A new series of substituted-N-(3,4-dimethoxyphenyl)-benzoxazole derivatives 13a-13p was synthesized and evaluated in vitro for their COX (I and II) inhibitory activity, in vivo anti-inflammatory and ulcerogenic potential. Compounds 13d, 13h, 13k, 13l and 13n exhibited significant COX-2 inhibitory activity and selectivity towards COX-2 over COX-1. These selected compounds were screened for their in vivo anti-inflammatory activity by carrageenan induced rat paw edema method. Among these compounds, 13d was the most promising analogs of the series with percent inhibition of 84.09 and IC50 value of 0.04 mM and 1.02 mu M (COX-2 and COX-1) respectively. Furthermore, ulcerogenic study was performed and tested compounds (13d, 13h, 13k, 13l) demonstrated a significant gastric tolerance than ibuprofen. Molecular docking study was also performed with resolved crystal structure of COX-2 to understand the binding mechanisms of newly synthesized inhibitors in the active site of COX-2 enzyme and the results were found to be concordant with the biological evaluation studies of the compounds. These newly synthesized inhibitors also showed acceptable pharmacokinetic profile in the in silico ADME/T analyses. (C) 2018 Elsevier Ltd. All rights reserved.

Reaction of a non-innocent o-aminophenol benzoxazole based ligand HLBAP with VOCl3 afforded a vanadyl complex, VOLBIS (SQ), in which SQ is a 2,4-di-tert-butylsemiquinone produced from hydrolysis of HLBAP. The crystal structure of VOLBIS (SQ) exhibits an octahedral geometry with the VO2+ center coordinated by two nitrogen and one oxygen atoms of L-BAP and two oxygen atoms of SQ. Electrochemical studies showed quasi-reversible metal-centered reduction and ligand-centered oxidation of complex. The magnetic moment of VOLBIS (SQ) is consistent with the spin-only value expected for S = 1/2 system. The neutral species of VOLBIS (SQ) is EPR active, which is consistent with a paramagnetic electronic ground state (S = 1/2). This result is in accordance with the vanadyl (IV) moiety surrounded by tridentate iminobenzosemiquinonate anion radical (HLBIS)(center dot-) and benzosemiquinone ligand (SQ)(center dot). The theoretical calculations confirm the experimental results. Furthermore, we present the optimal conditions for maximum efficiency of sulfide oxidation for oxidative desulfurization with hydrogen peroxide and 6 times reusability of catalyst for sulfoxidation of dibenzothiophene.

A series of N-(benzo[d]oxazol-2-ylcarbamothioyl)-2/4-substituted benzamides were synthesized by the reaction of 2-aminobenzoxazole with apposite benzoyl isothiocyanate. The structure of the newly synthesized compounds was confirmed by chemical tests, elemental (C, H, N, and S), and spectral (IR, H-1 NMR, C-13 NMR, and mass) analysis. All the synthesized compounds were evaluated experimentally for their antibacterial activity against Gram-positive and Gram-negative bacteria. The test results show moderate to potent antibacterial activity compared to the standard drug. The binding interactions of newly synthesized ligand and protein were correlated using a molecular docking study using a binding pocket of GlcN-6-P synthase. [GRAPHICS] .

An unexpected BF3.OEt2-catalyzed Michael addition/cyclization/dehydration sequence of ortho-hydroxyenaminones with aromatic or aliphatic aldehyde-derived beta,gamma -unsaturated alpha -ketoesters has been achieved to afford a wide range of fused hydrogenated benzoxazole polycycles in 67-95% yields in a highly diastereoselective manner. When isatin-derived beta,gamma -unsaturated alpha -ketoesters were employed as substrates, completely different reactivities were observed, delivering an array of new atropisomers with an oxindole-substituted N-C axially chiral pyrrole-phenol backbone in up to 97% yield. Moreover, DFT calculations were conducted to account for the possible reaction pathway and the stereochemistry.

