Theoretical and experimental verification of molecular properties of novel benzamide derivatives using computational platforms and in vitro antibacterial activity

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] .

Understanding structure and composition of thermally rearranged polymers based on small-molecule chemistry: a perspective

We provide a critical perspective of the burgeoning literature on microporous polymers prepared using thermal rearrangement (TR) processes based on the learning derived from analogous chemistry involving small-molecular-weight compounds. TR polymers have shown interesting permeability-selectivity relationships in gas separation and, thus, have generated wide interest as potential membrane materials for industrial applications. The intractable nature of the products obtained by TR processes has precluded rigorous structural elucidation of the polymers. Based on small-molecule chemistry, we conclude that structures are likely to be more complex than generally depicted in the published literature. Interestingly, a simpler chemistry, namely thermal dehydrocyclization (TCD), leads to products identical to those derived from TR, but at significantly lower temperatures. However, TCD chemistry does not involve a skeletal rearrangement of the kind purported in TR during the conversion of imide to oxazole ring resulting in spatially confined heterocyclic ring polymers. Yet, they show similar fractional free-volume elements as exhibited by TR polymers. This is intriguing and points to a need for more careful examination of the factors responsible for microporosity in such materials. TR chemistry as currently practiced appears limited to only benzoxazole-type structures. The ability to precisely control and reproducibly produce materials with well-defined structure and properties will be a key to large-scale manufacture and industrial applications of such materials. Seen from this perspective, TR processes leave much to be desired and further improvements are clearly warranted. (c) 2019 Society of Chemical Industry

Site-selective remote C(sp(3))-H heteroarylation of amides via organic photoredox catalysis

Radical translocation processes triggered by nitrogen-centered radicals (NCRs), such as 1,5-hydrogen atom transfers (1,5-HAT), demonstrated by the well-established Hofmann-Loffler-Freytag (HLF) reaction, provide an attractive approach for the controllable and selective functionalization of remote inert C(sp(3))-H bonds. Here we report an amidyl radical-triggered site-selective remote C(sp(3))-H heteroarylation of amides under organic photoredox conditions. This approach provides a mild and highly regioselective reaction affording remote C(sp(3))-H heteroarylated amides at room temperature under transition-metal free, weakly basic, and redox-neutral conditions. Non-prefunctionalized heteroarenes, such as purines, thiazolopyridines, benzoxazole, benzothiazoles, benzothiophene, benzofuran, thiazoles and quinoxalines, can be alkylated directly. Sequential and orthogonal C-H functionalization of different heteroarenes by taking advantage pH value or polarity of radicals has also been achieved. DFT calculations explain and can predict the site-selectivity and reactivity of this reaction. This strategy expands the scope of the Minisci reaction and serves as its alternative and potential complement.

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 105832-38-0. SDS of cas: 105832-38-0.

Synthesis and properties of a novel highly thermal stable N-propargyl monomer containing benzoxazole ring

A novel highly thermal stable propargyl functional compound containing benzoxazole ring, N, N, N, N-tetra propargyl-5-amino-2-(p-aminophenyl) benzoxazole (TPAPB), was proposed and synthesized using a phase-transfer catalytic method. The cure behavior of TPAPB was investigated by non-isothermal differential scanning calorimetry analysis. The solubility and rheological properties of TPAPB, as well as its broad temperature window from 130 degrees C to 200 degrees C with low viscosity, offered excellent processability for TPAPB to be used as a potential monomer of thermosetting polymer resin. It was found that the glass transition temperature of cured TPAPB was 359 degrees C, and the temperature of 5% weight loss was 418 degrees C in argon with the char residue up to 70% at 700 degrees C. The polymerized resin exhibited high heat resistance and thermal stability, together with its processability, making it good candidate as highly heat-resistant polymer matrix for advanced composite applications.

Benzoxazole derivatives suppress lipopolysaccharide-induced mast cell activation

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.

Oxidation of sulfides including DBT using a new vanadyl complex of a non-innocent o-aminophenol benzoxazole based ligand

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.

Ethynyl-Tolyl Extended 2-(2 ‘-Hydroxyphenyl)benzoxazole Dyes: Solution and Solid-state Excited-State Intramolecular Proton Transfer (ESIPT) Emitters

Dual solution/solid-state emissive fluorophores based on a 2-(2 ‘-Hydroxyphenyl)benzoxazole (HBO) core bearing one or two ethynyl-tolyl moieties at different positions were synthesized via an expedite two-step synthetic procedure. HBO derivatives are known to display intense Excited-State Intramolecular Proton Transfer (ESIPT) emission in the solid-state but are mildly emissive in solution due to the detrimental flexibility of the excited-state opening efficient non-radiative pathways. The sole introduction of a rigid ethynyl moiety led to a sizeable enhancement of the fluorescence quantum yield in solution, up to a 15-fold increase in toluene as compared to unsubstituted HBO dyes while keeping the high solid-state fluorescence efficiency. The position of the substitution on the pi-conjugated core led to subtle fine-tuning of maximum emission wavelengths and quantum yields. Moreover, we show that the ethynyl tolyl substituent at the para position of the phenol ring is a suitable moiety for an efficient stabilization of the corresponding emissive anionic HBO derivatives in dissociative solvents like DMF THF or EtOH. These observations were confirmed in CH3CN by a basic titration. For all dyes, the nature of the excited-state involved in the fluorescence emission was rationalized using ab initio calculations.

Phosphorescent Cyclometalated Iridium(III) Complexes Bearing Ethynyl-Extended 2-(2′-Hydroxyphenyl) Benzoxazole Ancillary Ligands

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.

Synthesis, characterization, and gas permeation properties of thermally rearranged poly(hydroxyimide)s filled with mesoporous MCM-41 silica

The gas transport properties of the mixed matrix membranes (MMM) prepared from the synthesized, structurally different poly(hydroxyimide)s (HPI) and mesoporous MCM-41 silica particles were investigated. The both series of filled and unfilled precursors were used to obtain and examine thermally rearranged (TR) polybenzoxazoles (PBO). The effect of a number and position of hydroxyl groups in HPI chains as well as that of filler presence on TR conversion was studied using FTIR, DSC, TGA, WAXD, SEM, mechanical testing, and density measurements. With 7 wt% of MCM-41 silica, gas permeability of the filled HPI precursors and that of the respective filled PBOs increased 1.5-2.2 and 4.4-15.1 times, respectively, comparing to the neat HPIs. The permeability increase along with relatively low loss of gas selectivity for filled membranes shift them towards the upper bound demonstrating that incorporation of porous fillers into polybenzoxazoles precursors can be a new approach to improve membrane performance.

Synthesis, biological evaluation and docking study of a new series of di-substituted benzoxazole derivatives as selective COX-2 inhibitors and anti-inflammatory agents

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.
