Discovery of Novel 2-(piperidin-4-yl)-1H-benzo[d]imidazole Derivatives as Potential Anti-Inflammatory Agents

A novel 2-(piperidin-4-yl)-1H-benzo[d]imidazole derivative 5 with good anti-inflammatory activity was identified from our in-house library. Based on hit compound 5, two series of 2-(piperidin-4-yl)-1H-benzo[d]imidazole derivative 6a-g and 7a-h were designed and synthesized as novel anti-inflammatory agents. Most of synthesized compounds exhibited good inhibitory activity on NO and TNF- production in LPS-stimulated RAW 264.7 macrophages, in which the compound 6e showed most potent inhibitory activity on NO (IC50=0.86m) and TNF- (IC50=1.87m) production. Further evaluation revealed that compound 6e displayed more potent in vivo anti-inflammatory activity than ibuprofen did on xylene-induced ear oedema in mice. Additionally, Western blot analysis revealed that compound 6e could restore phosphorylation level of IB and protein expression of p65 NF-B in LPS-stimulated RAW 264.7 macrophages.

Photosensitization of Imidazole Derivative by ZnO Nanoparticle

A sensitive imidazole based fluorescent sensor like 4, 5-diphenyl-2(E)-styryl-1H-imidazole, for ZnO has been designed and synthesized via simple steps. The absorption, fluorescence, SEM, EDX and IR studies indicate that imidazole derivative is bound on the surface of ZnO semiconductor. Based on photo-induced electron transfer (PET) mechanism, fluorescent enhancement has been explained and apparent binding constant has been calculated. Ligand adsorption on ZnO nanoparticle lowers of the HOMO and LUMO energy levels of imidazole derivative and the chemical affinity between the nitrogen atom of the imidazole and zinc ion on the surface of the nano oxide may be a reason for strong adsorption of the ligand on nanoparticle. The electron injection from photo excited imidazole derivative to the ZnO conduction band (S-*-> S+ + e (CB) (-) ) accounts for the enhanced fluorescence.

Imidazole derivatives for efficient organic light-emitting diodes

Since the first development of organic light-emitting diodes (OLEDs) in 1987, imidazole derivatives, mainly including phenanthroimidazole (PI) and benzimidazole (BI), have increasingly attracted attention. Their strong electron-withdrawing properties make them suitable for emitters, hosts, and electron-transporting materials (ETMs). In this review, an overview of the recent developments regarding OLEDs based on imidazole derivatives, especially the relationship between the molecule structure and the device performance as fluorescent and host materials, is given.

Synthesis of fused tetrazole- and imidazole derivatives via iodocyclization

The possibility to prepare fused tetrazole- and imidazole derivatives by iodocyclization in moderate to excellent yields is demonstrated. In some examples the cyclizations were not following Baldwin’s rules entirely, i.e. exo-selectivity. Nucleophilic substitution of the formed iodides gave different results depending on the hardness of the nucleophile. Thus, elimination of the iodide could be a problem but a substitution reaction with ethyl potassium xanthate and a radical reaction using acrylonitrile were tolerated. In addition, we showed that it is possible to selectively use three iodo substituents individually in one of the fused imidazole derivatives. (C) 2003 Elsevier Ltd. All rights reserved.
