Novel N-((2-(aryl)-imidazol-1-yl) methyl)-anilines 2a-n and 1-(3'-arylamino-2'- hydroxypropyl)-2-methyl-4-nitroimidazoles 4a-g have been synthesized. The compounds have been characterized on the basis of elemental analysis and spectral data. All the compounds were evaluated for their antibacterial activities. Among the synthesized compounds, compounds 2m, 2n and compounds 4c, 4e exhibited highest inhibitory activity against all the bacterial strains, comparable to the standard drug ciprofloxacin. Binding mode analysis of the highest active compounds was carried out in the active site of GlcN-6-P synthase (2VF5).

The oxidation of 2-substituted imidazolines with sodium periodate catalyzed by tetrakis(p-aminophenyl)-porphyrinatomanganese(III) chloride, [Mn(TNH 2PP)Cl], supported on functionalized multi-wall carbon nanotubes is reported. A wide variety of 2-imidazolines were efficiently converted to their corresponding imidazoles by this catalytic system. When the same reaction was subjected to ultrasonic irradiation, the reaction times were reduced significantly and the product yields were increased. This catalyst could be reused several times without significant loss of activity. The effects of reaction parameters such catalyst amount, choice of solvent, and the effects of ultrasonic irradiation on the catalytic activity have been investigated.

Rapid and efficient oxidation of 2-substituted imidazolines with sodium periodate is reported. The Mn(III)-salophen/NaIO4 catalytic system efficiently converted 2-imidazolines to their corresponding imidazoles at room temperature in 2: 1, CH3CN/H2O mixture.

In the present work, dehydrogenation of 2-substituted imidazolines with sodium periodate in the presence of tetraphenylporphyrinatomanganese(III) chloride, [Mn(TPP)Cl], is reported. A wide variety of 2-imidazolines efficiently converted to their corresponding imidazoles by [Mn(TPP)Cl]/NaIO4 catalytic system at room temperature in 1:2, CH3CN/H2O mixture. The effect of reaction parameters such as kind of solvent and catalyst amount was also investigated.

experimental part, p. 1463 - 1468 (2011/06/27)
In the present work, the dehydrogenation of 2-substituted imidazolines with sodium periodate in the presence of tetraphenylporphyrinatomanganese(III) chloride supported on polystyrene-bound imidazole, [Mn(TPP)Cl@PSI] is reported. A wide variety of 2-imidazolines were efficiently converted to their corresponding imidazoles by the [Mn(TPP)Cl@PSI]/NaIO4 catalytic system in a 1:2 CH3CN/H2O mixture under agitation with magnetic stirring. Ultrasonic irradiation enhanced the catalytic activity of this catalyst in the oxidation of 2-imidazolines and this led to shorter reaction times and higher product yields. This catalyst could be reused several times without significant loss of its catalytic activity.

experimental part, p. 720 - 727 (2012/04/04)
A series of [2-(substituted phenyl)-imidazol-1-yl]-pyridin-3-yl-methanones (111) were synthesized and screened for their antimicrobial and antimycobacterial activities. Further, a series of [2-(substituted phenyl)-benzimidazol-1-yl]-pyridin-3-yl-methanones (1220) reported in our earlier study was also screened for their antimycobacterial activity. The antimycobacterial activity results indicated that [2-(4-Nitro-phenyl)-imidazol- 1-yl]-pyridin-3-yl-methanone (8, minimum inhibitory concentration [MIC]=3.13 g) was equipotent as standard drug ciprofloxacin and [2-(4-Nitro-phenyl)- benzimidazol-1-yl]-pyridin-3-yl-methanone (16, MIC=1.56 g) was equipotent as standard drug ethambutol. The results of antimicrobial screening demonstrated that 2-[1-(Pyridine-3-carbonyl)-1H-imidazol-2-yl]-benzoic acid (compound 11, MIC=0.002 g) was two times more effective than standard drug ciprofloxacin (MIC=0.004 g) against tested bacterial strains and [2-(2,5-Dimethyl-phenyl)- imidazol-1-yl]-pyridin-3-yl-methanone (compound 3, MIC=0.005 g) was equipotent to the reference compound, fluconazole against tested fungal strains.

experimental part, p. 2347 - 2353 (2009/12/03)
In the present study, we have synthesized 2-(substituted phenyl)-1H-imidazole (1-12) and (substituted phenyl)-[2-(substituted phenyl)-imidazol-1-yl]-methanone (13-26) analogues and screened them for their antimicrobial activity against Gram positive, Gram negative and fungal species. The results of antibacterial study indicated that compounds 15, 17 and 24 showed appreciable antibacterial activity and compound 26 emerged as the most potential antifungal agent. The results of SAR studies indicated that the presence of electron withdrawing groups is necessary for the antimicrobial activity of the synthesized compounds. The results of the present study indicated that compounds 15, 17 and 24 might be of interest for the identification of new antimicrobial molecules as their antibacterial activity is equivalent to the standard drug norfloxacin. Further, the antiviral screening of (substituted phenyl)-[2-(substituted phenyl)-imidazol-1-yl]-methanones (13-26) against a panel of viral strains indicated that compounds 16 and 19 can be selected as lead compounds for the development of novel antiviral agents.

, p. 110 - 114 (2007/10/03)
Different types of 2-imidazolines, bis-imidazolines, and N-substituted-2-imidazolines are efficiently oxidized to their corresponding imidazoles with potassium permanganate (KMnO4) supported on montmorillonite K-10 under very mild conditions. The procedure is very simple and no strict conditions were required. Selective dehydrogenation of 2-alkyl-2-imidazolines in the presence of 2-aryl-2-imidazolines is a noteworthy advantage of this method and can be considered as a useful practical achievement in these reactions.
