| Hence a series of benzimidazole derivatives have been synthesized characterized by UV, IR and 1H NMR spectral data and evaluated for their and in vitro antioxidant activity. NIH With AU1235 as the lead, we have identified a novel benzimidazole series as potential anti-tuberculosis agents by using scaffold hopping approach. Synthesis of benzimidazoles virtually starts with benzene derivatives having nitrogen-containing functions ortho to each other likeo-phenylenediamines (7) (OPD) and reacting with different carboxylic acids (8) to give 2-substituted benzimidazole derivatives (9), generally in good yield.
