A biradical oxo-molybdenum complex containing semiquinone and o-aminophenol benzoxazole-based ligands

We report a new mononuclear molybdenum(iv) complex, (MoOLLSQ)-L-BIS, in which L-SQ (2,4-di-tert-butyl o-semibenzoquinone ligand) has been prepared from the reaction of the o-iminosemibenzoquinone form of a tridentate non-innocent benzoxazole ligand, L-BIS, and MoO2(acac)(2). The complex was characterized by X-ray crystallography, elemental analysis, IR and UV-vis spectroscopy and magnetic susceptibility measurements. The crystal structure of (MoOLLSQ)-L-BIS revealed a distorted octahedral geometry around the metal centre, surrounded by one O and two N atoms of L-BIS and two O atoms of L-SQ. The effective magnetic moment (mu(eff)) of (MoOLLSQ)-L-BIS decreased from 2.36 to 0.2 mu(B) in the temperature range of 290 to 2 K, indicating a singlet ground state caused by antiferromagnetic coupling between the metal and ligand centred unpaired electrons. Also, the latter led to the EPR silence of the complex. Cyclic voltammetry (CV) studies indicate both ligand and metal-centered redox processes. (MoOLLSQ)-L-BIS was applied as a catalyst for the oxidative cleavage of cyclohexene to adipic acid and selective oxidation of sulfides to sulfones with aqueous hydrogen peroxide.

Facile Access to 2-Substituted Benzoxazoles Using Sawdust Supported N-Heterocyclic Carbene-Ni Complex via C-H Activation

Sawdust supported N-heterocyclic carbene-nickel complex has been prepared by covalent grafting of 1-methyl imidazole in the matrix of chloropropyl modified sawdust followed by reaction with nickel acetate. The resultant NHC-Ni complex was employed as a heterogeneous catalyst for the synthesis of 2-substituted benzoxazoles from benzoxazole and aryl boronic acids following C-H activation strategy. The recycling experiments showed that the complex could be reused for five consecutive runs without significant loss in the yield of products.

Identification of novel 2-benzoxazolinone derivatives with specific inhibitory activity against the HIV-1 nucleocapsid protein

In this report, we present a new benzoxazole derivative endowed with inhibitory activity against the HIV-1 nucleocapsid protein (NC). NC is a 55-residue basic protein with nucleic acid chaperone properties, which has emerged as a novel and potential pharmacological target against HIV-1. In the pursuit of novel NC-inhibitor chemotypes, we performed virtual screening and in vitro biological evaluation of a large library of chemical entities. We found that compounds sharing a benzoxazolinone moiety displayed putative inhibitory properties, which we further investigated by considering a series of chemical analogues. This approach provided valuable information on the structure-activity relationships of these compounds and, in the process, demonstrated that their anti-NC activity could be finely tuned by the addition of specific substituents to the initial benzoxazolinone scaffold. This study represents the starting point for the possible development of a new class of antiretroviral agents targeting the HIV-1 NC protein. (C) 2017 Elsevier Masson SAS. All rights reserved.

Three new mixed-ligand copper(II) complexes containing glycyl-l-valine and N,N-aromatic heterocyclic compounds: Synthesis, characterization, DNA interaction, cytotoxicity and antimicrobial activity

Three novel copper(II) complexes, [Cu(Gly-l-Val)(HPBM)(H2O)]ClO4H2O (1), [Cu(Gly-l-Val)(TBZ)(H2O)]ClO4 (2) and [Cu(Gly-l-Val)(PBO)(H2O)]ClO4 (3) (Gly-l-Val=glycyl-l-valine anion, HPBM=5-methyl-2-(2-pyridyl)benzimidazole, TBZ=2-(4-thiazolyl)benzimidazole, PBO=2-(2-pyridyl)benzoxazole), have been prepared and characterized with elemental analyses, conductivity measurements as well as various spectroscopic techniques. The interactions of these copper complexes with calf thymus DNA were explored using UV-visible, fluorescence, circular dichroism, thermal denaturation, viscosity and docking analyses methods. The experimental results showed that all three complexes could bind to DNA via an intercalative mode. Moreover, the cytotoxic effects were evaluated using the MTT method, and the antimicrobial activity of these complexes was tested against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The results showed that the activities are consistent with their DNA binding abilities, following the order of 1 > 2 > 3.

Synthesis and biological evaluation of new N-benzylpyridinium-based benzoheterocycles as potential anti-Alzheimer’s agents

A novel series of benzylpyridinium-based benzoheterocycles (benzimidazole, benzoxazole or benzothiazole) were designed as potent acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibitors. The title compounds 4a-q were conveniently synthesized via condensation reaction of 1,2-phenylenediamine, 2-amino-phenol or 2-aminothiophenol with pyridin-4-carbalehyde, followed by N-benzylation using various benzyl halides. The results of in vitro biological assays revealed that most of them, especially 4c and 4g, had potent anticholinesterase activity comparable or more potent than reference drug, donepezil. The kinetic study demonstrated that the representative compound 4c inhibits AChE in competitive manner. According to the ligand-enzyme docking simulation, compound 4c occupied the active site at the vicinity of catalytic triad. The compounds 4c and 4g were found to be inhibitors of A beta self-aggregation as well as AChE-induced A beta aggregation. Meanwhile, these compounds could significantly protect PC12 cells against H2O2-induced injury and showed no toxicity against HepG2 cells. As multi-targeted structures, compounds 4c and 4g could be considered as promising candidate for further lead developments to treat Alzheimer’s disease.

