Fluorescence sensing response of zinc(II) and pyrophosphate ions by benzoxazole appended dipodal Schiff base

A novel benzoxazole appended dipodal Schiff base (BS) was synthesized and its sensing property was investigated. The receptor BS detected Zn2+ ions selectively by turn-on fluorescence among the wide range of metal ions in DMSO-H2O (1:9 v/v, 50 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) at pH 7.4. The different physicochemical parameters of BS-Zn2+ complex were investigated by UV-vis, photoluminescence, H-1 NMR titration and ESI-MS techniques. The limit of detection (LOD) and binding constant (K-b) of BS-Zn2+ complex have been determined by fluorescence titration and found to be 4.53 x 10(4) M-1 and 0.52 mu M. Moreover, binding ratio of BS and Zn2+ was found to be 1:1 by Job’s method. Further, the BS-Zn2+ complex was used to sense pyrophosphate (PPi) ions as a secondary sensor in HEPES buffer solution. Overall, the sensitive fluorescence behavior of the receptor BS has been utilized as a powerful tracker for zinc ion and pyrophosphate ion in biological systems.

Investigation of thermal and fluorescent properties of benzoxazole-linked triphenylamine-based co-polyimides

A series of novel fluorescent co-polyimides are obtained by combining N (1)-(4-aminophenyl)-N (1)-(4-(benzo[d]oxazol-2-yl) phenyl) benzene-1,4-diamine and 4,4 ‘-oxydianiline with four aromatic anhydride, 3,3 ‘,4,4 ‘-benzophenonetetracarboxylic dianhydride, pyromellitic dianhydride, 4,4 ‘-oxydiphthalic anhydride, and 4,4 ‘-(hexafluoroisopropylidene)diphthalic anhydride following conventional polycondensation method. The resultant co-polyimides are characterized by elemental, Fourier transform infrared spectral analysis and gel permeation chromatography. All newly prepared polyimides (PIs) exhibit shallow highest occupied molecular orbital energy levels in the range of -4.47 to -4.98 eV and have reasonable optical bandgaps. The photoluminescence spectral analysis shows blue to green emission in solution form. Thermal and solubility properties reveal that the PIs with pendant 4-(benzo[d]oxazol-2-yl group linked to triphenylamine unit in polymer backbone impart not only good thermal stability but also appreciable solubility making these new co-polyimides versatile for multipurpose usage.

Direct synthesis of poly(benzoxazine imide) from an ortho-benzoxazine: its thermal conversion to highly cross-linked polybenzoxazole and blending with poly(4-vinylphenol)

This paper describes a facile one-pot synthesis of a poly(benzoxazine imide), NDOPoda Bz, through the reaction of a difunctional naphthalene dianhydride ortho-phenol (ND-ortho-phenol), paraformaldehyde, and 4,4′-oxydianiline in 1,4-dioxane, without the need for either the preparation of an amino-functionalized benzoxazine or subsequent thermal treatment. This new poly(benzoxazine imide) underwent cross-inking polymerization to form a highly cross-linked poly(benzoxazine imide), which, with additional thermal treatment, was converted to highly cross-linked polybenzoxazoles. A model monomer (NDOPa Bz) was also synthesized based on the reaction of ND-ortho-phenol with paraformaldehyde and aniline. Moreover, we investigated the blending of NDOPoda Bz with a poly(4-vinylphenol) (PVPh) homopolymer at various weight ratios to form miscible blend systems. Fourier transform infrared spectroscopy, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA) revealed the thermal stability and thermal curing behavior of these blends, which were miscible because of strong hydrogen bonds between the C=O groups of PNDOPoda BZ and the OH groups of PVPh. The DSC and TGA data suggested that these hydrogen bonds enhanced the glass transition temperatures, thermal stability, and char yields of the blends. In addition, this approach decreased the temperature for ring opening of the benzoxazine, accelerated the rate of benzoxazole ring formation of NDOPda Bz at a lower temperature, and improved the thermal stability of the formed polybenzoxazoles.

