Benzimidazole derivatives as potential anticancer agents.

Benzimidazole ring system is found in many bioactive heterocyclic compounds because of their diverse biological and clinical applications. Furthermore, benzimidazole derivatives are structural isosters of naturally occurring nucleotides, thus they can interact with biological macromolecules such as proteins, enzymes and receptors. This review discusses the benzimidazole derivatives which possess anticancer activity of medicinal efficacy.
