Copper-Catalyzed Asymmetric Coupling of Allenyl Radicals with Terminal Alkynes to Access Tetrasubstituted Allenes

In contrast to the wealth of asymmetric transformations for generating central chirality from alkyl radicals, the enantiocontrol over the allenyl radicals for forging axial chirality represents an uncharted domain. The challenge arises from the unique elongated linear configuration of the allenyl radicals that necessitates the stereo-differentiation of remote motifs away from the radical reaction site. We herein describe a copper-catalyzed asymmetric radical 1,4-carboalkynylation of 1,3-enynes via the coupling of allenyl radicals with terminal alkynes, providing diverse synthetically challenging tetrasubstituted chiral allenes. A chiral N,N,P-ligand is crucial for both the reaction initiation and the enantiocontrol over the highly reactive allenyl radicals. The reaction features a broad substrate scope, covering a variety of (hetero)aryl and alkyl alkynes and 1,3-enynes as well as radical precursors with excellent functional group tolerance.

Eco-Friendly Methodology for the Formation of Aromatic Carbon-Heteroatom Bonds by Using Green Ionic Liquids

A new sustainable method is reported for the formation of aromatic carbon-heteroatom bonds under solvent-free and mild conditions (no co-oxidant, no strong acid and no toxic reagents) by using a new type of green ionic liquid. The bromination of methoxy arenes was chosen as a model reaction. The reaction methodology is based on only using natural sodium bromine, which is transformed into an electrophilic brominating reagent within an ionic liquid, easily prepared from the melted salt FeCl3 hexahydrate. Bromination reactions with this in-situ-generated reagent gave good yields and excellent regioselectivity under simple and environmentally friendly conditions. To understand the unusual bromine polarity reversal of sodium bromine without any strong oxidant, the molecular structure of the reaction medium was characterised by Raman and direct infusion electrospray ionisation mass spectroscopy (ESI-MS). An extensive computational investigation using density functional theory methods was performed to describe a mechanism that suggests indirect oxidation of Br- through new iron adducts. The versatility of the methodology was successively applied to nitration and thiocyanation of methoxy arenes using KNO3 and KSCN in melted hexahydrated FeCl3.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 91-13-4, in my other articles.

An appropriate level of autophagy reduces emulsified isoflurane-induced apoptosis in fetal neural stem cells

Autophagy plays essential roles in cell survival. However, the functions and regulation of the autophagy-related proteins Atg5, LC3B, and Beclin 1 during anesthetic-induced developmental neurotoxicity remain unclear. This study aimed to understand the autophagy pathways and mechanisms that affect neurotoxicity, induced by the anesthetic emulsified isoflurane, in rat fetal neural stem cells. Fetal neural stem cells were cultured, in vitro, and neurotoxicity was induced by emulsified isoflurane treatment. The effects of pretreatment with the autophagy inhibitors 3-methyladenine and bafilomycin and the effects of transfection with small interfering RNA against ATG5 (siRNA-Atg5) were observed. Cell viability was determined using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, and apoptosis was assessed using flow cytometry. Ultrastructural changes were analyzed through transmission electron microscopy. The levels of the autophagy-related proteins LC3B, Beclin 1, Atg5, and P62 and the pro-apoptosis-related protein caspase-3 were analyzed using western blot assay. The inhibition of cell proliferation and that of apoptosis rate increased after treatment with emulsified isoflurane. Autophagolysosomes, monolayer membrane formation due to lysosomal degradation, were observed. The autophagy-related proteins LC3B, Beclin 1, Atg5, and P62 and caspase-3 were upregulated. These results confirm that emulsified isoflurane can induce toxicity and autophagy in fetal neural stem cells. Pre-treatment with 3-methyladenine and bafilomycin increased the apoptosis rate in emulsified isoflurane-treated fetal neural stem cells, which indicated that the complete inhibition of autophagy does not alleviate emulsified isoflurane-induced fetal neural stem cell toxicity. Atg5 expression was decreased significantly by siRNA-Atg5 transfection, and cell proliferation was inhibited. These results verify that the Atg5 autophagy pathway can be regulated to maintain appropriate levels of autophagy, which can inhibit the neurotoxicity induced by emulsified isoflurane anesthetic in fetal neural stem cells.

