Phenanthroline ligands and [Ir(cod)(OMe)](2) form complexes that catalyze the silylation of aromatic and aliphatic C-H bonds. However, no experimental data on the identity of complexes related to the mechanism of this process or the mechanisms by which they react to functionalize C-H bonds have been reported. Herein, we describe our studies on the mechanism of the iridium-catalyzed silylation of aryl C-H bonds. The resting state of the catalyst is an iridium disilyl hydride complex (phenanthroline)Ir(SiMe(OTMS)(2))(2)(H)(L), in which L varies with the arene and additives. An iridium disilyl hydride complex was isolated, characterized, and allowed to react with arenes to form aryl silanes. The kinetics of the reactions of electron-rich and electron-poor arenes showed that the rate-limiting step varies with the electronic properties of the arene. Computational studies on related iridium silyl complexes revealed that the high activity of iridium complexes containing sterically encumbered phenanthroline ligands is due to a change in the number of silyl groups bound to iridium between the resting state of the catalyst containing the hindered phenanthroline and that containing less-hindered phenanthroline.

Macrocyclic peptides are promising scaffolds of bioactive compounds and clinical therapeutics. Herein, we develop a strategy for the macrocyclization of biaryl-bridged peptides through late-stage Pd-catalyzed C(sp(2))-H arylation. This method displays broad substrate scope and high efficiency in the synthesis of peptide conjugates with various bioactive molecules. Furthermore, we applied this method to prepare peptide macrocycles with aryl-aryl cross-links. Our results show the effectiveness of backbone amide groups as directing groups in Pd-catalyzed C-H functionalization of peptides.

VEGF/VEGFR-2 signaling plays a critical part in tumor angiogenesis. Inhibition of this pathway has been considered as a promising approach for cancer treatment. In this work, a series of 6,7-dimethoxy-4-anilinoquinazoline derivatives bearing diarylamide moiety were designed, synthesized and evaluated as potent inhibitors of VEGFR-2 kinase. Their in vitro antiproliferation activities against two human cancer cell lines Hep-G2 and MCF-7 have also been determined. Among them, compound 14b exhibited the most potent inhibitory activity against VEGFR-2 with IC50 value of 0.016 +/- 0.002 mu M and it showed the most potent antiproliferative effect against Hep-G2 and MCF-7 with IC50 values at low-micromolar range. Molecular docking studies revealed that these compounds represented by the most potent compound 14b could bind well to the ATP-binding site of VEGFR-2, which suggested that compound 14b could be a potential anticancer agent targeting VEGFR-2.

Lignins from different tree barks, including Norway spruce (Picea abies), eucalyptus (Eucalyptus globulus), mimosa (Acacia dealbata) and blackwood acacia (A. melanoxylon), are thoroughly characterized. The lignin from E. globulus bark is found to be enriched in syringyl (S) units, with lower amounts of guaiacyl (G) and p-hydroxyphenyl (H) units (H/G/S ratio of 1:26:73), which produces a lignin that is highly enriched in beta-ether linkages (83 %), whereas those from the two Acacia barks have similar compositions (H/G/S ratio of approximate to 5:50:45), with a predominance of beta-ethers (73-75 %) and lower amounts of condensed carbon-carbon linkages; the lignin from A. dealbata bark also includes some resorcinol-related compounds, that appear to be incorporated or intimately associated to the polymer. The lignin from P. abies bark is enriched in G units, with lower amounts of H units (H/G ratio of 14:86); this lignin is thus depleted in beta-O-4 ‘ alkyl-aryl ether linkages (44 %) and enriched in condensed linkages. Interestingly, this lignin contains large amounts of hydroxystilbene glucosides that seem to be integrally incorporated into the lignin structure. This study indicates that lignins from tree barks can be seen as an interesting source of valuable phenolic compounds. Moreover, this study is useful for tailoring conversion technologies for bark deconstruction and valorization.

