A series of N-(2-(3,5-dimethoxyphenyl)benzoxazole-5-yl)benzamide derivatives (3am) was synthesized and evaluated for their in vitro inhibitory activity against COX-1 and COX-2. The compounds with considerable in vitro activity (IC50<1M) were evaluated in vivo for their anti-inflammatory potential by the carrageenan-induced rat paw edema method. Out of 13 newly synthesized compounds, 3a, 3b, 3d, 3g, 3j, and 3k were found to be the most potent COX-2 inhibitors in the in vitro enzymatic assay, with IC50 values in the range of 0.06-0.71M. The in vivo anti-inflammatory activity of these six compounds (3a, 3b, 3d, 3g, 3j, and 3k) was assessed by the carrageenan-induced rat paw edema method. Compounds 3d (84.09%), 3g (79.54%), and 3a (70.45%) demonstrated significant anti-inflammatory activity compared to the standard drug ibuprofen (65.90%) and were also found to be safer than ibuprofen, by ulcerogenic studies. A docking study was done using the crystal structure of human COX-2, to understand the binding mechanism of these inhibitors to the active site of COX-2. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

New discoveries in chemical research and development in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals. In an article, author is Xu, Ruisong, once mentioned the application of 75178-96-0, Category: benzoxazole, Name is tert-Butyl (3-aminopropyl)carbamate, molecular formula is C8H18N2O2, molecular weight is 174.2407, MDL number is MFCD00210021, category is benzoxazole. Now introduce a scientific discovery about this category.

A novel gas separation membrane was fabricated from a commercially available polymer of phenolphthalein-based cardo poly (arylene ether ketone) (PEK-C). Thermal treatment was employed to improve the gas permeability and anti-plasticization property of PEK-C polymeric membrane via inducing interchain crosslinking. The changes of chemical structure, thermal crosslinking reaction, interchain distance, gas separation performance and anti-plasticization properties of PEK-C membranes were investigated by the FT-IR, XPS, TG-MS, XRD and gas permeation tests. Results show that the gas separation performance and anti-plasticization properties of PEK-C membranes are significantly enhanced after the thermal crosslinking, which is induced by the decomposition of the lactone rings in cardo moieties and crosslinking with the formation of biphenyl linkages. The dramatic enhancement in gas permeability for the crosslinked membrane is attributed to the enlargement of the interchain distance and free volume cavity, and the great improvement on the anti-plasticization property is due to the formation of a rigid crosslinked network structure. Compared to PEK-C polymeric membrane, the CO2 permeability of the crosslinked membrane increased by more than 110 times with an adequate CO2/CH4 selectivity, especially for the separation of CO2/CH4 mixed gas (50:50 mol%). The CO2 plasticization pressure substantially increased from 2 atm to the highest tested pressure of 30 atm. The gas separation performance of the crosslinked membrane surpassed the 2008 upper bound for CO2/CH4, exhibiting that the thermal crosslinking membrane derived from PEK-C membrane material is an attractive candidate for the natural gas purification.

The p53 tumor suppressor plays critical roles in cell cycle regulation and apoptotic cell death, with its activation capable of sensitizing cancer cells to radiotherapy or chemotherapy. To identify small molecules that induce apoptosis via increased p53 transcriptional activity, we used a novel in-house library containing 96 small-molecule compounds. Using a cell-based screening method with a p53-responsive luciferase-reporter assay system involving benzoxazole derivatives, we found that AU14022 administration significantly increased p53 transcriptional activity in a concentration-dependent manner. Treatment with AU14022 increased p53 protein expression, p53 Ser15 phosphorylation, p53-mediated expression of downstream target genes, and apoptosis in p53-wild-type HCT116 human colon cancer cells, but not in p53-knockout HCT116 cells. Additionally, p53-wild-type HCT116 cells treated with AU14022 exhibited mitochondrial dysfunction, including modulated expression of B-cell lymphoma-2 family proteins and cytochrome c release. Combination treatment with AU14022 and ionizing radiation (IR) synergistically induced apoptosis as compared with IR or AU14022 treatment alone, with further investigation demonstrating that cell cycle progression was significantly arrested at the G2/M phase following AU14022 treatment. Furthermore, in a mouse p53-wild-type HCT116 colon cancer xenograft model, combined treatment with AU14022 and IR inhibited tumor growth more effectively than radiation alone. Therefore, AU14022 treatment induced apoptosis through p53-mediated cell cycle arrest involving mitochondrial dysfunction, leading to enhanced radiosensitivity in colon cancer cells. These results provide a basis for further assessments of AU14022 as a promising anticancer agent.

Based on the Gaussian-based quantitative structure-activity relationship (QSAR) and virtual screening (VS) processes, some promising acetylcholinesterase inhibitors (AChEls) having antioxidant potential were designed synthesized, characterized, and evaluated for their ability to enhance learning and memory. The synthesized phenyl benzoxazole derivatives exhibited significant antioxidant potential and AChE inhibitory activity, whereas the antioxidant potential of compound 34 (49.6%) was observed significantly better than standard donepezil (<10%) and parallel to ascorbic acid (56.6%). Enzyme kinetics study of most potent compound 34 (AChE IC50 = 0.363 +/- 0.017 mu M; Ki = 0.19 +/- 0.03 mu M) revealed the true nature and competitive type of inhibition on AChE. The compound 34 was further assessed for in vivo and ex vivo studies and the results showed the significant reversal of cognitive deficits and antioxidant potential at the dose of 5 mg/kg comparable to standard drug donepezil.