Detection of Viable Salmonella Typhimurium and Staphylococcus aureus in Coalho Cheese by Real-Time PCR

Real-time PCR (qPCR) has been used for rapid identification of Salmonella Typhimurium and Staphylococcus aureus in dairy foods, but is unable to differentiate viable and unviable pathogens. Ethidium bromide monoazide (EMA), a DNA-intercalating agent, can detect only viable cells because selectively enter cells considered unviable and bind to their DNA, inhibiting its amplification during qPCR. The objective was to establish a protocol for detection of viable Salmonella Typhimurium and S. aureus, experimentally inoculated in coalho cheese, by the use of EMA combined with qPCR. The protocol was effective for the identification of viable Salmonella Typhimurium in coalho cheese but not for the S. aureus cells. Concentrations of viable Salmonella Typhimurium cells of 1 CFU/10 g of coalho cheese could be detected. The monoplex protocol enables the rapid and specific identification of viable Salmonella Typhimurium in coalho cheese, making it an alternative method for the quality and safety control of cheeses.

Thermodynamic and exergic modelling of a combined cooling, heating and power system based on solid oxide fuel cell

In this research, thermodynamic and exergic analyses have been carried out on a combined cooling, heating and power cogeneration system that includes a solid oxide fuel cell and a single-effect lithium bromide absorption chiller. Results indicate that by increasing the system inlet air flow rate, the overall efficiency of the hybrid system is reduced, due to the reduction of the cell’s working temperature and exhaust gases temperature; while an increase in the working pressure of the system has no effect on its efficiency. The results also show that by raising the temperature of exhaust gases, the rate of exergy destruction diminishes, while the rate of exergy loss in the hybrid system increases. In the absorption chiller cycle, the maximum exergy destruction rate occurs in the generator, and the minimum rate is achieved in the pressure-reducing valve, between the evaporator and the condenser. Also, in the fuel cell cycle, the highest exergy destruction rate occurs in the heat exchanger of the inlet air to the cell, and the lowest exergy destruction rate occurs in the two water pumps. Moreover, the entropy generation rate and the exergy destruction rate of the fuel cell cycle are higher than those of the chiller cycle.

Eu2+: A suitable substituent for Pb2+ in CsPbX3 perovskite nanocrystals?

Eu2+ is used to replace toxic Pb2+ in metal halide perovskite nanocrystals (NCs). The synthesis implies injection of cesium oleate into a solution of europium (II) bromide at an experimentally determined optimum temperature of 130 degrees C and a reaction time of 60 s. Structural analysis indicates the formation of spherical CsEuBr3 nanoparticles with a mean size of 43 +/- 7 nm. Using EuI2 instead of EuBr2 leads to the formation of 18-nm CsI nanoparticles, while EuCl2 does not show any reaction with cesium oleate forming 80-nm EuCl2 nanoparticles. The obtained CsEuBr3 NCs exhibit bright blue emission at 413 nm (FWHM 30 nm) with a room temperature photoluminescence quantum yield of 39%. The emission originates from the Laporte-allowed 4f (7)-4f (6)5d(1) transition of Eu2+ and shows a PL decay time of 263 ns. The long-term stability of the optical properties is observed, making inorganic lead-free CsEuBr3 NCs promising deep blue emitters for optoelectronics. Published under license by AIP Publishing.

Synthesis, characterization, and cytotoxic activity studies of new N4O complexes derived from 2-({3-[2-morpholinoethylamino]-N3-([pyridine-2-yl]methyl) propylimino} methyl)phenol

A new unsymmetrical five-coordinate Schiff base ligand (HL) with an N4O donor set (2) has been prepared by condensation of N1-(2-morpholinoethyl)-N1-([pyridine-2-yl]methyl)propane-1,3-diamine with 2-hydroxy-benzaldehyde. Metal complexes [ML](n+) (M = Zn2+, Cd2+, Mn2+, Cu2+, Ni2+, Ag+, Fe3+, and Co2+ (3-10) were synthesized by the reaction of the ligand and metal salts in ethanol. The resulting products were characterized by elemental analyses, infrared, H-1 and C-13 nuclear magnetic resonance spectra (in the case of Cd and Zn complexes), UV-Vis, electrospray ionization-mass spectrometric, and conductivity measurements. The structure of the complexes [ZnL](ClO4) (3), [CdL](ClO4) (4), and [CuL](ClO4) (7) has been determined by single-crystal X-ray diffraction analysis. The metal complexes were determined to have a distorted trigonal bipyramidal (Zn and Cd) or a distorted square pyramidal (Cu) geometry. The cytotoxic potential of each compound (1-10) against MCF-7 and MDA-MB-231 (breast cancer cells), PC-3 (prostate cancer cells), and WI-38 human normal lung fibroblast cells was evaluated using the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide) assay. Compounds 1, 2, and 10 did not display any activity toward any cell line tested. None of the compounds except compound 8 was cytotoxic toward PC-3. Compounds 4 and 8 showed the highest cytotoxic activity against the MCF-7 and MDA-MB-231 cell lines. Because compounds 3, 6, and 9 have similar half-maximal inhibitory concentration values against cancer cells and normal cells, these compounds displayed poor selectivity between cancer and normal cells. More importantly, it was observed that compound 5 acts differently toward different types of cell lines. For example, it displays lower cytotoxicity against the WI-38 normal cell line than it does against the MDA-MB-231 cell line.

