High-performance poly( benzoxazole/benzimidazole) bio-based plastics with ultra-low dielectric constant from 3-amino-4-hydroxybenzoic acid

High-performance bio-based plastics can make a major contribution to environmental sustainability. A series of high-performance poly(2,5-benzoxazole-co-2,5-benzimidazole)s (PBO-co-PBI) bio-based plastic films, were developed using the aromatic biomolecule 3-amino-4-hydroxybenzoic acid and the commercial product 3,4-diaminobenzoic acid. The partially bio-based PBO-co-PBI films exhibit higher thermal and mechanical performance than conventional bio-based polymers such as polyamide 11 or poly(lactic acid). The robust PBO-co-PBI films exhibit lower dielectric constants (e(r)) than conventional high-performance aromatic polymers, attaining the value comparable to those of polyethylene or polypropylene.

Palladium-Catalyzed Sequential Heteroarylation/Acylation Reactions of lodobenzenes: Synthesis of Functionalized Benzo[d]oxazoles

We report an efficient palladium-catalyzed approach to the synthesis of benzoxazole derivatives via sequential heteroarylation/acylation reaction of iodobenzenes. Three readily available starting materials, iodobenzenes, anhydrides, and benzoxazoles, were smoothly coupled to form new C-C bonds at the ortho and ipso positions of the iodobenzenes to afford 2-heteroaryl-3-acylbenzene derivatives in good yields.

On the Electronic Nature of Bis((Z)-1-(benzo[d]oxazol-2-yl)-3.3.3-trifluoroprop-1-en-2-ate)palladium

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.

Identification and Characterization of a New Series of Ghrelin O-Acyl Transferase Inhibitors

Ghrelin O-acyl transferase (GOAT; MBOAT4) catalyzes O-acylation at serine-3 of des-acyl ghrelin. Acyl ghrelin is secreted by stomach X/A-like cells and plays a role in appetite and metabolism. Therefore, GOAT has been expected to be a novel antiobesity target because it is responsible for acyl ghrelin production. Here, we report homogeneous time-resolved fluorescence (HTRF) and enzyme-linked immunosorbent assay (ELISA) methods utilizing human GOAT-expressing microsomes as a novel high-throughput assay system for the discovery of hit compounds and optimization of lead compounds. Hit compounds exemplified by compound A (2-[(2,4-dichlorobenzyl)sulfanyl]-1,3-benzoxazole-5-carboxylic acid) were identified by high-throughput screening using the HTRF assay and confirmed to have GOAT inhibitory activity using the ELISA. Based on the hit compound information, the novel lead compound (compound B, (4-chloro-6-{[2-methyl-6-(trifluoromethyl)pyridin-3-yl]methoxy}-1-benzothiophen-3-yl)acetic acid) was synthesized and exhibited potent GOAT inhibition with oral bioavailability. Both the hit compound and lead compound showed octanoyl-CoA competitive inhibitory activity. Moreover, these two compounds decreased acyl ghrelin production in the stomach of mice after their oral administration. These novel findings demonstrate that GOAT is a druggable target, and its inhibitors are promising antiobesity drugs.

Substituted 2-Phenacylbenzoxazole Difluoroboranes: Synthesis, Structure and Properties

Novel fluorescent dyes such as benzoxazole-boron complexes, bearing beta-ketoiminate ligands, have been synthesized and characterized with a focus on the influence of a substituent on the basic photophysical properties. H-1, B-11, C-13, N-15, and F-19 nuclear magnetic resonance (NMR) spectra of substituted 2-phenacylbenzoxazole difluoroboranes have been recorded and discussed. It is worth mentioning that a high correlation coefficient was found between N-15-NMR parameters and substituent constants. The photophysical properties of these new dyes have been investigated by fluorescence and ultraviolet-visible (UV-Vis) absorption spectroscopy. The geometry optimization, vibrational spectra, and the HOMO and LUMO energies were calculated based on density functional theory with the use of the B3LYP functional and 6-311++G(d,p) basis set.

