Abstract

The therapeutic potential of the benzimidazole nucleus has been recognized since 1944, and it is an important heterocycle system due to its presence in a wide range of bioactive compounds such as antiviral, anticancer, antibacterial, and so on, where optimization of substituents in this class of pharmacophore has resulted in many drugs. Its broad biological activity stems from physicochemical properties such as hydrogen bond donor-acceptor capability, π→π stacking interactions, coordination bonds with metals as ligands and hydrophobic interactions; properties that allow them to easily bind with a series of biomolecules, including enzymes and nucleic acids, causing a growing interest in these types of molecules. This review aims to present an overview to leading benzimidazole derivatives, as well as to show the importance of the nature and type of substituents at the N1, C2, and C5(6) positions when they are biologically evaluated, which can lead to obtaining potent drug candidate with a significant range of biological activities.

Keywords: Benzimidazole, heterocycle, biological activity, medicinal chemistry, structure-activity relationship.
