Benzimidazole: A Promising target for the development of novel drug molecules against breast cancer

Breast cancer is considered as one of the deadliest diseases dominantly in developed and developing countries. Continuous research is required in order to design and develop better therapeutic agents for cancer treatment with more selectivity, efficacy and reduced toxicity. Fused heterocyclic ring system has been identified as a privileged structure by several researchers that can be used as a template for drug discovery and development in Medicinal Chemistry. Wide range of drugs with therapeutic potential contain hetero-aromatic bicyclic ring system as pharmacophore. According to various research outputs in the literature substituted benzimidazoles have wide range of pharmacological profiles with multi-targeting ability, making them an important basic nucleus for the design and development of novel therapeutic agents for the treatment of complex cancers including breast cancer, skin cancer, and blood cancer. In the presented article we have discussed research outputs by many scientists in the last few years that support the candidature of benzimidazole scaffold for the development of novel therapeutic agents against breast cancer along with their mechanism of action. This review also focuses on little introductory idea about benzimidazole nucleus and types of breast cancer.
