A new series of octadec-9-enoic acid schiff base entities (S1-S30) were designed and synthesized targeting peroxisome proliferator activated receptor-gamma for agonist action. Molinspiration software (online) was used to estimate drug like molecular properties of the metabolites. Docking disquisition on co-crystallized protein of PPAR-gamma (PDB ID 1FM9) was carried out which showed S21, S10 and S7 as best situated in the vital sites of receptor having docking scores – 9.19, – 8.68 and – 8.64 respectively. Free binding energy measured using model of Maestro 9.0 and was in range of from – 40.01 and – 80.54 kcal/mol, significant when compared with pioglitazone (- 51.58 Kcal/mol). Seven best docked derivatives were assessed for in-vivo oral glucose tolerance on normal rats and anti-hyperglycaemic activity by streptozotocin induced diabetes model. S21 unveiled to be the best measured analogue among all the synthesized entities. Encouraging outcomes motivates fatty acids for further development of more effective and safer compounds.

A nickel-catalyzed arylation of both aliphatic and aromatic aldehydes proceeds with air-stable (hetero)arylboronic acids, with an exceptionally wide substrate scope. The neutral condition tolerates acidic hydrogen and sensitive polar groups and also preserves alpha-stereocenters of some chiral aldehydes. Interestingly, this nickel(0) catalysis does not follow common 1,2-insertion of arylmetal species to aldehydes and beta-hydrogen elimination.

Application In Synthesis of 3-Hydroxybenzaldehyde. I found the field of Energy & Fuels; Engineering very interesting. Saw the article Nontarget Analysis of Oxygenates in Catalytic Fast Pyrolysis Biocrudes by Supercritical Fluid Chromatography High-Resolution Mass Spectrometry published in 2019.0, Reprint Addresses Christensen, JH (corresponding author), Univ Copenhagen, Fac Sci, Dept Plant & Environm Sci, Thorvaldsensvej 40, DK-1871 Frederiksberg, Denmark.. The CAS is 100-83-4. Through research, I have a further understanding and discovery of 3-Hydroxybenzaldehyde.

Catalytic fast pyrolysis (CFP) biocrudes can comprise up to 30 wt % of oxygen content in compounds such as polyphenols, acids, carbonyls, and anhydrosugars and thus require upgrading by, e.g., hydrotreatment, to produce transport fuels. The chemical characterization of phenolic and acidic compounds in biocrudes is of great importance to optimize the CFP process. In this study, an analytical workflow is proposed for nontarget chemical fingerprinting analysis of CFP biocrudes using supercritical fluid chromatography high-resolution mass spectrometry (SFC-HRMS) with negative electrospray ionization (ESI-), followed by multivariate data analysis. The method was developed and tested on five biocrude samples from loblolly pine (Pinus taeda) with varying oxygen content (14.9-28.8 wt % wet basis) due to different CFP conditions. The pixel-based analysis displayed chemical variation between all samples. Twenty-four regions of interest were tentatively identified, including mono- and polyphenols, fatty acids, and methylated and methoxylated phenols. The identification workflow and MS/MS analysis were prioritized on the peaks with the highest relative concentration. The developed SFC-ESI–HRMS method shows high repeatability and analyzed oxygen-containing compounds with hydroxyl and/or carboxyl moieties in combination with other moieties of up to 400 Da.

An efficient, mild and environmentally benign protocol has been developed for the synthesis of aminouracil-tethered tri-substituted methane derivatives. The three-component reaction of 2-hydroxy-1,4-naphthaquinone, 6-amino-1,3-dimethyluracil and aldehydes in the presence of molecular iodine as catalyst under reflux conditions resulted in aminouracil-tethered tri-substituted methane derivatives 4 in aqueous medium. Similarly, the four-component reaction of 2-hydroxy-1,4-naphthaquinone, o-phenylenediamine, aldehydes and aminouracil derivatives resulted in aminouracil-tethered tri-substituted methane derivatives 6 under the same reaction conditions. The notable features of this protocol are simple experimental procedure, cheap catalyst, readily available starting materials, moderate-to-good yields of the products having biologically active important moieties such as aminouracil, hydroxy-naphthaquinone/benzophenazine.

In this study, a PVAm-bearing SO3H groups/Fe3O4 nanocomposite was prepared via a simple and in situ polymerization of acrylamide onto the surface of magnetic nanoparticles without using organosilane precursors. In order to obtain amine-functionalized magnetic, Hofmann degradation was carried out. In the following, sulfonated-polyvinyl amine coated on Fe3O4 nanoparticles was prepared by covalent grafting of chlorosulfonic acid on amine groups. The introduction of polymer to the surface of magnetic nanoparticles increases the loading content with functional groups extremely. The resulting hybrid material was effectively employed as an unprecedented acid magnetic catalyst for the one-pot synthesis of 2,4,5-trisubstituted and 1,2,4,5-tetrasubstituted imidazoles under solvent-free conditions. High yields, mild reaction conditions, short reaction times, operational simplicity with reusability are the notable features of the catalyst. The structure of the newly developed catalyst was characterized using TGA, FT-IR, SEM, TEM, VSM, EDX, CHNS, and XRD analysis. Magnetic separation and recycling of the catalyst for at least 8 runs is possible without any significant deterioration in catalytic activity. This work is the first report of employing PVAm as a linker for immobilizing liquid acid on a support.