Azine based AIEgens with multi-stimuli response towards picric acid

Multifunctional aggregation induced emission luminogens (AIEgens) are novel materials which have significant applications in various fields including biomedical, optoelectronics and sensors. Enormous efforts have been directed towards the strategic development and characterisation of AIEgens, in order to better understand the AIE mechanism. Herein, we studied the photophysical properties of symmetrical azine (D-pi-D) based AIEgens in detail by varying the solvent polarity and viscosity. The AIE behaviour of the azine derivatives relies on the substituents on the nitrogen atom of the amine moiety. Further, these azine derivatives sense the picric acid (PA) with high selectivity and sensitivity in both monomer and aggregated forms. The hydrogen bonding interaction of PA with any one side of the amine nitrogen leads to the formation of a new intramolecular charge transfer state which results in the formation of new absorption and emission spectra. Interestingly in the presence of PA, azine monomers exhibit fluorescence enhancement in pure THF, while aggregated azine molecules show fluorescence quenching in THF-water mixtures.

Novel Pyrazolyl Benzoxazole Conjugates: Design, Synthesis, Molecular Docking Studies and in vitro Anticancer Activities

Nowadays, hybrid drugs have gained a significant role in the treatment of different health problems. Most of the hybrid molecules with different heterocyclic moieties were proved to be potent anti-tumor agents in cancer chemotherapy. Hence, the present study is aimed at the evaluation of in vitro anticancer activity of novel hybrid molecules (pyrazolyl benzoxazole conjugates) and to investigate their anticancer activity by molecular docking studies. Designed, synthesized and characterized the novel pyrazolyl benzoxazole conjugates. Anticancer activity of these compounds was determined by SRB assay. Then molecular docking studies were carried out against proto-oncogene tyrosine-protein kinase (ATP-Src, PDB: 2BDF), a putative target for cancer. All the synthesized compound derivatives were evaluated against MCF-7, KB, Hop62 and A549 cancer cell lines. Compounds 9b and 9c exhibited excellent anticancer activities with GI(50) values of <0.1 mu M against MCF-7 and A549 cell lines. Compound 9e exhibited good antitumor activity on MCF-7 and A-549 with GI(50) values of 0.12 mu M and 0.19 mu M respectively. Compound 9g showed better anticancer activity on A-549 cancer cell line with GI(50) of 0.34 mu M. The two-hybrid molecules 9b and 9c are found to be comparably potent with the standard drug doxorubicin and may act as drug lead compounds in medicinal chemistry aspect. The present docking investigation proved that having benzoxazole of compound 9c at the position of benzofuran of reference compound (N-acetyl pyrazoline derivative) might be valid for contributing to anti-cancer activity.

One-pot Synthesis of 2-Substituted 4H-Chromeno[3,4-d]oxazol-4-ones from 4-Hydroxy-3-nitrocoumarin and Acids in the Presence of Triphenylphosphine and Phosphorus Pentoxide under Microwave Irradiation

2-Substituted 4H-chromeno[3,4-d]oxazol-4-ones are prepared from 4-hydroxy-3-nitrocoumarin and acids by one-pot reaction in the presence of PPh3 and P2O5 under microwave irradiation or by onepot two-step reactions in the presence of Pd/C and hydrogen and then P2O5 under microwave irradiation. The fused oxazolocoumarins were also synthesized from 3-amido-4-hydroxycoumarins and P2O5 under microwave irradiation. The 3-amido-4-hydroxycoumarins are obtained almost quantitatively from 4-hydroxy-3-nitrocoumarin, acids and PPh3 under microwave irradiation, or in the presence of Pd/C and H-2 on heating. Preliminary biological tests indicate significant inhibition of soybean lipoxygenase and antilipid peroxidation for both oxazolocoumarins and o-hydroxyamidocoumarins.
