Yanchao; Cui, Lingyun; Wen, Chen published the artcile< Experimental study of a solar-driven photo-electrochemical hybrid system for the decolorization of Acid Red 26>, Reference of 118-45-6, the main research area is Acid Red 26 dye decolorization photoelectrochem hybrid system.

This study presents a new solar-driven hybrid system that integrated a photo-electrochem. reactor with a photovoltaics (PV) panel for azo dyes decolorization and electricity generation. Full spectrum of sunlight is utilized to optimize the color removal of Acid Red 26 (AR26) in this hybrid system. Persulfate (PS, S2O2-4) was selected as the photochem. oxidant and Ti/IrO2-Ta2O5 electrode was used as the anode. Experiments were made to evaluate the efficiency of decolorization and the performance of PV panels in different reaction conditions outdoors. The results showed that the synergistic effect of two processes was observed for the AR26 decolorization. Comparing with the solar/persulfate process or the electrochem. process alone, the complete color removal time by the hybrid system decreased up to 50% and 44.4% resp. In this system, the water layer in the flow channel cooled PV panels by absorbing the far IR spectrum of sunlight, and the increased temperature of wastewater from 7°C to 16°C enhanced the decolorization efficiency of AR26. Moreover, the generated electricity by PV panels could satisfy the energy demand of electrochem. oxidation

Spiliotopoulos, Dimitrios; Koelbert, Cecile published the artcile< Assessment of the miniaturized liquid Ames microplate format (MPF) for a selection of the test items from the recommended list of genotoxic and non-genotoxic chemicals>, Electric Literature of 6055-19-2, the main research area is miniaturized liquid Ames microplate format genotoxic chem; 384-well plate test; Ames MPF test; Ames test; Comparative study; Genotoxicity; Liquid miniaturized microfluidic.

The Ames microplate format (MPF) is a miniaturized version of the plate agar Ames tests that takes advantage of a liquid microplate approach in 384-well plates with a color change-based readout. This method, already compared to the Ames test in Petri dishes, is used to assess the genotoxic potential of a variety of test items, including (but not limited to) chems., environmental samples, and drug candidates.61 chems. were selected from the updated recommended lists of genotoxic and non-genotoxic chems. for assessment of the performance of new or improved genotoxicity tests and tested in up to five bacterial strains. The agreement with the data from the scientific literature (over 90%) confirms the reliability of the Ames MPF as a cost-effective and 3R-compliant alternative to the regulatory Ames test that allows to predict and evaluate chems.’ mutagenicity in a faster, less laborious and, if available, automatable manner.

Obydennov, Konstantin L.; Kalinina, Tatiana A.; Galieva, Nadezhda A.; Beryozkina, Tetyana V.; Zhang, Yue; Fan, Zhijin; Glukhareva, Tatiana V.; Bakulev, Vasiliy A. published the artcile< Synthesis, Fungicidal Activity and Molecular Docking of 2-Acylamino and 2-Thioacylamino Derivatives of 1H-benzo[d]imidazoles as Anti-Tubulin Agents>, Quality Control of 162046-61-9, the main research area is benzimidazole preparation fungicidal mol docking; 5CA1; antifungal activity; benzimidazoles; carbendazim; molecular docking; nocodazole; tautomerism; tubulin.

This work dealt with the synthesis and evaluation of fungicidal activity of benzimidazole derivatives, which were structural analogs of com. anti-tubulin fungicides. A series of N-acyl and N-thioacyl derivatives of 2-amino-1H-benzo[d]imidazole I [R1 = H, Me, CF3, CO2Et; R2 = H; R3 = H, Me; R4 = Me, Ph, 2-thienyl, etc.; R1R2 = OCF2O; X = O, S] was prepared and their fungicidal activity against 13 strains of phytopathogenic fungi was studied. The most active compounds against the majority of the studied strains were compounds I [R1 = H, R2 = H, R3 = H, R4 = Ph, X = O; R1 = H, R2 = H, R3 = H, R4 = CF3, X = S; R1R2 = OCF2O, R3 = H, R4 = CF3, X = S] and the EC50 values of these compounds were in the range 2.5-20μg/mL. Compound I [R1 = H, R2 = H, R3 = H, R4 = Ph, X = O] showed the highest activity against the P. infestans strain, the growth of which was not suppressed by carbendazim. The formation of ligand-receptor complexes of various tautomeric forms of the studied benzimidazoles with homologous models of β-tubulins of B. cinerea, F. oxysporum, and P. infestans was modeled. Induced fit docking had been used for the simulation. The obtained data suggested the possibility of binding of benzimidazole fungicides to β-tubulin in the “”nocodazole cavity”” in the tautomeric form bearing a double exocyclic C=N bond. The importance of the formation of hydrogen bonds of benzimidazoles with the amino acid residue Val236 along with the Glu198 residue was also revealed in the present study.

Zender, Michael; Klein, Tobias; Henn, Claudia; Kirsch, Benjamin; Maurer, Christine K.; Kail, Dagmar; Ritter, Christiane; Dolezal, Olan; Steinbach, Anke; Hartmann, Rolf W. published the artcile< Discovery and biophysical characterization of 2-amino-oxadiazoles as novel antagonists of PqsR, an important regulator of Pseudomonas aeruginosa virulence>, COA of Formula: C8H6ClN3S, the main research area is aminooxadiazole antibacterial protein PqsR Pseudomonas.

The human pathogen Pseudomonas aeruginosa employs alkyl quinolones for cell-to-cell communication. The Pseudomonas quinolone signal (PQS) regulates various virulence factors via interaction with the transcriptional regulator PqsR. Therefore, the authors considered the development of PqsR antagonists as a novel strategy to limit the pathogenicity of P. aeruginosa. A fragment identification approach using surface plasmon resonance screening led to the discovery of chem. diverse PqsR ligands. The optimization of the most promising hit (5) resulted in the oxadiazole-2-amine 37 showing pure antagonistic activity in Escherichia coli (EC50 = 7.5 μM) and P. aeruginosa (EC50 = 38.5 μM) reporter gene assays. Compound 37 was able to diminish the production of the PQS precursor HHQ in a PqsH-deficient P. aeruginosa mutant. The level of the major virulence factor pyocyanin was significantly reduced in wild-type P. aeruginosa. In addition, site-directed mutagenesis in combination with isothermal titration calorimetry and NMR INPHARMA experiments revealed that the identified ligands bind to the same site of PqsR by adopting different binding modes. These findings might be utilized in a future fragment-growing approach aiming at novel therapeutic options for the treatment of P. aeruginosa infections.
