Graphene oxide (GO) was chemically modified with para-aminobenzoic acid (PABA) to immobilize copper(ii) ions on its surface and used as a nanocatalyst for the oxidative C(sp(2))-H bond amination reaction. A practical method to prepare Cu2+ supported on para-aminobenzoic acid grafted on GO was reported. The prepared Cu2+@GO/PABA was characterized by FT-IR, XRD, SEM, AFM, TEM, UV-Vis, and ICP techniques. The results showed that the morphology, distribution, and loading of copper ions could be well-adjusted by grafting of PABA on GO. Moreover, just 2 mol% of Cu2+@GO-PABA could catalyze the C-H activation reaction of benzoxazole and benzothiazole with secondary amines in >94% yields. Also, the catalyst showed very good recyclability and much less leaching of the Cu into the reaction solution. The high activity of Cu2+@GO-PABA can be ascribed to the good synergistic effects of Cu2+ and para-aminobenzoic acid grafted on graphene oxide.

Now introduce a scientific discovery about this category.

Benzoxazole derivative K313 has previously been reported to possess anti-inflammatory effects in lipopolysaccharide-induced RAW264.7 macrophages. To date, there have been no related reports on the anticancer effects of K313. In this study, we found that K313 reduced the viability of human B-cell leukemia (Nalm-6) and lymphoma (Daudi) cells in a dose-dependent manner without affecting healthy peripheral blood mononuclear cells (PBMCs) and induced moderate cell cycle arrest at the G0/G1 phase. Meanwhile, K313 mediated cell apoptosis, which was accompanied by the activation of caspase-9, caspase-3, and poly ADP-ribose polymerase (PARP). Furthermore, cells treated with K313 showed a significant decrease in mitochondrial membrane potential (MMP), which may have been caused by the caspase-8-mediated cleavage of Bid, as detected by Western blot analysis. We also found that K313 led to the downregulation of p-p70S6K protein, which plays an important role in cell survival and cell cycle progression. In addition, treatment of these cells with K313 blocked autophagic flux, as reflected in the accumulation of LC3-II and p62 protein levels in a dose- and time-dependent manner. In conclusion, K313 decreases cell viability without affecting normal healthy PBMCs, induces cell cycle arrest and apoptosis, reduces p-p70S6K protein levels, and mediates strong autophagy inhibition. Therefore, K313 and its derivatives could be developed as potential anticancer drugs or autophagy blockers in the future.

A borondipyrromethene (BODIPY) chromophore is connected to a benzoxazole, benzothiazole, or nitrobenzothiazole heterocycle through an olefinic bridge with trans configuration. Rotation about the two [C-C] bonds flanking the olefinic bridge occurs with fast kinetics in solution, leading to the equilibration of four conformational isomers for each compound. Ensemble spectroscopic measurements in solutions fail to distinguish the coexisting isomers. They reveal instead averaged absorption and emission bands with dependence of the latter on the excitation wavelength. Using high-throughput single-molecule spectroscopy, two main populations of single molecules with distinct spectral centroids are observed for each compound on glass substrates. Computational analyses suggest the two populations of molecules to be conformational isomers with antiperiplanar and periplanar arrangements of the BODIPY chromophores about its [C-C] bond to the olefinic bridge. Thus, statistical analysis of multiple single-molecule emission spectra can discriminate stereoisomers that would otherwise be impossible to distinguish by ensemble measurements alone.

The present work is devoted to the synthesis and detailed investigation of new 8-benzothiazole containing spiropyrans. The investigated spiropyrans exist under colorless spirocyclic isomers exhibiting positive photochromism with thermo- and photoinduced back reaction. UV light irradiation leads to their effective coloration with quantum yields up to 44%. The efficiency of the back photocyclization induced by visible light does not exceed 0.1%. This feature distinguishes them from the previously studied benzoxazole analogs. The enhancement of electron-withdrawing properties of the indoline fragment substituents promotes an increase in photo-coloration efficiency. The lifetime of the colored form varies from 17 to 200.8 s (acetone, 293 K) depending on substituents. Due to the presence of the benzothiazole moiety, merocyanines can effectively bind Zn2+, Co2+, Ni2+, Cu2+, Cd2+, Mn2+ ions. The addition of salts of these ions to spiropyran solutions results in the stabilization of the merocyanine in the form of intensely colored complexes. Composition, stability and spectroscopic characteristics of complexes have been investigated depending on the metal ion nature and substituents in ligand molecules. The colored complexes possess negative photochromism. The visible light irradiation causes their bleaching with quantum yields up to 48%. The benzothiazole substituted spimpyrans demonstrate ion driving photochromic transformation.

Six complexes of various Mn(II) salts: MnBr2 center dot 4H(2)O (1), Mn(NO3)(2)center dot 4H(2)O (2), MnCl2 center dot 4H(2)O (3) with 2-(1-methyl-2-(pyridin-2-ylmethylene)hydrazinyl)benzo[d]oxazole L-A (complexes 1A-3A) and 2-(24(1H-imidazol-4-yl)methylene)-1-methylhydrazinyl)benzo[d]oxazole HLB (complexes 1B-3B) have been synthesited. All complexes were obtained in 1:1 stoichiometry. Their structures have been established through analytical and spectroscopic (ESI-MS, IR, H-1 NMR and microanalyses) methods as well as by X-ray structure determinations. In order to gain some insights into the electron-richness of studied systems, the electrochemical properties of ligands L-A and HLB and complexes 1A and 1B were investigated by cyclic voltammetry. Complexes 1A and 1B were chosen due to isostructurality what allows to the direct comparison of their behavior. The impact of pyridine and imidazole substituents on electrochemical behavior of synthesized systems was evaluated and showed that the presence of NH moiety in imidazole ring of HLB does not feasible the adsorption on the bare gold electrode.

New liquid crystal compounds with 5,6-difluorobenzofuran core were synthesised by palladium catalysed coupling and ring-closing reaction. Their structures were identified using(1)HNMR,(CNMR)-C-13 and MS. Thermo analysis show that these compounds exhibit a broad nematic range and high clearing points. Physical property test revealed that the dielectric anisotropies of these compounds are about 11 similar to 17, which is twice of that of the 3, 4-difluorinated benzene analogues. DFT calculation results show that the 5, 6-difluorobenzofuran-based compounds have much larger polarisation and dipole moments compared with the common 3,4-difluorobenzene compounds, which leads to a significant increase in dielectric anisotropy and birefringence. As a new fluorinated building block, 5, 6-difluorobenzofuran shows a good prospect for display device. [GRAPHICS] .
