Perspectives of Benzimidazole Derivatives as Anticancer Agents in the New Era.

Cancer is one of the deadliest diseases nowadays and is a great topic for research as the challenging task is to develop new entities with selectivity towards cancerous cells. Heterocyclic compounds are of great importance in medicinal chemistry as they possess an extensive range of therapeutic applications. Benzimidazole is one such important heterocyclic organic compound having structural analogy to nucleotides found in human body and hence is an important pharmacophore in medicinal chemistry. A variety of marketed drugs containing benzimidazole are thiabendazole, flubendazole (anthelmintic), astmizole (antihistaminic), lansoprazole and omeprazole (antiulcerative). In the light of the above facts, this review is an attempt to summarize the collective contributions from the authors around the world in the field of anticancer agents. This review highlights synthetic schemes and anticancer activity results of the research done in the past years.
