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.

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.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2746-25-0. HPLC of Formula: https://www.ambeed.com/products/2746-25-0.html.

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.

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.

2,4,6-Triphenylaniline nanoemulsion formulation, optimization, and its application in type 2 diabetes mellitus

The secondary metabolite 2,4,6-triphenylaniline (TPA) was isolated from an endophytic fungi Alternaria longipes strain VITN14G of mangrove plant Avicennia officinalis, that exhibited satisfactory in vitro antidiabetic activity for type 2 diabetes mellitus (T2DM). The TPA was encapsulated using nanoemulsion (NE) to overcome the problem of stability and permeability to increase its therapeutic applications. Response surface methodology (RSM) was used for the optimization of the variables given, such as hydrodynamic diameter, surface charge, and polydispersity index (PDI). TPA was encapsulated using an optimized ratio of olive oil and tween 80 (2:1) significantly affected the response variables including particle size (124.8nm), zeta potential (-46.0mV), and PDI (0.396), and the encapsulation efficiency was found to be 95.93%. The TPA-loaded NE after MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) analysis showed nontoxic effects on L929 normal cell lines (areolar and adipose subcutaneous connective tissue of Mus musculus) with a viable percentage of 92%. In vitro release study revealed the slow and sustained release of the TPA over 48hrs from NE under the Fickian diffusion mechanism and followed the Higuchi model for release kinetics. Further, the percentage of alpha-glucosidase and alpha-amylase inhibition rate of TPA-loaded NE was found to be 78.5 and 43.42%, respectively. The present study, therefore, can aid in the development of a novel drug delivery system as a therapeutic approach to T2DM.

miR-489 suppresses multiple myeloma cells growth through inhibition of LDHA-mediated aerobic glycolysis

Background Dysregulation of miR-489 in human tumors has been widely reported. Lactate dehydrogenase isoform A (LDHA)-mediated aerobic glycolysis participates in proliferation of multiple myeloma (MM) cells. Objective To investigate whether miR-489 induced MM growth inhibition via targeting to LDHA-mediated aerobic glycolysis. Methods Expression of miR-489 in representative MM cell lines was determined via qRT-PCR (quantitative real-time polymerase chain reaction). MTT (3-(4, 5-di methyl thiazol-2-yl)-2, 5-di phenyl tetrazolium bromide) and colony formation assays were utilized to detect cell viability and proliferation. Effect of miR-489 on aerobic glycolysis was detected via glucose uptake, lactate and ATP production. Binding ability between miR-489 and LDHA was conducted via luciferase activity assay. Results MiR-489 was down-regulated in representative MM cell lines. Gain-of functional assays indicated that over-expression of miR-489 decreased cell viability and inhibited cell proliferation of MM cells. Moreover, miR-489 inhibited aerobic glycolysis via decrease of glucose uptake, lactate and ATP production. LDHA was identified as target of miR-489, suggesting a negative correlation between miR-489 and LDHA in MM cells. Mechanically, the inhibition ability of miR-489 on proliferation of MM cells was through inhibition of LDHA-mediated aerobic glycolysis. Conclusions miR-489 inhibited MM tumor growth via LDHA-mediated glycolytic metabolism, suggesting potential therapeutic target ability of miR-489/LDHA for MM.
