Four dyes that belong to the group of hemicyanines and possess benzoxazole and benzothiazole moieties are synthesised and described. The spectroscopic properties of these compounds in 1-methyl-2-pyrrolidinone (MP) were studied. Synthesised dyes absorb in the UV-Vis region. The emission spectra are broad with a maximum located at approximately 500-520 nm. The deactivation of excited states of the synthesised molecules by various quenchers is also presented. The fluorescence quenching parameters were calculated using the Stern-Volmer equation. It was found, that the fluorescence quenching of the excited dye by quencher molecules occurs. The fluorescence quenching rates (k(q)) are about 10(10) M-1 x s(-1). (C) 2020 Elsevier B.V. All rights reserved.

The present work investigates the kinetics of ligand substitution reaction and anticancer activities of the complexes, [{2-(2-pyridyl) benzimidazole} RuCl3] (C1), [{2-(2-pyridyl) benzoxazole} RuCl3] (C2), [{2-(2-pyridyl) benzothiazole} RuCl3] (C3) and [{1-propyl-2-(pyridin-2-yl)-H-benzoimidazole} RuCl3] (C4). The substitution kinetics reaction of the complexes with the three bio-relevant nucleophiles, viz.: thiourea (TU), 1, 3-dimethyl-2-thiourea (DMTU) and 1, 1, 3, 3-tetramethyl-2-thiourea (TMTU) was investigated under pseudo first-order conditions as a function of concentration and temperature using UV-Visible spectrophotometer. The substitution of the coordinated chloride was controlled by the electronic effect. The order of reactivity of the complexes with the nucleophiles is in the form C1 > C2 > C3 > C4 which is in line with the density functional theory (DFT) studies. The complexes showed minimal anticancer activity against the HeLa cell line, which is in contrast to the molecular docking experiments that exhibited stronger DNA binding affinities.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 372-38-3, in my other articles.

New research progress on 372-38-3 in 2021.Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. 372-38-3, Name is 1,3,5-Trifluorobenzene, molecular formula is , belongs to benzoxazole compound. In a document, author is Hu, Kun, Application In Synthesis of 1,3,5-Trifluorobenzene.

Six benzoxazole-terminated mesogenic compounds with fluoro substituent at different positions were prepared and their properties investigated. The compounds give a high birefringence (Delta n similar to 0.45) and a large-dielectric anisotropy (Delta epsilon similar to 26), indicating a possible application in liquid-crystal mixture as a dopant to enhance performance of the host mixture. In accordance with conventional high Delta n liquid crystals containing triple carbon-carbon bonds, lateral fluoro substituents and terminal groups can alter the Delta n and Delta epsilon of benzoxazole-terminated liquid crystals. Meanwhile, some parameters such as dipole moment, polarisability, dihedral angles are calculated with density functional theory (DFT) methods to relate to the experimental Delta n and Delta epsilon. It is noted that the introduction of the benzoxazole unit is an effective method to enhance Delta n and Delta epsilon values of the rodlike molecule, this is ascribed to its pi-conjugated benzene-fused heterocycle and large dipole moment.

The polycondensation of 5,5 -methylene bis(2-aminophenol) and the mixture of diamines 5,5 -methylene bis(2-aminophenol) and 4,4-(hexafluoroisopropylidene)dianiline (molar ratio 0.8:0.2) with isophthaloyl dichloride was used to synthesize a new heat resistant binder of the composites for microelectronics: poly(o-hydroxyamide) (POA) and poly(amido-o-hydroxy amide) (POA-F). The thermal stability of synthesized polymer coatings, as well as based on them photosensitive compositions with a naphthoquinondiazide photosensitive component were studied in the temperature range from 100 to 500 degrees C. Ferroelectric composites with nanodispersed lead titanate zirconate powder filler were formed based on these polymer matrices. By manipulating the conditions of the polymer formation, we obtained matrices with different stiffnesses, which reflected on the properties of the composite. The electrophysical parameters of the synthesized polymer and ferroelectric composite coatings were measured in the frequency range from 0.1 Hz to 1.5 GHz and the temperature range from 0 to 300 degrees C. The frequency and temperature stability of the dielectric constant of ferroelectric composite coatings up to 10 MHz and 300 degrees C, respectively, are noted. The influence of the composition and structure of the polymer matrix and the grain/matrix interfaces on the thermal stability of the dielectric parameters of composite films is estimated. The shift of the phase transition region toward higher temperatures in the composite structure, as well as the sufficient rigidity of the poly(benzoxazole) matrix, provide high temperature and frequency stability of the dielectric constant of the studied composites.

In this study, p-tert-butyl at position 2 and acetamide bridged 4-substituted piperazine/piperidine at position 5 bearing benzoxazole derivatives were evaluated for their in vitro inhibitory activity against AChE, BChE and Tyrosinase, which are important targets in reducing the adverse effects of Alzheimer’s disease. The most active 1 g inhibited the BChE at a concentration of 50 mu M by 54 +/- 0.75%. Molecular docking studies of the compounds against BChE (PDB: 4BDS) were performed with Schrodinger and AutoDock Vina and the results were compared. Schrodinger docking scores were found to be more consistent. Estimated ADME profiles and bioactivity scores of the compounds were calculated and found to be compatible with Lipinski and other limiting rules. Geometric optimization parameters, MEP analysis and HUMO and LUMO quantum parameters of the most active 1 g were calculated by using DFT/B3LYP theory and 6-311 G (d,p) base set and results was viewed.

Benzazole dyes have shown great potential for application in different fields of science due to their intense and stable photoluminescence properties, associated with high sensitivity. In this study, we developed and evaluated micro-structured fluorescent powders based on benzazole dyes for fingerprint detection on different types (porous and non-porous) and colors (dark, white, and multi-colored) of surfaces. The new micro-structured powders were obtained by embedding a small amount of benzazole dye into a silica matrix (1:100 and 1:300 mass ratio) using an aqueous solution or ethanol under ambient conditions. The photophysical properties were characterized by UV-vis absorption and fluorescence emission spectroscopy. To assess the efficiency of these proposed powders, comparisons were performed with commercially available black, white, and fluorescent powders (Sirchie (R)) for different types of surfaces. The developed micro-structured powders showed intense fluorescence emission in the blue-green region, and a sharp contrast with the fingerprint residues when exposed to long wavelengths of UV light (365 nm) was observed, producing distinct ridge details on all examined surfaces.

New kinds of heterocyclic mesogenic compounds containing benzoxazole, ethynyl, and laterally fluorinated phenyl groups, namely 2-[4-[2-[4-alkoxyphenyl]ethynyl]-2,3-difluorophenyl]benzoxazole derivatives (nPEDFPBx), are synthesized and evaluated. The compounds nPEDFPBx except nitro-substituted ones have enantiotropic nematic mesophases with mesophase ranges of 16-86 degrees C and 29-108 degrees C on heating and cooling, respectively. The results show that introduction of two lateral fluorine atoms into molecule results in enhanced nematic mesophase stability. Meanwhile, nPEDFPBx displays much higher birefringence (0.507-0.624) than common tolanebased liquid crystals, which is ascribed to its large pi-conjugated molecule composed of benzene, ethynyl, and benzoxazole mesogenic unit. The nPEDFPBx has a high potential to serve as a dopant for liquid crystal mixture. [GRAPHICS] .