This article describes the synthesis and full photophysical studies at room and low temperature of a series of iridium(III) complexes incorporating an ethynyl-extended benzoxazole-based ancillary ligand. The electronic nature of the terminal end-group of the ancillary ligand was modulated by the simple introduction of electron-donating (Me, NBu2) or -withdrawing (CN) groups. For all complexes, TD-DFT calculations showed that the lowest-lying transition was ligand-centered and that the nature of the first triplet state was very sensitive to electronic parameters leading to a charge transfer (CT) or locally excited (LE) excited state, always centered on the ancillary ligand. Singlet oxygen sensitization studies were performed on all compounds, showing that iridium(III) complexes containing cyano-functionalized ligands feature sensitization parameters, making them attractive candidates for photodynamic therapy.

In the given research, the molecular structures of the two new benzo[d]oxazole derivatives including H-I and H-2: have been studied with the use of density functional theory (DFT/B3LYP and M062X) in dimethylformamide (DMF) for the first time. The electronic spectra of the new compounds in a DMF solvent were carried out by temporally dependent density functional theory (TD-DFT) method. The computed absorption spectral data of the title compounds are in good agreement with the experimental data, thus allowing an assignment of the UV/Vis spectra. The equilibrium geometry, the HOMO and LUMO molecular orbitals, excitation energies, oscillator strengths and Natural Bond Orbital (NBO) analysis for the two new molecules have also been calculated and presented. Based on polyvinyl alcohol (PVA) and synthesized molecules polarizers for UV/Vis region of the spectrum have been developed. (C) 2019 Elsevier B.V. All rights reserved. [GRAPHICS]

Mast cells are central regulators of allergic inflammation that function by releasing various proallergic inflammatory mediators, including histamine, eicosanoids and proinflammatory cytokines. Occasionally, bacterial infections may initiate or worsen allergic inflammation. A number of studies have indicated that activation of lipoxygenase in mast cells positive regulates allergic inflammatory responses by generating leukotrienes and proinflammatory cytokines. In the present study, the effects of benzoxazole derivatives on the lipopolysaccharide (LPS)-induced expression of proinflammatory cytokines, production of histamine and surface expression of co-stimulatory molecules on bone marrow-derived mast cells (BMMCs) were studied. The benzoxazole derivatives significantly reduced the expression of interleukin (IL)-1 beta, IL-6, IL-13, tumor necrosis factor-alpha, perilipin (PLIN) 2, and PLIN3 in BMMCs treated with LPS. Furthermore, histamine production was suppressed in BMMCs treated with LPS, or treated with phorbol-12-myristate-13-acetate/ionomycin. Benzoxazole derivatives marginally affected the surface expression of cluster of differentiation (CD)80 and CD86 on BMMCs in the presence of LPS, although LPS alone did not increase the expression of those proteins. Therefore, benzoxazole derivatives inhibited the secretion of proinflammatory cytokines in mast cells and may be potential candidate anti-allergic agents to suppress mast cell activation.

Three 2-fluoroacetonylbenzoxazole ligands 1a-c and their new Zn(II) complexes 2a-c have been synthesized. In addition, syntheses of new metal [Mg(II), Ni(II), Cu(II), Pd(II), and Ag(I)] complexes from la have been also described. The molecular and crystal structures of six metal complexes 2b and 2d-h were determined by single-crystal X-ray diffraction analyses. Their antibacterial activities against six Gram-positive and six Gram-negative bacteria were evaluated by minimum inhibitory concentrations (MIC), which were compared with those of appropriate antibiotics and silver nitrate. The results indicate that some metal compounds have more antibacterial effects in comparison with free ligands and have preferred antibacterial activities that may have potential pharmaceutical applications. Noticeably, the Ag(I) complex 2h exhibited low MIC value of 0.7 mu m against Pseudomonas aeruginosa, which was even superior to the reference drug, Norfloxacin with that of 1.5 mu m. Against P. aeruginosa, 2h is bacteriostatic, exerts the cell surface damage observed by scanning electron microscopy (SEM) and is less likely to develop resistance. The new 2h has been found to display effective antimicrobial activity against a series of bacteria.
