I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Inhibition of nitric oxide and prostaglandin E-2 production by pyrrolylated-chalcones: Synthesis, biological activity, crystal structure analysis, and molecular docking studies published in 2020.0. Safety of 2,5-Dimethoxybenzaldehyde, Reprint Addresses Faudzi, SMM (corresponding author), Univ Putra Malaysia, Fac Sci, Dept Chem, Serdang 43400, Selangor, Malaysia.. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde

In search of potent anti-inflammatory agents, twenty-four chalcone derivatives including seven new compounds (13 – 17, 21 and 23) containing pyrrole moiety were designed, synthesized, and assessed for their nitric oxide (NO) and prostaglandin E-2 (PGE(2)) suppression ability on IFN-gamma/LPS-induced RAW 264.7 macrophage cells. Results showed that none of the synthesized compounds were PAINS-associated molecules, with 3-(2,5-dimethoxyphenyl)-1-(1H-pyrrol-2-yl) prop-2-en-1-one (compound 16) exhibiting remarkable inhibition activity towards PGE(2) and NO production with IC50 values of 0.5 +/- 1.5 mu M and 12.1 +/- 1.5 mu M, respectively. Physicochemical and ADMET studies showed that majority of the compounds obey to Lipinski’s rule of five (RO5) having high blood brain barrier (BBB) penetration, human intestinal absorption (HIA), P- glycoprotein (PgP) inhibition and plasma binding protein (PPB) inhibition. The obtained atomic coordinates for the single-crystal XRD of 16 were then applied in a molecular docking simulation, and compound 16 was found to participate in a number of important binding interactions in the binding sites of ERK and mPGES-1. Based on these results, we have observed the potential of compound 16 as a new hit anti-inflammatory agent, and these findings could serve as a basis for further studies on its mechanism of action.

Karmel, C; Chen, ZW; Hartwig, JF in [Karmel, Caleb; Chen, Zhewei; Hartwig, John F.] Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA published Iridium-Catalyzed Silylation of C-H Bonds in Unactivated Arenes: A Sterically Encumbered Phenanthroline Ligand Accelerates Catalysis in 2019, Cited 57. Name: 1,3-Dimethoxybenzene. The Name is 1,3-Dimethoxybenzene. Through research, I have a further understanding and discovery of 151-10-0.

We report a new system for the silylation of aryl C-H bonds. The combination of [Ir(cod)(OMe)](2) and 2,9-Me-2-phenanthroline (2,9-Me-2-phen) catalyzes the silylation of arenes at lower temperatures and with faster rates than those reported previously, when the hydrogen byproduct is removed, and with high functional group tolerance and regioselectivity. Inhibition of reactions by the H-2 byproduct is shown to limit the silylation of aryl C-H bonds in the presence of the most active catalysts, thereby masking their high activity. Analysis of initial rates uncovered the high reactivity of the catalyst containing the sterically hindered 2,9-Me-2-phen ligand but accompanying rapid inhibition by hydrogen. With this catalyst, under a flow of nitrogen to remove hydrogen, electron-rich arenes, including those containing sensitive functional groups, undergo silylation in high yield for the first time, and arenes that underwent silylation with prior catalysts react over much shorter times with lower catalyst loadings. The synthetic value of this methodology is demonstrated by the preparation of key intermediates in the synthesis of medicinally important compounds in concise sequences comprising silylation and functionalization. Mechanistic studies demonstrate that the cleavage of the aryl C-H bond is reversible and that the higher rates observed with the 2,9-Me-2-phen ligand are due to a more thermodynamically favorable oxidative addition of aryl C-H bonds.

I found the field of Pharmacology & Pharmacy very interesting. Saw the article Synthesis of benzotriazoles derivatives and their dual potential as alpha-amylase and alpha-glucosidase inhibitors in vitro: Structure-activity relationship, molecular docking, and kinetic studies published in 2019. Name: 2,6-Difluorobenzoic acid, Reprint Addresses Khan, KM (corresponding author), Univ Karachi, Int Ctr Chem & Biol Sci, HEJ Res Inst Chem, Karachi 75270, Pakistan.. The CAS is 385-00-2.

Benzotriazoles (4-6) were synthesized which were further reacted with different substituted benzoic acids and phenacyl bromides to synthesize benzotriazole derivatives (7-40). The synthetic compounds (7-40) were characterized via different spectroscopic techniques including EI-MS, HREI-MS, H-1-, and C-13 NMR. These molecules were examined for their anti-hyperglycemic potential hence were evaluated for alpha-glucosidase and alpha-amylase inhibitory activities. All benzotriazoles displayed moderate to good inhibitory activity in the range of IC50 values of 2.00-5.6 and 2.04-5.72 mu M against alpha-glucosidase and alpha-amylase enzymes, respectively. The synthetic compounds were divided into two categories A and B, in order to understand the structure-activity relationship. Compounds 25 (IC50 = 2.41 +/- 131 mu M), (IC50 = 2.5 +/- 1.21 mu M), 36 (IC50= 2.12 +/- 1.35 M), (IC50 = 2.21 +/- 1.08 mu M), and 37 (IC50 = 2.00 +/- 1.22 mu M), (IC50 = 2.04 +/- 1.4 mu M) with chloro substitution/s at aryl ring were found to be most active against alpha-glucosidase and alpha-amylase enzymes. Molecular docking studies on all compounds were performed which revealed that chloro substitutions are playing a pivotal role in the binding interactions. The enzyme inhibition mode was also studied and the kinetic studies revealed that the synthetic molecules have shown competitive mode of inhibition against alpha-amylase and non-competitive mode of inhibition against alpha-glucosidase enzyme.

