Quality Control of Benzyl Alcohol. I found the field of Chemistry; Physics very interesting. Saw the article Aloysia citrodora leaves extract corrosion retardation effect on mild-steel in acidic solution: Molecular/atomic scales and electrochemical explorations published in 2020.0, Reprint Addresses Bahlakeh, G (corresponding author), Golestan Univ, Fac Engn, Dept Chem Engn, Aliabad Katoul, Iran.; Ramezanzadeh, B (corresponding author), Inst Color Sci & Technol, Dept Surface Coatings & Corros, POB 16765-654, Tehran, Iran.. The CAS is 100-51-6. Through research, I have a further understanding and discovery of Benzyl Alcohol.

In the present research, the aqueous-extract of Aloysia citrodora leaves (Ac.L) was chosen as mild steel (MS) inhibitor against 1 M HCl medium. Electrochemical impedance spectroscopy (EIS) outcomes demonstrated that in the presence of 800 ppm Ac.L extract, and at immersion time of 2.5 h the MS corrosion was noticeably retarded by 94% inhibition degree. The kinetics of corrosion retardation were inspected by polarization studies, and the respective achievements declared that the Aloysia citrodora leaves extract constituents could retard corrosion reactions via cathodic/anodic (mixed) inhibition mechanism. The surface investigation results proved the effectiveness of Aloysia citrodora leaves extracts in MS surface damage retardation. Alongside the electrochemical/surface studies, comprehensive theoretical explorations utilizing Monte Carlo (MC)/molecular dynamics (MD) and quantum chemical computations of density functional theory (DFT) ensured the phytochemicals binding on target metallic substrate.

An efficient amino-acid-mediated ipso-hydroxylation of arylboronic acids, aryl boronate esters and aryl trifluoroborates to aryl alcohols has been described. The current protocol was realized by using sub-stoichiometric amount of l-histidine in presence of triethylamine under aerobic conditions in DMF as solvent. This amino-acid-mediated process provides an alternative route for the hydroxylation of organoborons through in situ generation of hydrogen peroxide. The present protocol explores the synthetic utility of amino acids as organocatalysts for the preparation of aryl alcohols. It was observed that l-histidine plays an important role for the conversion of aerial oxygen in to hydrogen peroxide via thermal excitation process followed by thermal degradation of Et3N. The developed approach holds good for a wide range of compounds with excellent yields and competent functional group tolerance.

Chromenes and their derivatives are an important class of compounds known for their biological properties. In this study, synthetic methodologies were described to obtain 4H-chromene derivatives. Two routes were investigated, the first being a bicomponent reaction using Knoevenagel adducts as reagents and the second using one-pot tricomponent reactions, both under microwave irradiation, using H2O as solvent and triethylamine as catalyst. Twenty 4H-chromene derivatives were synthesized with 50-95% yields from aromatic aldehydes, 5,5-dimethyl-1,3-cyclohexadione and malononitrile or methyl cyanoacetate, being further characterized by Fourier Transform Infrared and Nuclear Magnetic Resonance. We also report three crystal structures from the synthesized chromene derivatives, by single-crystal X-ray diffraction, showing the main supramolecular features of each structure – a poorly unexplored approach involving this class of compounds so far.

Approximately 60% of human cancers exhibit enhanced activity of ERK1 and ERK2, reflecting their multiple roles in tumor initiation and progression. Acquired drug resistance, especially mechanisms associated with the reactivation of the MAPK (RAF/MEK/ERK) pathway represent a major challenge to current treatments of melanoma and several other cancers. Recently, targeting ERK has evolved as a potentially attractive strategy to overcome this resistance. Herein, we report the design and synthesis of novel series of fused naphthofuro[3,2-c] quinoline-6,7,12-triones 3a-f and pyrano[3,2-c]quinoline-6,7,8,13-tetraones 5a,b and 6, as potential ERK inhibitors. New inhibitors were synthesized and identified by different spectroscopic techniques and X-ray crystallography. They were evaluated for their ability to inhibit ERK1/2 in an in vitro radioactive kinase assay. 3b and 6 inhibited ERK1 with IC50s of 0.5 and 0.19 mu M, and inhibited ERK2 with IC50s of 0.6 and 0.16 mu M respectively. Kinetic mechanism studies revealed that the inhibitors are ATP-competitive inhibitors where 6 inhibited ERK2 with a K-i of 0.09 mu M. Six of the new inhibitors were tested for their in vitro anticancer activity against the NCI-60 panel of tumor cell lines. Compound 3b and 6 were the most potent against most of the human tumor cell lines tested. Moreover, 3b and 6 inhibited the proliferation of the BRAF mutant A375 melanoma cells with IC50s of 3.7 and 0.13 mu M, respectively. In addition, they suppressed anchorage-dependent colony formation. Treatment of the A375 cell line with 3b and 6 inhibited the phosphorylation of ERK substrates p-90RSK and ELK-1 and induced apoptosis in a dose dependent manner. Finally, a molecular docking study showed the potential binding mode of 3b and 6 within the ATP catalytic binding site of ERK2.