Recently I am researching about FLUORINATED GRAPHENE; SENSING PROPERTIES; NANOCOMPOSITE; FABRICATION; ADSORPTION; TRANSPARENT; SENSITIVITY; COVALENT; SYSTEMS; FILMS, Saw an article supported by the Government of India by World BankThe World Bank India. Published in ELSEVIER SCIENCE SA in LAUSANNE ,Authors: Kumar, R; Kumar, A; Singh, R; Kashyap, R; Kumar, R; Kumar, D; Sharma, SK; Kumar, M. The CAS is 99-04-7. Through research, I have a further understanding and discovery of 3-Methylbenzoic acid. Computed Properties of C8H8O2

A gas sensor has been fabricated by depositing the thin film of Functionalized Graphene Oxide (GO) using Langmuir Blodget (LB) technique on SiO2/Si wafers. Aluminum (Al) contacts were deposited using thermal evaporation technique for measuring the resistance of fabricated thin film. Three different concentrations (15 mM, 50 mM, 75 mM) of Meta Toluic acid (MTA) have been used for functionalization of GO. X-Ray Diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and Raman spectroscopy were used to characterize the Graphene Oxide (GO) after functionalization. Also, Scanning Electron Microscopy (SEM) was carried out for both GO and functionalized GO to study the surface morphology. Gas sensing behavior of functionalized GO has been investigated using two probe resistance measurement method for different concentration of ammonia gas. Sensor response was studied for ammonia concentration varied from 100 to 2000 ppm. Highest response obtained at 100 ppm concentration was found to be similar to 12.2% for sample TG(75). Higher concentration of MTA (up to a critical value) in GO leads to higher response of ammonia gas. This enhanced gas response has been due to the increased ester formation reaction at the surface of sensing film, which eventually leads to more interaction with NH3 gas molecules. In addition, defects and carbon vacancy in functionalized GO also acts as the trapping sites for gas molecules being sensed. The selectivity of the sensor has been investigated in different environment and sensor was found to be very selective towards ammonia gas. For stability investigation of the fabricated sensor, the sensor response has been recorded for 45 days.

I found the field of Chemistry very interesting. Saw the article Visible light driven, nickel-catalyzed aryl esterification using a triplet photosensitiser thioxanthen-9-one published in 2019.

We report an approach to the visible light-initiated, nickel-catalyzed esterification of carboxylic acids with aryl bromides. Thioxanthen-9-one works as a triplet photosensitizer to significantly accelerate this cross-coupling to provide aryl esters in moderate to excellent yields at room temperature. A mechanistic investigation indicates that this esterification undergoes the stepwise oxidative addition of an arylbromide to nickel, transmetalation of an aryl-Ni(ii) bromide complex, energy transfer from thioxanthen-9-one to an excited-state aryl-Ni(ii) carboxylate and reductive elimination to the aryl ester. This study contributes to the utilization of ketones as triplet photosensitisers in photochemical transformations.

An efficient and BF3 center dot Et2O-catalyzed chemoselective synthesis of diversified 1,3-diarylisobenzofuran in a high yield has been described. The reaction proceeds through sequential hydroarylation-cyclization between 2-formylarylketones and electron-rich arenes/heteroarenes. Advantageous features of the developed methodology include operational simplicity, a broad substrate scope, and applicability towards gram scale synthesis. The utility of isobenzofuran derivatives as the diene was extended to the synthesis of [4+2] cyclo-adducts with DMAD and the synthesis of 1,2-dicarbonylarenes in good yields.

A series of 15 novel 1,3,4-thiadiazole amide derivatives containing a protocatechuic acid moiety were synthesized and structurally characterized. In addition, the corresponding imino (4) and amino (5) analogues of a phenyl-substituted 1,3,4-thiadiazole amide derivative 3a were prepared to compare the effects of the structural changes on the radical-scavenging activity. The obtained compounds were examined for their antioxidative potential by 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. In addition, selected compounds were studied by density functional theory (DFT) and cyclic voltammetry experiments. The tested compounds showed high potential to scavenging DPPH radical and ABTS radical cation compared with the referent antioxidants ascorbic acid and nordihydroguaiaretic acid (NDGA). On the basis of the calculated thermodynamic parameters, it can be concluded that the sequential proton loss electron transfer (SPLET) mechanism represents the most probable reaction path in a polar solvent for DPPH radical-scavenging activity. On the other hand, the single electron transfer followed by proton transfer (SET-PT) can be a likely mechanistic pathway in the case of an ABTS radical cation. (C) 2019 Academie des sciences.

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.