A novel synthetic method for flavonol from 2′-hydroxyl acetophenone and benzaldehyde promoted by pyrrolidine under an aerobic condition in water is established. This protocol was supported by efficient synthesis of 44 common examples and three natural products. The alpha, beta-unsaturated iminium ion (enimine ion E) was proved to be the key intermediate in the reaction. (H2O)-O-18 and O-18(2) isotope tracking experiments demonstrated that both water and the aerobic atmosphere were necessary to ensure the transformation. The selectivity for flavonol or aurone was originated from solvent-triggered intermediates, which were determined by UV-visible spectra from isolated enimine. The phenol-iminium E-A is dominant in water and the ketoenamine intermediate E-B is prevalent in acetonitrile. In the presence of pyrrolidine and oxygen, E-A leads to flavonol through E-I, a zwitterionic-like phenoloxyl-iminium ion, following the key steps of cyclization and a [2 + 2] oxidation; E-B proceeds through path II, a radical process induced by photolysis of E-B with both pyrrolidine and oxygen, to afford aurone. Preliminary mechanistic studies are reported.

A series of ZnCl2 complexes (compounds 1-10) with 4′-(substituted-phenyl)-2,2′:6′,2 ”-terpyridine that bears hydrogen (L-1), p-methyl (L-2), p-methoxy (L-3), p-phenyl (L-4), p-tolyl (L-5), p-hydroxyl (L-6), m-hydroxyl (L-7), o-hydroxyl (L-8), p-carboxyl (L-9), or p-methylsulfonyl (L-10) were prepared and then characterized by H-1 NMR, electrospray mass-spectra (ESI-MS), IR, elemental analysis, and single crystal X-ray diffraction. In vitro cytotoxicity assay was used to monitor the antiproliferative activities against tumor cells. Absorption spectroscopy, fluorescence titration, circular dichroism spectroscopy, and molecular modeling studied the DNA interactions. All of the compounds display interesting photoluminescent properties and different maximal emission peaks due to the difference of the substituent groups. The cell viability studies indicate that the compounds have excellent antiproliferative activity against four human carcinoma cell lines, A549, Bel-7402, MCF-7, and Eca-109, with the lowest IC50 values of 0.33 (10), 0.66 (6), 0.37 (7), and 1.05 (7) mu M, respectively. The spectrophotometric results reveal that the compounds have strong affinity binding with DNA as intercalator and induce DNA conformational transition. Molecular docking studies indicate that the binding is contributed by the pi…pi stacking and hydrogen bonds, providing an order of nucleotide sequence binding selectivity as ATGC > ATAT > GCGC. These compounds intercalate into the base pairs of the DNA of the tumor cells to affect their replication and transcription, and the process is supposed to play an important role in the anticancer mechanism.

This study describes the latest generation of a high-throughput screening system that is capable of screening thousands of organic reactions in a single day. This system combines a liquid handling robot with desorption electrospray ionization (DESI) mass spectrometry (MS) for a rapid reaction mixture preparation, accelerated synthesis, and automated MS analysis. A total of 3840 unique reductive amination reactions were screened to demonstrate the throughputs that are capable with the system. Products, byproducts, and intermediates were all monitored in full-scan mass spectra, generating a complete view of the reaction progress. Tandem mass spectrometry experiments were conducted to verify the identity of the products formed. The amine and electrophile reactivity trends represented in the data match what is expected from theory, indicating that the system accurately models the reaction performance. The DESI results correlated well with those generated using more traditional mass spectrometry techniques like liquid chromatography-mass spectrometry, validating the data generated by the system.

Self-assembled peptide nanofibers have attracted extensive attention; they offer unique templating possibilities, which allow the synthesis of nanostructured materials with high surface areas, and also act as organocatalysts for various transformations in organic chemistry. In the present work, peptide nanofibers as hydrogen-bonding organocatalysts have been developed as efficient organocatalysts for three-component Groebke condensation reactions of aldehydes, isocyanides, and 2-aminopyridines in PEG to afford the corresponding 3-aminoimidazo [1, 2-a] pyridines in high yields without any additives. The key advantages of catalytic systems are (1) using peptide nanofibers as powerful hydrogen-bonding organocatalysts for the synthesis of 3-aminoimidazo [1, 2-a] pyridines, (2) having high catalytic activity, and (3) performing the reactions which can be carried out in PEG, as green solvent instead of the usually used organic solvents. This catalyst could be recycled and reused at least for four times without noteworthy loss of its activity. [GRAPHICS] .
