In this paper, new liquid crystal compounds with negative dielectric anisotropy were synthesised by regulating the substituents on the benzofuran ring. Their structures were confirmed by(1)H-nuclear magnetic resonance,(CNMR)-C-13 and mass spectra. The effects of substituent on the properties of liquid crystals were investigated. Compared with the reference compounds, the compounds with 5-ethoxy-6,7-difluorobenzofuran ring exhibit higher clearing points as well as the tendency of expansion of SmA phase range. The density functional theory calculation results reveal that the 6-ethoxy-7-fluorobenzofuran-based compound has smaller aspect ratio than that of the 5-ethoxy-6,7-difluorobenzofuran-based compound, which results in the diminish of the mesophase. Although the dielectric anisotropy of the 5-ethoxy-6,7-difluorobenzofuran-based compound is slightly lower than that of the reference compound, it has both the largest perpendicular and parallel dielectric constant.

Novel azo linked substituted benzimidazole, benzoxazole, and benzothiazole were synthesized by diazo coupling and characterized by H-1 NMR, elemental analysis, FTIR and UV-vis spectroscopy. The newly synthesized compounds were evaluated for invitro antibacterial activity against Staphylococcus aureus and Escherichia Coli strains by Resazurin microtiter assay method (REMA). The minimum inhibitory concentration (MIC in mu g/mL) were used to express the antibacterial activities. The azo linked compounds exhibited good to moderate or high antibacterial activities in vitro. Computational studies were performed to correlate HOMO-LUMO gap with antibacterial activity. The comparative molecular docking studies revealed better insights into binding mechanisms.

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.

In this study, an amide functionalized bis-benzoxazine (AI-al) has been synthesized using allylamine,ortho-amide functional bis-phenol and paraformaldehyde as raw materials via Mannich condensation. This newly obtained benzoxazine has been used to react with polydimethylsiloxane (PDMS) through hydrosilylation to form poly(benzoxazine-co-amide-co-siloxane) (AI-al-PDMS) featuring siloxane, amide and benzoxazine as repeating units. The chemical structures of both oxazine ring-containing monomer and copolymer are confirmed by NMR and FT-IR spectroscopies. Besides, the thermally activated polymerization behaviors of AI-al and AI-al-PDMS are investigated by DSC, and the subsequent conversion of benzoxazole formation is studied by in situ FT-IR. Moreover, dynamic mechanical analysis and thermogravimetric analysis are used to determine the thermal properties of the cross-linked polymers. The resulting cross-linked poly(benzoxazole-co-siloxane) derived from AI-al-PDMS shows excellent thermal stability (noT(g)can be observed before 400 degrees C; Td5 of 393 degrees C) and low dielectric constants (2.52-2.13 in the frequency range of 1 Hz to 1 MHz), evidencing its great potential applications in electronic packing, aerospace, and other high-performance fields.

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.

A novel series of benzoxazolyl linked benzylidene based rhodanine and their cyclic analogs were synthesized, characterized and evaluated for their alpha-amyloglucosidase inhibitory activity. Out of eight target compounds, two compounds (4b and 5b) displayed potent inhibitory activity against alpha-amyloglucosidase with IC50 values in the range of 0.24 +/- 0.01-0.94 +/- 0.01 A mu M as compared to standard drug acarbose. Among all the tested compounds, compound 5b containing rhodanine at 3-position of phenyl was found to be the most active inhibitor of alpha-amyloglucosidase. Docking studies showed the existence of potential H-bonding interactions between synthesized compounds and alpha-glucosidase which might be responsible for good biological activity.

Aims: To quantify pamidronate in a sensitive and accurate way either in bulk or dosage forms. Methodology: The quantification of this group of drugs is a challenging task as they lack the presence of chromophore groups in their structure. The proposed method depends on the derivatization of the studied drug by its reaction with 4-Chloro-7-nitro-2,1,3-benzoxazole and the product is measured spectrophotometrically at 470 nm. The conditions for the reaction are optimized regarding the volume of the reagent, the optimum pH for the reaction completion, the buffer volume, the optimum temperature for the reaction and the optimum heating time. Results: The studied drug can be determined in the range of 9-30 mu g/mL after optimizing the reaction conditions. Method validation is performed according to ICH guidelines and different validation parameters like, linearity, accuracy, precision and robustness are calculated and found to be excellent. Conclusion: The proposed method is accurate, sensitive and can be applied for the routine analysis of pamidronate in quality control laboratories.

Based on benzoxazole and benzothiazole scaffold as an important pharmacophore, two series of 2-(aryloxymethyl) benzoxazole and benzothiazole derivatives were synthesized and their antifungal effects against eight phytopathogenic fungi were evaluated. Compounds 5a, 5b, 5h, and 5i exhibited significant antifungal activities against most of the pathogens tested. Especially 5a, 5b, 5h, 5i, 5j, and 6h inhibited the growth of F. solani with IC50 of 4.34-17.61 mu g/mL, which were stronger than that of the positive control, hymexazol (IC50 of 38.92 mu g/mL). 5h was the most potent inhibitor (IC50 of 4.34 mu/mL) against F. Solani, which was about nine times more potent than hymexazol. Most of the test compounds displayed significant antifungal effects against B. cinerea (IC50 of 19.92-77.41 mu g/mL), among them, 5a was the best one (IC50 of 19.92 mu g/mL). The structure-activity relationships (SARs) were compared and analyzed. The result indicates that the electron-drawing ability and position of the substituents have a significant impact on biological activities. Furthermore, docking studies were carried out on the lipid transfer protein sec14p from S. cerevisiae, and preliminarily verified the antifungal activities. Taken together, these results provide 2-(phenoxymethyl)benzo[d]oxazole as an encouraging framework that could lead to the development of potent novel antifungal agents.

The Pd(OAc)(2)/PhI(OAc)(2) catalyst system promotes the highly regioselective dehydrogenative methoxylation of a C(sp(3))-H bond adjacent to benzoxazole and benzothiazole rings. The title transformation constitutes the first example of a Pd-catalyzed C(sp(3))-H activating methoxylation at the proximal-selective a-position with regard to a directing auxiliary and provides expedient access to an important class of azole-decorated methyl ethers (up to 90% isolated yield). The synthetic practicality of the methodology was demonstrated by achieving a-methoxyacetic acids via the elimination of the benzoxazole auxiliaries and by obtaining the precursor of an O-methylated Breslow intermediate.
