Novel N-(benzothiazol/oxazol-2-yl) 2 [(5-(phenoxymethyl)-4-aryl-4H-1,2,4-triazol-3-yethio] acetamide derivatives (5a-n) were synthesized and investigated for in vitro anti-inflammatory activity and p38 alpha MAP kinase inhibition. Compounds showing good in vitro activities (5a, 5b, 5d, 5e, 5i, 5k and 5l) were studied for their in vivo anti-inflammatory activity using carrageenan induced rat paw edema model. Compound 5b emerged as the most active compound with an edema inhibition of 84.43%. It also showed improved GI safety profile with lower ulcer severity index and lipid peroxidation potential. Also, p38 alpha MAP kinase assay of 5b showed superior inhibitory potency (IC50:0.031 +/- 0.14 mu M) than the standard SB 203580 (IC50:0.043 +/- 0.14 mu M).

Synthesis of thioethers, arenes and arylated benzoxazoles by transformation of the C(aryl)-C bond of aryl alcohols

Transformation of aryl alcohols into high-value functionalized aromatic compounds by selective cleavage and functionalization of the C(aryl)-C(OH) bond is of crucial importance, but very challenging by far. Herein, for the first time, we report a novel and versatile strategy for activation and functionalization of C(aryl)-C(OH) bonds by the cooperation of oxygenation and decarboxylative functionalization. A diverse range of aryl alcohol substrates were employed as arylation reagentsviathe cleavage of C(aryl)-C(OH) bonds and effectively converted into corresponding thioether, arene, and arylated benzoxazole products in excellent yields, in a Cu based catalytic system using O(2)as the oxidant. This study offers a new way for aryl alcohol conversion and potentially offers a new opportunity to produce high-value functionalized aromatics from renewable feedstocks such as lignin which features abundant C(aryl)-C(OH) bonds in its linkages.

Investigation of thermal and fluorescent properties of benzoxazole-linked triphenylamine-based co-polyimides

A series of novel fluorescent co-polyimides are obtained by combining N (1)-(4-aminophenyl)-N (1)-(4-(benzo[d]oxazol-2-yl) phenyl) benzene-1,4-diamine and 4,4 ‘-oxydianiline with four aromatic anhydride, 3,3 ‘,4,4 ‘-benzophenonetetracarboxylic dianhydride, pyromellitic dianhydride, 4,4 ‘-oxydiphthalic anhydride, and 4,4 ‘-(hexafluoroisopropylidene)diphthalic anhydride following conventional polycondensation method. The resultant co-polyimides are characterized by elemental, Fourier transform infrared spectral analysis and gel permeation chromatography. All newly prepared polyimides (PIs) exhibit shallow highest occupied molecular orbital energy levels in the range of -4.47 to -4.98 eV and have reasonable optical bandgaps. The photoluminescence spectral analysis shows blue to green emission in solution form. Thermal and solubility properties reveal that the PIs with pendant 4-(benzo[d]oxazol-2-yl group linked to triphenylamine unit in polymer backbone impart not only good thermal stability but also appreciable solubility making these new co-polyimides versatile for multipurpose usage.
