Benzothiazolyl substituted spiropyrans with ion-driven photochromic transformation

The present work is devoted to the synthesis and detailed investigation of new 8-benzothiazole containing spiropyrans. The investigated spiropyrans exist under colorless spirocyclic isomers exhibiting positive photochromism with thermo- and photoinduced back reaction. UV light irradiation leads to their effective coloration with quantum yields up to 44%. The efficiency of the back photocyclization induced by visible light does not exceed 0.1%. This feature distinguishes them from the previously studied benzoxazole analogs. The enhancement of electron-withdrawing properties of the indoline fragment substituents promotes an increase in photo-coloration efficiency. The lifetime of the colored form varies from 17 to 200.8 s (acetone, 293 K) depending on substituents. Due to the presence of the benzothiazole moiety, merocyanines can effectively bind Zn2+, Co2+, Ni2+, Cu2+, Cd2+, Mn2+ ions. The addition of salts of these ions to spiropyran solutions results in the stabilization of the merocyanine in the form of intensely colored complexes. Composition, stability and spectroscopic characteristics of complexes have been investigated depending on the metal ion nature and substituents in ligand molecules. The colored complexes possess negative photochromism. The visible light irradiation causes their bleaching with quantum yields up to 48%. The benzothiazole substituted spimpyrans demonstrate ion driving photochromic transformation.

Immunomodulatory and immunostimulatory effects of some bisbenzoxazole derivatives on lipopolysaccharide stimulated mammalian macrophages

Benzoxazoles and their derivatives have exerted anti-cancer and anti-inflammatory (immunomodulatory) potential due to their anti-proliferative effect on the cells. These molecules are DNA basebioisosteres, therefore, their mechanism of action could be by mimicking the structures of the DNA bases and halting the DNA polymerization processes. Based on their anti-proliferative effect, in our study we aimed to decipher the potential anti-inflammatory activities of unique bisbenzoxazole derivatives in vitro on mammalian macrophages. Being able to manipulate the inflammatory function of macrophages would enable the regulation of the immune response against danger stimuli. This would enable us better prognosis against different types of the diseases ranging from autoimmune disorders to cancer. Our results support the stark anti-inflammatory potential of bisbenzoxazole derivatives RHE 241 and RHE 248 in vitro on the LPS activated mammalian macrophages. After further delineation of their mechanism of action in vitro and their in vivo potency, these molecules could be utilized as potent anti-inflammatory medicines.

Discovery of 6-Arylurea-2-arylbenzoxazole and 6-Arylurea-2-arylbenzimidazole Derivatives as Angiogenesis Inhibitors: Design, Synthesis and in vitro Biological Evaluation

We embarked on a structural optimization campaign aimed at the discovery of novel anti-angiogenesis agents with previously reported imidazole kinase inhibitors as a lead compound. A library of 29 compounds was synthesized. Several title compounds exhibited selective inhibitory activities against vascular endothelial growth factor receptor 2 (VEGFR-2) over epidermal growth factor receptor (EGFR) kinase; these compounds also displayed selective and potent antiproliferative activity against three cancer cell lines. The newly synthesized compounds were evaluated for anti-angiogenesis activity by chick chorioallantoic membrane (CAM) assay. Among them, 1-(2-(2-chlorophenyl)benzo[d]oxazol-5-yl)-3-(4-(trifluoromethoxy)phenyl)urea (compound 5 n) showed the most potent anti-angiogenesis capacity, efficient cytotoxic activities (in vitro against human umbilical vein endothelial cells (HUVEC), H1975, A549, and HeLa cell lines, with respective IC50 values of 8.46, 1.40, 7.61, and 0.28 mu m), and an acceptable level of VEGFR-2 kinase inhibition (IC50=0.25 mu m). Molecular docking analysis revealed 5 n to be a type II inhibitor of VEGFR-2 kinase. In general, these results indicate that these 6-arylurea-2-arylbenzoxazole/benzimidazole derivatives are promising inhibitors of VEGFR-2 kinase for potential development into anti-angiogenesis drugs.

Dye-doped starch microparticles as a novel fluorescent agent for the visualization of latent fingermarks on porous and non-porous substrates

Detection and visualization of latent fingermarks are research areas that have been extensively explored over the years, mainly in the search for new methods and to improve existing fingermark developers. The aim of the present study was to propose new fingermark developers in an attempt to improve existing methods, especially regarding characteristics such as sensitivity, selectivity and ease of visualization on various substrates. In addition, we looked for developers that are cheaper, more environmentally friendly and less harmful to the health of those who handle them often. For this, the formulation of the proposed fluorescent developers was based on starch, a natural and high abundant polymer matrix. The small amount of organic dye incorporated into this matrix considerably reduces any risk of inherent toxicity. The high photophysical stability of the novel developer due to the use of embedded dyes that exhibit the excited-state infra-molecular proton transfer (ESIPT) mechanism and a high Stokes shift confer important and relevant optical properties. The influence of fingermark age and sequential deposition were studied. The results of the present study show that these novel developers are efficient and promising, especially for detecting fresh and non-fresh fingermarks on porous and non-porous substrates. Furthermore, the high photophysical stability of these fluorescent microparticles allow for preserving developed prints for a long time without degradation (important for the chain of custody).

