Synthesis, biological evaluation and docking study of N-(2-(3,4,5-trimethoxybenzyl)benzoxazole-5-yl) benzamide derivatives as selective COX-2 inhibitor and anti-inflammatory agents

A series of N-(2-(3,4,5-trimethoxybenzy1)-benzoxazole-5-yObenzamide derivatives (3a-3n) was synthesized and evaluated for its in vitro inhibitory activity against COX-1 and COX-2. The compounds with considerable in vitro activity (IC50 < 1 mu M), were evaluated in vivo for their anti-inflammatory and ulcerogenic potential. Out of the fourteen newly synthesized compounds; 3b, 3d, 3e, 3h, 31 and 3m were found to be most potent COX-2 inhibitors in in vitro enzymatic assay with IC 50 in the range of 0.14-0.69 mu M. In vivo anti-inflammatory activity of these six compounds (3b, 3d, 3e, 3h, 31 and 3m) was assessed by carrageenan induced rat paw edema method. The compound 3b (79.54%), 31 (75.00%), 3m (72.72%) and 3d (68.18%) exhibited significant anti-inflammatory activity than standard drug ibuprofen (65.90%). Ulcerogenic activity with histopathological studies was performed, and the screened compounds demonstrated significant gastric tolerance than ibuprofen. Molecular Docking study was also performed with resolved crystal structure of COX-2 to understand the interacting mechanisms of newly synthesized inhibitors with the active site of COX-2 enzyme and the results were found to be in line with the biological evaluation studies of the compounds.

Fluorescence sensing response of zinc(II) and pyrophosphate ions by benzoxazole appended dipodal Schiff base

A novel benzoxazole appended dipodal Schiff base (BS) was synthesized and its sensing property was investigated. The receptor BS detected Zn2+ ions selectively by turn-on fluorescence among the wide range of metal ions in DMSO-H2O (1:9 v/v, 50 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) at pH 7.4. The different physicochemical parameters of BS-Zn2+ complex were investigated by UV-vis, photoluminescence, H-1 NMR titration and ESI-MS techniques. The limit of detection (LOD) and binding constant (K-b) of BS-Zn2+ complex have been determined by fluorescence titration and found to be 4.53 x 10(4) M-1 and 0.52 mu M. Moreover, binding ratio of BS and Zn2+ was found to be 1:1 by Job’s method. Further, the BS-Zn2+ complex was used to sense pyrophosphate (PPi) ions as a secondary sensor in HEPES buffer solution. Overall, the sensitive fluorescence behavior of the receptor BS has been utilized as a powerful tracker for zinc ion and pyrophosphate ion in biological systems.

Carbazole and hydrazone derivatives as new competitive inhibitors of tyrosinase: Experimental clues to binuclear copper active site binding

In this work a total of 12 carbazoles and hydrazone-bridged thiazole-pyrrole derivatives have been identified as new competitive inhibitors of tyrosinase. Carbazole derivative with 2-benzoimidazole substitution showed most potent inhibition in the series. Other carbazole derivatives containing benzothiazole and benzoxazole substitutions showed comparable levels of tyrosinase inhibition. The hydrazone derivatives also showed potent tyrosinase inhibitory activity with comparable K-i values except one with fluoride at its terminal position. Kinetic studies showed competitive inhibition of tyrosinase by all compounds that increased the substrate K-m without changing the V-max value. Moreover, experimental evidence suggests that the target compounds specifically bind to the binuclear copper center of the tyrosinase active site in an apparent mono-dentate fashion. Carbazoles and hydrazones are new and emerging classes of compounds as tyrosinase inhibitors that may provide new structural avenues to discovery of drugs targeting the treatment of hyperpigmentation and related dermatological disorders.

2-Aminobenzimidazole and -benzoxazole as N-nucleophile in palladium-catalysed aminocarbonylation

Palladium-catalysed aminocarbonylation of aryl iodides in the presence of 2-aminobenzimidazole and 2-aminobenzoxazole as N-nucleophile was carried out. Single CO insertion took place, however, instead of the expected carboxamides (C(O)NH) the corresponding N-acyl-imine (C(O)N=C) derivatives were obtained. The structure of the latter compounds can be explained by tautomerization involving the heterocyclic ring. The above structures without amide-NH moieties were proved by methylation at the NH groups of the heterocycle. The resulted mono- and dimethylated benzimidazole derivatives, as well as monomethylated benzoxazole derivatives, like the parent N-acylated compounds, were fully characterised including single crystal X-ray crystallography.

