In recent years, zinc oxid nanotubes have attracted much attention. The direct use of , zinc oxidnanotubes modified by SiO2 as recoverable catalysts for organic reactions is very rare. The catalystswere characterized by XRD. The average particle size of ZnO catalysts is 57 nm and there are highdensitydefects on nanotubes surfaces . A simple and efficient method for the imidazol derivativessynth...

In this work a novel heterojunction catalyst have been synthesized and employed as a highly efficient catalyst for one-pot synthesis of substituted imidazoles. Analytical methods including Fourier transform infrared (FT-IR), diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), Energy- dispersive X-ray spectroscopy (EDX), Scanning electron microscopy (SEM) and Vibrating Sample Magnom...

A series of 1-substituted 2, 4, 5 triphenyl imidazoles were synthesized by the reaction equimolar mixture of 2, 4, 5 triphenyl imidazole with chloro compound in the presence of anhydrous potassium carbonate. The newly synthesized compounds were characterized on the basis of UV, IR and H NMR spectra. The synthesized compounds were screened for antiinflammatory, antimicrobial activities. Antiinfl...

Moclobemide is a selective and reversible monoamine oxidase-A inhibitor, which is used as an antidepressant. Three moclobemide analogues were synthesized by replacing moclobemide phenyl ring with substituted imidazoles. So, N-[(4-morpholinyl) ethyl)]-1-benzyl-2-(alkylthio)-1H-imidazole-5-carboxamides (7a-c) were synthesized and studied for the antidepressant activity using forced swimming test ...

A series of 2-substituted-4,5-diphenyl imidazoles 1a-j were synthesized by refluxing benzil with different substituted aldehydes in the presence of ammonium acetate and glacial acetic acid. Structures of the synthesized compounds were confirmed on the basis of IR, 1H NMR and mass spectral data. Compounds 1a-j were screened for anthelmintic activity. Test results revealed that compounds showed p...

Cimetidine is the prototype antiulcer drug having the imidazole nucleus and acts by blocking histamine H2 receptors. Keeping this context in mind, an attempt has been made to study the antihistaminic activity of some novel 1-substituted imidazole derivatives on isolated guinea pig atria to reveal their desired pharmacological effects. In the present revision, some 1-substituted Imidazoles (1a-1...
