Background: The Epidermal Growth Factor Receptor (known as EGFR) induces cell differentiation and proliferation upon activation through the binding of its ligands. Since EGFR is thought to be involved in the development of cancer, the identification of new target inhibitors is the most viable approach, which recently gained momentum as a potential anticancer therapy. Objective: To assess various pyrazole linked pyrazoline derivatives with carbothioamide for EGFR kinase inhibitory as well as anti-proliferative activity against human cancer cell lines viz. A549 (non-small cell lung tumor), MCF-7 (breast cancer cell line), SiHa (cancerous tissues of the cervix uteri), and HCT-116 (colon cancer cell line). Methods: In vitro EGFR kinase assay, in vitro MTT assay, Lactate dehydrogenase release, nuclear staining (DAPI), and flow cytometry cell analysis. Results: Compounds 6h and 6j inhibited EGFR kinase at concentrations of 1.66 mu M and 1.9 mu M, respectively. Furthermore, compounds 6h and 6j showed the most potent anti-proliferative results against the A549 KRAS mutation cell line (IC50 = 9.3 & 10.2 mu M). Through DAPI staining and phase contrast microscopy, it was established that compounds 6h and 6j also induced apoptotic activity in A549 cells. This activity was further confirmed by FACS using Annexin-V-FITC and Propidium Iodide (PI) labeling. Molecular docking studies performed on 6h and 6j suggested that the compounds can bind to the hinge region of ATP binding site of EGFR tyrosine kinase in a similar pose as that of the standard drug gefitinib. Conclusion: The potential anticancer activity of compounds 6h and 6j was confirmed and need further exploration in cancer cell lines of different tissue origin and signaling pathways, as well as in animal models of cancer development.

Selective hydroxylation of different phenylboronic acids to phenols was successfully carried out by using Cu nanoparticles-enzyme hybrid catalysts in water and room temperature. Different Cu-enzyme hybrids containing Cu(II), Cu(I) and Cu(0) nanoparticles species respectively were tested on the monohydroxylation of phenylboronic acid under these mild conditions being hybrids containing Cu(0)NPs the best catalysts, with total selectivity and formation of phenol as unique product. Also, the addition of hydrogen peroxide or the increase of reaction temperature were tested but did not improved these results. The substrate scope was also demonstrated and the Cu(0)NPs hybrid showed excellent results in the monohydroxylation of differento-, m-, p-substituted phenylboronic acid with final yields >95 %. This catalyst showed excellent recyclability after 5 cycles of use.

This study examines the post-ingestive fate of two host-plant derived small-molecule phenolics (the acetophenones piceol and pungenol) that have previously been shown to be toxic to the outbreaking forest pest, spruce budworm (Choristoneura fumiferana). We test first whether these compounds are transformed during passage through the midgut, and second whether the budworm upregulates activity of the detoxification enzyme glutathione-s-transferase (GST) in response to feeding on these compounds. Insects were reared on either foliage or artificial diet to the fourth instar, when they were transferred individually to one of two treatment diets, either control or phenolic-laced, for approximately 10 days, after which midguts were dissected out and used for Bradford soluble protein and GST enzyme activity analysis. Frass was collected and subjected to HPLC-DAD-MS. HPLC showed that the acetophenones do not autoxidize under midgut pH conditions, but that glucose- and glutathione-conjugates are present in the frass of insects fed the phenolic-laced diet. GST enzyme activity increases in insects fed the phenolic-laced diet, in both neutral pH and alkaline assays. These data show that the spruce budwom exhibits counter-adaptations to plant phenolics similar to those seen in angiosperm feeders, upregulating an important detoxifying enzyme (GST) and partially conjugating these acetophenones prior to elimination, but that these counter-measures are not totally effective at mitigating toxic effects of the ingested compounds in the context of our artifical-diet based laboratory experiment.

In biorefineries, renewable resources are converted to value-added chemicals. However, lignin is often only thermally valorized. In this work, we propose an integrated process where lignin is extracted from beech wood by a thermal autoclave pretreatment in a hydrotropic solution. With increasing pretreatment temperature, we find a rising lignin recovery of dose to 90% at 200 degrees C. Subsequently, the hydrotropic solution enables a homogeneous Fenton process as lignin can be dissolved at acidic pH values. While lignin is degraded, we demonstrate a feasible in situ extraction of low-molecular-weight aromatics such as p-cumenol. The proposed process proves to be a viable source for valuable compounds, with up to 30% yield of organic acids based on the initial lignin concentration. Consequently, the integrated process described herein encompasses resource efficiency, as only one solvent is used for pretreatment and degradation, and raw material efficiency with a lignin extraction yield close to 90%.

A water-mediated MCR strategy has been developed for the synthesis of donor (D)-acceptor(A) type hydrazinyl thiazolyl coumarins (HTCs) (4) in excellent isolated yields (90-98%) from a three component reaction of aromatic aldehydes/ketones (1), thiosemicarbazide (2) and 3-(2-bromoacetyl)-2H-chromen-2-one (3) catalyzed by an environmentally compatible montmorillonite (MMT) K10 clay at RT for 20-40 min. The present MCR strategy has several advantages that include its wide-spread substrate scope, eco-compatibility, short reaction times and products that do not require chromatographic purification. Besides, the method is simple to perform, it is easy to construct C-N, C=N and C-S bonds in one pot and the reaction can be scaled up to a gram level. Moreover, the catalyst can be reused 7 times without significant change of activity. The photophysical properties of the synthesized D-A type HTCs are also studied and it was noticed that the fluorescence properties can be varied with the position of electron donating group on the aromatic ring of aldehyde/ketone of HTCs. Most of the compounds exhibited bright fluorescence in chloroform (1.0 x 10(-5) M) with emission maxima ranging from 409 to 511 nm and large Stokes shifts. Further, the HOMO and LUMO energy levels of the HTCs are found in the range from -5.65 eV to -5.22 eV and -2.67 eV to -2.17 eV, respectively, and in good agreement with the reported hole transporting materials.