High-throughput screens for agonists of bone morphogenetic protein (BMP) signaling identify potent benzoxazole compounds

Bone morphogenetic protein (BMP) signaling is critical in renal development and disease. In animal models of chronic kidney disease (CKD), re-activation of BMP signaling is reported to be protective by promoting renal repair and regeneration. Clinical use of recombinant BMPs, however, requires harmful doses to achieve efficacy and is costly because of BMPs’ complex synthesis. Therefore, alternative strategies are needed to harness the beneficial effects of BMP signaling in CKD. Key aspects of the BMP signaling pathway can be regulated by both extracellular and intracellular molecules. In particular, secreted proteins like noggin and chordin inhibit BMP activity, whereas kielin/chordin-like proteins (KCP) enhance it and attenuate kidney fibrosis or CKD. Clinical development of KCP, however, is precluded by its size and complexity. Therefore, we propose an alternative strategy to enhance BMP signaling by using small molecules, which are simpler to synthesize and more cost-effective. To address our objective, here we developed a small-molecule high-throughput screen (HTS) with human renal cells having an integrated luciferase construct highly responsive to BMPs. We demonstrate the activity of a potent benzoxazole compound, sb4, that rapidly stimulated BMP signaling in these cells. Activation of BMP signaling by sb4 increased the phosphorylation of key second messengers (SMAD-1/5/9) and also increased expression of direct target genes (inhibitors of DNA binding, Id1 and Id3) in canonical BMP signaling. Our results underscore the feasibility of utilizing HTS to identify compounds that mimic key downstream events of BMP signaling in renal cells and have yielded a lead BMP agonist.

TiO2-ZrO2 composite: Synthesis, characterization and application as a facile, expeditious and recyclable catalyst for the synthesis of 2-aryl substituted benzoxazole derivatives

The activity of an efficient mesoporous TiO2-ZrO2 composite catalyst for the synthesis of 2-aryl substituted benzoxazole derivatives using 2-aminophenol and substituted benzaldehydes/heterocyclic aldehydes at moderate temperature was studied. The catalyst was prepared by a co-precipitation method and characterized by X-ray diffraction, BET surface area and scanning electron microscopy. The effect of temperature, solvents and catalyst concentration on the synthesis of benzoxazole derivatives was systematically investigated. Short reaction times, green-reaction profiles, good to excellent yields, reliable cost efficiency, simple workup conditions and reusability of an eco-friendly catalyst are the noteworthy highlights of the reported method. The catalyst could be easily recovered and reused several times without any significant loss in the yield. The use of the present catalytic system to mediate the title chemical synthesis in a synthetic operation is important for the development of new atom-economic strategies and this is efficient in building complex structures from simple starting materials in an environmentally benign fashion.

Synthesis and in planta antibacterial activity of head-to-head bis-benzimidazole and bis-benzoxazole derivatives

A series of head-to-head bis-benzimidazole and bis-benzoxazole derivatives was synthetized. Their antibacterial activity was examined in planta against Pseudomonas syringae pv. tabaci, the causal agent of wild fire in tobacco and in vitro against Pseudomonas syringae pv. tabaci and Pseudomonas syringae pv. tabaci. All synthetized compounds did not inhibit bacterial growth in vitro. However, they protected Nicotiana benthamiana against P. syringae pv. tabaci in the greenhouse. Only one foliar application at 50 mu g ml(-1) reduced diameter of leaf lesion by 25 to 52% as well as bacterial population in planta by 0.4 to 0.9 logarithmic units. This protection was associated with the inhibition of the accumulation of H2O2 in planta and enhancement of the activity of catalase, ascorbate peroxidase and guaiacol peroxidase. These results suggest that the bis-benzoimidazole and bis-benzoxazole derivatives act as antioxidants and may be used to protect plants against bacterial diseases.

Copper or Silver-Mediated Oxidative C(sp(2))-H/N-H Cross-Coupling of Phthalimide and Heterocyclic Arenes: Access to N-Arylphthalimides

Copper or silver-catalyzed direct C(sp(2))-H/N-H electrochemical cross-coupling of phthalimide and heterocyclic arenes (2-phenylpyridine, benzo[h]quinoline, benzoxazole, and benzothiazole, etc.) for the efficient synthesis of phthalimide derivatives is described. This reaction features good yield, mild conditions, and broad substrate scope, which provides an efficient and straightforward protocol to access this type of tertiary amines. For the first time, the proposed protocol is based not only on a copper catalyst but also on silver, which has never been used for this purpose before, and both give comparable results. Mechanistic investigations (voltammetry, ESR studies) disclosed that a free-radical pathway might be excluded in this process accomplished through Cu(I)/Cu(II)/Cu(III) or Ag(I)/Ag(III) cycles.