Synthesis of Various 2-Aminobenzoxazoles: The Study of Cyclization and Smiles Rearrangement

This study reports two synthetic approaches leading to 2-aminobenzoxazoles and their N-substituted analogues. Our first synthetic strategy involves a reaction between various o-aminophenols and N-cyano-N-phenyl-p-toluenesulfonamide as a nonhazardous electrophilic cyanating agent in the presence of Lewis acid. The second synthetic approach uses the Smiles rearrangement upon activation of benzoxazole-2-thiol with chloroacetyl chloride. Both developed synthetic protocols are widely applicable, afford the desired aminobenzoxazoles in good to excellent yields, and use nontoxic and inexpensive starting material.

Liquid-crystalline behavior and thermal conductivity of vinyl polymers containing benzoxazole side groups

A series of methacrylamides containing benzoxazole (BO) mesogenic side groups and different lengths of alkyl units was synthesized in this study. A methacrylamide containing the n-dodecyl group was selected as a suitable monomer to obtain beneficial thermally conductive polymeric materials because of its sufficient solubility in toluene in the subsequent radical polymerization and because of its liquid crystallinity. This methacrylamide led to a highly soluble polymer with film-forming ability. The BO-containing polymethacrylamide also exhibited liquid-crystalline (LC) behavior during the heating and cooling processes. The cast film was kept at a slightly lower temperature than the clearing temperature and quenched to room temperature. This procedure afforded a film maintaining optical anisotropy at room temperature, implying that a frozen LC structure is maintained at room temperature. The quenched film also resulted in a significantly enhanced thermal conductivity (lambda = 0.60 W m(-1) K-1) without the aid of fillers and external fields, unlike the as-cast counterpart without optical anisotropy. A polyacrylate containing a flexible long alkylene (C-6) spacer between the main chains and a BO-containing mesogenic side group was also investigated. The polyacrylate exhibited LC behavior during the heating and cooling processes over wide ranges. The polyacrylate film quenched from an established temperature, which contains a frozen LC structure, also exhibited a significantly enhanced lambda value (0.63 W m(-1) K-1) without fillers and external fields. Thus, the BO-containing vinyl polymers studied in this work are promising candidates for novel heat-releasing materials. (c) 2020 Society of Chemical Industry

Benzoxazole Derivatives as Promising Antitubercular Agents

Tuberculosis (TB) is an infectious disease caused predominantly by bacillus Mycobacterium tuberculosis (MTB). The increasing prevalence of multidrug-resistant MTB necessitates the discovery and development of alternative drugs against tuberculosis with a new mechanism of action. Over the past years, several benzoxazole derivatives have been synthesized and screened for their biological activity. Interestingly, some of them had promising antitubercular activity. Despite that, none of the benzoxazole derivatives has entered the phase of the preclinical hit-to-lead optimization step in anti-TB research. In this review, we are summarizing recently published articles that evaluate the potency of benzoxazole heterocycle in the development of novel anti-TB agents and outlined the future aspects of this promising heterocycle.

Design, Synthesis, and Biological Activity of New &ITN&IT-(Phenylmethyl)-benzoxazol-2-thiones as Macrophage Migration Inhibitory Factor (MIF) Antagonists: Efficacies in Experimental Pulmonary Hypertension

Macrophage migration inhibitory factor (MIF) is a key pleiotropic mediator and a promising therapeutic target in cancer as well as in several inflammatory and cardiovascular diseases including pulmonary arterial hypertension (PAH). Here, a novel series of N-(phenylmethyl)-benzoxazol-2-thiones 5-32 designed to target the MIF tautomerase active site was synthesized and evaluated for its effects on cell survival. Investigation of structure-activity relationship (SAR) particularly at the 5-position of the benzoxazole core led to the identification of 31 that potently inhibits cell survival in DU-145 prostate cancer cells and pulmonary endothelial cells derived from patients with idiopathic PAH (iPAH-ECs), two cell lines for which survival is MIF-dependent. Molecular docking studies helped to interpret initial SAR related to MIF tautomerase inhibition and propose preferred binding mode for 31 within the MIF tautomerase active site. Interestingly, daily treatment with 31 started 2 weeks after a subcutaneous monocrotaline injection regressed established pulmonary hypertension in rats.

