1. Introduction

Benzimidazole is bicyclic heterocyclic aromatic compound in which benzene ring fused to 4 and 5 position of imidazole ring, it contain two nitrogen atoms at 1 and 3 position exhibit both acidic and basic nature called amphotericin nature and exists in two equivalent tautomeric forms, when the hydrogen present at first position nitrogen atom possess acidic nature, when the hydrogen present at third position nitrogen atom possess basic nature (Figures 1) [1].

3. Conclusions

The benimidazole plays in important role in the field of medicinal chemistry, many of the marketing drugs contain benzimidazole moiety are using to illness. In recent medicinal chemistry research the benzimidazole derivatives are in continuous development with many pharmacological activities such as anti-cancer, anti-HIV, anti-leishmanial, anti-tubercular, anti-malarial, anti-inflammatory, anti-diabetic, and so on, to meet pharmacological requirement. The present literature may helpful to researcher, medicinal chemist, pharmacologist to design, to synthesize, to develop pharmacologically active benzimidazole derivatives with low toxicity in future.
