A series of head-to-head bis-benzimidazole and bis-benzoxazole derivatives was synthetized. Their antibacterial activity was examined in planta against Pseudomonas syringae pv. tabaci, the causal agent of wild fire in tobacco and in vitro against Pseudomonas syringae pv. tabaci and Pseudomonas syringae pv. tabaci. All synthetized compounds did not inhibit bacterial growth in vitro. However, they protected Nicotiana benthamiana against P. syringae pv. tabaci in the greenhouse. Only one foliar application at 50 mu g ml(-1) reduced diameter of leaf lesion by 25 to 52% as well as bacterial population in planta by 0.4 to 0.9 logarithmic units. This protection was associated with the inhibition of the accumulation of H2O2 in planta and enhancement of the activity of catalase, ascorbate peroxidase and guaiacol peroxidase. These results suggest that the bis-benzoimidazole and bis-benzoxazole derivatives act as antioxidants and may be used to protect plants against bacterial diseases.

The electronic nature of the recently reported complex, bis((Z)-1-(benzo[d]oxazol-2-yl)-3.3.3-trifluoro-prop-1-en-2-ate)palladium, is re-investigated by a combination of spectroscopy (NMR, IR, magnetic moment, etc.) and Density Functional Theory (DFT: B3LYP 6-31G*/LANL2DZ). In contrast to the recent report, the title complex displays all the properties of diamagnetism and hence retains the properties of a formally Pd(II) square planar complex with a bis-kappa(2)-N,O-donor ligand set. A modified synthetic route is also presented which improves the yield of the compound.

Now introduce a scientific discovery about this category.

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.

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.

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.

Immunosuppressants have shown striking achievements in treating autoimmune diseases in recent years. It is urgent to develop more immunosuppressants to provide more options for patients. PO-296 [2-(6-chlorobenzo[d]oxazol-2-yl)-4,5,6,7-tetrahydro-2H-indazol-3-ol] was identified as a novel benzoxazole derivative. We observed that it exhibits an obvious immunosuppressive activity to T lymphocytes. PO-296 significantly inhibited the proliferation of activated human T lymphocyte without cytotoxicity. Moreover, PO-296 did not affect the expression of cluster of differentiation (CD)-25 or CD69 but induced T lymphocyte cycle arrest in the G0/G1 phase. Furthermore, PO-296 inhibited interleukin (IL)-6, IL-17, and interferon gamma expression but had no effect on IL-2, IL-4, or IL-10. Yet, importantly, PO-296 inhibited the phosphorylation of signal transducer and activator of transcription 5 (STAT5), increased the phosphorylation of p70S6K, but did not affect the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt)/mitogen-activated protein kinase pathway. In conclusion, these findings indicate that PO-296 inhibits human activated T-lymphocyte proliferation by affecting the janus kinase 3 (JAK3)/STAT5 pathway. PO-296 possesses a potential lead compound for the design and development of new immunosuppressants for the treatment of autoimmune diseases.

A new homopolymer, 6FDA-CARDO(t-Bu), was prepared from 6FDA-CARDO through one-step chemical modification by adding bulky tert-butyl groups, using Friedel-Crafts alkylation. The incorporation of the bulky groups led to a significant increase in the fractional free volume (FFV) within the matrix of membranes prepared from the modified polymer. The thermal properties of the modified polymer were not greatly affected compared to those of its parent 6FDA-CARDO homopolymer, where the T-d5% and the T-g were measured to be 517 degrees C and 366 degrees C, respectively. The hydrazine-assisted cleavage of 6FDA-CARDO(t-Bu) led to the preparation of the new diamine monomer CARDO(t-Bu) in high yield. Pure-gas and multicomponent sweet and sour mixed-gas permeation studies of dense films prepared from 6FDA-CARDO(t-Bu) were carried out and compared to those of membranes prepared from 6FDA-CARDO. For example, the carbon dioxide (CO2) pure-gas permeability of the 6FDA-CARDO(t-Bu) membrane was measured at 100 psi feed pressure and 22 degrees C, and found to be 271 Barrer which is 4.6-fold higher when compared to that of 6FDA-CARDO membranes. Due to a simultaneous increase in the methane (CH4) pure-gas permeability, a reduction in the CO2/CH4 selectivity of the 6FDA-CARDO(t-Bu) membrane was recorded. A similar effect was observed for the sweet mixed-gas separation studies. Interestingly, the sour mixed-gas (containing 21% hydrogen sulfide, H2S) separation properties of the 6FDA-CARDO(t-Bu) membrane showed a different trend. At 500 psi and 22 degrees C, the H2S/CH4 selectivity was 10% higher, and the CO2 and H2S permeability coefficients were 3.2- and 3.8-fold, respectively, higher compared to those obtained for 6FDA-CARDO membranes.

We describe herein the synthetic method to benzoxazole derivatives via the copper-catalyzed hydroamination of alkynones with 2-aminophenols. The method produced a wide variety of functionalized benzoxazole derivatives in good yields. Preliminary mechanistic experiments revealed that the reaction would proceed through the copper-catalyzed hydroamination of alkynones and the sequential intramolecular cyclization of beta-iminoketones/elimination of acetophenone promoted by the copper catalyst.

New discoveries in chemical research and development in 2021.

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.
