In this wok, a novel Bi24O31Br10/nano-ZnO composite photocatalyst has been synthesized with solvothermal method. The photocatalytic ability of the composite photocatalyst is estimated through degrading Rhodomine B (RhB) under visible light. The RhB degradation rate exceeds 90% in 40 min for the Bi24O31Br10/nano-ZnO (5%) composite, showing the most remarkable photocatalytic abilities. The excellent photocatalytic performance can be explained by the successful detachment and motion of photo-induced electrons (e(-)) and holes (h(+)) in the composite photocatalyst. Additionally, a probable photo-catalytic principle of the Bi24O31Br10/nano-ZnO composite for RhB degradation is discussed. This study could provide an original visible light driven photocatalyst on efficiently purifying dye wastewaters.

This study evaluated the effects of freezing, prior to and after dry aging, on the microbiological and physical-chemical quality of beef. Strip loins (n = 24) from 12 carcasses were assigned to four treatments: non-frozen dry aging (Dry); dry aging, steak fabrication, freezing and slow thawing (Dry + ST); freezing, fast thawing (FT; 20 degrees C/15 h) and dry aging (FT + Dry); freezing, slow thawing (ST; 4 degrees C/48 h) and dry aging (ST + Dry). Freezing conditions were – 20 degrees C/28 days and dry aging conditions were 2 degrees C/70% relative humidity, for 28 days. Freezing prior to dry aging did not affect the microbial counts compared to Dry. However, FT + Dry and ST + Dry increased (16%) total process loss (P < .05) compared to Dry and Dry + ST. Moreover, freezing changed volatile compounds profile. Thus, freezing prior to dry aging was not a feasible process due to increased process loss, while freezing after dry aging was considered a viable alternative to preserve the steaks without compromising beef physical-chemical traits.

UV/Vis absorption and NMR spectroscopy titrations have been used to investigate the formation of complexes between cations and neutral H-bond acceptors in organic solvents. Complexes formed by two different H-bond acceptors with fifteen different cations were studied in acetone and in acetonitrile. The effects of water and ion pairing with the counter-anion were found to be negligible in the two polar solvents employed for this study. The data were used to determine self-consistent H-bond donor parameters (a) for a series of organic and inorganic cations; guanidinium, primary, tertiary and quaternary ammonium, imidazolium, methylpyridinium, lithium, sodium, potassium, rubidium and caesium. The results demonstrate the transferability of a parameters for cations between different solvents and different H-bond acceptor partners, allowing reliable prediction of cation recognition properties in different environments. Lithium and protonated nitrogen cations form the most stable complexes, but the a parameter is only 5.0, which is similar to the neutral H-bond donor 3-trifluoromethyl, 4-nitrophenol (a 1/4 5.1). Quaternary ammonium is the weakest H-bond donor investigated with an a value of 2.7, which is comparable to an alcohol. The a parameters for alkali metal cations decrease down the group from 5.0 (Li+) to 3.5 (Cs+).

Indomethacin is a well-known nonsteroidal anti-inflammatory drug that has cytotoxic activity. In this study, a new series of structurally related indomethacin analogues was synthesized using simple chemical approaches, and their cytotoxic effects against five different human cancer cell lines (colon cancer cell lines HCT-116, HT-29 and Caco-2, hepatic cell line HepG-2 and breast cell line MCF-7) were evaluated. Most of the tested compounds displayed potent anti-cancer activity, especially against the three colon cancer cell lines. Among all tested derivatives, compound 12 demonstrated the most potent cytotoxic activity compared to the parent drug indomethacin and the reference compound 5-fluorouracil, with IC 50 values ranging 0.83-1.54 mu M. A mechanistic study of the most active compound against the HCT-116, HT-29 and Caco-2 cell lines revealed cell cycle arrest during the G2/M phase. Compound 12 was found to induce apoptosis through the up-regulation of Bax and p53 by 7.4 and 8.5-fold, respectively, and also the downregulation of Bcl-2 by 3.2-fold compared to the control. Western blot assay was performed on HCT-116 cells and demonstrated marked inhibition of CDK1 and Bcl-2 expression together with an increase in the expression of caspase-3, Bax and p53 in a concentration-dependent manner. Finally, a prediction of the chemo-informatic properties of compounds 11 and 12 indicated that they are orally bioavailable with no permeation of the blood-brain barrier. (C) 2020 Elsevier B.V.

In this study, an efficient hybrid nanocatalyst made of guar gum (guarana, as a natural basis), magnetic iron oxide nanoparticles, and copper(I) oxide nanoparticles (Cu2O NPs) is fabricated and suitably applied for catalyzing the multicomponent (three- and four-component) synthesis reactions of imidazole derivatives. Here, an easy preparation strategy for this novel catalytic system (Cu2O/Fe3O4@guarana) is presented. Then, the application of this catalytic system for the synthesis of imidazole derivatives is precisely investigated. For this purpose, ultrasonication is introduced as an efficient and fast method. In summary, the high catalytic efficiency of Cu2O/Fe3O4@guarana nanocomposite is well demonstrated by high reaction yields obtained in the presence of a small amount of this nanocomposite, under mild conditions. Wide active surface area, substantial magnetic behavior, excellent heterogeneity, suitable stability, well reusability, and etc. have distinguished this catalytic system as an instrumental tool for facilitating the complex synthetic reactions.