Excited-state intramolecular proton transfer reactions of 2,5-bis(2′-benzoxazolyl)hydroquinone and its water cluster exhibiting single and double proton transfer: A TD-DFT dynamics simulation

Detailed pictures of the excited-state intramolecular proton transfer (ESIPT) of 2,5-bis(2′-benzoxazolyl)hydroquinone (BHQ) and its water cluster have been investigated by dynamics simulations on the first lowest excited energy using time-dependent density functional theory (TD-DFT). We focused on the structural, photophysical and dynamic properties of BHQin the absence and presence of water molecules through intermolecular hydrogen bonds (interHBs). Our dynamics simulations reveal three possible mechanisms of the ESIPT processes: i) no proton transfer (No PT); ii) single PT (SPT); and iii) double PT (DPT), that could take place within the PT time of 160 fs via intrinsic intramolecular hydrogen bonds (intraHBs). The ESIPT mechanism of isolated BHQ elucidates that back PT is likely to be found at 64% rather than the SPT (32%) and DPT (4%), which is in good agreement with the experiments of dual fluorescence from di-enol and mono-keto emissions. Notably, the results from BHQ with water (BHQ-(H20)2) reveal that the participation of water might produce a remarkable effect on promoting the SPT process up to 60% and DPI up to 7 times when compared to conditions of no water. The simulated probability of PT is well related to possible PT mechanisms regarding different tautomers in the fluorescence spectra found in previous experiments. The existence of di-keto tautomer arose from the DM’ of BHQ and its water cluster and was not observed in the UV/Vis spectrum. (C) 2019 Elsevier B.V. All rights reserved.

Expanding Benzoxazole-Based Inosine 5′-Monophosphate Dehydrogenase (IMPDH) Inhibitor Structure-Activity As Potential Antituberculosis Agents

New drugs and molecular targets are urgently needed to address the emergence and spread of drug-resistant tuberculosis. Mycobacterium tuberculosis (Mtb) inosine 5′-monophosphate dehydrogenase 2 (MtbIMPDH2) is a promising yet controversial potential target. The inhibition of MtbIMPDH2 blocks the biosynthesis of guanine nucleotides, but high concentrations of guanine can potentially rescue the bacteria. Herein we describe an expansion of the structure activity relationship (SAR) for the benzoxazole series of MtbIMPDH2 inhibitors and demonstrate that minimum inhibitory concentrations (MIC) of <= 1 mu M can be achieved. The antibacterial activity of the most promising compound, 17b (Q151), is derived from the inhibition of MtbIMPDH2 as demonstrated by conditional knockdown and resistant strains. Importantly, guanine does not change the MIC of 17b, alleviating the concern that guanine salvage can protect Mtb in vivo. These findings suggest that MtbIMPDH2 is a vulnerable target for tuberculosis. Application of 637031-93-7, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 637031-93-7 is helpful to your research.

Potential-induced phase transition of benzoxazole-2-thiol, naphthaleneoxazole-2-thiol and anthraceneoxazole-2-thiol monolayers on gold electrodes

In the present work we report the electrochemical characterization of self-assembled monolayers (SAMs) of N, O-heteroaromatic thiols, namely benzoxazole-2-thiol (1), naphthaleneoxazole-2-thiol (2) and anthraceneoxazole-2-thiol (3) on polycrystalline gold electrodes. SAMs were formed by immersion of pre-treated gold electrodes into ethanolic solutions of the title compounds. The modified electrodes exhibited a decrease of electroactivity, as found by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), in comparison to bare electrodes according to the length of the aromatic p-system. In addition, reductive desorption experiments confirmed that of the three compounds, 3 formed the most stable SAMs in agreement with EIS measurements which revealed better blocking properties against the redox couple in a test electrolyte indicating a charge transfer determined behaviour in the case of longer molecules. The charge transfer resistances revealed a trend towards higher resistances in the case of 3. When performing EIS at various starting potentials and different electrolyte concentrations, it was found that at certain critical potentials (E-crit) a potential-induced structural change of the SAM occurred, with E-crit(1) > E-crit(2) > E-crit(3). In the case of SAMs of 3 the nature of this alteration was investigated via scanning tunnelling microscopy and found to presumably be caused by an order-disorder-transition. (C) 2018 Elsevier Ltd.

On the design of new europium heteroaromatic carboxylates for OLED application

The approach to the directed synthesis of lanthanide aromatic carboxylates – precursors to the electro-luminescent materials, – was proposed, namely the conjugation length increase and heteroatom introduction in the appropriate position in combination with the neutral ligand introduction. This resulted in the isolation of a series of new lanthanide complexes, among which the highest electrolurninescence efficiency was obtained for mixed-ligand europium benzothiazole-2-carboxylate with bathophenanthroline in a solution-processed OLED. The peculiarities of energy transfer processes allowed obtaining luminescence thermometer materials based on this system, which demontrated the sensitivity of 2.8%/K in the physiological range.