Radiation-Resistant CsPbBr3 Nanoplate-Based Lasers

The use of nanoscale lasers in new space technologies can enable a variety of applications. Metal lead halide perovskites have emerged and been verified to possess many unique properties for optoelectronic applications, which are key elements for the space mission system. However, the basic knowledge of radiation damage of perovskite materials and the in-depth experimental irradiation testing on their lasing properties are still lacking. Here, the performance of a CsPbBr3 nanoplate (NP) laser is measured to be maintained after exposure to 150 keV proton beam with fluence up to 1 x 10(15) p/cm(2), an extremely high level of collision that destroys CdS NPs with similar shapes and emission wavelengths. Lasing characteristics and carrier dynamics of the CsPbBr(3 )and CdS NPs have been studied and compared in detail before and after proton irradiation with different beam fluences. Concurrently, simulation results manifest that negligible atomic displacement damage is caused by proton bombardment in CsPbBr3, ensuring its high resistance to proton irradiation. The findings of the high radiation resistance of the CsPbBr3 NP lasers and the insights into the underlying mechanism are conceivably important, which might make recommendations for the development of perovskite coherent light sources for new space applications.

Anticancer Impacts ofTerminalia catappaExtract on SW480 Colorectal Neoplasm Cell Line

Purpose Colorectal cancer (CRC) is one of the most lethal and prevalent cancers throughout the world. Despite the remarkable advance in the field, drug resistance still remains as an unresolved problem in cancer. Hence, finding effective compounds with minimal side effects to fight cancer is of central priority. Herbal products have been traditionally used to prevent and treat a variety of diseases. Methods In the present study, the antitumor effect ofTerminalia catappaplant ethanolic extract (TCE) was assessed on SW480 CRC model cell line. In this regard, effects of TCE were evaluated on the proliferation, apoptosis, and migration of SW480 cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, Annexin V/PI flow cytometry, and scratch tests, respectively. Furthermore, changes in the expression of genes involved in these events including Bax, Bcl-2, Caspase 3, Caspase 8, Caspase 9, MMP-13, miR-21, and miR-34a were measured by quantitative real-time PCR (qRT-PCR). Results According to the MTT results, TCE reduced the proliferation of SW480 cells significantly. The flow cytometry test also revealed a notable rate of apoptosis induction after TCE treatment. An inhibitory effect on cell migration was also evident in scratch test. Expression patterns of the assessed genes also changed subsequent to TCE treatment. Conclusion The results of this study indicated thatT. catappacould be considered as a potential source of anticancer compounds and a candidate for further investigations.

MODIFICATION OF Ti-6Al-4V ALLOYS FOR DENTAL IMPLANT AND ITS CAPACITY TO GROW HUMAN OSTEOBLAST ATCC

Modification of Ti-6Al-4V alloys with silver-loaded TiO2 nanotubes was investigated. In this study, TiO2 nanotube (TiNT) was grown on the surface of Ti-6Al-4V plates by means of anodization in an electrolyte solution containing glycerol, water and 0.5 wt.% of NH4 F. Silver particles were deposited on TiNT using a Photo-Assisted Deposition (PAD) method. Formation of crystalline phase of TiO2 on the surface was confirmed by means of XRD while its superficial morphology was observed using FESEM/EDS. Hydrophilicity was assessed by means of contact angle measurement. As-synthesized silver-loaded TiNT on osteoblast ATCC growth in vitro was also investigated in terms of its capacity in supporting osseointegration. The cell viability was determined by MTT (3-[4,5-dimethylthiazol-2yl]-2,5dipheny1-2H-tetrazolium bromide) assay and its differentiation activity was measured by alkaline phosphatase (ALP) assay. The results showed that desposition of silver on TiNT increased cell viability after 14 days culture while improving the hydrophilicity feature. Silver-loaded TiNT on Ti-6Al-4V alloy with Ag precursor concentration of 0.10 M showed the optimum viability of osteoblast growth, with 14% improvement in comparison to its unmodified counterpart. The MTT assay showed that no cytotoxicity in vitro was observed on this material. This study provides corroborating evidences that the modification of Ti-6Al-4V alloy may enhance the cell viability and its prominence as dental implant materials.