The conversion of aldehydes and ketones to 1 degrees amines could be promoted by half-sandwich iridium complexes using ammonium formate as both the nitrogen and hydride source. To optimize this method for green chemical synthesis, we tested various carbonyl substrates in common polar solvents at physiological temperature (37 degrees C) and ambient pressure. We found that in methanol, excellent selectivity for the amine over alcohol/amide products could be achieved for a broad assortment of carbonyl-containing compounds. In aqueous media, selective reduction of carbonyls to 1 degrees amines was achieved in the absence of acids. Unfortunately, at Ir catalyst concentrations of <1 mM in water, reductive amination efficiency dropped significantly, which suggest that this catalytic methodology might be not suitable for aqueous applications where very low catalyst concentration is required (e.g., inside living cells).

Safety of 4′-Hydroxyacetophenone. I found the field of Chemistry; Physics very interesting. Saw the article Unveiled understanding on corrosion inhibition mechanisms of hydrazone derivatives based on naproxen for mild steel in HCl: A joint experimental/theoretical study published in 2020.0, Reprint Addresses Lgaz, H; Chung, IM (corresponding author), Kirkuk Univ, Coll Educ, Dept Chem, Kirkuk, Iraq.. The CAS is 99-93-4. Through research, I have a further understanding and discovery of 4′-Hydroxyacetophenone.

The current investigation seeks to explore the adsorption mechanism of newly synthesized Naproxen-based hydrazones on mild steel (MS) surface in 1.0 M HCI solution and their corrosion inhibition efficiencies. To this end, two hydrazone derivatives namely, (E)-N’-(1-(4-chlorophenypethylidene)-2-(6-methoxynaphthalen-2-yl)propanehydrazide (PHD-Cl) and (E)-N’-(1-(4-hydroxyphenypethylidene)-2-(6-methoxynaphthalen-2-yl) propanehydrazide (PHD-OH) were synthesized, characterized and their corrosion inhibition effects were evaluated using a combined electrochemical and theoretical approach. It is evidently dear from the findings presented in this investigation that the two inhibitors exhibited excellent protection efficiency, and the best inhibition performance was shown by PHD-OH inhibitor (96% at 5 x 10(-3) M ). Weight loss measurements revealed that the optimum concentration of inhibitors is 5 x 10(-3) mol/L. The experimental results obtained by electrochemical techniques (potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS)) indicated that the presence of PHD-CI and PHD-OH compounds greatly increased the polarization resistance and affected both anodic and cathodic reactions, i.e. mixed-type inhibitors. Based on electrochemical results, the polarization resistance was greatly increased, from an initial value for the MS (in 1.0 moll HCI) of 29 up to 871 Omega cm(2) for the inhibited solution (1.0 mol/L HCl with 5 x 10(-3) mol/L. of PHD-OH). Furthermore, the adsorption isotherm coincides well with the Langmuir isotherm model. The effect of temperature on PHD-OH adsorption was investigated, experimentally using weight loss tests, and theoretically using molecular dynamic simulations (MD). Moreover, the study found that a protective barrier was set up through the adsorption of the studied compounds on MS surface which is confirmed by scanning electron microscopy with energy-dispersive X-ray analysis (SEM-EDX). Moreover, molecular proprieties of corrosion inhibitor molecules were explored from a theoretical viewpoint using Density Functional Theory (DFT), molecular dynamic (MD) simulation and radial distribution function (RDF) studies. Theoretical results that were in good agreement with experimental findings demonstrated strong interactions between inhibitor molecules and metal surface. (C) 2020 Elsevier B.V. All rights reserved.

Isoxsuprine (ISX) is widely used for cerebral and peripheral vascular diseases. A comparative study was held among different multivariate calibration models for selective determination of a complex mixture of Isoxsuprine and four of its toxic photothermal degradation products that impair kidney and liver functions. The Partial Least Squares (PLS) and Artificial Neural Network (ANN) models were applied on the specific spectrum and on selected wavelengths using genetic algorithm (GA) technique as an efficient variable selection tool. The effect of GA on the model construction and performance was evaluated. The multilevel multifactor experimental design was adopted for the construction of the calibration set. Optimized parameters were used for the development of the different models. The performances of the developed models were assessed by predicting the concentration of eight different mixtures composing the validation set. Results were compared to one another and to the official method using one-way ANOVA statistical test to assure the validity of the constructed models. The lower chance of overfitting offered by ANN minimized the RMS EP relative to the PIS. On the other hand, the application of GA prior to model implementation affected the number of latent variables the prediction ability of both PIS and ANN models. The validated models were successfully applied as stability indicating assay methods for the selective determination of ISX and its photothermal degradation products in ISX raw material and market formulations.