A series of ten heteroleptic and homoleptic mononuclear Zr(iv) and Hf(iv) complexes bearing differently substituted phenoxy-benzoxazole ligands was synthesised. The complexes were characterised by H-1 and C-13{H-1} NMR spectroscopy as well as by elemental analyses and X-ray diffraction experiments. The molecular structures show octahedral or tetragonal-antiprismatic coordination motifs at the metal atom. The crystal packing patterns depend on the substitution of the ligands. The intermolecular interactions in the solid state are governed by weak – interactions, and are also dependent on the ligand structure. Photo-physical investigations reveal that all ten complexes show a ligand-centered fluorescence with emission maxima in the blue region of the electromagnetic spectrum.

There is current interest in developing human hypoxia-inducible factor (HIF) prolyl hydroxylase domain (PHD) inhibitors for the treatment of anemia and other hypoxia-related diseases. We describe the synthesis of 3-carbamoylpropanoic acid derivatives and their evaluation as human PHD-2 inhibitors. MS assays indicated that derivatives with a 3-carbamoylpropanoic acids-containing benzoxazole moiety are inhibitors of PHD-2 with IC50 values of 2.24 mu M and 1.32 mu M, respectively. However, neither the acids nor their respective ethyl esters were observed to upregulate HIF-1 alpha levels in cells.

We previously reported 2-aminobenzoxazole analogue 1 as a potent ChemR23 inhibitor. The compound showed inhibitory activity against chemerin-induced calcium signaling through ChemR23 internalization in CAL-1 cells, which are cell lines of plasmacytoid dendric cells (pDCs). Furthermore, compound 2 inhibited chemotaxis of CAL-1 triggered by chemerin in vitro. However, we noted a difference in the ChemR23 response to our inhibitor between rodents and non-rodents in a previous study. To address this issue, we performed optimization of ChemR23 inhibitors using CAL-1 cells endogenously expressing human ChemR23 and conducted a pharmacokinetics study in cynomolgus monkeys. Various substituents at the 4-position of the benzoxazole ring exhibited potent in vitro bioactivity, while those at the 6-position were not tolerated. Among substituents, a carboxyl group was identified as key for improving the oral bioavailability in cynomolgus monkeys. Compound 38a with the acidic part changed from a tetrazole group to a 1,2,4-oxadiazol-5-one group to improve bioactivity and pharmacokinetic parameters exhibited inhibitory activity against chemerin-induced chemotaxis in vitro. In addition, we confirmed the ChemR23 internalization of pDCs by compound 38a orally administered to cynomolgus monkeys. These 2-aminobenzoxazole-based ChemR23 inhibitors may be useful as novel immunotherapeutic agents capable of suppressing the migration of pDCs, which are known to be major producers of type I interferons in the lesion area of certain autoimmune diseases, such as systemic lupus erythematosus and psoriasis.

Owing to their much more accessible structural diversity and recognition mechanism, the fluorescent probes with small molecular scaffold are significant, and they have been broadly investigated in the cutting edge of materials and biological chemistry. Known as the facile synthesis, expedient structural modification, good molecular stability, admirable fluorescence properties, multiple binding sites and excellent environmental compatibility, the benzazole moieties are under growing attraction in fluorescent probes for efficient detection of different species, such as cations (H+, Al3+, Hg2+, Cu2+, etc.), anions (HSO3-, F-, OH-, CN- , etc.), biomolecules (thiols, amino acids, etc.) and explosives (picric acid and TNT, etc.). In this review, benzimidazole-, benzoxazole- and benzothiazole-based fluorescent probes that have been reported in the recent three years (2017-2019) are refined to elucidate the progress of benzazole-based probes by combining their design strategy, synthetic route, sensing mechanism and applications. We wish that it may afford valuable recommendation to the construction of intelligent and versatile fluorescent probes based on benzazole derivatives.

A series of benzoxazole derivatives and some possible primary metabolites were evaluated as anticancer agents. In vitro anti-proliferative activities of the compounds were tested using the SRB assay on cancerous (HeLa) and non-cancerous (L929) cell lines. It was found that 17 of 21 tested compounds had cytotoxic activity on HeLa cells and the cytotoxic activities of the compounds were 15-700 times higher than on L929 cells. We generated two distinct pharmacophore models for the cytotoxic activities of the compounds on HeLa and L929 cells. While active compounds such as camptothecin and X8 fitted the two models generated for both cell lines, selective cytotoxic compounds such as XT3B fitted only the model generated for HeLa cells. Evaluation of the genotoxic activities of the cytotoxic compounds with the alkaline comet assay revealed that compounds X17 and XT3 showed strong genotoxic effects against HeLa cells at low concentrations whereas they had no genotoxic effect on L929 cells. Due to the selective ability for inducing DNA strand breaks only on cancerous cells, the compounds were identified as effective derivatives for anticancer candidates.
