Chromatographic separation of the extracts of the Australian rainforest plant Ternstroemia cherryi led to the isolation of five undescribed barrigenol-like triterpenoids, ternstroenols A – E, from the fruits and three known ones from the leaves. Ternstroenols A – E represent a new form of structural diversity, being the first in its kind to incorporate a trans- 2, 4, 6- decatrienoyl moiety at C-22. The structures of the ternstroenols were assigned by detailed spectroscopic analysis, degradation and chemical derivatization. All compounds exhibited potent antiinflammatory activity in LPS and IFN-gamma activated RAW 264.7 macrophages, with IC50, values as low as 0.7 mu M. Despite the remarkable potency, high levels of unwanted cell growth inhibition was also observed, which prompted their cytotoxic evaluation in U87/U251 human glioblastoma cell lines.

Formulation of delivery systems for active ingredients is of increasing importance for the food industry. For that purpose, we selected cellulose as a carrier polymer of raspberry volatiles. Freeze-dried cellulose/raspberry complexes were prepared by complexation of raspberry juice (constant amount) and cellulose (2.5%, 5%, 7.5% and 10%). In our study, cellulose was shown as a good carrier of raspberry juice volatiles. Thirty-nine volatiles were detected in raspberry juice while 11 of them were lost during preparation of the complexes. Berry flavor note was the dominant one in raspberry juice (40% of overall flavor), followed by citrus and woody notes (each around 18% of overall flavor) and floral, fruity, and green (each around 8% of overall flavor). Cellulose/raspberry complexes had different flavor profiles, but a berry flavor note was still the dominant one in all complexes. These results suggest an efficient plant-based approach to produce value-added cellulose/volatile dry complexes with possible utility as food flavoring ingredients.

Recommanded Product: 4-Methoxybenzaldehyde. I found the field of Chemistry very interesting. Saw the article Nano-pistachio hull-OSO3H: synthesis, characterization and application as an effective and novel nanocatalyst for one-pot synthesis of dihydropyrano [3, 2-b] chromene dione derivatives published in 2021, Reprint Addresses Sadeghi, B (corresponding author), Islamic Azad Univ, Yazd Branch, Dept Chem, Yazd, Iran.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde.

In this work, the novel pistachio hull-OSO3H catalyst was synthesized via preparing pistachio hull as a support followed by treatment with chlorosulfonic acid (ClSO3H) and identified by Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FE-SEM), X-ray diffraction spectroscopy (EDX), Thermogravimetric analysis (TG) and X-ray powder diffraction (XRD). The size of the pistachio hull-OSO3H nanocatalyst was shown by a scanning electron microscope below 100 nm. The catalytic activity of the solid acid catalyst has been successfully examined in a one-pot, three-component condensation reaction of aromatic aldehydes, dimedone and kojic acid under solvent-free condition to furnish dihydropyrano [3,2-b] chromen dione derivatives. The proposed approach has some advantages as excellent yields, mild reaction conditions, short reaction times, use of agricultural waste and eco-friendly nature.

The photocatalytic behavior of the graphene oxide (GO) modified Fe(III)/peroxymonosulfate (Fe/PMS) system for bisphenol A (BPA) degradation was investigated. With the addition of GO, a dramatic enhancement of BPA degradation was obtained at pH 3.0 under visible light irradiation. According to ESR analysis and quenching tests, both SO4 center dot- and center dot OH are responsible for BPA degradation. The characterization analysis demonstrates that Fe(III) can chelate with the oxygenic functional groups on the surface of GO forming a stable GO-Fe(III) complex. The detections of different kinds of Fe species reveal that Fe(III) can be reduced to Fe(II) by GO via intramolecular electron transfer in the GO-Fe(III) complex, and visible light could enhance this process. The Fe(III)/Fe(II) cycle not only occurs on the surface of GO, but also in aqueous solution via homogeneous reactions. In addition, the degradation pathway of BPA was proposed based on the identification of the intermediates using GC-MS and LC-MS techniques. (C) 2020 Elsevier Inc. All rights reserved.

Name: 4-Methoxybenzaldehyde. I found the field of Chemistry; Physics very interesting. Saw the article Verification of corrosion inhibition of Mild steel by some 4-Aminoantipyrine-based Schiff bases – Impact of adsorbate substituent and cross-conjugation published in 2021.0, Reprint Addresses Kar, PK (corresponding author), Veer Surendra Sai Univ Technol, Dept Chem, Burla 768018, India.. The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde.