One-pot Julia olefination using ribofuranosyl sulfones is described. The alpha-anomers of the ribofuranosyl sulfones were synthesized with complete alpha-selectivity via the glycosylation of heteroarylthiols using ribofuranosyl iodides as glycosyl donors and the subsequent oxidation of the resulting heteroaryl 1-thioribofuranosides with magnesium monoperphthalate (MMPP). The Julia olefination of the alpha-ribofuranosyl sulfones with aldehydes proceeded smoothly in one pot to afford the thermodynamically less stable (E)-exo-glycals with modest-to-excellent stereoselectivity (up to E/Z = 94:6) under the optimized conditions. The E selectivity was especially high for aromatic aldehydes. In contrast, the (Z)-exo-glycal was obtained as the main product with low stereoselectivity when the corresponding beta-ribofuranosyl sulfone was used (E/Z = 41:59). The remarkable impact of the anomeric configuration of the ribofuranosyl sulfones on the stereoselectivity of the Julia olefination has been rationalized using density functional theory (DFT) calculations. The protected ribose moiety of the resulting exo-glycals induced completely a-selective cyclopropanation on the exocyclic carbon-carbon double bond via the Simmons-Smith-Furukawa reaction. The 2-cyanoethyl group was found to be useful for the protection of the exo-glycals, as it could be removed without affecting the exocyclic C=C bond.

A recent experiment has revealed that additive free ester hydrogenation by Co-pincer complexes might follow an unusual non-bifunctional mechanism, however, the detailed mechanistic pathway is missing. It has been predicted that several intermediates and transition states are involved, having their essential role in the catalytic performances. Detailed theoretical studies are therefore essential in this regard for achieving more efficient ester hydrogenation catalysts. On the basis of first principles calculations, performed over Co(PNP)/(PNN) complexes, we present here the energetics and mechanistic details, showing the distinct orientations of different possible intermediates and transition states, and find the minimum energy pathway for the conversion of esters to alcohols. In the way, we find that some intermediates must undergo structural distortion for achieving the lowest potential energy barrier which must have a severe impact on the catalytic turnover frequency.

Hydrotalcite (HT) modified with magnetic nanoparticle and thiol groups for the immobilization of silver to the preparation of Fe3O4/HT-SH-Ag was used. The catalyst was completely characterized using XRD, ICP, SEM, EDS, VSM, FT-IR, and TEM analyzes. The Fe3O4/HT-SH-Ag catalyst is useful in oxidizing of primary and secondary aliphatic and benzyl alcohols to the relevant carbonyl products (aldehyde/ketone). To demonstrate the effect of Ag over the reaction, Fe3O4/HT-SH catalyst performance, and also some other control tests were studied. For this purpose, the model reaction was carried out in the presence of AgNO3, HT (I), and Fe3O4/HT (II), and low yield was obtained (20-50%). High to good efficiency were obtained for all entries, whether benzaldehyde derivatives, in short times. The catalyst can be reused for several continuous runs with a simple external magnet without losing significant reactivity.

New antibacterial drugs are urgently needed to tackle the rapid rise in multi-drug resistant bacteria. DNA gyrase is a validated target for the development of new antibacterial drugs. Thus, in the present investigation, a novel series of 1,2,4-oxadiazole-chalcone/oxime (6a-f) and (7a-f) were synthesized and characterized by IR, NMR (1H and 13C) and elemental analyses. The title compounds were evaluated for their in-vitro antimicrobial activity by the modified agar diffusion method as well as their E. coli DNA gyrase inhibitory activity. The minimum inhibitory concentration (MIC) and the structure activity relationships (SARs) were evaluated. Among all, compounds 6a, 6c-e, 7b and 7e were the most potent and proved to possess broad spectrum activity against the tested Gram-positive and Gram-negative organisms. Additionally, compounds 6a (against S. aureus), 6c (against B. subtilis and E. hirae), 6e (against E. hirae), 6f, 7a and 7c (against E. coli) and 7d (against B. subtilis), with MIC value of 3.12 mu M were two-fold more potent than the standard ciprofloxacin (MIC = 6.25 mu M). Mechanistically, compounds 6c, 7c, 7e and 7b had good inhibitory activity against E. coli gyrase with IC50 values of 17.05, 13.4, 16.9, and 19.6 mu M, respectively, in comparison with novobiocin (IC50 = 12.3 mu M) and ciprofloxacin (IC50 = 10.5 mu M). The molecular docking results at DNA gyrase active site revealed that the most potent compounds 6c and 7c have binding mode and docking scores comparable to that of ciprofloxacin and novobiocin suggesting their antibacterial activity via inhibition of DNA gyrase. Finally, the predicted parameters of Lipinski’s rule of five and ADMET analysis showed that 6c and 7c had good drug-likeness and acceptable physicochemical properties. Therefore, the hybridization of the chalcone and oxadiazole moieties could be promising lead as antibacterial candidate which merit further future structural optimizations.