We report here structural development of N-(4-phenoxyphenyl)benzamide derivatives as novel SPAK (STE20/ SPS1-related proline/alanine-rich kinase) inhibitors. Abnormal activation of the signal cascade of with-no-lysine kinase (WNK) with OSR1 (oxidative stress-responsive kinase 1)/SPAK and NCC (NaCl cotransporter) results in characteristic salt-sensitive hypertension, and therefore inhibitors of the WNK-OSR1/SPAK-NCC cascade are candidates for antihypertensive drugs. Based on the structure of lead compound 2, we examined the SAR of N-(4-phenoxyphenyl)benzamide derivatives, and developed compound 20l as a potent SPAK inhibitor. Compounds 20l is a promising candidate for a new class of antihypertensive drugs.

Leukocyte transendothelial migration is one of the most important step in launching an inflammatory immune response and chronic inflammation can lead to devastating diseases. Leukocyte migration inhibitors are considered as promising and potentially effective therapeutic agents to treat inflammatory and auto-immune disorders. In this study, based on previous trioxotetrahydropyrimidin based integrin inhibitors that suboptimally blocked leukocyte adhesion, twelve molecules with a modified scaffold were designed, synthesized, and tested in vitro for their capacity to block the transendothelial migration of immune cells. One of the molecules, namely, methyl 4-((2-(tert-butyl)-6-((2,4,6-trioxotetrahydropyrimidin-5(2H)-ylidene) methyl) phenoxy) methyl) benzoate, (compound 12), completely blocked leukocyte transendothelial migration, without any toxic effects on immune or endothelial cells (IC50 = 2.4 mu M). In vivo, compound 12 exhibited significant therapeutic effects in inflammatory bowel disease (IBD)/Crohn’s disease, multiple sclerosis, fatty liver disease, and rheumatoid arthritis models. A detailed acute and chronic toxicity profile of the lead compound in vivo did not reveal any toxic effects. Such a type of molecule might therefore provide a unique starting point for designing a novel class of leukocyte transmigration blocking agents with broad therapeutic applications in inflammatory and auto-immune pathologies.

For the first time, a one pot thermolysis of [Pd(PPh3)(2)Cl-2] prepared by reacting Ph3P with PdCl2 in a 2 : 1 molar ratio in MeOH at 280 degrees C in a trioctylphosphine (TOP) and oleylamine(OA)-octadecane(ODE) mixture (1 : 1) was used to prepare quantum dots (QDs; size similar to 2-3 nm) and nanoparticles (NPs; size similar to 13-14 nm), respectively, of composition Pd3P0.(95). TEM, SEM-EDX, powder-XRD and XPS (for QDs only) were used to authenticate the two nanophases. P-31{H-1}NMR experiments performed to monitor the progress of thermolysis reactions revealed that the phosphorus present in the Pd3P0.(95) QDs had come from TOP, whereas in Pd3P0.(95) NPs, its source is triphenylphosphine. The nature of the solvent did not affect the chemical composition of the nano-phase but controlled its size. Probably, solvent dependent, unique, single source precursors (SSPs) of palladium were generated in situ, and controlled the size. The catalytic activity of both Pd3P0.(95) QDs and NPs was explored. The QDs were found to be efficient as a catalyst for the amide-nitrile interconversion at room temperature (yield up to 92% in 4 h), hydration of nitriles and transfer hydrogenation (TH) of carbonyl compounds with yields up to 96% in 3-4 h. The yields and reaction rates of amide-nitrile inter-conversion and TH when catalyzed by Pd3P0.95 QDs were found to be higher compared to the ones observed with the Pd/C catalyst. The binding energy of Pd(3d) in the X-ray photoelectron spectrum (XPS) of Pd3P0.95 indicated an electron transfer from the metal to phosphorus, resulting in electron deficient palladium, which facilitates the coordination of a substrate to Pd and drives the reaction. The reusability of Pd3P0.(95) QDs for the interconversion was found to be up to 4-times, while for the transfer hydrogenation of carbonyl compounds it was up to 6-times, but with a diminished yield. Pd3P0.(95) NPs were found to be less active (yield up to 36% in optimized reaction conditions) in comparison to Pd3P0.(95) QDs. The mercury poisoning test suggested that the catalysis predominantly proceeded heterogeneously on the surface of the QDs. The PXRD and XPS results did not suggest a significant variation in the phase of QDs after the third catalytic cycle. The bleeding of Pd during catalysis (determined by flame AAS) and the agglomeration of QDs as supported by the SEM-EDX and TEM results are probably responsible for the reduction in the catalytic activity of QDs after reusing three times.

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.