Excited-state intramolecular proton transfer (ESIPT) emitters based on a 2-(2-hydroxybenzofuranyl)benzoxazole (HBBO) scaffold functionalised with oligo(ethylene glycol) (OEG) chains

This article describes the multi-step synthesis of 2-(2-hydroxybenzofuran)benzoxazole (HBBO) derivatives functionalised with one to three oligo(ethylene glycol) (OEG) chains with the goal to allow a good vectorization in aqueous media. Benzoxazole dyes are well-known organic fluorophores exhibiting excited-state intramolecular proton transfer (ESIPT) emission. The insertion of these highly hydrophilic OEG chains allows a good solubilization of these dyes in a wide range of solvents of different polarity including PBS buffer/DMSO (95/5) and water, for one of them. The photophysical properties of these ESIPT emitters in solution, and also in the solid-state, as doped as 1 wt% in poly(methylmethacrylate) (PMMA) or polystyrene (PS) films, are discussed. Specifically, the presence of an OEG chain at the 3-position of the benzofuran ring was found to sizeably enhance the fluorescence intensity of the ESIPT emission in the solution state.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 540-37-4. Name: 4-Iodoaniline.

Antiinflammatory and Antiproliferative Activity of Naphthoxazole, Fused Hetero-benzoxazole and Bridged Benzobicyclic Photoproducts

Biological activity of naphthoxazoles, fused hetero-benzoxazoles and benzobicyclo[3.2.1]-derivatives was investigated in proliferation and inflammation based assays. The tested compounds were prepared by photocylization or photocycloaddition reactions. Effect of compounds on proliferation of several cancer cell lines was determined by measuring cell metabolic activity through time. Lipopolysaccharide (LPS) stimulation of peripheral blood mononuclear cells (PBMC) was used to investigate antiinflammatory properties of the compounds. Several naphthoxazoles and fused hetero-benzoxazoles inhibited TNF alpha protein expression in LPS stimulated PBMC, indicating possible antiinflammatory role which would be interesting to further investigate. Physico-chemical properties of tested compounds have been also studied using chromatographic lipophilicity measure, chrom logD and logP was calculated as the importance of physico-chemical properties of compounds at early stage of discovery of new drugs is well established. The similarities in structure and activity of some representative compounds affirm the need to further address their antiinflammatory properties.

Mechanochemical Activation of Polymer-Embedded Photoluminescent Benzoxazole Moieties

Despite an increasing number of studies that have investigated mechanochemical effects in polymers, the number of polymers whose fluorescence characteristics change upon exposure to mechanical stress is still limited. We here report the investigation of a mechanofluorophore based on an aliphatic ester of 2-(2′-hydroxyphenyl)benzoxazole. The free benzoxazole displays green photoluminescence, which is associated with an excited state intramolecular proton transfer (ESIPT) process, whereas aliphatic esters of this compound emit blue light. When poly(methyl acrylate) containing an esterified benzoxazole mechanophore at the center of each chain molecule was exposed to ultrasound, a significant reduction of the molecular weight and pronounced changes of the photoluminescence emission and UV-vis absorption spectra were observed. The optical changes and the fact that the time-traces for molecular weight decrease and formation of the ESIPT capable species mirror each other indicate that the mechanophore is preferentially cleaved upon sonication and that such cleavage restores the 2-(2′-hydroxyphenyl)benzoxazole motif. The concept of mechanical activation of ester-protected ESIPT dyes, and more broadly of other hydroxyl group carrying fluorophores that change their emission properties upon ester formation and cleavage, should be general and allow access to a range of other mechanofluorophores.

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 540-37-4, in my other articles.
