Synthesis and antimicrobial activity of some novel N-substituted benzimidazoles

Synthesis, Characterization and Antimicrobial Activity of d8-10 Metal Complexes of some 2-Substituted-1H-Benzimidazoles

The metal complexes of nine 2-substituted-1H-benzimidazoles (I-IX) with Ni(II), Pd(II), Cu(II), Ag(I), Zn(II) salts were synthesized. The compounds were characterized by melting point, analytical data, IR spectroscopy and magnetic susceptibility. The antimicrobial activity of the compounds was determined by the disk diffusion method in Mueller-Hinton Agar on Staphylococcus aureusATCC 6538, Stap...

Synthesis of Some Novel Tetrazole Substituted Benzimidazoles and Their Evaluation as Antioxidants

A series of tetrazole derivatives (3a-h) were synthesized and screened for antioxidant activity by nitric oxide free radical scavenging activity. All the synthesized compounds were structurally elucidated by spectral techniques such as IR, H NMR spectroscopy and mass spectrometry. The compounds 3b, 3d 3f and 3h exhibited promising antioxidant activities which were found to be comparable with st...

Synthesis and antimicrobial activity of some novel 2,5- and/or 6-substituted benzoxazole and benzimidazole derivatives.

A new series of 2,5- and/or 6-substituted benzoxazoles (7a-f), benzimidazoles (8a-g) holding cyclohexyl or cyclopentyl moieties at position 2 and 5- or 6-substituted-2-cyclohexylaminomethylbenzoxazoles (9a, b) was synthesized in order to determine their antimicrobial activities and feasible structure-activity relationships. The synthesized compounds were tested in vitro against three Gram-posit...