Corrosion inhibition of mild steel (MS) by a series of 4-aminoantipyrine-based Schiff base has been studied in 1 N HCl aqueous medium adopting electrochemical method at different concentration (10(-2)-10(-5) M) and temperature (303-333 K). All of the inhibitors were found to be dominated by cathodic/anodic in nature (mixed type). Electrochemical impedence and polarization studies were in agreement with each other. The surface morphology (smoothness and roughness) was characterized by SEM, which indicates the formation of protective layer on the MS surface. The substituents on the Schiff bases influence their corrosion inhibition properties. Schiff bases having -OCH3, -OH and -NMe2 substituents exhibit more inhibition tendency as compared to other substituents. The role of cross conjugation in electron donating as well as accepting properties by heteroatom (N, O) and pi-electrons in corrosion inhibition was clearly observed from DFT calculations. Monolayer formation on the MS surface has been confirmed from the Langmuir isotherm fitting. Thermodynamic modeling has been done to understand the nature of adsorption. The values of Delta G (>-30 kJ/mol/K) indicate the existence of both physical and chemical interactions between the Schiff base molecules and metal surface. (C) 2021 Elsevier B.V.

The new complex [Zn(im)(4)](NO3)(2) (1) was synthesized and crystallographically characterized. In the solid state, 1 is built up by [Zn(C3H4N2)](2+) cations and NO3- anions interlinked by N-H center dot center dot center dot O hydrogen bonds which give rise to the formation of a 3D network. Complex 1 and [CdNa2(mu-L-2)](n)center dot 6.34H(2)O (2), (L=2-(2-(4,4-dimethyl-2,6-dioxocyclohexylidene) hydrazinyl)terephthalate) were used as catalysts for the Henry reaction, and high yields were obtained under optimum conditions. Both 1 and 2 act as very efficient catalysts for the Henry reaction and convert nitroethane and aldehydes to beta-nitroalcohols in yields of up to 89%. The threo/erythro diastereoselectivity depends on the choice of catalyst and also the selection of the reaction substrate, reaching values up to 89:11. (C) 2018 Elsevier Ltd. All rights reserved.

In this study, Co3O4 nanocatalysts were constructed in environmentally appropriate conditions using controlled, effective, and facile microwave method. The final nanostructures were characterized by SEM, XRD, and TEM analyses. The products had a small size distribution, homogeneous morphology, and crystallographic structures associated with the formation of Co3O4 nanostructures. Moreover, EDS mapping analysis confirmed the existence of Co and O elements in the final structure, and the magnetic properties of the samples were investigated by VSM. The application of this nanostructure in a catalytic process was further examined, and the results suggested that it could be used as a novel candidate for the synthesis of arylidene barbituric and Meldrum(,)s acid through Knoevenagel condensation of aldehydes by barbituric and Meldrum(,)s acid in aqueous media. The high yield of these nanocatalysts would be justified by the nature of the nanostructure as well as the experimental procedure developed in this study, which affected the physicochemical features of the products.

Background: In continuation of our work, new diazenyl chalcones scaffolds (C-18 to C-27) were efficiently synthesized from substituted acetophenone azo dyes (A-E) by base catalyzed Claisen-Schmidt condensation with different substituted aromatic/heteroaromatic aldehydes. Methodology: The synthesized chalcones were assessed for their in vitro antimicrobial potential towards several pathogenic microbial strains by tube dilution method and further evaluated for antioxidant potential by DPPH assay. These derivatives were also assessed for the cytotoxicity towards the human lung cancer cell line (A549) and normal cell line (HEK) by MTT assay. The most active antimicrobial compounds were docked using Schrodinger v18.1 software with the various potential bacterial receptors to explore the mechanism of interaction. Results: The derivative C-22 exhibited high antibacterial activity with very low MIC (1.95-3.90 mu g ml(-1)) and MBC (3.90-7.81 mu g ml(-1)) values. The derivatives C-23, C-24 and C-27 have demonstrated good antioxidant potential (IC50 = 7-18 mu g ml(-1)) correlated to the ascorbic acid (IC50 = 4.45 mu g ml(-1)). The derivative C-25 had shown comparable cytotoxicity to camptothecin against A549 cell line. The docking studies predicted the bacterial dihydrofolate reductase (PDB ID: 3SRW) and bacterial DNA gyrase (PDB ID: 4ZVI) as the possible targets for most of the active antimicrobial compounds. These derivatives affirmed their safety by presenting less cytotoxicity towards HEK cells. Further the ADME prediction by qikprop module of the Schrodinger proved that these compounds exhibited drug-like attributes. Conclusion: Hence, these compounds have shown their potential as lead for future expansion of novel antimicrobial and cytotoxic drugs.