Fluorescent Heteroleptic Zirconium and Hafnium Complexes

Five new heteroleptic zirconium and hafnium complexes were synthesized. The complexes carry chloro ligands as well as differently substituted phenoxy benzoxazole ligands [HL1 = 2-(2-hydroxyphenyl)benzoxazole, HL2 = 2-(2-hydroxynaphthyl)benzoxa-zole, HL3 = 2-(2-hydroxy-3,5-di-tert-butylphenyl)benzoxazole]. They were characterized by H-1 and C-13{H-1} NMR spectroscopy as well as by elemental analyses and X-ray diffraction experiments. The molecular structures in the crystals show distorted octahedral or capped trigonal prismatic coordination spheres. The intermolecular interactions influencing the packing patterns are mainly HCl contacts. For the hafnium complex [Cl2Hf(L3)(2)] a dynamic behavior in solution was examined using temperature dependent H-1 NMR spectroscopy. The photo-physical data show that in all cases fluorescence arises from a short-lived excited state, the emission maxima being located in the blue spectral region.

Densification-induced hollow fiber membranes using crosslinked thermally rearranged (XTR) polymer for CO2 capture

Since thermally rearranged (TR) polymers were known as high gas permeable and processable materials, fabricating high performance hollow fiber (HF) membranes have been tried using them. However, an unexpected drawback emerged which is the gas productivity loss by thermal densification of skin layers during thermal treatment above their glass transition temperature (T-g). In this work, we used a recently reported crosslinked-TR (XTR) polybenzoxazole to develop a new class of high-flux TR hollow fibers by directly exploiting the thermal densification phenomenon. The TR temperature range (320-460 degrees C) and T-g (394 degrees C) were determined by thermal gravimetric analysis (TGA) and dynamic mechanical analysis (DMA). The chain rigidity of the XTR polymer increased during an isotherm treatment at its T-g, suggesting a restricted densification. Surprisingly, the undesired pinhole-defects (pore diameter < 5 nm) on precursor fibers were perfectly healed after thermal treatment (> 400 degrees C), forming an ultrathin defect-free skin layer on thermally-densified XTR hollow fiber membranes. The pore-healed XTR hollow fibers exhibited an outstanding CO2 permeance of similar to 2300 GPU and a CO2/N-2 selectivity of 17.4 with a skin thickness of 103 nm.

Laser-induced linear and non-linear optical features in novel benzoxazole-based on donor-acceptor chromophores

The photophysical properties of donor-acceptor based benzoxazoles were investigated by means of steady-state and time-resolved fluorescence techniques. Additionally, laser stimulated second-order optical effects (preliminary second harmonic generation (SHG) were studied. The studies show that the nitro-benzoxazole derivatives decorated with different alkylo/arylo amino groups dissolved in medium polar aprotic solvents: tetrahydrofuran and butyl chloride, exhibit dual fluorescence from the locally excited state ((LE)-L-1) and a highly polar charge transfer (CT) state. Ambient-temperature time resolved fluorescence investigations prove the bimodal kinetics of the excited-state electron transfer reaction (LE)-L-1 ->(CT)-C-1. The lack of any CT emissions in cyclohexane and highly polar acetonitrile is presumably due to an efficient inter-system crossing process or fast deactivation of a low-lying CT state. In addition, strong CT properties inspired us to check a possibility to vary the absorption of the first UV-Vis maxima under influence of the external bicolour coherent laser light and the related optical second harmonic generation (SHG). The two coherent beams of the infrared Er:glass laser at 1540 nm/770 nm formed gratings in the photopolymer solidified chromophore. The performed experiments are compared with the theoretically calculated electronic parameters within the B3LYP DFT approach. The presented data open novel type of materials, allowing to operate its transparency using external IR laser light in the near IR spectral range. (C) 2018 Elsevier B.V. All rights reserved.

A novel series of 2-sulfonyl benzoxazoles containing 1,2,3-triazole nucleus was synthesized using highly efficient and environmentally benign microwave-assisted ionic liquids containing click synthesis. The newly synthesized compounds were screened for their anti-inflammatory and antibacterial activities. Among all the derivatives tested, compound 5c containing the 4-fluorophenyl group in the triazole ring exhibited the most potent anti-inflammatory activity and the remaining compounds have shown moderate to good activity compared to the reference drug. The antibacterial activity revealed that compound 5c has shown more potent activity than the standard drugs. [GRAPHICS]