I found the field of Chemistry very interesting. Saw the article Catalytic Decarboxylative C-N Formation to Generate Alkyl, Alkenyl, and Aryl Amines published in 2021. Safety of 2,6-Difluorobenzoic acid, Reprint Addresses Lu, HJ (corresponding author), Nanjing Univ, Sch Chem & Chem Engn, Jiangsu Key Lab Adv Organ Mat, Inst Chem & Biomed Sci, Nanjing 210093, Peoples R China.. The CAS is 385-00-2. Through research, I have a further understanding and discovery of 2,6-Difluorobenzoic acid

Transition-metal-catalyzed sp(2) C-N bond formation is a reliable method for the synthesis of aryl amines. Catalytic sp(3) C-N formation reactions have been reported occasionally, and methods that can realize both sp(2) and sp(3) C-N formation are relatively unexplored. Herein, we address this challenge with a method of catalytic decarboxylative C-N formation that proceeds through a cascade carboxylic acid activation, acyl azide formation, Curtius rearrangement and nucleophilic addition reaction. The reaction uses naturally abundant organic carboxylic acids as carbon sources, readily prepared azidoformates as the nitrogen sources, and 4-dimethylaminopyridine (DMAP) and Cu(OAc)(2) as catalysts with as low as 0.1 mol % loading, providing protected alkyl, alkenyl and aryl amines in high yields with gaseous N-2 and CO2 as the only byproducts. Examples are demonstrated of the late-stage functionalization of natural products and drug molecules, stereospecific synthesis of useful alpha-chiral alkyl amines, and rapid construction of different ureas and primary amines.

In subsurface bioremediation, electron donor addition promotes microbial Fe(lII)-oxide mineral reduction that could change soil pore structure, release colloids, and alter soil surface properties. These processes in turn may impact bioremediation rates and the ultimate fate of contaminants. Columns packed with water-stable, Fe-oxide-rich soil aggregates were infused with acetate-containing artificial groundwater and operated for 20 d or 60 d inside an anoxic chamber. Soluble Fe(II) and soil colloids were detected in the effluent within one week after initiation of the acetate addition, demonstrating Fe(III)-bioreduction and colloid formation. Diffusible Br-, less diffusible 2,6-difluorobenzoate (DFBA), and non-diffusible silica-shelled silver nanoparticles (SSSNP) were used as tracers in transport experiments before and after the bioreduction. The transport of Br- was not influenced by the bioreduction. DFBA showed earlier breakthrough and less tailing after the bioreduction, suggesting alterations in flow paths and soil surface chemistry during the 20-d bioreduction treatment. Similarly, the bioreduction increased the transport of SSSNP very significantly, with mass recovery increasing from 1.7% to 25.1%. Unexpectedly, the SSSNP was completely retained in the columns when the acetate injection was extended from 20 to 60 d, while the mass recovery of DFBA decreased from 89.1% to 84.1% and Br showed no change. The large change in the transport of SSSNP was attributed to soil aggregate breakdown and colloid release (causing mechanical straining of SSSNP) and the exposure of iron oxide surfaces previously unavailable within aggregate interiors (facilitating attachment of SSSNP). These results suggest a time dependent fashion of microbial effect on the transport of diffusivity-varying tracers. (C) 2018 Elsevier Ltd. All rights reserved.

This study presents one-pot multicomponent preparation of 1,8-dioxo-octahydroxanthene derivatives under very mild conditions using cobalt-incorporated sulfated zirconia (ZrO2/SO42-/Co) as an efficient heterogeneous recyclable multifunctional nanocatalyst. The nanocatalyst was successfully characterized by FTIR, XRD, TGA, FE-SEM, TEM, ICP, and EDX analyses. The nanoparticles have a mean size of 13 nm, with a combination of the monoclinic-tetragonal crystal structure. A wide scope of aldehydes bearing different functional groups was condensed with dimedone and/or 1,3-cyclohexadione in water at room temperature with good-to-high yields at short reaction times. The catalyst can be efficiently recovered and reused several times without much loss of its activity. Besides, hot filtration test gives more insight into the heterogeneous nature of the catalyst. Finally, a plausible mechanism for this transformation was proposed. Graphical abstract A facile and convenient method for the synthesis of 1,8-dioxo-octahydroxanthenes has been developed using cobalt-incorporated sulfated zirconia as an efficient recyclable nanocatalyst.

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.
